# M16-GAP-00164 Status status: done task: anim.channels_select_all operator LOCAL_EXACT slice updated: 2026-08-21 America/New_York scope: - Action Editor `anim.channels_select_all` selects all three F-Curve channels without selecting keyframes. evidence: - Blender desktop and WASM/Main expose the same three `location` channels with `selected: true` and unchanged keyframe selection. - The reader exposes the persisted `FCURVE_SELECTED` flag through the optional SceneIR channel field `selected`. - Save/reopen preserves the animation snapshot exactly; malformed Blend input is rejected without Main mutation. - Fixture generation, desktop checker, npm comparator, direct comparator, WebEngine rebuild, context governance, and artifact hashing passed. nextTask: `M16-GAP-00165`
