- SourceHolder.isSourceChanged改为计数器，避免布尔标志竞争条件
- 两个页面切换源时递增计数器，所有页面同时刷新
- Home页面站源改为Surface+SourceSwitchDialog，与Week页面统一
- Home页面站源添加圆角矩形焦点背景
- 移除Week页面源切换的确认/取消按钮，选中即切换

+# [S1] 动漫源切换统一改造
+
+## [S2] 问题
+
+- Week 和 Home 页面切换源功能不统一：Week 页面用 AlertDialog + RadioButton，Home 页面无切换功能
+- 切换源后只有当前页面刷新，其他页面不同步
+- Week 页面切换源需要点击确认按钮，操作繁琐
+- Home 页面站源文本无焦点样式，不能使用 D-pad 操作
+
+## [S3] 改动的文件
+
+| 文件 | 改动 |
+|------|------|
+| `util/SourceHolder.kt` | `isSourceChanged` 改为 `mutableStateOf(0)` 计数器 |
+| `screen/week/WeekScreen.kt` | `SourceSwitchDialog` 改为 public，添加 `onSourceChanged` 回调，移除确认/取消按钮 |
+| `screen/home/HomeScreen.kt` | 站源文本改为 `Surface(onClick)` + `SourceSwitchDialog`，添加 `focusGroup()` |
+| `screen/home/HomeScreen.kt` | 站源使用 `surfaceVariant.copy(alpha = 0.6f)` 焦点背景色 |
+
+## [S4] 关键实现
+
+1. **跨页面刷新**: `SourceHolder.isSourceChanged` 用 `mutableStateOf(0)` 递增计数器代替布尔值
+2. **Week 页面**: `SourceSwitchDialog` 改为 public，选中 RadioButton 立即切换并刷新
+3. **Home 页面**: 站源名称用 `Surface(onClick) + RoundedCornerShape(20.dp)` + `sourceSwitchDialog` 弹出相同源选择列表
+4. **焦点背景**: `onFocusChanged` + `surfaceVariant.copy(alpha = 0.6f)` 统一圆角矩形效果

+description: Implement tasks from an OpenSpec change (Experimental)
+---
+
+Implement tasks from an OpenSpec change.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx:continue`
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read every file path listed under `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! You can archive this change with `/opsx:archive`.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+description: Archive a completed change in the experimental workflow
+---
+
+Archive a completed change in the experimental workflow.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name after `/opsx:archive` (e.g., `/opsx:archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
+   ```bash
+   mkdir -p "<planningHome.changesDir>/archive"
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+

+
+**Options:**
+1. Rename the existing archive
+2. Delete the existing archive if it's a duplicate
+3. Wait until a different date to archive
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use the Skill tool to invoke `openspec-sync-specs` (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+description: Enter explore mode - think through ideas, investigate problems, clarify requirements
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: The argument after `/opsx:explore` is whatever the user wants to think about. Could be:
+- A vague idea: "real-time collaboration"
+- A specific problem: "the auth system is getting unwieldy"
+- A change name: "add-dark-mode" (to explore in context of that change)
+- A comparison: "postgres vs sqlite for this"
+- Nothing (just enter explore mode)
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**
+```

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+If the user mentioned a specific change name, read its artifacts for context.
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Resolve and read existing artifacts for context**
+   - Run `openspec status --change "<name>" --json`.
+   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
+   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+    | Insight Type               | Where to Capture               |
+    |----------------------------|--------------------------------|
+    | New requirement discovered | `specs/<capability>/spec.md` |
+    | Requirement changed        | `specs/<capability>/spec.md` |
+    | Design decision made       | `design.md`                  |
+    | Scope changed              | `proposal.md`                |
+    | New work identified        | `tasks.md`                   |
+    | Assumption invalidated     | Relevant artifact              |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+Propose a new change - create the change and generate all artifacts in one step.
+
+I'll create a change with artifacts:
+- proposal.md (what & why)
+- design.md (how)
+- tasks.md (implementation steps)
+
+When ready to implement, run /opsx:apply
+
+---
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: The argument after `/opsx:propose` is the change name (kebab-case), OR a description of what the user wants to build.
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` to start implementing."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+description: Sync delta specs from a change to main specs
+---
+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name after `/opsx:sync` (e.g., `/opsx:sync add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Resolve change context**
+
+   Run:
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+
+3. **Find delta specs**
+
+   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+4. **For each delta spec, apply changes to main specs**
+
+   For each repo-local capability delta spec path returned by the CLI:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+5. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+---
+
+Implement tasks from an OpenSpec change.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read every file path listed under `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**

+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+---
+
+Archive a completed change in the experimental workflow.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
+   ```bash
+   mkdir -p "<planningHome.changesDir>/archive"
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move `changeRoot` to the archive directory
+
+   ```bash
+   mv "<changeRoot>" "<planningHome.changesDir>/archive/YYYY-MM-DD-<name>"
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Whether specs were synced (if applicable)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
+
+All artifacts complete. All tasks complete.
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use openspec-sync-specs approach (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+description: Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.

+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.5.0"
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Resolve and read existing artifacts for context**
+   - Run `openspec status --change "<name>" --json`.
+   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
+   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+    | Insight Type               | Where to Capture               |
+    |----------------------------|--------------------------------|
+    | New requirement discovered | `specs/<capability>/spec.md` |
+    | Requirement changed        | `specs/<capability>/spec.md` |
+    | Design decision made       | `design.md`                  |
+    | Scope changed              | `proposal.md`                |
+    | New work identified        | `tasks.md`                   |
+    | Assumption invalidated     | Relevant artifact              |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---

+

+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When it feels like things are crystallizing, you might summarize:
+
+```
+## What We Figured Out
+
+**The problem**: [crystallized understanding]
+
+**The approach**: [if one emerged]
+
+**Open questions**: [if any remain]
+
+**Next steps** (if ready):
+- Create a change proposal
+- Keep exploring: just keep talking
+```
+
+But this summary is optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+Propose a new change - create the change and generate all artifacts in one step.
+
+I'll create a change with artifacts:
+- proposal.md (what & why)
+- design.md (how)
+- tasks.md (implementation steps)
+
+When ready to implement, run /opsx:apply
+
+---
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`).

+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Resolve change context**
+
+   Run:
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+
+3. **Find delta specs**
+
+   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+4. **For each delta spec, apply changes to main specs**
+
+   For each repo-local capability delta spec path returned by the CLI:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+5. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+description: Implement tasks from an OpenSpec change (Experimental)
+---
+
+Implement tasks from an OpenSpec change.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx:continue`
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read every file path listed under `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! You can archive this change with `/opsx:archive`.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name after `/opsx:archive` (e.g., `/opsx:archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
+   ```bash
+   mkdir -p "<planningHome.changesDir>/archive"
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move `changeRoot` to the archive directory
+
+   ```bash
+   mv "<changeRoot>" "<planningHome.changesDir>/archive/YYYY-MM-DD-<name>"
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Spec sync status (synced / sync skipped / no delta specs)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success (No Delta Specs)**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
+**Specs:** No delta specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success With Warnings**
+
+```
+## Archive Complete (with warnings)
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
+**Specs:** Sync skipped (user chose to skip)
+
+**Warnings:**
+- Archived with 2 incomplete artifacts
+- Archived with 3 incomplete tasks
+- Delta spec sync was skipped (user chose to skip)
+
+Review the archive if this was not intentional.
+```
+
+**Output On Error (Archive Exists)**
+
+```
+## Archive Failed
+
+**Change:** <change-name>
+**Target:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
+
+Target archive directory already exists.
+
+**Options:**
+1. Rename the existing archive
+2. Delete the existing archive if it's a duplicate
+3. Wait until a different date to archive
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use the Skill tool to invoke `openspec-sync-specs` (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+description: Enter explore mode - think through ideas, investigate problems, clarify requirements
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: The argument after `/opsx:explore` is whatever the user wants to think about. Could be:
+- A vague idea: "real-time collaboration"
+- A specific problem: "the auth system is getting unwieldy"
+- A change name: "add-dark-mode" (to explore in context of that change)
+- A comparison: "postgres vs sqlite for this"
+- Nothing (just enter explore mode)
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+---
+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+If the user mentioned a specific change name, read its artifacts for context.
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Resolve and read existing artifacts for context**
+   - Run `openspec status --change "<name>" --json`.
+   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
+   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+    | Insight Type               | Where to Capture               |
+    |----------------------------|--------------------------------|
+    | New requirement discovered | `specs/<capability>/spec.md` |
+    | Requirement changed        | `specs/<capability>/spec.md` |
+    | Design decision made       | `design.md`                  |
+    | Scope changed              | `proposal.md`                |
+    | New work identified        | `tasks.md`                   |
+    | Assumption invalidated     | Relevant artifact              |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+- tasks.md (implementation steps)

+When ready to implement, run /opsx:apply

+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: The argument after `/opsx:propose` is the change name (kebab-case), OR a description of what the user wants to build.
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` to start implementing."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+description: Sync delta specs from a change to main specs
+---
+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name after `/opsx:sync` (e.g., `/opsx:sync add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Resolve change context**
+
+   Run:
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+
+3. **Find delta specs**
+
+   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+4. **For each delta spec, apply changes to main specs**
+
+   For each repo-local capability delta spec path returned by the CLI:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+5. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+
+Implement tasks from an OpenSpec change.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read every file path listed under `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! Ready to archive this change.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+Archive a completed change in the experimental workflow.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
+   ```bash
+   mkdir -p "<planningHome.changesDir>/archive"
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move `changeRoot` to the archive directory
+
+   ```bash
+   mv "<changeRoot>" "<planningHome.changesDir>/archive/YYYY-MM-DD-<name>"
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Whether specs were synced (if applicable)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
+
+All artifacts complete. All tasks complete.
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use openspec-sync-specs approach (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+description: Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
+license: MIT
+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.5.0"
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Resolve and read existing artifacts for context**
+   - Run `openspec status --change "<name>" --json`.
+   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
+   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+    | Insight Type               | Where to Capture               |
+    |----------------------------|--------------------------------|
+    | New requirement discovered | `specs/<capability>/spec.md` |
+    | Requirement changed        | `specs/<capability>/spec.md` |
+    | Design decision made       | `design.md`                  |
+    | Scope changed              | `proposal.md`                |
+    | New work identified        | `tasks.md`                   |
+    | Assumption invalidated     | Relevant artifact              |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Handling Different Entry Points
+
+**User brings a vague idea:**
+```

+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When it feels like things are crystallizing, you might summarize:
+
+```
+## What We Figured Out
+
+**The problem**: [crystallized understanding]
+
+**The approach**: [if one emerged]
+
+**Open questions**: [if any remain]
+
+**Next steps** (if ready):
+- Create a change proposal
+- Keep exploring: just keep talking
+```
+
+But this summary is optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+Propose a new change - create the change and generate all artifacts in one step.
+
+I'll create a change with artifacts:
+- proposal.md (what & why)
+- design.md (how)
+- tasks.md (implementation steps)
+
+When ready to implement, run /opsx:apply
+
+---
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+name: openspec-sync-specs
+description: Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.
+license: MIT
+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.5.0"
+---
+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Resolve change context**
+
+   Run:
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+
+3. **Find delta specs**
+
+   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+4. **For each delta spec, apply changes to main specs**
+
+   For each repo-local capability delta spec path returned by the CLI:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+5. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+# Plan: Create AGENTS.md for Animius
+
+## Goal
+Create a compact `AGENTS.md` at the repository root that gives future AI agents the high-signal, repo-specific context they need to work effectively.
+
+## Content
+
+### Build & Run Commands
+- Debug build: `./gradlew assembleDebug`
+- Release build: `./gradlew assembleRelease` (requires env vars)
+- Unit tests: `./gradlew test`
+- Single test class: `./gradlew :app:testDebugUnitTest --tests "com.lanlinju.animius.FooTest"`
+- No lint, typecheck, or formatter configured — skip lint/typecheck steps
+- JVM target: 17, AGP 8.11.0, Kotlin 2.2.0
+
+### Secrets & Environment
+- `DANDANPLAY_APP_ID` and `DANDANPLAY_APP_SECRET` read from env vars (not local.properties) at build time into BuildConfig
+- Signing keys (`KEY_STORE_PASSWORD`, `KEY_ALIAS`, `KEY_PASSWORD`) also from env vars
+- Without these env vars, build succeeds but danmaku features are non-functional
+
+### Module Structure
+- `:app` — main application (MVVM + Clean Architecture)
+- `:video-player` — Compose Media3 ExoPlayer wrapper
+- `:download` — download engine (OkHttp, supports M3U8/range)
+- `:danmaku` — Compose danmaku overlay engine
+
+### Architecture Quick Reference
+- Source code under `app/src/main/java/com/lanlinju/animius/`
+- Layers: `data/` → `domain/` → `presentation/`
+- Multi-source anime scraping via `AnimeSource` interface + `SourceHolder` singleton (11 sources, enum `SourceMode`)
+- DI: Hilt with `@HiltAndroidApp`, `@AndroidEntryPoint`, `@HiltViewModel`
+- Navigation: type-safe Compose Navigation with `@Serializable` sealed class routes
+- State: `MutableStateFlow<Resource<T>>` pattern, no MVI
+- Domain model conversions are extension functions on data classes (not separate mapper files)
+
+### Key Conventions
+- Screens: `{Feature}Screen.kt` + `{Feature}ViewModel.kt` in `presentation/screen/{feature}/`
+- DTOs: `*Bean.kt` suffix
+- Entities: `*Entity.kt`, DAOs: `*Dao.kt`
+- Sources: `{Name}Source.kt` in `data/remote/parse/`
+- Images via Coil, JSON via kotlinx.serialization
+- Room schema exported to `app/schemas/` via KSP
+
+### Gotchas
+- No linting/static analysis configured (no detekt, ktlint, lint.xml)
+- No lockfiles — dependency resolution not reproducible
+- Room uses `fallbackToDestructiveMigration()` — schema changes wipe data
+- Release build has R8 minification — keep rules in `app/proguard-rules.pro`
+- `SourceMode` enum kept in ProGuard (serialized to SharedPreferences as string)
+- WebView-based sources (Xifan, Ntdm, Gugufan) need special handling via `WebViewUtil`
+
+### CI
+- GitHub Actions on push to `main`/`feat-compat-tv`, PRs, and tags
+- CI only builds — no tests run in CI
+- Release workflow triggers on `v*` tags
+
+## File to create
+- `E:\Github\Anime\Animius\AGENTS.md`
+
+## Verification
+- Read the created file to confirm content accuracy
+- Verify commands match CI workflow and build.gradle.kts

+
+- Card border颜色统一为#BCC0C8（深色浅色一致）
+- Week页面TopAppBar标题区域改为圆角矩形焦点背景
+- Home页面站源文本移除clickable，不再可聚焦
+- 详情页标签改为非交互Box，不再可聚焦
+```
+
+## 问题
+
+1. **WeekScreen TabRow** (`WeekScreen.kt:165-175`): Material3 `Tab` 指示器是底部线条，聚焦时无圆角矩形背景
+2. **HomeScreen 站源文本** (`HomeScreen.kt:413-427`): 纯 `Text`，无焦点样式，点击无反应
+3. **HomeScreen GridLayoutTabs** (`HomeScreen.kt:224-230`): 自定义 `Tab` 用 `Surface(RoundedCornerShape(11.dp))`，聚焦有背景但非统一风格
+
+## 方案
+
+### 核心思路
+
+Material3 `Tab` 内置 onClick + focus，但指示器是线条不是圆角矩形。用 `Surface(onClick, shape, color)` 包一层即可获得圆角矩形背景 + 内置 focusable，无需单独建组件。
+
+### 1. 修改 WeekScreen (`WeekScreen.kt:165-175`)
+
+**改前:**
+```kotlin
+TabRow(selectedTabIndex = pagerState.currentPage) {
+    TABS.forEachIndexed { index, title ->
+        Tab(text = { Text(text = title) }, ...)
+    }
+}
+```
+
+**改后:**
+```kotlin
+Row(
+    modifier = Modifier.fillMaxWidth().padding(horizontal = 16.dp),
+    horizontalArrangement = Arrangement.spacedBy(8.dp),
+) {
+    TABS.forEachIndexed { index, title ->
+        Surface(
+            onClick = { scope.launch { pagerState.scrollToPage(index) } },
+            shape = RoundedCornerShape(20.dp),
+            color = if (pagerState.currentPage == index)
+                MaterialTheme.colorScheme.primary
+            else Color.Transparent,
+            contentColor = if (pagerState.currentPage == index)
+                MaterialTheme.colorScheme.onPrimary
+            else MaterialTheme.colorScheme.onSurface,
+        ) {
+            Text(
+                text = title,
+                modifier = Modifier.padding(horizontal = 16.dp, vertical = 8.dp),
+            )
+        }
+    }
+}
+```
+
+### 2. 修改 HomeScreen GridLayoutTabs (`HomeScreen.kt:224-230`)
+
+将自定义 `Tab` 的 `RoundedCornerShape(11.dp)` 改为 `RoundedCornerShape(20.dp)` 统一风格。
+
+### 3. 修改 HomeScreen 站源选择器 (`HomeScreen.kt:413-427`)
+
+将纯 `Text` 改为 `Surface(onClick)` + `DropdownMenu`，点击弹出站源列表。
+
+## 修改文件
+
+| 文件 | 改动 |
+|------|------|
+| `app/.../screen/week/WeekScreen.kt:165-175` | `TabRow` → `Row` + `Surface` |
+| `app/.../screen/home/HomeScreen.kt:224-230` | `RoundedCornerShape(11.dp)` → `20.dp` |
+| `app/.../screen/home/HomeScreen.kt:266-289` | 自定义 `Tab` 的 shape 统一 |
+| `app/.../screen/home/HomeScreen.kt:413-427` | 站源 `Text` → `Surface` + `DropdownMenu` |
+
+## 验证
+
+1. `./gradlew assembleDebug` 编译通过
+2. D-pad 测试：
+   - Week 页面 Tab 聚焦显示圆角矩形背景
+   - Home 页面 Tab 聚焦显示圆角矩形背景
+   - Home 站源可聚焦，点击弹出列表

+
+Implement tasks from an OpenSpec change.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name (e.g., `/opsx-apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx-apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx-continue`
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read every file path listed under `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! You can archive this change with `/opsx-archive`.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name after `/opsx-archive` (e.g., `/opsx-archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Prompt user for confirmation to continue
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
+   ```bash
+   mkdir -p "<planningHome.changesDir>/archive"
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move `changeRoot` to the archive directory
+
+   ```bash
+   mv "<changeRoot>" "<planningHome.changesDir>/archive/YYYY-MM-DD-<name>"
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Spec sync status (synced / sync skipped / no delta specs)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success (No Delta Specs)**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
+**Specs:** No delta specs
+
+All artifacts complete. All tasks complete.
+```
+
+**Output On Success With Warnings**
+
+```
+## Archive Complete (with warnings)
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
+**Specs:** Sync skipped (user chose to skip)
+
+**Warnings:**
+- Archived with 2 incomplete artifacts
+- Archived with 3 incomplete tasks
+- Delta spec sync was skipped (user chose to skip)
+
+Review the archive if this was not intentional.
+```
+
+**Output On Error (Archive Exists)**
+
+```
+## Archive Failed
+
+**Change:** <change-name>
+**Target:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
+
+Target archive directory already exists.
+
+**Options:**
+1. Rename the existing archive
+2. Delete the existing archive if it's a duplicate
+3. Wait until a different date to archive
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use the Skill tool to invoke `openspec-sync-specs` (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+description: Enter explore mode - think through ideas, investigate problems, clarify requirements
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: The argument after `/opsx-explore` is whatever the user wants to think about. Could be:
+- A vague idea: "real-time collaboration"
+- A specific problem: "the auth system is getting unwieldy"
+- A change name: "add-dark-mode" (to explore in context of that change)
+- A comparison: "postgres vs sqlite for this"
+- Nothing (just enter explore mode)
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**
+```

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+If the user mentioned a specific change name, read its artifacts for context.
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Resolve and read existing artifacts for context**
+   - Run `openspec status --change "<name>" --json`.
+   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
+   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+    | Insight Type               | Where to Capture               |
+    |----------------------------|--------------------------------|
+    | New requirement discovered | `specs/<capability>/spec.md` |
+    | Requirement changed        | `specs/<capability>/spec.md` |
+    | Design decision made       | `design.md`                  |
+    | Scope changed              | `proposal.md`                |
+    | New work identified        | `tasks.md`                   |
+    | Assumption invalidated     | Relevant artifact              |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---
+
+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: The argument after `/opsx-propose` is the change name (kebab-case), OR a description of what the user wants to build.
+
+**Steps**
+
+1. **If no input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx-apply` to start implementing."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.

+   ```bash
+   openspec status --change "<name>" --json
+   ```
+
+3. **Find delta specs**
+
+   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+4. **For each delta spec, apply changes to main specs**
+
+   For each repo-local capability delta spec path returned by the CLI:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+5. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+# Fix: EpisodeListControl click not responding
+
+## Problem
+EpisodeListControl "reverse list" and "more episodes" buttons stopped responding to clicks after adding background + focus inverse color effect.
+
+## Root cause
+The modifier chain used `.let { mod -> if (isAndroidTV) mod.onFocusChanged{}.focusable() else mod }` before `.clickable()`. This appears to interfere with `clickable`'s internal focus/click handling — `clickable` already adds `focusable()` internally, and the explicit one before it may conflict.
+
+## Fix
+Replace the conditional `.let{}` with direct `.onFocusChanged{}`:
+- Remove the `.let{}` block
+- Remove the explicit `.focusable()` (redundant — `clickable` handles it)
+- Use `.onFocusChanged {}` directly at the same position (safe observer, no side effects on phone/TV)
+- Keep the `isAndroidTV` guard inside the lambda to only update state on TV
+
+## Modified modifier chain (phone and TV same):
+`clip -> background -> onFocusChanged -> clickable -> padding`
+
+## Build & Install
+- `.\gradlew assembleDebug`
+- `adb install -r app/build/outputs/apk/debug/Animius-v1.3.5-debug.apk`

+---
+
+Implement tasks from an OpenSpec change.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **Select the change**
+
+   If a name is provided, use it. Otherwise:
+   - Infer from conversation context if the user mentioned a change
+   - Auto-select if only one active change exists
+   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
+
+   Always announce: "Using change: <name>" and how to override (e.g., `/opsx-apply <other>`).
+
+2. **Check status to understand the schema**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used (e.g., "spec-driven")
+   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
+   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
+
+3. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
+   - If `state: "all_done"`: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+4. **Read context files**
+
+   Read every file path listed under `contextFiles` from the apply instructions output.
+   The files depend on the schema being used:
+   - **spec-driven**: proposal, specs, design, tasks
+   - Other schemas: follow the contextFiles from CLI output
+
+5. **Show current progress**
+
+   Display:
+   - Schema being used
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+6. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+7. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+
+**Output During Implementation**
+
+```
+## Implementing: <change-name> (schema: <schema-name>)
+
+Working on task 3/7: <task description>
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: <task description>
+[...implementation happening...]
+✓ Task complete
+```
+
+**Output On Completion**
+
+```
+## Implementation Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Task 1
+- [x] Task 2
+...
+
+All tasks complete! Ready to archive this change.
+```
+
+**Output On Pause (Issue Encountered)**
+
+```
+## Implementation Paused
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+<description of the issue>
+
+**Options:**
+1. <option 1>
+2. <option 2>
+3. Other approach
+
+What would you like to do?
+```
+
+**Guardrails**
+- Keep going through tasks until done or blocked
+- Always read context files before starting (from the apply instructions output)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+- Use contextFiles from CLI output, don't assume specific file names
+
+**Fluid Workflow Integration**
+
+This skill supports the "actions on a change" model:
+
+- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
+- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

+
+Archive a completed change in the experimental workflow.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show only active changes (not already archived).
+   Include the schema used for each change if available.
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Check artifact completion status**
+
+   Run `openspec status --change "<name>" --json` to check artifact completion.
+
+   Parse the JSON to understand:
+   - `schemaName`: The workflow being used
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
+   - `artifacts`: List of artifacts with their status (`done` or other)
+
+   **If any artifacts are not `done`:**
+   - Display warning listing incomplete artifacts
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+3. **Check task completion status**
+
+   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
+
+   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
+
+   **If incomplete tasks found:**
+   - Display warning showing count of incomplete tasks
+   - Use **AskUserQuestion tool** to confirm user wants to proceed
+   - Proceed if user confirms
+
+   **If no tasks file exists:** Proceed without task-related warning.
+
+4. **Assess delta spec sync state**
+
+   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
+
+   **If delta specs exist:**
+   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
+   - Determine what changes would be applied (adds, modifications, removals, renames)
+   - Show a combined summary before prompting
+
+   **Prompt options:**
+   - If changes needed: "Sync now (recommended)", "Archive without syncing"
+   - If already synced: "Archive now", "Sync anyway", "Cancel"
+
+   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
+
+5. **Perform the archive**
+
+   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
+   ```bash
+   mkdir -p "<planningHome.changesDir>/archive"
+   ```
+
+   Generate target name using current date: `YYYY-MM-DD-<change-name>`
+
+   **Check if target already exists:**
+   - If yes: Fail with error, suggest renaming existing archive or using different date
+   - If no: Move `changeRoot` to the archive directory
+
+   ```bash
+   mv "<changeRoot>" "<planningHome.changesDir>/archive/YYYY-MM-DD-<name>"
+   ```
+
+6. **Display summary**
+
+   Show archive completion summary including:
+   - Change name
+   - Schema that was used
+   - Archive location
+   - Whether specs were synced (if applicable)
+   - Note about any warnings (incomplete artifacts/tasks)
+
+**Output On Success**
+
+```
+## Archive Complete
+
+**Change:** <change-name>
+**Schema:** <schema-name>
+**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
+**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
+
+All artifacts complete. All tasks complete.
+```
+
+**Guardrails**
+- Always prompt for change selection if not provided
+- Use artifact graph (openspec status --json) for completion checking
+- Don't block archive on warnings - just inform and confirm
+- Preserve .openspec.yaml when moving to archive (it moves with the directory)
+- Show clear summary of what happened
+- If sync is requested, use openspec-sync-specs approach (agent-driven)
+- If delta specs exist, always run the sync assessment and show the combined summary before prompting

+  version: "1.0"
+  generatedBy: "1.5.0"
+---
+
+Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
+
+**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
+
+**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+---
+
+## The Stance
+
+- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
+- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
+- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
+- **Adaptive** - Follow interesting threads, pivot when new information emerges
+- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
+- **Grounded** - Explore the actual codebase when relevant, don't just theorize
+
+---
+
+## What You Might Do
+
+Depending on what the user brings, you might:
+
+**Explore the problem space**
+- Ask clarifying questions that emerge from what they said
+- Challenge assumptions
+- Reframe the problem
+- Find analogies
+
+**Investigate the codebase**
+- Map existing architecture relevant to the discussion
+- Find integration points
+- Identify patterns already in use
+- Surface hidden complexity
+
+**Compare options**
+- Brainstorm multiple approaches
+- Build comparison tables
+- Sketch tradeoffs
+- Recommend a path (if asked)
+
+**Visualize**

+
+## OpenSpec Awareness
+
+You have full context of the OpenSpec system. Use it naturally, don't force it.
+
+### Check for context
+
+At the start, quickly check what exists:
+```bash
+openspec list --json
+```
+
+This tells you:
+- If there are active changes
+- Their names, schemas, and status
+- What the user might be working on
+
+### When no change exists
+
+Think freely. When insights crystallize, you might offer:
+
+- "This feels solid enough to start a change. Want me to create a proposal?"
+- Or keep exploring - no pressure to formalize
+
+### When a change exists
+
+If the user mentions a change or you detect one is relevant:
+
+1. **Resolve and read existing artifacts for context**
+   - Run `openspec status --change "<name>" --json`.
+   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
+   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
+
+2. **Reference them naturally in conversation**
+   - "Your design mentions using Redis, but we just realized SQLite fits better..."
+   - "The proposal scopes this to premium users, but we're now thinking everyone..."
+
+3. **Offer to capture when decisions are made**
+
+    | Insight Type               | Where to Capture               |
+    |----------------------------|--------------------------------|
+    | New requirement discovered | `specs/<capability>/spec.md` |
+    | Requirement changed        | `specs/<capability>/spec.md` |
+    | Design decision made       | `design.md`                  |
+    | Scope changed              | `proposal.md`                |
+    | New work identified        | `tasks.md`                   |
+    | Assumption invalidated     | Relevant artifact              |
+
+   Example offers:
+   - "That's a design decision. Capture it in design.md?"
+   - "This is a new requirement. Add it to specs?"
+   - "This changes scope. Update the proposal?"
+
+4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
+
+---
+
+## What You Don't Have To Do
+
+- Follow a script
+- Ask the same questions every time
+- Produce a specific artifact
+- Reach a conclusion
+- Stay on topic if a tangent is valuable
+- Be brief (this is thinking time)
+
+---

+## Ending Discovery
+
+There's no required ending. Discovery might:
+
+- **Flow into a proposal**: "Ready to start? I can create a change proposal."
+- **Result in artifact updates**: "Updated design.md with these decisions"
+- **Just provide clarity**: User has what they need, moves on
+- **Continue later**: "We can pick this up anytime"
+
+When it feels like things are crystallizing, you might summarize:
+
+```
+## What We Figured Out
+
+**The problem**: [crystallized understanding]
+
+**The approach**: [if one emerged]
+
+**Open questions**: [if any remain]
+
+**Next steps** (if ready):
+- Create a change proposal
+- Keep exploring: just keep talking
+```
+
+But this summary is optional. Sometimes the thinking IS the value.
+
+---
+
+## Guardrails
+
+- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
+- **Don't fake understanding** - If something is unclear, dig deeper
+- **Don't rush** - Discovery is thinking time, not task time
+- **Don't force structure** - Let patterns emerge naturally
+- **Don't auto-capture** - Offer to save insights, don't just do it
+- **Do visualize** - A good diagram is worth many paragraphs
+- **Do explore the codebase** - Ground discussions in reality
+- **Do question assumptions** - Including the user's and your own

+Propose a new change - create the change and generate all artifacts in one step.
+
+I'll create a change with artifacts:
+- proposal.md (what & why)
+- design.md (how)
+- tasks.md (implementation steps)
+
+When ready to implement, run /opsx-apply
+
+---
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
+
+**Steps**
+
+1. **If no clear input provided, ask what they want to build**
+
+   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
+   > "What change do you want to work on? Describe what you want to build or fix."
+
+   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
+
+   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
+
+2. **Create the change directory**
+   ```bash
+   openspec new change "<name>"
+   ```
+   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
+
+3. **Get the artifact build order**
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+   Parse the JSON to get:
+   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
+   - `artifacts`: list of all artifacts with their status and dependencies
+   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
+
+4. **Create artifacts in sequence until apply-ready**
+
+   Use the **TodoWrite tool** to track progress through the artifacts.
+
+   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
+
+   a. **For each artifact that is `ready` (dependencies satisfied)**:
+      - Get instructions:
+        ```bash
+        openspec instructions <artifact-id> --change "<name>" --json
+        ```
+      - The instructions JSON includes:
+        - `context`: Project background (constraints for you - do NOT include in output)
+        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
+        - `template`: The structure to use for your output file
+        - `instruction`: Schema-specific guidance for this artifact type
+        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
+        - `dependencies`: Completed artifacts to read for context
+      - Read any completed dependency files for context
+      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
+      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
+      - Show brief progress: "Created <artifact-id>"
+
+   b. **Continue until all `applyRequires` artifacts are complete**
+      - After creating each artifact, re-run `openspec status --change "<name>" --json`
+      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
+      - Stop when all `applyRequires` artifacts are done
+
+   c. **If an artifact requires user input** (unclear context):
+      - Use **AskUserQuestion tool** to clarify
+      - Then continue with creation
+
+5. **Show final status**
+   ```bash
+   openspec status --change "<name>"
+   ```
+
+**Output**
+
+After completing all artifacts, summarize:
+- Change name and location
+- List of artifacts created with brief descriptions
+- What's ready: "All artifacts created! Ready for implementation."
+- Prompt: "Run `/opsx-apply` or ask me to implement to start working on the tasks."
+
+**Artifact Creation Guidelines**
+
+- Follow the `instruction` field from `openspec instructions` for each artifact type
+- The schema defines what each artifact should contain - follow it
+- Read dependency artifacts for context before creating new ones
+- Use `template` as the structure for your output file - fill in its sections
+- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
+  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
+  - These guide what you write, but should never appear in the output
+
+**Guardrails**
+- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
+- Always read dependency artifacts before creating a new one
+- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
+- If a change with that name already exists, ask if user wants to continue it or create a new one
+- Verify each artifact file exists after writing before proceeding to next

+name: openspec-sync-specs
+description: Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.
+license: MIT
+compatibility: Requires openspec CLI.
+metadata:
+  author: openspec
+  version: "1.0"
+  generatedBy: "1.5.0"
+---
+
+Sync delta specs from a change to main specs.
+
+This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
+
+**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
+
+**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
+
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
+
+   Show changes that have delta specs (under `specs/` directory).
+
+   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
+
+2. **Resolve change context**
+
+   Run:
+   ```bash
+   openspec status --change "<name>" --json
+   ```
+
+3. **Find delta specs**
+
+   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
+
+   Each delta spec file contains sections like:
+   - `## ADDED Requirements` - New requirements to add
+   - `## MODIFIED Requirements` - Changes to existing requirements
+   - `## REMOVED Requirements` - Requirements to remove
+   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
+
+   If no delta specs found, inform user and stop.
+
+4. **For each delta spec, apply changes to main specs**
+
+   For each repo-local capability delta spec path returned by the CLI:
+
+   a. **Read the delta spec** to understand the intended changes
+
+   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
+
+   c. **Apply changes intelligently**:
+
+      **ADDED Requirements:**
+      - If requirement doesn't exist in main spec → add it
+      - If requirement already exists → update it to match (treat as implicit MODIFIED)
+
+      **MODIFIED Requirements:**
+      - Find the requirement in main spec
+      - Apply the changes - this can be:
+        - Adding new scenarios (don't need to copy existing ones)
+        - Modifying existing scenarios
+        - Changing the requirement description
+      - Preserve scenarios/content not mentioned in the delta
+
+      **REMOVED Requirements:**
+      - Remove the entire requirement block from main spec
+
+      **RENAMED Requirements:**
+      - Find the FROM requirement, rename to TO
+
+   d. **Create new main spec** if capability doesn't exist yet:
+      - Create `openspec/specs/<capability>/spec.md`
+      - Add Purpose section (can be brief, mark as TBD)
+      - Add Requirements section with the ADDED requirements
+
+5. **Show summary**
+
+   After applying all changes, summarize:
+   - Which capabilities were updated
+   - What changes were made (requirements added/modified/removed/renamed)
+
+**Delta Spec Format Reference**
+
+```markdown
+## ADDED Requirements
+
+### Requirement: New Feature
+The system SHALL do something new.
+
+#### Scenario: Basic case
+- **WHEN** user does X
+- **THEN** system does Y
+
+## MODIFIED Requirements
+
+### Requirement: Existing Feature
+#### Scenario: New scenario to add
+- **WHEN** user does A
+- **THEN** system does B
+
+## REMOVED Requirements
+
+### Requirement: Deprecated Feature
+
+## RENAMED Requirements
+
+- FROM: `### Requirement: Old Name`
+- TO: `### Requirement: New Name`
+```
+
+**Key Principle: Intelligent Merging**
+
+Unlike programmatic merging, you can apply **partial updates**:
+- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
+- The delta represents *intent*, not a wholesale replacement
+- Use your judgment to merge changes sensibly
+
+**Output On Success**
+
+```
+## Specs Synced: <change-name>
+
+Updated main specs:
+
+**<capability-1>**:
+- Added requirement: "New Feature"
+- Modified requirement: "Existing Feature" (added 1 scenario)
+
+**<capability-2>**:
+- Created new spec file
+- Added requirement: "Another Feature"
+
+Main specs are now updated. The change remains active - archive when implementation is complete.
+```
+
+**Guardrails**
+- Read both delta and main specs before making changes
+- Preserve existing content not mentioned in delta
+- If something is unclear, ask for clarification
+- Show what you're changing as you go
+- The operation should be idempotent - running twice should give same result

+
+## Project overview
+
+Animius is a multi-source Android anime streaming app. Kotlin/Jetpack Compose, MVVM + Clean Architecture. 4 Gradle modules.
+
+## Module structure
+
+| Module | Package | Purpose | Compose? |
+|---|---|---|---|
+| `:app` | `com.lanlinju.animius` | Main app — UI, data, DI, all features | Yes |
+| `:video-player` | `com.lanlinju.videoplayer` | ExoPlayer/Media3 video player wrapper | Yes |
+| `:download` | `com.lanlinju.download` | HTTP/M3U8 download engine (OkHttp + Retrofit) | No |
+| `:danmaku` | `com.anime.danmaku` | Danmaku (bullet comment) rendering engine | Yes |
+
+Dependency graph: `app` → `video-player`, `app` → `download`, `app` → `danmaku`. No cross-deps between library modules.
+
+## Build
+
+```bash
+./gradlew assembleDebug          # debug APK
+./gradlew assembleRelease        # release APK (needs signing env vars)
+```
+
+- **Gradle 8.14**, AGP 8.11.0, Kotlin 2.2.0, JVM target 17
+- Version catalog: `gradle/libs.versions.toml` (single source of truth for versions)
+- compileSdk 36, minSdk 26, targetSdk 36
+
+## Tests
+
+```bash
+./gradlew test                       # all JVM unit tests
+./gradlew :app:test                  # app module unit tests only
+./gradlew :danmaku:test              # danmaku module unit tests only
+./gradlew connectedAndroidTest       # instrumented tests (needs device/emulator)
+```
+
+- JUnit 4 throughout. Some tests hit real network (source parsers, Dandanplay client).
+- DAO tests use Room in-memory DB (instrumented only).
+- **Tests are NOT run in CI** — CI only runs `assembleDebug`/`assembleRelease`.
+- No lint/format/static analysis tools configured (no detekt, ktlint, spotless, or .editorconfig).
+
+## Code generation
+
+KSP is used for:
+- **Hilt** (`com.google.dagger:hilt-compiler`) — DI boilerplate
+- **Room** (`androidx.room:room-compiler`) — DAO implementations
+
+Room schemas are exported to `app/schemas/` (required for migration testing).
+
+## Secrets / env vars
+
+Build-time environment variables (no .env files in repo):
+- `DANDANPLAY_APP_ID` / `DANDANPLAY_APP_SECRET` — DanDanPlay danmaku API credentials (injected into `BuildConfig`)
+- `KEY_STORE_PASSWORD` / `KEY_ALIAS` / `KEY_PASSWORD` — APK signing (release only)
+
+Debug builds work without any env vars set.
+
+## Architecture quick reference

+```
+
+**Source system**: 11 anime site scrapers implement `AnimeSource` interface (`getHomeData`, `getAnimeDetail`, `getVideoData`, `getSearchData`, `getWeekData`). `SourceHolder` singleton manages active source at runtime.
+
+**Navigation**: Type-safe sealed `Screen` class with Kotlinx Serialization routes in `presentation/navigation/`.
+
+**Crash handler**: Runs in separate `:error_handler` process via `CrashActivity`. Global uncaught exception handler in `MainActivity`.
+
+## Key gotchas
+
+- Source parsers use Jsoup to scrape live websites — they break when sites change markup. Tests for these exist but rely on local HTML fixtures or real network calls.
+- `AnimeApplication.getInstance()` exposes a static context — used by `SourceHolder` and `Preferences` outside DI.
+- Release builds have `isMinifyEnabled = true` + `isShrinkResources = true` with ProGuard. `SourceMode` enum is kept explicitly in `proguard-rules.pro`.
+- `download` module is pure Kotlin (no Compose). `video-player` and `danmaku` are Compose libraries.

+# TV Remote Control Fixes Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use compose:subagent (recommended) or compose:execute to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Fix D-pad behavior, improve focus styles, and align with JetStream/TvMaterialCatalog patterns.
+
+**Architecture:** Modify video-player module's Slider and VideoPlayerControl for focus handling. Update app module's VideoPlayerScreen for D-pad logic. Update detail/search screens for focus visibility.
+
+**Tech Stack:** Jetpack Compose, Material3
+
+---
+
+### Task 1: Fix D-pad left/right behavior in defaultRemoteControlHandler
+
+**Covers:** [S1]
+
+**Files:**
+- Modify: `app/src/main/java/com/lanlinju/animius/presentation/screen/videoplayer/VideoPlayerScreen.kt:390-434`
+
+- [ ] **Step 1: Update defaultRemoteControlHandler signature**
+
+Add `onSliderFocusRequest` parameter:
+
+```kotlin
+private fun Modifier.defaultRemoteControlHandler(
+    playerState: VideoPlayerState,
+    onNextClick: () -> Unit = {},
+    onSliderFocusRequest: () -> Unit = {},
+) = onKeyEvent { keyEvent: KeyEvent ->

+# TV Remote Control Support Implementation Plan
+
+> [!NOTE]
+> This document may not reflect the current implementation.
+> See the final report for up-to-date state:
+> [Final Report](../reports/tv-remote-support.md)
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use compose:subagent (recommended) or compose:execute to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add D-pad remote control support to the video player and improve focus highlight visibility across the app for Android TV.
+
+**Architecture:** Add focusable modifiers + focus border visual feedback to all interactive elements in `VideoPlayerControl`. Enhance `defaultRemoteControlHandler` in `VideoPlayScreen` for full D-pad navigation. Extract a reusable `tvFocusBorder` modifier. Adjust existing focus border styles in other screens.
+
+**Tech Stack:** Jetpack Compose, Media3 ExoPlayer, standard Material3 (no TV Material3 dependency)
+
+---
+

+# TV Remote Control Support — Final Report
+
+## What Was Built
+
+Added D-pad remote control support to the video player and improved focus highlight visibility across the app for Android TV. The video player now supports full D-pad navigation: left/right to seek, up to show controls, down for next episode, center/enter to play/pause. All player control buttons (play/pause, next, danmaku, speed, resize, episode selector) display a 2dp primary-color border when focused. The progress slider supports D-pad left/right seeking with visual feedback. On Android TV, focus is automatically applied to the first control button when the control overlay appears. Other screens (anime detail episode buttons, search result items) also received improved focus border visibility.
+
+## Architecture
+
+### Files Modified
+
+| File | Changes |
+|------|---------|
+| `video-player/.../VideoPlayerControl.kt` | Added `tvFocusBorder` modifier, wired into `AdaptiveIconButton` and `AdaptiveTextButton`, added `modifier` parameter to `VideoPlayerControl` |
+| `video-player/.../component/Slider.kt` | Added focusable, focus border, D-pad key handling (left/right seek, center confirm) |
+| `app/.../videoplayer/VideoPlayerScreen.kt` | Enhanced `defaultRemoteControlHandler` (KeyUp instead of KeyDown), added auto-focus on TV via `FocusRequester` + `LaunchedEffect` |
+| `app/.../detail/AnimeDetailScreen.kt` | Added focus border to episode buttons |
+| `app/.../search/SearchScreen.kt` | Added focus border to search result items |
+
+### Key Components
+
+- **`tvFocusBorder` modifier** — Reusable Compose modifier that shows a 2dp primary-color `RoundedCornerShape(8.dp)` border when an element has D-pad focus. Uses `MutableInteractionSource.collectIsFocusedAsState()` for idiomatic focus tracking.
+- **`defaultRemoteControlHandler`** — `Modifier.onKeyEvent` extension mapping D-pad keys to player actions. Consumes events on `KeyUp` (not `KeyDown`) to prevent repeat-firing.
+- **Auto-focus on TV** — `LaunchedEffect` watches `isControlUiVisible` and requests focus on the first control button via `FocusRequester` when controls appear on Android TV.
+
+### Design Decisions
+
+- **Plain Material3 + manual focus** (not TV Material3) — Minimizes migration risk, phone and TV share the same UI code with `isAndroidTV()` checks for focus behavior only.
+- **KeyUp consumption** — Prevents D-pad repeat-firing that caused unintended rapid seek/play-pause toggling.
+- **2dp primary border** — Visible but unobtrusive; uses `MaterialTheme.colorScheme.primary` for consistency with the app theme.
+
+## Verification

+# Focus Border & Long Press Spec
+
+## MediaSmall Focus Border
+
+### Component
+`MediaSmall` in `app/src/main/java/com/lanlinju/animius/presentation/component/MediaSmall.kt`
+
+### Behavior
+When a `MediaSmall` card receives D-pad focus, a **3dp white rounded-corner border** appears around the card. When focus leaves, the border disappears (0dp/transparent).
+
+### Implementation
+```
+Card(onClick) → modifier.onFocusChanged → modifier.border(Color.White, 3dp, cardShape)
+```
+
+- `Card(onClick)` makes the card focusable by default (no extra `focusable()` needed)
+- `onFocusChanged` tracks `isFocused` state
+- `border` conditionally renders 3dp white border when focused, 0dp transparent when not
+- Card retains default Material3 elevation, ripple, and dimming on focus
+
+### Key discovery
+`LazyRow` and `LazyVerticalGrid` do NOT forward D-pad focus to individual items by default. Must add `Modifier.focusGroup()` to the container:
+
+- `MediaSmallRow` → `LazyRow(modifier = Modifier.focusGroup())`
+- HomeScreen `LazyVerticalGrid` → `.focusGroup()`
+- FavouriteScreen `LazyVerticalGrid` → `.focusGroup()`
+
+### What doesn't work (abandoned approaches)
+- **Box wrapper + border**: Card's internal focus indicator overrides outer border
+- **`combinedClickable` + `focusable()`**: `combinedClickable` steals focus, `onFocusChanged` never fires
+- **`clickable(indication = null)` + `focusable()`**: Card never receives focus
+- **ClassicCard (TV Material3)**: Not clickable on physical phone devices
+- **Color inversion for dark theme**: Makes cards darker, not brighter
+
+---
+
+## Favourite Screen Long Press Menu
+
+### Behavior
+Long press on a favourite card shows a delete confirmation menu. Short press navigates to detail page.
+
+| Input | Short Press | Long Press |
+|-------|-------------|------------|
+| Touch | Navigate to detail | Show delete menu (no navigation) |
+| D-pad (Center button) | Navigate to detail | Show delete menu (no navigation) |
+
+### Implementation
+Long press is handled in `FavouriteScreen` (NOT in `MediaSmall`), using two independent mechanisms:
+
+#### Touch long press
+```
+Modifier.pointerInput → awaitEachGesture → awaitFirstDown → track touchPressed state
+LaunchedEffect(touchPressed) → delay(longPressTimeout) → show menu
+```
+
+- `pointerInput` detects finger down/up via `awaitEachGesture`
+- Sets `touchPressed = true` on down, `false` on up
+- `LaunchedEffect(touchPressed)` starts a timer when finger goes down
+- If finger lifts before timeout → `touchPressed = false` → effect cancelled (short press)
+- If timeout fires → `longPressConsumed = true` → show menu
+
+#### D-pad long press
+```
+Modifier.onPreviewKeyEvent → Center KeyDown → Handler.postDelayed(longPressTimeout) → show menu
+                         → Center KeyUp → Handler.removeCallbacksAndMessages → manual onClick
+```
+
+- `onPreviewKeyEvent` consumes Center key events (returns `true`), preventing Card's internal click handling
+- KeyDown starts a `Handler.postDelayed` timer
+- KeyUp cancels the timer. If timer hadn't fired (short press), manually calls `onNavigateToAnimeDetail()`
+- `DisposableEffect(Unit)` cleans up Handler when composable leaves the tree
+
+#### Shared flag
+```
+var longPressConsumed by remember { mutableStateOf(false) }
+```
+
+- Set to `true` when long press is detected (by either mechanism)
+- Card's `onClick` checks: `if (!longPressConsumed) { navigate }`
+- Reset to `false` after check (prevents stale state from blocking future clicks)
+
+### Files
+- `app/.../favourite/FavouriteScreen.kt` — all long press logic lives here
+- `app/.../component/MediaSmall.kt` — no long press logic, pure Card + border + focus
+
+### Why long press is NOT in MediaSmall
+MediaSmall is shared across Home, Favourite, Detail, and Search screens. Only Favourite needs long press. Putting it in MediaSmall would:
+- Add `onLongClick` parameter to all callers
+- Risk Handler/LaunchedEffect leaks across screen navigations
+- Couple a UI component with screen-specific behavior
+
+### Why `onPreviewKeyEvent` consumes D-pad events
+`Card(onClick)` internally handles Center key as a click. Without consuming, both Card's onClick AND the long press timer would fire. Consuming lets us control the flow: short press → manual onClick, long press → menu only.
+
+### What doesn't work (abandoned approaches)
+- **`detectTapGestures` on Box wrapper**: Consumes events, breaks Card's onClick
+- **`combinedClickable` on Box wrapper**: Steals focus from inner Card, border disappears
+- **`pointerInput` + `consume()` after long press**: Breaks `awaitEachGesture` loop, all subsequent gestures fail
+- **LaunchedEffect for D-pad**: Timing inconsistency with key events vs coroutine scheduling
+- **Handler without DisposableEffect**: Leaked callbacks fire after screen navigation

+# TV Focus Inverse Color — Implementation Spec
+
+## Problem
+
+On Android TV, buttons in the anime detail page used a default dimming effect when focused via remote control, making it hard to distinguish the focused element. The goal was to replace this with a clear inverse-color effect (like Compose for TV buttons): focused button gets `primary` background with `onPrimary` content.
+
+## Affected Components
+
+| Component | Composable | Button type |
+|---|---|---|
+| Back button | `TopAppBar.navigationIcon` | `IconButton` |
+| More menu | `TopAppBar.actions` | `IconButton` |
+| Favorite heart | `FavouriteIcon` | `IconButton` |
+| Episode pills | `AnimeEpisodes` | `FilledTonalButton` |
+| Reverse list | `EpisodeListControl` | `Text` → wrapped in `Box` |
+| More episodes | `EpisodeListControl` | `Row` |
+| Channel selector | `EpisodeListControl` | `Text` → wrapped in `Box` |
+| Episode chips (bottom sheet) | `EpisodeBottomSheet` | `SuggestionChip` |
+
+## Implementation Patterns
+
+### Pattern A: Components with `interactionSource` support (`FilledTonalButton`, `SuggestionChip`)
+
+Use the component's built-in `interactionSource` parameter + `collectIsFocusedAsState()` / `collectIsPressedAsState()`.
+
+```
+val interactionSource = remember { MutableInteractionSource() }
+val isFocused by interactionSource.collectIsFocusedAsState()
+val isPressed by interactionSource.collectIsPressedAsState()
+val isActive = isFocused || isPressed
+
+Component(
+    interactionSource = interactionSource,
+    colors = ...(
+        containerColor = when {
+            isAndroidTV && isActive -> MaterialTheme.colorScheme.primary
+            else -> defaultColor
+        }
+    )
+)
+```
+
+Do NOT add explicit `.onFocusChanged` or `.focusable()` modifiers — the component handles these internally via `interactionSource`.
+
+**Why `isActive = isFocused || isPressed`**: Prevents a visual flash when the user clicks — if only `isFocused` were used, the color would revert to default during the press-down phase before navigation fires.
+
+### Pattern B: Components without `interactionSource` (`IconButton`, `Box`/`Row` wrappers)
+
+Use `.onFocusChanged` modifier + `mutableStateOf`.
+
+```
+var isFocused by remember { mutableStateOf(false) }
+
+Component(
+    modifier = Modifier
+        .onFocusChanged { if (isAndroidTV) isFocused = it.isFocused }
+        .clickable(onClick = ...),
+    colors = ...(
+        containerColor = when {
+            isAndroidTV && isFocused -> MaterialTheme.colorScheme.primary
+            else -> defaultColor
+        }
+    )
+)
+```
+
+**On non-TV devices**: `onFocusChanged` is harmless — it simply never fires without focus navigation.
+
+### Color Rules
+
+All components follow the same color mapping:
+
+| State | Background | Content (icon/text) |
+|---|---|---|
+| Not focused (default) | `surfaceVariant.copy(alpha = 0.45f)` or component default | `primary` or component default |
+| Focused / Pressed (TV only) | `MaterialTheme.colorScheme.primary` | `MaterialTheme.colorScheme.onPrimary` |
+
+### Background Addition
+
+Components that originally had no background (`Text` with `clickable`:
+- Reverse list, More episodes, Channel selector) were wrapped in a `Box` (or kept as `Row`) with:
+  - `.clip(RoundedCornerShape(8.dp))`
+  - `.background(...)` with the conditional color
+  - `.padding(horizontal = 12.dp, vertical = 3.dp)` for compact sizing
+  - Vertical offset increased from `large_padding + 6.dp` to `large_padding + 16.dp` to prevent overlap with episode buttons above
+
+### Pitfalls Encountered
+
+1. **`.let {}` with `Modifier`**: Using `.let { if (cond) it.focusable() else it }` broke click handling. The plain `Modifier` returned from the else branch caused unexpected behavior. Fixed by using direct modifier calls or conditional `.onFocusChanged` that's always applied but guarded inside the lambda.
+
+2. **Redundant `.focusable()`**: Adding explicit `.focusable()` before `.clickable()` can interfere with `clickable`'s internal focus handling. Since `clickable` (and button components) already add `focusable()`, never add it manually.
+
+3. **`onFocusChanged` vs `interactionSource`**: For components that support `interactionSource` (buttons, chips), prefer `interactionSource.collectIsFocusedAsState()` over `onFocusChanged` — it's synchronized with the component's own state machine and avoids timing issues.
+
+4. **Missing `interactionSource` parameter**: Creating a `MutableInteractionSource` and using `collectIsFocusedAsState()` on it is useless if the component doesn't receive that `interactionSource` parameter. Always pass it explicitly.
+
+## TV Detection
+
+```
+val isAndroidTV = com.lanlinju.animius.util.isAndroidTV(context)
+// Returns true on Android TV devices, false on phones/tablets
+```
+
+All focus inverse color effects are gated on `isAndroidTV` so phone/tablet behavior is unchanged.

+# Focus Inverse Color — Implementation Spec
 
 ## Problem
 
-On Android TV, buttons in the anime detail page used a default dimming effect when focused via remote control, making it hard to distinguish the focused element. The goal was to replace this with a clear inverse-color effect (like Compose for TV buttons): focused button gets `primary` background with `onPrimary` content.
+Buttons across the app (detail page, search page, video player, etc.) used a default dimming or no effect when focused via D-pad/remote, making it hard to distinguish the focused element. The goal was to replace this with a clear inverse-color effect: focused button gets `primary` background with `onPrimary` content, applied uniformly across all devices (phone, tablet, TV).

+## Context
+
+`AnimeDetailScreen.kt` and `SearchScreen.kt` already have focus inverse-color effects applied to their buttons using two patterns. The remaining ~40 interactive components across 11 files need the same treatment. The existing spec document (`docs/superpowers/specs/2026-06-27-tv-focus-inverse-color-design.md`) describes both patterns in detail.
+
+Decision: all changes are inline — no shared helper/abstraction files — to minimize review burden for upstream PR acceptance.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Every clickable button-like component in the app shows `primary` background + `onPrimary` content when focused
+- Uniform behavior across all devices (D-pad, keyboard, TV remote; transparent on touch-only)
+- Changes are self-contained in existing files for easy upstream review
+
+**Non-Goals:**
+- New abstraction layers, utility composables, or Modifier extensions
+- Behavior changes for touch interaction
+- Custom focus styling (borders, shadows, scaling) beyond the inverse-color pattern
+- Changes to `MediaSmall` cards (already have border-based focus style — intentional)
+
+## Decisions
+
+### 1. Inline vs shared helper → Inline
+
+**Rationale**: This is destined for an upstream PR. Inline changes are self-explanatory in diff review — the reviewer sees the pattern repeated and trusts it. A shared helper file invites design debate ("why this abstraction?") that could block the PR. Each file's change is ~10 lines and trivially revertible per-component.
