# WBV2-P1-004 Status
status: done
task: WBV2-P1-004
gate: G1
updated: 2026-08-25 America/New_York
The worker lifecycle fixture exposes a bounded cancellation/restart/dispose
contract through the Blender Text datablock and the WASM SceneIR reader.
Desktop and WASM agree that cancelled opens publish no result, stale results
from generation 1 are rejected after restart to generation 2, and CPU/WASM/GPU
owner counters return to zero after cancel, restart, and dispose. The future
extension field and schema hash survive a compressed save/reopen cycle.
Acceptance evidence:
- fixture generator exit: 0
- desktop lifecycle contract read and save/reopen exit: 0
- `npm --prefix web run test:generated-gap -- --task WBV2-P1-004` exit: 0
- `node tools/web/check-generated-gap.mjs --task WBV2-P1-004` exit: 0
- malformed blend keeps the original Main snapshot unchanged
- hash drift, cancellation, generation mismatch, and double-dispose outcomes
are represented in the bounded lifecycle receipt
