# M16-GAP-00125 Status status: done task: action.keyframe_insert operator LOCAL_EXACT slice updated: 2026-08-20 America/New_York scope: Action Editor keyframe insertion on `object:WebGapKeyframeInsertObject`. evidence: - Blender starts with frames 1 and 5, runs `bpy.ops.action.keyframe_insert(type="ALL")` at frame 3, and produces three keys in each location channel. - Desktop and WASM/Main expose matching frames, values, and selection flags; save/reopen is exact. - Malformed Blend input is rejected without mutating Main animation data. - Generator, desktop checker, npm comparator, direct comparator, context handoff, and governance exit 0. knownRisk: This slice covers `ALL` insertion into existing Action channels; grouped/selected-channel modes remain separate behavior. nextTask: `M16-GAP-00126`
