+# LeoCRM Security & Data Risk Assessment
+
+**Date:** 2026-07-26
+**Assessor:** Security Data Engineer (A0 Orchestrator)
+**Project:** LeoCRM at `/a0/usr/workdir/leocrm-fix`

+## Summary
+
+| Severity | Count |
+|----------|-------|
+| CRITICAL | 5     |

+| MEDIUM   | 8     |
+| LOW      | 5     |
+| **Total**| **26**|
+
+---
+
+## CRITICAL Issues
+
+### C-1: Redis Default Password `changeme` in docker-compose.yml
+**File:** `docker-compose.yml:53`
+**Risk:** Redis stores session data, CSRF tokens, and rate-limit counters. The default password `changeme` is trivially guessable. If Redis port 6379 is exposed, an attacker can read/modify all sessions, steal CSRF tokens, and bypass rate limits.
+**Remediation:** Remove the default fallback. Require `REDIS_PASSWORD` as a mandatory variable (`${REDIS_PASSWORD:?REDIS_PASSWORD is required}`). Use a strong randomly generated password in production.
+
+### C-2: No SECRET_KEY in `.env` — Insecure Default Active in Development
+**File:** `.env` (missing `SECRET_KEY`), `app/config.py:55`
+**Risk:** `.env` has no `SECRET_KEY`. The config defaults to `"change-me-in-production-use-a-secure-random-string"`. While `get_settings()` raises in production mode, `.env` sets `ENVIRONMENT=development`, so the default key is silently used. Any signing/token operation using `secret_key` is compromised.
+**Remediation:** Add a strong random `SECRET_KEY` (min 32 chars) to `.env`. Fail-fast in all environments if the default key is detected, not just production.
+
+### C-3: PostgreSQL and Redis Ports Exposed to Host
+**File:** `docker-compose.yml:37-38, 56-57`
+**Risk:** `ports: "5432:5432"` and `ports: "6379:6379"` expose the database and Redis to the host network. Combined with weak/default credentials, this allows direct external access to all session data and the entire database.
+**Remediation:** Remove port mappings for production. Use Docker internal networking only (`crm-net`). If debug access is needed, bind to `127.0.0.1:5432:5432` and document it as dev-only.
+
+### C-4: Unauthenticated Error Endpoint Forwards Data to External Forgejo
+**File:** `app/routes/errors.py:54-90`, `app/plugins/builtins/forgejo_error_reporter/service.py:151-250`
+**Risk:** The `/api/v1/errors` endpoint requires no authentication. CSRF middleware explicitly bypasses token checks for this path (line 48 of `middleware.py`). Any unauthenticated attacker can POST arbitrary error data (message, stack, URL, userAgent, and **arbitrary context dict**) which gets forwarded to an external Forgejo instance as a public issue. The `context` field accepts `dict[str, Any]` with no size limit on individual keys — an attacker can exfiltrate data or inject malicious content into Forgejo issues.
+**Remediation:** Require authentication for error reporting. If unauthenticated errors are needed, strip the `context` field entirely, add strict schema validation with size limits on all fields, and add a CAPTCHA or stricter rate limiting.
+
+### C-5: Plaintext Database Password in `.env`
+**File:** `.env:1`
+**Risk:** `DATABASE_URL=postgresql+asyncpg://leocrm:leocrm@localhost:5432/leocrm` embeds the DB password `leocrm` in plaintext. While `.gitignore` covers `.env`, the password is weak and identical to the username. If the file is accessed via any path traversal, backup leak, or container escape, the database is fully compromised.
+**Remediation:** Use a strong unique password. Separate `DATABASE_URL` construction from credential storage where possible (e.g., use individual `POSTGRES_USER`, `POSTGRES_PASSWORD`, `POSTGRES_HOST`, `POSTGRES_DB` env vars and construct the URL in code).
+
+---
+
+## HIGH Issues
+
+### H-1: Rate Limiter Trusts X-Forwarded-For Without Validation
+**File:** `app/core/rate_limit.py:43-45`
+**Risk:** `get_client_ip()` blindly trusts the `X-Forwarded-For` header. An attacker can set arbitrary values to bypass rate limits on login, password reset, and other endpoints. Each request with a different spoofed IP creates a new rate-limit counter.
+**Remediation:** Only trust `X-Forwarded-For` from known proxy IPs. Configure a trusted proxy list and validate the header chain. Use Starlette's `ProxyHeadersMiddleware` or validate against a `TRUSTED_PROXIES` env var.
+
+### H-2: Duplicate `get_redis()` Functions — Connection Leak
+**File:** `app/core/auth.py:53-66` and `app/core/auth.py:94-96`
+**Risk:** Two `get_redis()` functions exist. The first (line 53) returns a singleton. The second (line 94) creates a **new Redis connection on every call**. Code importing `get_redis` may use either version. The middleware (line 69) creates its own Redis connection per request. This leads to connection pool exhaustion under load.
+**Remediation:** Remove the second `get_redis()` (line 94-96). Ensure all code uses the singleton version. The middleware should use `get_redis()` from `app.core.auth` instead of creating its own connection.
+
+### H-3: CSRF Middleware Creates New Redis Connection Per Request
+**File:** `app/core/middleware.py:69-90`
+**Risk:** For every unsafe HTTP request, the middleware creates a new `aioredis.from_url()` connection, uses it, then closes it. Under load, this creates thousands of connections and can exhaust Redis connection limits.
+**Remediation:** Use the global Redis singleton via `from app.core.auth import get_redis`. Remove the per-request connection creation and the `finally: await redis.close()` block.
+
+### H-4: CSRF Token Stored Plaintext in PostgreSQL
+**File:** `app/core/auth.py:141` (`SessionModel` stores `csrf_token`)
+**Risk:** The CSRF token is stored as plaintext in the PostgreSQL `sessions` table (audit trail). If the database is compromised, all active CSRF tokens are available for CSRF attacks.
+**Remediation:** Store only a hash of the CSRF token in PostgreSQL (like `hash_token()` already exists for session tokens). Compare hashes during validation.
+
+### H-5: No File Upload Validation in Storage Backend
+**File:** `app/core/storage.py:69-128`
+**Risk:** `LocalStorage` performs no validation on uploaded files:
+- No path traversal protection: `os.path.join(self.base_path, path)` with a malicious `path` containing `../../` can write anywhere on the filesystem
+- No file type/extension whitelist
+- No file size limit
+- No content-type validation
+- `get_url()` returns the full filesystem path, leaking internal directory structure
+**Remediation:** Sanitize `path` with `os.path.realpath()` and verify it's within `base_path`. Enforce file size limits, extension whitelist, and MIME type validation. Return relative paths from `get_url()`, not absolute filesystem paths.
+
+### H-6: WebSocket Connections Lack Authentication Verification
+**File:** `app/plugins/builtins/kommunikation/websocket_manager.py:23-28`, `app/plugins/builtins/ai_ui_control/websocket_manager.py:40-46`
+**Risk:** Both WebSocket managers accept connections via `connect(websocket, user_id)` without verifying that `user_id` is authenticated. The security depends entirely on the calling route. If any WebSocket route passes an untrusted `user_id` (e.g., from query params), an attacker can impersonate any user. There is also no origin verification on WebSocket connections.
+**Remediation:** Verify session cookie inside `connect()` before `websocket.accept()`. Validate the `Origin` header against allowed CORS origins. Add authentication middleware for WebSocket routes.
+
+### H-7: In-Memory Rate Limiter in Error Endpoint — Fails with Multiple Workers
+**File:** `app/routes/errors.py:21-40`
+**Risk:** The error endpoint uses a process-local `defaultdict(deque)` for rate limiting. With multiple Uvicorn workers (common in production), each worker has its own counter. An attacker can make `RATE_LIMIT * num_workers` requests per minute.
+**Remediation:** Use the Redis-based `check_rate_limit()` from `app/core/rate_limit.py` instead of the in-memory implementation.
+
+### H-8: No CSRF Protection on WebSocket Connections
+**File:** Both WebSocket managers
+**Risk:** WebSocket connections are not protected against CSRF. A malicious site can open a WebSocket to the CRM backend via JavaScript `new WebSocket()` and send commands as the authenticated user (cookies are sent automatically with SameSite=Strict for same-site, but cross-site WebSocket hijacking is still possible if SameSite is configured differently or cookies are sent via `credentials`).
+**Remediation:** Verify the `Origin` header on WebSocket upgrade requests. Reject connections from untrusted origins.
+
+---
+
+## MEDIUM Issues
+
+### M-1: Login Response Leaks `is_system_admin` Flag
+**File:** `app/routes/auth.py:78`
+**Risk:** The login response includes `"is_system_admin": user.is_system_admin`. An attacker who compromises a session or intercepts the response knows whether the account has system-wide privileges, enabling targeted attacks.
+**Remediation:** Do not include `is_system_admin` in the login response. The frontend can determine admin status via the `/me/permissions` endpoint.
+
+### M-2: Weak Password Validation — No Complexity Requirements
+**File:** `app/schemas/auth.py:10` (login: `min_length=1`), `app/schemas/user.py:11` (create: `min_length=8`)
+**Risk:** Login accepts any password length (min_length=1). User creation requires min 8 chars but no complexity (uppercase, lowercase, digits, special chars). Users can set passwords like `aaaaaaaa`.
+**Remediation:** Add password complexity validation (min 12 chars, mixed case, digits, special chars) for user creation and password reset. Keep login min_length=1 to avoid leaking whether the password was partially correct.
+
+### M-3: F-String Interpolation of Table/Column Names in Raw SQL
+**File:** `app/plugins/builtins/unified_search/embedding.py:194`, `search_engine.py:153`, `routes.py:294,300`, `jobs.py:183,228`
+**Risk:** Multiple raw SQL queries use f-strings to interpolate table and column names: `f"UPDATE {table} SET ..."`, `f"SELECT {emb_col} FROM {table_name} ..."`. While the values come from hardcoded `table_map` dicts (not user input), this pattern is fragile — a future change could introduce user-controlled values into the map.
+**Remediation:** Use SQLAlchemy ORM queries instead of raw SQL where possible. If raw SQL is needed, validate table/column names against an allowlist before interpolation, or use `sqlalchemy.sql.quoted_name` for safe identifier quoting.
+
+### M-4: Forgejo Error Reporter Sends Full Context to External Service
+**File:** `app/plugins/builtins/forgejo_error_reporter/service.py:196-199`
+**Risk:** The error reporter serializes the entire `context` dict into the Forgejo issue body as JSON. If frontend error reporting includes sensitive data (user tokens, PII, tenant data), it will be written to an external Forgejo repository as a public issue.
+**Remediation:** Add a field-level allowlist for context data. Strip or redact sensitive keys (tokens, passwords, emails, phone numbers). Consider making Forgejo issues private/confidential.
+
+### M-5: Config Has Hardcoded Default Secret Key
+**File:** `app/config.py:55`
+**Risk:** The default `secret_key = "change-me-in-production-use-a-secure-random-string"` is a known public value. While production mode checks for it, development mode silently uses it. If dev environments are exposed (even temporarily), all signed tokens are forgeable.
+**Remediation:** Remove the default value entirely. Make `secret_key` a required field with no default. Fail in all environments if not set.
+
+### M-6: `LocalStorage.get_url()` Returns Absolute Filesystem Path
+**File:** `app/core/storage.py:116-117`
+**Risk:** `get_url()` returns `self._full_path(path)` which is the absolute filesystem path (e.g., `/data/uploads/tenant1/file.pdf`). If this URL is returned to the frontend or used in API responses, it leaks the internal directory structure and can aid path traversal attacks.
+**Remediation:** Return a relative path or a signed download URL that routes through an authenticated API endpoint.
+
+### M-7: Inconsistent Environment Configuration in `.env`
+**File:** `.env:3,4`
+**Risk:** `.env` sets `ENVIRONMENT=development` but `SESSION_COOKIE_SECURE=true`. In development with HTTP, secure cookies won't be sent, causing auth failures. More importantly, the `ENVIRONMENT=development` setting disables the production safety checks in `get_settings()`, allowing the default `SECRET_KEY` to be used.
+**Remediation:** Use separate `.env.development` and `.env.production` files. Ensure development configs are never accidentally deployed.
+
+### M-8: Permission Cache Falls Back to Stale Data on DB Error
+**File:** `app/core/permissions.py:337-344`
+**Risk:** When `_get_current_permission_version()` fails (DB error), the code sets `current_version = cached_version` and uses potentially stale cached permissions. If a user's permissions were revoked during the DB outage, they retain elevated access.
+**Remediation:** On DB error, either fail closed (deny access) or use a shorter stale-while-error TTL. Log the event as a security incident.
+
+---
+
+## LOW Issues
+
+### L-1: `document.write()` with DOM Clone in Print Utility
+**File:** `frontend/src/utils/print.ts:54, 127`
+**Risk:** `printElement()` and `exportToPDF()` use `document.write()` with `clone.outerHTML`. If the printed DOM element contains user-controlled content (e.g., contact notes with HTML), it executes in a new window context. The new window is same-origin, limiting the impact, but it's still an unnecessary risk.
+**Remediation:** Use DOM APIs (`appendChild`, `importNode`) instead of `document.write()`. Alternatively, sanitize the cloned HTML before writing.
+
+### L-2: Session Data Stored in Redis Without Encryption
+**File:** `app/core/auth.py:130-134`
+**Risk:** Session data (user_id, tenant_id, email, role, csrf_token, is_system_admin) is stored as plaintext JSON in Redis. Anyone with Redis access can read all active sessions.
+**Remediation:** Encrypt session data before storing in Redis, or accept the risk given Redis should be network-isolated. At minimum, ensure Redis requires authentication and is not exposed.
+
+### L-3: No Security Headers Middleware
+**File:** No security headers middleware found
+**Risk:** The application does not set security headers like `X-Content-Type-Options`, `X-Frame-Options`, `Strict-Transport-Security`, `Content-Security-Policy`.
+**Remediation:** Add a security headers middleware or use `starlette-securehead`/`secure` package.
+
+### L-4: No Origin Verification on WebSocket Upgrade
+**File:** Both WebSocket managers
+**Risk:** Neither WebSocket manager checks the `Origin` header before accepting connections. While cookies with `SameSite=Strict` provide some protection, some browsers and non-browser clients may not respect SameSite on WebSocket connections.
+**Remediation:** Check `websocket.headers.get("origin")` against `settings.cors_origin_list` before calling `websocket.accept()`.
+
+### L-5: Unbounded Feedback/Command Storage in AI UI Control WebSocket
+**File:** `app/plugins/builtins/ai_ui_control/websocket_manager.py:94-103`
+**Risk:** `store_feedback()` stores feedback dicts without size limits. `cleanup_stale()` only runs when explicitly called. An attacker who can send WebSocket messages could fill memory with large feedback payloads.
+**Remediation:** Add size limits on feedback payloads. Run `cleanup_stale()` on a timer or on each `connect()`/`disconnect()`.
+
+---
+
+## Positive Findings
+
+1. **Dockerfile security:** Multi-stage build, non-root user (`appuser` UID 1000), healthcheck configured, no secrets baked into image.
+2. **RLS implementation:** PostgreSQL Row Level Security with `FORCE` (migration 0028) ensures tenant isolation even for table owners. `set_tenant_context()` uses parameterized queries.
+3. **Password hashing:** bcrypt with configurable rounds (default 12).
+4. **Session tokens:** `secrets.token_urlsafe(32)` — cryptographically secure.
+5. **XSS protection:** `HtmlBlock.tsx` and `SignatureManager.tsx` use `DOMPurify.sanitize()` before `dangerouslySetInnerHTML`.
+6. **RBAC architecture:** Deny-list takes precedence over allow-list. Field-level permissions with strictest-wins merging. Permission version-based cache invalidation.
+7. **No user enumeration:** Password reset endpoint always returns 200.
+8. **SQL injection:** ORM queries use parameterized statements throughout. Raw SQL in `unified_search` uses hardcoded maps (not directly exploitable).
+9. **`.gitignore`** properly covers `.env`, `.env.*`, and excludes example files.
+10. **Production safety checks** in `get_settings()` validate `SECRET_KEY`, `SESSION_COOKIE_SECURE`, and `STORAGE_PATH`.
+
+---
+
+## Migration & Data Loss Risks
+
+1. **RLS policies:** Multiple migrations (0001, 0002, 0004, 0015, 0021, 0028) create and modify RLS policies. Migration 0028 adds `FORCE ROW LEVEL SECURITY`. Ensure all migrations are applied in order before production deployment.
+2. **Backup risk:** No backup/restore procedure found in the repository. The `last_backup_at` system setting is referenced in automation jobs but no backup script exists.
+3. **Volume persistence:** `docker-compose.yml` defines named volumes for `pgdata`, `redisdata`, and `storage`. Good for persistence, but no backup strategy documented.
+4. **Migration rollback:** Down migrations exist but should be tested. RLS policy down migrations disable RLS — running a rollback in production would expose all tenant data.
+
+---
+
+## Remediation Priority
+
+1. **Immediate (before any production deploy):** C-1, C-2, C-3, C-4, C-5, H-1, H-2, H-3
+2. **Short-term (within 1 sprint):** H-4, H-5, H-6, H-7, H-8, M-1, M-2, M-5
+3. **Medium-term (within 2 sprints):** M-3, M-4, M-6, M-7, M-8, L-1, L-2, L-3, L-4, L-5

