# M16-GAP-00127 Status status: done task: action.markers_make_local operator LOCAL_EXACT slice updated: 2026-08-20 America/New_York scope: Action Editor selected scene-marker localization on `object:WebGapMarkersMakeLocalObject`. evidence: - Blender creates and selects `LocalActionMarker` at frame 3, then executes `bpy.ops.action.markers_make_local`; the marker moves into the Action. - Reader exposes Action markers; desktop and WASM/Main both read `LocalActionMarker@3`, and save/reopen is exact. - Malformed Blend input is rejected without mutating Main animation data. - Generator, rebuilt WASM, desktop checker, npm comparator, direct comparator, context handoff, and governance exit 0. knownRisk: This slice covers one selected scene marker; multiple-marker ordering and unselected marker retention remain separate cases. nextTask: `M16-GAP-00128`
