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