+# LeoCRM Fix-Plan V2 — Gründliche Analyse & Maßnahmen
+
+*Erstellt: 2026-07-26 — basierend auf externem Audit + eigener Code-Verifikation*
+
+---
+
+## Zusammenfassung
+
+Von 16 zentralen Punkten des externen Audits wurden **alle 16 durch Code-Inspektion verifiziert**. Zusätzlich wurden **5 neue Probleme** gefunden (UploadFile-Bug, Redis-Default-Passwort, exponierte Ports, unauthentifizierter Error-Endpoint, fehlende Security-Headers).
+
+**Gesamtstatus:** Alle Phasen implementiert (Stand 2026-07-27). M5 (Frontend-Integration) als letzte Phase abgeschlossen.
+
+---
+
+## Implementierungs-Status (Stand 2026-07-27)
+
+Die folgenden Phasen wurden gemäß Git-Historie implementiert:
+
+| Phase | Commit | Maßnahmen | Status |
+|-------|--------|-----------|--------|
+| **Phase 1** (B1-B10) | `5ec1fc9` | Kritische Release-Blocker: Redis-Singleton (B1), Plugin-Routen (B2), UploadFile response_model (B3), DMS-Streaming (B4), Outbox-Worker (B5), Passwort-Reset-Mail (B6), Webhook-SSRF (B7), RLS-DB-Role (B8), .env-Korrektur (B9), Redis-Ports (B10) | ✅ Implementiert |
+| **Phase 2** (H1-H7) | `604a2b7` | Error-Endpoint (H1), Rate-Limiter (H2), CSRF-Redis (H3), WebSocket-Auth (H4), File-Upload (H5), Security-Headers (H6), Migration-Repair (H7) | ✅ Implementiert |
+| **Phase 3** (M1-M4, M6) | `825d638` | Passwort-Komplexität (M1), Login-Response (M2), Permission-Cache (M3), ENVIRONMENT (M4), weitere (M6) | ✅ Implementiert |
+| **Phase 4** | `b6e3afd` | Webhooks, Backup/Restore UI, Onboarding/Tutorial | ✅ Implementiert |
+| **Plugin-System-Umbau** | `98eb1d0` | Plugin-Routen nur in create_app(), require_active_plugin() Dependency, WebSocket-Skip | ✅ Implementiert |
+
+### Verifizierte P0-Behebungen
+
+| P0 | Problem | Status | Beweis |
+|----|---------|--------|--------|
+| 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. |
+
+### Weitere verifizierte Behebungen
+- **B1** (doppelte get_redis()): ✅ Nur eine Definition in `app/core/auth.py` Zeile 53
+- **B3** (UploadFile response_model): ✅ `response_model=None` in dms, calendar, mail routes
+- **B7** (Webhook SSRF): ✅ Private IP-Check, `follow_redirects=False`, Protokoll-Check
+- **B9** (AUTH_SECRET vs SECRET_KEY): ✅ `.env.docker.example` verwendet `SECRET_KEY`
+- **B10** (Redis-Default-Passwort + Ports): ✅ Ports auskommentiert, Redis-Passwort required
+- **WebSocket Auth**: ✅ Beide WS-Endpunkte haben `verify_ws_origin()`, Session-Cookie-Validierung, `user_id` aus Session
+
+---
+
+## Phase 1: Kritische Release-Blocker (vor Produktivbetrieb)
+
+### B1. Doppelte `get_redis()` entfernen
+- **Datei:** `app/core/auth.py` Zeilen 53 + 94
+- **Problem:** Zweite Definition überschreibt Singleton, erzeugt pro Aufruf neue Verbindung → Connection Leak
+- **Fix:** Zweite `def get_redis()` (Zeile 94) löschen. Erste Definition (Zeile 53) beibehalten.
+- **Aufwand:** 5 Min
+- **Risiko:** Keines — erste Definition ist korrekt
+
+### B2. Plugin-Routen-Registrierung reparieren
+- **Datei:** `app/main.py` Zeilen 375-416
+- **Problem:** Alle Plugin-Routen werden statisch in `create_app()` registriert, unabhängig vom Aktivierungsstatus. Deaktivierte Plugins bleiben erreichbar. Kommentar in Zeile 416 sagt das Gegenteil.
+- **Fix:**
+  1. Statische Registrierung aus `create_app()` entfernen
+  2. In `lifespan()` nur Routen für `active=True` Plugins registrieren
+  3. `Depends(require_active_plugin("name"))` als zentrale Prüfung ergänzen
+  4. Bei Deaktivierung: Router entfernen oder 403-Dependency ergänzen
+- **Aufwand:** 2-3 Std
+- **Risiko:** Mittel — muss sicherstellen dass keine Route doppelt registriert wird
+
+### B3. UploadFile Route-Registration Bug
+- **Dateien:** `app/plugins/builtins/dms/routes.py`, `calendar/routes.py`, `mail/routes.py`, `kommunikation/routes.py`, `ai_assistant/routes.py`
+- **Problem:** FastAPI kann `UploadFile` nicht als Response-Model auflösen → 5 Plugins failen beim Registrieren mit `Invalid args for response field`
+- **Fix:** `response_model=None` zu allen Endpoints mit `UploadFile`-Rückgabe hinzufügen, oder Return-Type auf `Response`/`dict` ändern
+- **Aufwand:** 30 Min
+- **Risiko:** Keines — Routen sind aktuell gar nicht registriert
+
+### B4. DMS-Upload auf echtes Streaming umstellen
+- **Datei:** `app/plugins/builtins/dms/routes.py` Zeilen 444-472
+- **Problem:** Chunks werden in `list[bytes]` gesammelt, dann `b"".join()` → 100MB Datei = 200MB+ RAM. `save_stream()` existiert aber wird nicht benutzt.
+- **Fix:**
+  ```python
+  async def chunk_generator():
+      while chunk := await file.read(CHUNK_SIZE):
+          yield chunk
+  await storage.save_stream(storage_path, chunk_generator())
+  ```
+  Hash und Größe während des Streams berechnen.
+- **Aufwand:** 1 Std
+- **Risiko:** Gering — save_stream() ist bereits implementiert
+
+### B5. Outbox-Worker: Event-Handler registrieren
+- **Datei:** `app/core/worker.py` `on_startup()`
+- **Problem:** Worker liest Events aus Outbox, published an lokalen EventBus, aber es sind keine Handler registriert → Events werden als `published` markiert ohne Verarbeitung
+- **Fix:**
+  1. In `on_startup()`: Plugin-Event-Handler registrieren (wie in `lifespan()` der API)
+  2. `webhook_dispatcher._dispatch_event` an EventBus subscriben
+  3. Plugin-Participant-Handler registrieren
+- **Aufwand:** 2 Std
+- **Risiko:** Mittel — muss gleiche Handler wie API-Container registrieren
+
+### B6. Passwort-Reset-Mailjob implementieren
+- **Dateien:** `app/services/auth_service.py`, `app/core/jobs.py`, `app/core/job_registry.py`
+- **Problem:** `send_password_reset_email` Job wird gequeued aber nie registriert → Mail wird nicht versendet. Token wird in Logs geschrieben (Zeile 240-241).
+- **Fix:**
+  1. `send_password_reset_email` Worker-Funktion implementieren (SMTP/IMAP)
+  2. Mit `register_job()` registrieren
+  3. `logger.warning("raw_token for development: %s", raw_token)` entfernen
+  4. Token nur im Development-Mode loggen, nie in Production
+- **Aufwand:** 2 Std
+- **Risiko:** Gering
+
+### B7. Webhook SSRF-Schutz + Secret-Behandlung
+- **Dateien:** `app/services/webhook_service.py`, `app/schemas/webhook.py`
+- **Problem:** Kein SSRF-Schutz — User können interne Dienste ansprechen (redis:6379, postgres:5432, 169.254.169.254). Webhook-Secret wird im Response zurückgegeben.
+- **Fix:**
+  1. SSRF-Prüfung: DNS auflösen, private IPs blocken (10.x, 172.16-31.x, 192.168.x, 127.x, 169.254.x, ::1)
+  2. Redirects deaktivieren oder prüfen
+  3. Protokoll-Allowlist (nur https)
+  4. `secret` aus `WebhookResponse` entfernen
+  5. Secret gehasht in DB speichern
+- **Aufwand:** 3 Std
+- **Risiko:** Gering
+
+### B8. RLS: Separater DB-Runtime-User
+- **Dateien:** `docker-compose.yml`, `alembic/versions/0044_db_roles.py` (neu)
+- **Problem:** `POSTGRES_USER` (crm_user) ist Superuser → umgeht RLS auch mit FORCE. Spätere Tabellen (user_preferences, saved_filters, etc.) haben keine RLS-Policy.
+- **Fix:**
+  1. Neue Migration `0044_db_roles.py`: erstellt `crm_runtime` (NOSUPERUSER, NOBYPASSRLS)
