M16-GAP-00258 Status

status: done task: armature.separate operator LOCAL_EXACT slice updated: 2026-08-23 America/New_York

scope:

• The minimal fixture contains one selected bone and one unselected bone in a single armature. Blender desktop runs ARMATURE_OT_separate, producing an original armature with the retained bone and a separated armature with the selected bone, stable through save/reopen.
• WASM/Main reads both armature data-blocks from the same fixture. The comparator confirms desktop/WASM partition parity, malformed-input rejection without Main mutation, and save/reopen stability.

evidence:

• Fixture generation, desktop checker, npm comparator, direct comparator, and repeated checker execution passed. The second checker run is idempotent (SKIPPED_ALREADY_APPLIED); Chromium-only policy was preserved and no Firefox/WebKit run was made.
