# M16-GAP-00224 Status

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

scope:

- The minimal fixture contains two bones in separate bone collections, both initially selected, with the active collection at index 0.
- Desktop runs `ARMATURE_OT_collection_deselect` with `poll=true` and `FINISHED`, deselecting only the active collection bone while retaining the other selection through save/reopen.
- Main now exposes the persisted armature bone `selected` bit alongside the existing bone collection membership data; no other data-block, editor, or browser behavior was added.

evidence:

- The generator, desktop checker, npm comparator, direct comparator, Web Engine rebuild, and task-context checks passed. Repeated checker runs recognize the already-deselected fixture and remain idempotent.
- WASM/Main observes the same selected states, preserves them across save/reopen, and rejects malformed Blend input without Main mutation.
- Chromium-only policy was preserved; no Firefox/WebKit run was made.
