+Claude Opus 4.5 (claude-opus-4-5-20251101)
 
 ### Debug Log References
 
+- Pivot table naming: Laravel attend `project_skill` (ordre alphabétique), mais la story spécifie `skill_project`. Résolu en ajoutant le nom de table explicite dans les relations `belongsToMany`.
+- Connexion MySQL: `DB_PASSWORD=` (vide) requis pour root@localhost sur Laragon.
+
 ### Completion Notes List
 
+- 4 migrations créées et fonctionnelles (translations, projects, skills, skill_project)
+- 3 models Eloquent avec relations belongsToMany, scopes et casts
+- 4 seeders de test: 37 traductions FR + 37 EN, 10 skills, 3 projets, 12 liens skill_project
+- `migrate:fresh --seed` fonctionne sans erreur
+- Relations vérifiées: Project->skills (5), Skill->projects (2)
+- Traductions vérifiées: FR, EN et fallback fonctionnent
+- Scopes vérifiés: featured (2), byCategory Frontend (4), Backend (3)
