# M12-03K Status
|
|
|
|
status: done
|
|
task: expose exactly one verified override writer property
|
|
updated: 2026-08-17 America/New_York
|

enablingTask: false
|
|
parityStateChange: false
|
|
|
|
## Scope
|
|
|
|
Schema-1 override writer accepts exactly `SET_M12_OVERRIDE_VALUE` for the property path
|
|
`["m12_override_value"]`. It requires `LOCAL_OVERRIDE`, `readOnly=false`,
|
|
`referenceReadOnly=true`, matching local/reference/hierarchy IDs, and the current revision. A valid
|
|
write updates only the verified value and advances the local revision by one.
|
|
|
|
Linked ownership, a second property path, identity drift, stale revision, malformed fields, and values
|
|
outside the bounded float range are blocked before any writer commit.
|
|
|
|
## Evidence
|
|
|
|
- `npm --prefix web run test:library-override-writer` passed 4/4 unit tests.
|
|
- The valid request applies one property and increments revision exactly once while preserving local
|
|
override ownership and reference read-only semantics.
|
|
- Stale, linked-owner, identity, alternate-operation, alternate-property, malformed, and out-of-range
|
|
requests fail closed.
|
|
|
|
## Artifact Hashes
|
|
|
|
- protocol: `dd181c7e9946b98334a5d1c686887afecfe3fc11d732beec246e40bf11a155aa`
|
|
- unit: `e41bd32eb4ce4d331a20ecb91f3325a27f461b9ae85e98940d5afd482ec21c4c`
|
|
- manifest: `9eeee93e4a806aa59b5c53a6485fe3a1b5e3972c1d2585cdc71b7cfc293afb70`
|
|
- package commands: `cfb232baa494ff59f6c8d65514a08c86332ee9354350b2a0392b6f932a7ee42c`
|
|
|
|
## Next Task
|
|
|
|
`M12-03L`: block override stale source/revision before Main commit.
|
|
|
|
## Rollback
|
|
|
|
Remove the override writer protocol, unit suite, manifest, package command, and this status entry.
|
|
Restore M12-03J to pending and move the machine queue back to `M12-03K`. No parity ledger rollback
|
|
is required.
