M16-GAP-00228 Status

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

scope:

• The minimal fixture contains three bone collections, each retaining one distinct bone, with only the first bone selected and the middle collection active.
• Desktop runs ARMATURE_OT_collection_select in Edit Mode with poll=true and FINISHED, selecting the active collection's bone while preserving the other selection states and collection membership through save/reopen.
• The existing Main reader's bone selected flags, collection indices, and bone IDs provide the observable selection; 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-selected active collection and remain idempotent.
• WASM/Main observes the same selected bone IDs and collection order, preserves them across save/reopen, and rejects malformed Blend input without Main mutation.
• Chromium-only policy was preserved; no Firefox/WebKit run was made.