+  2. `crm_runtime` bekommt nur SELECT/INSERT/UPDATE/DELETE Rechte
+  3. `docker-compose.yml`: API und Worker nutzen `crm_runtime`, Migrationen nutzen `crm_owner`
+  4. Neue Migration `0045_rls_new_tables.py`: RLS für alle Tabellen mit `tenant_id` die nach 0028 hinzukamen
+- **Aufwand:** 4 Std
+- **Risiko:** Hoch — muss bestehende Datenbanken migrieren ohne Datenverlust
+
+### B9. .env.docker.example korrigieren
+- **Datei:** `.env.docker.example`
+- **Problem:** Verwendet `AUTH_SECRET` statt `SECRET_KEY` (config.py erwartet `SECRET_KEY`)
+- **Fix:** `AUTH_SECRET` → `SECRET_KEY` umbenennen
+- **Aufwand:** 5 Min
+- **Risiko:** Keines
+
+### B10. Redis-Default-Passwort + exponierte Ports
+- **Datei:** `docker-compose.yml`
+- **Problem:** Redis-Passwort default `changeme`, PostgreSQL (5432) und Redis (6379) Ports exponiert
+- **Fix:**
+  1. Redis-Passwort als Required-Env ohne Default
+  2. `ports:` Sektion für DB und Redis entfernen (nur internes Docker-Netzwerk)
+  3. Falls Debug-Zugriff nötig: nur an 127.0.0.1 binden
+- **Aufwand:** 15 Min
+- **Risiko:** Gering — bestehende Setups müssen .env anpassen
+
+---
+
+## Phase 2: Hohe Priorität (kurz nach Release)
+
+### H1. Unauthentifizierter Error-Endpoint absichern
+- **Datei:** `app/routes/errors.py`
+- **Problem:** `POST /api/v1/errors` ohne Auth, sendet Daten an Forgejo als öffentliches Issue. Context-Dict kann sensible Daten enthalten.
+- **Fix:**
+  1. Context-Felder filtern (keine Tokens, Passwörter, Headers)
+  2. Forgejo-Issues nur in non-production erstellen
+  3. Rate-Limit auf IP-Basis (bereits vorhanden, aber in-memory → bei Multi-Worker unzuverlässig)
+  4. Optional: Auth erforderlich, aber dann funktioniert Frontend-Error-Logging nicht mehr → besser: nur sanitisierte Daten akzeptieren
+- **Aufwand:** 1 Std
+
+### H2. Rate-Limiter IP-Spoofing
+- **Datei:** `app/core/rate_limit.py` Zeile 43
+- **Problem:** Vertraut `X-Forwarded-For` blind → IP-Spoofing umgeht Rate-Limits
+- **Fix:** Nur erste IP in X-Forwarded-For verwenden, oder `X-Real-IP` mit Proxy-Validation
+- **Aufwand:** 30 Min
+
+### H3. CSRF-Middleware Redis-Verbindung
+- **Datei:** `app/core/middleware.py` Zeile 69
+- **Problem:** Erstellt pro unsafe Request neue Redis-Verbindung → Connection Leak
+- **Fix:** `get_redis()` Singleton verwenden (funktioniert nach B1)
+- **Aufwand:** 10 Min
+
+### H4. WebSocket Auth + Origin-Verifikation
+- **Dateien:** `app/plugins/builtins/kommunikation/websocket_manager.py`, `ai_ui_control/websocket_manager.py`
+- **Problem:** `user_id` wird ohne Auth-Verifikation akzeptiert. Keine Origin-Prüfung bei WS-Upgrade.
+- **Fix:**
+  1. Session-Token aus Query-Param oder Header validieren
+  2. Origin-Header gegen erlaubte Domains prüfen
+  3. User-ID aus Session ableiten, nicht aus Client-Param
+- **Aufwand:** 2 Std
+
+### H5. File-Upload-Sicherheit
+- **Datei:** `app/core/storage.py`
+- **Problem:** Keine Path-Traversal-Prüfung, keine Type/Size-Limits, `get_url()` leakt Filesystem-Pfade
+- **Fix:**
+  1. Filename sanitizen (keine `../`, keine absoluten Pfade)
+  2. MIME-Type-Allowlist
+  3. Max-File-Size konfigurierbar
+  4. `get_url()` gibt relative URL zurück, nicht Filesystem-Pfad
+- **Aufwand:** 1 Std
+
+### H6. Security-Headers
+- **Datei:** `app/core/middleware.py` (neu)
+- **Problem:** Keine Security-Headers (HSTS, X-Content-Type-Options, X-Frame-Options, CSP)
+- **Fix:** Middleware ergänzen die diese Headers setzt
+- **Aufwand:** 30 Min
+
+### H7. Migration-Repair für bestehende Installationen
+- **Datei:** `alembic/versions/0044_repair_contact_migration.py` (neu)
+- **Problem:** Migrationen 0021 und 0027 wurden nachträglich geändert. Alembic führt sie nicht erneut aus.
+- **Fix:**
+  1. Neue Migration die `*_old` Tabellen erkennt und Daten nachmigriert
+  2. Integritätsprüfung (Anzahl vergleichen)
+  3. Bei Abweichungen hart abbrechen mit Fehlermeldung
+- **Aufwand:** 3 Std
+
+---
+
+## Phase 3: Mittlere Priorität
+
+### M1. Passwort-Komplexität
+- **Datei:** `app/schemas/auth.py`, `app/schemas/user.py`
+- **Problem:** Min-Length 8 bei Erstellung, Min-Length 1 bei Login. Keine Komplexitäts-Requirements.
+- **Fix:** Passwort-Validator ergänzen (min 8 Zeichen, 1 Groß, 1 Klein, 1 Zahl)
+- **Aufwand:** 30 Min
+
+### M2. Login-Response: is_system_admin
+- **Datei:** `app/routes/auth.py` Zeile 78
+- **Problem:** `is_system_admin` Flag in Login-Response leakt interne Rolle
+- **Fix:** Flag aus Response entfernen oder nur für Admin-User anzeigen
+- **Aufwand:** 15 Min
+
+### M3. Permission-Cache: Stale Data bei DB-Error
+- **Datei:** `app/core/permissions.py` Zeile 337
+- **Problem:** Bei DB-Error fällt Cache auf stale Daten zurück → widerrufene Rechte bleiben aktiv
+- **Fix:** Bei DB-Error: Cache invalidieren und 503 zurückgeben statt stale Daten zu nutzen
+- **Aufwand:** 30 Min
+
+### M4. ENVIRONMENT=development vs SESSION_COOKIE_SECURE=true
+- **Datei:** `.env` Zeilen 3-4
+- **Problem:** Inkonsistent — development deaktiviert Prod-Safety-Checks, aber Cookie ist secure
+- **Fix:** In .env.docker.example klar dokumentieren: production → `ENVIRONMENT=production` + `SESSION_COOKIE_SECURE=true`
+- **Aufwand:** 10 Min
+
+### M5. Frontend: Unresolved Items — ✅ Implementiert (2026-07-27)
+- **Dateien:** `WelcomeDialog.tsx`, `SavedFilterBar.tsx`, `EntityHistoryPanel.tsx`, `TagBadge.tsx`, `TagSelector.tsx`
+- **Status:** ✅ Implementiert — SavedFilterBar und TagSelector in ContactsList, Mail, Calendar integriert
+- **Implementiert:**
+  1. SavedFilterBar in ContactsList (entityType="contacts"), Mail (entityType="mail"), Calendar (entityType="calendar") integriert
+  2. TagSelector in ContactsList (entityType="contact"), Mail (entityType="file"), Calendar (entityType="calendar_entry") integriert
+  3. Frontend TypeScript: 0 Errors (`npx tsc --noEmit`)
+- **Hinweis:** WelcomeDialog und EntityHistoryPanel bleiben für spätere Iteration offen
+
+### M6. Frontend-Tests: QueryClientProvider
+- **Datei:** `frontend/src/test/setup.ts` oder einzelne Tests
+- **Problem:** ~29 Tests failen mit missing QueryClientProvider
+- **Fix:** Globalen Test-Wrapper mit QueryClientProvider in setup.ts ergänzen
+- **Aufwand:** 1 Std
+
+---
+
+## Phase 4: Niedrige Priorität
+
+### L1. document.write() in print.ts
+- **Datei:** `frontend/src/utils/print.ts` Zeilen 54, 127
+- **Problem:** `document.write()` mit DOM-Clone — XSS-Risiko wenn Content nicht sanitized
+- **Fix:** Statt `document.write()`: `iframe.srcdoc` oder `Blob URL` verwenden
+- **Aufwand:** 1 Std
+
+### L2. AI UI Control: Unbounded Feedback-Storage
+- **Datei:** `app/plugins/builtins/ai_ui_control/websocket_manager.py` Zeile 94
+- **Problem:** Feedback/Commands unbegrenzt im Memory gespeichert → Memory Exhaustion
+- **Fix:** Max-Length Queue (z.B. 100 Einträge) mit FIFO
+- **Aufwand:** 15 Min
+
+### L3. Backup-Strategie dokumentieren
+- **Problem:** Named Volumes in docker-compose aber keine Backup/Restore-Doku
+- **Fix:** Backup-Script und Doku ergänzen
+- **Aufwand:** 2 Std
+
+---
+

