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.