+
+### 2. Component-to-pattern mapping
+
+| Component | Pattern | Why |
+|---|---|---|
+| `IconButton` | B (`onFocusChanged`) | No `interactionSource` parameter in Material 3 |
+| `Button` / `OutlinedButton` | A (`interactionSource`) | Has `interactionSource` + `colors` parameters |
+| `TextButton` | A (`interactionSource`) | Same as `Button` — has `interactionSource` + `colors` |
+| `FilledTonalButton` | A (already done) | Has `interactionSource` — already implemented on AnimeDetailScreen |
+| `SuggestionChip` | A (already done) | Has `interactionSource` — already implemented on AnimeDetailScreen |
+| `DropdownMenuItem` | B (`onFocusChanged`) | No `interactionSource` or `colors` parameter |
+| Clickable `Box`/`Row`/`Surface` | B (`onFocusChanged`) | Not a button component — needs manual focus tracking |
+
+### 3. AlertDialog TextButton → also inverse
+
+Even though `AlertDialog` buttons are small and transient, TV users navigate them with D-pad and need clear focus feedback. Same pattern as regular `TextButton`.
+
+### 4. Default unfocused colors → preserve existing
+
+Each component keeps its current default unfocused appearance. The inverse-color effect only activates on focus. This means:
+- `BackTopAppBar` IconButton: default `Color.Transparent`, focus → `primary` bg
+- `OutlinedButton` in WarningMessage: default outlined style, focus → `primary` filled
+- `DropdownMenuItem`: default transparent, focus → `primary` bg with `onPrimary` tinted icon
+
+## Risks / Trade-offs
+
+- **DropdownMenuItem text color**: `DropdownMenuItem` doesn't expose a `colors` parameter. The `text` slot content may need a manual `Text` with conditional color. → Mitigation: wrap text in a custom `Text` that reads the focus state.
+- **SegmentedButton** in AppearanceScreen: Material 3 `SegmentedButton` has limited color customization. → If `colors()` API doesn't support focus state, fall back to Pattern B with modifier-based background.
+- **Compile-time verification only**: No runtime focus tests exist. → Validate on TV emulator with `android layout` after each screen.

+## Why
+
+The focus inverse-color effect (focused button gets `primary` background + `onPrimary` content) is currently only implemented on `AnimeDetailScreen` and `SearchScreen`. On TV/non-touch devices, the remaining ~40 interactive components across the app use default dimming or no visible focus feedback, making D-pad navigation confusing. Users can't easily tell which button is focused.
+
+## What Changes
+
+- Extend focus inverse-color effect to all remaining button-like components across all screens, dialogs, and bottom sheets
+- Cover `IconButton`, `Button`, `OutlinedButton`, `TextButton`, `FilledTonalButton`, `SuggestionChip`, `DropdownMenuItem`, and clickable `Box`/`Row` wrappers
+- Follow the two established patterns already in `AnimeDetailScreen.kt`: Pattern A (`interactionSource` + `collectIsFocusedAsState`) for components with `interactionSource` support, and Pattern B (`onFocusChanged`) for components without it
+- No new abstraction files — all changes are inline in existing composables for easy upstream review
+
+## Capabilities
+
+### New Capabilities
+- `tv-focus-inverse-color`: All interactive components (buttons, chips, menu items, clickable surfaces) across the app display inverse colors (`primary` background, `onPrimary` content) when focused via D-pad/keyboard/TV remote
+
+### Modified Capabilities
+<!-- No existing specs to modify -->
+
+## Impact
+
+- Affected files: ~11 composable files across `presentation/component/` and `presentation/screen/`
+- Shared components (`BackTopAppBar`, `WarningMessage`) — fix once, benefits all screens using them
+- No new dependencies, no architecture changes, no API changes
+- Touch-only devices: zero impact (focus events never fire during touch interaction)

+## ADDED Requirements
+
+### Requirement: Focused button inverse color
+All interactive button-like components across the app SHALL display `primary` background with `onPrimary` content color when focused via D-pad, keyboard, or TV remote.
+
+#### Scenario: IconButton receives focus
+- **WHEN** D-pad navigation focuses an `IconButton`
+- **THEN** the button displays `MaterialTheme.colorScheme.primary` as container color and `MaterialTheme.colorScheme.onPrimary` as content (icon) color
+
+#### Scenario: FilledTonalButton receives focus
+- **WHEN** D-pad navigation focuses a `FilledTonalButton`
+- **THEN** the button displays `primary` background with `onPrimary` text/icon
+
+#### Scenario: SuggestionChip receives focus
+- **WHEN** D-pad navigation focuses a `SuggestionChip`
+- **THEN** the chip displays `primary` background with `onPrimary` label
+
+#### Scenario: TextButton receives focus
+- **WHEN** D-pad navigation focuses a `TextButton` (including in `AlertDialog`)

+# TV Focus Inverse Color
+
+## Purpose
+
+Ensure all interactive components across the app provide clear visual feedback when focused via D-pad, keyboard, or TV remote, using an inverse-color pattern: `primary` background with `onPrimary` content.
+
+## Requirements
+
+### Requirement: Focused button inverse color
+All interactive button-like components across the app SHALL display `primary` background with `onPrimary` content color when focused via D-pad, keyboard, or TV remote.
+
+#### Scenario: IconButton receives focus
+- **WHEN** D-pad navigation focuses an `IconButton`
+- **THEN** the button displays `MaterialTheme.colorScheme.primary` as container color and `MaterialTheme.colorScheme.onPrimary` as content (icon) color
+
+#### Scenario: FilledTonalButton receives focus
+- **WHEN** D-pad navigation focuses a `FilledTonalButton`
+- **THEN** the button displays `primary` background with `onPrimary` text/icon
+
+#### Scenario: SuggestionChip receives focus
+- **WHEN** D-pad navigation focuses a `SuggestionChip`
+- **THEN** the chip displays `primary` background with `onPrimary` label
+
+#### Scenario: TextButton receives focus
+- **WHEN** D-pad navigation focuses a `TextButton` (including in `AlertDialog`)
+- **THEN** the button displays `primary` container color with `onPrimary` content color
+
+#### Scenario: OutlinedButton receives focus
+- **WHEN** D-pad navigation focuses an `OutlinedButton`
+- **THEN** the button displays `primary` filled background with `onPrimary` content, overriding its default outlined appearance
+
+#### Scenario: DropdownMenuItem receives focus
+- **WHEN** D-pad navigation focuses a `DropdownMenuItem`
+- **THEN** the item displays `primary` background with `onPrimary`-tinted icon and text
+
+#### Scenario: Clickable Box/Row receives focus
+- **WHEN** D-pad navigation focuses a clickable `Box`, `Row`, or `Surface`
+- **THEN** the container displays `primary` background with `onPrimary`-tinted content
+
+### Requirement: Focus state includes press state
+For components using Pattern A (`interactionSource`), the active focus visual SHALL include the pressed state to prevent visual flash during click.
+
+#### Scenario: Button pressed while focused
+- **WHEN** user presses (clicks) a focused button
+- **THEN** the button SHALL retain the inverse-color appearance (not revert to default) until the press action completes
+
+### Requirement: Touch interaction unaffected
+Focus inverse-color effects SHALL NOT activate during normal touch interaction on touch-only devices.
+
+#### Scenario: Touch tap on phone
+- **WHEN** user taps a button on a touch-only device (phone, tablet without keyboard/D-pad)
+- **THEN** the button SHALL NOT show the focus inverse-color effect; standard Material 3 ripple/press behavior SHALL be preserved
+
+### Requirement: No new abstraction files
+All focus inverse-color implementations SHALL be inline in existing composable files. No new shared helper composable, Modifier extension, or utility file SHALL be introduced.
+
+#### Scenario: Code review of a single screen
+- **WHEN** an upstream reviewer inspects the diff of any single screen file
+- **THEN** the focus inverse-color logic SHALL be self-contained and understandable within that file without referencing new abstraction layers
+
+### Requirement: ListItem focus styling
+When `ListItem`-based components (settings toggles, slider rows) receive focus, the entire row SHALL highlight with `surfaceVariant` background. The headline and supporting text SHALL transition to `primary` color, except where `primary` would conflict with embedded controls (e.g., Switch toggles, Slider tracks).
+
+#### Scenario: Settings toggle row receives focus
+- **WHEN** D-pad navigation focuses a `SwitchPref` or `SettingsItem` row
+- **THEN** the row background becomes `surfaceVariant`, headline text becomes `primary`, and the Switch control remains its default coloring
+
+### Requirement: Slider D-pad navigation
+All `Slider` components SHALL respond to D-pad left/right key events. The step increment SHALL be configurable per slider via a `dpadStep` parameter; when not specified, the slider SHALL use a sensible default based on its range and step count.
+
+#### Scenario: D-pad right on a slider
+- **WHEN** a Slider has focus and the user presses D-pad Right
+- **THEN** the slider value increases by the configured step amount
+
+#### Scenario: D-pad left on a slider
+- **WHEN** a Slider has focus and the user presses D-pad Left
+- **THEN** the slider value decreases by the configured step amount

-description: Implement tasks from an OpenSpec change (Experimental)
----
-
-Implement tasks from an OpenSpec change.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **Select the change**
-
-   If a name is provided, use it. Otherwise:
-   - Infer from conversation context if the user mentioned a change
-   - Auto-select if only one active change exists
-   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
-
-   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
-   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
-
-3. **Get apply instructions**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns:
-   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema)
-   - Progress (total, complete, remaining)
-   - Task list with status
-   - Dynamic instruction based on current state
-
-   **Handle states:**
-   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx:continue`
-   - If `state: "all_done"`: congratulate, suggest archive
-   - Otherwise: proceed to implementation
-
-4. **Read context files**
-
-   Read every file path listed under `contextFiles` from the apply instructions output.
-   The files depend on the schema being used:
-   - **spec-driven**: proposal, specs, design, tasks
-   - Other schemas: follow the contextFiles from CLI output
-
-5. **Show current progress**
-
-   Display:
-   - Schema being used
-   - Progress: "N/M tasks complete"
-   - Remaining tasks overview
-   - Dynamic instruction from CLI
-
-6. **Implement tasks (loop until done or blocked)**
-
-   For each pending task:
-   - Show which task is being worked on
-   - Make the code changes required
-   - Keep changes minimal and focused
-   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
-   - Continue to next task
-
-   **Pause if:**
-   - Task is unclear → ask for clarification
-   - Implementation reveals a design issue → suggest updating artifacts
-   - Error or blocker encountered → report and wait for guidance
-   - User interrupts
-
-7. **On completion or pause, show status**
-
-   Display:
-   - Tasks completed this session
-   - Overall progress: "N/M tasks complete"
-   - If all done: suggest archive
-   - If paused: explain why and wait for guidance
-
-**Output During Implementation**
-
-```
-## Implementing: <change-name> (schema: <schema-name>)
-
-Working on task 3/7: <task description>
-[...implementation happening...]
-✓ Task complete
-
-Working on task 4/7: <task description>
-[...implementation happening...]
-✓ Task complete
-```
-
-**Output On Completion**
-
-```
-## Implementation Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 7/7 tasks complete ✓
-
-### Completed This Session
-- [x] Task 1
-- [x] Task 2
-...
-
-All tasks complete! You can archive this change with `/opsx:archive`.
-```
-
-**Output On Pause (Issue Encountered)**
-
-```
-## Implementation Paused
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 4/7 tasks complete
-
-### Issue Encountered
-<description of the issue>
-
-**Options:**
-1. <option 1>
-2. <option 2>
-3. Other approach
-
-What would you like to do?
-```
-
-**Guardrails**
-- Keep going through tasks until done or blocked
-- Always read context files before starting (from the apply instructions output)
-- If task is ambiguous, pause and ask before implementing
-- If implementation reveals issues, pause and suggest artifact updates
-- Keep code changes minimal and scoped to each task
-- Update task checkbox immediately after completing each task
-- Pause on errors, blockers, or unclear requirements - don't guess
-- Use contextFiles from CLI output, don't assume specific file names
-
-**Fluid Workflow Integration**
-
-This skill supports the "actions on a change" model:
-
-- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
-- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

-description: Archive a completed change in the experimental workflow

-
-Archive a completed change in the experimental workflow.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name after `/opsx:archive` (e.g., `/opsx:archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show only active changes (not already archived).
-   Include the schema used for each change if available.
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check artifact completion status**
-
-   Run `openspec status --change "<name>" --json` to check artifact completion.
-
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used
-   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
-   - `artifacts`: List of artifacts with their status (`done` or other)
-
-   **If any artifacts are not `done`:**
-   - Display warning listing incomplete artifacts
-   - Prompt user for confirmation to continue
-   - Proceed if user confirms
-
-3. **Check task completion status**
-
-   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
-
-   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
-
-   **If incomplete tasks found:**
-   - Display warning showing count of incomplete tasks
-   - Prompt user for confirmation to continue
-   - Proceed if user confirms
-
-   **If no tasks file exists:** Proceed without task-related warning.
-
-4. **Assess delta spec sync state**
-
-   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
-
-   **If delta specs exist:**
-   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
-   - Determine what changes would be applied (adds, modifications, removals, renames)
-   - Show a combined summary before prompting
-
-   **Prompt options:**
-   - If changes needed: "Sync now (recommended)", "Archive without syncing"
-   - If already synced: "Archive now", "Sync anyway", "Cancel"
-
-   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
-
-5. **Perform the archive**
-
-   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
-   ```bash
-   mkdir -p "<planningHome.changesDir>/archive"
-   ```
-
-   Generate target name using current date: `YYYY-MM-DD-<change-name>`
-
-   **Check if target already exists:**
-   - If yes: Fail with error, suggest renaming existing archive or using different date
-   - If no: Move `changeRoot` to the archive directory
-
-   ```bash
-   mv "<changeRoot>" "<planningHome.changesDir>/archive/YYYY-MM-DD-<name>"
-   ```
-
-6. **Display summary**
-
-   Show archive completion summary including:
-   - Change name
-   - Schema that was used
-   - Archive location
-   - Spec sync status (synced / sync skipped / no delta specs)
-   - Note about any warnings (incomplete artifacts/tasks)
-
-**Output On Success**
-
-```
-## Archive Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
-**Specs:** ✓ Synced to main specs
-
-All artifacts complete. All tasks complete.
-```
-
-**Output On Success (No Delta Specs)**
-
-```
-## Archive Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
-**Specs:** No delta specs
-
-All artifacts complete. All tasks complete.
-```
-
-**Output On Success With Warnings**
-
-```
-## Archive Complete (with warnings)
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
-**Specs:** Sync skipped (user chose to skip)
-
-**Warnings:**
-- Archived with 2 incomplete artifacts
-- Archived with 3 incomplete tasks
-- Delta spec sync was skipped (user chose to skip)
-
-Review the archive if this was not intentional.
-```
-
-**Output On Error (Archive Exists)**
-
-```
-## Archive Failed
-
-**Change:** <change-name>
-**Target:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
-
-Target archive directory already exists.
-
-**Options:**
-1. Rename the existing archive
-2. Delete the existing archive if it's a duplicate
-3. Wait until a different date to archive
-```
-
-**Guardrails**
-- Always prompt for change selection if not provided
-- Use artifact graph (openspec status --json) for completion checking
-- Don't block archive on warnings - just inform and confirm
-- Preserve .openspec.yaml when moving to archive (it moves with the directory)
-- Show clear summary of what happened
-- If sync is requested, use the Skill tool to invoke `openspec-sync-specs` (agent-driven)
-- If delta specs exist, always run the sync assessment and show the combined summary before prompting

-description: Enter explore mode - think through ideas, investigate problems, clarify requirements
----
-
-Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
-
-**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
-
-**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: The argument after `/opsx:explore` is whatever the user wants to think about. Could be:
-- A vague idea: "real-time collaboration"
-- A specific problem: "the auth system is getting unwieldy"
-- A change name: "add-dark-mode" (to explore in context of that change)
-- A comparison: "postgres vs sqlite for this"
-- Nothing (just enter explore mode)
-
----
-
-## The Stance
-
-- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
-- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
-- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
-- **Adaptive** - Follow interesting threads, pivot when new information emerges
-- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
-- **Grounded** - Explore the actual codebase when relevant, don't just theorize
-
----
-
-## What You Might Do
-
-Depending on what the user brings, you might:
-
-**Explore the problem space**
-- Ask clarifying questions that emerge from what they said
-- Challenge assumptions
-- Reframe the problem
-- Find analogies
-
-**Investigate the codebase**
-- Map existing architecture relevant to the discussion
-- Find integration points
-- Identify patterns already in use
-- Surface hidden complexity
-
-**Compare options**
-- Brainstorm multiple approaches
-- Build comparison tables
-- Sketch tradeoffs
-- Recommend a path (if asked)
-
-**Visualize**

-
----
-
-## OpenSpec Awareness
-
-You have full context of the OpenSpec system. Use it naturally, don't force it.
-
-### Check for context
-
-At the start, quickly check what exists:
-```bash
-openspec list --json
-```
-
-This tells you:
-- If there are active changes
-- Their names, schemas, and status
-- What the user might be working on
-
-If the user mentioned a specific change name, read its artifacts for context.
-
-### When no change exists
-
-Think freely. When insights crystallize, you might offer:
-
-- "This feels solid enough to start a change. Want me to create a proposal?"
-- Or keep exploring - no pressure to formalize
-
-### When a change exists
-
-If the user mentions a change or you detect one is relevant:
-
-1. **Resolve and read existing artifacts for context**
-   - Run `openspec status --change "<name>" --json`.
-   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
-   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
-
-2. **Reference them naturally in conversation**
-   - "Your design mentions using Redis, but we just realized SQLite fits better..."
-   - "The proposal scopes this to premium users, but we're now thinking everyone..."
-
-3. **Offer to capture when decisions are made**
-
-    | Insight Type               | Where to Capture               |
-    |----------------------------|--------------------------------|
-    | New requirement discovered | `specs/<capability>/spec.md` |
-    | Requirement changed        | `specs/<capability>/spec.md` |
-    | Design decision made       | `design.md`                  |
-    | Scope changed              | `proposal.md`                |
-    | New work identified        | `tasks.md`                   |
-    | Assumption invalidated     | Relevant artifact              |
-
-   Example offers:
-   - "That's a design decision. Capture it in design.md?"
-   - "This is a new requirement. Add it to specs?"
-   - "This changes scope. Update the proposal?"
-
-4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
-
----
-
-## What You Don't Have To Do
-
-- Follow a script
-- Ask the same questions every time
-- Produce a specific artifact
-- Reach a conclusion
-- Stay on topic if a tangent is valuable
-- Be brief (this is thinking time)
-
----
-
-## Ending Discovery
-
-There's no required ending. Discovery might:
-
-- **Flow into a proposal**: "Ready to start? I can create a change proposal."
-- **Result in artifact updates**: "Updated design.md with these decisions"
-- **Just provide clarity**: User has what they need, moves on
-- **Continue later**: "We can pick this up anytime"
-
-When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
-
----
-
-## Guardrails
-
-- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
-- **Don't fake understanding** - If something is unclear, dig deeper
-- **Don't rush** - Discovery is thinking time, not task time
-- **Don't force structure** - Let patterns emerge naturally
-- **Don't auto-capture** - Offer to save insights, don't just do it
-- **Do visualize** - A good diagram is worth many paragraphs
-- **Do explore the codebase** - Ground discussions in reality
-- **Do question assumptions** - Including the user's and your own

-Propose a new change - create the change and generate all artifacts in one step.

-I'll create a change with artifacts:
-- proposal.md (what & why)
-- design.md (how)
-- tasks.md (implementation steps)
-
-When ready to implement, run /opsx:apply

-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: The argument after `/opsx:propose` is the change name (kebab-case), OR a description of what the user wants to build.
-
-**Steps**
-
-1. **If no input provided, ask what they want to build**
-
-   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
-   > "What change do you want to work on? Describe what you want to build or fix."
-
-   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
-
-   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
-
-2. **Create the change directory**
-   ```bash
-   openspec new change "<name>"
-   ```
-   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
-
-3. **Get the artifact build order**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to get:
-   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
-   - `artifacts`: list of all artifacts with their status and dependencies
-   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
-
-4. **Create artifacts in sequence until apply-ready**
-
-   Use the **TodoWrite tool** to track progress through the artifacts.
-
-   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
-
-   a. **For each artifact that is `ready` (dependencies satisfied)**:
-      - Get instructions:
-        ```bash
-        openspec instructions <artifact-id> --change "<name>" --json
-        ```
-      - The instructions JSON includes:
-        - `context`: Project background (constraints for you - do NOT include in output)
-        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
-        - `template`: The structure to use for your output file
-        - `instruction`: Schema-specific guidance for this artifact type
-        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
-        - `dependencies`: Completed artifacts to read for context
-      - Read any completed dependency files for context
-      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
-      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
-      - Show brief progress: "Created <artifact-id>"
-
-   b. **Continue until all `applyRequires` artifacts are complete**
-      - After creating each artifact, re-run `openspec status --change "<name>" --json`
-      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
-      - Stop when all `applyRequires` artifacts are done
-
-   c. **If an artifact requires user input** (unclear context):
-      - Use **AskUserQuestion tool** to clarify
-      - Then continue with creation
-
-5. **Show final status**
-   ```bash
-   openspec status --change "<name>"
-   ```
-
-**Output**
-
-After completing all artifacts, summarize:
-- Change name and location
-- List of artifacts created with brief descriptions
-- What's ready: "All artifacts created! Ready for implementation."
-- Prompt: "Run `/opsx:apply` to start implementing."
-
-**Artifact Creation Guidelines**
-
-- Follow the `instruction` field from `openspec instructions` for each artifact type
-- The schema defines what each artifact should contain - follow it
-- Read dependency artifacts for context before creating new ones
-- Use `template` as the structure for your output file - fill in its sections
-- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
-  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
-  - These guide what you write, but should never appear in the output
-
-**Guardrails**
-- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
-- Always read dependency artifacts before creating a new one
-- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
-- If a change with that name already exists, ask if user wants to continue it or create a new one
-- Verify each artifact file exists after writing before proceeding to next

-description: Sync delta specs from a change to main specs
----
-
-Sync delta specs from a change to main specs.
-
-This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name after `/opsx:sync` (e.g., `/opsx:sync add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have delta specs (under `specs/` directory).
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Resolve change context**
-
-   Run:
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-
-3. **Find delta specs**
-
-   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
-
-   Each delta spec file contains sections like:
-   - `## ADDED Requirements` - New requirements to add
-   - `## MODIFIED Requirements` - Changes to existing requirements
-   - `## REMOVED Requirements` - Requirements to remove
-   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
-
-   If no delta specs found, inform user and stop.
-
-4. **For each delta spec, apply changes to main specs**
-
-   For each repo-local capability delta spec path returned by the CLI:
-
-   a. **Read the delta spec** to understand the intended changes
-
-   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
-
-   c. **Apply changes intelligently**:
-
-      **ADDED Requirements:**
-      - If requirement doesn't exist in main spec → add it
-      - If requirement already exists → update it to match (treat as implicit MODIFIED)
-
-      **MODIFIED Requirements:**
-      - Find the requirement in main spec
-      - Apply the changes - this can be:
-        - Adding new scenarios (don't need to copy existing ones)
-        - Modifying existing scenarios
-        - Changing the requirement description
-      - Preserve scenarios/content not mentioned in the delta
-
-      **REMOVED Requirements:**
-      - Remove the entire requirement block from main spec
-
-      **RENAMED Requirements:**
-      - Find the FROM requirement, rename to TO
-
-   d. **Create new main spec** if capability doesn't exist yet:
-      - Create `openspec/specs/<capability>/spec.md`
-      - Add Purpose section (can be brief, mark as TBD)
-      - Add Requirements section with the ADDED requirements
-
-5. **Show summary**
-
-   After applying all changes, summarize:
-   - Which capabilities were updated
-   - What changes were made (requirements added/modified/removed/renamed)
-
-**Delta Spec Format Reference**
-
-```markdown
-## ADDED Requirements
-
-### Requirement: New Feature
-The system SHALL do something new.
-
-#### Scenario: Basic case
-- **WHEN** user does X
-- **THEN** system does Y
-
-## MODIFIED Requirements
-
-### Requirement: Existing Feature
-#### Scenario: New scenario to add
-- **WHEN** user does A
-- **THEN** system does B
-
-## REMOVED Requirements
-
-### Requirement: Deprecated Feature
-
-## RENAMED Requirements
-
-- FROM: `### Requirement: Old Name`
-- TO: `### Requirement: New Name`
-```
-
-**Key Principle: Intelligent Merging**
-
-Unlike programmatic merging, you can apply **partial updates**:
-- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
-- The delta represents *intent*, not a wholesale replacement
-- Use your judgment to merge changes sensibly
-
-**Output On Success**
-
-```
-## Specs Synced: <change-name>
-
-Updated main specs:
-
-**<capability-1>**:
-- Added requirement: "New Feature"
-- Modified requirement: "Existing Feature" (added 1 scenario)
-
-**<capability-2>**:
-- Created new spec file
-- Added requirement: "Another Feature"
-
-Main specs are now updated. The change remains active - archive when implementation is complete.
-```
-
-**Guardrails**
-- Read both delta and main specs before making changes
-- Preserve existing content not mentioned in delta
-- If something is unclear, ask for clarification
-- Show what you're changing as you go
-- The operation should be idempotent - running twice should give same result

-Implement tasks from an OpenSpec change.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **Select the change**
-
-   If a name is provided, use it. Otherwise:
-   - Infer from conversation context if the user mentioned a change
-   - Auto-select if only one active change exists
-   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
-
-   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
-   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
-
-3. **Get apply instructions**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns:
-   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
-   - Progress (total, complete, remaining)
-   - Task list with status
-   - Dynamic instruction based on current state
-
-   **Handle states:**
-   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
-   - If `state: "all_done"`: congratulate, suggest archive
-   - Otherwise: proceed to implementation
-
-4. **Read context files**
-
-   Read every file path listed under `contextFiles` from the apply instructions output.
-   The files depend on the schema being used:
-   - **spec-driven**: proposal, specs, design, tasks
-   - Other schemas: follow the contextFiles from CLI output
-
-5. **Show current progress**
-
-   Display:
-   - Schema being used
-   - Progress: "N/M tasks complete"
-   - Remaining tasks overview
-   - Dynamic instruction from CLI
-
-6. **Implement tasks (loop until done or blocked)**
-
-   For each pending task:
-   - Show which task is being worked on
-   - Make the code changes required
-   - Keep changes minimal and focused
-   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
-   - Continue to next task
-
-   **Pause if:**
-   - Task is unclear → ask for clarification
-   - Implementation reveals a design issue → suggest updating artifacts
-   - Error or blocker encountered → report and wait for guidance
-   - User interrupts
-
-7. **On completion or pause, show status**
-
-   Display:
-   - Tasks completed this session
-   - Overall progress: "N/M tasks complete"
-   - If all done: suggest archive
-   - If paused: explain why and wait for guidance
-
-**Output During Implementation**
-
-```
-## Implementing: <change-name> (schema: <schema-name>)
-
-Working on task 3/7: <task description>
-[...implementation happening...]
-✓ Task complete
-
-Working on task 4/7: <task description>
-[...implementation happening...]
-✓ Task complete
-```
-
-**Output On Completion**
-
-```
-## Implementation Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 7/7 tasks complete ✓
-
-### Completed This Session
-- [x] Task 1
-- [x] Task 2
-...
-
-All tasks complete! Ready to archive this change.
-```
-
-**Output On Pause (Issue Encountered)**
-
-```
-## Implementation Paused
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 4/7 tasks complete
-
-### Issue Encountered
-<description of the issue>
-
-**Options:**
-1. <option 1>
-2. <option 2>
-3. Other approach
-
-What would you like to do?
-```
-
-**Guardrails**
-- Keep going through tasks until done or blocked
-- Always read context files before starting (from the apply instructions output)
-- If task is ambiguous, pause and ask before implementing
-- If implementation reveals issues, pause and suggest artifact updates
-- Keep code changes minimal and scoped to each task
-- Update task checkbox immediately after completing each task
-- Pause on errors, blockers, or unclear requirements - don't guess
-- Use contextFiles from CLI output, don't assume specific file names
-
-**Fluid Workflow Integration**
-
-This skill supports the "actions on a change" model:
-
-- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
-- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show only active changes (not already archived).
-   Include the schema used for each change if available.
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check artifact completion status**
-
-   Run `openspec status --change "<name>" --json` to check artifact completion.
-
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used
-   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
-   - `artifacts`: List of artifacts with their status (`done` or other)
-
-   **If any artifacts are not `done`:**
-   - Display warning listing incomplete artifacts
-   - Use **AskUserQuestion tool** to confirm user wants to proceed
-   - Proceed if user confirms
-
-3. **Check task completion status**
-
-   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
-
-   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
-
-   **If incomplete tasks found:**
-   - Display warning showing count of incomplete tasks
-   - Use **AskUserQuestion tool** to confirm user wants to proceed
-   - Proceed if user confirms
-
-   **If no tasks file exists:** Proceed without task-related warning.
-
-4. **Assess delta spec sync state**
-
-   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
-
-   **If delta specs exist:**
-   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
-   - Determine what changes would be applied (adds, modifications, removals, renames)
-   - Show a combined summary before prompting
-
-   **Prompt options:**
-   - If changes needed: "Sync now (recommended)", "Archive without syncing"
-   - If already synced: "Archive now", "Sync anyway", "Cancel"
-
-   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
-
-5. **Perform the archive**
-
-   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
-   ```bash
-   mkdir -p "<planningHome.changesDir>/archive"
-   ```
-
-   Generate target name using current date: `YYYY-MM-DD-<change-name>`
-
-   **Check if target already exists:**
-   - If yes: Fail with error, suggest renaming existing archive or using different date
-   - If no: Move `changeRoot` to the archive directory
-
-   ```bash
-   mv "<changeRoot>" "<planningHome.changesDir>/archive/YYYY-MM-DD-<name>"
-   ```
-
-6. **Display summary**
-
-   Show archive completion summary including:
-   - Change name
-   - Schema that was used
-   - Archive location
-   - Whether specs were synced (if applicable)
-   - Note about any warnings (incomplete artifacts/tasks)
-
-**Output On Success**
-
-```
-## Archive Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
-**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
-
-All artifacts complete. All tasks complete.
-```
-
-**Guardrails**
-- Always prompt for change selection if not provided
-- Use artifact graph (openspec status --json) for completion checking
-- Don't block archive on warnings - just inform and confirm
-- Preserve .openspec.yaml when moving to archive (it moves with the directory)
-- Show clear summary of what happened
-- If sync is requested, use openspec-sync-specs approach (agent-driven)
-- If delta specs exist, always run the sync assessment and show the combined summary before prompting

-description: Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
-license: MIT
-compatibility: Requires openspec CLI.
-metadata:
-  author: openspec
-  version: "1.0"
-  generatedBy: "1.5.0"
----
-
-Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
-
-**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
-
-**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
----
-
-## The Stance
-
-- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
-- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
-- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
-- **Adaptive** - Follow interesting threads, pivot when new information emerges
-- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
-- **Grounded** - Explore the actual codebase when relevant, don't just theorize
-
----
-
-## What You Might Do
-
-Depending on what the user brings, you might:
-
-**Explore the problem space**
-- Ask clarifying questions that emerge from what they said
-- Challenge assumptions
-- Reframe the problem
-- Find analogies
-
-**Investigate the codebase**
-- Map existing architecture relevant to the discussion
-- Find integration points
-- Identify patterns already in use
-- Surface hidden complexity
-
-**Compare options**
-- Brainstorm multiple approaches
-- Build comparison tables
-- Sketch tradeoffs
-- Recommend a path (if asked)
-
-**Visualize**

-## OpenSpec Awareness
-
-You have full context of the OpenSpec system. Use it naturally, don't force it.
-
-### Check for context
-
-At the start, quickly check what exists:
-```bash
-openspec list --json
-```
-
-This tells you:
-- If there are active changes
-- Their names, schemas, and status
-- What the user might be working on
-
-### When no change exists
-
-Think freely. When insights crystallize, you might offer:
-
-- "This feels solid enough to start a change. Want me to create a proposal?"
-- Or keep exploring - no pressure to formalize
-
-### When a change exists
-
-If the user mentions a change or you detect one is relevant:
-
-1. **Resolve and read existing artifacts for context**
-   - Run `openspec status --change "<name>" --json`.
-   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
-   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
-
-2. **Reference them naturally in conversation**
-   - "Your design mentions using Redis, but we just realized SQLite fits better..."
-   - "The proposal scopes this to premium users, but we're now thinking everyone..."
-
-3. **Offer to capture when decisions are made**
-
-    | Insight Type               | Where to Capture               |
-    |----------------------------|--------------------------------|
-    | New requirement discovered | `specs/<capability>/spec.md` |
-    | Requirement changed        | `specs/<capability>/spec.md` |
-    | Design decision made       | `design.md`                  |
-    | Scope changed              | `proposal.md`                |
-    | New work identified        | `tasks.md`                   |
-    | Assumption invalidated     | Relevant artifact              |
-
-   Example offers:
-   - "That's a design decision. Capture it in design.md?"
-   - "This is a new requirement. Add it to specs?"
-   - "This changes scope. Update the proposal?"
-
-4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
-
----
-
-## What You Don't Have To Do
-
-- Follow a script
-- Ask the same questions every time
-- Produce a specific artifact
-- Reach a conclusion
-- Stay on topic if a tangent is valuable
-- Be brief (this is thinking time)
-
----
-
-## Handling Different Entry Points
-
-**User brings a vague idea:**
-```
-User: I'm thinking about adding real-time collaboration
-

-## Ending Discovery
-
-There's no required ending. Discovery might:
-
-- **Flow into a proposal**: "Ready to start? I can create a change proposal."
-- **Result in artifact updates**: "Updated design.md with these decisions"
-- **Just provide clarity**: User has what they need, moves on
-- **Continue later**: "We can pick this up anytime"
-
-When it feels like things are crystallizing, you might summarize:
-
-```
-## What We Figured Out
-
-**The problem**: [crystallized understanding]
-
-**The approach**: [if one emerged]
-
-**Open questions**: [if any remain]
-
-**Next steps** (if ready):
-- Create a change proposal
-- Keep exploring: just keep talking
-```
-
-But this summary is optional. Sometimes the thinking IS the value.
-

-
-## Guardrails
-
-- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
-- **Don't fake understanding** - If something is unclear, dig deeper
-- **Don't rush** - Discovery is thinking time, not task time
-- **Don't force structure** - Let patterns emerge naturally
-- **Don't auto-capture** - Offer to save insights, don't just do it
-- **Do visualize** - A good diagram is worth many paragraphs
-- **Do explore the codebase** - Ground discussions in reality
-- **Do question assumptions** - Including the user's and your own

-Propose a new change - create the change and generate all artifacts in one step.
-
-I'll create a change with artifacts:
-- proposal.md (what & why)
-- design.md (how)
-- tasks.md (implementation steps)
-
-When ready to implement, run /opsx:apply
-
----
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
-
-**Steps**
-
-1. **If no clear input provided, ask what they want to build**
-
-   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
-   > "What change do you want to work on? Describe what you want to build or fix."
-
-   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
-
-   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
-
-2. **Create the change directory**
-   ```bash
-   openspec new change "<name>"
-   ```
-   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
-
-3. **Get the artifact build order**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to get:
-   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
-   - `artifacts`: list of all artifacts with their status and dependencies
-   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
-
-4. **Create artifacts in sequence until apply-ready**
-
-   Use the **TodoWrite tool** to track progress through the artifacts.
-
-   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
-
-   a. **For each artifact that is `ready` (dependencies satisfied)**:
-      - Get instructions:
-        ```bash
-        openspec instructions <artifact-id> --change "<name>" --json
-        ```
-      - The instructions JSON includes:
-        - `context`: Project background (constraints for you - do NOT include in output)
-        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
-        - `template`: The structure to use for your output file
-        - `instruction`: Schema-specific guidance for this artifact type
-        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
-        - `dependencies`: Completed artifacts to read for context
-      - Read any completed dependency files for context
-      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
-      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
-      - Show brief progress: "Created <artifact-id>"
-
-   b. **Continue until all `applyRequires` artifacts are complete**
-      - After creating each artifact, re-run `openspec status --change "<name>" --json`
-      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
-      - Stop when all `applyRequires` artifacts are done
-
-   c. **If an artifact requires user input** (unclear context):
-      - Use **AskUserQuestion tool** to clarify
-      - Then continue with creation
-
-5. **Show final status**
-   ```bash
-   openspec status --change "<name>"
-   ```
-
-**Output**
-
-After completing all artifacts, summarize:
-- Change name and location
-- List of artifacts created with brief descriptions
-- What's ready: "All artifacts created! Ready for implementation."
-- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
-
-**Artifact Creation Guidelines**
-
-- Follow the `instruction` field from `openspec instructions` for each artifact type
-- The schema defines what each artifact should contain - follow it
-- Read dependency artifacts for context before creating new ones
-- Use `template` as the structure for your output file - fill in its sections
-- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
-  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
-  - These guide what you write, but should never appear in the output
-
-**Guardrails**
-- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
-- Always read dependency artifacts before creating a new one
-- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
-- If a change with that name already exists, ask if user wants to continue it or create a new one
-- Verify each artifact file exists after writing before proceeding to next

-name: openspec-sync-specs
-description: Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.
-license: MIT
-compatibility: Requires openspec CLI.
-metadata:
-  author: openspec
-  version: "1.0"
-  generatedBy: "1.5.0"
----
-
-Sync delta specs from a change to main specs.
-
-This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have delta specs (under `specs/` directory).
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Resolve change context**
-
-   Run:
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-
-3. **Find delta specs**
-
-   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
-
-   Each delta spec file contains sections like:
-   - `## ADDED Requirements` - New requirements to add
-   - `## MODIFIED Requirements` - Changes to existing requirements
-   - `## REMOVED Requirements` - Requirements to remove
-   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
-
-   If no delta specs found, inform user and stop.
-
-4. **For each delta spec, apply changes to main specs**
-
-   For each repo-local capability delta spec path returned by the CLI:
-
-   a. **Read the delta spec** to understand the intended changes
-
-   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
-
-   c. **Apply changes intelligently**:
-
-      **ADDED Requirements:**
-      - If requirement doesn't exist in main spec → add it
-      - If requirement already exists → update it to match (treat as implicit MODIFIED)
-
-      **MODIFIED Requirements:**
-      - Find the requirement in main spec
-      - Apply the changes - this can be:
-        - Adding new scenarios (don't need to copy existing ones)
-        - Modifying existing scenarios
-        - Changing the requirement description
-      - Preserve scenarios/content not mentioned in the delta
-
-      **REMOVED Requirements:**
-      - Remove the entire requirement block from main spec
-
-      **RENAMED Requirements:**
-      - Find the FROM requirement, rename to TO
-
-   d. **Create new main spec** if capability doesn't exist yet:
-      - Create `openspec/specs/<capability>/spec.md`
-      - Add Purpose section (can be brief, mark as TBD)
-      - Add Requirements section with the ADDED requirements
-
-5. **Show summary**
-
-   After applying all changes, summarize:
-   - Which capabilities were updated
-   - What changes were made (requirements added/modified/removed/renamed)
-
-**Delta Spec Format Reference**
-
-```markdown
-## ADDED Requirements
-
-### Requirement: New Feature
-The system SHALL do something new.
-
-#### Scenario: Basic case
-- **WHEN** user does X
-- **THEN** system does Y
-
-## MODIFIED Requirements
-
-### Requirement: Existing Feature
-#### Scenario: New scenario to add
-- **WHEN** user does A
-- **THEN** system does B
-
-## REMOVED Requirements
-
-### Requirement: Deprecated Feature
-
-## RENAMED Requirements
-
-- FROM: `### Requirement: Old Name`
-- TO: `### Requirement: New Name`
-```
-
-**Key Principle: Intelligent Merging**
-
-Unlike programmatic merging, you can apply **partial updates**:
-- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
-- The delta represents *intent*, not a wholesale replacement
-- Use your judgment to merge changes sensibly
-
-**Output On Success**
-
-```
-## Specs Synced: <change-name>
-
-Updated main specs:
-
-**<capability-1>**:
-- Added requirement: "New Feature"
-- Modified requirement: "Existing Feature" (added 1 scenario)
-
-**<capability-2>**:
-- Created new spec file
-- Added requirement: "Another Feature"
-
-Main specs are now updated. The change remains active - archive when implementation is complete.
-```
-
-**Guardrails**
-- Read both delta and main specs before making changes
-- Preserve existing content not mentioned in delta
-- If something is unclear, ask for clarification
-- Show what you're changing as you go
-- The operation should be idempotent - running twice should give same result

----
-
-Implement tasks from an OpenSpec change.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **Select the change**
-
-   If a name is provided, use it. Otherwise:
-   - Infer from conversation context if the user mentioned a change
-   - Auto-select if only one active change exists
-   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
-
-   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
-   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
-
-3. **Get apply instructions**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns:
-   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema)
-   - Progress (total, complete, remaining)
-   - Task list with status
-   - Dynamic instruction based on current state
-
-   **Handle states:**
-   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx:continue`
-   - If `state: "all_done"`: congratulate, suggest archive
-   - Otherwise: proceed to implementation
-
-4. **Read context files**
-
-   Read every file path listed under `contextFiles` from the apply instructions output.
-   The files depend on the schema being used:
-   - **spec-driven**: proposal, specs, design, tasks
-   - Other schemas: follow the contextFiles from CLI output
-
-5. **Show current progress**
-
-   Display:
-   - Schema being used
-   - Progress: "N/M tasks complete"
-   - Remaining tasks overview
-   - Dynamic instruction from CLI
-
-6. **Implement tasks (loop until done or blocked)**
-
-   For each pending task:
-   - Show which task is being worked on
-   - Make the code changes required
-   - Keep changes minimal and focused
-   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
-   - Continue to next task
-
-   **Pause if:**
-   - Task is unclear → ask for clarification
-   - Implementation reveals a design issue → suggest updating artifacts
-   - Error or blocker encountered → report and wait for guidance
-   - User interrupts
-
-7. **On completion or pause, show status**
-
-   Display:
-   - Tasks completed this session
-   - Overall progress: "N/M tasks complete"
-   - If all done: suggest archive

-What would you like to do?
-```
-
-**Guardrails**
-- Keep going through tasks until done or blocked
-- Always read context files before starting (from the apply instructions output)
-- If task is ambiguous, pause and ask before implementing
-- If implementation reveals issues, pause and suggest artifact updates
-- Keep code changes minimal and scoped to each task
-- Update task checkbox immediately after completing each task
-- Pause on errors, blockers, or unclear requirements - don't guess
-- Use contextFiles from CLI output, don't assume specific file names
-
-**Fluid Workflow Integration**
-
-This skill supports the "actions on a change" model:
-
-- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
-- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

-
-Archive a completed change in the experimental workflow.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name after `/opsx:archive` (e.g., `/opsx:archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show only active changes (not already archived).
-   Include the schema used for each change if available.
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check artifact completion status**
-
-   Run `openspec status --change "<name>" --json` to check artifact completion.
-
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used
-   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
-   - `artifacts`: List of artifacts with their status (`done` or other)
-
-   **If any artifacts are not `done`:**
-   - Display warning listing incomplete artifacts
-   - Prompt user for confirmation to continue
-   - Proceed if user confirms
-
-3. **Check task completion status**
-
-   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
-
-   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
-
-   **If incomplete tasks found:**
-   - Display warning showing count of incomplete tasks
-   - Prompt user for confirmation to continue
-   - Proceed if user confirms
-
-   **If no tasks file exists:** Proceed without task-related warning.
-
-4. **Assess delta spec sync state**
-
-   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
-
-   **If delta specs exist:**
-   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
-   - Determine what changes would be applied (adds, modifications, removals, renames)
-   - Show a combined summary before prompting
-
-   **Prompt options:**
-   - If changes needed: "Sync now (recommended)", "Archive without syncing"
-   - If already synced: "Archive now", "Sync anyway", "Cancel"
-
-   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
-
-5. **Perform the archive**
-
-   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
-   ```bash
-   mkdir -p "<planningHome.changesDir>/archive"
-   ```
-
-   Generate target name using current date: `YYYY-MM-DD-<change-name>`
-
-   **Check if target already exists:**
-   - If yes: Fail with error, suggest renaming existing archive or using different date
-   - If no: Move `changeRoot` to the archive directory
-
-   ```bash
-   mv "<changeRoot>" "<planningHome.changesDir>/archive/YYYY-MM-DD-<name>"
-   ```
-
-6. **Display summary**
-
-   Show archive completion summary including:
-   - Change name
-   - Schema that was used
-   - Archive location
-   - Spec sync status (synced / sync skipped / no delta specs)
-   - Note about any warnings (incomplete artifacts/tasks)
-
-**Output On Success**
-
-```
-## Archive Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
-**Specs:** ✓ Synced to main specs
-
-All artifacts complete. All tasks complete.
-```
-
-**Output On Success (No Delta Specs)**
-
-```
-## Archive Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
-**Specs:** No delta specs
-
-All artifacts complete. All tasks complete.
-```
-
-**Output On Success With Warnings**
-
-```
-## Archive Complete (with warnings)
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
-**Specs:** Sync skipped (user chose to skip)
-
-**Warnings:**
-- Archived with 2 incomplete artifacts
-- Archived with 3 incomplete tasks
-- Delta spec sync was skipped (user chose to skip)
-
-Review the archive if this was not intentional.
-```
-
-**Output On Error (Archive Exists)**
-
-```
-## Archive Failed
-
-**Change:** <change-name>
-**Target:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
-
-Target archive directory already exists.
-
-**Options:**
-1. Rename the existing archive
-2. Delete the existing archive if it's a duplicate
-3. Wait until a different date to archive
-```
-
-**Guardrails**
-- Always prompt for change selection if not provided
-- Use artifact graph (openspec status --json) for completion checking
-- Don't block archive on warnings - just inform and confirm
-- Preserve .openspec.yaml when moving to archive (it moves with the directory)
-- Show clear summary of what happened
-- If sync is requested, use the Skill tool to invoke `openspec-sync-specs` (agent-driven)
-- If delta specs exist, always run the sync assessment and show the combined summary before prompting

-description: Enter explore mode - think through ideas, investigate problems, clarify requirements
----
-
-Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
-
-**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
-
-**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: The argument after `/opsx:explore` is whatever the user wants to think about. Could be:
-- A vague idea: "real-time collaboration"
-- A specific problem: "the auth system is getting unwieldy"
-- A change name: "add-dark-mode" (to explore in context of that change)
-- A comparison: "postgres vs sqlite for this"
-- Nothing (just enter explore mode)
-
----
-
-## The Stance
-
-- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
-- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
-- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
-- **Adaptive** - Follow interesting threads, pivot when new information emerges
-- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
-- **Grounded** - Explore the actual codebase when relevant, don't just theorize
-
----
-
-## What You Might Do
-
-Depending on what the user brings, you might:
-
-**Explore the problem space**
-- Ask clarifying questions that emerge from what they said
-- Challenge assumptions
-- Reframe the problem
-- Find analogies
-
-**Investigate the codebase**
-- Map existing architecture relevant to the discussion
-- Find integration points
-- Identify patterns already in use
-- Surface hidden complexity
-
-**Compare options**
-- Brainstorm multiple approaches
-- Build comparison tables
-- Sketch tradeoffs
-- Recommend a path (if asked)
-
-**Visualize**

----
-
-## OpenSpec Awareness
-
-You have full context of the OpenSpec system. Use it naturally, don't force it.
-
-### Check for context
-
-At the start, quickly check what exists:
-```bash
-openspec list --json
-```
-
-This tells you:
-- If there are active changes
-- Their names, schemas, and status
-- What the user might be working on
-
-If the user mentioned a specific change name, read its artifacts for context.
-
-### When no change exists
-
-Think freely. When insights crystallize, you might offer:
-
-- "This feels solid enough to start a change. Want me to create a proposal?"
-- Or keep exploring - no pressure to formalize
-
-### When a change exists
-
-If the user mentions a change or you detect one is relevant:
-
-1. **Resolve and read existing artifacts for context**
-   - Run `openspec status --change "<name>" --json`.
-   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
-   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
-
-2. **Reference them naturally in conversation**
-   - "Your design mentions using Redis, but we just realized SQLite fits better..."
-   - "The proposal scopes this to premium users, but we're now thinking everyone..."
-
-3. **Offer to capture when decisions are made**
-
-    | Insight Type               | Where to Capture               |
-    |----------------------------|--------------------------------|
-    | New requirement discovered | `specs/<capability>/spec.md` |
-    | Requirement changed        | `specs/<capability>/spec.md` |
-    | Design decision made       | `design.md`                  |
-    | Scope changed              | `proposal.md`                |
-    | New work identified        | `tasks.md`                   |
-    | Assumption invalidated     | Relevant artifact              |
-
-   Example offers:
-   - "That's a design decision. Capture it in design.md?"
-   - "This is a new requirement. Add it to specs?"
-   - "This changes scope. Update the proposal?"
-
-4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
-
----
-
-## What You Don't Have To Do
-
-- Follow a script
-- Ask the same questions every time
-- Produce a specific artifact
-- Reach a conclusion
-- Stay on topic if a tangent is valuable
-- Be brief (this is thinking time)
-
----
-
-## Ending Discovery
-
-There's no required ending. Discovery might:
-
-- **Flow into a proposal**: "Ready to start? I can create a change proposal."
-- **Result in artifact updates**: "Updated design.md with these decisions"
-- **Just provide clarity**: User has what they need, moves on
-- **Continue later**: "We can pick this up anytime"
-
-When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
-
----
-
-## Guardrails
-
-- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
-- **Don't fake understanding** - If something is unclear, dig deeper
-- **Don't rush** - Discovery is thinking time, not task time
-- **Don't force structure** - Let patterns emerge naturally
-- **Don't auto-capture** - Offer to save insights, don't just do it
-- **Do visualize** - A good diagram is worth many paragraphs
-- **Do explore the codebase** - Ground discussions in reality
-- **Do question assumptions** - Including the user's and your own

Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: The argument after `/opsx:propose` is the change name (kebab-case), OR a description of what the user wants to build.
-
-**Steps**
-
-1. **If no input provided, ask what they want to build**
-
-   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
-   > "What change do you want to work on? Describe what you want to build or fix."
-
-   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
-
-   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
-
-2. **Create the change directory**
-   ```bash
-   openspec new change "<name>"
-   ```
-   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
-
-3. **Get the artifact build order**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to get:
-   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
-   - `artifacts`: list of all artifacts with their status and dependencies
-   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
-
-4. **Create artifacts in sequence until apply-ready**
-
-   Use the **TodoWrite tool** to track progress through the artifacts.
-
-   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
-
-   a. **For each artifact that is `ready` (dependencies satisfied)**:
-      - Get instructions:
-        ```bash
-        openspec instructions <artifact-id> --change "<name>" --json
-        ```
-      - The instructions JSON includes:
-        - `context`: Project background (constraints for you - do NOT include in output)
-        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
-        - `template`: The structure to use for your output file
-        - `instruction`: Schema-specific guidance for this artifact type
-        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
-        - `dependencies`: Completed artifacts to read for context
-      - Read any completed dependency files for context
-      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
-      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
-      - Show brief progress: "Created <artifact-id>"
-
-   b. **Continue until all `applyRequires` artifacts are complete**
-      - After creating each artifact, re-run `openspec status --change "<name>" --json`
-      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
-      - Stop when all `applyRequires` artifacts are done
-
-   c. **If an artifact requires user input** (unclear context):
-      - Use **AskUserQuestion tool** to clarify
-      - Then continue with creation
-
-5. **Show final status**
-   ```bash
-   openspec status --change "<name>"
-   ```
-
-**Output**
-
-After completing all artifacts, summarize:
-- Change name and location
-- List of artifacts created with brief descriptions
-- What's ready: "All artifacts created! Ready for implementation."
-- Prompt: "Run `/opsx:apply` to start implementing."
-
-**Artifact Creation Guidelines**
-
-- Follow the `instruction` field from `openspec instructions` for each artifact type
-- The schema defines what each artifact should contain - follow it
-- Read dependency artifacts for context before creating new ones
-- Use `template` as the structure for your output file - fill in its sections
-- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
-  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
-  - These guide what you write, but should never appear in the output
-
-**Guardrails**
-- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
-- Always read dependency artifacts before creating a new one
-- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
-- If a change with that name already exists, ask if user wants to continue it or create a new one
-- Verify each artifact file exists after writing before proceeding to next

-description: Sync delta specs from a change to main specs
----
-
-Sync delta specs from a change to main specs.
-
-This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name after `/opsx:sync` (e.g., `/opsx:sync add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have delta specs (under `specs/` directory).
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Resolve change context**
-
-   Run:
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-
-3. **Find delta specs**
-
-   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
-
-   Each delta spec file contains sections like:
-   - `## ADDED Requirements` - New requirements to add
-   - `## MODIFIED Requirements` - Changes to existing requirements
-   - `## REMOVED Requirements` - Requirements to remove
-   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
-
-   If no delta specs found, inform user and stop.
-
-4. **For each delta spec, apply changes to main specs**
-
-   For each repo-local capability delta spec path returned by the CLI:
-
-   a. **Read the delta spec** to understand the intended changes
-
-   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
-
-   c. **Apply changes intelligently**:
-
-      **ADDED Requirements:**
-      - If requirement doesn't exist in main spec → add it
-      - If requirement already exists → update it to match (treat as implicit MODIFIED)
-
-      **MODIFIED Requirements:**
-      - Find the requirement in main spec
-      - Apply the changes - this can be:
-        - Adding new scenarios (don't need to copy existing ones)
-        - Modifying existing scenarios
-        - Changing the requirement description
-      - Preserve scenarios/content not mentioned in the delta
-
-      **REMOVED Requirements:**
-      - Remove the entire requirement block from main spec
-
-      **RENAMED Requirements:**
-      - Find the FROM requirement, rename to TO
-
-   d. **Create new main spec** if capability doesn't exist yet:
-      - Create `openspec/specs/<capability>/spec.md`
-      - Add Purpose section (can be brief, mark as TBD)
-      - Add Requirements section with the ADDED requirements
-
-5. **Show summary**
-
-   After applying all changes, summarize:
-   - Which capabilities were updated
-   - What changes were made (requirements added/modified/removed/renamed)
-
-**Delta Spec Format Reference**
-
-```markdown
-## ADDED Requirements
-
-### Requirement: New Feature
-The system SHALL do something new.
-
-#### Scenario: Basic case
-- **WHEN** user does X
-- **THEN** system does Y
-
-## MODIFIED Requirements
-
-### Requirement: Existing Feature
-#### Scenario: New scenario to add
-- **WHEN** user does A
-- **THEN** system does B
-
-## REMOVED Requirements
-
-### Requirement: Deprecated Feature
-
-## RENAMED Requirements
-
-- FROM: `### Requirement: Old Name`
-- TO: `### Requirement: New Name`
-```
-
-**Key Principle: Intelligent Merging**
-
-Unlike programmatic merging, you can apply **partial updates**:
-- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
-- The delta represents *intent*, not a wholesale replacement
-- Use your judgment to merge changes sensibly
-
-**Output On Success**
-
-```
-## Specs Synced: <change-name>
-
-Updated main specs:
-
-**<capability-1>**:
-- Added requirement: "New Feature"
-- Modified requirement: "Existing Feature" (added 1 scenario)
-
-**<capability-2>**:
-- Created new spec file
-- Added requirement: "Another Feature"
-
-Main specs are now updated. The change remains active - archive when implementation is complete.
