M16-GAP-00178 Status

status: done task: anim.keyframe_clear_button operator LOCAL_EXACT slice updated: 2026-08-21 America/New_York

scope:

• The minimal fixture animates one scalar custom RNA property, clear_target, on WebGapAnimKeyframeClearButtonObject at frames 1, 3, and 5. A foreground Properties context activates that RNA button and invokes ANIM_OT_keyframe_clear_button(all=true) (poll=true, FINISHED), leaving the Action with no F-Curves.

evidence:

• Desktop evidence records the property changing from three selected keyframes to none; WASM/Main reads the original channel as ["clear_target"][0] and the cleared fixture with no matching animation. Save/reopen is exact and malformed Blend input is rejected without Main mutation.
• Fixture generation, foreground desktop checker, npm comparator, direct comparator, and artifact hashing passed. The checker and comparator are idempotent for the already-cleared exact fixture while retaining the original before evidence.
