 ## 5. Offline Sync Protocol
 To prevent data loss in basements or unstable networks:
 - **Offline Engine:** Service Workers cache assets. IndexedDB saves data.
 - **UUID Labeling:** Every sync operation generated offline is tagged with a client-side UUID.
 - **Idempotent Backend:** The `bulk_sync` endpoint checks UUIDs against `AuditLog` before applying increments, preventing double-counts.

+- **`scripts/save_version.py`**: Implements the `save-version` AI Command Shortcut. Increments `VERSION.json` patch version, commits all staged changes, creates a snapshot branch `v.X.Y.Z`, and calls `./export_prod.sh` to generate the production bundle. Always stays on the `dev` branch.
