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

scope: Action Editor box selection on object:WebGapSelectBoxObject.

evidence:

Blender executes bpy.ops.action.select_box(mode="SET") over the frame-3 region coordinates; only frame 3 is selected on all channels.
Desktop and WASM/Main expose matching frames and selected flags; 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 SET mode and a frame-only box; ADD/SUB/channel-range selection remains separate behavior.
