+| **Phase 3** (M1-M4, M6) | `825d638` | Passwort-Komplexität (M1), Login-Response (M2), Permission-Cache (M3), ENVIRONMENT (M4), weitere (M6) | ✅ Implementiert |

+| P0-1 | Auth-Bypass via X-Internal-Call | ✅ Behoben | `app/deps.py` hat keinen X-Internal-Call Code mehr. Auth nur via Session-Cookie. |
+| P0-2 | Destruktive Migrationen | ✅ Behoben | Migration 0021 benennt Tabellen um (`*_old`). Migration 0044 repariert RLS. |
+| P0-3 | Plugin-Upload RCE | ✅ Neutralisiert | Alle Upload-Endpoints deaktiviert (403). `_extract_plugin_from_zip()` ist Dead Code. |
+| P0-4 | RLS nicht erzwungen | ✅ Behoben | Migration 0028 setzt FORCE RLS. Migration 0044 erstellt `crm_runtime` (NOSUPERUSER, NOBYPASSRLS). |
+| P0-5 | Plugin-Doppelregistrierung | ✅ Behoben | Routen nur in create_app(). require_active_plugin() prüft Aktivierungsstatus. |
+| P0-6 | Kein persistentes Volume | ✅ Behoben | docker-compose.yml hat volumes für PostgreSQL, Redis, App-Uploads, Worker. |
+| P0-7 | Öffentliche Domain | ✅ Behoben | Keine crm.media-on.de Referenz mehr in docker-compose.yml. |

+- `example`-Manifest mit neuen Feldern aktualisieren
+- API-Endpoint `GET /api/v1/plugins/manifest` liefert vollständiges Schema
+
+### 6.3 Alle 19 Plugin-Manifeste aktualisieren (8 Std)
+
+Jedes Plugin-Manifest muss um die neuen Felder erweitert werden:
+
+| # | Plugin | Aufwand | Neue Felder |
+|---|---|---|---|
+| 1 | `ai_assistant` | 30 Min | author, min_app_version, hooks, contract_version |
+| 2 | `ai_proactive` | 30 Min | author, min_app_version, hooks, contract_version |

+
+**Muster für Aktualisierung:**
+```python
+# VORHER:
+manifest = PluginManifest(
+    name="calendar",
+    version="1.0.0",
+    display_name="Calendar",
+    ...
+)
+
+# NACHHER:
+manifest = PluginManifest(
+    name="calendar",
+    version="1.0.0",
+    display_name="Calendar",
+    # ... bestehende Felder ...
+    # ── Neue Felder ──
+    min_app_version="1.0.0",
+    author="LeoCRM Team",
+    license="MIT",
+    hooks=["calendar.before_appointment", "calendar.after_appointment"],
+    contract_version="1.0.0",
+)
+```
+
+### 6.4 Frontend Plugin-Manifest-Typen aktualisieren (2 Std)
+
+**`frontend/src/api/pluginManifests.ts` und `frontend/src/types/automation.ts`:**
+- TypeScript-Interfaces um neue Manifest-Felder erweitern
+- `PluginManifestResponse`-Typ aktualisieren
+- Frontend-Komponenten die Manifest-Felder anzeigen erweitern
+
+### 6.5 Manifest-Validierung verschärfen (3 Std)
+
+**Neue Validierungsregeln in `PluginManifest`:**
+```python
+@field_validator("min_app_version")
+@classmethod
+def validate_min_app_version(cls, v: str) -> str:
+    """Validate SemVer format."""
+    from app.plugins.semver import SemVer
+    SemVer.parse(v)  # Raises ValueError if invalid
+    return v
+
+@field_validator("hooks")
+@classmethod
+def validate_hooks(cls, v: list[str]) -> list[str]:
+    """Validate hook names follow namespace.pattern."""
+    for hook in v:
+        if not re.match(r"^[a-z_]+\.[a-z_]+$", hook):
+            raise ValueError(f"Invalid hook name '{hook}': must be 'namespace.action'")
+    return v
+```
+
+### 6.6 Tests für erweitertes Manifest (3 Std)
+
+- `test_manifest.py` — Neue Felder validieren
+- `test_manifest_validation.py` — SemVer-Validierung, Hook-Name-Validierung
+- Alle Plugin-Tests: Manifest mit neuen Feldern erstellen
+- Frontend-Tests: Manifest mit neuen Feldern rendern
+
+### Meilenstein Phase 6:
+- ✅ `PluginManifest` hat alle neuen Felder (min_app_version, author, hooks, contract_version, etc.)
+- ✅ `MANIFEST_SCHEMA_DOC` ist vollständig aktualisiert
+- ✅ Alle 19 Plugin-Manifeste haben die neuen Felder
+- ✅ Frontend-Typen sind aktualisiert
+- ✅ Manifest-Validierung ist verschärft
+- ✅ Tests bestanden

