status: done
task: action.interpolation_type operator LOCAL_EXACT slice
updated: 2026-08-20 America/New_York

scope: Action Editor interpolation-type operation on `object:WebGapInterpolationTypeObject`.

evidence:

- Blender selects frame 3 in all three location channels and executes `bpy.ops.action.interpolation_type(type="LINEAR")`.
- Desktop and WASM/Main expose `BEZIER, LINEAR, BEZIER` per channel; 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 LINEAR interpolation on selected keys; other interpolation families and operators remain separate tasks.
