M16-GAP-00220 Status

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

scope:

• The minimal fixture contains one selected armature bone from (0, 0, 0) to (0, 2, 0) and a fixed cursor at (1.5, 2.0, 1.0).
• Desktop runs ARMATURE_OT_click_extrude with poll=true and FINISHED, creating a connected .001 child whose armature-space tail reaches the cursor and preserving it through save/reopen.
• The existing Main reader exposes the parent relationship, raw child coordinates, and rest matrix; the comparator derives the same armature-space endpoint without changing unrelated armature fields.

evidence:

• The generator, desktop checker, npm comparator, direct comparator, and task-context checks passed. Repeated checker runs recognize the persisted child and remain idempotent.
• WASM/Main observes the same two-bone hierarchy, preserves it across save/reopen, and rejects malformed Blend input without Main mutation.
• Chromium-only policy was preserved; no Firefox/WebKit run was made.
