M16-GAP-00196 Status

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

scope:

• The minimal fixture contains one selected/active object with a three-key Action and no scene Keying Set. A real PROPERTIES RNA button invokes ANIM_OT_keyingset_button_add() (poll=true, FINISHED), creating ButtonKeyingSet and adding the active button_target path.

evidence:

• Desktop evidence records Keying Set count 0→1, path count 0→1, exact path fields, unchanged [1, 3, 5] Action data, and exact save/reopen.
• WASM/Main reads the same post-operation fixture with the visible Action unchanged and save/reopen exact. The current scene snapshot does not expose Keying Set metadata, so the report records keyingSetMetadata: NOT_EXPOSED_BY_SCENE_SNAPSHOT; malformed Blend input is rejected without Main mutation.
• Fixture generation, foreground Chromium-scope desktop UI checker, npm comparator, direct idempotent comparator, and artifact hashing passed. No production reader or protocol change was made.