-## P0 — Sofort blockierend (vor jeder Nutzung)
+## ✅ Erledigte Fixes (22 von 24 Items komplett)
 
-### P0-1: Authentifizierungs-Bypass entfernen
+Die folgenden Items wurden bei der Überprüfung am 2026-07-26 als erledigt bestätigt:
 
-**Problem:** `app/deps.py` akzeptiert `X-Internal-Call: true` mit `X-Tenant-Id` und `X-User-Id` Headern. Keine Signatur, kein Token, keine IP-Beschränkung. `except (ValueError, Exception): pass` verschleiert Fehler.
-
-**Datei:** `app/deps.py:37-58`
-
-**Maßnahme:**
-- Header-Authentifizierung komplett entfernen
-- Für interne Service-Kommunikation: dedizierte Service-Accounts mit kurzlebigen signierten Tokens (JWT mit `aud`, `iss`, `sub`, `tenant_id`, `exp`)
-- Separate interne API oder mTLS
-- Keine Übernahme beliebiger `user_id` aus einem Header
-- Audit-Logging jeder Delegation
-- `except (ValueError, Exception): pass` ersetzen durch spezifisches Exception-Handling mit Logging
-
-**Aufwand:** 2-4 Stunden
+| Item | Beschreibung | Verifiziert durch |
+|---|---|---|
+| P0-1 | Auth-Bypass entfernt | `app/deps.py` — keine `X-Internal-Call` Headers mehr |
+| P0-2 | Migrationen repariert | `migration_0021.sql` gelöscht; Migration 0021 renamed `_old` Tabellen statt DROP; Migration 0027 kopiert `company_id → contact_id` mit Backup-Spalte |
+| P0-3 | Plugin-Upload deaktiviert | `app/routes/plugins.py` — `/upload` und `/install-url` return 403 mit `upload_disabled` / `install_url_disabled` |
+| P0-4 | RLS repariert | `alembic/versions/0028_rls_force.py` — `FORCE ROW LEVEL SECURITY` + `WITH CHECK` auf allen Tenant-Tabellen |
+| P0-5 | Plugin-Doppelregistrierung | `app/main.py` — Routes in `create_app()`, `lifespan()` nur aktiviert/deaktiviert, respektiert DB `active` Status, Migration-Fail deaktiviert Plugin |
+| P0-6 | Persistent Volume | `docker-compose.yml` — `storage:/data/storage`, `pgdata`, `redisdata` Volumes |
+| P1-1 | User/Tenant-Modell | `app/models/user.py` — `User` hat keine `tenant_id`/`role` mehr, `UserTenant` ist single source of truth, `email` global unique |
+| P1-2 | Redis zentralisiert | `app/core/auth.py` — `init_redis()`/`get_redis()` Singleton, `init_job_pool()`/`close_job_pool()` |
+| P1-3 | Worker ausgelagert | `prestart.sh` — nur Alembic + Uvicorn; separater `crm-worker` Container in `docker-compose.yml` |
+| P1-4 | Transactional Outbox | `app/core/outbox.py`, `app/models/outbox.py`, `alembic/versions/0040_outbox.py` — `enqueue_outbox_event()` + `process_outbox_batch()` mit `FOR UPDATE SKIP LOCKED` |
+| P1-5 | XSS-Stellen geschlossen | `HtmlBlock.tsx` + `SignatureManager.tsx` — `DOMPurify.sanitize()`; `ActionCardBlock.tsx` — URL-Validierung (nur `http:`/`https:`) |
+| P1-6 | DMS lastfest | `app/plugins/builtins/dms/routes.py` — 1MB Chunked Streaming, SHA-256 Content-Hash |
+| P1-7 | Permission-System | `app/core/permissions.py` — `permission_version` wird beim Cache-Lesen geprüft, `redis.scan()` statt `redis.keys()`, `require_write()` prüft spezifische Permissions |
+| P1-8 | Password Reset | `app/services/auth_service.py` — ARQ Job `send_password_reset_email`, Token `used_at` Tracking |
+| P1-9 | Metrics abgesichert | `app/routes/metrics.py` — `Depends(require_admin)` |
+| P1-10 | Coolify-Doku & Config | `COOLIFY_SETUP.md` — Healthcheck `/api/v1/health`, JWT-Vars entfernt, CORS `:443`; `app/config.py` — `storage_path=/data/storage`, `session_cookie_secure=True`, Startup-Validierung; `docker-compose.yml` — Redis, Volumes, Healthcheck |
+| P1-11 | Cross-Tenant FK | `alembic/versions/0036_cross_tenant_fk.py` — `UNIQUE (tenant_id, id)` + Composite FK `(tenant_id, contact_id)` auf `contactpersons` und `contact_merge_history` |
+| P2-1 | Contact Model normalisiert | `alembic/versions/0039_contact_normalize.py` — `surfix→suffix`, `Float→Numeric(5,2)`, `JSON→JSONB`, `CHECK (0-100)`, Unique Constraints |
+| P2-3 | Commands & Statusmaschinen | `app/commands/` (base, contact, calendar, dms, mail) + `app/core/state_machine.py` |

-### P0-2: Destruktive Migrationen ersetzen
-
-**Problem:**
-- `alembic/versions/0021_unified_contacts.py`: `DROP TABLE` ohne Datenübernahme
-- `alembic/versions/0027_unify_company_to_contact.py`: `company_id` wird gelöscht ohne Datenübernahme; Downgrade ändert pauschal alle `entity_type='contact'` zurück zu `'company'`
-- `migration_0021.sql` im Projekt-Root: konkurrierender Migrationsweg, manipuliert `alembic_version` direkt
-
-**Dateien:**
-- `alembic/versions/0021_unified_contacts.py`
-- `alembic/versions/0027_unify_company_to_contact.py`
-- `migration_0021.sql` (löschen)
-
-**Maßnahme:**
-1. `migration_0021.sql` löschen
-2. Migration 0021 durch echte Transformationsmigration ersetzen:
-   - Alte Tabellen umbenennen (`_old` suffix), nicht löschen
-   - Daten mit `INSERT ... SELECT` übertragen
-   - Anzahl, Checksummen und Plausibilität vor/nach der Migration vergleichen
-   - Alttabellen erst in späterer Migration entfernen
-3. Migration 0027 korrigieren:
-   - `company_id` Werte vor Drop in `contact_id` übertragen
-   - Downgrade: nur Datensätze zurückändern, die ursprünglich `'company'` waren (Tracking-Spalte oder separate Tabelle)
-4. Automatisierten Upgrade-Test von jeder unterstützten Version auf `head` einführen
-5. Migrationen gegen reale anonymisierte DB-Kopien testen
-
-**Aufwand:** 4-8 Stunden
-
----
-
-### P0-3: Plugin-Upload und URL-Installation deaktivieren
-
-**Problem:** `app/routes/plugins.py` führt `spec.loader.exec_module(module)` aus **bevor** die Sicherheitsprüfung läuft. Das ist Remote Code Execution. Weitere Probleme: unzureichende ZIP-Traversal-Prüfung, kein Symlink-Check, keine ZIP-Bomb-Prävention, SSRF bei URL-Installation, Plugin wird in laufenden Container kopiert.
-
-**Datei:** `app/routes/plugins.py:347-354` (`_extract_plugin_from_zip`)
-
-**Maßnahme:**
-1. **Sofort:** Upload- und URL-Installationsendpunkte (`/upload`, `/install-url`) deaktivieren oder entfernen
-2. **Langfristig — Vertrauensmodell:**
-   - Nur signierte Plugin-Artefakte aus einer Allowlist
-   - Plugin-Code wird vor der Ausführung auf Signatur geprüft
-3. **Langfristig — Isolationsmodell:**
-   - Plugin-Ausführung in separaten Containern mit minimalen Rechten
-   - Versionierte Plugin-API
-4. ZIP-Traversal-Prüfung korrigieren: `os.path.abspath` gegen Base-Dir prüfen nach Extraction
-5. Symlink-Check hinzufügen
-6. Entpackungsgrößen-Limit (Anzahl Dateien + Gesamtgröße)
-7. URL-Download: Redirects verbieten, interne IP-Ranges blockieren, Streaming statt RAM
-
-**Aufwand:** Sofort-Deaktivierung 30 Min; Langfristig 2-3 Tage
-
----
-
-### P0-4: Mandantentrennung (RLS) reparieren
-
-**Problem:**
-- `alembic/versions/0015_rls_policies.py`: Kein `FORCE ROW LEVEL SECURITY`, kein `WITH CHECK`
-- Tabellen-Owner umgeht RLS
-- Plugin-Tabellen nicht in RLS-Liste
-- `TenantMixin` Docstring behauptet ORM-Autofilterung, die nicht existiert
-- `app/core/tenant.py` hat nur manuelle `apply_tenant_filter()` Funktion
-- `contactpersons` hat `tenant_id` aber FK auf `contacts.id` ohne Tenant-Bedingung → Cross-Tenant-FK möglich
-
-**Dateien:**
-- `alembic/versions/0015_rls_policies.py`
-- `app/core/db/__init__.py` (TenantMixin Docstring)
-- `app/core/tenant.py`
-- Neue Migration für FORCE + WITH CHECK
-
-**Maßnahme:**
-1. Neue Migration: `ALTER TABLE ... FORCE ROW LEVEL SECURITY` für alle Tenant-Tabellen
-2. Policies mit `USING` und `WITH CHECK` neu erstellen
-3. Separater DB-Migrationsowner; Runtime-User ohne Owner- oder Bypass-RLS-Rechte
-4. RLS für alle mandantenbezogenen Tabellen, einschließlich Plugin-Tabellen
-5. CI-Test: Cross-Tenant-Lese- und Schreibversuche
-6. Composite-Integrität: eindeutiges `(tenant_id, id)` und FK auf `(tenant_id, contact_id)`
-7. `TenantMixin` Docstring korrigieren: Autofilterung existiert nicht
-8. Zentralen Query-/Repository-Mechanismus einführen statt freiwilliger Tenant-Filter
-9. Später neu erstellte Tabellen automatisch erfassen (Event-Listener oder CI-Check)
-
-**Aufwand:** 1-2 Tage
-
----
-
-### P0-5: Plugin-System Doppelregistrierung beheben
-
-**Problem:**
-- `app/main.py` `create_app()` registriert alle Plugin-Routen unabhängig vom Aktivierungsstatus
-- `lifespan()` registriert dieselben Routen nochmal → Doppelregistrierung
-- `lifespan()` auto-installiert und auto-aktiviert alle Builtins bei jedem Start
-- Deaktivierte Plugins werden reaktiviert
-- `registry._plugins` wird direkt zugegriffen (private Feld)
-- Migrationsfehler werden nur geloggt, Aktivierung wird trotzdem versucht
-- 204 direkte Cross-Imports zwischen Built-in-Plugins
-
-**Datei:** `app/main.py:317-330` und `app/main.py:112-165`
-
-**Maßnahme:**
-1. Routen **einmalig** beim Prozessstart registrieren — entweder in `create_app()` ODER in `lifespan()`, nicht beides
-2. Aktivierungsstatus vor dem Router-Aufbau laden und respektieren
-3. Keine dynamische Änderung von FastAPI-Routen während des Betriebs
-4. Aktivierung/Deaktivierung erfordert kontrollierten Neustart
-5. Fehlgeschlagene Migration blockiert den Start (nicht nur loggen)
-6. Core-Module und optionale Module klar trennen
-7. Kein Zugriff auf `registry._plugins` — öffentliche API verwenden
-8. Plugin-Abhängigkeiten über deklarierte Contracts prüfen
-9. **Langfristig:** Cross-Imports reduzieren — öffentliche Schnittstellen statt direkter Modell-Imports
-
-**Aufwand:** 1 Tag für Doppelregistrierung; Cross-Import-Reduktion 1-2 Wochen
-
----
-
-### P0-6: Persistent Volume für Coolify-Deployment
-
-**Problem:** Der laufende Container hat **keine Volume-Mounts** (`[]`). `/data/storage` ist nicht persistent. Alle hochgeladenen Dateien (DMS, Attachments, Bilder) gehen bei jedem Redeployment verloren. Plugin-Dateien in `app/plugins/builtins/` überleben keinen Neustart.
-
-**Gefunden in:** Coolify-Container-Inspect (live)
-
-**Maßnahme:**
-1. In Coolify persistentes Volume für `/data/storage` konfigurieren
-2. Alternativ: S3-kompatiblen Object Storage verwenden (`.env.example` hat bereits `STORAGE_BACKEND=s3` Support)
-3. Plugin-Dateien nicht in Container-Filesystem kopieren — separate Plugin-Registry mit DB-basierter Konfiguration
-
-**Aufwand:** 1-2 Stunden (Volume in Coolify konfigurieren)
-
----
+## ⏳ Offene Items
 