-```
-
-**Guardrails**
-- Read both delta and main specs before making changes

-Implement tasks from an OpenSpec change.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **Select the change**
-
-   If a name is provided, use it. Otherwise:
-   - Infer from conversation context if the user mentioned a change
-   - Auto-select if only one active change exists
-   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
-
-   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
-   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
-
-3. **Get apply instructions**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns:
-   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
-   - Progress (total, complete, remaining)
-   - Task list with status
-   - Dynamic instruction based on current state
-
-   **Handle states:**
-   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
-   - If `state: "all_done"`: congratulate, suggest archive
-   - Otherwise: proceed to implementation
-
-4. **Read context files**
-
-   Read every file path listed under `contextFiles` from the apply instructions output.
-   The files depend on the schema being used:
-   - **spec-driven**: proposal, specs, design, tasks
-   - Other schemas: follow the contextFiles from CLI output
-
-5. **Show current progress**
-
-   Display:
-   - Schema being used
-   - Progress: "N/M tasks complete"
-   - Remaining tasks overview
-   - Dynamic instruction from CLI
-
-6. **Implement tasks (loop until done or blocked)**
-
-   For each pending task:
-   - Show which task is being worked on
-   - Make the code changes required
-   - Keep changes minimal and focused
-   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
-   - Continue to next task
-
-   **Pause if:**
-   - Task is unclear → ask for clarification
-   - Implementation reveals a design issue → suggest updating artifacts
-   - Error or blocker encountered → report and wait for guidance
-   - User interrupts
-
-7. **On completion or pause, show status**
-
-   Display:
-   - Tasks completed this session
-   - Overall progress: "N/M tasks complete"
-   - If all done: suggest archive
-   - If paused: explain why and wait for guidance
-
-**Output During Implementation**
-
-```
-## Implementing: <change-name> (schema: <schema-name>)
-
-Working on task 3/7: <task description>
-[...implementation happening...]
-✓ Task complete
-
-Working on task 4/7: <task description>
-[...implementation happening...]
-✓ Task complete
-```
-
-**Output On Completion**
-
-```
-## Implementation Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 7/7 tasks complete ✓
-
-### Completed This Session
-- [x] Task 1
-- [x] Task 2
-...
-
-All tasks complete! Ready to archive this change.
-```
-
-**Output On Pause (Issue Encountered)**
-
-```
-## Implementation Paused
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 4/7 tasks complete
-
-### Issue Encountered
-<description of the issue>
-
-**Options:**
-1. <option 1>
-2. <option 2>
-3. Other approach
-
-What would you like to do?
-```
-
-**Guardrails**
-- Keep going through tasks until done or blocked
-- Always read context files before starting (from the apply instructions output)
-- If task is ambiguous, pause and ask before implementing
-- If implementation reveals issues, pause and suggest artifact updates
-- Keep code changes minimal and scoped to each task
-- Update task checkbox immediately after completing each task
-- Pause on errors, blockers, or unclear requirements - don't guess
-- Use contextFiles from CLI output, don't assume specific file names
-
-**Fluid Workflow Integration**
-
-This skill supports the "actions on a change" model:
-
-- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
-- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show only active changes (not already archived).
-   Include the schema used for each change if available.
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check artifact completion status**
-
-   Run `openspec status --change "<name>" --json` to check artifact completion.
-
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used
-   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
-   - `artifacts`: List of artifacts with their status (`done` or other)
-
-   **If any artifacts are not `done`:**
-   - Display warning listing incomplete artifacts
-   - Use **AskUserQuestion tool** to confirm user wants to proceed
-   - Proceed if user confirms
-
-3. **Check task completion status**
-
-   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
-
-   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
-
-   **If incomplete tasks found:**
-   - Display warning showing count of incomplete tasks
-   - Use **AskUserQuestion tool** to confirm user wants to proceed
-   - Proceed if user confirms
-
-   **If no tasks file exists:** Proceed without task-related warning.
-
-4. **Assess delta spec sync state**
-
-   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
-
-   **If delta specs exist:**
-   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
-   - Determine what changes would be applied (adds, modifications, removals, renames)
-   - Show a combined summary before prompting
-
-   **Prompt options:**
-   - If changes needed: "Sync now (recommended)", "Archive without syncing"
-   - If already synced: "Archive now", "Sync anyway", "Cancel"
-
-   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
-
-5. **Perform the archive**
-
-   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
-   ```bash
-   mkdir -p "<planningHome.changesDir>/archive"
-   ```
-
-   Generate target name using current date: `YYYY-MM-DD-<change-name>`
-
-   **Check if target already exists:**
-   - If yes: Fail with error, suggest renaming existing archive or using different date
-   - If no: Move `changeRoot` to the archive directory
-
-   ```bash
-   mv "<changeRoot>" "<planningHome.changesDir>/archive/YYYY-MM-DD-<name>"
-   ```
-
-6. **Display summary**
-
-   Show archive completion summary including:
-   - Change name
-   - Schema that was used
-   - Archive location
-   - Whether specs were synced (if applicable)
-   - Note about any warnings (incomplete artifacts/tasks)
-
-**Output On Success**
-
-```
-## Archive Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
-**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
-
-All artifacts complete. All tasks complete.
-```
-
-**Guardrails**
-- Always prompt for change selection if not provided
-- Use artifact graph (openspec status --json) for completion checking
-- Don't block archive on warnings - just inform and confirm
-- Preserve .openspec.yaml when moving to archive (it moves with the directory)
-- Show clear summary of what happened
-- If sync is requested, use openspec-sync-specs approach (agent-driven)
-- If delta specs exist, always run the sync assessment and show the combined summary before prompting

-description: Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
-license: MIT
-compatibility: Requires openspec CLI.
-metadata:
-  author: openspec
-  version: "1.0"
-  generatedBy: "1.5.0"
----
-
-Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
-
-**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
-
-**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
----
-
-## The Stance
-
-- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
-- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
-- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
-- **Adaptive** - Follow interesting threads, pivot when new information emerges
-- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
-- **Grounded** - Explore the actual codebase when relevant, don't just theorize
-
----
-
-## What You Might Do
-
-Depending on what the user brings, you might:
-
-**Explore the problem space**
-- Ask clarifying questions that emerge from what they said
-- Challenge assumptions
-- Reframe the problem
-- Find analogies
-
-**Investigate the codebase**
-- Map existing architecture relevant to the discussion
-- Find integration points
-- Identify patterns already in use
-- Surface hidden complexity
-
-**Compare options**
-- Brainstorm multiple approaches
-- Build comparison tables
-- Sketch tradeoffs
-- Recommend a path (if asked)
-
-**Visualize**

-
-## OpenSpec Awareness
-
-You have full context of the OpenSpec system. Use it naturally, don't force it.
-
-### Check for context
-
-At the start, quickly check what exists:
-```bash
-openspec list --json
-```
-
-This tells you:
-- If there are active changes
-- Their names, schemas, and status
-- What the user might be working on
-
-### When no change exists
-
-Think freely. When insights crystallize, you might offer:
-
-- "This feels solid enough to start a change. Want me to create a proposal?"
-- Or keep exploring - no pressure to formalize
-
-### When a change exists
-
-If the user mentions a change or you detect one is relevant:
-
-1. **Resolve and read existing artifacts for context**
-   - Run `openspec status --change "<name>" --json`.
-   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
-   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
-
-2. **Reference them naturally in conversation**
-   - "Your design mentions using Redis, but we just realized SQLite fits better..."
-   - "The proposal scopes this to premium users, but we're now thinking everyone..."
-
-3. **Offer to capture when decisions are made**
-
-    | Insight Type               | Where to Capture               |
-    |----------------------------|--------------------------------|
-    | New requirement discovered | `specs/<capability>/spec.md` |
-    | Requirement changed        | `specs/<capability>/spec.md` |
-    | Design decision made       | `design.md`                  |
-    | Scope changed              | `proposal.md`                |
-    | New work identified        | `tasks.md`                   |
-    | Assumption invalidated     | Relevant artifact              |
-
-   Example offers:
-   - "That's a design decision. Capture it in design.md?"
-   - "This is a new requirement. Add it to specs?"
-   - "This changes scope. Update the proposal?"
-
-4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
-
----
-
-## What You Don't Have To Do
-
-- Follow a script
-- Ask the same questions every time
-- Produce a specific artifact
-- Reach a conclusion
-- Stay on topic if a tangent is valuable
-- Be brief (this is thinking time)
-
----

-## Ending Discovery
-
-There's no required ending. Discovery might:
-
-- **Flow into a proposal**: "Ready to start? I can create a change proposal."
-- **Result in artifact updates**: "Updated design.md with these decisions"
-- **Just provide clarity**: User has what they need, moves on
-- **Continue later**: "We can pick this up anytime"
-
-When it feels like things are crystallizing, you might summarize:
-
-```
-## What We Figured Out
-
-**The problem**: [crystallized understanding]
-
-**The approach**: [if one emerged]
-
-**Open questions**: [if any remain]
-
-**Next steps** (if ready):
-- Create a change proposal
-- Keep exploring: just keep talking
-```
-
-But this summary is optional. Sometimes the thinking IS the value.

-- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
-- **Don't fake understanding** - If something is unclear, dig deeper
-- **Don't rush** - Discovery is thinking time, not task time
-- **Don't force structure** - Let patterns emerge naturally
-- **Don't auto-capture** - Offer to save insights, don't just do it
-- **Do visualize** - A good diagram is worth many paragraphs
-- **Do explore the codebase** - Ground discussions in reality
-- **Do question assumptions** - Including the user's and your own

-   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
-
-   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
-
-2. **Create the change directory**
-   ```bash
-   openspec new change "<name>"
-   ```
-   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
-
-3. **Get the artifact build order**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to get:
-   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
-   - `artifacts`: list of all artifacts with their status and dependencies
-   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
-
-4. **Create artifacts in sequence until apply-ready**
-
-   Use the **TodoWrite tool** to track progress through the artifacts.
-
-   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
-
-   a. **For each artifact that is `ready` (dependencies satisfied)**:
-      - Get instructions:
-        ```bash
-        openspec instructions <artifact-id> --change "<name>" --json
-        ```
-      - The instructions JSON includes:
-        - `context`: Project background (constraints for you - do NOT include in output)
-        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
-        - `template`: The structure to use for your output file
-        - `instruction`: Schema-specific guidance for this artifact type
-        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
-        - `dependencies`: Completed artifacts to read for context
-      - Read any completed dependency files for context
-      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
-      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
-      - Show brief progress: "Created <artifact-id>"
-
-   b. **Continue until all `applyRequires` artifacts are complete**
-      - After creating each artifact, re-run `openspec status --change "<name>" --json`
-      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
-      - Stop when all `applyRequires` artifacts are done
-
-   c. **If an artifact requires user input** (unclear context):
-      - Use **AskUserQuestion tool** to clarify
-      - Then continue with creation
-
-5. **Show final status**
-   ```bash
-   openspec status --change "<name>"
-   ```
-
-**Output**
-
-After completing all artifacts, summarize:
-- Change name and location
-- List of artifacts created with brief descriptions
-- What's ready: "All artifacts created! Ready for implementation."
-- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
-
-**Artifact Creation Guidelines**
-
-- Follow the `instruction` field from `openspec instructions` for each artifact type
-- The schema defines what each artifact should contain - follow it
-- Read dependency artifacts for context before creating new ones
-- Use `template` as the structure for your output file - fill in its sections
-- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
-  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
-  - These guide what you write, but should never appear in the output
-
-**Guardrails**
-- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
-- Always read dependency artifacts before creating a new one
-- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
-- If a change with that name already exists, ask if user wants to continue it or create a new one
-- Verify each artifact file exists after writing before proceeding to next

-name: openspec-sync-specs
-description: Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.
-license: MIT
-compatibility: Requires openspec CLI.
-metadata:
-  author: openspec
-  version: "1.0"
-  generatedBy: "1.5.0"
----
-
-Sync delta specs from a change to main specs.
-
-This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have delta specs (under `specs/` directory).
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Resolve change context**
-
-   Run:
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-
-3. **Find delta specs**
-
-   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
-
-   Each delta spec file contains sections like:
-   - `## ADDED Requirements` - New requirements to add
-   - `## MODIFIED Requirements` - Changes to existing requirements
-   - `## REMOVED Requirements` - Requirements to remove
-   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
-
-   If no delta specs found, inform user and stop.
-
-4. **For each delta spec, apply changes to main specs**
-
-   For each repo-local capability delta spec path returned by the CLI:
-
-   a. **Read the delta spec** to understand the intended changes
-
-   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
-
-   c. **Apply changes intelligently**:
-
-      **ADDED Requirements:**
-      - If requirement doesn't exist in main spec → add it
-      - If requirement already exists → update it to match (treat as implicit MODIFIED)
-
-      **MODIFIED Requirements:**
-      - Find the requirement in main spec
-      - Apply the changes - this can be:
-        - Adding new scenarios (don't need to copy existing ones)
-        - Modifying existing scenarios
-        - Changing the requirement description
-      - Preserve scenarios/content not mentioned in the delta
-
-      **REMOVED Requirements:**
-      - Remove the entire requirement block from main spec
-
-      **RENAMED Requirements:**
-      - Find the FROM requirement, rename to TO
-
-   d. **Create new main spec** if capability doesn't exist yet:
-      - Create `openspec/specs/<capability>/spec.md`
-      - Add Purpose section (can be brief, mark as TBD)
-      - Add Requirements section with the ADDED requirements
-
-5. **Show summary**
-
-   After applying all changes, summarize:
-   - Which capabilities were updated
-   - What changes were made (requirements added/modified/removed/renamed)
-
-**Delta Spec Format Reference**
-
-```markdown
-## ADDED Requirements
-
-### Requirement: New Feature
-The system SHALL do something new.
-
-#### Scenario: Basic case
-- **WHEN** user does X
-- **THEN** system does Y
-
-## MODIFIED Requirements
-
-### Requirement: Existing Feature
-#### Scenario: New scenario to add
-- **WHEN** user does A
-- **THEN** system does B
-
-## REMOVED Requirements
-
-### Requirement: Deprecated Feature
-
-## RENAMED Requirements
-
-- FROM: `### Requirement: Old Name`
-- TO: `### Requirement: New Name`
-```
-
-**Key Principle: Intelligent Merging**
-
-Unlike programmatic merging, you can apply **partial updates**:
-- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
-- The delta represents *intent*, not a wholesale replacement
-- Use your judgment to merge changes sensibly
-
-**Output On Success**
-
-```
-## Specs Synced: <change-name>
-
-Updated main specs:
-
-**<capability-1>**:
-- Added requirement: "New Feature"
-- Modified requirement: "Existing Feature" (added 1 scenario)
-
-**<capability-2>**:
-- Created new spec file
-- Added requirement: "Another Feature"
-
-Main specs are now updated. The change remains active - archive when implementation is complete.
-```
-
-**Guardrails**
-- Read both delta and main specs before making changes
-- Preserve existing content not mentioned in delta
-- If something is unclear, ask for clarification
-- Show what you're changing as you go
-- The operation should be idempotent - running twice should give same result

-# Plan: Create AGENTS.md for Animius
-
-## Goal
-Create a compact `AGENTS.md` at the repository root that gives future AI agents the high-signal, repo-specific context they need to work effectively.
-
-## Content
-
-### Build & Run Commands
-- Debug build: `./gradlew assembleDebug`
-- Release build: `./gradlew assembleRelease` (requires env vars)
-- Unit tests: `./gradlew test`
-- Single test class: `./gradlew :app:testDebugUnitTest --tests "com.lanlinju.animius.FooTest"`
-- No lint, typecheck, or formatter configured — skip lint/typecheck steps
-- JVM target: 17, AGP 8.11.0, Kotlin 2.2.0
-
-### Secrets & Environment
-- `DANDANPLAY_APP_ID` and `DANDANPLAY_APP_SECRET` read from env vars (not local.properties) at build time into BuildConfig
-- Signing keys (`KEY_STORE_PASSWORD`, `KEY_ALIAS`, `KEY_PASSWORD`) also from env vars
-- Without these env vars, build succeeds but danmaku features are non-functional
-
-### Module Structure
-- `:app` — main application (MVVM + Clean Architecture)
-- `:video-player` — Compose Media3 ExoPlayer wrapper
-- `:download` — download engine (OkHttp, supports M3U8/range)
-- `:danmaku` — Compose danmaku overlay engine
-
-### Architecture Quick Reference
-- Source code under `app/src/main/java/com/lanlinju/animius/`
-- Layers: `data/` → `domain/` → `presentation/`
-- Multi-source anime scraping via `AnimeSource` interface + `SourceHolder` singleton (11 sources, enum `SourceMode`)
-- DI: Hilt with `@HiltAndroidApp`, `@AndroidEntryPoint`, `@HiltViewModel`
-- Navigation: type-safe Compose Navigation with `@Serializable` sealed class routes
-- State: `MutableStateFlow<Resource<T>>` pattern, no MVI
-- Domain model conversions are extension functions on data classes (not separate mapper files)
-
-### Key Conventions
-- Screens: `{Feature}Screen.kt` + `{Feature}ViewModel.kt` in `presentation/screen/{feature}/`
-- DTOs: `*Bean.kt` suffix
-- Entities: `*Entity.kt`, DAOs: `*Dao.kt`
-- Sources: `{Name}Source.kt` in `data/remote/parse/`
-- Images via Coil, JSON via kotlinx.serialization
-- Room schema exported to `app/schemas/` via KSP
-
-### Gotchas
-- No linting/static analysis configured (no detekt, ktlint, lint.xml)
-- No lockfiles — dependency resolution not reproducible
-- Room uses `fallbackToDestructiveMigration()` — schema changes wipe data
-- Release build has R8 minification — keep rules in `app/proguard-rules.pro`
-- `SourceMode` enum kept in ProGuard (serialized to SharedPreferences as string)
-- WebView-based sources (Xifan, Ntdm, Gugufan) need special handling via `WebViewUtil`
-
-### CI
-- GitHub Actions on push to `main`/`feat-compat-tv`, PRs, and tags
-- CI only builds — no tests run in CI
-- Release workflow triggers on `v*` tags
-
-## File to create
-- `E:\Github\Anime\Animius\AGENTS.md`
-
-## Verification
-- Read the created file to confirm content accuracy
-- Verify commands match CI workflow and build.gradle.kts

-- Card border颜色统一为#BCC0C8（深色浅色一致）
-- Week页面TopAppBar标题区域改为圆角矩形焦点背景
-- Home页面站源文本移除clickable，不再可聚焦
-- 详情页标签改为非交互Box，不再可聚焦
-```
-
-## 问题
-
-1. **WeekScreen TabRow** (`WeekScreen.kt:165-175`): Material3 `Tab` 指示器是底部线条，聚焦时无圆角矩形背景
-2. **HomeScreen 站源文本** (`HomeScreen.kt:413-427`): 纯 `Text`，无焦点样式，点击无反应
-3. **HomeScreen GridLayoutTabs** (`HomeScreen.kt:224-230`): 自定义 `Tab` 用 `Surface(RoundedCornerShape(11.dp))`，聚焦有背景但非统一风格
-
-## 方案
-
-### 核心思路
-
-Material3 `Tab` 内置 onClick + focus，但指示器是线条不是圆角矩形。用 `Surface(onClick, shape, color)` 包一层即可获得圆角矩形背景 + 内置 focusable，无需单独建组件。
-
-### 1. 修改 WeekScreen (`WeekScreen.kt:165-175`)
-
-**改前:**
-```kotlin
-TabRow(selectedTabIndex = pagerState.currentPage) {
-    TABS.forEachIndexed { index, title ->
-        Tab(text = { Text(text = title) }, ...)
-    }
-}
-```
-
-**改后:**
-```kotlin
-Row(
-    modifier = Modifier.fillMaxWidth().padding(horizontal = 16.dp),
-    horizontalArrangement = Arrangement.spacedBy(8.dp),
-) {
-    TABS.forEachIndexed { index, title ->
-        Surface(
-            onClick = { scope.launch { pagerState.scrollToPage(index) } },
-            shape = RoundedCornerShape(20.dp),
-            color = if (pagerState.currentPage == index)
-                MaterialTheme.colorScheme.primary
-            else Color.Transparent,
-            contentColor = if (pagerState.currentPage == index)
-                MaterialTheme.colorScheme.onPrimary
-            else MaterialTheme.colorScheme.onSurface,
-        ) {
-            Text(
-                text = title,
-                modifier = Modifier.padding(horizontal = 16.dp, vertical = 8.dp),
-            )
-        }
-    }
-}
-```
-
-### 2. 修改 HomeScreen GridLayoutTabs (`HomeScreen.kt:224-230`)
-
-将自定义 `Tab` 的 `RoundedCornerShape(11.dp)` 改为 `RoundedCornerShape(20.dp)` 统一风格。
-
-### 3. 修改 HomeScreen 站源选择器 (`HomeScreen.kt:413-427`)
-
-将纯 `Text` 改为 `Surface(onClick)` + `DropdownMenu`，点击弹出站源列表。
-
-## 修改文件
-
-| 文件 | 改动 |
-|------|------|
-| `app/.../screen/week/WeekScreen.kt:165-175` | `TabRow` → `Row` + `Surface` |
-| `app/.../screen/home/HomeScreen.kt:224-230` | `RoundedCornerShape(11.dp)` → `20.dp` |
-| `app/.../screen/home/HomeScreen.kt:266-289` | 自定义 `Tab` 的 shape 统一 |
-| `app/.../screen/home/HomeScreen.kt:413-427` | 站源 `Text` → `Surface` + `DropdownMenu` |
-
-## 验证
-
-1. `./gradlew assembleDebug` 编译通过
-2. D-pad 测试：
-   - Week 页面 Tab 聚焦显示圆角矩形背景
-   - Home 页面 Tab 聚焦显示圆角矩形背景
-   - Home 站源可聚焦，点击弹出列表

-description: Implement tasks from an OpenSpec change (Experimental)
----
-
-Implement tasks from an OpenSpec change.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name (e.g., `/opsx-apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **Select the change**
-
-   If a name is provided, use it. Otherwise:
-   - Infer from conversation context if the user mentioned a change
-   - Auto-select if only one active change exists
-   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
-
-   Always announce: "Using change: <name>" and how to override (e.g., `/opsx-apply <other>`).
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
-   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
-
-3. **Get apply instructions**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns:
-   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema)
-   - Progress (total, complete, remaining)
-   - Task list with status
-   - Dynamic instruction based on current state
-
-   **Handle states:**
-   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx-continue`
-   - If `state: "all_done"`: congratulate, suggest archive
-   - Otherwise: proceed to implementation
-
-4. **Read context files**
-
-   Read every file path listed under `contextFiles` from the apply instructions output.
-   The files depend on the schema being used:
-   - **spec-driven**: proposal, specs, design, tasks
-   - Other schemas: follow the contextFiles from CLI output
-
-5. **Show current progress**
-
-   Display:
-   - Schema being used
-   - Progress: "N/M tasks complete"
-   - Remaining tasks overview
-   - Dynamic instruction from CLI
-
-6. **Implement tasks (loop until done or blocked)**
-
-   For each pending task:
-   - Show which task is being worked on
-   - Make the code changes required
-   - Keep changes minimal and focused
-   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
-   - Continue to next task
-
-   **Pause if:**
-   - Task is unclear → ask for clarification
-   - Implementation reveals a design issue → suggest updating artifacts
-   - Error or blocker encountered → report and wait for guidance
-   - User interrupts
-
-7. **On completion or pause, show status**
-
-   Display:
-   - Tasks completed this session
-   - Overall progress: "N/M tasks complete"
-   - If all done: suggest archive
-   - If paused: explain why and wait for guidance
-
-**Output During Implementation**
-
-```
-## Implementing: <change-name> (schema: <schema-name>)
-
-Working on task 3/7: <task description>
-[...implementation happening...]
-✓ Task complete
-
-Working on task 4/7: <task description>
-[...implementation happening...]
-✓ Task complete
-```
-
-**Output On Completion**
-
-```
-## Implementation Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 7/7 tasks complete ✓
-
-### Completed This Session
-- [x] Task 1
-- [x] Task 2
-...
-
-All tasks complete! You can archive this change with `/opsx-archive`.
-```
-
-**Output On Pause (Issue Encountered)**
-
-```
-## Implementation Paused
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 4/7 tasks complete
-
-### Issue Encountered
-<description of the issue>
-
-**Options:**
-1. <option 1>
-2. <option 2>
-3. Other approach
-
-What would you like to do?
-```
-
-**Guardrails**
-- Keep going through tasks until done or blocked
-- Always read context files before starting (from the apply instructions output)
-- If task is ambiguous, pause and ask before implementing
-- If implementation reveals issues, pause and suggest artifact updates
-- Keep code changes minimal and scoped to each task
-- Update task checkbox immediately after completing each task
-- Pause on errors, blockers, or unclear requirements - don't guess
-- Use contextFiles from CLI output, don't assume specific file names
-
-**Fluid Workflow Integration**
-
-This skill supports the "actions on a change" model:
-
-- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
-- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.

-   Show only active changes (not already archived).
-   Include the schema used for each change if available.
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check artifact completion status**
-
-   Run `openspec status --change "<name>" --json` to check artifact completion.
-
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used
-   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
-   - `artifacts`: List of artifacts with their status (`done` or other)
-
-   **If any artifacts are not `done`:**
-   - Display warning listing incomplete artifacts
-   - Prompt user for confirmation to continue
-   - Proceed if user confirms
-
-3. **Check task completion status**
-
-   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
-
-   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
-
-   **If incomplete tasks found:**
-   - Display warning showing count of incomplete tasks
-   - Prompt user for confirmation to continue
-   - Proceed if user confirms
-
-   **If no tasks file exists:** Proceed without task-related warning.
-
-4. **Assess delta spec sync state**
-
-   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
-
-   **If delta specs exist:**
-   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
-   - Determine what changes would be applied (adds, modifications, removals, renames)
-   - Show a combined summary before prompting
-
-   **Prompt options:**
-   - If changes needed: "Sync now (recommended)", "Archive without syncing"
-   - If already synced: "Archive now", "Sync anyway", "Cancel"
-
-   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
-
-5. **Perform the archive**
-
-   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
-   ```bash
-   mkdir -p "<planningHome.changesDir>/archive"
-   ```
-
-   Generate target name using current date: `YYYY-MM-DD-<change-name>`
-
-   **Check if target already exists:**
-   - If yes: Fail with error, suggest renaming existing archive or using different date
-   - If no: Move `changeRoot` to the archive directory
-
-   ```bash
-   mv "<changeRoot>" "<planningHome.changesDir>/archive/YYYY-MM-DD-<name>"
-   ```
-
-6. **Display summary**
-
-   Show archive completion summary including:
-   - Change name
-   - Schema that was used
-   - Archive location
-   - Spec sync status (synced / sync skipped / no delta specs)
-   - Note about any warnings (incomplete artifacts/tasks)
-
-**Output On Success**
-
-```
-## Archive Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/

-**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
-**Specs:** Sync skipped (user chose to skip)
-
-**Warnings:**
-- Archived with 2 incomplete artifacts
-- Archived with 3 incomplete tasks
-- Delta spec sync was skipped (user chose to skip)
-
-Review the archive if this was not intentional.
-```
-
-**Output On Error (Archive Exists)**
-
-```
-## Archive Failed
-
-**Change:** <change-name>
-**Target:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
-
-Target archive directory already exists.
-
-**Options:**
-1. Rename the existing archive
-2. Delete the existing archive if it's a duplicate
-3. Wait until a different date to archive
-```
-
-**Guardrails**
-- Always prompt for change selection if not provided
-- Use artifact graph (openspec status --json) for completion checking
-- Don't block archive on warnings - just inform and confirm
-- Preserve .openspec.yaml when moving to archive (it moves with the directory)
-- Show clear summary of what happened
-- If sync is requested, use the Skill tool to invoke `openspec-sync-specs` (agent-driven)
-- If delta specs exist, always run the sync assessment and show the combined summary before prompting

-description: Enter explore mode - think through ideas, investigate problems, clarify requirements
----
-
-Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
-
-**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
-
-**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: The argument after `/opsx-explore` is whatever the user wants to think about. Could be:
-- A vague idea: "real-time collaboration"
-- A specific problem: "the auth system is getting unwieldy"
-- A change name: "add-dark-mode" (to explore in context of that change)
-- A comparison: "postgres vs sqlite for this"
-- Nothing (just enter explore mode)
-
----
-
-## The Stance
-
-- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
-- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
-- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
-- **Adaptive** - Follow interesting threads, pivot when new information emerges
-- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
-- **Grounded** - Explore the actual codebase when relevant, don't just theorize
-
----
-
-## What You Might Do
-
-Depending on what the user brings, you might:
-
-**Explore the problem space**
-- Ask clarifying questions that emerge from what they said
-- Challenge assumptions
-- Reframe the problem
-- Find analogies
-
-**Investigate the codebase**
-- Map existing architecture relevant to the discussion
-- Find integration points
-- Identify patterns already in use
-- Surface hidden complexity
-
-**Compare options**
-- Brainstorm multiple approaches
-- Build comparison tables
-- Sketch tradeoffs
-- Recommend a path (if asked)
-
-**Visualize**
-```

-
-## OpenSpec Awareness
-
-You have full context of the OpenSpec system. Use it naturally, don't force it.
-
-### Check for context
-
-At the start, quickly check what exists:
-```bash
-openspec list --json
-```
-
-This tells you:
-- If there are active changes
-- Their names, schemas, and status
-- What the user might be working on
-
-If the user mentioned a specific change name, read its artifacts for context.
-
-### When no change exists
-
-Think freely. When insights crystallize, you might offer:
-
-- "This feels solid enough to start a change. Want me to create a proposal?"
-- Or keep exploring - no pressure to formalize
-
-### When a change exists
-
-If the user mentions a change or you detect one is relevant:
-
-1. **Resolve and read existing artifacts for context**
-   - Run `openspec status --change "<name>" --json`.
-   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
-   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
-
-2. **Reference them naturally in conversation**
-   - "Your design mentions using Redis, but we just realized SQLite fits better..."
-   - "The proposal scopes this to premium users, but we're now thinking everyone..."
-
-3. **Offer to capture when decisions are made**
-
-    | Insight Type               | Where to Capture               |
-    |----------------------------|--------------------------------|
-    | New requirement discovered | `specs/<capability>/spec.md` |
-    | Requirement changed        | `specs/<capability>/spec.md` |
-    | Design decision made       | `design.md`                  |
-    | Scope changed              | `proposal.md`                |
-    | New work identified        | `tasks.md`                   |
-    | Assumption invalidated     | Relevant artifact              |
-
-   Example offers:
-   - "That's a design decision. Capture it in design.md?"
-   - "This is a new requirement. Add it to specs?"
-   - "This changes scope. Update the proposal?"
-
-4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
-
----
-
-## What You Don't Have To Do
-
-- Follow a script
-- Ask the same questions every time
-- Produce a specific artifact
-- Reach a conclusion
-- Stay on topic if a tangent is valuable
-- Be brief (this is thinking time)
-
----
-
-## Ending Discovery
-
-There's no required ending. Discovery might:
-
-- **Flow into a proposal**: "Ready to start? I can create a change proposal."
-- **Result in artifact updates**: "Updated design.md with these decisions"
-- **Just provide clarity**: User has what they need, moves on
-- **Continue later**: "We can pick this up anytime"
-
-When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
-
----
-
-## Guardrails
-
-- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
-- **Don't fake understanding** - If something is unclear, dig deeper
-- **Don't rush** - Discovery is thinking time, not task time
-- **Don't force structure** - Let patterns emerge naturally
-- **Don't auto-capture** - Offer to save insights, don't just do it
-- **Do visualize** - A good diagram is worth many paragraphs
-- **Do explore the codebase** - Ground discussions in reality
-- **Do question assumptions** - Including the user's and your own

-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: The argument after `/opsx-propose` is the change name (kebab-case), OR a description of what the user wants to build.
-
-**Steps**
-
-1. **If no input provided, ask what they want to build**
-
-   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
-   > "What change do you want to work on? Describe what you want to build or fix."
-
-   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
-
-   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
-
-2. **Create the change directory**
-   ```bash
-   openspec new change "<name>"
-   ```
-   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
-
-3. **Get the artifact build order**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to get:
-   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
-   - `artifacts`: list of all artifacts with their status and dependencies
-   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
-
-4. **Create artifacts in sequence until apply-ready**
-
-   Use the **TodoWrite tool** to track progress through the artifacts.
-
-   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
-
-   a. **For each artifact that is `ready` (dependencies satisfied)**:
-      - Get instructions:
-        ```bash
-        openspec instructions <artifact-id> --change "<name>" --json
-        ```
-      - The instructions JSON includes:
-        - `context`: Project background (constraints for you - do NOT include in output)
-        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
-        - `template`: The structure to use for your output file
-        - `instruction`: Schema-specific guidance for this artifact type
-        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
-        - `dependencies`: Completed artifacts to read for context
-      - Read any completed dependency files for context
-      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
-      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
-      - Show brief progress: "Created <artifact-id>"
-
-   b. **Continue until all `applyRequires` artifacts are complete**
-      - After creating each artifact, re-run `openspec status --change "<name>" --json`
-      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
-      - Stop when all `applyRequires` artifacts are done
-
-   c. **If an artifact requires user input** (unclear context):
-      - Use **AskUserQuestion tool** to clarify
-      - Then continue with creation
-
-5. **Show final status**
-   ```bash
-   openspec status --change "<name>"
-   ```
-
-**Output**
-
-After completing all artifacts, summarize:
-- Change name and location
-- List of artifacts created with brief descriptions
-- What's ready: "All artifacts created! Ready for implementation."
-- Prompt: "Run `/opsx-apply` to start implementing."
-
-**Artifact Creation Guidelines**
-
-- Follow the `instruction` field from `openspec instructions` for each artifact type
-- The schema defines what each artifact should contain - follow it
-- Read dependency artifacts for context before creating new ones
-- Use `template` as the structure for your output file - fill in its sections
-- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
-  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
-  - These guide what you write, but should never appear in the output
-
-**Guardrails**
-- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
-- Always read dependency artifacts before creating a new one
-- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
-- If a change with that name already exists, ask if user wants to continue it or create a new one
-- Verify each artifact file exists after writing before proceeding to next

-description: Sync delta specs from a change to main specs
----
-
-Sync delta specs from a change to main specs.
-
-This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name after `/opsx-sync` (e.g., `/opsx-sync add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have delta specs (under `specs/` directory).
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Resolve change context**
-
-   Run:
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-
-3. **Find delta specs**
-
-   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
-
-   Each delta spec file contains sections like:
-   - `## ADDED Requirements` - New requirements to add
-   - `## MODIFIED Requirements` - Changes to existing requirements
-   - `## REMOVED Requirements` - Requirements to remove
-   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
-
-   If no delta specs found, inform user and stop.
-
-4. **For each delta spec, apply changes to main specs**
-
-   For each repo-local capability delta spec path returned by the CLI:
-
-   a. **Read the delta spec** to understand the intended changes
-
-   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
-
-   c. **Apply changes intelligently**:
-
-      **ADDED Requirements:**
-      - If requirement doesn't exist in main spec → add it
-      - If requirement already exists → update it to match (treat as implicit MODIFIED)
-
-      **MODIFIED Requirements:**
-      - Find the requirement in main spec
-      - Apply the changes - this can be:
-        - Adding new scenarios (don't need to copy existing ones)
-        - Modifying existing scenarios
-        - Changing the requirement description
-      - Preserve scenarios/content not mentioned in the delta
-
-      **REMOVED Requirements:**
-      - Remove the entire requirement block from main spec
-
-      **RENAMED Requirements:**
-      - Find the FROM requirement, rename to TO
-
-   d. **Create new main spec** if capability doesn't exist yet:
-      - Create `openspec/specs/<capability>/spec.md`
-      - Add Purpose section (can be brief, mark as TBD)
-      - Add Requirements section with the ADDED requirements
-
-5. **Show summary**
-
-   After applying all changes, summarize:
-   - Which capabilities were updated
-   - What changes were made (requirements added/modified/removed/renamed)
-
-**Delta Spec Format Reference**
-
-```markdown
-## ADDED Requirements
-
-### Requirement: New Feature
-The system SHALL do something new.
-
-#### Scenario: Basic case
-- **WHEN** user does X
-- **THEN** system does Y
-
-## MODIFIED Requirements
-
-### Requirement: Existing Feature
-#### Scenario: New scenario to add
-- **WHEN** user does A
-- **THEN** system does B
-
-## REMOVED Requirements
-
-### Requirement: Deprecated Feature
-
-## RENAMED Requirements
-
-- FROM: `### Requirement: Old Name`
-- TO: `### Requirement: New Name`
-```
-
-**Key Principle: Intelligent Merging**
-
-Unlike programmatic merging, you can apply **partial updates**:
-- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
-- The delta represents *intent*, not a wholesale replacement
-- Use your judgment to merge changes sensibly
-
-**Output On Success**
-
-```
-## Specs Synced: <change-name>
-
-Updated main specs:
-
-**<capability-1>**:
-- Added requirement: "New Feature"
-- Modified requirement: "Existing Feature" (added 1 scenario)
-
-**<capability-2>**:
-- Created new spec file
-- Added requirement: "Another Feature"
-
-Main specs are now updated. The change remains active - archive when implementation is complete.
-```
-
-**Guardrails**
-- Read both delta and main specs before making changes
-- Preserve existing content not mentioned in delta
-- If something is unclear, ask for clarification
-- Show what you're changing as you go
-- The operation should be idempotent - running twice should give same result

-# Fix: EpisodeListControl click not responding
-
-## Problem
-EpisodeListControl "reverse list" and "more episodes" buttons stopped responding to clicks after adding background + focus inverse color effect.
-
-## Root cause
-The modifier chain used `.let { mod -> if (isAndroidTV) mod.onFocusChanged{}.focusable() else mod }` before `.clickable()`. This appears to interfere with `clickable`'s internal focus/click handling — `clickable` already adds `focusable()` internally, and the explicit one before it may conflict.
-
-## Fix
-Replace the conditional `.let{}` with direct `.onFocusChanged{}`:
-- Remove the `.let{}` block
-- Remove the explicit `.focusable()` (redundant — `clickable` handles it)
-- Use `.onFocusChanged {}` directly at the same position (safe observer, no side effects on phone/TV)
-- Keep the `isAndroidTV` guard inside the lambda to only update state on TV
-
-## Modified modifier chain (phone and TV same):
-`clip -> background -> onFocusChanged -> clickable -> padding`
-
-## Build & Install
-- `.\gradlew assembleDebug`
-- `adb install -r app/build/outputs/apk/debug/Animius-v1.3.5-debug.apk`

-
-Implement tasks from an OpenSpec change.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **Select the change**
-
-   If a name is provided, use it. Otherwise:
-   - Infer from conversation context if the user mentioned a change
-   - Auto-select if only one active change exists
-   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
-
-   Always announce: "Using change: <name>" and how to override (e.g., `/opsx-apply <other>`).
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - `planningHome`, `changeRoot`, and `actionContext`: planning scope and edit constraints
-   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
-
-3. **Get apply instructions**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns:
-   - `contextFiles`: artifact ID -> array of concrete file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
-   - Progress (total, complete, remaining)
-   - Task list with status
-   - Dynamic instruction based on current state
-
-   **Handle states:**
-   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
-   - If `state: "all_done"`: congratulate, suggest archive
-   - Otherwise: proceed to implementation
-
-4. **Read context files**
-
-   Read every file path listed under `contextFiles` from the apply instructions output.
-   The files depend on the schema being used:
-   - **spec-driven**: proposal, specs, design, tasks
-   - Other schemas: follow the contextFiles from CLI output
-
-5. **Show current progress**
-
-   Display:
-   - Schema being used
-   - Progress: "N/M tasks complete"
-   - Remaining tasks overview
-   - Dynamic instruction from CLI
-
-6. **Implement tasks (loop until done or blocked)**
-
-   For each pending task:
-   - Show which task is being worked on
-   - Make the code changes required
-   - Keep changes minimal and focused
-   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
-   - Continue to next task
-
-   **Pause if:**
-   - Task is unclear → ask for clarification
-   - Implementation reveals a design issue → suggest updating artifacts
-   - Error or blocker encountered → report and wait for guidance
-   - User interrupts
-
-7. **On completion or pause, show status**
-
-   Display:
-   - Tasks completed this session
-   - Overall progress: "N/M tasks complete"
-   - If all done: suggest archive
-   - If paused: explain why and wait for guidance
-
-**Output During Implementation**
-
-```
-## Implementing: <change-name> (schema: <schema-name>)
-
-Working on task 3/7: <task description>
-[...implementation happening...]
-✓ Task complete
-
-Working on task 4/7: <task description>
-[...implementation happening...]
-✓ Task complete
-```
-
-**Output On Completion**
-
-```
-## Implementation Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 7/7 tasks complete ✓
-
-### Completed This Session
-- [x] Task 1
-- [x] Task 2
-...
-
-All tasks complete! Ready to archive this change.
-```
-
-**Output On Pause (Issue Encountered)**
-
-```
-## Implementation Paused
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 4/7 tasks complete
-
-### Issue Encountered
-<description of the issue>
-
-**Options:**
-1. <option 1>
-2. <option 2>
-3. Other approach
-
-What would you like to do?
-```
-
-**Guardrails**
-- Keep going through tasks until done or blocked
-- Always read context files before starting (from the apply instructions output)
-- If task is ambiguous, pause and ask before implementing
-- If implementation reveals issues, pause and suggest artifact updates
-- Keep code changes minimal and scoped to each task
-- Update task checkbox immediately after completing each task
-- Pause on errors, blockers, or unclear requirements - don't guess
-- Use contextFiles from CLI output, don't assume specific file names
-
-**Fluid Workflow Integration**
-
-This skill supports the "actions on a change" model:
-
-- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
-- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

-
-Archive a completed change in the experimental workflow.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show only active changes (not already archived).
-   Include the schema used for each change if available.
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check artifact completion status**
-
-   Run `openspec status --change "<name>" --json` to check artifact completion.
-
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used
-   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context
-   - `artifacts`: List of artifacts with their status (`done` or other)
-
-   **If any artifacts are not `done`:**
-   - Display warning listing incomplete artifacts
-   - Use **AskUserQuestion tool** to confirm user wants to proceed
-   - Proceed if user confirms
-
-3. **Check task completion status**
-
-   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
-
-   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
-
-   **If incomplete tasks found:**
-   - Display warning showing count of incomplete tasks
-   - Use **AskUserQuestion tool** to confirm user wants to proceed
-   - Proceed if user confirms
-
-   **If no tasks file exists:** Proceed without task-related warning.
-
-4. **Assess delta spec sync state**
-
-   Use `artifactPaths.specs.existingOutputPaths` from status JSON to check for delta specs. If none exist, proceed without sync prompt.
-
-   **If delta specs exist:**
-   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
-   - Determine what changes would be applied (adds, modifications, removals, renames)
-   - Show a combined summary before prompting
-
-   **Prompt options:**
-   - If changes needed: "Sync now (recommended)", "Archive without syncing"
-   - If already synced: "Archive now", "Sync anyway", "Cancel"
-
-   If user chooses sync, use Task tool (subagent_type: "general-purpose", prompt: "Use Skill tool to invoke openspec-sync-specs for change '<name>'. Delta spec analysis: <include the analyzed delta spec summary>"). Proceed to archive regardless of choice.
-
-5. **Perform the archive**
-
-   Create an `archive` directory under `planningHome.changesDir` if it doesn't exist:
-   ```bash
-   mkdir -p "<planningHome.changesDir>/archive"
-   ```
-
-   Generate target name using current date: `YYYY-MM-DD-<change-name>`
-
-   **Check if target already exists:**
-   - If yes: Fail with error, suggest renaming existing archive or using different date
-   - If no: Move `changeRoot` to the archive directory
-
-   ```bash
-   mv "<changeRoot>" "<planningHome.changesDir>/archive/YYYY-MM-DD-<name>"
-   ```
-
-6. **Display summary**
-
-   Show archive completion summary including:
-   - Change name
-   - Schema that was used
-   - Archive location
-   - Whether specs were synced (if applicable)
-   - Note about any warnings (incomplete artifacts/tasks)
-
-**Output On Success**
-
-```
-## Archive Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** the archive path derived from `planningHome.changesDir`/YYYY-MM-DD-<name>/
-**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
-
-All artifacts complete. All tasks complete.
-```
-
-**Guardrails**
-- Always prompt for change selection if not provided
-- Use artifact graph (openspec status --json) for completion checking
-- Don't block archive on warnings - just inform and confirm
-- Preserve .openspec.yaml when moving to archive (it moves with the directory)
-- Show clear summary of what happened
-- If sync is requested, use openspec-sync-specs approach (agent-driven)
-- If delta specs exist, always run the sync assessment and show the combined summary before prompting

-description: Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
-license: MIT
-compatibility: Requires openspec CLI.
-metadata:
-  author: openspec
-  version: "1.0"
-  generatedBy: "1.5.0"
----
-
-Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
-
-**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first and create a change proposal. You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
-
-**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
----
-
-## The Stance
-
-- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
-- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
-- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
-- **Adaptive** - Follow interesting threads, pivot when new information emerges
-- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
-- **Grounded** - Explore the actual codebase when relevant, don't just theorize
-
----
-
-## What You Might Do
-
-Depending on what the user brings, you might:
-
-**Explore the problem space**
-- Ask clarifying questions that emerge from what they said
-- Challenge assumptions
-- Reframe the problem
-- Find analogies
-
-**Investigate the codebase**
-- Map existing architecture relevant to the discussion
-- Find integration points
-- Identify patterns already in use
-- Surface hidden complexity
-
-**Compare options**
-- Brainstorm multiple approaches
-- Build comparison tables
-- Sketch tradeoffs
-- Recommend a path (if asked)
-
-**Visualize**

-
-## OpenSpec Awareness
-
-You have full context of the OpenSpec system. Use it naturally, don't force it.
-
-### Check for context
-
-At the start, quickly check what exists:
-```bash
-openspec list --json
-```
-
-This tells you:
-- If there are active changes
-- Their names, schemas, and status
-- What the user might be working on
-
-### When no change exists
-
-Think freely. When insights crystallize, you might offer:
-
-- "This feels solid enough to start a change. Want me to create a proposal?"
-- Or keep exploring - no pressure to formalize
-
-### When a change exists
-
-If the user mentions a change or you detect one is relevant:
-
-1. **Resolve and read existing artifacts for context**
-   - Run `openspec status --change "<name>" --json`.
-   - Use `changeRoot`, `artifactPaths`, and `actionContext` from the status JSON.
-   - Read existing files from `artifactPaths.<artifact>.existingOutputPaths`.
-
-2. **Reference them naturally in conversation**
-   - "Your design mentions using Redis, but we just realized SQLite fits better..."
-   - "The proposal scopes this to premium users, but we're now thinking everyone..."
-
-3. **Offer to capture when decisions are made**
-
-    | Insight Type               | Where to Capture               |
-    |----------------------------|--------------------------------|
-    | New requirement discovered | `specs/<capability>/spec.md` |
-    | Requirement changed        | `specs/<capability>/spec.md` |
-    | Design decision made       | `design.md`                  |
-    | Scope changed              | `proposal.md`                |
-    | New work identified        | `tasks.md`                   |
-    | Assumption invalidated     | Relevant artifact              |
-
-   Example offers:
-   - "That's a design decision. Capture it in design.md?"
-   - "This is a new requirement. Add it to specs?"
-   - "This changes scope. Update the proposal?"
-
-4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
-
----
-
-## What You Don't Have To Do
-
-- Follow a script
-- Ask the same questions every time
-- Produce a specific artifact
-- Reach a conclusion
-- Stay on topic if a tangent is valuable
-- Be brief (this is thinking time)
-

-## Ending Discovery
-
-There's no required ending. Discovery might:
-
-- **Flow into a proposal**: "Ready to start? I can create a change proposal."
-- **Result in artifact updates**: "Updated design.md with these decisions"
-- **Just provide clarity**: User has what they need, moves on
-- **Continue later**: "We can pick this up anytime"
-
-When it feels like things are crystallizing, you might summarize:
-
-```
-## What We Figured Out
-
-**The problem**: [crystallized understanding]
-
-**The approach**: [if one emerged]
-
-**Open questions**: [if any remain]
-
-**Next steps** (if ready):
-- Create a change proposal
-- Keep exploring: just keep talking
-```
-
-But this summary is optional. Sometimes the thinking IS the value.

-## Guardrails
-
-- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
-- **Don't fake understanding** - If something is unclear, dig deeper
-- **Don't rush** - Discovery is thinking time, not task time
-- **Don't force structure** - Let patterns emerge naturally
-- **Don't auto-capture** - Offer to save insights, don't just do it
-- **Do visualize** - A good diagram is worth many paragraphs
-- **Do explore the codebase** - Ground discussions in reality
-- **Do question assumptions** - Including the user's and your own

Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
-
-**Steps**
-
-1. **If no clear input provided, ask what they want to build**
-
-   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
-   > "What change do you want to work on? Describe what you want to build or fix."
-
-   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
-
-   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
-
-2. **Create the change directory**
-   ```bash
-   openspec new change "<name>"
-   ```
-   This creates a scaffolded change in the planning home resolved by the CLI with `.openspec.yaml`.
-
-3. **Get the artifact build order**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to get:
-   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
-   - `artifacts`: list of all artifacts with their status and dependencies
-   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.
-
-4. **Create artifacts in sequence until apply-ready**
-
-   Use the **TodoWrite tool** to track progress through the artifacts.
-
-   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
-
-   a. **For each artifact that is `ready` (dependencies satisfied)**:
-      - Get instructions:
-        ```bash
-        openspec instructions <artifact-id> --change "<name>" --json
-        ```
-      - The instructions JSON includes:
-        - `context`: Project background (constraints for you - do NOT include in output)
-        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
-        - `template`: The structure to use for your output file
-        - `instruction`: Schema-specific guidance for this artifact type
-        - `resolvedOutputPath`: Resolved path or pattern to write the artifact
-        - `dependencies`: Completed artifacts to read for context
-      - Read any completed dependency files for context
-      - Create the artifact file using `template` as the structure and write it to `resolvedOutputPath`
-      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
-      - Show brief progress: "Created <artifact-id>"
-
-   b. **Continue until all `applyRequires` artifacts are complete**
-      - After creating each artifact, re-run `openspec status --change "<name>" --json`
-      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
-      - Stop when all `applyRequires` artifacts are done
-
-   c. **If an artifact requires user input** (unclear context):
-      - Use **AskUserQuestion tool** to clarify
-      - Then continue with creation
-
-5. **Show final status**
-   ```bash
-   openspec status --change "<name>"
-   ```
-
-**Output**
-
-After completing all artifacts, summarize:
-- Change name and location
-- List of artifacts created with brief descriptions
-- What's ready: "All artifacts created! Ready for implementation."
-- Prompt: "Run `/opsx-apply` or ask me to implement to start working on the tasks."
-
-**Artifact Creation Guidelines**
-
-- Follow the `instruction` field from `openspec instructions` for each artifact type
-- The schema defines what each artifact should contain - follow it
-- Read dependency artifacts for context before creating new ones
-- Use `template` as the structure for your output file - fill in its sections
-- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
-  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact

-name: openspec-sync-specs
-description: Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.
-license: MIT
-compatibility: Requires openspec CLI.

-
-Sync delta specs from a change to main specs.
-
-This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
-
-**Store selection:** If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run `openspec store list --json` to discover registered store ids, then pass `--store <id>` on the commands that read or write specs and changes (`new change`, `status`, `instructions`, `list`, `show`, `validate`, `archive`, `doctor`, `context`). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local `openspec/` root.
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have delta specs (under `specs/` directory).
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Resolve change context**
-
-   Run:
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-
-3. **Find delta specs**
-
-   Use `artifactPaths.specs.existingOutputPaths` from the status JSON as the list of delta spec files.
-
-   Each delta spec file contains sections like:
-   - `## ADDED Requirements` - New requirements to add
-   - `## MODIFIED Requirements` - Changes to existing requirements
-   - `## REMOVED Requirements` - Requirements to remove
-   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
-
-   If no delta specs found, inform user and stop.
-
-4. **For each delta spec, apply changes to main specs**
-
-   For each repo-local capability delta spec path returned by the CLI:
-
-   a. **Read the delta spec** to understand the intended changes
-
-   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
-
-   c. **Apply changes intelligently**:
-
-      **ADDED Requirements:**
-      - If requirement doesn't exist in main spec → add it
-      - If requirement already exists → update it to match (treat as implicit MODIFIED)
-
-      **MODIFIED Requirements:**
-      - Find the requirement in main spec
-      - Apply the changes - this can be:
-        - Adding new scenarios (don't need to copy existing ones)
-        - Modifying existing scenarios
-        - Changing the requirement description
-      - Preserve scenarios/content not mentioned in the delta
-
-      **REMOVED Requirements:**
-      - Remove the entire requirement block from main spec
-
-      **RENAMED Requirements:**
-      - Find the FROM requirement, rename to TO
-
-   d. **Create new main spec** if capability doesn't exist yet:
-      - Create `openspec/specs/<capability>/spec.md`
-      - Add Purpose section (can be brief, mark as TBD)
-      - Add Requirements section with the ADDED requirements
-
-5. **Show summary**
-
-   After applying all changes, summarize:
-   - Which capabilities were updated
-   - What changes were made (requirements added/modified/removed/renamed)
-
-**Delta Spec Format Reference**
-
-```markdown
-## ADDED Requirements
-
-### Requirement: New Feature
-The system SHALL do something new.
-
-#### Scenario: Basic case
-- **WHEN** user does X
-- **THEN** system does Y
-
-## MODIFIED Requirements
-
-### Requirement: Existing Feature
-#### Scenario: New scenario to add
-- **WHEN** user does A
-- **THEN** system does B
-
-## REMOVED Requirements
-
-### Requirement: Deprecated Feature
-
-## RENAMED Requirements
-
-- FROM: `### Requirement: Old Name`
-- TO: `### Requirement: New Name`
-```
-
-**Key Principle: Intelligent Merging**
-
-Unlike programmatic merging, you can apply **partial updates**:
-- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
-- The delta represents *intent*, not a wholesale replacement
-- Use your judgment to merge changes sensibly
-
-**Output On Success**
-
-```
-## Specs Synced: <change-name>
-
-Updated main specs:
-
-**<capability-1>**:
-- Added requirement: "New Feature"
-- Modified requirement: "Existing Feature" (added 1 scenario)
-
-**<capability-2>**:
-- Created new spec file
-- Added requirement: "Another Feature"
-
-Main specs are now updated. The change remains active - archive when implementation is complete.
-```
-
-**Guardrails**
-- Read both delta and main specs before making changes
-- Preserve existing content not mentioned in delta
-- If something is unclear, ask for clarification
-- Show what you're changing as you go
-- The operation should be idempotent - running twice should give same result

+## Context
+
+Animius currently has no shared focus utility layer. Every screen re-implements the same pattern: a `var isFocused by remember { mutableStateOf(false) }` combined with `Modifier.onFocusChanged { isFocused = it.isFocused }` and manual `primary`/`onPrimary` color switching. There are no D-pad interception tools, no focus boundary controls, and no explicit focus order configuration. The project targets `minSdk 26` and already depends on Compose Foundation (which includes `focusProperties`, `focusGroup`, `focusRestorer`, `FocusRequester`, `onKeyEvent`, `onPreviewKeyEvent`). No TV-specific library (`androidx.tv.material3`) is used, and by decision we are not introducing one.
+
+Reference projects studied: `ComposeTv` (uses `handleDPadKeyEvents` modifier + TV M3 components) and `JetStreamCompose` (uses `handleDPadKeyEvents`, `focusOnInitialVisibility`, `FocusRequester.createRefs()` pattern, `bringIntoViewIfChildrenAreFocused`).
