# Rollback V51.2

Restore the three V51.1 files from your previous V51.1 backup/package:
- `Chairman/supreme/ChairmanSupremeDecisionEngineV51.php`
- `Chairman/api/api_supreme_v51.php`
- `wr_chairman_supreme_decision_ai_v51_0.php`

No database rollback is needed because V51.2 performs no schema changes.
