## Evidence

- Blender desktop and WASM/Main expose the same single-user Sculpt mesh with five vertices, five faces, `.sculpt_mask`, and `.sculpt_face_set`, plus an available three-point Bezier Curve and three-point Point Cloud.
- `setSculptMeshAttributes` and a bounded `DRAW` Sculpt stroke commit atomically. The updated mask and face sets, stroke result, Curve, and Point Cloud survive save/reopen exactly.
- Unsupported brush input and malformed attribute lengths are rejected without a revision change. The PBVH query returns the stable `PAINT_PBVH_UNAVAILABLE` gate for the current WASM build; stale PBVH requests return `REVISION_CONFLICT`.
