# M16-GAP-00169 Status

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

scope:

- Action Editor `anim.channels_setting_toggle(type=PROTECT)` toggles protection on all three selected F-Curve channels.

evidence:

- Blender desktop and WASM/Main expose the same three animation channels with `editable: false` after the toggle.
- The existing reader mapping of the persisted F-Curve protection flag is sufficient for this setting.
- Save/reopen preserves the animation snapshot exactly; malformed Blend input is rejected without Main mutation.
- Fixture generation, desktop checker, npm comparator, direct comparator, and artifact hashing passed.