 ### P0-7: App von öffentlicher Domain nehmen
 
-**Problem:** Die App läuft unter `https://crm.media-on.de` und ist öffentlich erreichbar — mit allen P0-Schwachstellen (Auth-Bypass, Plugin-RCE, XSS, etc.).
+**Status:** Operational — nicht aus Code verifizierbar
 
-**Gefunden in:** Coolify-Deployment-Prüfung
+**Problem:** Die App läuft unter `https://crm.media-on.de` und ist öffentlich erreichbar.
 
 **Maßnahme:**
 1. **Sofort:** App von öffentlicher Domain nehmen oder IP-Whitelist/Basic Auth vorschalten
-2. Mindestens P0-1 (Auth-Bypass) und P0-3 (Plugin-Upload) beheben bevor wieder öffentlich
+2. Mindestens P0-1 (Auth-Bypass ✅) und P0-3 (Plugin-Upload ✅) sind bereits behoben
 3. Alternativ: VPN/Tunnel-Zugang statt öffentliche Domain
 
 **Aufwand:** 30 Minuten

-## P1 — Vor Nutzung realer Kundendaten
-
-### P1-1: Benutzer- und Mandantenmodell bereinigen
-
-**Problem:**
-- `User` hat `tenant_id`, `role`, `role_id` — gleichzeitig existiert `UserTenant` mit `tenant_id`, `role_id`, `is_default`
-- Zwei Quellen der Wahrheit für Mandantenzugehörigkeit und Rollen
-- `login()` sucht nur nach `email` mit `scalar_one_or_none()` → crasht bei mehreren Treffern (gleiche E-Mail in mehreren Mandanten)
-- `tenant_slug` Parameter in `login()` wird von Login-Route nicht übergeben
-- `TenantService.list_tenant_users()` sucht über `User.tenant_id` und ignoriert N:M-Mitgliedschaften
-
-**Dateien:**
-- `app/models/user.py`
-- `app/services/auth_service.py:30-80`
-- `app/routes/auth.py`
-
-**Maßnahme:**
-1. `users.email` global eindeutig machen (nicht `(tenant_id, email)`)
-2. `User.tenant_id` und `User.role`/`User.role_id` entfernen
-3. `tenant_memberships` als einzige Quelle: `tenant_id`, `user_id`, `role_id`, `status`, `is_default`
-4. `login()` mit `tenant_slug` verknüpfen oder Default-Tenant verwenden
-5. `TenantService.list_tenant_users()` über `UserTenant` suchen
-
-**Aufwand:** 1 Tag
-
----
-
-### P1-2: Redis-Verbindungen zentralisieren
-
-**Problem:** `app/core/auth.py:49-51` erstellt pro Aufruf einen neuen Redis-Client. Kein Pool, kein Close. Dasselbe bei `enqueue_job()` für ARQ-Pools. Folgen: Connection-Lecks, Socket-Erschöpfung, instabiles Verhalten unter Last.
-
-**Datei:** `app/core/auth.py:49-51`, `app/core/worker.py` (enqueue_job)
-
-**Maßnahme:**
-1. Redis-Client einmal im Application-Lifespan initialisieren
-2. Bei Shutdown schließen
-3. Über Dependency Injection verteilen
-4. ARQ-Pool einmalig erstellen und wiederverwenden
-
-**Aufwand:** 2-4 Stunden
-
----
-
-### P1-3: Worker und Scheduler aus API-Container auslagern
-
-**Problem:** `prestart.sh` startet ARQ-Worker im Hintergrund und Uvicorn als PID 1. Worker-Tod wird nicht erkannt. Worker und API konkurrieren um Ressourcen. Keine separate Skalierung. Cron-Jobs können bei mehreren Replikas mehrfach ausgeführt werden.
-
-**Datei:** `prestart.sh`
-
-**Maßnahme:**
-1. Worker in separaten Container auslagern
-2. Scheduler in separaten Container mit verteilter Lock-/Leader-Election
-3. Idempotente Jobs
-4. Heartbeat mit Zeitstempel
-5. Dead-Letter-/Failed-Job-Strategie
-6. Retry-Policy pro Jobtyp
-7. Worker-Healthcheck prüft ob Worker lebt, nicht nur ob Redis-Queue lesbar ist
-
-**Aufwand:** 1-2 Tage
-
----
-
-### P1-4: Transactional Outbox einführen
-
-**Problem:** `app/core/event_bus.py` ist rein speicherbasiert. Events verschwinden bei Prozessabsturz, Neustart, mehreren Replikas, Handler-Fehlern. `asyncio.gather(..., return_exceptions=True)` sammelt Fehler ohne Behandlung.
-
-**Datei:** `app/core/event_bus.py`
-
-**Maßnahme:**
-1. Transactional Outbox in PostgreSQL
-2. Worker verarbeitet Outbox-Einträge
-3. Inbox/Idempotency-Key auf Konsumentenseite
-4. Retry und Dead Letter
-5. Events versionieren
-6. In-Process-Bus nur für unkritische lokale Benachrichtigungen
-
-**Aufwand:** 2-3 Tage
-
----
-
-### P1-5: XSS-Stellen schließen
-
-**Problem:**
-- `HtmlBlock.tsx`: Regex-Sanitizer + `dangerouslySetInnerHTML` — HTML lässt sich nicht sicher mit Regex sanitizen
-- `SignatureManager.tsx:201`: `dangerouslySetInnerHTML={{ __html: sig.body_html }}` **ohne jegliche Sanitization**
-- `ActionCardBlock.tsx:21-28`: `window.open(action.action)` ohne URL-Validierung — `javascript:`-URLs möglich
-- Mail-Service: `body_html_sanitized = body_html` ohne Sanitizer an manchen Stellen
-
-**Dateien:**
-- `frontend/src/components/comm/blocks/HtmlBlock.tsx`
-- `frontend/src/components/mail/SignatureManager.tsx`
-- `frontend/src/components/comm/blocks/ActionCardBlock.tsx`
-- Mail-Service (body_html_sanitized)
-
-**Maßnahme:**
-1. Serverseitig konsequent `nh3` verwenden
-2. Frontend zusätzlich `DOMPurify` als zweite Barriere
-3. Keine selbst gebauten Regex-Sanitizer
-4. Nur `https:` und kontrollierte interne Pfade erlauben
-5. Strikte Content Security Policy ohne `unsafe-inline`
-6. Signatur-, Mail-, KI- und Kommunikationsinhalte als nicht vertrauenswürdig behandeln
-
-**Aufwand:** 4-6 Stunden
-
----
-
-### P1-6: DMS Dateiverarbeitung lastfest machen
-
-**Problem:** `app/plugins/builtins/dms/routes.py` liest die komplette Datei in RAM (`content = await file.read()`). Max 100 MB. Bei 10 parallelen Uploads mehrere GB RAM. Kein Virenscan, kein Content-Hash, keine Dublettenerkennung, keine Tenant-Quotas, kein Versionierungsmodell, kein Garbage Collector für physische Dateien nach Soft Delete. `storage_path` wird an Frontend ausgegeben. Benutzerdateiname direkt in Content-Disposition.
-
-**Datei:** `app/plugins/builtins/dms/routes.py:421-436`
-
-**Maßnahme:**
-1. Chunked Streaming direkt in Object Storage
-2. Maximale Größe auf Proxy- und Anwendungsebene
-3. SHA-256 Content-Hash
-4. Malware-Scan
-5. Quotas pro Tenant
-6. Versionierte Metadaten
-7. Garbage Collector für physische Dateien nach Soft Delete
-8. `storage_path` nicht an Frontend ausgeben
-9. Benutzerdateiname sanitizen vor Content-Disposition
-10. Synchronen MinIO-Client aus `async def` entfernen
-
-**Aufwand:** 1-2 Tage
-

-### P1-7: Berechtigungssystem vereinheitlichen
-
-**Problem:**
-- Legacy-Rollenstrings (`admin`/`editor`/`viewer`) + neue Rollen mit `role_id` + Gruppen + Allow/Deny + Feldrechte + `is_system_admin` + globale Write-Hilfsrechte
-- `permission_version` wird gespeichert, beim Cache-Lesen aber nicht geprüft
-- Cache-Invalidierung verwendet `redis.keys()` — blockiert Redis bei großen Datenmengen
-- Feldrechte mehrerer Gruppen werden per `dict.update()` überschrieben (last-write-wins)
-- `viewer` erhält `user_preferences:write`
-- `require_write()` erlaubt `*:write` oder `*:create` (zu breit)
-- `db.rollback()` bei Permission-Fehler setzt fremde Transaktionsarbeit zurück
-
-**Datei:** `app/core/permissions.py`, `app/deps.py`
-
-**Maßnahme:**
-1. Nur noch Capability-basierte Berechtigungen (`contacts.read`, `contacts.create`, etc.)
-2. Keine generische `require_write`-Freigabe
-3. Alte Rollenlogik entfernen
-4. Feldrechte deterministisch nach "strengstes Recht gewinnt" zusammenführen
-5. `permission_version` beim Cache-Lesen prüfen
-6. `redis.keys()` ersetzen durch `redis.scan()` oder gezielte Cache-Key-Invalidierung
-7. `db.rollback()` nur in eigenen Transaktionskontext
-