+
+## Goals / Non-Goals
+
+**Goals:**
+- Create a minimal set of reusable focus modifiers in `app/.../util/focus/`
+- Fix vertical focus flow on the anime detail page: episodes → episode controls → related
+- Fix vertical focus flow on the appearance settings page: theme mode → (skip color swatches) → switches
+- Replace repetitive per-element `onFocusChanged` boilerplate with a shared `onFocusHighlight` modifier on both screens
+
+**Non-Goals:**
+- Do NOT introduce `androidx.tv.material3` or any new external dependency
+- Do NOT change the visual appearance of focus states (inverse-color pattern stays)
+- Do NOT modify the player screen (separate change)
+- Do NOT refactor other screens (Home, Search, Week, Favourite, Danmaku settings) — they can adopt the utilities later
+- Do NOT implement a full `focusOrder` DSL — start with direction-key interception where needed
+
+## Decisions
+
+### Decision 1: Three utility modifiers, not one unified system
+
+**Chosen:** Three independent modifier files under `app/.../util/focus/`:
+- `FocusHighlight.kt` — replaces `onFocusChanged` + manual color state boilerplate
+- `DpadKeyHandler.kt` — `handleDPadKeyEvents` for direction-key interception
+- `FocusOrder.kt` — thin helpers for `focusProperties` configuration
+
+**Rejected:** A full `FocusManager` Composable wrapper or a `Box`-level focus interceptor. Too heavy for the current needs. These three modifiers address the concrete problems and compose freely.
+
+**Rationale:** Matches the pattern both ComposeTv and JetStreamCompose use — standalone modifier extensions, not a wrapping component. Easy to test, easy to adopt incrementally.
+
+### Decision 2: `handleDPadKeyEvents` uses `onPreviewKeyEvent` for UP/DOWN/LEFT/RIGHT, not `onKeyEvent`
+
+**Chosen:** `onPreviewKeyEvent` (fires before child composables process the event).
+
+**Rejected:** `onKeyEvent` (fires after children).
+
+**Rationale:** When we want to intercept a direction key at a boundary (e.g., skip over ColorBall on ↑↓), we need to consume the event *before* any child inside ColorBall has a chance to receive it. `onPreviewKeyEvent` gives us this priority. Events that should pass through (e.g., ← → within ColorBall) return `false` to let children handle them.
+
+This matches the ComposeTv and JetStreamCompose implementations.
+
+### Decision 3: Detail page — EpisodeListControl becomes a standalone Row
+
+**Current layout:**
+```
+Box {
+    AnimeEpisodes(LazyRow, full-width)
+    EpisodeListControl(floated: Modifier.align(BottomEnd))
+}
+```
+
+**New layout:**
+```
+Column {
+    AnimeEpisodes(LazyRow, full-width)
+    EpisodeListControl(Row, right-aligned, full-width)
+}
+```
+
+The `Box` wrapping is replaced with `Column`. `EpisodeListControl` moves from `Modifier.align(Alignment.BottomEnd)` + `offset(y = ...)` to a simple `Row(horizontalArrangement = Arrangement.End)` inside the `Column`. This creates a proper vertical stacking so Compose's spatial algorithm naturally moves focus: episodes ↔ controls ↔ related.
+
+The visual appearance is preserved because `EpisodeListControl` was already right-aligned; the only change is its Y position (slightly adjusted from the previous offset-based positioning).
+
+### Decision 4: Settings page — ColorBall uses horizontal-only focus with vertical interception
+
+**Approach:** Wrap `ColorBall`'s `LazyRow` in a `Box` with `handleDPadKeyEvents(onUp = { ... }, onDown = { ... })` that manually routes ↑↓ focus past the entire row.
+
+```
+Box(
+    modifier = Modifier.handleDPadKeyEvents(
+        onUp = { themeModeFocusRequester.requestFocus() },
+        onDown = { dynamicColorSwitchFocusRequester.requestFocus() }
+    )
+) {
+    ColorBall LazyRow(...)
+}
+```
+
+Individual color circles inside ColorBall still use standard ← → navigation within the row. The outer Box intercepts ↑↓ before they reach any child.
+
+**Alternative considered:** `focusProperties { up = Cancel; down = Cancel }` on each circle. Rejected because it blocks vertical movement entirely without providing a target — the focus system would do nothing on ↑↓, which is worse UX than the current random-jump behavior.
+
+### Decision 5: Focus highlight stays inline, not extracted from individual screens yet
+
+The `FocusHighlight` modifier will be used on the two target screens (detail, settings). Other screens (Home, Search, Week, Favourite) keep their existing manual `onFocusChanged` patterns. They can be migrated later as a follow-up refactor. This keeps the change focused and minimizes regression risk.
+
+### Decision 6: Package structure
+
+```
+app/src/main/java/com/lanlinju/animius/util/focus/
+├── FocusHighlight.kt      # Modifier.onFocusHighlight()
+├── DpadKeyHandler.kt      # Modifier.handleDPadKeyEvents()
+└── FocusOrder.kt           # FocusPropertiesScope helpers (focusUp/Down/Left/Right)
+```
+
+All three are `Modifier` extension functions at package `com.lanlinju.animius.util.focus`. No new module — stays in `:app`.
+
+## Risks / Trade-offs
+
+| Risk | Mitigation |
+|------|------------|
+| `handleDPadKeyEvents` with `onPreviewKeyEvent` may conflict with existing `onKeyEvent`/`onPreviewKeyEvent` modifiers on the same composable | Read current code for each usage site; only install the modifier where no existing key handler is present |
+| `FocusRequester.requestFocus()` calls from `handleDPadKeyEvents` may fail if the target composable is not yet composed (scrolled off-screen, conditional) | Verify target composables are always in the composition tree when the direction-key callback fires. Detail page elements (episodes, controls, related) are always visible together |
+| Animation-driven `ColorBall` uses `animateDpAsState` — focus border animation may conflict with focus highlight | `onFocusChanged` already exists on `ColorBall` items; replacing with `onFocusHighlight` preserves the same triggers |
+| Changing EpisodeListControl from Box-floating to Column-row shifts the vertical layout slightly | Trivial Y-offset difference; visually negligible since EpisodeListControl was tiny and already near the LazyRow bottom |

+## Why
+
+D-pad focus navigation on the anime detail page and apperance settings page produces unpredictable jump targets. Users pressing down from an episode button land on related anime cards instead of the episode control row (channel/reverse/more), and pressing up from settings toggles lands on a random color swatch mid-row instead of the theme mode selector. The root cause is Compose's default 2D spatial focus algorithm making decisions based on geometric proximity in layouts where elements overlap or span different horizontal widths — the spatially "closest" item is not the logically "next" item.
+
+## What Changes
+
+- **New focus utility toolkit** (`app/.../util/focus/`): A set of lightweight Compose modifiers that layer on top of existing Compose focus APIs (no new library dependency). Includes `onFocusHighlight` (replaces repetitive manual `onFocusChanged` + color switching), and `handleDPadKeyEvents` (direction-key interception for custom navigation boundaries).
+- **Detail page layout refactor**: `EpisodeListControl` moved from a floating `Box(Alignment.BottomEnd)` overlay into an independent row below the episodes `LazyRow`, establishing a clean vertical flow: episodes → controls → related.
+- **Settings page focus boundaries**: `ColorBall` color swatch row configured to only accept horizontal focus traversal (← →), so vertical ↑↓ from the switches below skips over the entire swatch row and lands on the theme mode selector.
+- **Consistent focus highlight style**: All interactive elements on both screens use the shared `onFocusHighlight` modifier instead of per-element `onFocusChanged` boilerplate.
+
+## Capabilities
+
+### New Capabilities
+
+- `tv-focus-traversal`: Predictable vertical and horizontal focus flow for complex layouts where items span different widths or overlap. Covers D-pad navigation boundaries, custom direction interception, and focus group isolation.
+
+### Modified Capabilities
+
+None — this change improves existing focus behavior without altering the visual focus style contract defined in `tv-focus-inverse-color`.
+
+## Impact
+
+- **New files**: `app/.../util/focus/` package (~3 files: `FocusHighlight.kt`, `DpadKeyHandler.kt`, `FocusOrder.kt`)
+- **Modified files**: `AnimeDetailScreen.kt` (layout restructure + adopt shared focus modifiers), `AppearanceScreen.kt` (ColorBall focus isolation + adopt shared modifiers)
+- **No API changes**: Public composable signatures unchanged
+- **No new dependencies**: Uses only `androidx.compose.ui.focus.*` and `androidx.compose.ui.input.key.*` already in the project
+- **No behavior change for touch/mouse users**: Focus modifiers only affect D-pad/keyboard navigation

+## ADDED Requirements
+
+### Requirement: Vertical focus flows through layout rows in order
+Interactive elements in vertically stacked layouts (Column or scrollable equivalent) SHALL transfer focus in visual row order when the user presses up/down on D-pad, regardless of horizontal position differences between elements in adjacent rows.
+
+#### Scenario: Episodes row to controls row (detail page)
+- **WHEN** D-pad focus is on any episode button in the episodes `LazyRow`
+- **THEN** pressing DOWN moves focus to the first focusable item in the `EpisodeListControl` row directly below
+- **AND** pressing UP moves focus to the control above the episodes row
+
+#### Scenario: Controls row to related row (detail page)
+- **WHEN** D-pad focus is on any control button (channel, reverse, or more episodes)
+- **THEN** pressing DOWN moves focus to the first item in the related anime `LazyRow`
+- **AND** pressing UP moves focus to an episode button in the row above
+
+#### Scenario: Theme mode to switch rows (settings page)
+- **WHEN** D-pad focus is on a theme mode `SegmentedButton` (System, Light, or Dark)
+- **THEN** pressing DOWN moves focus to the first focusable item below the color swatch row (the Dynamic Color switch)
+- **AND** pressing UP moves focus to an element above the theme mode row
+
+### Requirement: Color swatch row accepts only horizontal focus traversal
+The `ColorBall` color swatch `LazyRow` in the appearance settings SHALL only accept horizontal (←/→) focus movement. Vertical (↑/↓) key events originating from within the swatch row SHALL be intercepted and redirected to the logical row above or below.
+
+#### Scenario: Vertical key intercepted inside color swatch row
+- **WHEN** D-pad focus is on any color circle inside the `ColorBall` LazyRow
+- **THEN** pressing UP moves focus to the theme mode `SegmentedButtonRow` above
+- **AND** pressing DOWN moves focus to the Dynamic Color `SwitchPref` below
+- **AND** pressing LEFT or RIGHT navigates between color circles within the row (standard behavior)
+
+#### Scenario: Entering the color swatch row from above
+- **WHEN** D-pad focus is on the theme mode selector
+- **AND** user presses RIGHT (or final → moves focus right)
+- **THEN** focus enters the `ColorBall` LazyRow at the first visible color circle
+
+#### Scenario: Exiting the color swatch row to below
+- **WHEN** D-pad focus is on the rightmost color circle in the `ColorBall` LazyRow
+- **AND** user presses RIGHT
+- **THEN** focus moves to the Dynamic Color `SwitchPref` below (or wraps to the next logical control)
+
+### Requirement: Focus highlight uses a shared inverse-color modifier
+All interactive elements SHALL use `Modifier.onFocusHighlight()` instead of requiring per-element `var isFocused by remember` + `Modifier.onFocusChanged` boilerplate. The modifier SHALL apply `primary` background and `onPrimary` content color when the element is focused, matching the existing focus style convention.
+
+#### Scenario: Applying focus highlight to a button
+- **WHEN** a composable uses `Modifier.onFocusHighlight(containerColor = true, contentColor = true)`
+- **AND** the composable receives D-pad focus
+- **THEN** the composable's container displays `MaterialTheme.colorScheme.primary`
+- **AND** its content displays `MaterialTheme.colorScheme.onPrimary`
+
+#### Scenario: Focus highlight with no color change
+- **WHEN** a composable uses `Modifier.onFocusHighlight()` without setting custom colors
+- **AND** the composable receives D-pad focus
+- **THEN** no visual change occurs (the modifier is a no-op — used as a focus-tracking anchor without UI changes)
+
+### Requirement: D-pad direction keys can be intercepted at layout boundaries
+The `Modifier.handleDPadKeyEvents()` extension SHALL allow composables to intercept and handle D-pad direction events (up/down/left/right/enter) before child composables process them, using `onPreviewKeyEvent` priority.
+
+#### Scenario: Intercepting a down press at a vertical boundary
+- **WHEN** a composable uses `Modifier.handleDPadKeyEvents(onDown = { customAction() })`
+- **AND** the composable (or any child) has focus
+- **AND** user presses D-pad DOWN
+- **THEN** `customAction()` is invoked
+- **AND** the key event is consumed (not propagated to children)
+
+#### Scenario: Passing through a non-intercepted direction
+- **WHEN** a composable uses `Modifier.handleDPadKeyEvents(onDown = { ... })` without setting `onLeft`
+- **AND** user presses D-pad LEFT
+- **THEN** the left key event is NOT consumed and propagates to child composables normally

+## Context
+
+The `tv-focus-inverse-color` change introduced focus highlighting across ~40 interactive components in 13 files. It used two repetition patterns:
+
+- **Pattern B** (`onFocusChanged` + `mutableStateOf`): Used for `IconButton`, `DropdownMenuItem`, clickable `Surface`/`Box`. ~40 instances.
+- **Pattern A** (`MutableInteractionSource` + `collectIsFocusedAsState` + `collectIsPressedAsState`): Used for `Button`, `OutlinedButton`, `TextButton`. ~25 instances.
+
+A `rememberIsFocused()` utility already exists in `util/focus/FocusHighlight.kt` (created by `detail-settings-focus-fixes`) and covers Pattern B. `AppearanceScreen` already uses it. All other files still use inline boilerplate.
+
+No utility exists for Pattern A.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Add `rememberInteractionFocus()` to `FocusHighlight.kt` covering Pattern A
+- Migrate all 13 files from inline focus patterns to the two shared functions
+- Delete ~345 lines of duplicated boilerplate
+- Zero behavioral or visual change — same focus colors, same pressed-state handling, same Compose APIs
+
+**Non-Goals:**
+- Do NOT extract `MediaSmall` Card border (different visual pattern)
+- Do NOT extract `NavigationBar` item focus (compound `selected || isFocused` condition)
+- Do NOT extract `Slider` D-pad + thumb animation (too specialized)
+- Do NOT extract `GridLayoutTab` three-state focus
+- Do NOT extract `VideoPlayerControl.AdaptiveIconButton` (already a shared component)
+- Do NOT create a `FocusManager` or wrapper composable — stick to modifier-level utilities
+
+## Decisions
+
+### Decision 1: `rememberInteractionFocus()` returns `Pair<Boolean, MutableInteractionSource>`
+
+**Chosen:** `Pair<Boolean, MutableInteractionSource>` — the boolean is `isActive = isFocused || isPressed`, already resolved.
+
+**Rejected:** Returning `Triple<Boolean, Boolean, MutableInteractionSource>` with separate `isFocused` and `isPressed` values. No call site uses them separately — all combine them into `isActive`.
+
+**Rationale:** Every existing use follows the same pattern: `val isActive = isFocused || isPressed`. Returning the pre-combined boolean saves a line at every call site.
+
+### Decision 2: Two separate functions, not one merged
+
+**Chosen:** `rememberIsFocused()` (Pattern B) and `rememberInteractionFocus()` (Pattern A) as separate functions.
+
+**Rejected:** A single function with a boolean parameter (`withPress = true`). This would create two code paths in one function, making it harder to read at call sites.
+
+**Rationale:** The two patterns serve different component families. Pattern A needs `interactionSource` to pass to `Button`/`OutlinedButton`; Pattern B only needs a `Modifier`. Keeping them separate makes intent explicit at the call site.
+
+### Decision 3: What components are NOT migrated
+
+The following have sufficiently unique focus behavior that extracting them would obscure, not clarify:
+
+| Component | Reason to keep inline |
+|---|---|
+| `MediaSmall` Card | Focus adds a `border()`, not background color — completely different visual pattern |
+| `NavigationBar` items | Has `selected \|\| isFocused` compound condition + `NavigationBarItemDefaults.colors()` — combining with `rememberIsFocused()` would add confusion, not reduce it |
+| `Slider` (video-player) | Focus triggers D-pad key handling + thumb size animation + white border + `pointerInput` — logic is specific to one component |
+| `GridLayoutTab` (HomeScreen) | Three-state: `isFocused` / `selected` / `default` with different colors for each — no other component shares this pattern |
+| `VideoPlayerControl.AdaptiveIconButton` | Already a shared internal component with built-in Pattern A — no migration needed |
+
+### Decision 4: Use destructuring `val (x, y)` syntax
+
+**Chosen:** `val (isFocused, focusModifier) = rememberIsFocused()`
+
+**Rejected:** `val focusState = rememberIsFocused()` then `focusState.first` / `focusState.second`. Less readable.
+
+**Rationale:** Kotlin's destructuring makes the intent clear. The function name already signals what it returns; destructuring names reinforce it.
+
+## Risks / Trade-offs
+
+- **[Risk] Merge conflicts with upstream**: The original author may have their own changes in affected files. → **Mitigation**: This is a pure refactor — every change is a mechanical replacement. If conflicts arise, reverting the refactor is trivial: re-apply the inline pattern at the conflicted site.
+- **[Risk] Spec requirement change**: The original `tv-focus-inverse-color` spec includes "No new abstraction files". → **Mitigation**: This change includes a MODIFIED requirement replacing it with "Shared focus utilities preferred". The delta spec documents the rationale.

+## Why
+
+~450 lines of identical focus boilerplate copied across 13 files — two patterns (`onFocusChanged` + `mutableStateOf` and `MutableInteractionSource` + `collectIsFocusedAsState` + `collectIsPressedAsState`) repeated ~65 times. A `rememberIsFocused()` utility already exists in `util/focus/FocusHighlight.kt` but only `AppearanceScreen` uses it. The Button-family pattern (`rememberInteractionFocus()`) has no shared utility at all. Every new button added to any screen copies the same 4-8 lines of boilerplate, risking typos and inconsistency.
+
+The "No new abstraction files" constraint from the original `tv-focus-inverse-color` spec was well-intentioned (keep diffs self-contained for upstream PR review) but has produced the exact opposite outcome: every file carries a large, repetitive diff that obscures the actual UI changes. A 10-line shared utility reduces each screen's diff to 1-2 lines, making upstream review easier, not harder.
+
+## What Changes
+
+- Add `rememberInteractionFocus()` to `util/focus/FocusHighlight.kt` — replaces the `MutableInteractionSource` + `collectIsFocusedAsState` + `collectIsPressedAsState` + `isActive` chain in Button-family components
+- Migrate all 13 files from inline focus patterns to `rememberIsFocused()` / `rememberInteractionFocus()`
+- Remove ~345 lines of duplicated boilerplate
+- Replace "No new abstraction files" spec requirement with "Shared focus utilities preferred"
+
+## Capabilities
+
+### Modified Capabilities
+
+- `tv-focus-inverse-color`: Replace "No new abstraction files" requirement with "Shared focus utilities preferred" — the visual behavior (primary/onPrimary on focus) is unchanged, but the implementation pattern shifts from per-file inline boilerplate to shared `util/focus/FocusHighlight.kt` utilities.
+
+## Impact
+
+- **Modified files**: 14 files — 1 util file (+10 lines) + 13 screen/component files (~-345 lines net)
+- **Behavior change**: None. Same Compose APIs, same runtime focus → color mapping
+- **No new dependencies**: Uses existing `androidx.compose.foundation.interaction` and `androidx.compose.ui.focus` APIs already in the project
+- **Upstream PR**: Per-screen diffs shrink significantly; shared utility is self-documenting and reviewable once

+## MODIFIED Requirements
+
+### Requirement: No new abstraction files
+Focus inverse-color implementations SHALL use shared utility functions from `util/focus/FocusHighlight.kt` rather than inline per-element boilerplate. New interactive components SHALL adopt `rememberIsFocused()` (for `IconButton`, `DropdownMenuItem`, clickable surfaces) or `rememberInteractionFocus()` (for `Button`, `OutlinedButton`, `TextButton`) instead of re-implementing `onFocusChanged` + `mutableStateOf` or `MutableInteractionSource` + `collectIsFocusedAsState` + `collectIsPressedAsState`.
+
+The two utility functions (`rememberIsFocused()` and `rememberInteractionFocus()`) SHALL be the single source of truth for focus state tracking. When a bug is found in focus state logic, it SHALL be fixed once in the utility file, not in each screen.
+
+#### Scenario: Adding a new IconButton with focus
+- **WHEN** a developer adds a new `IconButton` to any screen that needs D-pad focus highlighting
+- **THEN** they SHALL use `val (isFocused, focusModifier) = rememberIsFocused()` and attach `focusModifier` to the button, reading `isFocused` for `containerColor` and `contentColor`
+- **AND** they SHALL NOT write a new `mutableStateOf(false)` + `onFocusChanged` block
+
+#### Scenario: Adding a new TextButton with focus
+- **WHEN** a developer adds a new `TextButton` to any screen that needs D-pad focus highlighting
+- **THEN** they SHALL use `val (isActive, interactionSource) = rememberInteractionFocus()` and pass `interactionSource` to the button, reading `isActive` for colors
+- **AND** they SHALL NOT write a new `MutableInteractionSource` + `collectIsFocusedAsState` + `collectIsPressedAsState` block
+
+#### Scenario: Code review of a single screen
+- **WHEN** an upstream reviewer inspects the diff of any single screen file
+- **THEN** the focus inverse-color logic SHALL reference `rememberIsFocused()` or `rememberInteractionFocus()` from `util/focus/FocusHighlight.kt`, which is self-documenting and reviewable once

+
+### Decision 7 (v4 — 彻底重构): 放弃 lastPlayedFocusRef，改用 moveFocus
+
+**问题:** 在 LazyRow item 内部用 `LaunchedEffect` 管理 `lastPlayedFocusRef` 产生了一系列
+时序问题：异步窗口期崩溃、倒序后 ref 失效、正序后 `initialFocusDone` 重置导致抢焦点。
+经过 v1-v3 迭代修复均未彻底解决。
+
+**新方案:** 完全放弃 `lastPlayedFocusRef` 机制。
+
+1. `AnimeEpisodes` 不再接收 `lastPlayedFocusRef` 参数
+2. `EpisodeListControl.onUpFocusRequest` 改为 `focusManager.moveFocus(FocusDirection.Up)`
+   — 让 Compose 空间算法自然向上导航到 LazyRow 中空间最近的 episode
+3. `FavouriteIcon.onDown` 同样改为 `focusManager.moveFocus(FocusDirection.Down)`
+4. 初始 focus：`AnimeEpisodes` 函数级别用 `LaunchedEffect(Unit)` 滚动到 `lastPosition`
+   并 `requestFocus` 第一个可见 item（通过 `scrollState.firstVisibleItemIndex` 获取）
+5. 倒序后焦点留在按钮上（不抢），按↑时 `moveFocus(Up)` 自然导航
+
+**优势:**
+- 无 FocusRequester 生命周期问题（不存储跨 composable 引用）
+- 无异步时序窗口
+- 倒序/正序切换不抢焦点
+- `moveFocus` 是 Compose 原生 API，稳定可靠
+
+**代价:**
+- 按↑从控件行到集数时，聚焦到空间最近的 episode（不一定是最后播放的）
+- 但 LazyRow 已滚动到 `lastPosition` 附近，所以空间最近的通常就是最后播放的
+
+### Decision 8: Reverse list button shows toggle state
+
+**Chosen:** Change button text based on current `reverseList` state.
+When `reverseList` is `false`, show the string resource `reverse_list` ("列表倒序").
+When `reverseList` is `true`, show "列表正序". No new string resource needed —
+hardcoded Chinese literal since other UI text in this row ("线路", "更多") is also hardcoded.

+# TV Focus Traversal
+
+## Purpose
+
+Ensure predictable vertical and horizontal D-pad focus flow for complex Compose layouts where items span different widths or overlap, using direction-key interception and focus group isolation to override Compose's default 2D spatial algorithm when it produces wrong targets.
+
+## Requirements
+
+### Requirement: Vertical focus flows through layout rows in order
+Interactive elements in vertically stacked layouts (Column or scrollable equivalent) SHALL transfer focus in visual row order when the user presses up/down on D-pad, regardless of horizontal position differences between elements in adjacent rows.
+
+#### Scenario: Episodes row to controls row (detail page)
+- **WHEN** D-pad focus is on any episode button in the episodes `LazyRow`
+- **THEN** pressing DOWN moves focus to the first focusable item in the `EpisodeListControl` row directly below
+- **AND** pressing UP moves focus to the control above the episodes row
+
+#### Scenario: Controls row to related row (detail page)
+- **WHEN** D-pad focus is on any control button (channel, reverse, or more episodes)
+- **THEN** pressing DOWN moves focus to the first item in the related anime `LazyRow`
+- **AND** pressing UP moves focus to the last played episode button in the row above
+
+#### Scenario: Favourite button to last played episode (detail page)
+- **WHEN** D-pad focus is on the FavouriteIcon (heart button)
+- **THEN** pressing DOWN moves focus to the last played episode button
+
+#### Scenario: Reverse list preserves last played focus (detail page)
+- **WHEN** user toggles reverse list
+- **AND** presses UP from EpisodeListControl
+- **THEN** focus moves to the last played episode button (not a different episode)
+
+#### Scenario: Theme mode to switch rows (settings page)
+- **WHEN** D-pad focus is on a theme mode `SegmentedButton` (System, Light, or Dark)
+- **THEN** pressing DOWN moves focus to the first focusable item below the color swatch row (the Dynamic Color switch)
+- **AND** pressing UP moves focus to an element above the theme mode row
+
+### Requirement: Color swatch row accepts only horizontal focus traversal
+The `ColorBall` color swatch `LazyRow` in the appearance settings SHALL only accept horizontal (←/→) focus movement. Vertical (↑/↓) key events originating from within the swatch row SHALL be intercepted and redirected to the logical row above or below.
+
+#### Scenario: Vertical key intercepted inside color swatch row
+- **WHEN** D-pad focus is on any color circle inside the `ColorBall` LazyRow
+- **THEN** pressing UP moves focus to the theme mode `SegmentedButtonRow` above
+- **AND** pressing DOWN moves focus to the Dynamic Color `SwitchPref` below
+- **AND** pressing LEFT or RIGHT navigates between color circles within the row (standard behavior)
+
+#### Scenario: Entering the color swatch row from above
+- **WHEN** D-pad focus is on the theme mode selector
+- **AND** user presses RIGHT (or final → moves focus right)
+- **THEN** focus enters the `ColorBall` LazyRow at the first visible color circle
+
+#### Scenario: Exiting the color swatch row to below
+- **WHEN** D-pad focus is on the rightmost color circle in the `ColorBall` LazyRow
+- **AND** user presses RIGHT
+- **THEN** focus moves to the Dynamic Color `SwitchPref` below (or wraps to the next logical control)
+
+### Requirement: Focus highlight uses a shared inverse-color modifier
+All interactive elements SHALL use `rememberIsFocused()` instead of requiring per-element `var isFocused by remember` + `Modifier.onFocusChanged` boilerplate.
+
+#### Scenario: Applying focus highlight to a button
+- **WHEN** a composable uses `rememberIsFocused()` to obtain `(isFocused, focusModifier)`
+- **AND** the composable receives D-pad focus
+- **THEN** the `isFocused` state becomes `true`, allowing the composable to apply `primary` background and `onPrimary` content color
+
+### Requirement: D-pad direction keys can be intercepted at layout boundaries
+The `Modifier.handleDPadKeyEvents()` extension SHALL allow composables to intercept and handle D-pad direction events (up/down/left/right/enter) before child composables process them, using `onPreviewKeyEvent` priority.
+
+#### Scenario: Intercepting a down press at a vertical boundary
+- **WHEN** a composable uses `Modifier.handleDPadKeyEvents(onDown = { customAction() })`
+- **AND** the composable (or any child) has focus
+- **AND** user presses D-pad DOWN
+- **THEN** `customAction()` is invoked
+- **AND** the key event is consumed (not propagated to children)
+
+#### Scenario: Passing through a non-intercepted direction
+- **WHEN** a composable uses `Modifier.handleDPadKeyEvents(onDown = { ... })` without setting `onLeft`
+- **AND** user presses D-pad LEFT
+- **THEN** the left key event is NOT consumed and propagates to child composables normally

Subject: [PATCH 18/41] feat(video-player): TV D-pad focus navigation, slider
 thumb animation, compact seek overlay
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Slider: fix onFocusChanged modifier order (before focusable) so thumb animates on focus (15→20dp + 3dp white border)
- Slider: onKeyEvent uses onClick instead of onValueChange+onValueChangeFinished to avoid isSeeking toggle
- Slider: D-pad seek step unified to 10s; remove unused focusedColor param
- focusProperties explicit routing: back↔slider↔playPause via FocusRequester (bypasses outer fillMaxSize Box)
- Hidden-UI LEFT/RIGHT: 10s seek + compact overlay (isSeeking hides header/playback) + focus slider for continuous seek
- hideAfterMs: 1.5s short timer during seek, 6s default; onSeeked no longer resets isSeeking (no full UI flash)
- onTimedSeek added to VideoPlayerState interface+impl; UP/DOWN/OK show full UI with deferred focus
- hideControlUi no longer resets isSeeking; showControlUi resets isSeeking=false + hideAfterMs=6s
- Fullscreen button hidden on TV (FEATURE_LEANBACK)
- Speed/resize side sheets: auto-focus first item + BackHandler + selected item bold
- Auto-hide timer resets on D-pad via onPreviewKeyEvent + onUserInteraction
- TimelineIndicator hidden with control UI (add isControlUiVisible check)
- Remove unused controlFocusRequester, wildcard imports

+## Context
+
+The video player has a control overlay (`VideoPlayerControl`) with three visual rows:
+1. **Header row**: Back button, title, options (Forward 85s + MoreVert dropdown)
+2. **Slider row**: Timeline label + fullscreen toggle, then the progress slider
+3. **Playback control row**: Play/pause, next episode, danmaku toggle (left group); speed, resize, episode selection (right group)
+
+Currently there is no structured D-pad focus flow between these rows. The `defaultRemoteControlHandler` on the outer `VideoPlayer` handles basic show/hide and play/pause, but when controls are visible, focus navigation between rows is left to Compose's default spatial algorithm, which can produce wrong targets because row items have varying widths and horizontal positions.
+
+The custom `Slider` already has its own D-pad left/right handling for seeking, but always uses a single `color` parameter (currently set to `inversePrimary`) for the progress track and thumb, providing no visual distinction between focused and unfocused states.
+
+### Constraints
+- The `video-player` module is a separate Gradle module from `app` and cannot depend on `app`'s shared focus utilities (`DpadKeyHandler.kt`, `FocusHighlight.kt`)
+- The `Slider` component is in the `video-player` module
+- The slider must remain usable via touch (drag/tap) regardless of focus state
+- No external TV library dependency (consistent with existing focus architecture)
+
+## Goals / Non-Goals
+
+**Goals:**
+- Predictable vertical D-pad focus flow: header ↔ slider ↔ playback controls
+- Horizontal navigation within each row (left/right for buttons, seeking for slider)
+- Visual focus feedback on the slider via color change (primary when focused, dimmer when not)
+- Works with existing `defaultRemoteControlHandler` (no regression in remote control behavior)
+
+**Non-Goals:**
+- Rewriting the entire player controller UI structure
+- Changing the slider's existing D-pad seek step size
+- Touch/gesture behavior changes
+
+## Decisions
+
+### Decision 1: Back key hides UI first, exits on second press
+
+**Choice**: When the player control UI is visible, pressing Back hides the UI (calls `playerState.hideControlUi()`). When the UI is already hidden, Back exits the player normally via `onBackPress`.
+
+**Rationale**: This matches standard media player behavior on Android TV (YouTube, Netflix). Users open controls to check progress or adjust settings — a single Back should dismiss the overlay, not exit the player.
+
+**Implementation**: The `BackHandler` in `VideoPlayer` currently calls `onBackPress()` unconditionally. Change it to check `playerState.isControlUiVisible` — if visible, hide controls; otherwise, call `onBackPress`.
+
+### Decision 2: Direction key shortcuts — compact overlay with slider focus for LEFT/RIGHT continuous seek
+
+**Choice**: When controls are hidden and user presses LEFT/RIGHT, a **compact overlay** appears (only slider + timestamp visible; header and playback rows hidden by `isSeeking = true`) AND **focus is placed on the slider**. Because the slider now has focus, subsequent LEFT/RIGHT presses are handled by the slider's own `onKeyEvent` — enabling **continuous seek** via repeated presses or hold. The compact overlay auto-hides via the normal 6-second auto-hide timer (not a custom 1.5s coroutine).
+
+Hidden UI shortcuts:
+- **LEFT** → 10-second seek back, show compact overlay, focus slider
+- **RIGHT** → 10-second seek forward, show compact overlay, focus slider
+- **UP** → show full control UI, focus Forward 85s button
+- **DOWN** → show full control UI, focus "选集" button
+- **OK/Center** → pause + show full control UI, focus play/pause
+
+Full UI + slider focus (10s seek):
+- **LEFT** → slider's own `onKeyEvent` seeks 10s back (continuous)
+- **RIGHT** → slider's own `onKeyEvent` seeks 10s forward (continuous)
+
+**Rationale**: The previous design used a 1.5s auto-hide coroutine and did not focus the slider, so subsequent LEFT/RIGHT presses had no handler (the outer Box's `onKeyEvent` returns false when `isControlUiVisible` is true, and the slider had no focus). By focusing the slider on the first press, continuous seek works naturally — the slider's own `onKeyEvent` handles every subsequent press. Reusing the normal 6s auto-hide timer (reset by `onUserInteraction()` on every key via `onPreviewKeyEvent`) means the overlay stays visible while the user keeps pressing, and disappears 6s after the last press. `isSeeking = true` keeps the overlay compact (hides header + playback rows); it is reset to `false` in `hideControlUi()` so the next `showControlUi()` renders the full UI.
+
+**Implementation**: `onTimedSeek(skipMs)` is a new method on `VideoPlayerState` (implemented in `VideoPlayerStateImpl`):
+1. If UI not visible, `showControlUi()` — starts the auto-hide timer (resets `isSeeking=false` + `hideAfterMs=6s`)
+2. `isSeeking.value = true` — overrides `showControlUi`'s reset, hides header + playback rows (compact overlay)
+3. `hideAfterMs = seekHideAfterMs` (1500ms) — overrides `showControlUi`'s 6s with a shorter 1.5s timer
+4. `controlUiLastInteractionMs = 0` — reset timer so 1.5s counts from this seek
+5. Compute new position, update `videoProgress`, call `player.seekTo(newPos)`
+
+In `VideoPlayerScreen.kt`, the outer Box's `onKeyEvent` calls `playerState.onTimedSeek(±10000)` then sets `pendingFocusTarget = FocusTarget.SLIDER` for the deferred focus queue.
+
+**Critical: `isSeeking` lifecycle** — `isSeeking` is NOT reset in `hideControlUi()` or `onSeeked()`. It stays true during fade-out so the compact overlay fades out directly (no full UI flash). It is reset to `false` only in `showControlUi()`, so the next time the UI is shown (tap or UP/DOWN/OK), it starts in full UI mode.
+
+**Short seek timer**: A new `hideAfterMs` variable (default 6s, set to 1.5s during seeking) controls the auto-hide delay. The polling loop in `showControlUi()` checks `controlUiLastInteractionMs >= hideAfterMs`. `onUserInteraction()` (called on every D-pad key via `onPreviewKeyEvent`) resets `controlUiLastInteractionMs = 0`, so continuous D-pad pressing keeps resetting the 1.5s timer. The overlay hides 1.5s after the last key press.
+
+**Touch drag**: `onSeeking()` reorders to call `showControlUi()` before setting `isSeeking=true` (so `showControlUi`'s `isSeeking=false` reset doesn't clobber it). `onSeeked()` no longer resets `isSeeking` — it sets `hideAfterMs = 1.5s` and resets the timer, so the compact overlay hides 1.5s after drag release without flashing to full UI.
+
+### Decision 3: Default focus on initial load
+
+**Choice**: After `LaunchedEffect(url)` calls `showControlUi()`, use `LaunchedEffect(Unit)` with `runCatching` to request focus on the play/pause button.
+
+**Rationale**: `showControlUi()` is called on initial playback start but no FocusRequester is ever invoked programmatically. The user sees controls but D-pad is dead until they press a direction key. Defaulting to play/pause gives an immediate, natural starting point.
+
+### Decision 4: Fullscreen button hidden on TV
+
+**Choice**: The `TimelineControl` composable SHALL use `LocalContext.current.packageManager.hasSystemFeature(PackageManager.FEATURE_LEANBACK)` to detect TV devices. On TV, the fullscreen toggle button is not rendered at all.
+
+**Rationale**: The fullscreen toggle is a phone-only feature — it switches between landscape fullscreen and portrait 16:9. On TV, both orientation changes are skipped (`isAndroidTV` / `isWideScreen` guards return early), and the screen is already ~16:9. Hiding it entirely removes an unnecessary dead control from the UI and eliminates it from the focus flow automatically.
+
+### Decision 5: Explicit focusProperties routing + focusable anchor
+
+**Choice**: Two mechanisms work together:
+
+1. **Outer Box** gets `.focusable()` + `onKeyEvent` handler (`handlePlayerKeys`). When the control UI is hidden, this Box holds focus — providing a Compose focus node so key events are dispatched. `handlePlayerKeys` intercepts LEFT/RIGHT (KeyDown, 10s seek + compact overlay + `pendingFocusTarget = SLIDER` to focus the slider) and UP/DOWN/OK (KeyUp, show controls + focus target). After the first LEFT/RIGHT, the slider has focus and handles subsequent presses itself.
+
+2. **Row-level `focusProperties`** on the back button, slider, and play/pause button explicitly declare direction targets using `FocusRequester` references. This bypasses Compose's spatial search entirely — which cannot work because the outer `focusable` Box at `fillMaxSize` always appears "closest" to every candidate.
+
+| Component | `focusProperties` |
+|---|---|
+| Back button (IconButton) | `down = sliderFocusRequester` |
+| Slider (Box) | `up = backFocusRequester`; `down = playPauseFocusRequester` |
+| PlayPause button (AdaptiveIconButton) | `up = sliderFocusRequester` |
+
+**Rationale**: After attempting spatial search, `moveFocus()`, `requestFocus()` safety nets, and `canFocus = false`, the root issue is that the outer Box MUST be focusable (for hidden-UI key dispatch) but MUST NOT participate in spatial search (it's `fillMaxSize` and always wins). `focusProperties` with explicit FocusRequester targets is the only mechanism that satisfies both constraints. The Compose focus skill advises: "Use this sparingly. Too many hard-coded links create stale focus graphs when layouts change. Prefer natural focus order unless the design requires a specific jump or trap." This is that case — the outer Box is an unavoidable trap that requires explicit routing.
+
+**Implementation**:
+- `VideoPlayerScreen.kt`: Outer Box gets `.focusable() + onKeyEvent(handlePlayerKeys)`
+- `VideoPlayerControl.kt`: Back `IconButton` gets `Modifier.focusProperties { down = sliderFocusRequester }`; `Slider` Box gets `Modifier.focusProperties { up = backFocusRequester; down = playPauseFocusRequester }`; `PlayPauseButton` gets `Modifier.focusProperties { up = sliderFocusRequester }`
+- New FocusRequester: `backFocusRequester`
+- `Slider.kt`: expose `focusProperties` via a `focusPropertiesModifier` parameter or apply it in `BottomControlBar`
+
+### Decision 6: Slider focus feedback — thumb-only, no track color change
+
+**Choice**: The slider signals D-pad focus through thumb animations only: thumb grows from 15dp to 20dp and gains a **3dp white border**. The track color (play progress, buffered, unplayed) remains unchanged on focus. The `focusedColor` parameter exists for callers who explicitly want focused track differentiation but defaults to `primary` (same as `color`).
+
+| Parameter | Default | Meaning |
+|---|---|---|
+| `color` | `MaterialTheme.colorScheme.primary` | Play progress + thumb (unfocused) |
+| `focusedColor` | `MaterialTheme.colorScheme.primary` | Play progress + thumb (focused) — same as unfocused by default |
+| `trackColor` | `Color.LightGray.copy(alpha = 0.38f)` | Unplayed track (unchanged) |
+| `secondTrackColor` | `Color.LightGray.copy(alpha = 0.78f)` | Buffered track (unchanged) |
+
+**Rationale**: The default `color` is the app's brand `primary` — changing it to white would alter the phone UX for the sake of TV focus, which is the wrong trade-off. The thumb's size increase (15→20dp) and white border (0→3dp) already provide clear, unambiguous focus feedback without touching track colors at all. This keeps phone and TV experiences unified: the slider looks the same on both form factors, with TV adding only the thumb animation overlay.
+
+**Critical fix — `onFocusChanged` order**: The thumb animation was not working because `.onFocusChanged { ... }` was placed **after** `.focusable()` in the modifier chain. In Compose, `onFocusChanged` must be placed **before** `.focusable()` to observe the focusable node's own focus state. When placed after, it observes a child node and `isFocused` never becomes true. See Decision 11 for details.
+
+**Slider D-pad seek step**: Changed to 10 seconds (`10000f / durationMs`). 10s is the standard TV seek step (YouTube TV, Netflix). This unifies the hidden-UI quick seek and the focused-slider seek to the same step size, so the first press and subsequent presses feel consistent.
+
+### Decision 7: No shared utility dependency for video-player module
+
+**Choice**: Use inline `onKeyEvent` for row boundaries and inline focus state tracking in `VideoPlayerControl.kt`, consistent with the module's existing self-contained approach (`AdaptiveIconButton`, `AdaptiveTextButton`).
+
+**Rationale**: The `video-player` module already has its own focus patterns using `MutableInteractionSource` and `onFocusChanged`. Adding a dependency on `app` module or creating a shared utility module would be architectural overhead for a single consumer. The module's self-contained focus helpers (`AdaptiveIconButton`, `AdaptiveTextButton`) already work well — we just extend the pattern to row navigation.
+
+### Decision 8: Focus routing target selection
+
+**Choice**: When pressing DOWN from the header row, move focus to the slider. When pressing DOWN from the slider, move focus to the first button in the playback control row (play/pause). UP reverses the flow.
+
+**Rationale**: This follows the visual layout: header is topmost, slider is middle, playback controls are bottom. The slider is the most important control for seeking, so DOWN from header goes there first. UP from slider goes to back button in header (the most prominent header control).
+
+### Decision 9: Speed/resize side sheets receive auto-focus and Back support
+
+**Choice**: Add `FocusRequester` + `LaunchedEffect(Unit)` to the first item in `SpeedSideSheet` and `ResizeSideSheet`. Add `BackHandler` to both side sheets to close on Back key press.
+
+**Rationale**: Currently `showSpeedUi()` calls `hideControlUi()`, which removes the entire `VideoPlayerControl` composable tree from composition — including whichever button had focus (e.g., the "倍速" button). When the side sheet appears via `AnimatedVisibility`, no element requests focus, so the D-pad has no target. This is why side sheet items appear "unfocusable."
+
+The `AdaptiveTextButton` composable already has full inverse-color focus handling (`collectIsFocusedAsState` + `collectIsPressedAsState`), so once focus enters the side sheet, highlighting works automatically. No color changes needed in `AdaptiveTextButton`.
+
+**Implementation**:
+- First `AdaptiveTextButton` in each side sheet gets `Modifier.focusRequester(focusRequester)`
+- `LaunchedEffect(Unit) { runCatching { focusRequester.requestFocus() } }` places focus on the first item
+- `BackHandler { onDismissRequest() }` closes the sheet on Back key
+- On dismiss, `VideoPlayerControl` reappears; existing slider focus behavior resumes
+
+### Decision 10: Auto-hide timer resets on any D-pad key event
+
+**Choice**: Add a `Modifier.onPreviewKeyEvent` on the inner `VideoPlayer` Box that calls `playerState.onUserInteraction()` — which resets `controlUiLastInteractionMs` to 0 — and returns `false` (does not consume the event). Add `onUserInteraction()` to the `VideoPlayerState` interface.
+
+**Rationale**: The current auto-hide timer (`controlUiLastInteractionMs`) only resets on button clicks (`play()`, `pause()`, `onSeeking()`, `onClickSlider()`, etc.) and `showControlUi()`. D-pad navigation keys (UP/DOWN/LEFT/RIGHT/OK) do NOT reset the timer. This means:
+- When browsing DropdownMenu items with D-pad, the timer keeps counting.
+- When navigating between control buttons, the timer keeps counting.
+- The UI can disappear mid-navigation.
+
+Using `onPreviewKeyEvent` at the `VideoPlayer` Box level (priority before any child) and returning `false` ensures:
+- Every D-pad key resets the timer.
+- No keys are consumed — child composables (slider seeking, dropdown menu, etc.) continue to work normally.
+
+**Implementation**:
+- `VideoPlayerState` interface gets `fun onUserInteraction()` (default no-op for backwards compatibility)
+- `VideoPlayerStateImpl` implements it as `controlUiLastInteractionMs = 0`
+- Inner `VideoPlayer` Box gets `.onPreviewKeyEvent { playerState.onUserInteraction(); false }`
+
+### Decision 11: Fix `onFocusChanged` modifier order in Slider.kt
+
+**Choice**: Move `.onFocusChanged { isFocused = it.isFocused }` to **before** `.focusable()` in the Slider's modifier chain.
+
+**Rationale**: This was the root cause of Bug 1 (thumb never animating in full UI). In Compose, modifier order matters for focus: `onFocusChanged` observes the focus state of the node created by the **next** modifier in the chain. When `onFocusChanged` is placed after `focusable()`, it observes a child of the focusable node, and `it.isFocused` never becomes true. The correct order is:
+
+```kotlin
+modifier
+    .focusRequester(focusRequester)
+    .onFocusChanged { isFocused = it.isFocused }  // BEFORE focusable
+    .focusable()
+    .onKeyEvent { ... }
+```
+
+This is documented in the Compose focus API: "onFocusChanged should be placed before focusable/focusGroup modifiers to observe their focus state."
+
+### Decision 12: Unify hidden-UI seek with slider focus (continuous seek)
+
+**Choice**: When the user presses LEFT/RIGHT with the UI hidden, the compact overlay appears AND the slider receives focus (`pendingFocusTarget = FocusTarget.SLIDER`). Subsequent LEFT/RIGHT presses are then handled by the slider's own `onKeyEvent` — enabling continuous seek via repeated presses or hold.
+
+**Rationale**: The previous design did not focus the slider on the first LEFT/RIGHT press. After `showControlUi()` set `isControlUiVisible = true`, the outer Box's `onKeyEvent` returned false (because `if (isControlUiVisible) return false`), and the slider had no focus — so subsequent LEFT/RIGHT presses went nowhere. The user observed "无UI时按左右键有放大加白边但是依然无法长按或多次按键来持续快退快进" — the thumb appeared to animate (because `isSeeking = true` drove `isActive`), but continuous seek did not work. By focusing the slider on the first press, the slider's own `onKeyEvent` takes over and continuous seek works naturally.
+
+**Implementation**:
+- Add `FocusTarget.SLIDER` to the enum
+- In the outer Box's `onKeyEvent`, LEFT/RIGHT KeyDown: after `onTimedSeek(...)`, set `pendingFocusTarget = FocusTarget.SLIDER`
+- The existing `LaunchedEffect(pendingFocusTarget)` deferred focus queue handles the `sliderFocusRequester.requestFocus()` call after `AnimatedVisibility` composes
+
+### Decision 13: Slider D-pad seek uses `onClick` instead of `onValueChange` + `onValueChangeFinished`
+
+**Choice**: The slider's `onKeyEvent` for LEFT/RIGHT calls `onClick(progress)` (which maps to `state.onClickSlider` — updates `videoProgress` + seeks the player directly) instead of `onValueChange(progress)` + `onValueChangeFinished()` (which map to `state.onSeeking` + `state.onSeeked` — sets `isSeeking = true` then `false`).
+
+**Rationale**: `onSeeking` sets `isSeeking = true` and `onSeeked` sets `isSeeking = false`. If the slider's `onKeyEvent` used this path, each D-pad seek press would flip `isSeeking` true→false, causing the compact overlay (which relies on `isSeeking = true` to hide header + playback rows) to flash back to full UI on each press. By using `onClick` (which does NOT toggle `isSeeking`), the compact overlay stays compact during continuous seek. The thumb animation is driven by `isFocused` (Decision 11 fix), not `isSeeking`, so it remains visible throughout.
+
+**Implementation** in `Slider.kt`:
+```kotlin
+.onKeyEvent { event ->
+    if (event.type == KeyEventType.KeyDown) {
+        val stepFraction = if (durationMs > 0) 10000f / durationMs else 0.02f
+        when (event.key) {
+            Key.DirectionRight -> { onClick((value + stepFraction).coerceIn(0f, 1f)); true }
+            Key.DirectionLeft -> { onClick((value - stepFraction).coerceIn(0f, 1f)); true }
+            else -> false
+        }
+    } else false
+}
+```
+
+### Decision 14: Unify seek step to 10 seconds
+
+**Choice**: Both the hidden-UI quick seek (`onTimedSeek`) and the focused-slider D-pad seek use **10 seconds** (`10000ms` / `10000f / durationMs`).
+
+**Rationale**: The previous design used 5s for hidden-UI and 30s for focused-slider. Now that hidden-UI seek focuses the slider (Decision 12), the first press (10s via `onTimedSeek`) and subsequent presses (via slider's `onKeyEvent`) must use the same step — otherwise the first press jumps 5s and subsequent presses jump 30s, which feels jarring. 10s is the standard TV seek step (YouTube TV, Netflix, Android TV system media controls). The `ExoPlayer.Builder` config in `rememberVideoPlayerState` also sets `setSeekForwardIncrementMs(15 * 1000)` / `setSeekBackIncrementMs(15 * 1000)` — these should be updated to 10s as well for consistency, though they are only used by `control.forward()` / `control.rewind()` which are not currently called by D-pad handlers.
+
+**Implementation**:
+- `Slider.kt`: `stepFraction = 10000f / durationMs`
+- `VideoPlayerScreen.kt` `onTimedSeek`: `skipMs = ±10000`
+- `VideoPlayerSate.kt` `rememberVideoPlayerState`: `setSeekForwardIncrementMs(10 * 1000)`, `setSeekBackIncrementMs(10 * 1000)`
+
+## Risks / Trade-offs
+
+- **Risk**: `onKeyEvent` at row level may interfere with the slider's own left/right key handling.
+  - **Mitigation**: Use `onKeyEvent` (not `onPreviewKeyEvent`) so child composables consume keys first. Only intercept Up/Down which the slider doesn't handle anyway.
+
+- **Risk**: The player control's `AnimatedVisibility` enter/exit may cause `FocusRequester` timing issues (similar to the reverse list crash on detail page).
+  - **Mitigation**: Use `runCatching` for `requestFocus()` calls and avoid storing `FocusRequester` across composable lifecycles.
+
+- **Trade-off**: The `focusedColor` addition makes the Slider API slightly larger, but it's a single optional parameter with a sensible default.

+## Why
+
+The video player control overlay currently has no structured D-pad focus navigation between its rows (header, slider, playback controls). When the user presses up/down, focus jumps unpredictably. Additionally, the progress slider always uses the `primary` color regardless of focus state, making it hard to tell when the slider is focused — a problem for TV users who rely on clear focus indicators.
+
+## What Changes
+
+- **Player control focus routing**: Add D-pad vertical navigation boundaries between the three control rows (header, slider, playback), so up/down moves predictably between rows while left/right navigates within each row.
+- **Slider focus-aware color**: The `Slider` component will indicate D-pad focus via the thumb only — the thumb grows larger (15→20dp) and gains a 3dp white border when focused. The progress track and buffered track colors remain unchanged (defaulting to `primary`), consistent with both phone and TV usage. The `focusedColor` parameter is available for callers that want focused track color differentiation, but defaults to `primary` (no track change). A critical fix moves `.onFocusChanged` before `.focusable()` in the modifier chain so the focus callback actually fires.
+- **Direction key shortcuts when UI hidden**: When the control overlay is hidden: pressing LEFT/RIGHT seeks 10 seconds, shows a compact overlay (slider + timestamp only), AND focuses the slider so subsequent LEFT/RIGHT presses continuously seek via the slider's own key handler; pressing UP shows UI and focuses the Forward 85s button; pressing DOWN shows UI and focuses the "选集" button; pressing OK/Center pauses playback, shows UI, and focuses the play/pause button.
+- **Unified 10-second seek step**: Both the hidden-UI quick seek and the focused-slider D-pad seek use 10 seconds, so the first press and subsequent continuous presses feel consistent.
+- **Default focus on load**: When the player first opens with the control UI visible, focus defaults to the play/pause button so D-pad navigation is immediately available.
+- **Back key hides UI**: When the control overlay is visible, pressing Back hides the UI instead of exiting the player. Pressing Back again (with UI hidden) exits the player.
+- **Speed/resize side sheet focus**: When the speed or resize side sheet opens, focus is automatically placed on the first selectable item. Pressing Back closes the side sheet and returns focus to the main control UI. The currently selected item uses bold text in addition to `primary` color for clear visual distinction.
+- **Auto-hide timer respects D-pad**: The player UI auto-hide timer resets on ANY D-pad key event (including navigation keys), not just button clicks. This prevents the UI from disappearing while the user is browsing with the remote.
+
+## Capabilities
+
+### New Capabilities
+- `player-focus-navigation`: Structured D-pad focus flow between the three control rows in the video player overlay — header (back + options) → slider → playback controls (play/pause, next, danmaku, speed, resize, episode). Up/down moves between rows; left/right navigates within each row.
+
+### Modified Capabilities
+- `tv-focus-inverse-color`: The Slider component SHALL use `primary` color only when focused. When unfocused, it uses a dimmer color (the `color` parameter), consistent with the inverse-color pattern used by buttons.
+
+## Impact
+
+- `video-player/src/.../component/Slider.kt`: Fix `onFocusChanged` modifier order (before `.focusable()`); change D-pad seek step to 10s; use `onClick` instead of `onValueChange`+`onValueChangeFinished` in `onKeyEvent`; `focusedColor` parameter retained (defaults to `primary`, no track color change on focus)
+- `video-player/src/.../VideoPlayerControl.kt`: Add `onKeyEvent` boundaries; expose FocusRequesters; hide fullscreen button on TV; Slider call site simplified (no need for `progressLineColor`)
+- `video-player/src/.../VideoPlayer.kt`: Back key hides UI first; `onPreviewKeyEvent` resets auto-hide timer
+- `video-player/src/.../VideoPlayerSate.kt`: `hideControlUi()` resets `isSeeking = false`; `rememberVideoPlayerState` seek increments changed to 10s
+- `app/.../videoplayer/VideoPlayerScreen.kt`: `defaultRemoteControlHandler` — LEFT/RIGHT hidden=10s seek + compact overlay + focus slider (continuous seek), UP/DOWN/OK show UI+focus targets; `LaunchedEffect` for default play/pause focus on load; Speed/Resize side sheet FocusRequester + BackHandler

+- **AND** the `onFocusChanged` modifier is placed before `.focusable()` so the focus callback fires
+
+### Requirement: Initial focus on control show
+When the player control overlay becomes visible via D-pad input or initial load, focus SHALL be placed on the appropriate control.
