M16-GAP-00180 Status

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

scope:

• The minimal fixture contains one selected image strip with a Scene Action animating blend_alpha at frames 1, 3, and 5. A real foreground SEQUENCE_EDITOR context invokes ANIM_OT_keyframe_clear_vse(confirm=false) (poll=true, FINISHED), removing the selected strip's editable F-Curve while preserving the strip and its evaluated value.

evidence:

• Desktop evidence records the selected/active strip changing from three selected keyframes to no F-Curves. WASM/Main reads the same Scene Action channel before clearing and no matching animation from the cleared fixture. Save/reopen is exact and malformed Blend input is rejected without Main mutation.
• Fixture generation, foreground VSE desktop checker, npm comparator, direct comparator, and artifact hashing passed. The checker is idempotent for the already-cleared exact fixture while retaining the original before evidence.