+
+# Nur Worker
+COOLIFY_API_TOKEN=<token> python scripts/deploy.py --worker-only
+```
+
+---
+
+## Was erledigt ist
+
+### Phase 0+1 (Security & RLS)
+- 5 DB-Rollen mit separaten Verbindungen
+- RLS fail-closed auf 108 Tenant-Tabellen
+- FORCE ROW LEVEL SECURITY aktiviert
+- 0 legacy app.tenant_id Policies
+- Plugin-Migrationen über crm_migration (DDL)
+- Worker per-Tenant Outbox-Processing mit RLS-Kontext
+- Event-Handler nur für aktive Plugins
+- Passwort-Reset end-to-end mit SMTP getestet
+- Leere DB-Installation ohne manuelle Eingriffe
+- Restore + Upgrade verifiziert
+- Coolify Redeploy/Stop/Start funktioniert ohne manuelles Eingreifen
+
+### Phase 2 (Datenintegrität)
+- 74 FK-Constraints (tenant_id → tenants.id ON DELETE CASCADE) hinzugefügt
+- 10 globale Tabellen ausgeschlossen
+- Orphan-Cleanup durchgeführt
+- FK-Tests auf Produktion: INSERT mit ungültiger tenant_id blockiert ✅
+
+### Phase 3 (Plugin-Lifecycle)
+- 14 Tests: Registry, Lifecycle, Idempotency, Dependencies, Core-Schutz
+- Plugin-Lifecycle war bereits korrekt implementiert
+- Tests bestätigen: activate → deactivate → reactivate funktioniert
+
+---
+
+## Was als nächstes zu tun ist
+
+### Phase 5 (Outbox) — abgeschlossen (produktionsverifiziert)
+- Per-Tenant Outbox-Processing (Gate 5)
+- Dead-Letter-Queue: error_message + failed_at Spalten, Replay-Funktionen
+- Monitoring: /api/v1/outbox/stats, /failed, /consumer-registry Endpoints
+- Consumer-Registry: outbox_deliveries pro Consumer-Handler geschrieben
+- Processing-Recovery: recover_stuck_events (stuck processing -> pending)
+- Retention-Cleanup: cleanup_published_events (hourly cron job, 30 days)
+- Replay setzt outbox_deliveries zurueck (clean retry)
+- 23/23 Unit-Tests + Produktions-Verifikation:
+  - outbox_deliveries: 4 Eintraege mit status=delivered
+  - recover-stuck: 200, 0 stuck events
+  - cleanup-published: 200, 22 alte Events geloescht
+  - consumer-registry: 200, alle Handler gelistet
+  - failed: 200, 0 failed events
+  - stats: 200, korrekte counts
+- deploy.py repariert: Worker-Deploy funktioniert jetzt korrekt
+
+### Phase 7 (DMS/Attachments) — nicht begonnen
+- Streaming Upload/Download
+- Deduplikation tenantlokal
+- Keine Cross-Tenant-Dateireferenzen
+- Aufwand: 10–16h
+
+### Phase 4 (KI-Delegation) — nicht begonnen
+- Delegation-Contract, Tenant-scoped Permissions
+- Audit, Rollback, Approval
+- Aufwand: 10–16h
+
+### Phase 6 (Workspaces) — abgeschlossen (produktionsverifiziert)
+- Backend: Widget CRUD (create, list, update, delete), Manager-Role-Check, Cross-Tenant-Validierung
+- Default-Workspace Seeding (12 Standard-Module), Set-User-Default-Workspace
+- Fix: create_workspace Default-Uniqueness (unset others before insert)
+- Frontend: workspaceStore (Zustand) mit sessionStorage Persistenz
+- API-Client Interceptor: X-Workspace-ID Header auf allen Requests
+- useWorkspace hook auf workspaceStore umgestellt
+- Widget API hooks: useWorkspaceWidgets, useCreateWorkspaceWidget, etc.
+- Settings-Route: /settings/workspaces mit WorkspaceManagerPage
+- 25 Backend-Tests + 12 Frontend-Tests (alle bestanden)
+- Produktions-Verifikation:
+  - 2 Workspaces (Verkauf/Einkauf) mit unterschiedlichen Modulen ✅
+  - Hidden module (calendar in Einkauf) nicht in Context ✅
+  - Multiple widgets mit gleichem key (2x recent_contacts) ✅
+  - Widget CRUD: create, update, delete ✅
+  - Set-default: Workspace-Wechsel funktioniert ✅
+  - Manager-Role: Creator ist Manager ✅
+  - Cross-Tenant: RLS isoliert Workspaces pro Tenant ✅
+
+### Phase 8–10 — nicht begonnen
+- Sicherheitsreste, CI, Backup/Monitoring
+- Aufwand: 38–66h

+## Wichtige Regeln für den nächsten Agenten
+
+1. **Keine manuellen Docker-Befehle** — alles über Coolify API oder deploy.py
+2. **Repo lesen bevor ändern** — docker-compose.yml und deploy.py beachten
+3. **Migrationen sind Forward-Only** — keine alten Migrationen verändern
+4. **RLS ist fail-closed** — kein Tenant-Kontext = kein Zugriff
+5. **crm_api hat keine DDL-Rechte** — Plugin-Migrationen über get_migration_engine()
+6. **Worker ist Coolify Service** — UUID asxqaq3566to108xordck0ff
+7. **Alle DB-Passwörter sind identisch** — siehe .env.docker.example
+8. **pgvector/pgvector:pg16** als DB-Image — nicht postgres:16-alpine
+9. **Tests müssen mit echten unprivilegierten Rollen laufen** — nicht mit Superuser
+10. **Jede Phase: analysieren → implementieren → migrieren → testen → dokumentieren**

+4. All policies used FOR ALL instead of separate SELECT/INSERT/UPDATE/DELETE