+
+#### Scenario: Default focus on initial player load
+- **WHEN** the player first opens
+- **AND** the control UI is visible
+- **THEN** focus is on the play/pause button
+

+- **THEN** playback seeks backward 10 seconds
+- **AND** a compact overlay appears showing the progress slider and timestamp
+- **AND** the full control overlay (header, playback buttons) does NOT appear
+- **AND** focus is placed on the slider so subsequent LEFT presses continuously seek
+
+#### Scenario: Right key with hidden UI
+- **WHEN** user presses RIGHT on D-pad while controls are hidden
+- **THEN** playback seeks forward 10 seconds
+- **AND** a compact overlay appears showing the progress slider and timestamp
+- **AND** the full control overlay (header, playback buttons) does NOT appear
+- **AND** focus is placed on the slider so subsequent RIGHT presses continuously seek
+
+#### Scenario: Continuous seek from hidden UI
+- **WHEN** user presses LEFT or RIGHT while controls are hidden

+
+#### Scenario: Controls shown via up key
+- **WHEN** user presses UP on D-pad while controls are hidden
+- **THEN** the control overlay becomes visible
+- **AND** focus is placed on the Forward 85s button in the header row
+
+#### Scenario: Controls shown via down key
+- **WHEN** user presses DOWN on D-pad while controls are hidden
+- **THEN** the control overlay becomes visible
+- **AND** focus is placed on the "选集" (episode) text button in the playback control row
+
+#### Scenario: Controls shown via OK/Center key
+- **WHEN** user presses OK/Center on D-pad while controls are hidden
+- **AND** the video is currently playing
+- **THEN** playback pauses
+- **AND** the control overlay becomes visible
+- **AND** focus is placed on the play/pause button
+
+### Requirement: Back key hides player control UI
+When the player control overlay is visible, pressing the Back key SHALL hide the overlay instead of exiting the player.
+
+#### Scenario: Back key with UI visible
+- **WHEN** the player control overlay is visible
+- **AND** user presses Back on D-pad or remote
+- **THEN** the control overlay hides
+- **AND** the player does NOT exit
+
+#### Scenario: Back key with UI hidden
+- **WHEN** the player control overlay is hidden
+- **AND** user presses Back on D-pad or remote
+- **THEN** the player exits (standard back navigation)
+
+### Requirement: Fullscreen button hidden on TV
+The fullscreen toggle button in the `TimelineControl` row SHALL NOT be rendered on TV devices (Android TV / Leanback).
+
+#### Scenario: TimelineControl on TV
+- **WHEN** the player control overlay is rendered on a TV device (`FEATURE_LEANBACK`)
+- **THEN** the fullscreen toggle button is not visible
+- **AND** the timestamp text occupies its natural position
+
+### Requirement: Side sheets receive initial focus
+When the speed or resize side sheet opens, focus SHALL be automatically placed on the first selectable item so D-pad users can navigate immediately.

+- **THEN** the speed side sheet appears
+- **AND** focus is on the first speed option (e.g., "2.0X")
+
+#### Scenario: Resize side sheet opens
+- **WHEN** user activates the resize button ("适应") with OK key
+- **THEN** the resize side sheet appears
+- **AND** focus is on the first resize option (e.g., "适应")

+- **AND** focus returns to the main control UI
+
+### Requirement: Auto-hide timer resets on D-pad input
+Any D-pad key event (up, down, left, right, center, back) SHALL reset the player UI auto-hide timer so the UI remains visible while the user is actively navigating with a remote.
+
+#### Scenario: D-pad navigation keeps UI alive
+- **WHEN** the player control UI is visible
+- **AND** user presses any D-pad direction key

+# Player Focus Navigation
+
+## Purpose
+
+Structured D-pad focus navigation for the video player control overlay, enabling predictable focus flow between header, slider, and playback control rows on TV/remote devices. Also covers direction key shortcuts when the control UI is hidden.
+
+## Requirements
+### Requirement: Vertical focus flows between player control rows
+Interactive elements in the video player control overlay SHALL transfer focus in visual row order (header → slider → playback controls) when the user presses up/down on D-pad, regardless of horizontal position differences between elements in adjacent rows.
+
+#### Scenario: Down from header row to slider
+- **WHEN** D-pad focus is on any focusable element in the header row (back button, forward button, or more options button)
+- **THEN** pressing DOWN moves focus to the slider
+
+#### Scenario: Down from slider to playback controls
+- **WHEN** D-pad focus is on the slider
+- **THEN** pressing DOWN moves focus to the play/pause button in the playback control row
+
+#### Scenario: Up from slider to header (TV)
+- **WHEN** D-pad focus is on the slider on a TV device (fullscreen button hidden)
+- **THEN** pressing UP moves focus to the back button in the header row
+
+#### Scenario: Up from slider to fullscreen button (non-TV)
+- **WHEN** D-pad focus is on the slider on a non-TV device (fullscreen button visible)
+- **THEN** pressing UP moves focus to the fullscreen button in the timeline row
+- **AND** default spatial algorithm handles this naturally (fullscreen button sits directly above slider's right side)
+
+#### Scenario: Up from playback controls to slider
+- **WHEN** D-pad focus is on any button in the playback control row
+- **THEN** pressing UP moves focus to the slider
+
+#### Scenario: Horizontal navigation within playback control row
+- **WHEN** D-pad focus is on a button in the playback control row
+- **THEN** pressing LEFT or RIGHT moves focus between buttons within the same row (standard spatial navigation)
+
+### Requirement: Slider D-pad seeking at 10-second step
+When the full control UI is visible and the slider has D-pad focus, LEFT/RIGHT SHALL seek by 10 seconds. The slider's `onKeyEvent` uses `onClick` (not `onValueChange` + `onValueChangeFinished`) so that `isSeeking` is not toggled and the compact overlay stays compact during continuous seek.
+
+#### Scenario: Left on focused slider seeks 10s back
+- **WHEN** D-pad focus is on the slider
+- **AND** the full control UI is visible
+- **THEN** pressing LEFT seeks backward by 10 seconds
+
+#### Scenario: Right on focused slider seeks 10s forward
+- **WHEN** D-pad focus is on the slider
+- **AND** the full control UI is visible
+- **THEN** pressing RIGHT seeks forward by 10 seconds
+
+#### Scenario: Continuous seek via repeated presses
+- **WHEN** D-pad focus is on the slider
+- **AND** the user presses LEFT or RIGHT multiple times in succession
+- **THEN** each press seeks by 10 seconds
+- **AND** the compact overlay remains visible (does not flash to full UI)
+
+#### Scenario: Slider thumb animates on focus
+- **WHEN** D-pad focus enters the slider
+- **THEN** the thumb grows from 15dp to 20dp with animation
+- **AND** a 3dp white border appears around the thumb
+- **AND** the `onFocusChanged` modifier is placed before `.focusable()` so the focus callback fires
+
+### Requirement: Initial focus on control show
+When the player control overlay becomes visible via D-pad input or initial load, focus SHALL be placed on the appropriate control.
+
+#### Scenario: Default focus on initial player load
+- **WHEN** the player first opens
+- **AND** the control UI is visible
+- **THEN** focus is on the play/pause button
+
+#### Scenario: Left key with hidden UI
+- **WHEN** user presses LEFT on D-pad while controls are hidden
+- **THEN** playback seeks backward 10 seconds
+- **AND** a compact overlay appears showing the progress slider and timestamp
+- **AND** the full control overlay (header, playback buttons) does NOT appear
+- **AND** focus is placed on the slider so subsequent LEFT presses continuously seek
+
+#### Scenario: Right key with hidden UI
+- **WHEN** user presses RIGHT on D-pad while controls are hidden
+- **THEN** playback seeks forward 10 seconds
+- **AND** a compact overlay appears showing the progress slider and timestamp
+- **AND** the full control overlay (header, playback buttons) does NOT appear
+- **AND** focus is placed on the slider so subsequent RIGHT presses continuously seek
+
+#### Scenario: Continuous seek from hidden UI
+- **WHEN** user presses LEFT or RIGHT while controls are hidden
+- **AND** then continues pressing LEFT or RIGHT
+- **THEN** each subsequent press seeks by 10 seconds
+- **AND** the compact overlay remains visible
+- **AND** the slider thumb shows focus animation (grow + white border)
+
+#### Scenario: Controls shown via up key
+- **WHEN** user presses UP on D-pad while controls are hidden
+- **THEN** the control overlay becomes visible
+- **AND** focus is placed on the Forward 85s button in the header row
+
+#### Scenario: Controls shown via down key
+- **WHEN** user presses DOWN on D-pad while controls are hidden
+- **THEN** the control overlay becomes visible
+- **AND** focus is placed on the "选集" (episode) text button in the playback control row
+
+#### Scenario: Controls shown via OK/Center key
+- **WHEN** user presses OK/Center on D-pad while controls are hidden
+- **AND** the video is currently playing
+- **THEN** playback pauses
+- **AND** the control overlay becomes visible
+- **AND** focus is placed on the play/pause button
+
+### Requirement: Back key hides player control UI
+When the player control overlay is visible, pressing the Back key SHALL hide the overlay instead of exiting the player.
+
+#### Scenario: Back key with UI visible
+- **WHEN** the player control overlay is visible
+- **AND** user presses Back on D-pad or remote
+- **THEN** the control overlay hides
+- **AND** the player does NOT exit
+
+#### Scenario: Back key with UI hidden
+- **WHEN** the player control overlay is hidden
+- **AND** user presses Back on D-pad or remote
+- **THEN** the player exits (standard back navigation)
+
+### Requirement: Fullscreen button hidden on TV
+The fullscreen toggle button in the `TimelineControl` row SHALL NOT be rendered on TV devices (Android TV / Leanback).
+
+#### Scenario: TimelineControl on TV
+- **WHEN** the player control overlay is rendered on a TV device (`FEATURE_LEANBACK`)
+- **THEN** the fullscreen toggle button is not visible
+- **AND** the timestamp text occupies its natural position
+
+### Requirement: Side sheets receive initial focus
+When the speed or resize side sheet opens, focus SHALL be automatically placed on the first selectable item so D-pad users can navigate immediately.
+
+#### Scenario: Speed side sheet opens
+- **WHEN** user activates the speed button ("倍速") with OK key
+- **THEN** the speed side sheet appears
+- **AND** focus is on the first speed option (e.g., "2.0X")
+
+#### Scenario: Resize side sheet opens
+- **WHEN** user activates the resize button ("适应") with OK key
+- **THEN** the resize side sheet appears
+- **AND** focus is on the first resize option (e.g., "适应")
+
+#### Scenario: Back key closes side sheet
+- **WHEN** a side sheet (speed or resize) is visible
+- **AND** user presses Back
+- **THEN** the side sheet closes
+- **AND** focus returns to the main control UI
+
+### Requirement: Auto-hide timer resets on D-pad input
+Any D-pad key event (up, down, left, right, center, back) SHALL reset the player UI auto-hide timer so the UI remains visible while the user is actively navigating with a remote.
+
+#### Scenario: D-pad navigation keeps UI alive
+- **WHEN** the player control UI is visible
+- **AND** user presses any D-pad direction key
+- **THEN** the auto-hide timer resets
+- **AND** the UI does NOT disappear during active navigation
+
+#### Scenario: Browsing dropdown menu keeps UI alive
+- **WHEN** the MoreVert dropdown menu is open
+- **AND** user presses UP or DOWN to browse menu items
+- **THEN** the auto-hide timer resets
+- **AND** the UI and dropdown menu remain visible

+### Requirement: Slider focus indicated by thumb animation
+The `Slider` component SHALL indicate D-pad focus through thumb animations (size increase + white border). The track colors (play progress, buffered, unplayed) SHALL remain unchanged when focus changes.
+
+#### Scenario: Slider receives D-pad focus

Subject: [PATCH 19/41] fix: player focus bugs + gradient overlay
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix crash when pressing UP/DOWN during compact seek mode (Slider consumed keys unconditionally, now only during isSeeking)
- Fix side sheet overlapping: outer key handler now skips when episode/speed/resize sheets are open
- Fix failure page: retry button now receives initial focus via FocusRequester
- Add player gradient overlay (top/bottom 55% black → 25%/75% transparent)
- Gradient hidden during compact seek mode
- New spec: player-focus-dpad-safety
- Updated spec: player-focus-navigation (side-sheet guard + compact seek exit)
- Updated spec: player-gradient-overlay

+## Context
+
+The video player's focus navigation system was built for the spec-driven `player-focus-navigation` change. It has two code paths:
+
+1. **UI visible** (`isControlUiVisible=true`): Focus flows through the control overlay rows (header → slider → playback) using explicit `focusProperties`.
+2. **UI hidden** (`isControlUiVisible=false`): An outer `.onKeyEvent` handler in `VideoPlayerScreen.kt` intercepts D-pad keys for shortcuts: LEFT/RIGHT → timed seek + compact overlay, UP/DOWN/CENTER → show full UI with targeted focus.
+
+Two bugs exist at the interaction boundary between these paths and other UI states (compact seek mode, side sheets).
+
+## Goals / Non-Goals
+
+**Goals:**
+- Fix the crash when pressing UP/DOWN during compact seek mode (after LEFT/RIGHT with hidden UI)
+- Fix the side-sheet-overlap issue: UP/DOWN should NOT show control UI when episode/speed/resize sheets are open
+- Minimal changes — no new parameters on public APIs unless necessary
+
+**Non-Goals:**
+- Redesigning the focus system architecture
+- Changing the seek behavior or auto-hide timer logic
+- Adding new D-pad shortcuts
+
+## Decisions
+
+### Decision 1: Slider UP/DOWN callback for compact mode exit
+
+**Problem**: During compact seek mode (`isSeeking=true`), `ControlHeader` and `PlaybackControl` are not composed, but the Slider's `focusProperties { up = backFocusRequester; down = playPauseFocusRequester }` still points to those removed `FocusRequester`s. When the user presses UP/DOWN, Compose's focus system tries to navigate to non-existent nodes → crash.
+
+**Options considered**:
+
+| Option | Description | Verdict |
+|--------|-------------|---------|
+| A — Conditional `focusProperties` | Only set `up`/`down` when `!isSeeking` | Rejected: doesn't prevent the focus system from attempting spatial fallback navigation, which could still fail silently |
+| B — Handle in parent `onKeyEvent` | Wrap Slider in Box that intercepts UP/DOWN | Rejected: the Slider's own `onKeyEvent` fires first for UP/DOWN (returning `false`), and the focus system's navigation fires before parent key handlers |
+| C — Add `onDpadUpDown` callback to Slider | Slider consumes UP/DOWN and invokes callback to `showControlUi()` | **Chosen** |
+
+**Rationale**: Option C catches the event at the source (Slider's `onKeyEvent`), consumes it before the focus system gets involved, and triggers `showControlUi()` to exit compact mode gracefully. The callback is a simple `(() -> Unit)?` parameter with a default of `null` — no breaking change to existing Slider callers.
+
+### Decision 2: Side-sheet visibility guard on outer key handler
+
+**Problem**: When a side sheet (episode selector, speed, resize) is opened via `showEpisodeUi()`/`showSpeedUi()`/`showResizeUi()`, these methods call `hideControlUi()` internally → `isControlUiVisible = false`. The outer `.onKeyEvent` handler in `VideoPlayerScreen` only checks `isControlUiVisible`, so it intercepts D-pad keys that should go to the side sheet, calling `showControlUi()` which shows the full control overlay on top of the still-open side sheet.
+
+**Fix**: Add a simple OR guard:
+
+```kotlin
+if (playerState.isControlUiVisible.value ||
+    playerState.isEpisodeUiVisible.value ||
+    playerState.isSpeedUiVisible.value ||
+    playerState.isResizeUiVisible.value) return@onKeyEvent false
+```
+
+This lets keys pass through to the side sheet composables, which handle their own focus navigation and Back key dismissal.
+
+**No alternatives considered**: This is a straightforward missing-condition bug. The check simply needed to account for all UI-visible states, not just `isControlUiVisible`.
+
+## Risks / Trade-offs
+
+- **[Low] Slider API change**: Adding `onDpadUpDown` parameter to the `Slider` composable is backward-compatible (default parameter). Caller in `BottomControlBar` is the only usage in the project.
+- **[Low] Side sheet guard may mask future states**: If new overlay states are added, the guard must be updated. Consider extracting an `isAnyOverlayVisible` computed property in the future.

+## Why
+
+Two focus-related bugs in the video player cause crashes and broken UI states during D-pad navigation: (1) pressing UP/DOWN while in compact seek mode (after LEFT/RIGHT with hidden UI) crashes because Slider's `focusProperties` point to `FocusRequester`s that are not in the composition tree during compact mode, and (2) pressing UP/DOWN while a side sheet (episode selector, speed, resize) is open incorrectly triggers the hidden-UI shortcut handler, showing the full control overlay on top of the still-visible side sheet — creating a confusing double-overlay state.
+
+## What Changes
+
+- **Bug 1 fix**: Prevent UP/DOWN crash during compact seek mode by having the Slider handle UP/DOWN key events to exit compact mode gracefully, instead of relying on `focusProperties` that point to removed composables.
+- **Bug 2 fix**: Guard the hidden-UI D-pad shortcut handler in `VideoPlayerScreen` to not intercept keys when any side sheet (episode/speed/resize) is visible, allowing side sheets to handle their own focus navigation.
+
+## Capabilities
+
+### New Capabilities
+
+- `player-focus-dpad-safety`: Crash-free D-pad navigation during compact seek mode and correct side-sheet-aware key routing
+
+### Modified Capabilities
+
+- `player-focus-navigation`: Hidden-UI shortcut handler must skip UP/DOWN/CENTER when side sheets are visible, and Slider must safely handle UP/DOWN during compact seek mode instead of crashing via dangling focusProperties
+
+## Impact
+
+- `VideoPlayerScreen.kt`: outer `.onKeyEvent` handler (add side-sheet visibility guard)
+- `Slider.kt` or `VideoPlayerControl.kt`: handle UP/DOWN during compact mode (slider's key event or its `focusProperties`)
+- No API changes, no dependency changes, no breaking changes

+
+#### Scenario: UP/DOWN with speed sheet open
+- **WHEN** the playback speed side sheet is open (`isSpeedUiVisible = true`)
+- **AND** the control overlay is hidden

+# Player Focus Navigation (Delta)
+
+## MODIFIED Requirements
+

+- **AND** no side sheet is visible
+- **THEN** playback seeks backward 10 seconds
+- **AND** a compact overlay appears showing the progress slider and timestamp
+- **AND** the full control overlay (header, playback buttons) does NOT appear
+- **AND** focus is placed on the slider so subsequent LEFT presses continuously seek

+## Context
+
+The `video-player` module's `VideoPlayerControl` composable renders a control overlay on top of video content. Currently it uses a uniform `Color.Black.copy(0.2f)` background across the entire overlay. All buttons use `Color.Transparent` as their container color in the normal (unfocused) state, with `Color.White` or `Color.LightGray` for icons and text. This creates a visibility problem against bright/white video content.
+
+The reference implementation [open-ani/animeko](https://github.com/open-ani/animeko) uses `Brush.verticalGradient` in `VideoScaffold.kt` to create dark-to-transparent gradients at the top and bottom edges of the player, providing strong contrast where controls are while keeping the center of the video unobstructed.
+
+The change is scoped to a single file: `VideoPlayerControl.kt` in the `video-player` module.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Replace the uniform overlay background with vertical gradient overlays at the top and bottom
+- Ensure white/LightGray icons and text remain clearly visible against any video content (including pure white frames)
+- Preserve the existing `background` parameter API on `VideoPlayerControl` for callers that override it
+- Keep the center of the video unobstructed and clear
+
+**Non-Goals:**
+- Adding shadows (`Modifier.shadow()`) to individual icons or text — gradients provide sufficient contrast
+- Adding per-button background circles (`Color.Black.copy(0.25f)` on `AdaptiveIconButton`) — not needed with gradient approach
+- Modifying the `app` module's `VideoPlayerScreen.kt` — all changes stay in the library module
+- Changing TV/D-pad focus behavior (focus navigation, inverse colors, focus traversal specs are unaffected)
+
+## Decisions
+
+### Decision 1: Use two `Box` overlays with `Brush.verticalGradient` instead of modifying the uniform `background` parameter
+
+**Rationale**: Animeko's approach uses separate gradient `Box` elements that sit *under* the control UI but *over* the video. This is cleaner than trying to express a gradient through the existing `background: Color` parameter. The existing parameter continues to work for callers that pass it, but the default rendering no longer relies on it.
+
+**Alternatives considered**:
+- *Increase uniform background alpha from 0.2f to 0.5f*: Simpler, but makes the entire overlay darker and looks amateurish.
+- *Add `Modifier.shadow()` to individual buttons/text*: Shadow on circular IconButtons renders as a square shadow (Android Compose limitation). Text shadows help but don't fully solve the problem.
+- *Add semi-transparent circular backgrounds to each `AdaptiveIconButton`*: Works but looks "heavy" — many dark circles scattered across the overlay.
+
+### Decision 2: Use `matchParentSize()` for gradient boxes + `Column` for controls
+
+**Rationale**: Two `Box` composables sized to `matchParentSize()` sit behind the control `Column`. The top box covers the full width/height but only the top ~35% has visible gradient. The bottom box similarly covers only the bottom ~35%. The `Column` with `Spacer(Modifier.weight(1f))` keeps controls at their edge positions without overlap.
+
+```kotlin
+Box(modifier.fillMaxSize()) {
+    // Gradient layers (behind controls)
+    Box(Modifier.matchParentSize().background(topGradient))
+    Box(Modifier.matchParentSize().background(bottomGradient))
+    // Control layers (on top)
+    Column {
+        ControlHeader(...)
+        Spacer(Modifier.weight(1f))
+        BottomControlBar(...)
+    }
+}
+```
+
+### Decision 3: Gradient parameters
+
+Following animeko's lead:
+- **Top gradient**: `0f → Color.Black.copy(0.55f)`, `0.35f → Color.Transparent`
+- **Bottom gradient**: `0f → Color.Transparent`, `0.65f → Color.Transparent`, `1f → Color.Black.copy(0.55f)`
+
+The 0.55f alpha is stronger than the current 0.2f but only applies at the edges. The middle 30% of the screen (where controls don't live) stays fully transparent.
+
+### Decision 4: Keep `AdaptiveIconButton` unchanged
+
+With gradient overlays providing sufficient contrast, `AdaptiveIconButton`'s `Color.Transparent` default container color is fine. TV focus highlighting (`containerColor = primary` when focused) still works on top of the gradient.
+
+## Risks / Trade-offs
+
+- **Gradient colors tuned for dark mode only**: The player currently always uses a dark overlay. If light mode player support is added later, gradients would need inversion. Mitigation: not in scope; the entire player UI assumes dark backgrounds.
+- **Gradient rendering on low-end devices**: `Brush.verticalGradient` on a full-screen `Box` may cause overdraw. Mitigation: gradients are simple 2-3 stop linear gradients; Compose handles these efficiently.
+- **Edge case — very short videos in portrait mode**: In portrait (non-fullscreen), the gradient may cover proportionally more of the video since the video area is shorter. Mitigation: this is acceptable — portrait mode already has limited video real estate, and controls still need contrast.

+## Why
+
+Player control buttons, icons, and text currently render without any background — they appear as pure white or light gray directly on top of video content. When the underlying video frame is bright or white, all controls become nearly invisible. The current uniform `Color.Black.copy(0.2f)` overlay is too faint to provide adequate contrast.
+
+## What Changes
+
+- Replace the uniform semi-transparent black background (`Color.Black.copy(0.2f)`) on the control overlay with **vertical gradient overlays** — a dark-to-transparent gradient at the top and a transparent-to-dark gradient at the bottom
+- Increase effective contrast in the header (title, back button) and playback control areas while keeping the center of the video fully visible
+- Reference implementation: [open-ani/animeko](https://github.com/open-ani/animeko) `VideoScaffold.kt`
+- No API changes; existing `background` parameter on `VideoPlayerControl` remains functional for callers that override it
+
+## Capabilities
+
+### New Capabilities
+- `player-gradient-overlay`: Vertical gradient backgrounds for the video player control overlay's header and footer regions, providing adequate contrast for white icons/text against any video content
+
+### Modified Capabilities
+<!-- None — existing specs (player-focus-navigation, tv-focus-inverse-color, tv-focus-traversal) are unaffected -->
+
+## Impact
+
+- **Module**: `video-player` (`VideoPlayerControl.kt`) — single file change
+- **Breaking**: None — the `background` composable parameter remains available; only its default rendering changes
+- **TV/D-pad**: Focus highlight (primary color on focused buttons) continues to work; focus navigation specs unaffected

+## ADDED Requirements
+
+### Requirement: Player overlay uses vertical gradient backgrounds
+
+The video player control overlay SHALL render vertical gradient backgrounds at the top and bottom edges instead of a uniform semi-transparent background, providing stronger contrast for white icons and text against bright video content while keeping the center of the video fully visible.
+
+#### Scenario: Top gradient provides contrast for header controls
+
+- **WHEN** the player control overlay is visible
+- **THEN** the top edge of the overlay SHALL display a vertical gradient from `Color.Black.copy(0.55f)` at the top to `Color.Transparent` at approximately 35% from the top
+- **AND** the back button, title text, and subtitle text in the header SHALL be clearly visible against any underlying video content
+
+#### Scenario: Bottom gradient provides contrast for playback controls
+
+- **WHEN** the player control overlay is visible
+- **THEN** the bottom edge of the overlay SHALL display a vertical gradient from `Color.Transparent` at approximately 65% from the top to `Color.Black.copy(0.55f)` at the bottom
+- **AND** the playback buttons, timestamp text, slider, and text buttons SHALL be clearly visible against any underlying video content
+
+#### Scenario: Center of video remains unobstructed
+
+- **WHEN** the player control overlay is visible
+- **THEN** the middle portion of the overlay (approximately 35% to 65% from the top) SHALL be fully transparent
+- **AND** the video content in this region SHALL not be dimmed or obscured by the overlay
+
+#### Scenario: Gradient overlay on pure white video frame
+
+- **WHEN** the underlying video content is pure white (#FFFFFF)
+- **AND** the player control overlay is visible
+- **THEN** all control icons and text SHALL be readable with sufficient contrast
+- **AND** no control element SHALL blend into the white background
+
+#### Scenario: Gradient overlay on very dark video frame
+
+- **WHEN** the underlying video content is very dark or black
+- **AND** the player control overlay is visible
+- **THEN** the gradient edges SHALL blend seamlessly with the dark video content
+- **AND** white icons and text SHALL remain clearly visible without appearing overly bright
+
+### Requirement: Existing background parameter remains functional
+
+The `background` parameter on `VideoPlayerControl` SHALL remain in the function signature without breaking changes, ensuring backward compatibility for callers that pass a custom background color.
+
+#### Scenario: Caller passes custom background color
+
+- **WHEN** a caller passes a custom `background` parameter to `VideoPlayerControl`
+- **THEN** the composable SHALL honor the custom background and not render the default gradient overlays
+
+#### Scenario: Caller does not pass background parameter
+
+- **WHEN** a caller invokes `VideoPlayerControl` without overriding the `background` parameter
+- **THEN** the composable SHALL render the default vertical gradient overlays (top and bottom)

+## Requirements
+
+### Requirement: Player overlay uses vertical gradient backgrounds
+
+The video player control overlay SHALL render a vertical gradient background at the top and bottom edges instead of a uniform semi-transparent background, providing stronger contrast for white icons and text against bright video content while keeping the center of the video fully visible.
+
+#### Scenario: Top gradient provides contrast for header controls
+
+- **WHEN** the player control overlay is visible
+- **THEN** the top edge of the overlay SHALL display a vertical gradient from `Color.Black.copy(0.55f)` at the top to `Color.Transparent` at approximately 25% from the top
+- **AND** the back button, title text, and subtitle text in the header SHALL be clearly visible against any underlying video content
+
+#### Scenario: Bottom gradient provides contrast for playback controls
+
+- **WHEN** the player control overlay is visible
+- **THEN** the bottom edge of the overlay SHALL display a vertical gradient from `Color.Transparent` at approximately 75% from the top to `Color.Black.copy(0.55f)` at the bottom
+- **AND** the playback buttons, timestamp text, slider, and text buttons SHALL be clearly visible against any underlying video content
+
+#### Scenario: Center of video remains unobstructed
+
+- **WHEN** the player control overlay is visible
+- **THEN** the middle portion of the overlay (approximately 25% to 75% from the top) SHALL be fully transparent
+- **AND** the video content in this region SHALL not be dimmed or obscured by the overlay
+
+#### Scenario: Gradient overlay on pure white video frame
+
+- **WHEN** the underlying video content is pure white (#FFFFFF)
+- **AND** the player control overlay is visible
+- **THEN** all control icons and text SHALL be readable with sufficient contrast
+- **AND** no control element SHALL blend into the white background
+
+#### Scenario: Gradient overlay on very dark video frame
+
+- **WHEN** the underlying video content is very dark or black
+- **AND** the player control overlay is visible
+- **THEN** the gradient edges SHALL blend seamlessly with the dark video content
+- **AND** white icons and text SHALL remain clearly visible without appearing overly bright
+
+### Requirement: Gradient hidden during seeking
+
+During seeking (D-pad left/right or touch slider drag), the gradient background SHALL be hidden, displaying only the progress slider without any additional overlay.
+
+#### Scenario: Gradient hidden during D-pad seeking
+
+- **WHEN** the control overlay is visible
+- **AND** the user presses D-pad LEFT or RIGHT to seek
+- **THEN** the gradient background SHALL disappear
+- **AND** only the slider SHALL remain visible (compact mode)
+
+#### Scenario: Gradient hidden during touch slider seeking
+
+- **WHEN** the control overlay is visible
+- **AND** the user drags the slider thumb
+- **THEN** the gradient background SHALL disappear
+- **AND** only the slider SHALL remain visible
+
+#### Scenario: Gradient reappears when full UI is shown
+
+- **WHEN** the control overlay is in compact mode (seeking, gradient hidden)
+- **AND** the user taps the screen to show the full control UI
+- **THEN** the gradient background SHALL reappear along with the full control UI

Subject: [PATCH 20/41] fix: slider thumb sub-pixel white ring artifact
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Root cause: .clip(CircleShape) anti-aliased edge pixels blending with gradient overlay
- Second cause: .border(0.dp) still inserts BorderStroke in Skia rendering path
- Fix 1: .background(color, CircleShape) replaces .clip().background() — rasterizes directly as circle
- Fix 2: .then(if active border else Modifier) instead of .border(0.dp)
- Also: reduced active border from 3dp to 2dp
- Spec archived at openspec/changes/archive/2026-07-12-player-slider-thumb-render

+## Requirements
+
+### Requirement: Slider thumb renders without visual artifacts
+
+The slider thumb SHALL render as a clean, solid circle without any visible edge artifacts, regardless of the background behind it.
+
+#### Scenario: Thumb against gradient overlay background
+
+- **WHEN** the player control overlay is visible with its gradient background
+- **AND** the slider thumb is displayed
+- **THEN** the thumb SHALL NOT show any visible sub-pixel white/grey ring around its edge
+- **AND** the thumb SHALL appear as a clean solid circle with smooth edges
+
+#### Scenario: Thumb against transparent background
+
+- **WHEN** the slider is displayed without any background overlay (e.g., compact seek mode)
+- **THEN** the thumb SHALL NOT show any visible ring artifact
+- **AND** the thumb SHALL appear as a clean solid circle
+
+#### Scenario: Thumb rendering is independent of focus state
+
+- **WHEN** the slider thumb is NOT focused and NOT in seeking mode
+- **THEN** the thumb SHALL NOT have any visible border or edge artifact
+- **AND** the thumb SHALL be a solid circle rendered at its base size (15dp)
+
+#### Scenario: Thumb border only appears when active
+
+- **WHEN** the slider is focused OR in seeking mode (isActive = true)
+- **THEN** the thumb SHALL display a 2dp white circular border
+- **AND** when isActive becomes false, the border modifier SHALL be removed entirely from the chain (not set to 0dp)
+- **AND** the border SHALL disappear completely with no residual edge artifact
+
+## Implementation
+
+### Root cause
+
+Two issues combined to produce the visible ring:
+
+1. **Chip anti-aliasing**: `.clip(CircleShape)` followed by `.background(color)` renders the thumb as a color-filled rectangle, then clips it to a circle using an alpha mask. At the circle's edge, GPU anti-aliasing produces semi-transparent pixels. When the background behind the thumb is itself semi-transparent (gradient overlay), these edge pixels blend to produce a visible lighter ring.
+
+2. **zero-width border side effect**: `.border(0.dp, Color.White, CircleShape)` still inserts a `BorderStroke` into the modifier chain, which Skia processes even at zero width — producing a ~1px edge artifact on some rendering paths.
+
+### Fix
+
+Two changes to the thumb modifier chain:
+
+```kotlin
+// Before
+.clip(CircleShape)
+.size(thumbSize)
+.border(if (isActive) 3.dp else 0.dp, Color.White, CircleShape)
+.background(color)
+
+// After
+.size(thumbSize)
+.then(if (isActive) Modifier.border(2.dp, Color.White, CircleShape) else Modifier)
+.background(color, CircleShape)
+```
+
+1. **Remove `.clip(CircleShape)`**: use `.background(color, CircleShape)` instead — Skia rasterizes the background directly as a circle, eliminating the clip alpha-mask pass and its anti-aliasing artifact.
+2. **Conditional border via `.then()`**: skip the border modifier entirely when not active, rather than passing `0.dp`. Also reduced active border from 3dp to 2dp.

+## Context
+
+The video player and long-press context menus have three TV interaction bugs. The most critical is that on tablet devices (Switch OLED, Pixel Tablet emulator), the Back key requires two presses to dismiss player UI because Compose's `OnBackPressedDispatcher` on non-TV devices does not forward `Key.Back` events when focusable elements are in the tree. The other two are missing focus visuals on long-press menus, and an asymmetric D-pad OK button behavior.
+
+### Key finding from investigation
+
+On the tablet emulator (API 35), logcat confirms that `onPreviewKeyEvent` and root `onKeyEvent` both receive the first `Key.Back` press, but `BackHandler` does NOT fire until the second press. This is a Compose platform difference between TV (where `BackHandler` fires immediately) and tablet (where the focus system intercepts the first Back press before the dispatcher).
+
+## Goals / Non-Goals
+
+**Goals:**
+- Single Back press hides player UI on all device types (TV, tablet, phone)
+- Long-press menus in download and favorites screens show focus highlight
+- D-pad OK/Center toggles play/pause when control UI is hidden, mirroring touch double-tap
+
+**Non-Goals:**
+- Changing `hideSystemBars()` behavior (verified unrelated)
+- Refactoring the entire focus or BackHandler system
+- Adding new utility or abstraction files
+
+## Decisions
+
+### Decision 1: Intercept Back key in root `onKeyEvent` instead of fixing `BackHandler`
+
+**Rationale:** The `BackHandler` (via `OnBackPressedDispatcher`) path is unreliable on tablet Compose. The root `onKeyEvent` already has a hidden-UI shortcut handler that checks UI visibility state. Adding Back key handling there is a natural fit — same location, same state checks.
+
+**Priority when multiple UI layers are visible:**
+
+```
+1. Side sheet open?  → close side sheet (speed > resize > episode)
+2. Control UI open?  → hide control UI
+3. Nothing open?     → pass through (→ BackHandler → exit player)
+```
+
+**Alternatives considered:**
+- *Override `dispatchKeyEvent` in Activity*: Too invasive, affects all screens, harder to scope to player only.
+- *Use `onPreviewKeyEvent` instead*: Would consume before focus system, but harder to coordinate with children.
+
+### Decision 2: Use existing `rememberIsFocused()` from `FocusHighlight.kt`
+
+**Rationale:** The `tv-focus-inverse-color` spec already mandates `rememberIsFocused()` as the single source of truth. The download `PopupMenuListItem` and favorites inline menu simply never adopted it. No new abstraction needed.
+
+### Decision 3: Toggle play/pause in OK handler, matching touch double-tap
+
+**Rationale:** The touch double-tap handler in `VideoPlayer.kt:154-159` already implements symmetric toggle. The D-pad OK handler mirrors this: `if playing → pause + show UI`, `if paused → play only (no UI)` — same as touch double-tap which doesn't show controls.
+
+### Decision 4: Key.Menu triggers context menus, not D-pad long-press
+
+**Rationale:** D-pad long-press is unintuitive on remotes/gamepads and behaves inconsistently across TV vs tablet Compose (FLAG_LONG_PRESS fires on Sony TV but not Switch). The `Key.Menu` keycode (82) is the standard Android mechanism for context/overflow actions. Touch long-press via `combinedClickable.onLongClick` is preserved for touchscreen users. Both paths open the same `DropdownMenu`.
+
+### Decision 5: Delete mode for favorites and download detail
+
+**Rationale:** D-pad users need a discoverable way to delete without relying on popup menus.
+A top-bar `OutlinedButton` toggles delete mode. Cards show a centered trash icon
+overlay (visual indicator only). Clicking/D-pad OK on the card body triggers delete.
+Pressing Back in delete mode exits delete mode (does not navigate away).
+Pattern inspired by FongMi/TV (`holder.binding.delete.setVisibility`).
+
+**Behavior:**
+- Top-bar shows `OutlinedButton` with `rememberIsFocused()` + `buttonColors` for proper
+  inverse-color focus highlighting.
+- In delete mode: button shows inverse-color + "Cancel"; each card overlays a centered
+  `Icons.Rounded.Delete` icon at 48dp, semi-transparent.
+- Click/D-pad OK on card body → delete. The trash icon is NOT a separate click target.
+- Back key in delete mode → exits delete mode.
+- Animation: trash icon fades in/out with `AnimatedVisibility`.
+
+### Decision 6: Player starts without control UI
+
+**Rationale:** Showing the control overlay on every launch adds unnecessary visual clutter
+and an extra interaction step. Removing `showControlUi()` in `LaunchedEffect(url)` lets
+playback start with a clean fullscreen view. The control UI still appears on any
+D-pad/touch interaction.
+
+### Decision 7: App exit confirmation dialog
+
+When pressing Back on the home/main screen, show an `AlertDialog` with "确认退出?"
+and two `OutlinedButton` choices ("Cancel" / "OK"). Buttons use `OutlinedButton` +
+`buttonColors` + `rememberIsFocused()` for proper inverse-color focus.
+
+## Risks / Trade-offs
+
+- **Back key consumed in `onKeyEvent` returns `true`**: This means child composables won't see the Back key event. But since the only action needed when UI is visible is "hide UI and move on", this is acceptable. Children that need to handle Back (like text fields) aren't present in the player overlay.
+- **Order-of-operations for Back key intercept**: The intercept logic must check visibility states in the same order as `BackHandler` registration (innermost first). Side sheet checks must come before control UI checks.

+## Why
+
+Multiple TV/handheld interaction bugs degrade the experience. The Back key requires two presses on tablet devices. Long-press context menus (downloads, favorites) lack focus highlighting and don't work reliably with D-pad. The D-pad OK button can't resume playback hidden UI. Context menu actions (delete) have no accessible D-pad alternative. The player control overlay appears on every launch, adding friction.
+
+## What Changes
+
+- **Context menus via Key.Menu**: Keep touch long-press, but use `Key.Menu` (remote) instead of unreliable D-pad long-press for opening popup menus on TV/handheld.
+- **PopupMenu inverse color**: `DropdownMenuItem` in download/favorites menus display `primary`/`onPrimary` focus highlighting.
+- **Player Back key**: Intercept `Key.Back` in root `onKeyEvent` to immediately hide UI on all devices.
+- **D-pad OK toggle**: Hidden UI + OK → playing → pause + show UI; paused → play only.
+- **Delete mode**: Favorites and download detail screens get a "delete" button (top-right). Activating it enters delete mode — clicking a card/row deletes it. Touch long-press + Menu key still available as shortcuts.
+- **Download detail "anime detail" button**: Navigate from download detail back to the anime detail page.
+- **Player starts without control UI**: Remove the `showControlUi()` call on initial load — controls appear only on user interaction (D-pad, touch).
+
+## Capabilities
+
+### New Capabilities
+
+- `player-back-key-intercept`: Intercept Back key at root `onKeyEvent` to dismiss player UI immediately on all device types.
+- `delete-mode`: Favorites and download detail screens support a toggleable delete mode accessible via a top-right button.
+
+### Modified Capabilities
+
+- `tv-focus-inverse-color`: `DropdownMenuItem` in download and favorites menus SHALL display inverse-color focus.
+- `player-focus-navigation`: D-pad OK/Center when UI hidden SHALL toggle play/pause. Player starts playback without showing the control overlay.
+
+## Impact
+
+- `app/.../component/PopupMenuListItem.kt` — remove D-pad long-press, keep Menu key + inverse color
+- `app/.../favourite/FavouriteScreen.kt` — remove D-pad long-press; add delete mode button + logic
+- `app/.../downloaddetail/DownloadDetailScreen.kt` — add delete mode button + anime detail nav button
+- `app/.../videoplayer/VideoPlayerScreen.kt` — Back key intercept, OK toggle
+- `video-player/.../VideoPlayer.kt` — remove `showControlUi()` on initial load; remove debug logging

+## ADDED Requirements
+
+### Requirement: Back key immediately hides player UI on all device types
+When the player control overlay or any side sheet (speed, resize, episode) is visible, pressing the Back key SHALL immediately hide the visible UI component in a single press, regardless of device type (TV, tablet, phone). The Back key SHALL be intercepted at the root `onKeyEvent` level to bypass platform-specific `OnBackPressedDispatcher` behavior differences between TV and tablet Compose implementations.
+
+#### Scenario: Back key hides control UI on tablet
+- **WHEN** the player control overlay is visible on a tablet device
+- **AND** user presses Back on D-pad, remote, or keyboard
+- **THEN** the control overlay hides immediately (single press)
+- **AND** focus is not lost before the UI disappears
+
+#### Scenario: Back key closes side sheet on tablet
+- **WHEN** a side sheet (speed, resize, or episode) is visible on a tablet device
+- **AND** user presses Back on D-pad, remote, or keyboard
+- **THEN** the side sheet closes immediately (single press)
+- **AND** focus is not lost before the UI disappears
+
+#### Scenario: Back key hides control UI on TV
+- **WHEN** the player control overlay is visible on a TV device
+- **AND** user presses Back on D-pad or remote
+- **THEN** the control overlay hides immediately (single press)
+- **AND** existing TV behavior is preserved (no regression)
+
+#### Scenario: Back key closes side sheet on TV
+- **WHEN** a side sheet (speed, resize, or episode) is visible on a TV device
+- **AND** user presses Back on D-pad or remote
+- **THEN** the side sheet closes immediately (single press)
+- **AND** existing TV behavior is preserved (no regression)
+
+### Requirement: Back key interception coexists with BackHandler for exit
+The root `onKeyEvent` intercept for Back key SHALL only consume the event when player UI or side sheets are visible. When all UI is hidden, the Back key SHALL pass through to the existing `BackHandler` which triggers player exit.
+
+#### Scenario: Back key exits player when all UI is hidden
+- **WHEN** all player UI (control overlay, side sheets) is hidden
+- **AND** user presses Back
+- **THEN** the root `onKeyEvent` does NOT consume the Back event
+- **AND** the existing `BackHandler` triggers player exit
+
+#### Scenario: Back key only hides UI when multiple layers are visible
+- **WHEN** both control overlay and a side sheet are visible (side sheet was opened from control overlay)
+- **AND** user presses Back
+- **THEN** the side sheet closes (highest priority)
+- **AND** the control overlay remains hidden (does not reappear)

+## MODIFIED Requirements
+
+### Requirement: DropdownMenuItem receives focus
+All `DropdownMenuItem` instances across the app, including those in long-press context menus (download screen, favorites screen), SHALL display inverse-color focus feedback: `primary` background with `onPrimary`-tinted icon and text when focused via D-pad, keyboard, or TV remote.

+## Context
+
+The project has two focus-tracking utilities in `FocusHighlight.kt`:
+
+| Function | Returns | Touch behavior |
+|----------|---------|---------------|
+| `rememberIsFocused()` | `(isFocused, Modifier)` | No inversion (correct) |
+| `rememberInteractionFocus()` | `(isFocused \|\| isPressed, InteractionSource)` | Inverts color on press (incorrect) |
+
+`rememberInteractionFocus` was created to "prevent visual flash during click" — the idea being that if `containerColor` jumps from `transparent` to `primary` on focus change, pressing first smooths the transition. But this solves a non-problem: M3 buttons already animate color transitions, and `IconButton` has no such flash. The real cost is that touch interactions look wrong — buttons turn primary color on every press instead of showing a ripple.
+
+The main app's `IconButton` usage (HomeScreen, DetailScreen, Settings, etc.) exclusively uses `rememberIsFocused`. Only `rememberInteractionFocus` call sites and the video-player module's inline implementations have this issue.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Eliminate primary color inversion on touch for ALL buttons
+- Single focus-tracking utility: `rememberIsFocused`
+- Delete `rememberInteractionFocus` (no callers remain)
+- Fix `AdaptiveIconButton` and `AdaptiveTextButton` to match
+
+**Non-Goals:**
+- No change to ripple behavior, focus traversal, or D-pad key handling
+- No new utility functions (we already have the right one)
+- No change to `VideoPlayerScreen.kt` failure page button behavior — those M3 `OutlinedButton` call sites already correctly pass `interactionSource`; they just need their `isPressed` logic removed
+
+## Decisions
+
+### Decision 1: Delete `rememberInteractionFocus`, don't deprecate
+
+**Chosen:** Direct deletion after all call sites migrated.
+
+**Rationale:** The function has 12 call sites. After migration, zero callers remain. Deprecation adds noise with no benefit. The function is internal, not a public API.
+
+### Decision 2: Remove `interactionSource` param from M3 buttons
+
+**Chosen:** For `Button`/`OutlinedButton`/`TextButton` call sites, remove the custom `interactionSource`. Use `rememberIsFocused` modifier for focus state.
+
+**Rationale:** M3 buttons create their own default `MutableInteractionSource` when none is passed. The custom source was only needed because `rememberInteractionFocus` exposed `collectIsPressedAsState()` on it. Without press tracking, there's no reason to pass a custom source. The `rememberIsFocused` modifier handles focus tracking independently.
+
+**Alternative considered:** Keep passing `interactionSource` but stop reading `isPressed` from it. Rejected — adds unnecessary complexity; M3's default source works identically for ripple.
+
+### Decision 3: `AdaptiveIconButton` uses `rememberIsFocused` modifier, not inline state
+
+**Chosen:** Add a `focusModifier` parameter to `AdaptiveIconButton`, wired to `rememberIsFocused` at each call site.
+
+**Rationale:** `AdaptiveIconButton` currently tracks focus and press inline. Replacing with `rememberIsFocused` unifies with the rest of the project. The modifier approach (`.onFocusChanged`) is simpler than `MutableInteractionSource` + `collectIsFocusedAsState()`.
+
+**Alternative considered:** Keep `interactionSource` but stop reading `isPressed`. Rejected — adds `MutableInteractionSource` creation + `collectIsFocusedAsState` boilerplate when `Modifier.onFocusChanged` is sufficient.
+
+## Risks / Trade-offs
+
+- **[Risk] M3 Button color jump on focus change without press smoothing** → Mitigation: M3 buttons use `animateColorAsState` internally for smooth transitions. The "flash" concern was theoretical; no actual jank observed in practice with `rememberIsFocused`.
+- **[Trade-off] ~14 files changed for a behavior fix** → The change is mechanical (find-and-replace) across most files. Risk of merge conflicts is low since each file only touches one utility function call.

+## Why
+
+`rememberInteractionFocus()` returns `isActive = isFocused || isPressed`, causing touch interactions to trigger primary color inversion on all M3 buttons (IconButton, TextButton, OutlinedButton, Button). This conflicts with Material3's intended touch behavior (ripple only, no color change). The function is used across 12 call sites in 8 files, while the rest of the project already correctly uses `rememberIsFocused()` (focus-only, ~50 call sites). This creates inconsistent UX between player controls, dialog buttons, and main app buttons.
+
+## What Changes
+
+- Delete `rememberInteractionFocus()` from `FocusHighlight.kt`
+- Replace all 12 `rememberInteractionFocus` calls with `rememberIsFocused`
+- Fix `AdaptiveIconButton` in video-player: remove inline `isPressed` tracking, use `rememberIsFocused`
+- Fix `AdaptiveTextButton` in video-player: remove inline `isPressed` tracking, use `rememberIsFocused`
+- For `Button`/`OutlinedButton`/`TextButton` call sites: remove custom `interactionSource` param (M3 uses its own default source for ripple; focus comes from `rememberIsFocused` modifier instead)
+- Clean up unused `collectIsPressedAsState` imports
+
+## Capabilities
+
+### New Capabilities
+
+- `player-button-press-highlight`: All focusable components use focus-only highlight — touch preserves Material3 default ripple, D-pad focus triggers primary color inversion. Single utility function (`rememberIsFocused`) for the entire project.
+
+### Modified Capabilities
+
+None — this is a new capability establishing a project-wide convention.
+
+## Impact
+
+- **`FocusHighlight.kt`**: delete 1 function (~12 lines)
+- **`VideoPlayerControl.kt`**: `AdaptiveIconButton` + `AdaptiveTextButton` — remove `isPressed`, use `rememberIsFocused` (~15 lines changed)
+- **7 app files**: replace `rememberInteractionFocus` → `rememberIsFocused`, remove `interactionSource` param from M3 buttons (~12 call sites, mostly mechanical find-and-replace)
+- **Imports**: remove `collectIsPressedAsState` where it becomes unused
+- **No API or dependency changes**

+# Player Back Key Intercept
+
+## Purpose
+
+Ensure the Back key immediately dismisses player UI (control overlay and side sheets) on all device types by intercepting Back at the root `onKeyEvent` level, bypassing platform-specific `OnBackPressedDispatcher` behavior differences between TV and tablet Compose implementations.
+
+## Requirements
+
+### Requirement: Back key immediately hides player UI on all device types
+When the player control overlay or any side sheet (speed, resize, episode) is visible, pressing the Back key SHALL immediately hide the visible UI component in a single press, regardless of device type (TV, tablet, phone). The Back key SHALL be intercepted at the root `onKeyEvent` level to bypass platform-specific `OnBackPressedDispatcher` behavior differences between TV and tablet Compose implementations.
+
+#### Scenario: Back key hides control UI on tablet
+- **WHEN** the player control overlay is visible on a tablet device
+- **AND** user presses Back on D-pad, remote, or keyboard
+- **THEN** the control overlay hides immediately (single press)
+- **AND** focus is not lost before the UI disappears
+
+#### Scenario: Back key closes side sheet on tablet
+- **WHEN** a side sheet (speed, resize, or episode) is visible on a tablet device
+- **AND** user presses Back on D-pad, remote, or keyboard
+- **THEN** the side sheet closes immediately (single press)
+- **AND** focus is not lost before the UI disappears
+
+#### Scenario: Back key hides control UI on TV
+- **WHEN** the player control overlay is visible on a TV device
+- **AND** user presses Back on D-pad or remote
+- **THEN** the control overlay hides immediately (single press)
+- **AND** existing TV behavior is preserved (no regression)
+
+#### Scenario: Back key closes side sheet on TV
+- **WHEN** a side sheet (speed, resize, or episode) is visible on a TV device
+- **AND** user presses Back on D-pad or remote
+- **THEN** the side sheet closes immediately (single press)
+- **AND** existing TV behavior is preserved (no regression)
+
+### Requirement: Back key interception coexists with BackHandler for exit
+The root `onKeyEvent` intercept for Back key SHALL only consume the event when player UI or side sheets are visible. When all UI is hidden, the Back key SHALL pass through to the existing `BackHandler` which triggers player exit.
+
+#### Scenario: Back key exits player when all UI is hidden
+- **WHEN** all player UI (control overlay, side sheets) is hidden
+- **AND** user presses Back
+- **THEN** the root `onKeyEvent` does NOT consume the Back event
+- **AND** the existing `BackHandler` triggers player exit
+
+#### Scenario: Back key only hides UI when multiple layers are visible
+- **WHEN** both control overlay and a side sheet are visible (side sheet was opened from control overlay)
+- **AND** user presses Back
+- **THEN** the side sheet closes (highest priority)
+- **AND** the control overlay remains hidden (does not reappear)

+
+## Implementation
+
+### Root cause
+
+`rememberInteractionFocus()` returns `isActive = isFocused || isPressed`, causing ALL component types (IconButton, TextButton, OutlinedButton, Button) to invert colors on touch. This is incorrect — touch should only show Material3 ripple.
+
+### Fix
+
+1. **Replace all `rememberInteractionFocus` calls with `rememberIsFocused`** across 8 files (12 call sites)
+2. **Delete `rememberInteractionFocus`** from `FocusHighlight.kt`
+3. **Fix `AdaptiveIconButton`** in video-player: use `rememberIsFocused` instead of inline `isPressed` tracking
+4. **Fix `AdaptiveTextButton`** in video-player: use `rememberIsFocused` instead of inline `isPressed` tracking
+5. **For `Button`/`OutlinedButton`/`TextButton`**: remove custom `interactionSource` parameter — M3 uses its own default source for ripple; focus state comes from `rememberIsFocused` modifier
+

Subject: [PATCH 23/41] fix: search bar status bar padding and edit/non-edit
 height stability

- Add statusBarsPadding to prevent overlap with system status bar on tablets
- Use onGloballyPositioned to measure InputField height and match non-editing Row
- Add missing BackHandler for non-editing mode (back button works now)
- Fix OK/DirectionCenter key in editing mode to trigger search
- Match Row edge padding (12dp) to InputField internal padding for zero visual jump
- Remove unused imports (SearchBar, rememberSaveable, focusable, AnimeTheme)

+## Context
+
+Animius uses Material 3 theming with three color sources: custom seed color (Catppuccin palette), dynamic color (Material You wallpaper-based), and hardcoded fallback. The `AnimeTheme` composable in `Theme.kt` selects the color scheme based on user preferences, then applies it to `MaterialTheme`. Surface/background colors are generated automatically by M3's tonal palette system, producing tinted grays that some users find undesirable on AMOLED screens.
+
+Current preference flow: `SettingsPreferences` (singleton with `MutableStateFlow` + `SharedPreferences`) → `AnimeTheme` collects state → selects `ColorScheme` → passes to `MaterialTheme`.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Add a toggle that overrides the `background` and `surface` color roles with a flat color (white for light, #121212 for dark)
+- Keep all other M3 color roles (primary, secondary, surfaceVariant, etc.) untouched
+- Maintain full compatibility with dynamic color and custom seed color
+- Use existing `SwitchPref` composable and preference infrastructure
+
+**Non-Goals:**
+- Override `surfaceVariant`, `surfaceContainer`, or other surface-level container colors (future enhancement if requested)
+- Implement AMOLED pure black (#000000) — using #121212 per Material Design dark theme standard
+- Add per-source or per-screen background customization
+
+## Decisions
+
+### 1. Override at `ColorScheme` level via `.copy(background = ..., surface = ...)`
+
+**Decision**: After the color scheme is determined (dynamic or custom seed), apply `scheme.copy(background = ..., surface = ...)` if `pureBackground` is true.
+
+**Rationale**: Clean, composable approach. The override happens at the same level as the scheme selection, keeping the logic centralized. Uses `.let {}` to chain the override after the `when` block.
+
+**Alternatives considered**:
+- Override in a custom `LocalBackgroundColor` composition local → over-engineered for a single color role
+- Modify `getSchemeFromSeed()` to accept a background override → mixes concerns
+
+### 2. Dark background = `#121212` (not pure `#000000`)
+
+**Decision**: Use Material Design's standard dark surface color `0xFF121212`.
+
+**Rationale**: Pure black causes black smearing on OLED panels during scrolling. `#121212` is the established Material Design dark background and is widely recognized as "dark mode" while avoiding visual artifacts.
+
+### 3. No interaction with dynamic color
+
+**Decision**: `pureBackground` only overrides `background`, regardless of whether dynamic color is active. Dynamic color continues to control primary/secondary/tertiary and all other roles.
+
+**Rationale**: Users may want both — Material You accent colors from wallpaper AND a flat background. Forcing mutual exclusion would reduce flexibility.
+
+### 4. Preference stored as Boolean with default `false`
+
+**Decision**: Single boolean toggle, off by default. Named `pureBackground` in code, "黑白背景" in UI.
+
+**Rationale**: Simple on/off matches the feature scope. Default `false` preserves existing behavior for all users.
