Phase Failure:
Rollback Protocol:
## Rollback Required
**Phase:** [phase number]
**Reason:** [failure description]
**Action:** Rolling back to Phase [N-1]
### Rollback Steps
1. Preserve failed artifacts (for diagnosis)
2. Restore previous phase state
3. Address failure root cause
4. Re-attempt phase
