+# Contrôle du scope — Anti-scope-creep
+
+**Objectif** : Éviter toute dérive de scope. Chaque modification doit être intentionnelle et traçable.  
+**Référence active** : [V0_102_RELEASE_SCOPE.md](V0_102_RELEASE_SCOPE.md)  
+**Version précédente** : [V0_101_RELEASE_SCOPE.md](V0_101_RELEASE_SCOPE.md)
+
+---
+
+## 1. Règle d'or
+
+> **Avant d'ajouter quoi que ce soit : vérifier si c'est dans le scope v0.101.**  
+> Si non → ne pas ajouter. Créer un ticket pour une version ultérieure.
+
+---
+
+## 2. Pendant la phase v0.101 (jusqu'au tag)
+
+### 2.1 Autorisé
+
+- **Corrections de bugs** sur les features IN SCOPE
+- **Stabilisation** : tests, refactoring sans changement de comportement
+- **Nettoyage** : suppression de code mort, consolidation
+- **Documentation** : mise à jour des docs existantes
+- **Sécurité** : correctifs de vulnérabilités identifiées
+- **Accessibilité** : corrections a11y sur composants existants
+
+### 2.2 Interdit
+
+- **Nouvelles features** (même "petites")
+- **Nouvelles routes** ou pages
+- **Nouvelles dépendances** (sauf correctif sécurité)
+- **Changements de comportement** sur les features HORS SCOPE
+- **"Améliorations"** non liées à un bug identifié
+
+### 2.3 Cas limite
+
+| Situation | Action |
+|-----------|--------|
+| Bug dans une feature HORS SCOPE | Corriger si blocant pour une feature IN SCOPE. Sinon : ticket pour plus tard. |
+| Dépendance obsolète/vulnérable | Mettre à jour. Documenter dans la PR. |
+| Refactoring qui change une API interne | Autorisé si 0 impact sur le contrat public et tests passent. |
+| "Petite amélioration UX" | **Non.** Créer un ticket pour v0.102+. |
+
+---
+
+## 3. Processus de validation avant commit
+
+### 3.1 Checklist pré-commit (dans la tête)
+
+1. **Mon changement modifie-t-il une feature IN SCOPE ?**
+   - Oui → Continuer. S'assurer qu'il n'y a pas de régression.
+   - Non → **STOP.** Est-ce une correction de bug ? Si oui, la feature est-elle IN SCOPE ?
+
+2. **Mon changement ajoute-t-il du code ?**
+   - Nouvelle route, nouveau composant, nouveau service → **STOP.** Hors scope v0.101.
+   - Correction, refactoring, test → OK si lié à une feature IN SCOPE.
+
+3. **Mes tests passent-ils ?**
+   - `npm test -- --run` (frontend)
+   - `go test ./...` (backend)
+   - Aucune régression sur les tests existants.
+
+### 3.2 Conventions de commit
+
+Format : `type(scope): description`
+
+- `fix(auth): correct token refresh loop` ✅
+- `fix(playlists): pagination boundary check` ✅
+- `test(player): add coverage for seek` ✅
+- `refactor(tracks): extract upload validation` ✅
+- `feat(chat): add typing indicator` ❌ (nouvelle feature)
+- `chore: update deps` → OK si correctif sécurité, sinon éviter
+
+**Commits réguliers** : 1 commit = 1 changement logique. Pas de méga-commits.
+
+---
+
+## 4. Processus PR
+
+### 4.1 Vérification scope (obligatoire)
+
+Dans chaque PR, le relecteur doit valider :
+
+- [ ] Le changement est dans le scope v0.101 (voir [V0_101_RELEASE_SCOPE.md](V0_101_RELEASE_SCOPE.md))
+- [ ] Aucune nouvelle feature ajoutée
+- [ ] Aucune régression sur les flows critiques
+- [ ] Les tests passent
+- [ ] La description explique le *pourquoi* (bug, stabilisation, nettoyage)
+
+### 4.2 Rejet automatique
+
+Une PR sera rejetée si :
+
+- Elle ajoute une nouvelle route, page ou feature
+- Elle modifie le comportement d'une feature HORS SCOPE (sauf correctif bug critique)
+- Les tests échouent
+- Elle introduit une dépendance non justifiée
+
+---
+
+## 5. Proposer une feature pour APRÈS v0.101
+
+### 5.1 Template
+
+Utiliser le template [Feature request](.github/ISSUE_TEMPLATE/feature_request.md) avec :
+
+- **Alignement scope** : cocher "Hors scope v0.101 — pour v0.102+"
+- **Justification** : pourquoi cette feature est nécessaire
+- **Effort estimé** : S / M / L / XL
+- **Dépendances** : quelles features v0.101 doivent être stables avant
+
+### 5.2 Workflow
+
+1. Créer une issue avec le template
+2. **Ne pas implémenter** tant que v0.101 n'est pas taguée
+3. Une fois v0.101 stable, prioriser les issues "v0.102" dans un nouveau document de scope
+
+---
+
+## 6. Gestion des exceptions
+
+### 6.1 Urgence sécurité
+
+Si une vulnérabilité critique est identifiée :
+
+- Correctif autorisé **immédiatement**
+- Documenter dans la PR
+- Pas besoin d'être dans le scope v0.101
+
+### 6.2 Blocage production
+
+Si un bug bloque un déploiement ou un flow critique :
+
+- Correctif autorisé
+- La feature concernée doit être IN SCOPE ou dépendance directe d'une feature IN SCOPE
+
+### 6.3 Décision collégiale
+
+Pour tout cas ambigu :
+
+- Ouvrir une issue "Scope clarification"
+- Décision documentée dans l'issue
+- Mise à jour de V0_101_RELEASE_SCOPE.md si le scope est étendu (exception rare)
+
+---
+
+## 7. Après le tag d'une version
+
+1. **Créer** le document de scope de la version suivante (ex: `V0_103_RELEASE_SCOPE.md`)
+2. **Définir** explicitement les nouvelles features autorisées
+3. **Mettre à jour** la référence active dans ce document (section header)
+4. **Reprendre** ce processus avec le nouveau document de scope
+5. **Archiver** l'ancien document dans `docs/archive/` une fois obsolète
+
+**Historique des versions** :
+- v0.101 : Stabilisation, freeze fonctionnel (taguée)
+- v0.102 : Déblocage Coming Soon, renforcement coeur produit (en cours)
+- v0.103 : Complétion Phase 1 Fondation (à venir)
+
+---
+
+## 8. Rappel pour les contributeurs
+
+- **Cursor / IA** : Les règles dans `.cursorrules` rappellent de vérifier le scope avant toute modification.
+- **Humains** : Lire [V0_101_RELEASE_SCOPE.md](V0_101_RELEASE_SCOPE.md) avant de coder.
+- **En doute ?** Ouvrir une issue "Scope clarification" plutôt que de coder.

+### Tests internal/testutils et SetupTestDB()
+
+Les tests dans `internal/testutils` qui utilisent `SetupTestDB()` (db_cleanup_test, db_test, fixtures_test) nécessitent Docker et testcontainers (PostgreSQL). En l'absence de Docker ou avec `-short`:
+- Ces tests sont automatiquement skippés via `SkipIfDockerUnavailable(t)`
+- Pour exécuter tous les tests sans Docker: `go test ./... -short` (les tests testutils seront skippés)
+- Pour exécuter les tests testutils: s'assurer que Docker est démarré et ne pas utiliser `-short`