+
+## Risks / Trade-offs
+
+- **Only `background` and `surface` are overridden** → Cards, chips, and other container elements using `surfaceVariant`, `surfaceContainer*` will still have M3 tinted colors. This may look inconsistent to some users. Mitigation: can be extended to override more surface roles later if requested.
+- **#121212 vs #000000 debate** → Some AMOLED enthusiasts want pure black. Mitigation: #121212 avoids black smearing; can add a "pure AMOLED" option later.
+- **No `onBackground` override** → If the background changes to white/black, the text color (`onBackground`) might not have optimal contrast against M3-generated onBackground. In practice, M3's onBackground is already near-black/near-white, so this should be fine.

+## Why
+
+Many AMOLED users prefer pure black/dark backgrounds for battery savings and visual cleanliness. The current Material 3 theme always applies tinted surfaces (e.g. purple-tinted grays) which some users find distracting. Adding a "黑白背景" toggle lets users opt into flat black/white backgrounds while keeping M3 accent colors intact.
+
+## What Changes
+
+- Add a new preference `pureBackground` (Boolean, default `false`)
+- When enabled:
+  - Light theme: `background` and `surface` colors → `#FFFFFF` (white)
+  - Dark theme: `background` and `surface` colors → `#121212` (Material standard dark)
+- Only the `background` and `surface` color roles are overridden — `surfaceVariant`, accent colors, and all other M3 color roles remain unchanged
+- Does NOT affect dynamic color (Material You) — dynamic color continues to apply to accent colors; only `background` is overridden when this toggle is on
+- Add a toggle switch labeled "黑白背景" in the Appearance settings screen
+
+## Capabilities
+
+### New Capabilities
+- `pure-background`: A toggle in Appearance settings that overrides the M3 background and surface colors with flat black (dark) or white (light), independent of dynamic color and custom theme color.
+
+### Modified Capabilities
+
+## Impact
+
+- **Files modified**:
+  - `util/Preferences.kt` — new `KEY_PURE_BACKGROUND` constant
+  - `util/SettingsPreferences.kt` — new `pureBackground` StateFlow + `changePureBackground()` method
+  - `presentation/theme/Theme.kt` — both `AnimeTheme` overloads accept and apply `pureBackground` override (background + surface)
+  - `presentation/screen/settings/AppearanceScreen.kt` — new `SwitchPref` toggle for the setting
+  - `res/values/strings.xml` — new string resources for label and description
+- **No breaking changes**: default is `false`, existing behavior unchanged
+- **No new dependencies**: uses existing Material Icons `Contrast` icon

+## ADDED Requirements
+
+### Requirement: Pure background preference
+The system SHALL provide a boolean preference `pureBackground` (default `false`) that controls whether the theme background color is overridden with a flat color.
+
+#### Scenario: Default state
+- **WHEN** user has never toggled the pure background setting
+- **THEN** `pureBackground` SHALL be `false` and the M3 generated background color SHALL be used
+
+#### Scenario: Preference persists across app restarts
+- **WHEN** user enables pure background and restarts the app
+- **THEN** pure background SHALL remain enabled
+
+### Requirement: Background and surface color override
+When `pureBackground` is `true`, the system SHALL override the `background` and `surface` color roles of the active `ColorScheme`.
+
+#### Scenario: Light theme with pure background enabled
+- **WHEN** theme mode is Light (or System + device is light) AND `pureBackground` is `true`
+- **THEN** `background` and `surface` colors SHALL be `#FFFFFF` (white)
+
+#### Scenario: Dark theme with pure background enabled
+- **WHEN** theme mode is Dark (or System + device is dark) AND `pureBackground` is `true`
+- **THEN** `background` and `surface` colors SHALL be `#121212`
+
+#### Scenario: Other color roles unchanged
+- **WHEN** `pureBackground` is `true`
+- **THEN** `primary`, `secondary`, `tertiary`, `surfaceVariant`, and all other non-background/surface color roles SHALL remain unchanged from the active color scheme
+
+### Requirement: Dynamic color compatibility
+The pure background setting SHALL NOT interfere with dynamic color (Material You). When both are active, dynamic color determines accent colors while the flat background overrides only the `background` role.
+
+#### Scenario: Dynamic color + pure background
+- **WHEN** `dynamicColor` is `true` AND `pureBackground` is `true` on Android 12+
+- **THEN** primary/secondary/tertiary colors SHALL come from the wallpaper-derived dynamic scheme AND background/surface SHALL be the flat override color
+
+### Requirement: Appearance settings toggle
+The system SHALL display a toggle switch labeled "黑白背景" in the Appearance settings screen with a description explaining the behavior.
+
+#### Scenario: Toggle visibility
+- **WHEN** user opens Appearance settings
+- **THEN** a "黑白背景" toggle SHALL be visible below the dynamic image color toggle
+
+#### Scenario: Toggle interaction
+- **WHEN** user taps the "黑白背景" toggle
+- **THEN** `pureBackground` preference SHALL toggle and the theme background SHALL update immediately without restarting the app

+
+- [x] 2.1 Add `pureBackground` parameter to parameterized `AnimeTheme` in `Theme.kt`
+- [x] 2.2 Apply `.copy(background = ..., surface = ...)` override when `pureBackground` is true (white for light, #121212 for dark)
+- [x] 2.3 Collect `pureBackground` state in no-arg `AnimeTheme` overload and pass to parameterized version
+
+## 3. String Resources (已完成)
+
+- [x] 3.1 Add `pure_background` and `pure_background_description` strings to `res/values/strings.xml`
+
+## 4. Appearance Settings UI (待完成)
+
+- [x] 4.1 Add `Icons.Outlined.Contrast` import to `AppearanceScreen.kt`
+- [x] 4.2 Add `SwitchPref` toggle for "黑白背景" in `AppearanceScreen` below the dynamic image color toggle, wired to `SettingsPreferences.pureBackground` / `changePureBackground()`
+
+## 5. Verification
+
+- [x] 5.1 Build the project with `./gradlew assembleDebug` to verify compilation
+- [ ] 5.2 Test: enable toggle in light mode → background should be white
+- [ ] 5.3 Test: enable toggle in dark mode → background should be #121212
+- [ ] 5.4 Test: enable toggle + dynamic color → accent colors from wallpaper, flat background
+- [ ] 5.5 Test: toggle off → M3 tinted background restored

Subject: [PATCH 26/41] perf: optimize TV card scroll jank with draw-phase
 focus border

- MediaSmall: use Card(onClick) with zero elevation + fixed-width border
  (3dp, color-only change) to eliminate elevation animation and relayout
  on focus change. Release build jank: 7.41% (vs official 7.65%)
- WeekItem: add focus border + zero elevation to ElevatedCard
- build.gradle.kts: fallback to debug signing when release keystore
  env vars are not set

Subject: [PATCH 29/41] feat: darken player gradient overlay & show video
 resolution/bitrate below title
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Increase gradient overlay opacity from 0.55 to 0.75 and extend
  gradient coverage (0.25→0.35 top, 0.75→0.65 bottom) for better
  title readability
- Display video resolution (e.g. 1920×1080) and bitrate (e.g. 5.2Mbps)
  as subtitle line below the title in the player header

Subject: [PATCH 30/41] perf: switch to draw-phase focusBorder using
 Modifier.composed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace composition-phase Modifier.border + rememberIsFocused with
draw-phase focusBorder (drawWithContent + onFocusChanged via
Modifier.composed). Focus state is read only in the draw lambda,
so focus changes trigger draw invalidation only — no recomposition,
no relayout.

- FocusBorder.kt: new draw-phase modifier using composed{}
- MediaSmall.kt: use focusBorder on Card modifier
- WeekScreen.kt: use focusBorder on ElevatedCard modifier
- AnimeDetailScreen.kt: simplify isActive to isFocused only

- 侧栏交互：tab/集数分层（左右切线路保同 index、UP 聚焦当前线路 tab、播放指示跨线路保留）
- 详情页线路选择记忆修复（Room 重发不覆盖用户所选线路）
- 切换剧集/线路失败保留播放器 + 错误浮层可重试；取消上一条加载防竞态
- 播放器：胶囊按钮样式、setLoading 清除播放错误、tab 播放指示、错误/加载圈正确切换

Subject: [PATCH 32/41] refactor: simplify side sheet focus state machine
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- 移除 hasShownOnce：pendingFocusIndex 初始化为 focusIndex，首开/左右切统一由 pending 驱动
- channelFocusRequesters List 改为单个 channelFocusRequester（UP 恒聚焦当前线路 tab）
- 合并侧栏按钮共用样式、错误浮层

Subject: [PATCH 36/41] refactor: consolidate TV focus highlight boilerplate
 and fix MediaSmall border

- Add shared focus helpers (focusedIconButtonColors, focusedTextButtonColors,
  focusedOutlinedButtonColors, FocusedDropdownMenuItem) replacing ~30
  duplicated inline color blocks; convert remaining raw focus state
  boilerplate to rememberIsFocused
- Extract SourceModeMenu (SearchScreen) and DeleteOverlay (Favourite/
  DownloadDetail) shared composables
- Restore MediaSmall onLongClick via combinedClickable, removing the
  hand-rolled pointer long-press hack in FavouriteScreen; keep focusBorder
  outside the clickable layer so the D-pad focus border renders correctly
- Trim unused onLeft/onRight/onEnter params from DpadKeyHandler and dead
  isTv from VideoPlayerControl
- Drop redundant onRefresh/onSourceChanged plumbing (source switch already
  refreshes via isSourceChanged StateFlow)
- Revert ui-tooling to debugImplementation so preview tooling is not
  bundled into release builds

-## Context
-
-`AnimeDetailScreen.kt` and `SearchScreen.kt` already have focus inverse-color effects applied to their buttons using two patterns. The remaining ~40 interactive components across 11 files need the same treatment. The existing spec document (`docs/superpowers/specs/2026-06-27-tv-focus-inverse-color-design.md`) describes both patterns in detail.
-
-Decision: all changes are inline — no shared helper/abstraction files — to minimize review burden for upstream PR acceptance.
-
-## Goals / Non-Goals
-
-**Goals:**
-- Every clickable button-like component in the app shows `primary` background + `onPrimary` content when focused
-- Uniform behavior across all devices (D-pad, keyboard, TV remote; transparent on touch-only)
-- Changes are self-contained in existing files for easy upstream review
-
-**Non-Goals:**
-- New abstraction layers, utility composables, or Modifier extensions
-- Behavior changes for touch interaction
-- Custom focus styling (borders, shadows, scaling) beyond the inverse-color pattern
-- Changes to `MediaSmall` cards (already have border-based focus style — intentional)
-
-## Decisions
-
-### 1. Inline vs shared helper → Inline
-
-**Rationale**: This is destined for an upstream PR. Inline changes are self-explanatory in diff review — the reviewer sees the pattern repeated and trusts it. A shared helper file invites design debate ("why this abstraction?") that could block the PR. Each file's change is ~10 lines and trivially revertible per-component.
-
-### 2. Component-to-pattern mapping
-
-| Component | Pattern | Why |
-|---|---|---|
-| `IconButton` | B (`onFocusChanged`) | No `interactionSource` parameter in Material 3 |
-| `Button` / `OutlinedButton` | A (`interactionSource`) | Has `interactionSource` + `colors` parameters |
-| `TextButton` | A (`interactionSource`) | Same as `Button` — has `interactionSource` + `colors` |
-| `FilledTonalButton` | A (already done) | Has `interactionSource` — already implemented on AnimeDetailScreen |
-| `SuggestionChip` | A (already done) | Has `interactionSource` — already implemented on AnimeDetailScreen |
-| `DropdownMenuItem` | B (`onFocusChanged`) | No `interactionSource` or `colors` parameter |
-| Clickable `Box`/`Row`/`Surface` | B (`onFocusChanged`) | Not a button component — needs manual focus tracking |
-
-### 3. AlertDialog TextButton → also inverse
-
-Even though `AlertDialog` buttons are small and transient, TV users navigate them with D-pad and need clear focus feedback. Same pattern as regular `TextButton`.
-
-### 4. Default unfocused colors → preserve existing
-
-Each component keeps its current default unfocused appearance. The inverse-color effect only activates on focus. This means:
-- `BackTopAppBar` IconButton: default `Color.Transparent`, focus → `primary` bg
-- `OutlinedButton` in WarningMessage: default outlined style, focus → `primary` filled
-- `DropdownMenuItem`: default transparent, focus → `primary` bg with `onPrimary` tinted icon
-
-## Risks / Trade-offs
-
-- **DropdownMenuItem text color**: `DropdownMenuItem` doesn't expose a `colors` parameter. The `text` slot content may need a manual `Text` with conditional color. → Mitigation: wrap text in a custom `Text` that reads the focus state.
-- **SegmentedButton** in AppearanceScreen: Material 3 `SegmentedButton` has limited color customization. → If `colors()` API doesn't support focus state, fall back to Pattern B with modifier-based background.
-- **Compile-time verification only**: No runtime focus tests exist. → Validate on TV emulator with `android layout` after each screen.

-## Why
-
-The focus inverse-color effect (focused button gets `primary` background + `onPrimary` content) is currently only implemented on `AnimeDetailScreen` and `SearchScreen`. On TV/non-touch devices, the remaining ~40 interactive components across the app use default dimming or no visible focus feedback, making D-pad navigation confusing. Users can't easily tell which button is focused.
-
-## What Changes
-
-- Extend focus inverse-color effect to all remaining button-like components across all screens, dialogs, and bottom sheets
-- Cover `IconButton`, `Button`, `OutlinedButton`, `TextButton`, `FilledTonalButton`, `SuggestionChip`, `DropdownMenuItem`, and clickable `Box`/`Row` wrappers
-- Follow the two established patterns already in `AnimeDetailScreen.kt`: Pattern A (`interactionSource` + `collectIsFocusedAsState`) for components with `interactionSource` support, and Pattern B (`onFocusChanged`) for components without it
-- No new abstraction files — all changes are inline in existing composables for easy upstream review
-
-## Capabilities
-
-### New Capabilities
-- `tv-focus-inverse-color`: All interactive components (buttons, chips, menu items, clickable surfaces) across the app display inverse colors (`primary` background, `onPrimary` content) when focused via D-pad/keyboard/TV remote
-
-### Modified Capabilities
-<!-- No existing specs to modify -->
-
-## Impact
-
-- Affected files: ~11 composable files across `presentation/component/` and `presentation/screen/`
-- Shared components (`BackTopAppBar`, `WarningMessage`) — fix once, benefits all screens using them
-- No new dependencies, no architecture changes, no API changes
-- Touch-only devices: zero impact (focus events never fire during touch interaction)

-## ADDED Requirements
-
-### Requirement: Focused button inverse color
-All interactive button-like components across the app SHALL display `primary` background with `onPrimary` content color when focused via D-pad, keyboard, or TV remote.
-
-#### Scenario: IconButton receives focus
-- **WHEN** D-pad navigation focuses an `IconButton`
-- **THEN** the button displays `MaterialTheme.colorScheme.primary` as container color and `MaterialTheme.colorScheme.onPrimary` as content (icon) color
-
-#### Scenario: FilledTonalButton receives focus
-- **WHEN** D-pad navigation focuses a `FilledTonalButton`
-- **THEN** the button displays `primary` background with `onPrimary` text/icon
-
-#### Scenario: SuggestionChip receives focus
-- **WHEN** D-pad navigation focuses a `SuggestionChip`
-- **THEN** the chip displays `primary` background with `onPrimary` label
-
-#### Scenario: TextButton receives focus
-- **WHEN** D-pad navigation focuses a `TextButton` (including in `AlertDialog`)
-- **THEN** the button displays `primary` container color with `onPrimary` content color
-
-#### Scenario: OutlinedButton receives focus
-- **WHEN** D-pad navigation focuses an `OutlinedButton`
-- **THEN** the button displays `primary` filled background with `onPrimary` content, overriding its default outlined appearance
-
-#### Scenario: DropdownMenuItem receives focus
-- **WHEN** D-pad navigation focuses a `DropdownMenuItem`
-- **THEN** the item displays `primary` background with `onPrimary`-tinted icon and text
-
-#### Scenario: Clickable Box/Row receives focus
-- **WHEN** D-pad navigation focuses a clickable `Box`, `Row`, or `Surface`
-- **THEN** the container displays `primary` background with `onPrimary`-tinted content
-
-### Requirement: Focus state includes press state
-For components using Pattern A (`interactionSource`), the active focus visual SHALL include the pressed state to prevent visual flash during click.
-
-#### Scenario: Button pressed while focused
-- **WHEN** user presses (clicks) a focused button
-- **THEN** the button SHALL retain the inverse-color appearance (not revert to default) until the press action completes
-
-### Requirement: Touch interaction unaffected
-Focus inverse-color effects SHALL NOT activate during normal touch interaction on touch-only devices.
-
-#### Scenario: Touch tap on phone
-- **WHEN** user taps a button on a touch-only device (phone, tablet without keyboard/D-pad)
-- **THEN** the button SHALL NOT show the focus inverse-color effect; standard Material 3 ripple/press behavior SHALL be preserved
-
-### Requirement: No new abstraction files
-All focus inverse-color implementations SHALL be inline in existing composable files. No new shared helper composable, Modifier extension, or utility file SHALL be introduced.
-
-#### Scenario: Code review of a single screen
-- **WHEN** an upstream reviewer inspects the diff of any single screen file
-- **THEN** the focus inverse-color logic SHALL be self-contained and understandable within that file without referencing new abstraction layers

-## Context
-
-Animius currently has no shared focus utility layer. Every screen re-implements the same pattern: a `var isFocused by remember { mutableStateOf(false) }` combined with `Modifier.onFocusChanged { isFocused = it.isFocused }` and manual `primary`/`onPrimary` color switching. There are no D-pad interception tools, no focus boundary controls, and no explicit focus order configuration. The project targets `minSdk 26` and already depends on Compose Foundation (which includes `focusProperties`, `focusGroup`, `focusRestorer`, `FocusRequester`, `onKeyEvent`, `onPreviewKeyEvent`). No TV-specific library (`androidx.tv.material3`) is used, and by decision we are not introducing one.
-
-Reference projects studied: `ComposeTv` (uses `handleDPadKeyEvents` modifier + TV M3 components) and `JetStreamCompose` (uses `handleDPadKeyEvents`, `focusOnInitialVisibility`, `FocusRequester.createRefs()` pattern, `bringIntoViewIfChildrenAreFocused`).
-
-## Goals / Non-Goals
-
-**Goals:**
-- Create a minimal set of reusable focus modifiers in `app/.../util/focus/`
-- Fix vertical focus flow on the anime detail page: episodes → episode controls → related
-- Fix vertical focus flow on the appearance settings page: theme mode → (skip color swatches) → switches
-- Replace repetitive per-element `onFocusChanged` boilerplate with a shared `onFocusHighlight` modifier on both screens
-
-**Non-Goals:**
-- Do NOT introduce `androidx.tv.material3` or any new external dependency
-- Do NOT change the visual appearance of focus states (inverse-color pattern stays)
-- Do NOT modify the player screen (separate change)
-- Do NOT refactor other screens (Home, Search, Week, Favourite, Danmaku settings) — they can adopt the utilities later
-- Do NOT implement a full `focusOrder` DSL — start with direction-key interception where needed
-
-## Decisions
-
-### Decision 1: Three utility modifiers, not one unified system
-
-**Chosen:** Three independent modifier files under `app/.../util/focus/`:
-- `FocusHighlight.kt` — replaces `onFocusChanged` + manual color state boilerplate
-- `DpadKeyHandler.kt` — `handleDPadKeyEvents` for direction-key interception
-- `FocusOrder.kt` — thin helpers for `focusProperties` configuration
-
-**Rejected:** A full `FocusManager` Composable wrapper or a `Box`-level focus interceptor. Too heavy for the current needs. These three modifiers address the concrete problems and compose freely.
-
-**Rationale:** Matches the pattern both ComposeTv and JetStreamCompose use — standalone modifier extensions, not a wrapping component. Easy to test, easy to adopt incrementally.
-
-### Decision 2: `handleDPadKeyEvents` uses `onPreviewKeyEvent` for UP/DOWN/LEFT/RIGHT, not `onKeyEvent`
-
-**Chosen:** `onPreviewKeyEvent` (fires before child composables process the event).
-
-**Rejected:** `onKeyEvent` (fires after children).
-
-**Rationale:** When we want to intercept a direction key at a boundary (e.g., skip over ColorBall on ↑↓), we need to consume the event *before* any child inside ColorBall has a chance to receive it. `onPreviewKeyEvent` gives us this priority. Events that should pass through (e.g., ← → within ColorBall) return `false` to let children handle them.
-
-This matches the ComposeTv and JetStreamCompose implementations.
-
-### Decision 3: Detail page — EpisodeListControl becomes a standalone Row
-
-**Current layout:**
-```
-Box {
-    AnimeEpisodes(LazyRow, full-width)
-    EpisodeListControl(floated: Modifier.align(BottomEnd))
-}
-```
-
-**New layout:**
-```
-Column {
-    AnimeEpisodes(LazyRow, full-width)
-    EpisodeListControl(Row, right-aligned, full-width)
-}
-```
-
-The `Box` wrapping is replaced with `Column`. `EpisodeListControl` moves from `Modifier.align(Alignment.BottomEnd)` + `offset(y = ...)` to a simple `Row(horizontalArrangement = Arrangement.End)` inside the `Column`. This creates a proper vertical stacking so Compose's spatial algorithm naturally moves focus: episodes ↔ controls ↔ related.
-
-The visual appearance is preserved because `EpisodeListControl` was already right-aligned; the only change is its Y position (slightly adjusted from the previous offset-based positioning).
-
-### Decision 4: Settings page — ColorBall uses horizontal-only focus with vertical interception
-
-**Approach:** Wrap `ColorBall`'s `LazyRow` in a `Box` with `handleDPadKeyEvents(onUp = { ... }, onDown = { ... })` that manually routes ↑↓ focus past the entire row.
-
-```
-Box(
-    modifier = Modifier.handleDPadKeyEvents(
-        onUp = { themeModeFocusRequester.requestFocus() },
-        onDown = { dynamicColorSwitchFocusRequester.requestFocus() }
-    )
-) {
-    ColorBall LazyRow(...)
-}
-```
-
-Individual color circles inside ColorBall still use standard ← → navigation within the row. The outer Box intercepts ↑↓ before they reach any child.
-
-**Alternative considered:** `focusProperties { up = Cancel; down = Cancel }` on each circle. Rejected because it blocks vertical movement entirely without providing a target — the focus system would do nothing on ↑↓, which is worse UX than the current random-jump behavior.
-
-### Decision 5: Focus highlight stays inline, not extracted from individual screens yet
-
-The `FocusHighlight` modifier will be used on the two target screens (detail, settings). Other screens (Home, Search, Week, Favourite) keep their existing manual `onFocusChanged` patterns. They can be migrated later as a follow-up refactor. This keeps the change focused and minimizes regression risk.
-
-### Decision 6: Package structure
-
-```
-app/src/main/java/com/lanlinju/animius/util/focus/
-├── FocusHighlight.kt      # rememberIsFocused()
-├── DpadKeyHandler.kt      # Modifier.handleDPadKeyEvents()
-```
-
-Two files at package `com.lanlinju.animius.util.focus`. No new module — stays in `:app`.
-
-### Decision 7 (v4 — 彻底重构): 放弃 lastPlayedFocusRef，改用 moveFocus
-
-**问题:** 在 LazyRow item 内部用 `LaunchedEffect` 管理 `lastPlayedFocusRef` 产生了一系列
-时序问题：异步窗口期崩溃、倒序后 ref 失效、正序后 `initialFocusDone` 重置导致抢焦点。
-经过 v1-v3 迭代修复均未彻底解决。
-
-**新方案:** 完全放弃 `lastPlayedFocusRef` 机制。
-
-1. `AnimeEpisodes` 不再接收 `lastPlayedFocusRef` 参数
-2. `EpisodeListControl.onUpFocusRequest` 改为 `focusManager.moveFocus(FocusDirection.Up)`
-   — 让 Compose 空间算法自然向上导航到 LazyRow 中空间最近的 episode
-3. `FavouriteIcon.onDown` 同样改为 `focusManager.moveFocus(FocusDirection.Down)`
-4. 初始 focus：`AnimeEpisodes` 函数级别用 `LaunchedEffect(Unit)` 滚动到 `lastPosition`
-   并 `requestFocus` 第一个可见 item（通过 `scrollState.firstVisibleItemIndex` 获取）
-5. 倒序后焦点留在按钮上（不抢），按↑时 `moveFocus(Up)` 自然导航
-
-**优势:**
-- 无 FocusRequester 生命周期问题（不存储跨 composable 引用）
-- 无异步时序窗口
-- 倒序/正序切换不抢焦点
-- `moveFocus` 是 Compose 原生 API，稳定可靠
-
-**代价:**
-- 按↑从控件行到集数时，聚焦到空间最近的 episode（不一定是最后播放的）
-- 但 LazyRow 已滚动到 `lastPosition` 附近，所以空间最近的通常就是最后播放的
-
-### Decision 8: Reverse list button shows toggle state
-
-**Chosen:** Change button text based on current `reverseList` state.
-When `reverseList` is `false`, show the string resource `reverse_list` ("列表倒序").
-When `reverseList` is `true`, show "列表正序". No new string resource needed —
-hardcoded Chinese literal since other UI text in this row ("线路", "更多") is also hardcoded.
-
-## Risks / Trade-offs
-
-| Risk | Mitigation |
-|------|------------|
-| `handleDPadKeyEvents` with `onPreviewKeyEvent` may conflict with existing `onKeyEvent`/`onPreviewKeyEvent` modifiers on the same composable | Read current code for each usage site; only install the modifier where no existing key handler is present |
-| `FocusRequester.requestFocus()` calls from `handleDPadKeyEvents` may fail if the target composable is not yet composed (scrolled off-screen, conditional) | Verify target composables are always in the composition tree when the direction-key callback fires. Detail page elements (episodes, controls, related) are always visible together |
-| Animation-driven `ColorBall` uses `animateDpAsState` — focus border animation may conflict with focus highlight | `onFocusChanged` already exists on `ColorBall` items; replacing with `onFocusHighlight` preserves the same triggers |
-| Changing EpisodeListControl from Box-floating to Column-row shifts the vertical layout slightly | Trivial Y-offset difference; visually negligible since EpisodeListControl was tiny and already near the LazyRow bottom |

-## Why
-
-D-pad focus navigation on the anime detail page and apperance settings page produces unpredictable jump targets. Users pressing down from an episode button land on related anime cards instead of the episode control row (channel/reverse/more), and pressing up from settings toggles lands on a random color swatch mid-row instead of the theme mode selector. The root cause is Compose's default 2D spatial focus algorithm making decisions based on geometric proximity in layouts where elements overlap or span different horizontal widths — the spatially "closest" item is not the logically "next" item.
-
-## What Changes
-
-- **New focus utility toolkit** (`app/.../util/focus/`): A set of lightweight Compose modifiers that layer on top of existing Compose focus APIs (no new library dependency). Includes `onFocusHighlight` (replaces repetitive manual `onFocusChanged` + color switching), and `handleDPadKeyEvents` (direction-key interception for custom navigation boundaries).
-- **Detail page layout refactor**: `EpisodeListControl` moved from a floating `Box(Alignment.BottomEnd)` overlay into an independent row below the episodes `LazyRow`, establishing a clean vertical flow: episodes → controls → related.
-- **Settings page focus boundaries**: `ColorBall` color swatch row configured to only accept horizontal focus traversal (← →), so vertical ↑↓ from the switches below skips over the entire swatch row and lands on the theme mode selector.
-- **Consistent focus highlight style**: All interactive elements on both screens use the shared `onFocusHighlight` modifier instead of per-element `onFocusChanged` boilerplate.
-
-## Capabilities
-
-### New Capabilities
-
-- `tv-focus-traversal`: Predictable vertical and horizontal focus flow for complex layouts where items span different widths or overlap. Covers D-pad navigation boundaries, custom direction interception, and focus group isolation.
-
-### Modified Capabilities
-
-None — this change improves existing focus behavior without altering the visual focus style contract defined in `tv-focus-inverse-color`.
-
-## Impact
-
-- **New files**: `app/.../util/focus/` package (~3 files: `FocusHighlight.kt`, `DpadKeyHandler.kt`, `FocusOrder.kt`)
-- **Modified files**: `AnimeDetailScreen.kt` (layout restructure + adopt shared focus modifiers), `AppearanceScreen.kt` (ColorBall focus isolation + adopt shared modifiers)
-- **No API changes**: Public composable signatures unchanged
-- **No new dependencies**: Uses only `androidx.compose.ui.focus.*` and `androidx.compose.ui.input.key.*` already in the project
-- **No behavior change for touch/mouse users**: Focus modifiers only affect D-pad/keyboard navigation

-## ADDED Requirements
-
-### Requirement: Vertical focus flows through layout rows in order
-Interactive elements in vertically stacked layouts (Column or scrollable equivalent) SHALL transfer focus in visual row order when the user presses up/down on D-pad, regardless of horizontal position differences between elements in adjacent rows.
-
-#### Scenario: Episodes row to controls row (detail page)
-- **WHEN** D-pad focus is on any episode button in the episodes `LazyRow`
-- **THEN** pressing DOWN moves focus to the first focusable item in the `EpisodeListControl` row directly below
-- **AND** pressing UP moves focus to the control above the episodes row
-
-#### Scenario: Controls row to related row (detail page)
-- **WHEN** D-pad focus is on any control button (channel, reverse, or more episodes)
-- **THEN** pressing DOWN moves focus to the first item in the related anime `LazyRow`
-- **AND** pressing UP moves focus to the last played episode button in the row above
-
-#### Scenario: Favourite button to last played episode (detail page)
-- **WHEN** D-pad focus is on the FavouriteIcon (heart button)
-- **THEN** pressing DOWN moves focus to the last played episode button
-
-#### Scenario: Reverse list preserves last played focus (detail page)
-- **WHEN** user toggles reverse list
-- **AND** presses UP from EpisodeListControl
-- **THEN** focus moves to the last played episode button (not a different episode)
-
-#### Scenario: Theme mode to switch rows (settings page)
-- **WHEN** D-pad focus is on a theme mode `SegmentedButton` (System, Light, or Dark)
-- **THEN** pressing DOWN moves focus to the first focusable item below the color swatch row (the Dynamic Color switch)
-- **AND** pressing UP moves focus to an element above the theme mode row
-
-### Requirement: Color swatch row accepts only horizontal focus traversal
-The `ColorBall` color swatch `LazyRow` in the appearance settings SHALL only accept horizontal (←/→) focus movement. Vertical (↑/↓) key events originating from within the swatch row SHALL be intercepted and redirected to the logical row above or below.
-
-#### Scenario: Vertical key intercepted inside color swatch row
-- **WHEN** D-pad focus is on any color circle inside the `ColorBall` LazyRow
-- **THEN** pressing UP moves focus to the theme mode `SegmentedButtonRow` above
-- **AND** pressing DOWN moves focus to the Dynamic Color `SwitchPref` below
-- **AND** pressing LEFT or RIGHT navigates between color circles within the row (standard behavior)
-
-#### Scenario: Entering the color swatch row from above
-- **WHEN** D-pad focus is on the theme mode selector
-- **AND** user presses RIGHT (or final → moves focus right)
-- **THEN** focus enters the `ColorBall` LazyRow at the first visible color circle
-
-#### Scenario: Exiting the color swatch row to below
-- **WHEN** D-pad focus is on the rightmost color circle in the `ColorBall` LazyRow
-- **AND** user presses RIGHT
-- **THEN** focus moves to the Dynamic Color `SwitchPref` below (or wraps to the next logical control)
-
-### Requirement: Focus highlight uses a shared inverse-color modifier
-All interactive elements SHALL use `Modifier.onFocusHighlight()` instead of requiring per-element `var isFocused by remember` + `Modifier.onFocusChanged` boilerplate. The modifier SHALL apply `primary` background and `onPrimary` content color when the element is focused, matching the existing focus style convention.
-
-#### Scenario: Applying focus highlight to a button
-- **WHEN** a composable uses `Modifier.onFocusHighlight(containerColor = true, contentColor = true)`
-- **AND** the composable receives D-pad focus
-- **THEN** the composable's container displays `MaterialTheme.colorScheme.primary`
-- **AND** its content displays `MaterialTheme.colorScheme.onPrimary`
-
-#### Scenario: Focus highlight with no color change
-- **WHEN** a composable uses `Modifier.onFocusHighlight()` without setting custom colors
-- **AND** the composable receives D-pad focus
-- **THEN** no visual change occurs (the modifier is a no-op — used as a focus-tracking anchor without UI changes)
-
-### Requirement: D-pad direction keys can be intercepted at layout boundaries
-The `Modifier.handleDPadKeyEvents()` extension SHALL allow composables to intercept and handle D-pad direction events (up/down/left/right/enter) before child composables process them, using `onPreviewKeyEvent` priority.
-
-#### Scenario: Intercepting a down press at a vertical boundary
-- **WHEN** a composable uses `Modifier.handleDPadKeyEvents(onDown = { customAction() })`
-- **AND** the composable (or any child) has focus
-- **AND** user presses D-pad DOWN
-- **THEN** `customAction()` is invoked
-- **AND** the key event is consumed (not propagated to children)
-
-#### Scenario: Passing through a non-intercepted direction
-- **WHEN** a composable uses `Modifier.handleDPadKeyEvents(onDown = { ... })` without setting `onLeft`
-- **AND** user presses D-pad LEFT
-- **THEN** the left key event is NOT consumed and propagates to child composables normally

-## Context
-
-The `tv-focus-inverse-color` change introduced focus highlighting across ~40 interactive components in 13 files. It used two repetition patterns:
-
-- **Pattern B** (`onFocusChanged` + `mutableStateOf`): Used for `IconButton`, `DropdownMenuItem`, clickable `Surface`/`Box`. ~40 instances.
-- **Pattern A** (`MutableInteractionSource` + `collectIsFocusedAsState` + `collectIsPressedAsState`): Used for `Button`, `OutlinedButton`, `TextButton`. ~25 instances.
-
-A `rememberIsFocused()` utility already exists in `util/focus/FocusHighlight.kt` (created by `detail-settings-focus-fixes`) and covers Pattern B. `AppearanceScreen` already uses it. All other files still use inline boilerplate.
-
-No utility exists for Pattern A.
-
-## Goals / Non-Goals
-
-**Goals:**
-- Add `rememberInteractionFocus()` to `FocusHighlight.kt` covering Pattern A
-- Migrate all 13 files from inline focus patterns to the two shared functions
-- Delete ~345 lines of duplicated boilerplate
-- Zero behavioral or visual change — same focus colors, same pressed-state handling, same Compose APIs
-
-**Non-Goals:**
-- Do NOT extract `MediaSmall` Card border (different visual pattern)
-- Do NOT extract `NavigationBar` item focus (compound `selected || isFocused` condition)
-- Do NOT extract `Slider` D-pad + thumb animation (too specialized)
-- Do NOT extract `GridLayoutTab` three-state focus
-- Do NOT extract `VideoPlayerControl.AdaptiveIconButton` (already a shared component)
-- Do NOT create a `FocusManager` or wrapper composable — stick to modifier-level utilities
-
-## Decisions
-
-### Decision 1: `rememberInteractionFocus()` returns `Pair<Boolean, MutableInteractionSource>`
-
-**Chosen:** `Pair<Boolean, MutableInteractionSource>` — the boolean is `isActive = isFocused || isPressed`, already resolved.
-
-**Rejected:** Returning `Triple<Boolean, Boolean, MutableInteractionSource>` with separate `isFocused` and `isPressed` values. No call site uses them separately — all combine them into `isActive`.
-
-**Rationale:** Every existing use follows the same pattern: `val isActive = isFocused || isPressed`. Returning the pre-combined boolean saves a line at every call site.
-
-### Decision 2: Two separate functions, not one merged
-
-**Chosen:** `rememberIsFocused()` (Pattern B) and `rememberInteractionFocus()` (Pattern A) as separate functions.
-
-**Rejected:** A single function with a boolean parameter (`withPress = true`). This would create two code paths in one function, making it harder to read at call sites.
-
-**Rationale:** The two patterns serve different component families. Pattern A needs `interactionSource` to pass to `Button`/`OutlinedButton`; Pattern B only needs a `Modifier`. Keeping them separate makes intent explicit at the call site.
-
-### Decision 3: What components are NOT migrated
-
-The following have sufficiently unique focus behavior that extracting them would obscure, not clarify:
-
-| Component | Reason to keep inline |
-|---|---|
-| `MediaSmall` Card | Focus adds a `border()`, not background color — completely different visual pattern |
-| `NavigationBar` items | Has `selected \|\| isFocused` compound condition + `NavigationBarItemDefaults.colors()` — combining with `rememberIsFocused()` would add confusion, not reduce it |
-| `Slider` (video-player) | Focus triggers D-pad key handling + thumb size animation + white border + `pointerInput` — logic is specific to one component |
-| `GridLayoutTab` (HomeScreen) | Three-state: `isFocused` / `selected` / `default` with different colors for each — no other component shares this pattern |
-| `VideoPlayerControl.AdaptiveIconButton` | Already a shared internal component with built-in Pattern A — no migration needed |
-
-### Decision 4: Use destructuring `val (x, y)` syntax
-
-**Chosen:** `val (isFocused, focusModifier) = rememberIsFocused()`
-
-**Rejected:** `val focusState = rememberIsFocused()` then `focusState.first` / `focusState.second`. Less readable.
-
-**Rationale:** Kotlin's destructuring makes the intent clear. The function name already signals what it returns; destructuring names reinforce it.
-
-## Risks / Trade-offs
-
-- **[Risk] Merge conflicts with upstream**: The original author may have their own changes in affected files. → **Mitigation**: This is a pure refactor — every change is a mechanical replacement. If conflicts arise, reverting the refactor is trivial: re-apply the inline pattern at the conflicted site.
-- **[Risk] Spec requirement change**: The original `tv-focus-inverse-color` spec includes "No new abstraction files". → **Mitigation**: This change includes a MODIFIED requirement replacing it with "Shared focus utilities preferred". The delta spec documents the rationale.

-## Why
-
-~450 lines of identical focus boilerplate copied across 13 files — two patterns (`onFocusChanged` + `mutableStateOf` and `MutableInteractionSource` + `collectIsFocusedAsState` + `collectIsPressedAsState`) repeated ~65 times. A `rememberIsFocused()` utility already exists in `util/focus/FocusHighlight.kt` but only `AppearanceScreen` uses it. The Button-family pattern (`rememberInteractionFocus()`) has no shared utility at all. Every new button added to any screen copies the same 4-8 lines of boilerplate, risking typos and inconsistency.
-
-The "No new abstraction files" constraint from the original `tv-focus-inverse-color` spec was well-intentioned (keep diffs self-contained for upstream PR review) but has produced the exact opposite outcome: every file carries a large, repetitive diff that obscures the actual UI changes. A 10-line shared utility reduces each screen's diff to 1-2 lines, making upstream review easier, not harder.
-
-## What Changes
-
-- Add `rememberInteractionFocus()` to `util/focus/FocusHighlight.kt` — replaces the `MutableInteractionSource` + `collectIsFocusedAsState` + `collectIsPressedAsState` + `isActive` chain in Button-family components
-- Migrate all 13 files from inline focus patterns to `rememberIsFocused()` / `rememberInteractionFocus()`
-- Remove ~345 lines of duplicated boilerplate
-- Replace "No new abstraction files" spec requirement with "Shared focus utilities preferred"
-
-## Capabilities
-
-### Modified Capabilities
-
-- `tv-focus-inverse-color`: Replace "No new abstraction files" requirement with "Shared focus utilities preferred" — the visual behavior (primary/onPrimary on focus) is unchanged, but the implementation pattern shifts from per-file inline boilerplate to shared `util/focus/FocusHighlight.kt` utilities.
-
-## Impact
-
-- **Modified files**: 14 files — 1 util file (+10 lines) + 13 screen/component files (~-345 lines net)
-- **Behavior change**: None. Same Compose APIs, same runtime focus → color mapping
-- **No new dependencies**: Uses existing `androidx.compose.foundation.interaction` and `androidx.compose.ui.focus` APIs already in the project
-- **Upstream PR**: Per-screen diffs shrink significantly; shared utility is self-documenting and reviewable once

-## MODIFIED Requirements
-
-### Requirement: No new abstraction files
-Focus inverse-color implementations SHALL use shared utility functions from `util/focus/FocusHighlight.kt` rather than inline per-element boilerplate. New interactive components SHALL adopt `rememberIsFocused()` (for `IconButton`, `DropdownMenuItem`, clickable surfaces) or `rememberInteractionFocus()` (for `Button`, `OutlinedButton`, `TextButton`) instead of re-implementing `onFocusChanged` + `mutableStateOf` or `MutableInteractionSource` + `collectIsFocusedAsState` + `collectIsPressedAsState`.
-
-The two utility functions (`rememberIsFocused()` and `rememberInteractionFocus()`) SHALL be the single source of truth for focus state tracking. When a bug is found in focus state logic, it SHALL be fixed once in the utility file, not in each screen.
-
-#### Scenario: Adding a new IconButton with focus
-- **WHEN** a developer adds a new `IconButton` to any screen that needs D-pad focus highlighting
-- **THEN** they SHALL use `val (isFocused, focusModifier) = rememberIsFocused()` and attach `focusModifier` to the button, reading `isFocused` for `containerColor` and `contentColor`
-- **AND** they SHALL NOT write a new `mutableStateOf(false)` + `onFocusChanged` block
-
-#### Scenario: Adding a new TextButton with focus
-- **WHEN** a developer adds a new `TextButton` to any screen that needs D-pad focus highlighting
-- **THEN** they SHALL use `val (isActive, interactionSource) = rememberInteractionFocus()` and pass `interactionSource` to the button, reading `isActive` for colors
-- **AND** they SHALL NOT write a new `MutableInteractionSource` + `collectIsFocusedAsState` + `collectIsPressedAsState` block
-
-#### Scenario: Code review of a single screen
-- **WHEN** an upstream reviewer inspects the diff of any single screen file
-- **THEN** the focus inverse-color logic SHALL reference `rememberIsFocused()` or `rememberInteractionFocus()` from `util/focus/FocusHighlight.kt`, which is self-documenting and reviewable once

-## Context
-
-The video player's focus navigation system was built for the spec-driven `player-focus-navigation` change. It has two code paths:
-
-1. **UI visible** (`isControlUiVisible=true`): Focus flows through the control overlay rows (header → slider → playback) using explicit `focusProperties`.
-2. **UI hidden** (`isControlUiVisible=false`): An outer `.onKeyEvent` handler in `VideoPlayerScreen.kt` intercepts D-pad keys for shortcuts: LEFT/RIGHT → timed seek + compact overlay, UP/DOWN/CENTER → show full UI with targeted focus.
-
-Two bugs exist at the interaction boundary between these paths and other UI states (compact seek mode, side sheets).
-
-## Goals / Non-Goals
-
-**Goals:**
-- Fix the crash when pressing UP/DOWN during compact seek mode (after LEFT/RIGHT with hidden UI)
-- Fix the side-sheet-overlap issue: UP/DOWN should NOT show control UI when episode/speed/resize sheets are open
-- Minimal changes — no new parameters on public APIs unless necessary
-
-**Non-Goals:**
-- Redesigning the focus system architecture
-- Changing the seek behavior or auto-hide timer logic
-- Adding new D-pad shortcuts
-
-## Decisions
-
-### Decision 1: Slider UP/DOWN callback for compact mode exit
-
-**Problem**: During compact seek mode (`isSeeking=true`), `ControlHeader` and `PlaybackControl` are not composed, but the Slider's `focusProperties { up = backFocusRequester; down = playPauseFocusRequester }` still points to those removed `FocusRequester`s. When the user presses UP/DOWN, Compose's focus system tries to navigate to non-existent nodes → crash.
-
-**Options considered**:
-
-| Option | Description | Verdict |
-|--------|-------------|---------|
-| A — Conditional `focusProperties` | Only set `up`/`down` when `!isSeeking` | Rejected: doesn't prevent the focus system from attempting spatial fallback navigation, which could still fail silently |
-| B — Handle in parent `onKeyEvent` | Wrap Slider in Box that intercepts UP/DOWN | Rejected: the Slider's own `onKeyEvent` fires first for UP/DOWN (returning `false`), and the focus system's navigation fires before parent key handlers |
-| C — Add `onDpadUpDown` callback to Slider | Slider consumes UP/DOWN and invokes callback to `showControlUi()` | **Chosen** |
-
-**Rationale**: Option C catches the event at the source (Slider's `onKeyEvent`), consumes it before the focus system gets involved, and triggers `showControlUi()` to exit compact mode gracefully. The callback is a simple `(() -> Unit)?` parameter with a default of `null` — no breaking change to existing Slider callers.
-
-### Decision 2: Side-sheet visibility guard on outer key handler
-
-**Problem**: When a side sheet (episode selector, speed, resize) is opened via `showEpisodeUi()`/`showSpeedUi()`/`showResizeUi()`, these methods call `hideControlUi()` internally → `isControlUiVisible = false`. The outer `.onKeyEvent` handler in `VideoPlayerScreen` only checks `isControlUiVisible`, so it intercepts D-pad keys that should go to the side sheet, calling `showControlUi()` which shows the full control overlay on top of the still-open side sheet.
-
-**Fix**: Add a simple OR guard:
-
-```kotlin
-if (playerState.isControlUiVisible.value ||
-    playerState.isEpisodeUiVisible.value ||
-    playerState.isSpeedUiVisible.value ||
-    playerState.isResizeUiVisible.value) return@onKeyEvent false
-```
-
-This lets keys pass through to the side sheet composables, which handle their own focus navigation and Back key dismissal.
-
-**No alternatives considered**: This is a straightforward missing-condition bug. The check simply needed to account for all UI-visible states, not just `isControlUiVisible`.
-
-## Risks / Trade-offs
-
-- **[Low] Slider API change**: Adding `onDpadUpDown` parameter to the `Slider` composable is backward-compatible (default parameter). Caller in `BottomControlBar` is the only usage in the project.
-- **[Low] Side sheet guard may mask future states**: If new overlay states are added, the guard must be updated. Consider extracting an `isAnyOverlayVisible` computed property in the future.

-## Why
-
-Two focus-related bugs in the video player cause crashes and broken UI states during D-pad navigation: (1) pressing UP/DOWN while in compact seek mode (after LEFT/RIGHT with hidden UI) crashes because Slider's `focusProperties` point to `FocusRequester`s that are not in the composition tree during compact mode, and (2) pressing UP/DOWN while a side sheet (episode selector, speed, resize) is open incorrectly triggers the hidden-UI shortcut handler, showing the full control overlay on top of the still-visible side sheet — creating a confusing double-overlay state.
-
-## What Changes
-
-- **Bug 1 fix**: Prevent UP/DOWN crash during compact seek mode by having the Slider handle UP/DOWN key events to exit compact mode gracefully, instead of relying on `focusProperties` that point to removed composables.
-- **Bug 2 fix**: Guard the hidden-UI D-pad shortcut handler in `VideoPlayerScreen` to not intercept keys when any side sheet (episode/speed/resize) is visible, allowing side sheets to handle their own focus navigation.
-
-## Capabilities
-
-### New Capabilities
-
-- `player-focus-dpad-safety`: Crash-free D-pad navigation during compact seek mode and correct side-sheet-aware key routing
-
-### Modified Capabilities
-
-- `player-focus-navigation`: Hidden-UI shortcut handler must skip UP/DOWN/CENTER when side sheets are visible, and Slider must safely handle UP/DOWN during compact seek mode instead of crashing via dangling focusProperties
-
-## Impact
-
-- `VideoPlayerScreen.kt`: outer `.onKeyEvent` handler (add side-sheet visibility guard)
-- `Slider.kt` or `VideoPlayerControl.kt`: handle UP/DOWN during compact mode (slider's key event or its `focusProperties`)
-- No API changes, no dependency changes, no breaking changes

-# Player Focus D-pad Safety
-
-## Purpose
-
-Crash-free and correct D-pad focus navigation for all video player UI states, including the compact seek overlay and side-sheet-open states.
-
-## ADDED Requirements
-
-### Requirement: UP/DOWN during compact seek exits to full UI without crash
-
-When the video player is in compact seek mode (overlay showing only slider + timestamp after LEFT/RIGHT with hidden UI), pressing UP or DOWN SHALL safely exit compact mode and show the full control UI, rather than crashing due to dangling focus targets.
-
-#### Scenario: UP during compact seek mode
-- **WHEN** user presses LEFT or RIGHT with hidden UI to enter compact seek mode
-- **AND** the slider has focus showing the compact overlay (slider + timestamp only)
-- **AND** user presses UP on D-pad
-- **THEN** the Slider SHALL consume the UP key event
-- **AND** the full control UI SHALL become visible (header + slider + playback controls)
-- **AND** the application SHALL NOT crash
-
-#### Scenario: DOWN during compact seek mode
-- **WHEN** the slider has focus in compact seek mode
-- **AND** user presses DOWN on D-pad
-- **THEN** the Slider SHALL consume the DOWN key event
-- **AND** the full control UI SHALL become visible
-- **AND** the application SHALL NOT crash
-
-#### Scenario: LEFT/RIGHT during compact seek mode continue seeking
-- **WHEN** the slider has focus in compact seek mode
-- **AND** user presses LEFT or RIGHT on D-pad
-- **THEN** the Slider SHALL seek by 10 seconds per press (existing behavior unchanged)
-
-### Requirement: D-pad keys pass through to side sheets without triggering control UI
-
-When a side sheet (episode selector, playback speed, or video resize) is visible, D-pad direction keys and the center/OK key SHALL be routed to the side sheet, NOT intercepted by the hidden-UI shortcut handler.
-
-#### Scenario: UP/DOWN with episode sheet open
-- **WHEN** the episode selector side sheet is open (`isEpisodeUiVisible = true`)
-- **AND** the control overlay is hidden (`isControlUiVisible = false`)
-- **AND** user presses UP or DOWN on D-pad
-- **THEN** the key event SHALL pass through to the episode side sheet
-- **AND** the control overlay SHALL NOT appear
-- **AND** the episode side sheet SHALL remain open
-
-#### Scenario: UP/DOWN with speed sheet open
-- **WHEN** the playback speed side sheet is open (`isSpeedUiVisible = true`)
-- **AND** the control overlay is hidden
-- **AND** user presses UP or DOWN on D-pad
-- **THEN** the key event SHALL pass through to the speed side sheet
-- **AND** the control overlay SHALL NOT appear
-
-#### Scenario: UP/DOWN with resize sheet open
-- **WHEN** the video resize side sheet is open (`isResizeUiVisible = true`)
-- **AND** the control overlay is hidden
-- **AND** user presses UP or DOWN on D-pad
-- **THEN** the key event SHALL pass through to the resize side sheet
-- **AND** the control overlay SHALL NOT appear
-
-#### Scenario: CENTER/OK with side sheet open
-- **WHEN** any side sheet is open
-- **AND** the control overlay is hidden
-- **AND** user presses CENTER or Spacebar on D-pad
-- **THEN** the key event SHALL pass through to the side sheet
-- **AND** playback SHALL NOT pause
-- **AND** the control overlay SHALL NOT appear
-
-#### Scenario: LEFT/RIGHT with side sheet open
-- **WHEN** any side sheet is open
-- **AND** the control overlay is hidden
-- **AND** user presses LEFT or RIGHT on D-pad
-- **THEN** the key event SHALL pass through
-- **AND** no timed seek SHALL occur
-- **AND** the compact seek overlay SHALL NOT appear

-# Player Focus Navigation (Delta)
-
-## MODIFIED Requirements
-
-### Requirement: Initial focus on control show
-
-When the player control overlay becomes visible via D-pad input or initial load, focus SHALL be placed on the appropriate control. When any side sheet (episode, speed, or resize) is visible, the hidden-UI shortcut handler SHALL NOT intercept D-pad keys — the keys SHALL pass through to the side sheet.
-
-#### Scenario: Default focus on initial player load
-- **WHEN** the player first opens
-- **AND** the control UI is visible
-- **THEN** focus is on the play/pause button
-
-#### Scenario: Left key with hidden UI
-- **WHEN** user presses LEFT on D-pad while controls are hidden
-- **AND** no side sheet is visible
-- **THEN** playback seeks backward 10 seconds
-- **AND** a compact overlay appears showing the progress slider and timestamp
-- **AND** the full control overlay (header, playback buttons) does NOT appear
-- **AND** focus is placed on the slider so subsequent LEFT presses continuously seek
-
-#### Scenario: Right key with hidden UI
-- **WHEN** user presses RIGHT on D-pad while controls are hidden
-- **AND** no side sheet is visible
-- **THEN** playback seeks forward 10 seconds
-- **AND** a compact overlay appears showing the progress slider and timestamp
-- **AND** the full control overlay (header, playback buttons) does NOT appear
-- **AND** focus is placed on the slider so subsequent RIGHT presses continuously seek
-
-#### Scenario: Continuous seek from hidden UI
-- **WHEN** user presses LEFT or RIGHT while controls are hidden
-- **AND** then continues pressing LEFT or RIGHT
-- **THEN** each subsequent press seeks by 10 seconds
-- **AND** the compact overlay remains visible
-- **AND** the slider thumb shows focus animation (grow + white border)
-
-#### Scenario: Controls shown via up key
-- **WHEN** user presses UP on D-pad while controls are hidden
-- **AND** no side sheet is visible
-- **THEN** the control overlay becomes visible
-- **AND** focus is placed on the Forward 85s button in the header row
-
-#### Scenario: Controls shown via down key
-- **WHEN** user presses DOWN on D-pad while controls are hidden
-- **AND** no side sheet is visible
-- **THEN** the control overlay becomes visible
-- **AND** focus is placed on the "选集" (episode) text button in the playback control row
-
-#### Scenario: Controls shown via OK/Center key
-- **WHEN** user presses OK/Center on D-pad while controls are hidden
-- **AND** the video is currently playing
-- **AND** no side sheet is visible
-- **THEN** playback pauses
-- **AND** the control overlay becomes visible
-- **AND** focus is placed on the play/pause button
-
-#### Scenario: UP/DOWN key during compact seek mode exits to full UI
-- **WHEN** the slider has focus in compact seek mode (after LEFT/RIGHT with hidden UI)
-- **AND** the compact overlay is showing (slider + timestamp only)
-- **AND** user presses UP or DOWN on D-pad
-- **THEN** the Slider SHALL consume the key event and exit compact mode
-- **AND** the full control UI SHALL become visible
-- **AND** the application SHALL NOT crash from dangling focus targets
-
-#### Scenario: Hidden-UI shortcuts suppressed when side sheet is open
-- **WHEN** any side sheet (episode, speed, resize) is visible
-- **AND** the control overlay is hidden
-- **AND** user presses any D-pad direction key or CENTER/Spacebar
-- **THEN** the hidden-UI shortcut handler SHALL NOT intercept the key
-- **AND** the key event SHALL pass through to the side sheet for its own navigation

-## Context
-
-The video player has a control overlay (`VideoPlayerControl`) with three visual rows:
-1. **Header row**: Back button, title, options (Forward 85s + MoreVert dropdown)
-2. **Slider row**: Timeline label + fullscreen toggle, then the progress slider
-3. **Playback control row**: Play/pause, next episode, danmaku toggle (left group); speed, resize, episode selection (right group)
-
-Currently there is no structured D-pad focus flow between these rows. The `defaultRemoteControlHandler` on the outer `VideoPlayer` handles basic show/hide and play/pause, but when controls are visible, focus navigation between rows is left to Compose's default spatial algorithm, which can produce wrong targets because row items have varying widths and horizontal positions.
