Qualify ContextDaddy usage and allowance migration

[sarthakagrawal927]

Current state

General agent Usage has been retired from CodeVetter source and the public v1.15.0 macOS release:

• [Discussion 1/3] Archive native design evidence #330 archived historical offscreen design evidence.
• [Discussion 2/3] Retire native Usage workspace #331 removed the native Usage workspace; legacy Usage launch routes open Explore.
• [Discussion] Retire general agent usage from CodeVetter #329 removed general codevetter usage and codevetter quota behavior, the bundled ccusage sidecar, and related automation.
• Prepare v1.15.0 Usage retirement release #338 shipped v1.15.0 and added concise ContextDaddy migration errors for callers of the retired CLI commands.

Per-verification token and cost receipts and CodeVetter's local History recovery remain. The v1.15.0 release is published at baa14112 with the signed/notarized arm64 DMG, ZIP, and Sparkle appcast. The release workflow passed migration, relaunch, custom rubric/data preservation, rollback, and manifest gates. pnpm release:manifest:verify -- --tag v1.15.0 reported qualified: true with exactly 3/3 expected assets. The landing deploy is live; /download reports v1.15.0 and the public docs describe the retired workspace.

Decisions and remaining qualification

• Retire general Usage from CodeVetter while preserving per-verification receipts and local History recovery.
• Give codevetter usage and codevetter quota callers explicit migration errors. ContextDaddy has no equivalent CodeVetter CLI command today; scripts need a separately designed replacement if required.
• Qualify native navigation and the legacy Usage launch route on the isolated hosted desktop. Exact-head native CI passed its XCUITest interaction lane, including testRetiredUsageLaunchRouteOpensExplore.
• Publish a signed/notarized release and updated Sparkle appcast after the protected production candidate passed.
• Qualify ContextDaddy's installed general usage and provider allowance behavior against the migration claims. Its public documentation describes coverage, but installed behavior and feature parity have not been established here. Record any gaps before claiming replacement parity.

The local /Applications/CodeVetter.app remains v1.14.3 until the operator updates it; the public v1.15.0 artifact was qualified on an isolated runner. Keep this issue open for the ContextDaddy parity item, without restoring a general Usage surface in CodeVetter.

Release preparation: draft PR #338 carries the v1.15.0 version sync, concise usage/quota migration errors, and docs. Local Rust suite, clippy, CLI qualification, version consistency, docs, format, and lint passed. Exact-head PR CI is running. Protected hosted production-candidate qualification was dispatched as run 36170545269; it signs, notarizes, and checks migration without publishing. Merging #338 would trigger auto-release, so it remains draft pending those receipts and owner approval to publish. The public app and download page remain v1.14.3.
