# M12-03B Status
|

|
|
status: done
|
|
task: define source library identity, owner, read-only state, and invalidation tokens
|

## Scope
|
|
|
|
Schema 1 derives `sourceLibraryId` from a canonical source locator and source `.blend` SHA-256.
|
|
Each operation binding then fixes one source data-block, its operation-specific owner and read-only
|
|
state, source generation/revision, dependency-closure SHA-256, and a hash-derived invalidation token.
|
|
|
|
APPEND owns a writable local Main ID. LINK remains owned by the matching source library and is
|
|
fully read-only. LIBRARY_OVERRIDE owns a writable local override while retaining a read-only linked
|
|
reference and hierarchy root. This is a pure protocol task and does not mutate Blender Main.
|
|
|
|
## Evidence
|
|
|
|
- `npm --prefix web run test:library-operation-identity` passed 6/6.
|
|
- Stable source identity changes when either locator or source bytes change.
|
|
- APPEND/LINK/LIBRARY_OVERRIDE produce distinct invalidation tokens for the same source root and
|
|
reject owner substitution, read-only drift, reference substitution, unknown fields, and forgery.
|
|
- Source library/hash, generation, revision, and dependency closure drift each return
|
|
`REVISION_CONFLICT`; the unchanged state revalidates the original binding exactly.
|
|
- The one initial test expectation was corrected to the actual fail-fast exact-schema code, then
|
|
the complete suite was rerun successfully.
|
|
|

|
|
- protocol: `5371133bd98e05935cd75bab582abedec32a36559af8d212f0bc8a534ef19451`

- manifest: `f388aedb9c0901932cf90c058f2f2b83259d9797cd6b144566a25e37a348c64b`

|
## Next Task
|
|
|
|
`M12-03C`: create a desktop single-Object append fixture and record stable Object, Mesh, Material,
|
|
and Image mappings.
|
|
|
|
## Rollback
|
|
|
|
Remove the library operation identity protocol, golden, unit suite, manifest, package command, and
|
|
this status entry. Restore M12-03B to pending and the queue to M12-03B. No parity ledger rollback is
|
|
required.
