Part of #615. PR 1 of plan 101-deep-dive-gaps-bugs — slice 01, tier 0. 92 files.

What lands

Every row of 01-core-schema.md, each behind a failing-first test. None dropped.

Package Rows
core retry / flight-gate bounds; child signal composes the parent's; defineConfig shape and closed-set screens (X_CONFIG_INVALID); Sentry meta nested and scrubbed; credential redaction by compound name; unknown LOG_LEVEL refused; OTLP endpoint / per-signal headers / attribute values; registrar fix: names the owning package; parentbased_always_on; AVIF sniff, PNG inflate bound, zero-size image; X_SECRETS_KEY_INVALID fix; nearestName cutoff; wildcard host rules vs internal address literals; hasPublicCause moved down from http
schema t.date day vs month; coercion (array guard, every union member, decimal only); thenables; plain objects only; .default() checked at declaration; SchemaError parity; t.url
2026-09-28 plan, slice 01 empty ULTIMATE_CURSOR_SECRET= counts as unset
cli X_VERIFY_STEP_TIMEOUT names the test file still running and the killed processes; fix: runs that file; CI job log prints a failed step's last 40 output lines
scripts new-error-code registers into schema's frozen-declaration registry
.claude/commands/feature.md one PR at a time, ≤ ~100 files, several agents inside it, CI green → merge → next

New error code

X_SCHEMA_DEFAULT_INVALID — a .default() value its own schema refuses. Written by the generator; row in wiki/Error-Codes.md.

Breaking

16 BREAKING — entries under [Unreleased] in CHANGELOG.md, each with a row in wiki/Upgrading.md 23.x → 24.0.0. No shim, no deprecated alias.

Not done here

  • The intermittent unit shard hang (run 36970672608) is not root-caused. The failing log named no file; 40 local iterations over the 254 candidate files never hung. The timeout now names the file in flight, so the next occurrence identifies it.
  • DNS half of s2-sec L1: a wildcard allowHosts still admits a hostname that resolves to an internal address. Belongs to scraping / cli connection code — slices 11–12.
  • registerPublicCause bypass: an app can call core's registrar for a framework code and skip http's refusal. Closing it needs core's error registry to record an owner per code.

Decisions taken — overturn freely

  • t.url "href-stable" read as "the parser strips nothing", not new URL(v).href === v (which would refuse https://example.com).
  • retry attempts: 0 still runs once (pinned by an existing test); timeBudgetMs may be fractional or already spent.
  • Empty cache.tiers refused — nothing documents or uses an empty list.
  • Image code changes filed as Fixed, not breaking: refused before and after.

Verified

  • bun run verify: 14 of 14 root steps green (6 app-only steps skip at the framework root).
  • bun run scripts/reference-app-gate.ts: examples/dummy 20/20, dummy/social-media-clone 20/20, 0 pinned.

    • Verification timeout findings now include stalled test details, captured output, and targeted rerun commands when the affected file can be identified.
    • Structured metadata is available in CLI findings, and public error causes can be registered by applications.
  • Bug Fixes
    • Configuration and schema validation now catch malformed values, invalid defaults, impossible dates, and whitespace in URLs more reliably.
    • Improved credential redaction, OTLP settings, image validation, and protection against wildcard access to private network addresses.
  • Documentation
    • Updated the upgrade guide and changelog for the in-progress 24.0.0 release, including breaking changes.

… config, redaction (#615)

Every row of docs/plans/2026/10/02/101-deep-dive-gaps-bugs/01-core-schema.md, each behind a
failing-first test, none dropped.

core: retry and flight-gate bounds screened; a child context's signal composes its parent's;
defineConfig refuses wrong-shaped and mistyped keys as X_CONFIG_INVALID; credential redaction by
compound name; Sentry meta nested and scrubbed; unknown LOG_LEVEL refused; OTLP endpoint, headers
and attribute fixes; wildcard host rules no longer admit internal address literals; image probe
and PNG inflate bounds; an empty cursor secret counts as unset; hasPublicCause moves down from
http, which imports it and re-exports nothing.

schema: t.date checks the day against the month; t.url takes only what the parser reads as
written; plain objects only; .default() checked at declaration (X_SCHEMA_DEFAULT_INVALID);
decimal-only coercion, every union member tried; thenables; SchemaError parity with UltimateError.

cli: X_VERIFY_STEP_TIMEOUT names the test file still running and the killed processes, and its
fix runs that file. The intermittent unit-shard hang it was built for is not root-caused.

scripts: new-error-code registers into schema's frozen-declaration registry.

