M16-GAP-00251 Status

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

scope:

• The minimal fixture contains a selected root, an unselected connected child, and an independent unselected bone. Blender desktop runs ARMATURE_OT_select_hierarchy(direction=CHILD, extend=false), selecting the immediate connected child and making it active without changing hierarchy, visibility, or geometry.
• WASM/Main reads the same fixture, including armature-space child coordinates through arm_head/arm_tail with legacy head/tail fallback. The comparator confirms desktop/WASM parity and save/reopen stability.

evidence:

• Fixture generation, desktop checker, npm comparator, direct comparator, malformed-input negative, save/reopen check, production WASM rebuild, and task-context handoff passed.
• Repeated checker execution is idempotent (SKIPPED_ALREADY_APPLIED after the first run); Chromium-only policy was preserved and no Firefox/WebKit run was made.
