## Evidence

- Blender desktop retains the external `WBV2P3005Library.blend` ownership and linked object as read-only; the source library contains the declared append Object/Mesh/Material/Image closure with a packed image. Desktop save/reopen is exact.
- WASM/Main exposes the missing external library as `EXTERNAL_REQUIRED` without importing unavailable linked data, then appends the declared closure as local Main data in one revision. The appended packed image remains local and exact after save/reopen.
- Library operation identity validates APPEND, LINK, and LOCAL_OVERRIDE ownership. Override freshness, linked reload, and missing-library transitions accept current generations and reject stale revision/hash inputs; stale append and closure collision do not change Main revision; malformed input does not mutate Main.
