M12-03I Status

status: done task: missing library preserves placeholder and original source reference updated: 2026-08-17 America/New_York enablingTask: false parityStateChange: false

Scope

Schema-1 missing-library requests match a linked source library by source identity, generation, and revision. Marking a matching reference missing changes only its status and adds a MISSING_LIBRARY placeholder. The original locator, source SHA-256, generation, revision, and every data-block ID remain attached to the reference; unrelated libraries remain unchanged.

Stale generation/revision and source hash drift return a stable conflict without deleting or replacing the reference. Malformed fields, duplicate identities, and inconsistent placeholder data fail closed.

Evidence

npm --prefix web run test:library-linked-missing passed 4/4 unit tests.
The matching case preserves original source metadata and data-block IDs while publishing only the placeholder status transition.
Stale, source-drift, undeclared-field, duplicate-identity, and invalid-placeholder cases publish no partial state.
