+| 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. |

+
+### 6.2 Manifest-Schema-Dokumentation aktualisieren (3 Std)
+
+**`MANIFEST_SCHEMA_DOC` in `manifest.py` erweitern:**
+- Alle neuen Felder in `fields`-Dict aufnehmen
+- `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 |
+| 3 | `ai_ui_control` | 20 Min | author, min_app_version, contract_version |
+| 4 | `automation` | 30 Min | author, min_app_version, hooks, contract_version |
+| 5 | `calendar` | 20 Min | author, min_app_version, hooks, contract_version |
+| 6 | `dms` | 20 Min | author, min_app_version, hooks, contract_version |
+| 7 | `entity_links` | 15 Min | author, min_app_version, contract_version |
+| 8 | `forgejo_error_reporter` | 15 Min | author, min_app_version, contract_version |
+| 9 | `kommunikation` | 30 Min | author, min_app_version, hooks, contract_version |
+| 10 | `mail` | 20 Min | author, min_app_version, hooks, contract_version |
+| 11 | `mcp_client` | 20 Min | author, min_app_version, contract_version |
+| 12 | `mcp_server` | 20 Min | author, min_app_version, contract_version |
+| 13 | `permissions` | 20 Min | author, min_app_version, contract_version |
+| 14 | `report_generator` | 20 Min | author, min_app_version, contract_version |
+| 15 | `system_notif` | 15 Min | author, min_app_version, contract_version |
+| 16 | `tags` | 15 Min | author, min_app_version, contract_version |
+| 17 | `tasks` | 20 Min | author, min_app_version, hooks, contract_version |
+| 18 | `test_sample` | 10 Min | author, min_app_version, contract_version |
+| 19 | `unified_search` | 20 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

+"""Fix RLS policies on contacts — add tenant_id isolation.

+Revision ID: 0060
+Revises: 0059
+Create Date: 2026-07-29
+
+This migration drops the insecure contact RLS policies (created in 0052)
+and recreates them with proper tenant_id isolation.
+
+Problems fixed:
+1. contacts_tenant_owned_visible had USING (owner_id IS NULL) without tenant_id check
+2. contacts_admin_visible had no tenant_id check
+3. contacts_owner_visible had no tenant_id check
+4. All policies used FOR ALL instead of separate SELECT/INSERT/UPDATE/DELETE
+5. No WITH CHECK on write operations