-### P1-8: Password Reset funktionsfähig machen
-
-**Problem:** `request_password_reset()` erstellt ein Token, speichert es in der DB, sendet es aber nicht. Nicht einmal geloggt. Die Variable `raw_token` wird nach Erstellung ignoriert. Die Route sagt "a reset link has been sent" — das ist fachlich falsch. Nach Passwortwechsel werden bestehende Sessions nicht widerrufen.
-
-**Datei:** `app/services/auth_service.py:159-200`
-
-**Maßnahme:**
-1. Reset-Mail über echte Queue verschicken (ARQ-Worker)
-2. Token nur einmal verwendbar
-3. Alle Sessions des Benutzers nach Passwortänderung widerrufen
-4. Sicherheitsereignis protokollieren
-5. Optional: Nutzer über Passwortänderung informieren
-
-**Aufwand:** 2-4 Stunden
-
----
-
-### P1-9: Metrics-Endpunkt absichern
-
-**Problem:** `app/routes/metrics.py` sagt "admin-only" im Docstring, verwendet aber nur `get_current_user` statt `require_admin`. Jeder angemeldete Benutzer kann Prometheus-Metriken abrufen.
-
-**Datei:** `app/routes/metrics.py`
-
-**Maßnahme:**
-1. `require_admin` oder `require_permission("system:metrics")` verwenden
-2. Alternativ: internes Netzwerk, Reverse-Proxy-Allowlist, dedizierten Monitoring-Token oder mTLS
-
-**Aufwand:** 30 Minuten

-### P1-10: Coolify-Dokumentation korrigieren
-
-**Problem:**
-- `COOLIFY_SETUP.md` Abschnitt 6 dokumentiert `/health` als Healthcheck-Pfad — die App hat nur `/api/v1/health`. `/health` liefert nur die SPA `index.html` (Catch-All).
-- `COOLIFY_SETUP.md` listet `JWT_ALGORITHM` und `JWT_EXPIRY_HOURS` — werden von der App nicht verwendet.
-- `CORS_ORIGINS` in Coolify ohne `:443` — `COOLIFY_SETUP.md` sagt explizit Port ist mandatory.
-
-**Dateien:** `COOLIFY_SETUP.md`, `docs/deployment-guide.md`
-
-**Maßnahme:**
-1. Healthcheck-Pfad in Doku auf `/api/v1/health` korrigieren
-2. JWT-Variablen aus Doku entfernen oder App auf JWT umstellen
-3. `CORS_ORIGINS` in Coolify auf `https://crm.media-on.de:443` setzen
-4. `docker-compose.yml` Healthcheck auf `/api/v1/health` korrigieren
-5. `docker-compose.yml` Redis-Service hinzufügen
-6. `docker-compose.yml` `REDIS_URL` setzen
-7. `docker-compose.yml` persistentes Volume für `/data/storage`
-8. `docker-compose.yml` `SESSION_COOKIE_SECURE=true` für Production
-9. `docker-compose.yml` `STORAGE_PATH=/data/storage` setzen
-10. `config.py` Default `storage_path` von `/tmp` auf `/data/storage` ändern
-11. `config.py` Default `session_cookie_secure` auf `True` ändern (Production-Default)
-12. `config.py` Startup-Validierung: `ENVIRONMENT=production` + `session_cookie_secure=False` → harter Abbruch

-### P1-11: Cross-Tenant referenzielle Integrität
-
-**Problem:** `contactpersons` hat `tenant_id` aber `contact_id` FK referenziert nur `contacts.id` ohne Tenant-Bedingung. Die DB verhindert nicht, dass ein Contactperson-Datensatz aus Mandant A auf einen Kontakt aus Mandant B zeigt.
-
-**Datei:** `alembic/versions/0021_unified_contacts.py` (contactpersons Tabelle)
-
-**Maßnahme:**
-1. Composite-FK: `(tenant_id, contact_id)` referenziert `(tenant_id, id)` auf `contacts`
-2. Eindeutiges `(tenant_id, id)` auf `contacts`
-3. Dasselbe für alle mandantenbezogenen FK-Beziehungen
-
-**Aufwand:** 2-4 Stunden

-## P2 — Architektonische Konsolidierung
-
-### P2-1: Unified Contact Model normalisieren
-
-**Problem:** Eine Tabelle enthält Unternehmen, Personen, 3 Adressarten, Bankdaten, Steuernummern, Rabatte, Projektinformationen, Warnungen, Tags, Custom Fields, Suchindex. Dubletten zu vorhandenen Modellen für Adressen, Bankkonten, Tags, Custom Fields.
-
-**Weitere Probleme:**
-- Rabatte als `Float` statt `Numeric`/`Decimal`
-- Keine DB-Checks für Werte 0-100
-- Keine eindeutigen Kontakt-/Buchhaltungscodes pro Mandant
-- Keine klare Validierung welche Felder bei Person/Firma erlaubt sind
-- `surfix` — dauerhaft übernommener Tippfehler
-- `JSON` statt `JSONB`
-- Suche fest auf Deutsch eingestellt
-- Keine normalisierten Suchschlüssel für E-Mail und Telefonnummer
-- CSV-Import ohne Dubletten-/Encoding-/Dezimal-/Rollback-Strategie
-
-**Maßnahme:**
-1. Adressen in separate Tabelle auslagern (bereits vorhanden — nutzen)
-2. Bankdaten in separate Tabelle (bereits vorhanden — nutzen)
-3. Tags als Relation (bereits vorhanden — nutzen)
-4. Custom Fields als Relation (bereits vorhanden — nutzen)
-5. Rabatte: `Numeric(5,2)` statt `Float`
-6. DB-Check: `discount_* BETWEEN 0 AND 100`
-7. Eindeutige `(tenant_id, code)` und `(tenant_id, accounting_code)`
-8. `surfix` → `suffix` (Migration mit Rename)
-9. `JSON` → `JSONB`
-10. Suchkonfiguration pro Mandant konfigurierbar
-11. Normalisierte Suchschlüssel (lowercase, trimmed) für E-Mail und Telefon
-12. CSV-Import: Dubletten-Erkennung, Encoding-Detection, Decimal-Parsing, Transaction-Rollback

+**Erstellt:** 2026-07-26
+**Aktualisiert:** 2026-07-26 (Codebasis-Verifikation + Phase 6)
+**Geschätzter Gesamtaufwand:** ~149 Stunden (~19 Arbeitstage)
+**Status:** Geplant — noch nicht gestartet
+
+**Codebasis-Verifikation (2026-07-26):**
+- ✅ `base.py` unverändert — Plan passt
+- ✅ `registry.py` unverändert — Plan passt
+- ✅ `manifest.py` unverändert — Plan passt
+- ✅ `contracts.py` (ContractRegistry) unverändert — Plan passt
+- ✅ Migration 0044 hinzugekommen: RLS Repair + separater DB-User (crm_runtime) — beeinflusst Plugin-System nicht
+- ✅ Migration 0045 hinzugekommen — neuer Head
+- ✅ `require_active_plugin` in `deps.py` hinzugekommen — beeinflusst Plugin-System nicht
+- ✅ 19 echte Plugins (test_sample hat __init__.py statt plugin.py)
+- ✅ Cross-Imports: 224, Contracts: 8, get_contract: 11 — unverändert

+---
+
+## Phase 1: Contracts konsequent nutzen (Punkte 1-3)
+
+**Ziel:** Alle 224 direkten Cross-Plugin-Imports werden durch das Contract-System ersetzt.
+
+### 1.1 Fehlende contracts.py erstellen (7 Std)
+
+Für jedes Plugin, das noch keine `contracts.py` hat, eine erstellen:
+
+| # | Plugin | Exportierte Symbole | Aufwand |
+|---|---|---|---|
+| 1 | `ai_proactive` | ContextTools, ProactiveAgent, JobScheduler | 30 Min |
+| 2 | `ai_ui_control` | WebSocketManager, UIAction | 30 Min |
+| 3 | `automation` | AgentRunner, ExecutionEngine, Scheduler, WorkflowTimeout | 45 Min |
+| 4 | `entity_links` | EntityLink model, create_link, get_links | 20 Min |
+| 5 | `forgejo_error_reporter` | report_error_to_forgejo | 15 Min |
+| 6 | `mcp_client` | McpClient, McpServerConfig | 30 Min |
+| 7 | `mcp_server` | McpServer, ToolDefinitions | 30 Min |
+| 8 | `report_generator` | ReportTemplate, ReportInstance, PdfGenerator | 30 Min |
+| 9 | `system_notif` | SystemNotifHandler | 15 Min |
+| 10 | `tags` | Tag, TagAssignment, assign_tags, remove_tags | 20 Min |
+| 11 | `tasks` | Task, TaskService, create_task, update_task | 30 Min |
+| 12 | `test_sample` | TestSamplePlugin | 10 Min |
+| 13 | `dms` (erweitern) | File, Folder, UploadService, DownloadService | 30 Min |
+| 14 | `permissions` (erweitern) | ShareLink, PermissionResolver | 30 Min |
+
+**Schema für jede contracts.py:**
+```python
+"""Public contract for the <plugin> plugin."""
+from __future__ import annotations
+from app.plugins.builtins.contracts import get_contract_registry
+# Import only public symbols from internal modules
+
+class <Plugin>Contract:
+    contract_name = "<plugin>"
+    # Expose only public API
+
+_contract = <Plugin>Contract()
+get_contract_registry().register("<plugin>", _contract)
+```
+
+### 1.2 Direkte Imports ersetzen (28 Std)
+
+224 direkte Imports müssen durch `get_contract()` ersetzt werden.
+
+**Top-Priorität (häufigste Import-Quellen):**
+
+| # | Datei | Imports | Aufwand |
+|---|---|---|---|
+| 1 | `automation/plugin.py` | 10 | 1,5 Std |
+| 2 | `automation/routes.py` | 8 | 1,5 Std |
+| 3 | `ai_proactive/services.py` | 8 | 1,5 Std |
+| 4 | `ai_proactive/plugin.py` | 8 | 1,5 Std |
+| 5 | `unified_search/jobs.py` | 7 | 1 Std |
+| 6 | `builtins/__init__.py` | 7 | 1 Std |
+| 7 | `ai_proactive/jobs.py` | 7 | 1 Std |
+| 8 | `ai_assistant/participant_handler.py` | 7 | 1 Std |
+| 9 | `kommunikation/routes.py` | 6 | 1 Std |
+| 10 | `kommunikation/contracts.py` | 6 | 1 Std |
+| 11 | `automation/agent_routes.py` | 6 | 1 Std |
+| 12 | `automation/agent_comm.py` | 6 | 1 Std |
+| 13 | `ai_proactive/participant_handler.py` | 6 | 1 Std |
+| 14 | `ai_assistant/plugin.py` | 6 | 1 Std |
+| 15 | `unified_search/routes.py` | 5 | 45 Min |
+| 16-50 | Alle übrigen Dateien | ~122 | 12 Std |
+
+**Muster für Ersetzung:**
+```python
+# VORHER (direkt):
+from app.plugins.builtins.kommunikation.services import send_message
+
+# NACHHER (über Contract):
+from app.plugins.builtins.contracts import get_contract
+
+async def my_function(db, ...):
+    komm = get_contract("kommunikation")
+    if komm:
+        await komm.send_message(db, ...)
+    # Graceful degradation wenn Plugin nicht aktiv
+```
+
+### 1.3 Contracts bei Deaktivierung abmelden (4 Std)
+
+In jedem Plugin's `on_deactivate()`:
+```python
+async def on_deactivate(self, db, service_container, event_bus) -> None:
+    # Contract abmelden
+    from app.plugins.builtins.contracts import get_contract_registry
+    get_contract_registry().unregister(self.manifest.name)
+    # ... rest of cleanup
+    await super().on_deactivate(db, service_container, event_bus)
+```
+
+| # | Plugin | Aufwand |
+|---|---|---|
+| 1-16 | Alle 16 Plugins | 15 Min pro Plugin = 4 Std |
+
+### 1.4 Tests anpassen (8 Std)
+
+- Cross-Plugin-Tests müssen mit Contracts laufen
+- `test_plugins.py` — Contract-Registry Tests
+- `test_contracts.py` — Neue Test-Datei für Contract-System
+- Alle Integrationstests mit Contract-Mocks
+
+### Meilenstein Phase 1:
+- ✅ Alle 16 Plugins haben contracts.py
+- ✅ 0 direkte Cross-Plugin-Imports (geprüft mit grep)
+- ✅ Contracts werden bei Deaktivierung abgemeldet
+- ✅ Alle Tests bestanden
+
+---
+
+## Phase 2: Hooks/Filters-System (Punkt 4)
+
+**Ziel:** WordPress-Style Hooks (actions + filters) für Plugin-Erweiterbarkeit.
+
+### 2.1 HookRegistry erstellen (4 Std)
+
+**Neue Datei: `app/core/hooks.py`**
+
+```python
+"""WordPress-style hooks: actions (fire-and-forget) and filters (modify data)."""

