M16-GAP-00190 Status

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

scope:

• The minimal fixture contains one selected/active object with a custom active_target property, a three-key Action, and two named Keying Sets. A foreground VIEW_3D context invokes ANIM_OT_keying_set_active_set(type=WebGapAnimKeyingSetActiveB) (poll=true, FINISHED), changing the active Keying Set from A to B without changing the Action.

evidence:

• Desktop evidence records active Keying Set WebGapAnimKeyingSetActiveA changing to WebGapAnimKeyingSetActiveB; the Action remains [1, 3, 5], the property remains 3.0, and save/reopen is exact.
• WASM/Main reads the same fixture with the visible Action unchanged and save/reopen exact. The current scene snapshot does not expose Keying Set metadata, so the report explicitly records keyingSetMetadata: NOT_EXPOSED_BY_SCENE_SNAPSHOT; 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 made.