BREAKING entries are under [Unreleased] in CHANGELOG.md and wiki/Upgrading.md (23.x -> 24.0.0).

📝 Walkthrough

Walkthrough

The PR updates schema validation and errors, core runtime behavior, and CLI verification timeout diagnostics. It also updates release documentation, upgrade guidance, and the recorded execution plan.

Changes

Schema validation and errors

Layer / File(s) Summary
Schema input validation and coercion
packages/schema/src/*, packages/time/src/plain-date.test.ts, packages/schema/README.md, packages/schema/CLAUDE.md
Schema checks now reject invalid calendar dates, whitespace-padded URLs, non-plain objects, invalid defaults, and thenable results in synchronous validation. Coercion restricts numeric strings and object traversal, and applies union members in declaration order.
Schema defaults and error serialization
packages/schema/src/errors.ts, packages/schema/src/render-meta.ts, packages/schema/src/builder.ts, packages/schema/src/index.ts, packages/schema/src/errors.test.ts, packages/schema/README.md, packages/schema/CLAUDE.md
Invalid defaults use DefaultInvalidError. Schema errors expose terminal retry data, optional documentation formatting, and JSON-safe metadata.
Schema error-code registration
scripts/lib/error-code-plan.ts, scripts/new-error-code.test.ts, scripts/error-map-backlog.ts, packages/schema/src/error-codes.ts, framework.manifest.json, wiki/Error-Codes.md
The error-code generator supports frozen ERROR_CODES declarations. The new X_SCHEMA_DEFAULT_INVALID code is added to the schema backlog, manifest, and reference documentation.

Core runtime behavior

Layer / File(s) Summary
Configuration defaults and validation
packages/core/src/config*.ts, packages/core/src/config*.test.ts, packages/core/src/config-defaults.ts, packages/core/README.md, wiki/Configuration.md
Defaults move to configDefaults. defineConfig checks layer shapes and validates value types, allowed values, locales, and cache tiers. Configuration merging passes through non-object values.
Runtime limits, cancellation, and secret handling
packages/core/src/context.ts, packages/core/src/flight-gate.ts, packages/core/src/retry.ts, packages/core/src/sampler.ts, packages/core/src/cursor.ts, packages/core/src/dev-secrets.ts, packages/core/src/secrets-errors.ts, packages/core/src/registrar.ts, packages/core/src/nearest-name.ts
Child contexts combine parent and child abort signals. Flight-gate and retry limits receive validation. Empty cursor secrets count as unset, and registrar fixes use package-owner mappings.
Cause visibility, redaction, and error reporting
packages/core/src/public-cause.ts, packages/http/src/problem-meta.ts, packages/http/src/error-facts.ts, packages/core/src/logger.ts, packages/core/src/error-reporter-sentry.ts, packages/core/src/*test.ts, packages/core/README.md, packages/core/CLAUDE.md, wiki/Configuration.md
Core provides public-cause registration. Logger and Sentry output redact caller data, and invalid nonempty LOG_LEVEL values are rejected.
Network, telemetry, and image handling
packages/core/src/host-rules.ts, packages/core/src/otlp*.ts, packages/core/src/image/*, packages/core/src/host-rules.test.ts, packages/core/src/otlp.test.ts, packages/core/src/image/*test.ts, wiki/Error-Codes.md
Wildcard host rules reject classified private address literals. OTLP handling updates endpoint paths, signal-specific headers, and numeric attributes. Image handling updates AVIF identification, dimension errors, and PNG inflation bounds.

CLI verification timeout diagnostics

Layer / File(s) Summary
Timeout capture and finding construction
packages/cli/src/verify-deadline.ts, packages/cli/src/verify-stalled.ts, packages/cli/src/verify-run.ts, packages/cli/src/output.ts, packages/cli/src/*deadline.test.ts, packages/cli/src/verify-stalled.test.ts, packages/cli/CLAUDE.md, wiki/CLI-Reference.md, wiki/Testing.md, .github/workflows/ci.yml
Step expiry returns process and in-flight command details. Timeout findings can identify stalled test files, include structured metadata and output, and provide file-specific rerun commands.

Release and execution records

Layer / File(s) Summary
Release notes and sequential PR process
.claude/commands/feature.md, CHANGELOG.md, docs/plans/2026/10/02/101-deep-dive-gaps-bugs/status.yml, wiki/Upgrading.md, framework.manifest.json
The feature workflow now specifies sequential PRs capped at about 100 changed files. The changelog and upgrade guide describe the in-progress 24.0.0 release, and the plan records PR 1 progress and verification notes.