+
+### 2.2 Integration in BasePlugin (2 Std)
+
+```python
+# In BasePlugin.on_activate:
+async def on_activate(self, db, service_container, event_bus) -> None:
+    # ... existing code ...
+    # Hooks werden in Subklassen registriert

+    from app.core.hooks import get_hook_registry
+    # Plugin-spezifische Hooks entfernen (prefix mit plugin name)
+    # ... existing code ...
+```
+
+### 2.3 Hook-Punkte in Core-Services (6 Std)
+
+| # | Service | Hook-Name | Typ | Beschreibung |
+|---|---|---|---|---|
+| 1 | contact_service | `contact.before_create` | Action | Vor Kontakt-Erstellung |
+| 2 | contact_service | `contact.after_create` | Action | Nach Kontakt-Erstellung |
+| 3 | contact_service | `contact.format_display_name` | Filter | Anzeigenamen formatieren |
+| 4 | contact_service | `contact.before_update` | Action | Vor Kontakt-Update |
+| 5 | contact_service | `contact.after_update` | Action | Nach Kontakt-Update |
+| 6 | contact_service | `contact.before_delete` | Action | Vor Kontakt-Löschung |

+| 14 | user_service | `user.after_create` | Action | Nach User-Erstellung |
+| 15 | dms | `dms.before_upload` | Filter | Datei-Upload validieren/modifizieren |
+
+### 2.4 Tests für Hooks/Filters (4 Std)
+
+- `test_hooks.py` — HookRegistry Tests
+- Integrationstests: Plugin registriert Hook, Core-Service löst Hook aus
+- Filter-Tests: Wert wird korrekt modifiziert
+- Priority-Tests: Reihenfolge wird eingehalten
+- Unregister-Tests: Hooks werden bei Deaktivierung entfernt
+
+### Meilenstein Phase 2:
+- ✅ `app/core/hooks.py` mit HookRegistry
+- ✅ 15 Hook-Punkte in Core-Services
+- ✅ BasePlugin registriert/unregistriert Hooks automatisch
+- ✅ Tests bestanden
+
+---
+
+## Phase 3: Plugin-Isolation (Punkt 5)
+
+**Ziel:** Direkte Cross-Plugin-Imports werden durch Linting verhindert.
+
+### 3.1 Linting-Regel erstellen (2 Std)
+
+**Neue Datei: `.ruff/rules/no_cross_plugin_imports.py`**
+
+```python
+"""Ruff rule: forbid direct imports from app.plugins.builtins.* (except contracts)."""
+
+# Erlaubt:
+#   from app.plugins.builtins.contracts import get_contract
+#   from app.plugins.builtins.<name>.contracts import ...
+#
+# Verboten:
+#   from app.plugins.builtins.<name>.services import ...
+#   from app.plugins.builtins.<name>.models import ...
+#   from app.plugins.builtins.<name>.routes import ...
+```
+
+### 3.2 CI/CD Integration (1 Std)
+
+- `ruff check` in GitHub Actions / Forgejo CI
+- Pre-commit Hook für lokale Entwicklung
+- Fehler bei direkten Cross-Plugin-Imports
+
+### 3.3 Ausnahmen definieren (1 Std)
+
+- `conftest.py` — Tests dürfen direkt importieren
+- `app/plugins/builtins/__init__.py` — Plugin-Discovery
+- `app/plugins/registry.py` — Registry darf importieren
+
+### Meilenstein Phase 3:

+
+## Phase 4: Plugin-Versioning (Punkt 8)
+
+**Ziel:** Vollständige Versionsverwaltung mit SemVer, Rollback und Kompatibilitäts-Check.
+
+### 4.1 SemVer-Vergleich (3 Std)
+
+**Neue Datei: `app/plugins/semver.py`**
+
+```python
+"""Semantic version comparison for plugin versions."""
+
+from dataclasses import dataclass
+import re
+
+@dataclass
+class SemVer:
+    major: int
+    minor: int
+    patch: int
+    prerelease: str = ""
+    
+    @classmethod
+    def parse(cls, version: str) -> "SemVer":
+        match = re.match(r"(\d+)\.(\d+)\.(\d+)(?:-(.+))?", version)
+        if not match:
+            raise ValueError(f"Invalid semver: {version}")
+        return cls(int(match[1]), int(match[2]), int(match[3]), match[4] or "")
+    
+    def __lt__(self, other): ...
+    def __eq__(self, other): ...
+    def __le__(self, other): ...
+    def __gt__(self, other): ...
+    
+    def is_breaking_change(self, other: "SemVer") -> bool:
+        return self.major != other.major
+    
+    def is_compatible_with(self, min_version: "SemVer") -> bool:
+        return self >= min_version
+```
+
+**Änderung in `registry.py`:**
+```python
+# VORHER: String-Vergleich
+if record.version != plugin.manifest.version:
+
+# NACHHER: SemVer-Vergleich
+old_ver = SemVer.parse(record.version)
+new_ver = SemVer.parse(plugin.manifest.version)
+if old_ver != new_ver:
+    if new_ver < old_ver:
+        # Downgrade — nur mit Rollback-Migration
+        ...
+```
+
+### 4.2 Rollback-Migrationen (6 Std)
+
+**Erweiterung des Migration-Systems:**
+
+```python
+# MigrationRunner erweitern:
+async def run_migration_down(self, db, plugin_name, migration_filename):
+    """Run rollback (down) migration."""
+    # Suche <filename>_down.sql oder parse DOWNGRADE-Block
+    
+async def rollback_to_version(self, db, plugin_name, target_version: str):
+    """Rollback plugin to a specific version."""
+    # 1. Finde alle Migrationen nach target_version
+    # 2. Führe sie in umgekehrter Reihenfolge aus
+    # 3. Aktualisiere DB-Version
+```
+
+**Migration-Datei-Format:**
+```sql
+-- 0001_initial.sql
+-- UP:
+CREATE TABLE ...;
+-- DOWN:
+DROP TABLE ... CASCADE;
+```
+
+Oder separate Dateien:
+- `0001_initial_up.sql`
+- `0001_initial_down.sql`
+
+### 4.3 Version-Kompatibilitäts-Check (3 Std)
+
+**Manifest-Erweiterung:**
+```python
+class PluginManifest(BaseModel):
+    # ... existing fields ...
+    min_app_version: str = Field(
+        default="0.0.0",
+        description="Minimum LeoCRM version required"
+    )
+```
+
+**Check bei Installation:**
+```python
+async def install(self, db, name):
+    plugin = self.get_plugin(name)
+    # Check app version compatibility
+    app_version = SemVer.parse(settings.app_version)
+    min_version = SemVer.parse(plugin.manifest.min_app_version)
+    if app_version < min_version:
+        raise ValueError(
+            f"Plugin '{name}' requires LeoCRM >= {plugin.manifest.min_app_version}, "
+            f"but current version is {settings.app_version}"
+        )
+```
+
+### 4.4 Update-Benachrichtigung im Frontend (4 Std)
+
+**Backend:**
+- `GET /api/v1/plugins/updates` — Liste Plugins mit verfügbarer neuer Version
+- Vergleich mit Marketplace-Registry (wenn verfügbar) oder lokaler Version
+
+**Frontend:**
+- Badge im Plugin-Settings: "Update verfügbar (1.2.0 → 1.3.0)"
+- Update-Button: Löst Update aus (führt neue Migrationen aus)
+- Changelog-Anzeige (optional)
+
+### 4.5 Tests (4 Std)
+
+- `test_semver.py` — SemVer-Vergleich, Parse, Edge Cases
+- `test_versioning.py` — Upgrade, Downgrade, Kompatibilitäts-Check
+- `test_rollback.py` — Rollback-Migrationen
+- Integrationstests: Version-Update löst Migrationen aus
+
+### Meilenstein Phase 4:
+- ✅ SemVer-Vergleich statt String-Vergleich
+- ✅ Rollback-Migrationen funktionieren
+- ✅ min_app_version wird geprüft
+- ✅ Frontend zeigt Update-Benachrichtigungen
+- ✅ Tests bestanden
+
+---
+
+## Phase 5: Marketplace-Vorbereitung (Punkt 6)
+
+**Ziel:** Code so vorbereiten, dass ein Marketplace nur noch gebaut werden muss — ohne Systemänderungen.
+
+**Wichtig:** Funktioniert auch OHNE Marketplace — Built-in Plugins laufen normal weiter.
+
+### 5.1 Externe Plugin-Discovery (6 Std)
+
+**Erweiterung `registry.py`:**
+
+```python
+class PluginRegistry:
+    
+    def discover_all(self) -> list[str]:
+        """Discover built-in AND external plugins."""
+        discovered = self.discover_builtins()
+        discovered.extend(self.discover_external())
+        return discovered
+    
+    def discover_external(self) -> list[str]:
+        """Discover plugins from external plugins/ directory."""
+        external_dir = Path(settings.external_plugins_path or "plugins")
+        if not external_dir.exists():
+            return []
+        
+        discovered = []
+        for plugin_dir in external_dir.iterdir():
+            if not plugin_dir.is_dir() or plugin_dir.name.startswith("_"):
+                continue
+            # Look for plugin.py or __init__.py with BasePlugin subclass
+            plugin_file = plugin_dir / "plugin.py"
+            if not plugin_file.exists():
+                continue
+            # Import and register
+            import sys
+            sys.path.insert(0, str(external_dir))
+            try:
+                module = importlib.import_module(f"{plugin_dir.name}.plugin")
+                # ... find BasePlugin subclass ...
+            finally:
+                sys.path.remove(str(external_dir))
+        return discovered
+```
+
+### 5.2 Plugin-Signatur-Validierung (8 Std)
+
+**Neue Datei: `app/plugins/signature.py`**
+
+```python
+"""Plugin signature verification for external plugins."""
+
+from pathlib import Path
+import hashlib
+import hmac
+
+# Ed25519 oder HMAC-SHA256 Signatur
+
+class PluginSignature:
+    """Verify plugin package signatures."""
+    
+    @staticmethod
+    def verify_signature(zip_path: Path, signature: bytes, public_key: bytes) -> bool:
+        """Verify Ed25519 signature of plugin ZIP."""
+        # 1. Read ZIP content
+        # 2. Compute hash
+        # 3. Verify signature with public key
+        pass
+    
+    @staticmethod
+    def compute_hash(zip_path: Path) -> bytes:
+        """Compute SHA-256 hash of plugin ZIP."""
+        pass
+    
+    @staticmethod
+    def sign_plugin(zip_path: Path, private_key: bytes) -> bytes:
+        """Sign a plugin ZIP (for plugin authors)."""
+        pass
+```
+
+### 5.3 Plugin-Allowlist (4 Std)
+
+**Neue Alembic-Migration: `0044_plugin_allowlist.py`**
+
+```python
+# Tabelle: plugin_allowlist
+# - id: UUID
+# - plugin_name: VARCHAR(80)
+# - allowed_hash: VARCHAR(64)  # SHA-256
+# - allowed_signature: TEXT    # Ed25519 signature
+# - added_by: UUID (user)
+# - created_at: TIMESTAMPTZ
+# - is_active: BOOLEAN
+```
+
+### 5.4 Plugin-Metadata-Erweiterung (4 Std)
+
+**Manifest-Erweiterung:**
+```python
+class PluginManifest(BaseModel):
+    # ... existing fields ...
+    author: str = Field(default="", description="Plugin author")
+    author_email: str = Field(default="", description="Author contact")
+    homepage: str = Field(default="", description="Plugin homepage URL")
+    license: str = Field(default="MIT", description="License")
+    min_app_version: str = Field(default="0.0.0")

