M16-GAP-00240 Status

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

scope:

• The minimal fixture contains one source bone with its tail selected and one independent unselected bone.
• Desktop runs ARMATURE_OT_extrude(forked=true) in edit mode with poll=true and FINISHED, creating WebGapArmatureExtrudeForkedSource.001 from the source tail with connected=false while preserving the source and independent bone through save/reopen.
• Main exposes the forked bone name, parent ID, selection state, connected flag, and parent-relative head/tail coordinates; the comparator normalizes desktop armature-space coordinates against the source tail without expanding other data-blocks, editors, or browsers.

evidence:

• The generator, desktop checker, npm comparator, direct comparator, malformed-input negative, save/reopen check, and task-context checks passed.
• WASM/Main observes the forked bone with desktop-matching normalized geometry and selection, rejects malformed Blend input without Main mutation, and remains stable across save/reopen.
• Repeated checker runs recognize the already-forked state and remain idempotent; Chromium-only policy was preserved and no Firefox/WebKit run was made.
