# WBV2-P0-003 Status

status: done
task: WBV2-P0-003
gate: G0
updated: 2026-08-24 America/New_York

The capability error-budget contract is now a versioned, bounded protocol slice.
The minimal fixture stores one canonical contract Text datablock with stable
schema and source hashes, an explicit revision, error budget, cancellation
policy, migration policy, and an opaque extension field. Blender desktop and
the rebuilt WASM/Main reader expose the same contract through
`capabilityContractStatus`/`capabilityContract`.

Acceptance evidence:
- generator exit: 0
- desktop field read and save/reopen exit: 0
- `npm --prefix web run test:generated-gap -- --task WBV2-P0-003` exit: 0
- `node tools/web/check-generated-gap.mjs --task WBV2-P0-003` exit: 0
- TypeScript contract check exit: 0
- malformed blend is rejected without changing Main snapshot; unsupported
  schema, duplicate error, over-budget, and schema-hash drift cases are
  recorded as pre-commit rejects

The legacy next-task-plan hash drift was repaired through the repository's
official manifest-update mode, then the protected plan checker and all
execution/context governance gates passed. The queue may advance to the
declared successor without rewriting task history.
