## Notes

- `save_scene({ includeCurrentScene: false, graph })` should persist the graph verbatim, preserving all node ids.
- `stableStringify` normalises key order so byte equality is order-independent; this is the canonical "deep-equal" check here.
- Step 5 rebuilds the scene by save/load-ing a shell (site+building+level) then replaying every remaining node as an `apply_patch` `create` op. Only counts-per-type are compared (node ids on the rebuild will equal the originals because we reuse the same ids in the patches).
- Step 6 exercises `duplicate_level` against the copied scene; the site/building remain shared (count=1), while per-level types should double.
