# M16-GAP-00119 Status status: done task: action.duplicate_move operator LOCAL_EXACT slice updated: 2026-08-20 America/New_York scope: Action Editor duplicate-move operation on `object:WebGapDuplicateMoveObject`. evidence: - Blender generator selects frame 3 and executes `bpy.ops.action.duplicate_move` with a time translation of +2; the duplicate lands at frame 5 and is selected in all three channels. - WASM/Main reads the same `[1, 3, 5]` channels with frame 5 selected; save/reopen is exact. - Malformed Blend input is rejected without mutating Main. - Generator, desktop checker, npm comparator, direct comparator, context handoff, and WASM-backed comparison exited 0. knownRisk: This slice covers duplicate-move with a fixed +2 frame translation; other transform modes and editor contexts remain separate operator tasks. nextTask: `M16-GAP-00120`