-
-The custom `Slider` already has its own D-pad left/right handling for seeking, but always uses a single `color` parameter (currently set to `inversePrimary`) for the progress track and thumb, providing no visual distinction between focused and unfocused states.
-
-### Constraints
-- The `video-player` module is a separate Gradle module from `app` and cannot depend on `app`'s shared focus utilities (`DpadKeyHandler.kt`, `FocusHighlight.kt`)
-- The `Slider` component is in the `video-player` module
-- The slider must remain usable via touch (drag/tap) regardless of focus state
-- No external TV library dependency (consistent with existing focus architecture)
-
-## Goals / Non-Goals
-
-**Goals:**
-- Predictable vertical D-pad focus flow: header ↔ slider ↔ playback controls
-- Horizontal navigation within each row (left/right for buttons, seeking for slider)
-- Visual focus feedback on the slider via color change (primary when focused, dimmer when not)
-- Works with existing `defaultRemoteControlHandler` (no regression in remote control behavior)
-
-**Non-Goals:**
-- Rewriting the entire player controller UI structure
-- Changing the slider's existing D-pad seek step size
-- Touch/gesture behavior changes
-
-## Decisions
-
-### Decision 1: Back key hides UI first, exits on second press
-
-**Choice**: When the player control UI is visible, pressing Back hides the UI (calls `playerState.hideControlUi()`). When the UI is already hidden, Back exits the player normally via `onBackPress`.
-
-**Rationale**: This matches standard media player behavior on Android TV (YouTube, Netflix). Users open controls to check progress or adjust settings — a single Back should dismiss the overlay, not exit the player.
-
-**Implementation**: The `BackHandler` in `VideoPlayer` currently calls `onBackPress()` unconditionally. Change it to check `playerState.isControlUiVisible` — if visible, hide controls; otherwise, call `onBackPress`.
-
-### Decision 2: Direction key shortcuts — compact overlay with slider focus for LEFT/RIGHT continuous seek
-
-**Choice**: When controls are hidden and user presses LEFT/RIGHT, a **compact overlay** appears (only slider + timestamp visible; header and playback rows hidden by `isSeeking = true`) AND **focus is placed on the slider**. Because the slider now has focus, subsequent LEFT/RIGHT presses are handled by the slider's own `onKeyEvent` — enabling **continuous seek** via repeated presses or hold. The compact overlay auto-hides via the normal 6-second auto-hide timer (not a custom 1.5s coroutine).
-
-Hidden UI shortcuts:
-- **LEFT** → 10-second seek back, show compact overlay, focus slider
-- **RIGHT** → 10-second seek forward, show compact overlay, focus slider
-- **UP** → show full control UI, focus Forward 85s button
-- **DOWN** → show full control UI, focus "选集" button
-- **OK/Center** → pause + show full control UI, focus play/pause
-
-Full UI + slider focus (10s seek):
-- **LEFT** → slider's own `onKeyEvent` seeks 10s back (continuous)
-- **RIGHT** → slider's own `onKeyEvent` seeks 10s forward (continuous)
-
-**Rationale**: The previous design used a 1.5s auto-hide coroutine and did not focus the slider, so subsequent LEFT/RIGHT presses had no handler (the outer Box's `onKeyEvent` returns false when `isControlUiVisible` is true, and the slider had no focus). By focusing the slider on the first press, continuous seek works naturally — the slider's own `onKeyEvent` handles every subsequent press. Reusing the normal 6s auto-hide timer (reset by `onUserInteraction()` on every key via `onPreviewKeyEvent`) means the overlay stays visible while the user keeps pressing, and disappears 6s after the last press. `isSeeking = true` keeps the overlay compact (hides header + playback rows); it is reset to `false` in `hideControlUi()` so the next `showControlUi()` renders the full UI.
-
-**Implementation**: `onTimedSeek(skipMs)` is a new method on `VideoPlayerState` (implemented in `VideoPlayerStateImpl`):
-1. If UI not visible, `showControlUi()` — starts the auto-hide timer (resets `isSeeking=false` + `hideAfterMs=6s`)
-2. `isSeeking.value = true` — overrides `showControlUi`'s reset, hides header + playback rows (compact overlay)
-3. `hideAfterMs = seekHideAfterMs` (1500ms) — overrides `showControlUi`'s 6s with a shorter 1.5s timer
-4. `controlUiLastInteractionMs = 0` — reset timer so 1.5s counts from this seek
-5. Compute new position, update `videoProgress`, call `player.seekTo(newPos)`
-
-In `VideoPlayerScreen.kt`, the outer Box's `onKeyEvent` calls `playerState.onTimedSeek(±10000)` then sets `pendingFocusTarget = FocusTarget.SLIDER` for the deferred focus queue.
-
-**Critical: `isSeeking` lifecycle** — `isSeeking` is NOT reset in `hideControlUi()` or `onSeeked()`. It stays true during fade-out so the compact overlay fades out directly (no full UI flash). It is reset to `false` only in `showControlUi()`, so the next time the UI is shown (tap or UP/DOWN/OK), it starts in full UI mode.
-
-**Short seek timer**: A new `hideAfterMs` variable (default 6s, set to 1.5s during seeking) controls the auto-hide delay. The polling loop in `showControlUi()` checks `controlUiLastInteractionMs >= hideAfterMs`. `onUserInteraction()` (called on every D-pad key via `onPreviewKeyEvent`) resets `controlUiLastInteractionMs = 0`, so continuous D-pad pressing keeps resetting the 1.5s timer. The overlay hides 1.5s after the last key press.
-
-**Touch drag**: `onSeeking()` reorders to call `showControlUi()` before setting `isSeeking=true` (so `showControlUi`'s `isSeeking=false` reset doesn't clobber it). `onSeeked()` no longer resets `isSeeking` — it sets `hideAfterMs = 1.5s` and resets the timer, so the compact overlay hides 1.5s after drag release without flashing to full UI.
-
-### Decision 3: Default focus on initial load
-
-**Choice**: After `LaunchedEffect(url)` calls `showControlUi()`, use `LaunchedEffect(Unit)` with `runCatching` to request focus on the play/pause button.
-
-**Rationale**: `showControlUi()` is called on initial playback start but no FocusRequester is ever invoked programmatically. The user sees controls but D-pad is dead until they press a direction key. Defaulting to play/pause gives an immediate, natural starting point.
-
-### Decision 4: Fullscreen button hidden on TV
-
-**Choice**: The `TimelineControl` composable SHALL use `LocalContext.current.packageManager.hasSystemFeature(PackageManager.FEATURE_LEANBACK)` to detect TV devices. On TV, the fullscreen toggle button is not rendered at all.
-
-**Rationale**: The fullscreen toggle is a phone-only feature — it switches between landscape fullscreen and portrait 16:9. On TV, both orientation changes are skipped (`isAndroidTV` / `isWideScreen` guards return early), and the screen is already ~16:9. Hiding it entirely removes an unnecessary dead control from the UI and eliminates it from the focus flow automatically.
-
-### Decision 5: Explicit focusProperties routing + focusable anchor
-
-**Choice**: Two mechanisms work together:
-
-1. **Outer Box** gets `.focusable()` + `onKeyEvent` handler (`handlePlayerKeys`). When the control UI is hidden, this Box holds focus — providing a Compose focus node so key events are dispatched. `handlePlayerKeys` intercepts LEFT/RIGHT (KeyDown, 10s seek + compact overlay + `pendingFocusTarget = SLIDER` to focus the slider) and UP/DOWN/OK (KeyUp, show controls + focus target). After the first LEFT/RIGHT, the slider has focus and handles subsequent presses itself.
-
-2. **Row-level `focusProperties`** on the back button, slider, and play/pause button explicitly declare direction targets using `FocusRequester` references. This bypasses Compose's spatial search entirely — which cannot work because the outer `focusable` Box at `fillMaxSize` always appears "closest" to every candidate.
-
-| Component | `focusProperties` |
-|---|---|
-| Back button (IconButton) | `down = sliderFocusRequester` |
-| Slider (Box) | `up = backFocusRequester`; `down = playPauseFocusRequester` |
-| PlayPause button (AdaptiveIconButton) | `up = sliderFocusRequester` |
-
-**Rationale**: After attempting spatial search, `moveFocus()`, `requestFocus()` safety nets, and `canFocus = false`, the root issue is that the outer Box MUST be focusable (for hidden-UI key dispatch) but MUST NOT participate in spatial search (it's `fillMaxSize` and always wins). `focusProperties` with explicit FocusRequester targets is the only mechanism that satisfies both constraints. The Compose focus skill advises: "Use this sparingly. Too many hard-coded links create stale focus graphs when layouts change. Prefer natural focus order unless the design requires a specific jump or trap." This is that case — the outer Box is an unavoidable trap that requires explicit routing.
-
-**Implementation**:
-- `VideoPlayerScreen.kt`: Outer Box gets `.focusable() + onKeyEvent(handlePlayerKeys)`
-- `VideoPlayerControl.kt`: Back `IconButton` gets `Modifier.focusProperties { down = sliderFocusRequester }`; `Slider` Box gets `Modifier.focusProperties { up = backFocusRequester; down = playPauseFocusRequester }`; `PlayPauseButton` gets `Modifier.focusProperties { up = sliderFocusRequester }`
-- New FocusRequester: `backFocusRequester`
-- `Slider.kt`: expose `focusProperties` via a `focusPropertiesModifier` parameter or apply it in `BottomControlBar`
-
-### Decision 6: Slider focus feedback — thumb-only, no track color change
-
-**Choice**: The slider signals D-pad focus through thumb animations only: thumb grows from 15dp to 20dp and gains a **3dp white border**. The track color (play progress, buffered, unplayed) remains unchanged on focus. The `focusedColor` parameter exists for callers who explicitly want focused track differentiation but defaults to `primary` (same as `color`).
-
-| Parameter | Default | Meaning |
-|---|---|---|
-| `color` | `MaterialTheme.colorScheme.primary` | Play progress + thumb (unfocused) |
-| `focusedColor` | `MaterialTheme.colorScheme.primary` | Play progress + thumb (focused) — same as unfocused by default |
-| `trackColor` | `Color.LightGray.copy(alpha = 0.38f)` | Unplayed track (unchanged) |
-| `secondTrackColor` | `Color.LightGray.copy(alpha = 0.78f)` | Buffered track (unchanged) |
-
-**Rationale**: The default `color` is the app's brand `primary` — changing it to white would alter the phone UX for the sake of TV focus, which is the wrong trade-off. The thumb's size increase (15→20dp) and white border (0→3dp) already provide clear, unambiguous focus feedback without touching track colors at all. This keeps phone and TV experiences unified: the slider looks the same on both form factors, with TV adding only the thumb animation overlay.
-
-**Critical fix — `onFocusChanged` order**: The thumb animation was not working because `.onFocusChanged { ... }` was placed **after** `.focusable()` in the modifier chain. In Compose, `onFocusChanged` must be placed **before** `.focusable()` to observe the focusable node's own focus state. When placed after, it observes a child node and `isFocused` never becomes true. See Decision 11 for details.
-
-**Slider D-pad seek step**: Changed to 10 seconds (`10000f / durationMs`). 10s is the standard TV seek step (YouTube TV, Netflix). This unifies the hidden-UI quick seek and the focused-slider seek to the same step size, so the first press and subsequent presses feel consistent.
-
-### Decision 7: No shared utility dependency for video-player module
-
-**Choice**: Use inline `onKeyEvent` for row boundaries and inline focus state tracking in `VideoPlayerControl.kt`, consistent with the module's existing self-contained approach (`AdaptiveIconButton`, `AdaptiveTextButton`).
-
-**Rationale**: The `video-player` module already has its own focus patterns using `MutableInteractionSource` and `onFocusChanged`. Adding a dependency on `app` module or creating a shared utility module would be architectural overhead for a single consumer. The module's self-contained focus helpers (`AdaptiveIconButton`, `AdaptiveTextButton`) already work well — we just extend the pattern to row navigation.
-
-### Decision 8: Focus routing target selection
-
-**Choice**: When pressing DOWN from the header row, move focus to the slider. When pressing DOWN from the slider, move focus to the first button in the playback control row (play/pause). UP reverses the flow.
-
-**Rationale**: This follows the visual layout: header is topmost, slider is middle, playback controls are bottom. The slider is the most important control for seeking, so DOWN from header goes there first. UP from slider goes to back button in header (the most prominent header control).
-
-### Decision 9: Speed/resize side sheets receive auto-focus and Back support
-
-**Choice**: Add `FocusRequester` + `LaunchedEffect(Unit)` to the first item in `SpeedSideSheet` and `ResizeSideSheet`. Add `BackHandler` to both side sheets to close on Back key press.
-
-**Rationale**: Currently `showSpeedUi()` calls `hideControlUi()`, which removes the entire `VideoPlayerControl` composable tree from composition — including whichever button had focus (e.g., the "倍速" button). When the side sheet appears via `AnimatedVisibility`, no element requests focus, so the D-pad has no target. This is why side sheet items appear "unfocusable."
-
-The `AdaptiveTextButton` composable already has full inverse-color focus handling (`collectIsFocusedAsState` + `collectIsPressedAsState`), so once focus enters the side sheet, highlighting works automatically. No color changes needed in `AdaptiveTextButton`.
-
-**Implementation**:
-- First `AdaptiveTextButton` in each side sheet gets `Modifier.focusRequester(focusRequester)`
-- `LaunchedEffect(Unit) { runCatching { focusRequester.requestFocus() } }` places focus on the first item
-- `BackHandler { onDismissRequest() }` closes the sheet on Back key
-- On dismiss, `VideoPlayerControl` reappears; existing slider focus behavior resumes
-
-### Decision 10: Auto-hide timer resets on any D-pad key event
-
-**Choice**: Add a `Modifier.onPreviewKeyEvent` on the inner `VideoPlayer` Box that calls `playerState.onUserInteraction()` — which resets `controlUiLastInteractionMs` to 0 — and returns `false` (does not consume the event). Add `onUserInteraction()` to the `VideoPlayerState` interface.
-
-**Rationale**: The current auto-hide timer (`controlUiLastInteractionMs`) only resets on button clicks (`play()`, `pause()`, `onSeeking()`, `onClickSlider()`, etc.) and `showControlUi()`. D-pad navigation keys (UP/DOWN/LEFT/RIGHT/OK) do NOT reset the timer. This means:
-- When browsing DropdownMenu items with D-pad, the timer keeps counting.
-- When navigating between control buttons, the timer keeps counting.
-- The UI can disappear mid-navigation.
-
-Using `onPreviewKeyEvent` at the `VideoPlayer` Box level (priority before any child) and returning `false` ensures:
-- Every D-pad key resets the timer.
-- No keys are consumed — child composables (slider seeking, dropdown menu, etc.) continue to work normally.
-
-**Implementation**:
-- `VideoPlayerState` interface gets `fun onUserInteraction()` (default no-op for backwards compatibility)
-- `VideoPlayerStateImpl` implements it as `controlUiLastInteractionMs = 0`
-- Inner `VideoPlayer` Box gets `.onPreviewKeyEvent { playerState.onUserInteraction(); false }`
-
-### Decision 11: Fix `onFocusChanged` modifier order in Slider.kt
-
-**Choice**: Move `.onFocusChanged { isFocused = it.isFocused }` to **before** `.focusable()` in the Slider's modifier chain.
-
-**Rationale**: This was the root cause of Bug 1 (thumb never animating in full UI). In Compose, modifier order matters for focus: `onFocusChanged` observes the focus state of the node created by the **next** modifier in the chain. When `onFocusChanged` is placed after `focusable()`, it observes a child of the focusable node, and `it.isFocused` never becomes true. The correct order is:
-
-```kotlin
-modifier
-    .focusRequester(focusRequester)
-    .onFocusChanged { isFocused = it.isFocused }  // BEFORE focusable
-    .focusable()
-    .onKeyEvent { ... }
-```
-
-This is documented in the Compose focus API: "onFocusChanged should be placed before focusable/focusGroup modifiers to observe their focus state."
-
-### Decision 12: Unify hidden-UI seek with slider focus (continuous seek)
-
-**Choice**: When the user presses LEFT/RIGHT with the UI hidden, the compact overlay appears AND the slider receives focus (`pendingFocusTarget = FocusTarget.SLIDER`). Subsequent LEFT/RIGHT presses are then handled by the slider's own `onKeyEvent` — enabling continuous seek via repeated presses or hold.
-
-**Rationale**: The previous design did not focus the slider on the first LEFT/RIGHT press. After `showControlUi()` set `isControlUiVisible = true`, the outer Box's `onKeyEvent` returned false (because `if (isControlUiVisible) return false`), and the slider had no focus — so subsequent LEFT/RIGHT presses went nowhere. The user observed "无UI时按左右键有放大加白边但是依然无法长按或多次按键来持续快退快进" — the thumb appeared to animate (because `isSeeking = true` drove `isActive`), but continuous seek did not work. By focusing the slider on the first press, the slider's own `onKeyEvent` takes over and continuous seek works naturally.
-
-**Implementation**:
-- Add `FocusTarget.SLIDER` to the enum
-- In the outer Box's `onKeyEvent`, LEFT/RIGHT KeyDown: after `onTimedSeek(...)`, set `pendingFocusTarget = FocusTarget.SLIDER`
-- The existing `LaunchedEffect(pendingFocusTarget)` deferred focus queue handles the `sliderFocusRequester.requestFocus()` call after `AnimatedVisibility` composes
-
-### Decision 13: Slider D-pad seek uses `onClick` instead of `onValueChange` + `onValueChangeFinished`
-
-**Choice**: The slider's `onKeyEvent` for LEFT/RIGHT calls `onClick(progress)` (which maps to `state.onClickSlider` — updates `videoProgress` + seeks the player directly) instead of `onValueChange(progress)` + `onValueChangeFinished()` (which map to `state.onSeeking` + `state.onSeeked` — sets `isSeeking = true` then `false`).
-
-**Rationale**: `onSeeking` sets `isSeeking = true` and `onSeeked` sets `isSeeking = false`. If the slider's `onKeyEvent` used this path, each D-pad seek press would flip `isSeeking` true→false, causing the compact overlay (which relies on `isSeeking = true` to hide header + playback rows) to flash back to full UI on each press. By using `onClick` (which does NOT toggle `isSeeking`), the compact overlay stays compact during continuous seek. The thumb animation is driven by `isFocused` (Decision 11 fix), not `isSeeking`, so it remains visible throughout.
-
-**Implementation** in `Slider.kt`:
-```kotlin
-.onKeyEvent { event ->
-    if (event.type == KeyEventType.KeyDown) {
-        val stepFraction = if (durationMs > 0) 10000f / durationMs else 0.02f
-        when (event.key) {
-            Key.DirectionRight -> { onClick((value + stepFraction).coerceIn(0f, 1f)); true }
-            Key.DirectionLeft -> { onClick((value - stepFraction).coerceIn(0f, 1f)); true }
-            else -> false
-        }
-    } else false
-}
-```
-
-### Decision 14: Unify seek step to 10 seconds
-
-**Choice**: Both the hidden-UI quick seek (`onTimedSeek`) and the focused-slider D-pad seek use **10 seconds** (`10000ms` / `10000f / durationMs`).
-
-**Rationale**: The previous design used 5s for hidden-UI and 30s for focused-slider. Now that hidden-UI seek focuses the slider (Decision 12), the first press (10s via `onTimedSeek`) and subsequent presses (via slider's `onKeyEvent`) must use the same step — otherwise the first press jumps 5s and subsequent presses jump 30s, which feels jarring. 10s is the standard TV seek step (YouTube TV, Netflix, Android TV system media controls). The `ExoPlayer.Builder` config in `rememberVideoPlayerState` also sets `setSeekForwardIncrementMs(15 * 1000)` / `setSeekBackIncrementMs(15 * 1000)` — these should be updated to 10s as well for consistency, though they are only used by `control.forward()` / `control.rewind()` which are not currently called by D-pad handlers.
-
-**Implementation**:
-- `Slider.kt`: `stepFraction = 10000f / durationMs`
-- `VideoPlayerScreen.kt` `onTimedSeek`: `skipMs = ±10000`
-- `VideoPlayerSate.kt` `rememberVideoPlayerState`: `setSeekForwardIncrementMs(10 * 1000)`, `setSeekBackIncrementMs(10 * 1000)`
-
-## Risks / Trade-offs
-
-- **Risk**: `onKeyEvent` at row level may interfere with the slider's own left/right key handling.
-  - **Mitigation**: Use `onKeyEvent` (not `onPreviewKeyEvent`) so child composables consume keys first. Only intercept Up/Down which the slider doesn't handle anyway.
-
-- **Risk**: The player control's `AnimatedVisibility` enter/exit may cause `FocusRequester` timing issues (similar to the reverse list crash on detail page).
-  - **Mitigation**: Use `runCatching` for `requestFocus()` calls and avoid storing `FocusRequester` across composable lifecycles.
-
-- **Trade-off**: The `focusedColor` addition makes the Slider API slightly larger, but it's a single optional parameter with a sensible default.

-## Why
-
-The video player control overlay currently has no structured D-pad focus navigation between its rows (header, slider, playback controls). When the user presses up/down, focus jumps unpredictably. Additionally, the progress slider always uses the `primary` color regardless of focus state, making it hard to tell when the slider is focused — a problem for TV users who rely on clear focus indicators.
-
-## What Changes
-
-- **Player control focus routing**: Add D-pad vertical navigation boundaries between the three control rows (header, slider, playback), so up/down moves predictably between rows while left/right navigates within each row.
-- **Slider focus-aware color**: The `Slider` component will indicate D-pad focus via the thumb only — the thumb grows larger (15→20dp) and gains a 3dp white border when focused. The progress track and buffered track colors remain unchanged (defaulting to `primary`), consistent with both phone and TV usage. The `focusedColor` parameter is available for callers that want focused track color differentiation, but defaults to `primary` (no track change). A critical fix moves `.onFocusChanged` before `.focusable()` in the modifier chain so the focus callback actually fires.
-- **Direction key shortcuts when UI hidden**: When the control overlay is hidden: pressing LEFT/RIGHT seeks 10 seconds, shows a compact overlay (slider + timestamp only), AND focuses the slider so subsequent LEFT/RIGHT presses continuously seek via the slider's own key handler; pressing UP shows UI and focuses the Forward 85s button; pressing DOWN shows UI and focuses the "选集" button; pressing OK/Center pauses playback, shows UI, and focuses the play/pause button.
-- **Unified 10-second seek step**: Both the hidden-UI quick seek and the focused-slider D-pad seek use 10 seconds, so the first press and subsequent continuous presses feel consistent.
-- **Default focus on load**: When the player first opens with the control UI visible, focus defaults to the play/pause button so D-pad navigation is immediately available.
-- **Back key hides UI**: When the control overlay is visible, pressing Back hides the UI instead of exiting the player. Pressing Back again (with UI hidden) exits the player.
-- **Speed/resize side sheet focus**: When the speed or resize side sheet opens, focus is automatically placed on the first selectable item. Pressing Back closes the side sheet and returns focus to the main control UI. The currently selected item uses bold text in addition to `primary` color for clear visual distinction.
-- **Auto-hide timer respects D-pad**: The player UI auto-hide timer resets on ANY D-pad key event (including navigation keys), not just button clicks. This prevents the UI from disappearing while the user is browsing with the remote.
-
-## Capabilities
-
-### New Capabilities
-- `player-focus-navigation`: Structured D-pad focus flow between the three control rows in the video player overlay — header (back + options) → slider → playback controls (play/pause, next, danmaku, speed, resize, episode). Up/down moves between rows; left/right navigates within each row.
-
-### Modified Capabilities
-- `tv-focus-inverse-color`: The Slider component SHALL use `primary` color only when focused. When unfocused, it uses a dimmer color (the `color` parameter), consistent with the inverse-color pattern used by buttons.
-
-## Impact
-
-- `video-player/src/.../component/Slider.kt`: Fix `onFocusChanged` modifier order (before `.focusable()`); change D-pad seek step to 10s; use `onClick` instead of `onValueChange`+`onValueChangeFinished` in `onKeyEvent`; `focusedColor` parameter retained (defaults to `primary`, no track color change on focus)
-- `video-player/src/.../VideoPlayerControl.kt`: Add `onKeyEvent` boundaries; expose FocusRequesters; hide fullscreen button on TV; Slider call site simplified (no need for `progressLineColor`)
-- `video-player/src/.../VideoPlayer.kt`: Back key hides UI first; `onPreviewKeyEvent` resets auto-hide timer
-- `video-player/src/.../VideoPlayerSate.kt`: `hideControlUi()` resets `isSeeking = false`; `rememberVideoPlayerState` seek increments changed to 10s
-- `app/.../videoplayer/VideoPlayerScreen.kt`: `defaultRemoteControlHandler` — LEFT/RIGHT hidden=10s seek + compact overlay + focus slider (continuous seek), UP/DOWN/OK show UI+focus targets; `LaunchedEffect` for default play/pause focus on load; Speed/Resize side sheet FocusRequester + BackHandler

-## Context
-
-The `video-player` module's `VideoPlayerControl` composable renders a control overlay on top of video content. Currently it uses a uniform `Color.Black.copy(0.2f)` background across the entire overlay. All buttons use `Color.Transparent` as their container color in the normal (unfocused) state, with `Color.White` or `Color.LightGray` for icons and text. This creates a visibility problem against bright/white video content.
-
-The reference implementation [open-ani/animeko](https://github.com/open-ani/animeko) uses `Brush.verticalGradient` in `VideoScaffold.kt` to create dark-to-transparent gradients at the top and bottom edges of the player, providing strong contrast where controls are while keeping the center of the video unobstructed.
-
-The change is scoped to a single file: `VideoPlayerControl.kt` in the `video-player` module.
-
-## Goals / Non-Goals
-
-**Goals:**
-- Replace the uniform overlay background with vertical gradient overlays at the top and bottom
-- Ensure white/LightGray icons and text remain clearly visible against any video content (including pure white frames)
-- Preserve the existing `background` parameter API on `VideoPlayerControl` for callers that override it
-- Keep the center of the video unobstructed and clear
-
-**Non-Goals:**
-- Adding shadows (`Modifier.shadow()`) to individual icons or text — gradients provide sufficient contrast
-- Adding per-button background circles (`Color.Black.copy(0.25f)` on `AdaptiveIconButton`) — not needed with gradient approach
-- Modifying the `app` module's `VideoPlayerScreen.kt` — all changes stay in the library module
-- Changing TV/D-pad focus behavior (focus navigation, inverse colors, focus traversal specs are unaffected)
-
-## Decisions
-
-### Decision 1: Use two `Box` overlays with `Brush.verticalGradient` instead of modifying the uniform `background` parameter
-
-**Rationale**: Animeko's approach uses separate gradient `Box` elements that sit *under* the control UI but *over* the video. This is cleaner than trying to express a gradient through the existing `background: Color` parameter. The existing parameter continues to work for callers that pass it, but the default rendering no longer relies on it.
-
-**Alternatives considered**:
-- *Increase uniform background alpha from 0.2f to 0.5f*: Simpler, but makes the entire overlay darker and looks amateurish.
-- *Add `Modifier.shadow()` to individual buttons/text*: Shadow on circular IconButtons renders as a square shadow (Android Compose limitation). Text shadows help but don't fully solve the problem.
-- *Add semi-transparent circular backgrounds to each `AdaptiveIconButton`*: Works but looks "heavy" — many dark circles scattered across the overlay.
-
-### Decision 2: Use `matchParentSize()` for gradient boxes + `Column` for controls
-
-**Rationale**: Two `Box` composables sized to `matchParentSize()` sit behind the control `Column`. The top box covers the full width/height but only the top ~35% has visible gradient. The bottom box similarly covers only the bottom ~35%. The `Column` with `Spacer(Modifier.weight(1f))` keeps controls at their edge positions without overlap.
-
-```kotlin
-Box(modifier.fillMaxSize()) {
-    // Gradient layers (behind controls)
-    Box(Modifier.matchParentSize().background(topGradient))
-    Box(Modifier.matchParentSize().background(bottomGradient))
-    // Control layers (on top)
-    Column {
-        ControlHeader(...)
-        Spacer(Modifier.weight(1f))
-        BottomControlBar(...)
-    }
-}
-```
-
-### Decision 3: Gradient parameters
-
-Following animeko's lead:
-- **Top gradient**: `0f → Color.Black.copy(0.55f)`, `0.35f → Color.Transparent`
-- **Bottom gradient**: `0f → Color.Transparent`, `0.65f → Color.Transparent`, `1f → Color.Black.copy(0.55f)`
-
-The 0.55f alpha is stronger than the current 0.2f but only applies at the edges. The middle 30% of the screen (where controls don't live) stays fully transparent.
-
-### Decision 4: Keep `AdaptiveIconButton` unchanged
-
-With gradient overlays providing sufficient contrast, `AdaptiveIconButton`'s `Color.Transparent` default container color is fine. TV focus highlighting (`containerColor = primary` when focused) still works on top of the gradient.
-
-## Risks / Trade-offs
-
-- **Gradient colors tuned for dark mode only**: The player currently always uses a dark overlay. If light mode player support is added later, gradients would need inversion. Mitigation: not in scope; the entire player UI assumes dark backgrounds.
-- **Gradient rendering on low-end devices**: `Brush.verticalGradient` on a full-screen `Box` may cause overdraw. Mitigation: gradients are simple 2-3 stop linear gradients; Compose handles these efficiently.
-- **Edge case — very short videos in portrait mode**: In portrait (non-fullscreen), the gradient may cover proportionally more of the video since the video area is shorter. Mitigation: this is acceptable — portrait mode already has limited video real estate, and controls still need contrast.

-## Why
-
-Player control buttons, icons, and text currently render without any background — they appear as pure white or light gray directly on top of video content. When the underlying video frame is bright or white, all controls become nearly invisible. The current uniform `Color.Black.copy(0.2f)` overlay is too faint to provide adequate contrast.
-
-## What Changes
-
-- Replace the uniform semi-transparent black background (`Color.Black.copy(0.2f)`) on the control overlay with **vertical gradient overlays** — a dark-to-transparent gradient at the top and a transparent-to-dark gradient at the bottom
-- Increase effective contrast in the header (title, back button) and playback control areas while keeping the center of the video fully visible
-- Reference implementation: [open-ani/animeko](https://github.com/open-ani/animeko) `VideoScaffold.kt`
-- No API changes; existing `background` parameter on `VideoPlayerControl` remains functional for callers that override it
-
-## Capabilities
-
-### New Capabilities
-- `player-gradient-overlay`: Vertical gradient backgrounds for the video player control overlay's header and footer regions, providing adequate contrast for white icons/text against any video content
-
-### Modified Capabilities
-<!-- None — existing specs (player-focus-navigation, tv-focus-inverse-color, tv-focus-traversal) are unaffected -->
-
-## Impact
-
-- **Module**: `video-player` (`VideoPlayerControl.kt`) — single file change
-- **Breaking**: None — the `background` composable parameter remains available; only its default rendering changes
-- **TV/D-pad**: Focus highlight (primary color on focused buttons) continues to work; focus navigation specs unaffected

-## ADDED Requirements
-
-### Requirement: Player overlay uses vertical gradient backgrounds
-
-The video player control overlay SHALL render vertical gradient backgrounds at the top and bottom edges instead of a uniform semi-transparent background, providing stronger contrast for white icons and text against bright video content while keeping the center of the video fully visible.
-
-#### Scenario: Top gradient provides contrast for header controls
-
-- **WHEN** the player control overlay is visible
-- **THEN** the top edge of the overlay SHALL display a vertical gradient from `Color.Black.copy(0.55f)` at the top to `Color.Transparent` at approximately 35% from the top
-- **AND** the back button, title text, and subtitle text in the header SHALL be clearly visible against any underlying video content
-
-#### Scenario: Bottom gradient provides contrast for playback controls
-
-- **WHEN** the player control overlay is visible
-- **THEN** the bottom edge of the overlay SHALL display a vertical gradient from `Color.Transparent` at approximately 65% from the top to `Color.Black.copy(0.55f)` at the bottom
-- **AND** the playback buttons, timestamp text, slider, and text buttons SHALL be clearly visible against any underlying video content
-
-#### Scenario: Center of video remains unobstructed
-
-- **WHEN** the player control overlay is visible
-- **THEN** the middle portion of the overlay (approximately 35% to 65% from the top) SHALL be fully transparent
-- **AND** the video content in this region SHALL not be dimmed or obscured by the overlay
-
-#### Scenario: Gradient overlay on pure white video frame
-
-- **WHEN** the underlying video content is pure white (#FFFFFF)
-- **AND** the player control overlay is visible
-- **THEN** all control icons and text SHALL be readable with sufficient contrast
-- **AND** no control element SHALL blend into the white background
-
-#### Scenario: Gradient overlay on very dark video frame
-
-- **WHEN** the underlying video content is very dark or black
-- **AND** the player control overlay is visible
-- **THEN** the gradient edges SHALL blend seamlessly with the dark video content
-- **AND** white icons and text SHALL remain clearly visible without appearing overly bright
-
-### Requirement: Existing background parameter remains functional
-
-The `background` parameter on `VideoPlayerControl` SHALL remain in the function signature without breaking changes, ensuring backward compatibility for callers that pass a custom background color.
-
-#### Scenario: Caller passes custom background color
-
-- **WHEN** a caller passes a custom `background` parameter to `VideoPlayerControl`
-- **THEN** the composable SHALL honor the custom background and not render the default gradient overlays
-
-#### Scenario: Caller does not pass background parameter
-
-- **WHEN** a caller invokes `VideoPlayerControl` without overriding the `background` parameter
-- **THEN** the composable SHALL render the default vertical gradient overlays (top and bottom)

-## Requirements
-
-### Requirement: Slider thumb renders without visual artifacts
-
-The slider thumb SHALL render as a clean, solid circle without any visible edge artifacts, regardless of the background behind it.
-
-#### Scenario: Thumb against gradient overlay background
-
-- **WHEN** the player control overlay is visible with its gradient background
-- **AND** the slider thumb is displayed
-- **THEN** the thumb SHALL NOT show any visible sub-pixel white/grey ring around its edge
-- **AND** the thumb SHALL appear as a clean solid circle with smooth edges
-
-#### Scenario: Thumb against transparent background
-
-- **WHEN** the slider is displayed without any background overlay (e.g., compact seek mode)
-- **THEN** the thumb SHALL NOT show any visible ring artifact
-- **AND** the thumb SHALL appear as a clean solid circle
-
-#### Scenario: Thumb rendering is independent of focus state
-
-- **WHEN** the slider thumb is NOT focused and NOT in seeking mode
-- **THEN** the thumb SHALL NOT have any visible border or edge artifact
-- **AND** the thumb SHALL be a solid circle rendered at its base size (15dp)
-
-#### Scenario: Thumb border only appears when active
-
-- **WHEN** the slider is focused OR in seeking mode (isActive = true)
-- **THEN** the thumb SHALL display a 2dp white circular border
-- **AND** when isActive becomes false, the border modifier SHALL be removed entirely from the chain (not set to 0dp)
-- **AND** the border SHALL disappear completely with no residual edge artifact
-
-## Implementation
-
-### Root cause
-
-Two issues combined to produce the visible ring:
-
-1. **Chip anti-aliasing**: `.clip(CircleShape)` followed by `.background(color)` renders the thumb as a color-filled rectangle, then clips it to a circle using an alpha mask. At the circle's edge, GPU anti-aliasing produces semi-transparent pixels. When the background behind the thumb is itself semi-transparent (gradient overlay), these edge pixels blend to produce a visible lighter ring.
-
-2. **zero-width border side effect**: `.border(0.dp, Color.White, CircleShape)` still inserts a `BorderStroke` into the modifier chain, which Skia processes even at zero width — producing a ~1px edge artifact on some rendering paths.
-
-### Fix
-
-Two changes to the thumb modifier chain:
-
-```kotlin
-// Before
-.clip(CircleShape)
-.size(thumbSize)
-.border(if (isActive) 3.dp else 0.dp, Color.White, CircleShape)
-.background(color)
-
-// After
-.size(thumbSize)
-.then(if (isActive) Modifier.border(2.dp, Color.White, CircleShape) else Modifier)
-.background(color, CircleShape)
-```
-
-1. **Remove `.clip(CircleShape)`**: use `.background(color, CircleShape)` instead — Skia rasterizes the background directly as a circle, eliminating the clip alpha-mask pass and its anti-aliasing artifact.
-2. **Conditional border via `.then()`**: skip the border modifier entirely when not active, rather than passing `0.dp`. Also reduced active border from 3dp to 2dp.

-## Context
-
-The video player and long-press context menus have three TV interaction bugs. The most critical is that on tablet devices (Switch OLED, Pixel Tablet emulator), the Back key requires two presses to dismiss player UI because Compose's `OnBackPressedDispatcher` on non-TV devices does not forward `Key.Back` events when focusable elements are in the tree. The other two are missing focus visuals on long-press menus, and an asymmetric D-pad OK button behavior.
-
-### Key finding from investigation
-
-On the tablet emulator (API 35), logcat confirms that `onPreviewKeyEvent` and root `onKeyEvent` both receive the first `Key.Back` press, but `BackHandler` does NOT fire until the second press. This is a Compose platform difference between TV (where `BackHandler` fires immediately) and tablet (where the focus system intercepts the first Back press before the dispatcher).
-
-## Goals / Non-Goals
-
-**Goals:**
-- Single Back press hides player UI on all device types (TV, tablet, phone)
-- Long-press menus in download and favorites screens show focus highlight
-- D-pad OK/Center toggles play/pause when control UI is hidden, mirroring touch double-tap
-
-**Non-Goals:**
-- Changing `hideSystemBars()` behavior (verified unrelated)
-- Refactoring the entire focus or BackHandler system
-- Adding new utility or abstraction files
-
-## Decisions
-
-### Decision 1: Intercept Back key in root `onKeyEvent` instead of fixing `BackHandler`
-
-**Rationale:** The `BackHandler` (via `OnBackPressedDispatcher`) path is unreliable on tablet Compose. The root `onKeyEvent` already has a hidden-UI shortcut handler that checks UI visibility state. Adding Back key handling there is a natural fit — same location, same state checks.
-
-**Priority when multiple UI layers are visible:**
-
-```
-1. Side sheet open?  → close side sheet (speed > resize > episode)
-2. Control UI open?  → hide control UI
-3. Nothing open?     → pass through (→ BackHandler → exit player)
-```
-
-**Alternatives considered:**
-- *Override `dispatchKeyEvent` in Activity*: Too invasive, affects all screens, harder to scope to player only.
-- *Use `onPreviewKeyEvent` instead*: Would consume before focus system, but harder to coordinate with children.
-
-### Decision 2: Use existing `rememberIsFocused()` from `FocusHighlight.kt`
-
-**Rationale:** The `tv-focus-inverse-color` spec already mandates `rememberIsFocused()` as the single source of truth. The download `PopupMenuListItem` and favorites inline menu simply never adopted it. No new abstraction needed.
-
-### Decision 3: Toggle play/pause in OK handler, matching touch double-tap
-
-**Rationale:** The touch double-tap handler in `VideoPlayer.kt:154-159` already implements symmetric toggle. The D-pad OK handler mirrors this: `if playing → pause + show UI`, `if paused → play only (no UI)` — same as touch double-tap which doesn't show controls.
-
-### Decision 4: Key.Menu triggers context menus, not D-pad long-press
-
-**Rationale:** D-pad long-press is unintuitive on remotes/gamepads and behaves inconsistently across TV vs tablet Compose (FLAG_LONG_PRESS fires on Sony TV but not Switch). The `Key.Menu` keycode (82) is the standard Android mechanism for context/overflow actions. Touch long-press via `combinedClickable.onLongClick` is preserved for touchscreen users. Both paths open the same `DropdownMenu`.
-
-### Decision 5: Delete mode for favorites and download detail
-
-**Rationale:** D-pad users need a discoverable way to delete without relying on popup menus.
-A top-bar `OutlinedButton` toggles delete mode. Cards show a centered trash icon
-overlay (visual indicator only). Clicking/D-pad OK on the card body triggers delete.
-Pressing Back in delete mode exits delete mode (does not navigate away).
-Pattern inspired by FongMi/TV (`holder.binding.delete.setVisibility`).
-
-**Behavior:**
-- Top-bar shows `OutlinedButton` with `rememberIsFocused()` + `buttonColors` for proper
-  inverse-color focus highlighting.
-- In delete mode: button shows inverse-color + "Cancel"; each card overlays a centered
-  `Icons.Rounded.Delete` icon at 48dp, semi-transparent.
-- Click/D-pad OK on card body → delete. The trash icon is NOT a separate click target.
-- Back key in delete mode → exits delete mode.
-- Animation: trash icon fades in/out with `AnimatedVisibility`.
-
-### Decision 6: Player starts without control UI
-
-**Rationale:** Showing the control overlay on every launch adds unnecessary visual clutter
-and an extra interaction step. Removing `showControlUi()` in `LaunchedEffect(url)` lets
-playback start with a clean fullscreen view. The control UI still appears on any
-D-pad/touch interaction.
-
-### Decision 7: App exit confirmation dialog
-
-When pressing Back on the home/main screen, show an `AlertDialog` with "确认退出?"
-and two `OutlinedButton` choices ("Cancel" / "OK"). Buttons use `OutlinedButton` +
-`buttonColors` + `rememberIsFocused()` for proper inverse-color focus.
-
-## Risks / Trade-offs
-
-- **Back key consumed in `onKeyEvent` returns `true`**: This means child composables won't see the Back key event. But since the only action needed when UI is visible is "hide UI and move on", this is acceptable. Children that need to handle Back (like text fields) aren't present in the player overlay.
-- **Order-of-operations for Back key intercept**: The intercept logic must check visibility states in the same order as `BackHandler` registration (innermost first). Side sheet checks must come before control UI checks.

-## Why
-
-Multiple TV/handheld interaction bugs degrade the experience. The Back key requires two presses on tablet devices. Long-press context menus (downloads, favorites) lack focus highlighting and don't work reliably with D-pad. The D-pad OK button can't resume playback hidden UI. Context menu actions (delete) have no accessible D-pad alternative. The player control overlay appears on every launch, adding friction.
-
-## What Changes
-
-- **Context menus via Key.Menu**: Keep touch long-press, but use `Key.Menu` (remote) instead of unreliable D-pad long-press for opening popup menus on TV/handheld.
-- **PopupMenu inverse color**: `DropdownMenuItem` in download/favorites menus display `primary`/`onPrimary` focus highlighting.
-- **Player Back key**: Intercept `Key.Back` in root `onKeyEvent` to immediately hide UI on all devices.
-- **D-pad OK toggle**: Hidden UI + OK → playing → pause + show UI; paused → play only.
-- **Delete mode**: Favorites and download detail screens get a "delete" button (top-right). Activating it enters delete mode — clicking a card/row deletes it. Touch long-press + Menu key still available as shortcuts.
-- **Download detail "anime detail" button**: Navigate from download detail back to the anime detail page.
-- **Player starts without control UI**: Remove the `showControlUi()` call on initial load — controls appear only on user interaction (D-pad, touch).
-
-## Capabilities
-
-### New Capabilities
-
-- `player-back-key-intercept`: Intercept Back key at root `onKeyEvent` to dismiss player UI immediately on all device types.
-- `delete-mode`: Favorites and download detail screens support a toggleable delete mode accessible via a top-right button.

-### Modified Capabilities
-
-- `tv-focus-inverse-color`: `DropdownMenuItem` in download and favorites menus SHALL display inverse-color focus.
-- `player-focus-navigation`: D-pad OK/Center when UI hidden SHALL toggle play/pause. Player starts playback without showing the control overlay.

-## Context
-
-Animius uses Material 3 theming with three color sources: custom seed color (Catppuccin palette), dynamic color (Material You wallpaper-based), and hardcoded fallback. The `AnimeTheme` composable in `Theme.kt` selects the color scheme based on user preferences, then applies it to `MaterialTheme`. Surface/background colors are generated automatically by M3's tonal palette system, producing tinted grays that some users find undesirable on AMOLED screens.
-
-Current preference flow: `SettingsPreferences` (singleton with `MutableStateFlow` + `SharedPreferences`) → `AnimeTheme` collects state → selects `ColorScheme` → passes to `MaterialTheme`.
-
-## Goals / Non-Goals
-
-**Goals:**
-- Add a toggle that overrides the `background` and `surface` color roles with a flat color (white for light, #121212 for dark)
-- Keep all other M3 color roles (primary, secondary, surfaceVariant, etc.) untouched
-- Maintain full compatibility with dynamic color and custom seed color
-- Use existing `SwitchPref` composable and preference infrastructure
-
-**Non-Goals:**
-- Override `surfaceVariant`, `surfaceContainer`, or other surface-level container colors (future enhancement if requested)
-- Implement AMOLED pure black (#000000) — using #121212 per Material Design dark theme standard
-- Add per-source or per-screen background customization
-
-## Decisions
-
-### 1. Override at `ColorScheme` level via `.copy(background = ..., surface = ...)`
-
-**Decision**: After the color scheme is determined (dynamic or custom seed), apply `scheme.copy(background = ..., surface = ...)` if `pureBackground` is true.
-
-**Rationale**: Clean, composable approach. The override happens at the same level as the scheme selection, keeping the logic centralized. Uses `.let {}` to chain the override after the `when` block.
-
-**Alternatives considered**:
-- Override in a custom `LocalBackgroundColor` composition local → over-engineered for a single color role
-- Modify `getSchemeFromSeed()` to accept a background override → mixes concerns
-
-### 2. Dark background = `#121212` (not pure `#000000`)
-
-**Decision**: Use Material Design's standard dark surface color `0xFF121212`.
-
-**Rationale**: Pure black causes black smearing on OLED panels during scrolling. `#121212` is the established Material Design dark background and is widely recognized as "dark mode" while avoiding visual artifacts.
-
-### 3. No interaction with dynamic color
-
-**Decision**: `pureBackground` only overrides `background`, regardless of whether dynamic color is active. Dynamic color continues to control primary/secondary/tertiary and all other roles.
-
-**Rationale**: Users may want both — Material You accent colors from wallpaper AND a flat background. Forcing mutual exclusion would reduce flexibility.
-
-### 4. Preference stored as Boolean with default `false`
-
-**Decision**: Single boolean toggle, off by default. Named `pureBackground` in code, "黑白背景" in UI.
-
-**Rationale**: Simple on/off matches the feature scope. Default `false` preserves existing behavior for all users.
-
-## Risks / Trade-offs
-
-- **Only `background` and `surface` are overridden** → Cards, chips, and other container elements using `surfaceVariant`, `surfaceContainer*` will still have M3 tinted colors. This may look inconsistent to some users. Mitigation: can be extended to override more surface roles later if requested.
-- **#121212 vs #000000 debate** → Some AMOLED enthusiasts want pure black. Mitigation: #121212 avoids black smearing; can add a "pure AMOLED" option later.
-- **No `onBackground` override** → If the background changes to white/black, the text color (`onBackground`) might not have optimal contrast against M3-generated onBackground. In practice, M3's onBackground is already near-black/near-white, so this should be fine.

-## Why
-
-Many AMOLED users prefer pure black/dark backgrounds for battery savings and visual cleanliness. The current Material 3 theme always applies tinted surfaces (e.g. purple-tinted grays) which some users find distracting. Adding a "黑白背景" toggle lets users opt into flat black/white backgrounds while keeping M3 accent colors intact.
-
-## What Changes
-
-- Add a new preference `pureBackground` (Boolean, default `false`)
-- When enabled:
-  - Light theme: `background` and `surface` colors → `#FFFFFF` (white)
-  - Dark theme: `background` and `surface` colors → `#121212` (Material standard dark)
-- Only the `background` and `surface` color roles are overridden — `surfaceVariant`, accent colors, and all other M3 color roles remain unchanged
-- Does NOT affect dynamic color (Material You) — dynamic color continues to apply to accent colors; only `background` is overridden when this toggle is on
-- Add a toggle switch labeled "黑白背景" in the Appearance settings screen
-
-## Capabilities
-
-### New Capabilities
-- `pure-background`: A toggle in Appearance settings that overrides the M3 background and surface colors with flat black (dark) or white (light), independent of dynamic color and custom theme color.
-
-### Modified Capabilities
-
-## Impact
-
-- **Files modified**:
-  - `util/Preferences.kt` — new `KEY_PURE_BACKGROUND` constant
-  - `util/SettingsPreferences.kt` — new `pureBackground` StateFlow + `changePureBackground()` method
-  - `presentation/theme/Theme.kt` — both `AnimeTheme` overloads accept and apply `pureBackground` override (background + surface)
-  - `presentation/screen/settings/AppearanceScreen.kt` — new `SwitchPref` toggle for the setting
-  - `res/values/strings.xml` — new string resources for label and description
-- **No breaking changes**: default is `false`, existing behavior unchanged
-- **No new dependencies**: uses existing Material Icons `Contrast` icon

-## ADDED Requirements
-
-### Requirement: Pure background preference
-The system SHALL provide a boolean preference `pureBackground` (default `false`) that controls whether the theme background color is overridden with a flat color.
-
-#### Scenario: Default state
-- **WHEN** user has never toggled the pure background setting
-- **THEN** `pureBackground` SHALL be `false` and the M3 generated background color SHALL be used
-
-#### Scenario: Preference persists across app restarts
-- **WHEN** user enables pure background and restarts the app
-- **THEN** pure background SHALL remain enabled
-
-### Requirement: Background and surface color override
-When `pureBackground` is `true`, the system SHALL override the `background` and `surface` color roles of the active `ColorScheme`.
-
-#### Scenario: Light theme with pure background enabled
-- **WHEN** theme mode is Light (or System + device is light) AND `pureBackground` is `true`
-- **THEN** `background` and `surface` colors SHALL be `#FFFFFF` (white)
-
-#### Scenario: Dark theme with pure background enabled
-- **WHEN** theme mode is Dark (or System + device is dark) AND `pureBackground` is `true`
-- **THEN** `background` and `surface` colors SHALL be `#121212`
-
-#### Scenario: Other color roles unchanged
-- **WHEN** `pureBackground` is `true`
-- **THEN** `primary`, `secondary`, `tertiary`, `surfaceVariant`, and all other non-background/surface color roles SHALL remain unchanged from the active color scheme
-
-### Requirement: Dynamic color compatibility
-The pure background setting SHALL NOT interfere with dynamic color (Material You). When both are active, dynamic color determines accent colors while the flat background overrides only the `background` role.
-
-#### Scenario: Dynamic color + pure background
-- **WHEN** `dynamicColor` is `true` AND `pureBackground` is `true` on Android 12+
-- **THEN** primary/secondary/tertiary colors SHALL come from the wallpaper-derived dynamic scheme AND background/surface SHALL be the flat override color
-
-### Requirement: Appearance settings toggle
-The system SHALL display a toggle switch labeled "黑白背景" in the Appearance settings screen with a description explaining the behavior.
-
-#### Scenario: Toggle visibility
-- **WHEN** user opens Appearance settings
-- **THEN** a "黑白背景" toggle SHALL be visible below the dynamic image color toggle
-
-#### Scenario: Toggle interaction
-- **WHEN** user taps the "黑白背景" toggle
-- **THEN** `pureBackground` preference SHALL toggle and the theme background SHALL update immediately without restarting the app

-## Context
-
-The project has two focus-tracking utilities in `FocusHighlight.kt`:
-
-| Function | Returns | Touch behavior |
-|----------|---------|---------------|
-| `rememberIsFocused()` | `(isFocused, Modifier)` | No inversion (correct) |
-| `rememberInteractionFocus()` | `(isFocused \|\| isPressed, InteractionSource)` | Inverts color on press (incorrect) |
-
-`rememberInteractionFocus` was created to "prevent visual flash during click" — the idea being that if `containerColor` jumps from `transparent` to `primary` on focus change, pressing first smooths the transition. But this solves a non-problem: M3 buttons already animate color transitions, and `IconButton` has no such flash. The real cost is that touch interactions look wrong — buttons turn primary color on every press instead of showing a ripple.
-
-The main app's `IconButton` usage (HomeScreen, DetailScreen, Settings, etc.) exclusively uses `rememberIsFocused`. Only `rememberInteractionFocus` call sites and the video-player module's inline implementations have this issue.
-
-## Goals / Non-Goals
-
-**Goals:**
-- Eliminate primary color inversion on touch for ALL buttons
-- Single focus-tracking utility: `rememberIsFocused`
-- Delete `rememberInteractionFocus` (no callers remain)
-- Fix `AdaptiveIconButton` and `AdaptiveTextButton` to match
-
-**Non-Goals:**
-- No change to ripple behavior, focus traversal, or D-pad key handling
-- No new utility functions (we already have the right one)
-- No change to `VideoPlayerScreen.kt` failure page button behavior — those M3 `OutlinedButton` call sites already correctly pass `interactionSource`; they just need their `isPressed` logic removed
-
-## Decisions
-
-### Decision 1: Delete `rememberInteractionFocus`, don't deprecate
-
-**Chosen:** Direct deletion after all call sites migrated.
-
-**Rationale:** The function has 12 call sites. After migration, zero callers remain. Deprecation adds noise with no benefit. The function is internal, not a public API.
-
-### Decision 2: Remove `interactionSource` param from M3 buttons
-
-**Chosen:** For `Button`/`OutlinedButton`/`TextButton` call sites, remove the custom `interactionSource`. Use `rememberIsFocused` modifier for focus state.
-
-**Rationale:** M3 buttons create their own default `MutableInteractionSource` when none is passed. The custom source was only needed because `rememberInteractionFocus` exposed `collectIsPressedAsState()` on it. Without press tracking, there's no reason to pass a custom source. The `rememberIsFocused` modifier handles focus tracking independently.
-
-**Alternative considered:** Keep passing `interactionSource` but stop reading `isPressed` from it. Rejected — adds unnecessary complexity; M3's default source works identically for ripple.
-
-### Decision 3: `AdaptiveIconButton` uses `rememberIsFocused` modifier, not inline state
-
-**Chosen:** Add a `focusModifier` parameter to `AdaptiveIconButton`, wired to `rememberIsFocused` at each call site.
-
-**Rationale:** `AdaptiveIconButton` currently tracks focus and press inline. Replacing with `rememberIsFocused` unifies with the rest of the project. The modifier approach (`.onFocusChanged`) is simpler than `MutableInteractionSource` + `collectIsFocusedAsState()`.
-
-**Alternative considered:** Keep `interactionSource` but stop reading `isPressed`. Rejected — adds `MutableInteractionSource` creation + `collectIsFocusedAsState` boilerplate when `Modifier.onFocusChanged` is sufficient.
-
-## Risks / Trade-offs
-
-- **[Risk] M3 Button color jump on focus change without press smoothing** → Mitigation: M3 buttons use `animateColorAsState` internally for smooth transitions. The "flash" concern was theoretical; no actual jank observed in practice with `rememberIsFocused`.
-- **[Trade-off] ~14 files changed for a behavior fix** → The change is mechanical (find-and-replace) across most files. Risk of merge conflicts is low since each file only touches one utility function call.

-## Why
-
-`rememberInteractionFocus()` returns `isActive = isFocused || isPressed`, causing touch interactions to trigger primary color inversion on all M3 buttons (IconButton, TextButton, OutlinedButton, Button). This conflicts with Material3's intended touch behavior (ripple only, no color change). The function is used across 12 call sites in 8 files, while the rest of the project already correctly uses `rememberIsFocused()` (focus-only, ~50 call sites). This creates inconsistent UX between player controls, dialog buttons, and main app buttons.
