+# Regles d'execution obligatoires (DP/Claude)
+
+Ces regles sont bloquantes pour toute intervention.
+
+## Interdits absolus
+
+1. **Ne PAS toucher PMTA / SSH config**
+   - Justification: incidents critiques des 20-21 janvier.
+2. **Ne PAS modifier `multiInstall.js` / JAR Java**
+   - Justification: race conditions et blocages observes.
+3. **Ne PAS remplacer des fichiers entiers**
+   - Mode obligatoire: corrections chirurgicales (`str_replace` cible, patch localise).
+
+## Obligations a chaque lot
+
+1. **GOLD backup avant modification**
+   - Exemple: `cp file file.bak-$(date +%H%M)`.
+2. **PHP syntax check apres chaque edit**
+   - Exemple: `php -l fichier.php`.
+3. **0 info confidentielle dans le code**
+   - Cibles: concurrents, clients sensibles, IPs internes, termes internes interdits.
+4. **Commit + push apres chaque lot**
+   - Objectif: zero derive, historique traçable.
+5. **Test non-regression apres chaque lot**
+   - Commande: `./nonreg-framework.sh`.
+
+## Validation DP
+
+- 0 regression
+- 0 dirty
+- aucune modification interdite
