# M16-GAP-00237 Status

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

scope:

- The minimal fixture contains one selected source bone with both endpoints selected and one independent unselected bone.
- Desktop runs `ARMATURE_OT_duplicate_move` in edit mode with `poll=true` and `FINISHED`, creating `WebGapArmatureDuplicateMoveSource.001` translated by `(1, 2, 3)` while preserving the source and independent bone through save/reopen.
- Main already exposes armature bone names, selection state, parent IDs, and head/tail coordinates, so the same moved duplicate is observable in WASM/Main 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 duplicate with desktop-matching translated geometry and selection, rejects malformed Blend input without Main mutation, and remains stable across save/reopen.
- Repeated checker runs recognize the already-moved state and remain idempotent; Chromium-only policy was preserved and no Firefox/WebKit run was made.
