### Safety

The release explicitly keeps disabled:

- automatic go-live;
- automatic rollback;
- automatic task/review approval;
- automatic patient messaging;
- automatic clinical decisions;
- automatic signing;
- automatic OR stage changes;
- Digital Twin automatic apply.

### Important boundary

Installing 2.5.0 does not mean that UAT, regulatory classification, DPIA, restore drill, pilot, clinical sign-off or go-live has been completed. The programme records and gates those activities; real people must execute and approve them with evidence.