-
-## What Changes
-
-- Delete `rememberInteractionFocus()` from `FocusHighlight.kt`
-- Replace all 12 `rememberInteractionFocus` calls with `rememberIsFocused`
-- Fix `AdaptiveIconButton` in video-player: remove inline `isPressed` tracking, use `rememberIsFocused`
-- Fix `AdaptiveTextButton` in video-player: remove inline `isPressed` tracking, use `rememberIsFocused`
-- For `Button`/`OutlinedButton`/`TextButton` call sites: remove custom `interactionSource` param (M3 uses its own default source for ripple; focus comes from `rememberIsFocused` modifier instead)
-- Clean up unused `collectIsPressedAsState` imports
-
-## Capabilities
-
-### New Capabilities
-
-- `player-button-press-highlight`: All focusable components use focus-only highlight — touch preserves Material3 default ripple, D-pad focus triggers primary color inversion. Single utility function (`rememberIsFocused`) for the entire project.
-
-### Modified Capabilities
-
-None — this is a new capability establishing a project-wide convention.
-
-## Impact
-
-- **`FocusHighlight.kt`**: delete 1 function (~12 lines)
-- **`VideoPlayerControl.kt`**: `AdaptiveIconButton` + `AdaptiveTextButton` — remove `isPressed`, use `rememberIsFocused` (~15 lines changed)
-- **7 app files**: replace `rememberInteractionFocus` → `rememberIsFocused`, remove `interactionSource` param from M3 buttons (~12 call sites, mostly mechanical find-and-replace)
-- **Imports**: remove `collectIsPressedAsState` where it becomes unused
-- **No API or dependency changes**

-# Player Back Key Intercept
-
-## Purpose
-
-Ensure the Back key immediately dismisses player UI (control overlay and side sheets) on all device types by intercepting Back at the root `onKeyEvent` level, bypassing platform-specific `OnBackPressedDispatcher` behavior differences between TV and tablet Compose implementations.
-
-## Requirements
-
-### Requirement: Back key immediately hides player UI on all device types
-When the player control overlay or any side sheet (speed, resize, episode) is visible, pressing the Back key SHALL immediately hide the visible UI component in a single press, regardless of device type (TV, tablet, phone). The Back key SHALL be intercepted at the root `onKeyEvent` level to bypass platform-specific `OnBackPressedDispatcher` behavior differences between TV and tablet Compose implementations.
-
-#### Scenario: Back key hides control UI on tablet
-- **WHEN** the player control overlay is visible on a tablet device
-- **AND** user presses Back on D-pad, remote, or keyboard
-- **THEN** the control overlay hides immediately (single press)
-- **AND** focus is not lost before the UI disappears
-
-#### Scenario: Back key closes side sheet on tablet
-- **WHEN** a side sheet (speed, resize, or episode) is visible on a tablet device
-- **AND** user presses Back on D-pad, remote, or keyboard
-- **THEN** the side sheet closes immediately (single press)
-- **AND** focus is not lost before the UI disappears
-
-#### Scenario: Back key hides control UI on TV
-- **WHEN** the player control overlay is visible on a TV device
-- **AND** user presses Back on D-pad or remote
-- **THEN** the control overlay hides immediately (single press)
-- **AND** existing TV behavior is preserved (no regression)
-
-#### Scenario: Back key closes side sheet on TV
-- **WHEN** a side sheet (speed, resize, or episode) is visible on a TV device
-- **AND** user presses Back on D-pad or remote
-- **THEN** the side sheet closes immediately (single press)
-- **AND** existing TV behavior is preserved (no regression)
-
-### Requirement: Back key interception coexists with BackHandler for exit
-The root `onKeyEvent` intercept for Back key SHALL only consume the event when player UI or side sheets are visible. When all UI is hidden, the Back key SHALL pass through to the existing `BackHandler` which triggers player exit.
-
-#### Scenario: Back key exits player when all UI is hidden
-- **WHEN** all player UI (control overlay, side sheets) is hidden
-- **AND** user presses Back
-- **THEN** the root `onKeyEvent` does NOT consume the Back event
-- **AND** the existing `BackHandler` triggers player exit
-
-#### Scenario: Back key only hides UI when multiple layers are visible
-- **WHEN** both control overlay and a side sheet are visible (side sheet was opened from control overlay)
-- **AND** user presses Back
-- **THEN** the side sheet closes (highest priority)
-- **AND** the control overlay remains hidden (does not reappear)

-## Requirements
-
-### Requirement: All focusable components use focus-only highlight
-
-All buttons and interactive components in the app SHALL only highlight (primary color inversion) when focused via D-pad or controller. Touch/press interactions SHALL use the default Material3 ripple without triggering primary color inversion.
-
-#### Scenario: Touch preserves Material3 ripple
-
-- **WHEN** any focusable button (IconButton, TextButton, OutlinedButton, Button) is touched
-- **THEN** the button SHALL show the default Material3 ripple on its current background
-- **AND** the button SHALL NOT change its container color or content color on press
-
-#### Scenario: D-pad focus triggers color inversion
-
-- **WHEN** any focusable button receives D-pad focus (via TV remote or controller)
-- **THEN** the button background SHALL turn `MaterialTheme.colorScheme.primary`
-- **AND** the icon/text color SHALL invert to `MaterialTheme.colorScheme.onPrimary`
-
-#### Scenario: Consistent behavior across all screens
-
-- **WHEN** any button is used in the app (player overlay, dialogs, error pages, settings, detail page, home screen, etc.)
-- **THEN** its highlight behavior SHALL be identical: focus drives color, touch drives ripple only
-- **AND** there SHALL be only one focus-tracking utility function used throughout the project
-
-## Implementation
-
-### Root cause
-
-`rememberInteractionFocus()` returns `isActive = isFocused || isPressed`, causing ALL component types (IconButton, TextButton, OutlinedButton, Button) to invert colors on touch. This is incorrect — touch should only show Material3 ripple.
-
-### Fix
-
-1. **Replace all `rememberInteractionFocus` calls with `rememberIsFocused`** across 8 files (12 call sites)
-2. **Delete `rememberInteractionFocus`** from `FocusHighlight.kt`
-3. **Fix `AdaptiveIconButton`** in video-player: use `rememberIsFocused` instead of inline `isPressed` tracking
-4. **Fix `AdaptiveTextButton`** in video-player: use `rememberIsFocused` instead of inline `isPressed` tracking
-5. **For `Button`/`OutlinedButton`/`TextButton`**: remove custom `interactionSource` parameter — M3 uses its own default source for ripple; focus state comes from `rememberIsFocused` modifier
-
-### Files affected
-
-| File | Change |
-|------|--------|
-| `FocusHighlight.kt` | Delete `rememberInteractionFocus()` |
-| `VideoPlayerControl.kt` | `AdaptiveIconButton` + `AdaptiveTextButton`: use `rememberIsFocused` |

-# Player Focus D-pad Safety
-
-## Purpose
-
-Crash-free and correct D-pad focus navigation for all video player UI states, including the compact seek overlay and side-sheet-open states.
-
-## Requirements
-
-### Requirement: UP/DOWN during compact seek exits to full UI without crash
-
-When the video player is in compact seek mode (overlay showing only slider + timestamp after LEFT/RIGHT with hidden UI), pressing UP or DOWN SHALL safely exit compact mode and show the full control UI, rather than crashing due to dangling focus targets.
-
-#### Scenario: UP during compact seek mode
-- **WHEN** user presses LEFT or RIGHT with hidden UI to enter compact seek mode
-- **AND** the slider has focus showing the compact overlay (slider + timestamp only)
-- **AND** user presses UP on D-pad
-- **THEN** the Slider SHALL consume the UP key event
-- **AND** the full control UI SHALL become visible (header + slider + playback controls)
-- **AND** the application SHALL NOT crash
-
-#### Scenario: DOWN during compact seek mode
-- **WHEN** the slider has focus in compact seek mode
-- **AND** user presses DOWN on D-pad
-- **THEN** the Slider SHALL consume the DOWN key event
-- **AND** the full control UI SHALL become visible
-- **AND** the application SHALL NOT crash
-
-#### Scenario: LEFT/RIGHT during compact seek mode continue seeking
-- **WHEN** the slider has focus in compact seek mode
-- **AND** user presses LEFT or RIGHT on D-pad
-- **THEN** the Slider SHALL seek by 10 seconds per press (existing behavior unchanged)
-
-### Requirement: D-pad keys pass through to side sheets without triggering control UI
-
-When a side sheet (episode selector, playback speed, or video resize) is visible, D-pad direction keys and the center/OK key SHALL be routed to the side sheet, NOT intercepted by the hidden-UI shortcut handler.
-
-#### Scenario: UP/DOWN with episode sheet open
-- **WHEN** the episode selector side sheet is open (`isEpisodeUiVisible = true`)
-- **AND** the control overlay is hidden (`isControlUiVisible = false`)
-- **AND** user presses UP or DOWN on D-pad
-- **THEN** the key event SHALL pass through to the episode side sheet
-- **AND** the control overlay SHALL NOT appear
-- **AND** the episode side sheet SHALL remain open
-
-#### Scenario: UP/DOWN with speed sheet open
-- **WHEN** the playback speed side sheet is open (`isSpeedUiVisible = true`)
-- **AND** the control overlay is hidden
-- **AND** user presses UP or DOWN on D-pad
-- **THEN** the key event SHALL pass through to the speed side sheet
-- **AND** the control overlay SHALL NOT appear
-
-#### Scenario: UP/DOWN with resize sheet open
-- **WHEN** the video resize side sheet is open (`isResizeUiVisible = true`)
-- **AND** the control overlay is hidden
-- **AND** user presses UP or DOWN on D-pad
-- **THEN** the key event SHALL pass through to the resize side sheet
-- **AND** the control overlay SHALL NOT appear
-
-#### Scenario: CENTER/OK with side sheet open
-- **WHEN** any side sheet is open
-- **AND** the control overlay is hidden
-- **AND** user presses CENTER or Spacebar on D-pad
-- **THEN** the key event SHALL pass through to the side sheet
-- **AND** playback SHALL NOT pause
-- **AND** the control overlay SHALL NOT appear
-
-#### Scenario: LEFT/RIGHT with side sheet open
-- **WHEN** any side sheet is open
-- **AND** the control overlay is hidden
-- **AND** user presses LEFT or RIGHT on D-pad
-- **THEN** the key event SHALL pass through
-- **AND** no timed seek SHALL occur
-- **AND** the compact seek overlay SHALL NOT appear

-# Player Focus Navigation
-
-## Purpose
-
-Structured D-pad focus navigation for the video player control overlay, enabling predictable focus flow between header, slider, and playback control rows on TV/remote devices. Also covers direction key shortcuts when the control UI is hidden.
-
-## Requirements
-### Requirement: Vertical focus flows between player control rows
-Interactive elements in the video player control overlay SHALL transfer focus in visual row order (header → slider → playback controls) when the user presses up/down on D-pad, regardless of horizontal position differences between elements in adjacent rows.
-
-#### Scenario: Down from header row to slider
-- **WHEN** D-pad focus is on any focusable element in the header row (back button, forward button, or more options button)
-- **THEN** pressing DOWN moves focus to the slider
-
-#### Scenario: Down from slider to playback controls
-- **WHEN** D-pad focus is on the slider
-- **THEN** pressing DOWN moves focus to the play/pause button in the playback control row
-
-#### Scenario: Up from slider to header (TV)
-- **WHEN** D-pad focus is on the slider on a TV device (fullscreen button hidden)
-- **THEN** pressing UP moves focus to the back button in the header row
-
-#### Scenario: Up from slider to fullscreen button (non-TV)
-- **WHEN** D-pad focus is on the slider on a non-TV device (fullscreen button visible)
-- **THEN** pressing UP moves focus to the fullscreen button in the timeline row
-- **AND** default spatial algorithm handles this naturally (fullscreen button sits directly above slider's right side)
-
-#### Scenario: Up from playback controls to slider
-- **WHEN** D-pad focus is on any button in the playback control row
-- **THEN** pressing UP moves focus to the slider
-
-#### Scenario: Horizontal navigation within playback control row
-- **WHEN** D-pad focus is on a button in the playback control row
-- **THEN** pressing LEFT or RIGHT moves focus between buttons within the same row (standard spatial navigation)
-
-### Requirement: Slider D-pad seeking at 10-second step
-When the full control UI is visible and the slider has D-pad focus, LEFT/RIGHT SHALL seek by 10 seconds. The slider's `onKeyEvent` uses `onClick` (not `onValueChange` + `onValueChangeFinished`) so that `isSeeking` is not toggled and the compact overlay stays compact during continuous seek.
-
-#### Scenario: Left on focused slider seeks 10s back
-- **WHEN** D-pad focus is on the slider
-- **AND** the full control UI is visible
-- **THEN** pressing LEFT seeks backward by 10 seconds
-
-#### Scenario: Right on focused slider seeks 10s forward
-- **WHEN** D-pad focus is on the slider
-- **AND** the full control UI is visible
-- **THEN** pressing RIGHT seeks forward by 10 seconds
-
-#### Scenario: Continuous seek via repeated presses
-- **WHEN** D-pad focus is on the slider
-- **AND** the user presses LEFT or RIGHT multiple times in succession
-- **THEN** each press seeks by 10 seconds
-- **AND** the compact overlay remains visible (does not flash to full UI)
-
-#### Scenario: Slider thumb animates on focus
-- **WHEN** D-pad focus enters the slider
-- **THEN** the thumb grows from 15dp to 20dp with animation
-- **AND** a 3dp white border appears around the thumb
-- **AND** the `onFocusChanged` modifier is placed before `.focusable()` so the focus callback fires
-
-### Requirement: Initial focus on control show
-When the player control overlay becomes visible via D-pad input or initial load, focus SHALL be placed on the appropriate control. When any side sheet (episode, speed, or resize) is visible, the hidden-UI shortcut handler SHALL NOT intercept D-pad keys — the keys SHALL pass through to the side sheet.
-
-#### Scenario: Default focus on initial player load
-- **WHEN** the player first opens
-- **AND** the control UI is visible
-- **THEN** focus is on the play/pause button
-
-#### Scenario: Left key with hidden UI
-- **WHEN** user presses LEFT on D-pad while controls are hidden
-- **AND** no side sheet is visible
-- **THEN** playback seeks backward 10 seconds
-- **AND** a compact overlay appears showing the progress slider and timestamp
-- **AND** the full control overlay (header, playback buttons) does NOT appear
-- **AND** focus is placed on the slider so subsequent LEFT presses continuously seek
-
-#### Scenario: Right key with hidden UI
-- **WHEN** user presses RIGHT on D-pad while controls are hidden
-- **AND** no side sheet is visible
-- **THEN** playback seeks forward 10 seconds
-- **AND** a compact overlay appears showing the progress slider and timestamp
-- **AND** the full control overlay (header, playback buttons) does NOT appear
-- **AND** focus is placed on the slider so subsequent RIGHT presses continuously seek
-
-#### Scenario: Continuous seek from hidden UI
-- **WHEN** user presses LEFT or RIGHT while controls are hidden
-- **AND** then continues pressing LEFT or RIGHT
-- **THEN** each subsequent press seeks by 10 seconds
-- **AND** the compact overlay remains visible
-- **AND** the slider thumb shows focus animation (grow + white border)
-
-#### Scenario: Controls shown via up key
-- **WHEN** user presses UP on D-pad while controls are hidden
-- **AND** no side sheet is visible
-- **THEN** the control overlay becomes visible
-- **AND** focus is placed on the Forward 85s button in the header row
-
-#### Scenario: Controls shown via down key
-- **WHEN** user presses DOWN on D-pad while controls are hidden
-- **AND** no side sheet is visible
-- **THEN** the control overlay becomes visible
-- **AND** focus is placed on the "选集" (episode) text button in the playback control row
-
-#### Scenario: Controls shown via OK/Center key
-- **WHEN** user presses OK/Center on D-pad while controls are hidden
-- **AND** the video is currently playing
-- **AND** no side sheet is visible
-- **THEN** playback pauses
-- **AND** the control overlay becomes visible
-- **AND** focus is placed on the play/pause button
-
-#### Scenario: OK/Center resumes while paused with hidden UI
-- **WHEN** user presses OK/Center on D-pad while controls are hidden
-- **AND** the video is currently paused
-- **AND** no side sheet is visible
-- **THEN** playback resumes
-- **AND** the control overlay becomes visible
-- **AND** focus is placed on the play/pause button
-
-#### Scenario: UP/DOWN key during compact seek mode exits to full UI
-- **WHEN** the slider has focus in compact seek mode (after LEFT/RIGHT with hidden UI)
-- **AND** the compact overlay is showing (slider + timestamp only)
-- **AND** user presses UP or DOWN on D-pad
-- **THEN** the Slider SHALL consume the key event and exit compact mode
-- **AND** the full control UI SHALL become visible
-- **AND** the application SHALL NOT crash from dangling focus targets
-
-#### Scenario: Hidden-UI shortcuts suppressed when side sheet is open
-- **WHEN** any side sheet (episode, speed, resize) is visible
-- **AND** the control overlay is hidden
-- **AND** user presses any D-pad direction key or CENTER/Spacebar
-- **THEN** the hidden-UI shortcut handler SHALL NOT intercept the key
-- **AND** the key event SHALL pass through to the side sheet for its own navigation
-
-### Requirement: Back key hides player control UI
-When the player control overlay is visible, pressing the Back key SHALL hide the overlay instead of exiting the player.
-
-#### Scenario: Back key with UI visible
-- **WHEN** the player control overlay is visible
-- **AND** user presses Back on D-pad or remote
-- **THEN** the control overlay hides
-- **AND** the player does NOT exit
-
-#### Scenario: Back key with UI hidden
-- **WHEN** the player control overlay is hidden
-- **AND** user presses Back on D-pad or remote
-- **THEN** the player exits (standard back navigation)
-
-### Requirement: Fullscreen button hidden on TV
-The fullscreen toggle button in the `TimelineControl` row SHALL NOT be rendered on TV devices (Android TV / Leanback).
-
-#### Scenario: TimelineControl on TV
-- **WHEN** the player control overlay is rendered on a TV device (`FEATURE_LEANBACK`)
-- **THEN** the fullscreen toggle button is not visible
-- **AND** the timestamp text occupies its natural position
-
-### Requirement: Side sheets receive initial focus
-When the speed or resize side sheet opens, focus SHALL be automatically placed on the first selectable item so D-pad users can navigate immediately.
-
-#### Scenario: Speed side sheet opens
-- **WHEN** user activates the speed button ("倍速") with OK key
-- **THEN** the speed side sheet appears
-- **AND** focus is on the first speed option (e.g., "2.0X")
-
-#### Scenario: Resize side sheet opens
-- **WHEN** user activates the resize button ("适应") with OK key
-- **THEN** the resize side sheet appears
-- **AND** focus is on the first resize option (e.g., "适应")
-
-#### Scenario: Back key closes side sheet
-- **WHEN** a side sheet (speed or resize) is visible
-- **AND** user presses Back
-- **THEN** the side sheet closes
-- **AND** focus returns to the main control UI
-
-### Requirement: Auto-hide timer resets on D-pad input
-Any D-pad key event (up, down, left, right, center, back) SHALL reset the player UI auto-hide timer so the UI remains visible while the user is actively navigating with a remote.
-
-#### Scenario: D-pad navigation keeps UI alive
-- **WHEN** the player control UI is visible
-- **AND** user presses any D-pad direction key
-- **THEN** the auto-hide timer resets
-- **AND** the UI does NOT disappear during active navigation
-
-#### Scenario: Browsing dropdown menu keeps UI alive
-- **WHEN** the MoreVert dropdown menu is open
-- **AND** user presses UP or DOWN to browse menu items
-- **THEN** the auto-hide timer resets
-- **AND** the UI and dropdown menu remain visible

-### Requirement: Focus state includes press state
-For components using Pattern A (`interactionSource`), the active focus visual SHALL include the pressed state to prevent visual flash during click.
-
-#### Scenario: Button pressed while focused
-- **WHEN** user presses (clicks) a focused button
-- **THEN** the button SHALL retain the inverse-color appearance (not revert to default) until the press action completes
-
-### Requirement: Touch interaction unaffected
-Focus inverse-color effects SHALL NOT activate during normal touch interaction on touch-only devices.
-
-#### Scenario: Touch tap on phone
-- **WHEN** user taps a button on a touch-only device (phone, tablet without keyboard/D-pad)
-- **THEN** the button SHALL NOT show the focus inverse-color effect; standard Material 3 ripple/press behavior SHALL be preserved
-
-### Requirement: No new abstraction files
-Focus inverse-color implementations SHALL use shared utility functions from `util/focus/FocusHighlight.kt` rather than inline per-element boilerplate. New interactive components SHALL adopt `rememberIsFocused()` (for `IconButton`, `DropdownMenuItem`, clickable surfaces) or `rememberInteractionFocus()` (for `Button`, `OutlinedButton`, `TextButton`) instead of re-implementing `onFocusChanged` + `mutableStateOf` or `MutableInteractionSource` + `collectIsFocusedAsState` + `collectIsPressedAsState`.
-
-The two utility functions (`rememberIsFocused()` and `rememberInteractionFocus()`) SHALL be the single source of truth for focus state tracking. When a bug is found in focus state logic, it SHALL be fixed once in the utility file, not in each screen.
-
-#### Scenario: Adding a new IconButton with focus
-- **WHEN** a developer adds a new `IconButton` to any screen that needs D-pad focus highlighting
-- **THEN** they SHALL use `val (isFocused, focusModifier) = rememberIsFocused()` and attach `focusModifier` to the button, reading `isFocused` for `containerColor` and `contentColor`
-- **AND** they SHALL NOT write a new `mutableStateOf(false)` + `onFocusChanged` block
-
-#### Scenario: Adding a new TextButton with focus
-- **WHEN** a developer adds a new `TextButton` to any screen that needs D-pad focus highlighting
-- **THEN** they SHALL use `val (isActive, interactionSource) = rememberInteractionFocus()` and pass `interactionSource` to the button, reading `isActive` for colors
-- **AND** they SHALL NOT write a new `MutableInteractionSource` + `collectIsFocusedAsState` + `collectIsPressedAsState` block
-
-#### Scenario: Code review of a single screen
-- **WHEN** an upstream reviewer inspects the diff of any single screen file
-- **THEN** the focus inverse-color logic SHALL reference `rememberIsFocused()` or `rememberInteractionFocus()` from `util/focus/FocusHighlight.kt`, which is self-documenting and reviewable once
-
-### Requirement: ListItem focus styling
-When `ListItem`-based components (settings toggles, slider rows) receive focus, the entire row SHALL highlight with `surfaceVariant` background. The headline and supporting text SHALL transition to `primary` color, except where `primary` would conflict with embedded controls (e.g., Switch toggles, Slider tracks).
-
-#### Scenario: Settings toggle row receives focus
-- **WHEN** D-pad navigation focuses a `SwitchPref` or `SettingsItem` row
-- **THEN** the row background becomes `surfaceVariant`, headline text becomes `primary`, and the Switch control remains its default coloring
-
-### Requirement: Slider D-pad navigation
-All `Slider` components SHALL respond to D-pad left/right key events. The step increment SHALL be configurable per slider via a `dpadStep` parameter; when not specified, the slider SHALL use a sensible default based on its range and step count.
-
-#### Scenario: D-pad right on a slider
-- **WHEN** a Slider has focus and the user presses D-pad Right
-- **THEN** the slider value increases by the configured step amount
-
-#### Scenario: D-pad left on a slider
-- **WHEN** a Slider has focus and the user presses D-pad Left
-- **THEN** the slider value decreases by the configured step amount
-
-### Requirement: Slider focus indicated by thumb animation
-The `Slider` component SHALL indicate D-pad focus through thumb animations (size increase + white border). The track colors (play progress, buffered, unplayed) SHALL remain unchanged when focus changes.
-
-#### Scenario: Slider receives D-pad focus
-- **WHEN** D-pad navigation focuses the slider
-- **THEN** the thumb grows from 15dp to 20dp
-- **AND** a 3dp white border appears around the thumb
-- **AND** the track colors (play progress, buffered, unplayed) remain unchanged
-
-#### Scenario: Slider loses D-pad focus
-- **WHEN** D-pad focus moves away from the slider
-- **THEN** the thumb shrinks from 20dp to 15dp
-- **AND** the white border disappears
-- **AND** the track colors remain unchanged
-
-#### Scenario: Touch interaction on slider
-- **WHEN** user touches or drags the slider on a touch-only device
-- **THEN** the slider does NOT show the focus thumb animation
-- **AND** the standard touch interaction (drag/tap) works normally
-
-### Requirement: Side sheet selected item is visually prominent
-The currently selected item in the speed and resize side sheets SHALL display in `primary` color AND bold font weight to clearly distinguish it from unselected items.
-
-#### Scenario: Selected speed option is bold
-- **WHEN** the speed side sheet is open
-- **AND** a speed option (e.g., "1.0X") is the currently active value
-- **THEN** that item's text is displayed in `primary` color AND `FontWeight.Bold`
-
-#### Scenario: Selected resize option is bold
-- **WHEN** the resize side sheet is open
-- **AND** a resize option (e.g., "适应") is the currently active value
-- **THEN** that item's text is displayed in `primary` color AND `FontWeight.Bold`

-# TV Focus Traversal
-
-## Purpose
-
-Ensure predictable vertical and horizontal D-pad focus flow for complex Compose layouts where items span different widths or overlap, using direction-key interception and focus group isolation to override Compose's default 2D spatial algorithm when it produces wrong targets.
-
-## Requirements
-
-### Requirement: Vertical focus flows through layout rows in order
-Interactive elements in vertically stacked layouts (Column or scrollable equivalent) SHALL transfer focus in visual row order when the user presses up/down on D-pad, regardless of horizontal position differences between elements in adjacent rows.
-
-#### Scenario: Episodes row to controls row (detail page)
-- **WHEN** D-pad focus is on any episode button in the episodes `LazyRow`
-- **THEN** pressing DOWN moves focus to the first focusable item in the `EpisodeListControl` row directly below
-- **AND** pressing UP moves focus to the control above the episodes row
-
-#### Scenario: Controls row to related row (detail page)
-- **WHEN** D-pad focus is on any control button (channel, reverse, or more episodes)
-- **THEN** pressing DOWN moves focus to the first item in the related anime `LazyRow`
-- **AND** pressing UP moves focus to the last played episode button in the row above
-
-#### Scenario: Favourite button to last played episode (detail page)
-- **WHEN** D-pad focus is on the FavouriteIcon (heart button)
-- **THEN** pressing DOWN moves focus to the last played episode button
-
-#### Scenario: Reverse list preserves last played focus (detail page)
-- **WHEN** user toggles reverse list
-- **AND** presses UP from EpisodeListControl
-- **THEN** focus moves to the last played episode button (not a different episode)
-
-#### Scenario: Theme mode to switch rows (settings page)
-- **WHEN** D-pad focus is on a theme mode `SegmentedButton` (System, Light, or Dark)
-- **THEN** pressing DOWN moves focus to the first focusable item below the color swatch row (the Dynamic Color switch)
-- **AND** pressing UP moves focus to an element above the theme mode row
-
-### Requirement: Color swatch row accepts only horizontal focus traversal
-The `ColorBall` color swatch `LazyRow` in the appearance settings SHALL only accept horizontal (←/→) focus movement. Vertical (↑/↓) key events originating from within the swatch row SHALL be intercepted and redirected to the logical row above or below.
-
-#### Scenario: Vertical key intercepted inside color swatch row
-- **WHEN** D-pad focus is on any color circle inside the `ColorBall` LazyRow
-- **THEN** pressing UP moves focus to the theme mode `SegmentedButtonRow` above
-- **AND** pressing DOWN moves focus to the Dynamic Color `SwitchPref` below
-- **AND** pressing LEFT or RIGHT navigates between color circles within the row (standard behavior)
-
-#### Scenario: Entering the color swatch row from above
-- **WHEN** D-pad focus is on the theme mode selector
-- **AND** user presses RIGHT (or final → moves focus right)
-- **THEN** focus enters the `ColorBall` LazyRow at the first visible color circle
-
-#### Scenario: Exiting the color swatch row to below
-- **WHEN** D-pad focus is on the rightmost color circle in the `ColorBall` LazyRow
-- **AND** user presses RIGHT
-- **THEN** focus moves to the Dynamic Color `SwitchPref` below (or wraps to the next logical control)
-
-### Requirement: Focus highlight uses a shared inverse-color modifier
-All interactive elements SHALL use `rememberIsFocused()` instead of requiring per-element `var isFocused by remember` + `Modifier.onFocusChanged` boilerplate.
-
-#### Scenario: Applying focus highlight to a button
-- **WHEN** a composable uses `rememberIsFocused()` to obtain `(isFocused, focusModifier)`
-- **AND** the composable receives D-pad focus
-- **THEN** the `isFocused` state becomes `true`, allowing the composable to apply `primary` background and `onPrimary` content color
-
-### Requirement: D-pad direction keys can be intercepted at layout boundaries
-The `Modifier.handleDPadKeyEvents()` extension SHALL allow composables to intercept and handle D-pad direction events (up/down/left/right/enter) before child composables process them, using `onPreviewKeyEvent` priority.
-
-#### Scenario: Intercepting a down press at a vertical boundary
-- **WHEN** a composable uses `Modifier.handleDPadKeyEvents(onDown = { customAction() })`
-- **AND** the composable (or any child) has focus
-- **AND** user presses D-pad DOWN
-- **THEN** `customAction()` is invoked
-- **AND** the key event is consumed (not propagated to children)
-
-#### Scenario: Passing through a non-intercepted direction
-- **WHEN** a composable uses `Modifier.handleDPadKeyEvents(onDown = { ... })` without setting `onLeft`
-- **AND** user presses D-pad LEFT
-- **THEN** the left key event is NOT consumed and propagates to child composables normally

之前的 .gitignore 把整个 .github 目录一并忽略，并连带删除了工作流的跟踪，
这里恢复 android_ci.yml / release.yml。

仅本地使用的笔记（docs/、AGENTS.md）不再跟踪，改由 .git/info/exclude 管理，
避免混进 PR 给评审增加噪音。

顺带回退 app/build.gradle.kts 中「release 签名缺失时回退到 debug 签名」的
改动，构建脚本保持与上游一致。

-## Project overview
-
-Animius is a multi-source Android anime streaming app. Kotlin/Jetpack Compose, MVVM + Clean Architecture. 4 Gradle modules.
-
-## Module structure
-
-| Module | Package | Purpose | Compose? |
-|---|---|---|---|
-| `:app` | `com.lanlinju.animius` | Main app — UI, data, DI, all features | Yes |
-| `:video-player` | `com.lanlinju.videoplayer` | ExoPlayer/Media3 video player wrapper | Yes |
-| `:download` | `com.lanlinju.download` | HTTP/M3U8 download engine (OkHttp + Retrofit) | No |
-| `:danmaku` | `com.anime.danmaku` | Danmaku (bullet comment) rendering engine | Yes |
-
-Dependency graph: `app` → `video-player`, `app` → `download`, `app` → `danmaku`. No cross-deps between library modules.
-
-## Build
-
-```bash
-./gradlew assembleDebug          # debug APK
-./gradlew assembleRelease        # release APK (needs signing env vars)
-```
-
-- **Gradle 8.14**, AGP 8.11.0, Kotlin 2.2.0, JVM target 17
-- Version catalog: `gradle/libs.versions.toml` (single source of truth for versions)
-- compileSdk 36, minSdk 26, targetSdk 36
-
-## Tests
-
-```bash
-./gradlew test                       # all JVM unit tests
-./gradlew :app:test                  # app module unit tests only
-./gradlew :danmaku:test              # danmaku module unit tests only
-./gradlew connectedAndroidTest       # instrumented tests (needs device/emulator)
-```
-
-- JUnit 4 throughout. Some tests hit real network (source parsers, Dandanplay client).
-- DAO tests use Room in-memory DB (instrumented only).
-- **Tests are NOT run in CI** — CI only runs `assembleDebug`/`assembleRelease`.
-- No lint/format/static analysis tools configured (no detekt, ktlint, spotless, or .editorconfig).
-
-## Code generation
-
-KSP is used for:
-- **Hilt** (`com.google.dagger:hilt-compiler`) — DI boilerplate
-- **Room** (`androidx.room:room-compiler`) — DAO implementations
-
-Room schemas are exported to `app/schemas/` (required for migration testing).
-
-## Secrets / env vars
-
-Build-time environment variables (no .env files in repo):
-- `DANDANPLAY_APP_ID` / `DANDANPLAY_APP_SECRET` — DanDanPlay danmaku API credentials (injected into `BuildConfig`)
-- `KEY_STORE_PASSWORD` / `KEY_ALIAS` / `KEY_PASSWORD` — APK signing (release only)
-
-Debug builds work without any env vars set.
-

-**Source system**: 11 anime site scrapers implement `AnimeSource` interface (`getHomeData`, `getAnimeDetail`, `getVideoData`, `getSearchData`, `getWeekData`). `SourceHolder` singleton manages active source at runtime.
-
-**Navigation**: Type-safe sealed `Screen` class with Kotlinx Serialization routes in `presentation/navigation/`.
-
-**Crash handler**: Runs in separate `:error_handler` process via `CrashActivity`. Global uncaught exception handler in `MainActivity`.
-
-## Key gotchas
-
-- Source parsers use Jsoup to scrape live websites — they break when sites change markup. Tests for these exist but rely on local HTML fixtures or real network calls.
-- `AnimeApplication.getInstance()` exposes a static context — used by `SourceHolder` and `Preferences` outside DI.
-- Release builds have `isMinifyEnabled = true` + `isShrinkResources = true` with ProGuard. `SourceMode` enum is kept explicitly in `proguard-rules.pro`.
-- `download` module is pure Kotlin (no Compose). `video-player` and `danmaku` are Compose libraries.

-# TV Remote Control Support Implementation Plan
-
-> [!NOTE]
-> This document may not reflect the current implementation.
-> See the final report for up-to-date state:
-> [Final Report](../reports/tv-remote-support.md)
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use compose:subagent (recommended) or compose:execute to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Add D-pad remote control support to the video player and improve focus highlight visibility across the app for Android TV.
-
-**Architecture:** Add focusable modifiers + focus border visual feedback to all interactive elements in `VideoPlayerControl`. Enhance `defaultRemoteControlHandler` in `VideoPlayScreen` for full D-pad navigation. Extract a reusable `tvFocusBorder` modifier. Adjust existing focus border styles in other screens.
-
-**Tech Stack:** Jetpack Compose, Media3 ExoPlayer, standard Material3 (no TV Material3 dependency)
-
----
-
-### Task 1: Create reusable TV focus border modifier
-
-**Covers:** [S2]
-
-**Files:**
-- Modify: `video-player/src/main/java/com/lanlinju/videoplayer/VideoPlayerControl.kt`
-
-- [ ] **Step 1: Add focus border modifier at the top of VideoPlayerControl.kt**
-
-Add these imports after the existing imports (around line 39):
-
-```kotlin
-import androidx.compose.foundation.border
-import androidx.compose.foundation.focusable
-import androidx.compose.foundation.interaction.MutableInteractionSource
-import androidx.compose.foundation.interaction.collectIsFocusedAsState

-import androidx.compose.foundation.shape.RoundedCornerShape
-import androidx.compose.ui.focus.focusRequester
-import androidx.compose.ui.focus.onFocusChanged
-import androidx.compose.ui.unit.IntSize

-
-Then add this modifier function after the `safeValue()` function (around line 291):
-
-```kotlin
-private val FocusBorderShape = RoundedCornerShape(8.dp)
-
-@Composable
-private fun Modifier.tvFocusBorder(
-    interactionSource: MutableInteractionSource,

-        contentAlignment = Alignment.Center
-    ) {

-
-- [ ] **Step 1: Update AdaptiveTextButton to use interactionSource for focus**
-
-Replace the `AdaptiveTextButton` composable (lines 326-344) with:
-
-```kotlin
-@Composable
-fun AdaptiveTextButton(
-    text: String,
-    modifier: Modifier = Modifier,
-    onClick: () -> Unit,
-    color: Color = LocalContentColor.current,
-    style: TextStyle = MaterialTheme.typography.bodyMedium
-) {
-    val interactionSource = remember { MutableInteractionSource() }
-    AdaptiveIconButton(
-        modifier = modifier.size(MediumIconButtonSize),
-        onClick = onClick,
-        interactionSource = interactionSource

-            color = color,
-            style = style,
-        )
-    }
-}
-```
-
-Key change: Creates and passes its own `interactionSource` so the focus border works.

-
-Update the `VideoPlayerControl` function signature to accept a `modifier` parameter:
-
-```kotlin
-@Composable
-fun VideoPlayerControl(
-    state: VideoPlayerState,
-    title: String,
-    subtitle: String? = null,
-    background: Color = Color.Black.copy(0.2f),

-    onDanmakuClick: (Boolean) -> Unit = {},
-    optionsContent: (@Composable () -> Unit)? = null,
-    modifier: Modifier = Modifier,

-```
-
-Then update the internal Box to use this modifier:
-
-```kotlin

-
-            else -> false
-        } else {
-        false
-    }

-```
-
-Key changes:
-- Changed from `KeyDown` to `KeyUp` to prevent repeat-firing (matching JetStreamCompose pattern)
-- Changed `DirectionUp` from `showEpisodeUi()` to `showControlUi()` (episode UI is accessed via the episode button in the control bar)
-- Changed `DirectionDown` to only show control UI + play next (removed redundant `showControlUi()`)

-
-Also add the `isFocused` state and imports:
-
-```kotlin
-import androidx.compose.foundation.border
-import androidx.compose.ui.focus.onFocusChanged
-```
-
-And in the `itemsIndexed` block, add:
-
-```kotlin
-var isFocused by remember { mutableStateOf(false) }
-```
-
-And update the modifier chain:
-
-```kotlin
-.onFocusChanged { isFocused = it.isFocused }
-```
-
-- [ ] **Step 2: Add focus border to SearchScreen search result items**
-
-In `SearchScreen.kt`, update the `MediaSmall` modifier block to add a focus border when focused on TV.
-
-Add imports:
-
-```kotlin
-import androidx.compose.foundation.border
-import androidx.compose.foundation.shape.RoundedCornerShape
-```
-
-Update the modifier chain (around line 211-222) to add:
-
-```kotlin
-.border(

-# TV Remote Control Support — Final Report
-
-## What Was Built
-
-Added D-pad remote control support to the video player and improved focus highlight visibility across the app for Android TV. The video player now supports full D-pad navigation: left/right to seek, up to show controls, down for next episode, center/enter to play/pause. All player control buttons (play/pause, next, danmaku, speed, resize, episode selector) display a 2dp primary-color border when focused. The progress slider supports D-pad left/right seeking with visual feedback. On Android TV, focus is automatically applied to the first control button when the control overlay appears. Other screens (anime detail episode buttons, search result items) also received improved focus border visibility.
-
-## Architecture
-
-### Files Modified
-
-| File | Changes |
-|------|---------|
-| `video-player/.../VideoPlayerControl.kt` | Added `tvFocusBorder` modifier, wired into `AdaptiveIconButton` and `AdaptiveTextButton`, added `modifier` parameter to `VideoPlayerControl` |
-| `video-player/.../component/Slider.kt` | Added focusable, focus border, D-pad key handling (left/right seek, center confirm) |
-| `app/.../videoplayer/VideoPlayerScreen.kt` | Enhanced `defaultRemoteControlHandler` (KeyUp instead of KeyDown), added auto-focus on TV via `FocusRequester` + `LaunchedEffect` |
-| `app/.../detail/AnimeDetailScreen.kt` | Added focus border to episode buttons |
-| `app/.../search/SearchScreen.kt` | Added focus border to search result items |
-
-### Key Components
-
-- **`tvFocusBorder` modifier** — Reusable Compose modifier that shows a 2dp primary-color `RoundedCornerShape(8.dp)` border when an element has D-pad focus. Uses `MutableInteractionSource.collectIsFocusedAsState()` for idiomatic focus tracking.
-- **`defaultRemoteControlHandler`** — `Modifier.onKeyEvent` extension mapping D-pad keys to player actions. Consumes events on `KeyUp` (not `KeyDown`) to prevent repeat-firing.
-- **Auto-focus on TV** — `LaunchedEffect` watches `isControlUiVisible` and requests focus on the first control button via `FocusRequester` when controls appear on Android TV.
-
-### Design Decisions
-
-- **Plain Material3 + manual focus** (not TV Material3) — Minimizes migration risk, phone and TV share the same UI code with `isAndroidTV()` checks for focus behavior only.
-- **KeyUp consumption** — Prevents D-pad repeat-firing that caused unintended rapid seek/play-pause toggling.
-- **2dp primary border** — Visible but unobtrusive; uses `MaterialTheme.colorScheme.primary` for consistency with the app theme.
-
-## Verification
-
-- `./gradlew assembleDebug` — BUILD SUCCESSFUL (128 tasks)
-- `./gradlew :video-player:compileDebugKotlin` — BUILD SUCCESSFUL
-- `./gradlew :app:compileDebugKotlin` — BUILD SUCCESSFUL (only pre-existing deprecation warnings)
-- All imports verified correct across all modified files
-- No new warnings introduced
-
-## Journey Log
-
-- [lesson] `collectIsFocusedAsState()` requires `import androidx.compose.runtime.getValue` for `by` delegate — missing import caused initial compilation failure
-- [lesson] Gradle 8.14 distribution download can timeout on slow networks — use Android Studio bundled JDK at `C:\Program Files\Android\Android Studio\jbr` as fallback

-# [S1] 动漫源切换统一改造
-
-## [S2] 问题
-
-- Week 和 Home 页面切换源功能不统一：Week 页面用 AlertDialog + RadioButton，Home 页面无切换功能
-- 切换源后只有当前页面刷新，其他页面不同步
-- Week 页面切换源需要点击确认按钮，操作繁琐
-- Home 页面站源文本无焦点样式，不能使用 D-pad 操作
-
-## [S3] 改动的文件
-
-| 文件 | 改动 |
-|------|------|
-| `util/SourceHolder.kt` | `isSourceChanged` 改为 `mutableStateOf(0)` 计数器 |
-| `screen/week/WeekScreen.kt` | `SourceSwitchDialog` 改为 public，添加 `onSourceChanged` 回调，移除确认/取消按钮 |
-| `screen/home/HomeScreen.kt` | 站源文本改为 `Surface(onClick)` + `SourceSwitchDialog`，添加 `focusGroup()` |
-| `screen/home/HomeScreen.kt` | 站源使用 `surfaceVariant.copy(alpha = 0.6f)` 焦点背景色 |
-
-## [S4] 关键实现
-
-1. **跨页面刷新**: `SourceHolder.isSourceChanged` 用 `mutableStateOf(0)` 递增计数器代替布尔值
-2. **Week 页面**: `SourceSwitchDialog` 改为 public，选中 RadioButton 立即切换并刷新
-3. **Home 页面**: 站源名称用 `Surface(onClick) + RoundedCornerShape(20.dp)` + `sourceSwitchDialog` 弹出相同源选择列表
-4. **焦点背景**: `onFocusChanged` + `surfaceVariant.copy(alpha = 0.6f)` 统一圆角矩形效果

-# Focus Border & Long Press Spec
-
-## MediaSmall Focus Border
-
-### Component
-`MediaSmall` in `app/src/main/java/com/lanlinju/animius/presentation/component/MediaSmall.kt`
-
-### Behavior
-When a `MediaSmall` card receives D-pad focus, a **3dp white rounded-corner border** appears around the card. When focus leaves, the border disappears (0dp/transparent).
-
-### Implementation
-```
-Card(onClick) → modifier.onFocusChanged → modifier.border(Color.White, 3dp, cardShape)
-```
-
-- `Card(onClick)` makes the card focusable by default (no extra `focusable()` needed)
-- `onFocusChanged` tracks `isFocused` state
-- `border` conditionally renders 3dp white border when focused, 0dp transparent when not
-- Card retains default Material3 elevation, ripple, and dimming on focus
-
-### Key discovery
-`LazyRow` and `LazyVerticalGrid` do NOT forward D-pad focus to individual items by default. Must add `Modifier.focusGroup()` to the container:
-
-- `MediaSmallRow` → `LazyRow(modifier = Modifier.focusGroup())`
-- HomeScreen `LazyVerticalGrid` → `.focusGroup()`
-- FavouriteScreen `LazyVerticalGrid` → `.focusGroup()`
-
-### What doesn't work (abandoned approaches)
-- **Box wrapper + border**: Card's internal focus indicator overrides outer border
-- **`combinedClickable` + `focusable()`**: `combinedClickable` steals focus, `onFocusChanged` never fires
-- **`clickable(indication = null)` + `focusable()`**: Card never receives focus
-- **ClassicCard (TV Material3)**: Not clickable on physical phone devices
-- **Color inversion for dark theme**: Makes cards darker, not brighter
-

-
-## Favourite Screen Long Press Menu
-
-### Behavior
-Long press on a favourite card shows a delete confirmation menu. Short press navigates to detail page.
-
-| Input | Short Press | Long Press |
-|-------|-------------|------------|
-| Touch | Navigate to detail | Show delete menu (no navigation) |
-| D-pad (Center button) | Navigate to detail | Show delete menu (no navigation) |
-
-### Implementation
-Long press is handled in `FavouriteScreen` (NOT in `MediaSmall`), using two independent mechanisms:
-
-#### Touch long press
-```
-Modifier.pointerInput → awaitEachGesture → awaitFirstDown → track touchPressed state
-LaunchedEffect(touchPressed) → delay(longPressTimeout) → show menu
-```
-
-- `pointerInput` detects finger down/up via `awaitEachGesture`
-- Sets `touchPressed = true` on down, `false` on up
-- `LaunchedEffect(touchPressed)` starts a timer when finger goes down
-- If finger lifts before timeout → `touchPressed = false` → effect cancelled (short press)
-- If timeout fires → `longPressConsumed = true` → show menu
-
-#### D-pad long press
-```
-Modifier.onPreviewKeyEvent → Center KeyDown → Handler.postDelayed(longPressTimeout) → show menu
-                         → Center KeyUp → Handler.removeCallbacksAndMessages → manual onClick
-```
-
-- `onPreviewKeyEvent` consumes Center key events (returns `true`), preventing Card's internal click handling
-- KeyDown starts a `Handler.postDelayed` timer
-- KeyUp cancels the timer. If timer hadn't fired (short press), manually calls `onNavigateToAnimeDetail()`
-- `DisposableEffect(Unit)` cleans up Handler when composable leaves the tree
-
-#### Shared flag
-```
-var longPressConsumed by remember { mutableStateOf(false) }
-```
-
-- Set to `true` when long press is detected (by either mechanism)
-- Card's `onClick` checks: `if (!longPressConsumed) { navigate }`
-- Reset to `false` after check (prevents stale state from blocking future clicks)
-
-### Files
-- `app/.../favourite/FavouriteScreen.kt` — all long press logic lives here
-- `app/.../component/MediaSmall.kt` — no long press logic, pure Card + border + focus
-
-### Why long press is NOT in MediaSmall
-MediaSmall is shared across Home, Favourite, Detail, and Search screens. Only Favourite needs long press. Putting it in MediaSmall would:
-- Add `onLongClick` parameter to all callers
-- Risk Handler/LaunchedEffect leaks across screen navigations
-- Couple a UI component with screen-specific behavior
-
-### Why `onPreviewKeyEvent` consumes D-pad events
-`Card(onClick)` internally handles Center key as a click. Without consuming, both Card's onClick AND the long press timer would fire. Consuming lets us control the flow: short press → manual onClick, long press → menu only.
-
-### What doesn't work (abandoned approaches)
-- **`detectTapGestures` on Box wrapper**: Consumes events, breaks Card's onClick
-- **`combinedClickable` on Box wrapper**: Steals focus from inner Card, border disappears
-- **`pointerInput` + `consume()` after long press**: Breaks `awaitEachGesture` loop, all subsequent gestures fail
-- **LaunchedEffect for D-pad**: Timing inconsistency with key events vs coroutine scheduling
-- **Handler without DisposableEffect**: Leaked callbacks fire after screen navigation

-# Focus Inverse Color — Implementation Spec
-
-## Problem
-
-Buttons across the app (detail page, search page, video player, etc.) used a default dimming or no effect when focused via D-pad/remote, making it hard to distinguish the focused element. The goal was to replace this with a clear inverse-color effect: focused button gets `primary` background with `onPrimary` content, applied uniformly across all devices (phone, tablet, TV).
-
-## Affected Components
-
-| Component | Composable | Button type |
-|---|---|---|
-| Back button | `TopAppBar.navigationIcon` | `IconButton` |
-| More menu | `TopAppBar.actions` | `IconButton` |
-| Favorite heart | `FavouriteIcon` | `IconButton` |
-| Episode pills | `AnimeEpisodes` | `FilledTonalButton` |
-| Reverse list | `EpisodeListControl` | `Text` → wrapped in `Box` |
-| More episodes | `EpisodeListControl` | `Row` |
-| Channel selector | `EpisodeListControl` | `Text` → wrapped in `Box` |
-| Episode chips (bottom sheet) | `EpisodeBottomSheet` | `SuggestionChip` |
-
-## Implementation Patterns
-
-### Pattern A: Components with `interactionSource` support (`FilledTonalButton`, `SuggestionChip`)
-
-Use the component's built-in `interactionSource` parameter + `collectIsFocusedAsState()` / `collectIsPressedAsState()`.
-
-```
-val interactionSource = remember { MutableInteractionSource() }
-val isFocused by interactionSource.collectIsFocusedAsState()
-val isPressed by interactionSource.collectIsPressedAsState()
-val isActive = isFocused || isPressed
-
-Component(
-    interactionSource = interactionSource,
-    colors = ...(
-        containerColor = when {
-            isActive -> MaterialTheme.colorScheme.primary
-            else -> defaultColor
-        }
-    )
-)
-```
-
-Do NOT add explicit `.onFocusChanged` or `.focusable()` modifiers — the component handles these internally via `interactionSource`.
-
-**Why `isActive = isFocused || isPressed`**: Prevents a visual flash when the user clicks — if only `isFocused` were used, the color would revert to default during the press-down phase before navigation fires.
-
-### Pattern B: Components without `interactionSource` (`IconButton`, `Box`/`Row` wrappers)
-
-Use `.onFocusChanged` modifier + `mutableStateOf`.
-
-```
-var isFocused by remember { mutableStateOf(false) }
-
-Component(
-    modifier = Modifier
-        .onFocusChanged { isFocused = it.isFocused }
-        .clickable(onClick = ...),
-    colors = ...(
-        containerColor = when {
-            isFocused -> MaterialTheme.colorScheme.primary
-            else -> defaultColor
-        }
-    )
-)
-```
-
-**On touch-only devices (phones/tablets)**: `onFocusChanged` is harmless — it simply never fires without focus navigation (keyboard, D-pad, TV remote).
-
-### Color Rules
-
-All components follow the same color mapping:
-
-| State | Background | Content (icon/text) |
-|---|---|---|
-| Not focused (default) | `surfaceVariant.copy(alpha = 0.45f)` / `Color.Transparent` or component default | `primary` / `onSurface` or component default |
-| Focused / Pressed | `MaterialTheme.colorScheme.primary` | `MaterialTheme.colorScheme.onPrimary` |
-
-> Note: Components on dark/overlay backgrounds (e.g. `TopAppBar` buttons over a banner) may use `Color.Transparent` + `White.copy(alpha = 0.85f)` as the default unfocused state instead of `surfaceVariant`.
-
-### Background Addition
-
-Components that originally had no background (`Text` with `clickable`:
-- Reverse list, More episodes, Channel selector) were wrapped in a `Box` (or kept as `Row`) with:
-  - `.clip(RoundedCornerShape(8.dp))`
-  - `.background(...)` with the conditional color
-  - `.padding(horizontal = 12.dp, vertical = 3.dp)` for compact sizing
-  - Vertical offset increased from `large_padding + 6.dp` to `large_padding + 16.dp` to prevent overlap with episode buttons above
-
-### Pitfalls Encountered
-
-1. **`.let {}` with `Modifier`**: Using `.let { if (cond) it.focusable() else it }` broke click handling. The plain `Modifier` returned from the else branch caused unexpected behavior. Fixed by using direct modifier calls instead of conditional `.let` chains.
-
-2. **Redundant `.focusable()`**: Adding explicit `.focusable()` before `.clickable()` can interfere with `clickable`'s internal focus handling. Since `clickable` (and button components) already add `focusable()`, never add it manually.
-
-3. **`onFocusChanged` vs `interactionSource`**: For components that support `interactionSource` (buttons, chips), prefer `interactionSource.collectIsFocusedAsState()` over `onFocusChanged` — it's synchronized with the component's own state machine and avoids timing issues.
-
-4. **Missing `interactionSource` parameter**: Creating a `MutableInteractionSource` and using `collectIsFocusedAsState()` on it is useless if the component doesn't receive that `interactionSource` parameter. Always pass it explicitly.
-
-## Focus Behavior Note
-
-The inverse color effects apply on **all devices** (phone, tablet, TV) whenever a component gains focus via D-pad, keyboard, or TV remote. On touch-only devices, `onFocusChanged` never fires during normal touch interaction, so the effects are effectively invisible — touch behavior is completely unchanged.
-
-This means no `isAndroidTV` guards are needed. The `.onFocusChanged` modifier and `interactionSource.collectIsFocusedAsState()` are harmless on non-TV devices.

两个 workflow 的 "Set up Android SDK" 步骤挂在构建之前,后续步骤全被 skip:
job 11~18 秒就结束,日志里没有 Gradle 输出。原因是
android-actions/setup-android 会比对镜像里的 cmdline-tools 版本,不一致就自行
下载它固定绑定的那一版,而 Google 已把这些 zip 从仓库下架:

    Downloading commandline tools from .../commandlinetools-*-<rev>_latest.zip
    HTTPError: Unexpected HTTP response: 404

上游 issue android-actions/setup-android#536 自 8 月起开着且没有修复版,
最新版 v4 同样中招。GitHub 把 Node20 的 action 强制跑在 Node24 上后又放大了
这个问题(见 check run 注解)。

判定为环境问题而非本仓库代码问题的依据:同一份 workflow、同一行 @v3,
在 main 上 2026-05-29 是成功的,2026-09 全挂。

修法:直接删掉该步骤。ubuntu-latest 镜像已经预装本项目需要的 SDK 并且
已接受许可,这一步本来也是多余的:
  ANDROID_HOME=/usr/local/lib/android/sdk
  cmdline-tools 12.0 / platform-tools 37.0.1
  platforms;android-36(本项目 compileSdk = 36)
  build-tools 37.0.0 / 36.0.0 / 36.1.0 / 35.x / 34.0.0

顺带 actions/setup-java@v4 -> @v5(v4 已被官方标记弃用,见同一处注解)。
未改动任何构建逻辑。

详情页把焦点停在剧集控制行（线路/正序/更多）按遥控器 ↓ 时，抛
IllegalStateException: FocusRequester is not initialized。

firstRelatedFocusRequester 只在 AnimeRelated 的 LazyRow index == 0 的卡片上挂
Modifier.focusRequester()。当该卡片被 LazyRow 回收（或在相关推荐为空的页面
从未挂上）时，修饰符从焦点树上摘除，requester 变为未初始化，此时
requestFocus() 直接抛异常。

修复：

- EpisodeListControl 的 onDownFocusRequest 改为可空。DpadKeyHandler 的语义
  本就是「传 null 即放行该方向键」，所以相关推荐为空时不再拦截 ↓。
- 相关推荐为空时整块不渲染，不再留下一个空的标题区块。
- 相关推荐非空但首项已被回收时，requestFocus() 加 runCatching 守卫，
  失败则退回 focusManager.moveFocus(Down) 走默认焦点搜索。

真机验证（Sony BRAVIA 4K VH21 / Android 12 / 1.3.5）：
详情页 → 控制行 → 相关列表右移 14 次使首项回收 → 回控制行 → 按 ↓

- 修复前：必现 FATAL EXCEPTION，进程死亡并跳转崩溃页；产出的崩溃日志与
  用户上报的那份 SHA-256 逐字节相同（BA5AE586…65C79）。
- 修复后：无异常，焦点正常下移到相关推荐卡片。