Merge Risk: 🟡 Moderate · up to 84b1d

Logs and error reports can still expose some common credential fields, such as signing or encryption keys and access key IDs. A malformed key-file error also tells operators what to do in prose instead of giving them a command they can run. Fix both before merging; the other review notes are documentation and polish.

Review comments at @.claude/commands/feature.md:
- Line 28: Update the verification workflow in the PR-splitting instructions so
`bun run verify` validates the exact tree intended for each PR. Separate later
PR changes before running the gate, or rerun verification against the exact
staged slice before opening the PR.

Review comments at @CHANGELOG.md:
- Line 54: Update CHANGELOG.md at line 54 and wiki/Upgrading.md at line 99 to
distinguish trimming leading or trailing whitespace from handling interior tab,
CR, or LF characters: instruct readers to remove or encode interior control
characters, since `.trim()` does not remove them. Apply the same complete
migration guidance at both sites.

Review comments at @packages/cli/src/verify-deadline.ts:
- Around line 284-291: Update the command collection in the sweep to run
commandOf for all pids in fresh concurrently, then build commands from the
results before entering the found loop and sending any SIGKILL signals.

Review comments at @packages/core/src/logger.ts:
- Around line 107-117: Expand CREDENTIAL_NAME so isRedactedKey also redacts the
identified signing, encryption, master, HMAC, and secret key names; access key
IDs, auth configuration, connection strings, DSNs, and common token environment
names. Add focused cases in logger-redaction.test.ts for these names to verify
they are redacted.

Review comments at @packages/core/src/secrets-errors.test.ts:
- Around line 104-125: Update the `SecretsKeyInvalidError.fix` expectations so
the file-sourced case verifies the runnable remediation command rather than the
current prose beginning with “edit”; retain checks that the command avoids
interpolating an untrusted key-file path.

Review comments at @packages/core/src/secrets-errors.ts:
- Line 87: Update the file branch of the fix message near renderFixShellArg so
it contains one runnable command, using the escaped input.at path and an
appropriate check or existing x secrets subcommand. Move the key-loss and
recovery explanation into the cause or meta field.

Review comments at @packages/schema/src/builder.ts:
- Line 233: In the default handling flow, update the order of
`assertDefaultValid` and `defaultFactory`: validate `fallback` with
`assertDefaultValid(check, fallback)` before calling `defaultFactory(fallback)`,
so schema-rule failures are reported first.

Review comments at @wiki/Error-Codes.md:
- Line 113: Update the retired-key remediation in the X_SECRETS_KEY_INVALID
entry to instruct readers to correct or remove the named malformed entry in
ULTIMATE_SECRETS_RETIRED_KEYS, rather than using x secrets edit.

…nable secrets fix, stuck file read from Bun's crash line

- core: a name ending in token is redacted unless its qualifier says it is no bearer; key
  material by qualifier; values that embed a credential. X_SECRETS_KEY_INVALID's file fix is a
  command; the retired-keys fix names the entry and the platform variable.
- schema: .default() reports the schema failure before the copy failure.
- cli: on a step timeout the test workers are killed first, so bun test names the file each
  held. Bun wraps a file's output in ::group:: under GitHub Actions and prints a header as
  results stream, so the header diff could not see a stuck file on a runner; it is deleted.
- docs: t.url migration covers an interior tab, CR or LF; feature.md gates the exact tree.

Review round addressed in ecf45cb:

Comment Outcome
feature.md — gate the exact tree fixed: size the PR before briefing; re-gate the exact tree if the cap is overrun
t.url migration, interior controls fixed in CHANGELOG and Upgrading
logger.ts credential names fixed: token suffix fails closed, key material by qualifier, credential-bearing URLs; SSH_AUTH_SOCK kept readable (a socket path); the ReDoS note does not apply (constant alternatives, no nested quantifier)
secrets-errors.ts prose fix + its test fixed: the fix is a command, the explanation moved to the cause
retired-key fix row main claim rejected — x secrets rotate writes the retired keys into the secrets file, so x secrets edit is the right command; wording now also covers a platform-set variable
builder.ts default order fixed: schema failure reported before the copy failure
verify-deadline.ts read command lines before the kill superseded: the sweep was rewritten — workers are killed first and Bun's own crash line names the file
