task: create a desktop linked Object fixture preserving source-library ownership

## Scope
|
|
|
|
Blender 5.2 creates a source library containing one Object with a Mesh, Material, and packed Image
|
|
dependency closure. A clean target links only the selected Object with `bpy.data.libraries.load(link=True)`.
|
|
The Object, Mesh, Material, and Image retain the source library pointer, have no library override,
|
|
and map to read-only `SOURCE_LIBRARY` ownership. The target is saved, reopened in a new Main load,
|
|
and compared to the pre-save linked graph.
|
|
|
|
This task freezes the desktop LINK contract only. It does not implement a WASM link writer, linked
|
|
mutation, reload/relocate, missing-library placeholders, or full N-023 parity.
|
|
|
|
## Evidence
|
|
|
|
- `npm --prefix web run test:library-link-desktop` passed the manifest/artifact hash gate, Blender
|
|
5.2 generator rerun, and canonical report comparison.
|
|
- The fixture links one root and four dependency IDs. All three dependency edges, 4 vertices, 4
|
|
edges, 1 polygon, 4 loops, `UVMap`, material slot, packed 2x2 sRGB RGBA image, and Float32 pixel
|
|
SHA-256 `6f0f8c231d65149e69e6ed12d370bcfa095ef90adc202065492ea8c8ef17e45a` survive save/reopen.
|
|
- Every linked ID reports `library=m12_link_source.blend` and `isLibraryOverride=false`; all four
|
|
stable mappings are `SOURCE_LIBRARY/readOnly=true`. A temporary source/target regeneration matches
|
|
the canonical report after normalizing only session-bound blend container hashes.
|
|
|
|
## Artifact Hashes

|
## Next Task
|
|
|
|
`M12-03G`: linked data writers must fail closed with `LINKED_DATA_MUTATION_BLOCKED`.
|
|
|
|
## Rollback
|
|
|
|
Remove the M12-03F link generator/checker, source and target fixtures, desktop report/manifest,
|
|
package command, and this status entry. Restore M12-03E to pending and move the machine queue back
|
|
to `M12-03E`. No parity ledger rollback is required.
