M16-GAP-00226 Status

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

scope:

• The minimal fixture contains three bone collections, each initially retaining one distinct bone, with the middle collection active at index 1.
• Desktop runs ARMATURE_OT_collection_remove with poll=true and FINISHED, removing the active collection, leaving its bone unassigned, and preserving the remaining collections through save/reopen.
• The existing Main reader's collection indices and bone IDs provide the observable removal; no new data-block, editor, or browser behavior was added.

evidence:

• The generator, desktop checker, npm comparator, direct comparator, and task-context checks passed. Repeated checker runs recognize the already-removed collection and remain idempotent.
• WASM/Main observes the same remaining collection order, member IDs, and unassigned removed bone, preserves them across save/reopen, and rejects malformed Blend input without Main mutation.
• Chromium-only policy was preserved; no Firefox/WebKit run was made.
