M16-GAP-00263 Status

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

scope:

• The fixture contains one selected positive-X WebGapArmatureSymmetrizeSource.L bone and one unrelated unselected bone. Blender desktop runs ARMATURE_OT_symmetrize(direction="NEGATIVE_X"), producing the mirrored WebGapArmatureSymmetrizeSource.R bone and preserving the result through save/reopen.
• WASM/Main reads the same armature. The comparator confirms mirrored geometry, selection state, malformed-input rejection without Main mutation, and save/reopen.

evidence:

• Fixture generation, desktop checker, npm comparator, and direct comparator passed with exit code 0. Chromium-only policy was preserved and no Firefox/WebKit run was made.
