# M12-03L Status

status: done
task: block override stale source/revision before Main commit
updated: 2026-08-17 America/New_York
enablingTask: false
parityStateChange: false

## Scope

Schema-1 override freshness binds the local override to its source library ID, source generation,
source revision, dependency-closure SHA-256, invalidation token, and local/reference/hierarchy IDs.
Only a fully matching `COMMIT_OVERRIDE` request reaches `READY`; no Main mutation is performed by
this gate.

Stale generation/revision, dependency closure, invalidation token, linked ownership, identity drift,
alternate operation, malformed token, and undeclared fields return stable blocking codes before Main.

## Evidence

- `npm --prefix web run test:library-override-freshness` passed 4/4 unit tests.
- The exact source generation/revision/closure/token binding returns `READY`.
- Stale source fields return `REVISION_CONFLICT`; local identity drift returns
  `ASSET_SOURCE_HASH_MISMATCH`; linked ownership returns `LINKED_DATA_MUTATION_BLOCKED`.

## Artifact Hashes

- protocol: `2eff7ea7605b1579d7551336d87d4f30adb996b585596ff9eee67aea04ca7d22`
- unit: `d48344f31e1ba12e557ca30ece56643583efa633da556f5de3896a8e9175ef8f`
- manifest: `237f3f168e037b67b805ba8d9c9455250c889a5e90c45cbb17d2d20d9fbdcc50`

## Next Task

`M12-03M`: dependency cycle, ID collision, cross-library cycle, and duplicate reload negatives.

## Rollback

Remove the override freshness protocol, unit suite, manifest, package command, and this status entry.
Restore M12-03K to pending and move the machine queue back to `M12-03L`. No parity ledger rollback
is required.