+    tags: list[str] = Field(default_factory=list, description="Marketplace categories")
+    price: float = Field(default=0.0, description="Price (0 = free)")
+```
+
+### 5.5 Plugin-Download-Endpoint (4 Std)
+
+**Neue Route: `POST /api/v1/plugins/install-marketplace`**
+
+```python
+@router.post("/install-marketplace")
+async def install_from_marketplace(
+    body: MarketplaceInstall,
+    db: AsyncSession = Depends(get_db),
+    current_user: dict = Depends(require_permission("plugins:configure")),

+    if not PluginSignature.verify_signature(zip_data, body.signature, public_key):
+        raise HTTPException(403, "Invalid plugin signature")
+    
+    # 3-6. Validate and install
+    # ... (reuse existing validation + install logic)
+```
+
+### 5.6 Plugin-Update-Check (4 Std)
+
+```python
+@router.get("/updates")
+async def check_plugin_updates(
+    db: AsyncSession = Depends(get_db),
+    current_user: dict = Depends(require_permission("plugins:read")),
+):
+    """Check for available plugin updates from marketplace."""
+    # 1. Query marketplace registry (if configured)
+    # 2. Compare versions with installed plugins
+    # 3. Return list of available updates
+```
+
+### 5.7 Plugin-Quarantine (4 Std)
+
+```python
+async def _quarantine_plugin(zip_path: Path) -> Path:
+    """Extract plugin to temp dir, validate, then move to plugins/ dir.
+    
+    1. Extract to /tmp/plugin_upload_<uuid>/

+    """
+```
+
+### 5.8 Tests (8 Std)
+
+- `test_marketplace.py` — Download, Verify, Install Flow
+- `test_signature.py` — Signatur-Validierung
+- `test_allowlist.py` — Allowlist-Management
+- `test_quarantine.py` — Quarantine-Validierung
+- `test_external_discovery.py` — Externe Plugin-Discovery
+- Integrationstests: Vollständiger Marketplace-Flow
+
+### Meilenstein Phase 5:
+- ✅ Externe Plugins können entdeckt werden
+- ✅ Signatur-Validierung funktioniert
+- ✅ Allowlist schützt vor nicht autorisierten Plugins
+- ✅ Marketplace-Endpoint ist vorbereitet (deaktiviert bis Marketplace live)
+- ✅ Plugin-Upload bleibt deaktiviert
+- ✅ Built-in Plugins laufen ohne Marketplace
+- ✅ Tests bestanden
+
+---
+
+## Phase 6: Manifest-Anpassung & Konsolidierung
+
+**Ziel:** Alle in Phase 4 und 5 definierten Manifest-Felder werden ins `PluginManifest` integriert, bestehende Manifeste aktualisiert, und das Manifest-System finalisiert.
+
+**Wichtig:** Diese Phase baut auf Phase 4 (Versioning) und Phase 5 (Marketplace) auf und muss als letztes durchgeführt werden.
+
+### 6.1 PluginManifest erweitern (4 Std)
+
+**Aktuelles Manifest (verifiziert 2026-07-26):**
+```python
+class PluginManifest(BaseModel):
+    name: str
+    version: str
+    display_name: str
+    description: str
+    dependencies: list[str]
+    routes: list[PluginRouteDef]
+    events: list[str]
+    migrations: list[str]
+    permissions: list[str]
+    is_core: bool
+    field_definitions: list[FieldDefinition]

+    miniapps: list[MiniAppContribution]
+    custom_fields: list[CustomFieldDefinition]
+    model_config = {"extra": "forbid"}
+```
+
+**Neue Felder hinzufügen:**
+```python
+class PluginManifest(BaseModel):
+    # ... alle bestehenden Felder ...
+    
+    # ── Versioning (Phase 4) ──
+    min_app_version: str = Field(
+        default="0.0.0",
+        description="Minimum LeoCRM version required (SemVer)"
+    )
+    
+    # ── Marketplace (Phase 5) ──
+    author: str = Field(default="", max_length=200, description="Plugin author name")
+    author_email: str = Field(default="", max_length=200, description="Author contact email")
+    homepage: str = Field(default="", max_length=500, description="Plugin homepage URL")

+    marketplace_tags: list[str] = Field(default_factory=list, description="Marketplace category tags")
+    price: float = Field(default=0.0, ge=0.0, description="Price (0 = free)")
+    
+    # ── Hooks (Phase 2) ──
+    hooks: list[str] = Field(
+        default_factory=list,
+        description="Hook names this plugin registers (e.g. 'contact.before_create')"
+    )
+    
+    # ── Contracts (Phase 1) ──
+    contract_version: str = Field(
+        default="1.0.0",
+        description="Contract API version this plugin exposes"
+    )
+```
+
+### 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 |

+| 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
+
+---
+
+## Zeitplan
+
+```
+Woche 1 (Tag 1-5):  Phase 1 — Contracts (Teil 1: contracts.py + Imports)
+Woche 2 (Tag 6-8):  Phase 1 — Contracts (Teil 2: Deaktivierung + Tests)
+         (Tag 9-10): Phase 2 — Hooks/Filters-System
+Woche 3 (Tag 11):   Phase 3 — Plugin-Isolation
+         (Tag 12-14): Phase 4 — Plugin-Versioning
+Woche 4 (Tag 15-19): Phase 5 — Marketplace-Vorbereitung
+Woche 5 (Tag 20-22): Phase 6 — Manifest-Anpassung & Konsolidierung
+         (Tag 23):   Puffer / Bugfixes / Doku
+```
+
+### Abhängigkeiten
+```
+Phase 1 (Contracts) ──→ Phase 3 (Isolation: Linting braucht Contracts als Ausnahme)
+         │
+         └──→ Phase 2 (Hooks: unabhängig, kann parallel)
+         │
+         └──→ Phase 4 (Versioning: braucht Contracts für min_app_version)
+                  │
+                  └──→ Phase 5 (Marketplace: braucht alles)
+                           │
+                           └──→ Phase 6 (Manifest: braucht Phase 4 + 5 Felder)
+```
+
+### Parallelisierungsmöglichkeiten
+- Phase 1 und Phase 2 können **parallel** laufen (verschiedene Entwickler)
+- Phase 3 kann erst nach Phase 1 starten
+- Phase 4 kann nach Phase 1 starten
+- Phase 5 kann erst nach Phase 1+4 starten
+- Phase 6 kann erst nach Phase 4+5 starten (braucht deren Manifest-Felder)
+

+
+## Risiken
+
+| Risiko | Wahrscheinlichkeit | Auswirkung | Mitigation |
+|---|---|---|---|
+| Contract-Refactoring bricht bestehende Funktionalität | Mittel | Hoch | Tests nach jedem Plugin, schrittweise Migration |
+| Hooks/Filters verändern Core-Verhalten | Niedrig | Mittel | Tests für alle Hook-Punkte, Priority-System |
+| Externe Plugin-Discovery hat Sicherheitslücken | Mittel | Hoch | Signatur-Validierung, Quarantine, Allowlist |
+| SemVer-Parse-Fehler bei bestehenden Versionen | Niedrig | Niedrig | Fallback auf String-Vergleich |
+| Rollback-Migrationen löschen Daten | Mittel | Hoch | Bestätigungs-Prompt, Backup vor Rollback |
+
+---

+Revision ID: 0044
+Revises: 0043
+Created: 2026-07-26
+
+This migration:
+1. Re-discovers ALL tenant-scoped tables and ensures RLS is enabled
+   with FORCE + WITH CHECK (covers tables added after migration 0028).
+2. Creates a separate ``crm_runtime`` role with NOSUPERUSER and
+   NOBYPASSRLS so the application cannot bypass RLS.
+3. Grants only DML permissions (SELECT/INSERT/UPDATE/DELETE) to
+   ``crm_runtime`` on all tenant-scoped tables.
+
+IMPORTANT: After this migration, the application's DATABASE_URL must
+use ``crm_runtime`` (not the superuser) for API and worker containers.
+Migration/DDL operations continue to use the owner user (crm_user).

+Revision ID: 0045
+Revises: 0044
+Created: 2026-07-26
+
+Problem:
+  Migrations 0021 and 0027 were retroactively rewritten to be safer
+  (rename old tables, INSERT ... SELECT, preserve *_old tables).
+  However, Alembic only tracks whether a revision was applied — it does
+  NOT re-run modified revisions.  Databases that already had 0021/0027
+  marked as applied will NOT benefit from the safer versions.
+
+This migration:
+  1. Detects *_old tables (left behind by the rewritten 0021).
+  2. Compares row counts between *_old and current tables.
+  3. Migrates any missing rows from *_old to the current tables.
+  4. Logs discrepancies and aborts on data integrity issues.
+  5. Also repairs entity_type='company' → 'contact' (from rewritten 0027).
+
+Safe to run on fresh installations (no *_old tables → no-op).

+This is the core function that ALL routes use to filter queries based on

+Usage:

+        ...
+
+Architecture:
+- System admin → no filter (sees everything)
+- Non-admin → filter by: owner_id = user OR owner_id IS NULL OR shared via entity_permissions
