# M16-GAP-00257 Status

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

scope:

- The minimal fixture contains an active selected length-1 bone, an unselected
  length-1 peer, and an unselected length-2 bone. Blender desktop runs
  `ARMATURE_OT_select_similar(type=LENGTH, threshold=0.1)` and preserves the
  expected selection and geometry through save/reopen.
- WASM/Main reads the same fixture. The comparator confirms desktop/WASM parity,
  malformed-input rejection without Main mutation, and save/reopen stability.

evidence:

- Fixture generation, desktop checker, npm comparator, direct comparator, and
  repeated checker execution passed. The second checker run is idempotent
  (`SKIPPED_ALREADY_APPLIED`); Chromium-only policy was preserved and no
  Firefox/WebKit run was made.
