## Evidence

- Desktop and WASM preserve the cube fixture through open and save/reopen; Main executes create, transform, undo and redo with revisions `1 -> 5`.
- Chromium production flow saves the initial revision, edits the scene, recovers the edited scene after an engine Worker fault, cancels a 40 MiB open without replacing the scene, and exports a valid GLB.
- Malformed blend input is rejected without Main mutation; cancellation cleanup reports zero live reader and engine requests.
