M16-GAP-00184 Status

status: done task: anim.keyframe_delete_v3d operator LOCAL_EXACT slice updated: 2026-08-22 America/New_York

scope:

• The minimal fixture contains one selected/active object with a custom delete_target property and an Action keyed at frames 1, 3, and 5. A foreground VIEW_3D context invokes ANIM_OT_keyframe_delete_v3d(confirm=false) (poll=true, FINISHED) at frame 3, deleting only the current keyframe and preserving the two surrounding keys.

evidence:

• Desktop evidence records the selected/active object changing from [1, 3, 5] to [1, 5]; the custom property remains at 3.0 and save/reopen is exact.
• WASM/Main reads the same Action as one [\"delete_target\"][0] channel with three keyframes before the operation fixture and two keyframes after it. WASM save/reopen is exact, and malformed Blend input is rejected without Main mutation.
• Fixture generation, foreground VIEW_3D checker, npm comparator, direct idempotent comparator, and artifact hashing passed. No production reader or protocol change was required because the existing generic Action/F-Curve reader exposes this custom-property channel.
