G-Diffuser 1.2.2 - Save and Import Hotfix
- Fix disk-write ownership checks that could prevent Course Edit saves from completing and cause track imports to fail with MFS error 244.
- Preserve snapshot validation, rollback, and recovery protections during save and import operations.
- Add regression coverage using the production disk-write helper, including write failures and rollback.
Back up your installation's save and course-state files before updating. This hotfix does not change the course snapshot format.
