# Rollback V51.1

Restore these files from your previous full-project backup:

- `Chairman/supreme/ChairmanSupremeDecisionEngineV51.php`
- `Chairman/api/api_supreme_v51.php`
- `wr_chairman_supreme_decision_ai_v51_0.php`
- `analysis_chairman_v51_supreme.php`

No database rollback is required because V51.1 does not alter schema.
