# M16-GAP-00132 Status status: done task: action.push_down operator LOCAL_EXACT slice updated: 2026-08-20 America/New_York scope: Action Editor push-down into NLA on `object:WebGapPushDownObject`. evidence: - Blender executes `bpy.ops.action.push_down`; active Action is removed from the active slot and moved to one NLA track with one strip. - Desktop and WASM/Main expose the original Action and matching NLA strip/action identity; save/reopen is exact. - Malformed Blend input is rejected without mutating Main animation/NLA state. - Generator, desktop checker, npm comparator, direct comparator, context handoff, and governance exit 0. knownRisk: This slice covers one push-down operation into an empty NLA stack; existing-track blending remains separate behavior. nextTask: `M16-GAP-00133`
