# M12-03J Status

status: done
task: desktop override fixture records reference, local owner, and property override path
updated: 2026-08-17 America/New_York
enablingTask: false
parityStateChange: false

## Scope

Blender 5.2 creates a real linked Object and converts it through the library override API. The fixture
records the linked reference as `SOURCE_LIBRARY/readOnly=true`, the local hierarchy root as
`LOCAL_OVERRIDE/readOnly=false`, and one explicit custom-property override path. The source marker,
reference ID, local owner, hierarchy root, property operation and value remain stable after save/reopen.

This fixture does not open a general override writer; it freezes the reference/owner/property contract
needed by the next bounded writer task.

## Evidence

- `npm --prefix web run test:library-override-desktop` passed.
- Blender 5.2 source/target fixture regeneration matched the normalized desktop report.
- The reference retains `m12_override_source.blend`; the local object is `LOCAL_OVERRIDE`; the only
  recorded property path is `["m12_override_value"]` with value `2.5` and one `REPLACE` operation.
- Save/reopen preserves the reference, hierarchy root, owner semantics, and property metadata.

## Next Task

`M12-03K`: expose exactly one verified override writer property.

## Rollback

Remove the override generator/checker, fixture, report, manifest, package command, and this status
entry. Restore M12-03I to pending and move the machine queue back to `M12-03J`. No parity ledger
rollback is required.
