# M16-GAP-00209 Status

status: done
task: anim.slot_unassign_from_id operator LOCAL_EXACT slice
updated: 2026-08-22 America/New_York

scope:

- The minimal fixture assigns `OBWebGapUnassignIdSlot` to `WebGapAnimUnassignIdObject` through `WebGapAnimUnassignIdAction` and keys one custom property.
- Desktop runs `ANIM_OT_slot_unassign_from_id` with the animated ID context. The reader preserves the Action animation and exposes the retained slot identifier plus assigned/handle state.

evidence:

- Desktop evidence records `poll=true`, `FINISHED`, `ID_SLOT_UNASSIGNED`, the nonzero-to-zero handle transition, retained `lastSlotIdentifier`, and exact save/reopen. Repeated checker runs preserve the initial evidence and fixture hash.
- WASM/Main observes `slotAssigned=false` and handle `0` with the expected keyframes, preserves it across save/reopen, and rejects malformed Blend input without Main mutation.
- The generator, npm comparator, direct comparator, WebEngine rebuild, and task-context checks passed. Chromium-only policy was preserved; no Firefox/WebKit run was made.
