+# 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     |
+| HIGH     | 8     |
+| 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

+## 11. Resource C — crm-worker (Background Worker)
+
+The crm-worker runs the ARQ background worker and scheduler in a separate
+container, using the same Docker image as crm-app but with a different
+entrypoint (`/app/worker.sh` instead of `/app/prestart.sh`).
+
+### Setup in Coolify UI
+
+1. In the same project/environment as crm-app, **+ Add → Application →
+   Public/Private Repository**.
+2. Fill in:
+   - **Git repository**: same as crm-app (`https://forgejo.media-on.de/Leopoldadmin/leocrm.git`)
+   - **Branch**: `main`
+   - **Build pack**: `Dockerfile`
+   - **Dockerfile location**: `Dockerfile` (same image)
+   - **Port**: `8000` (not used, but Coolify requires a port)
+   - **Custom Entrypoint**: `/app/worker.sh`
+3. Click **Deploy** once to create the resource.
+4. Note the **Application UUID**.
+
+### Environment variables (on the crm-worker resource)
+
+Set the same variables as crm-app, except:
+
+| Key | Value | Notes |
+|-----|-------|-------|
+| `DATABASE_URL` | same as crm-app | |
+| `REDIS_URL` | same as crm-app | |
+| `SECRET_KEY` | same as crm-app | |
+| `ENVIRONMENT` | `production` | |
+| `LOG_LEVEL` | `INFO` | |
+| `STORAGE_PATH` | `/data/storage` | |
+
+No domain is needed — the worker is not publicly accessible.
+
+### Healthcheck (Coolify side)
+
+- **Healthcheck path**: `/api/v1/health` (not used by worker, but Coolify requires one)
+- Alternatively, use a custom healthcheck command:
+  `pgrep -f "arq app.core.worker.WorkerSettings" || exit 1`
+
+### Scaling
+
+To scale the worker horizontally, deploy multiple crm-worker instances.
+Cron jobs use a Redis-based distributed lock (`SET NX` with TTL) so only
+one replica executes each scheduled job.

+# LeoCRM Deployment
+
+## Quick Start
+
+### Option A: Coolify (empfohlen für Produktion)
+
+```bash
+# Einmalig: Umgebungsvariablen setzen
+export COOLIFY_API_TOKEN="dein-token"
+export COOLIFY_APP_UUID="deine-app-uuid"
+
+# Deploy
+python scripts/deploy.py
+
+# Redeploy (ohne Neubuild)
+python scripts/deploy.py --skip-build
+```
+
+Das Script macht automatisch:
+1. Coolify Build & Deploy triggern
+2. Persistent Volume in Coolify DB konfigurieren (automatisch, portabel)
+3. Auf healthy Container warten
+4. RLS auf allen Tenant-Tabellen sicherstellen
+5. DB-Migrationen verifizieren
+6. Worker-Container starten
+7. App-Health verifizieren
+8. Domain-Erreichbarkeit prüfen
+
+**Funktioniert auf jeder Coolify-Instanz. Bei mehreren Apps. Bei Erst-Deploy und Redeploy.**
+
+### Option B: Docker Compose (lokal / ohne Coolify)
+
+```bash
+# .env.docker erstellen
+cp .env.docker.example .env.docker
+$EDITOR .env.docker  # SECRET_KEY, POSTGRES_PASSWORD, etc. ausfüllen
+
+# Starten (alle 4 Container: Postgres, Redis, App, Worker)
+docker compose --env-file .env.docker up --build -d
+
+# Health check
+curl http://localhost:8000/api/v1/health
+
+# Stoppen
+docker compose down
+```
+
+**Container:**
+- `crm-postgres` — PostgreSQL 16 mit pgvector
+- `crm-redis` — Redis 7
+- `crm-app` — FastAPI API Server
+- `crm-worker` — ARQ Background Worker
+
+Alle mit persistenten Volumes. Kein Datenverlust bei Redeploy.
+
+## Voraussetzungen
+
+- Python 3.12+
+- Docker & Docker Compose (für Option B)
+- Coolify v4+ (für Option A)
+- SSH-Zugang zum Server (für Option A)
+
+## Umgebungsvariablen
+
+Siehe `.env.example` für alle Variablen. Wichtigste:
+
+| Variable | Pflicht | Default | Beschreibung |
+|---|---|---|---|
+| `DATABASE_URL` | Ja | — | PostgreSQL Connection String |
+| `REDIS_URL` | Ja | — | Redis Connection String |
+| `SECRET_KEY` | Ja | — | Mindestens 32 Zeichen |
+| `ENVIRONMENT` | Nein | `development` | `production` oder `development` |
+| `SESSION_COOKIE_SECURE` | Nein | `true` | In Production muss `true` |
+| `STORAGE_PATH` | Nein | `/data/storage` | Datei-Upload-Pfad |
+| `STORAGE_BACKEND` | Nein | `local` | `local` oder `s3` |
+
+## S3 Storage (optional)
+
+Die App unterstützt S3-kompatiblen Storage. Setze:
+```bash
+STORAGE_BACKEND=s3
+S3_ENDPOINT=https://s3.example.com
+S3_BUCKET=leocrm
+S3_ACCESS_KEY=...
+S3_SECRET_KEY=...
+```
+
+## Test- vs. Produktionsumgebung
+
+**Test:**
+```bash
+python scripts/deploy.py --environment test
+```
+Eigene Coolify-App, eigene DB, eigene Domain (`crm-test.media-on.de`).
+
+**Produktion:**
+```bash
+python scripts/deploy.py --environment production
+```
+
+## Troubleshooting
+
+**Container nicht healthy:**
+```bash
+docker logs <container-name> --tail 50
+```
+
+**Migration fehlgeschlagen:**
+```bash
+docker exec <container> alembic upgrade head
+```
+
+**RLS nicht aktiv:**
+```bash
+python scripts/deploy.py --migrate-only
+```
+
+**Worker nicht gestartet:**
+```bash
+python scripts/deploy.py --skip-build  # startet Worker automatisch
+```
+
+## Backup & Restore
+
+### Backup (PostgreSQL)
+
+```bash
+# Full DB backup (run on the host or via docker exec)
+docker exec crm-postgres pg_dump -U crm_user -Fc crm_db > backup_$(date +%Y%m%d_%H%M%S).dump
+
+# Backup mit Custom-Format (komprimiert, parallel restore-fähig)
+docker exec crm-postgres pg_dump -U crm_user -Fc -Z 9 crm_db > backup_$(date +%Y%m%d).dump
+```
+
+### Backup (Redis — Sessions/Queues)
+
+```bash
+# Redis RDB Snapshot
+docker exec crm-redis redis-cli -a "$REDIS_PASSWORD" SAVE
+docker cp crm-redis:/data/dump.rdb redis_backup_$(date +%Y%m%d).rdb
+```
+
+### Backup (File Storage)
+
+```bash
+# Local storage volume
+docker run --rm -v leocrm-fix_storage:/data -v $(pwd):/backup alpine \
+  tar czf /backup/storage_$(date +%Y%m%d).tar.gz /data
+```
+
+### Restore (PostgreSQL)
+
+```bash
+# Stop app containers
+docker compose stop crm-app crm-worker
+
+# Restore DB
+docker exec -i crm-postgres pg_restore -U crm_user -d crm_db --clean < backup_20260726.dump
+
+# Restart app
+docker compose start crm-app crm-worker
+```
+
+### Automatisierte Backups (Cron)
+
+```bash
+# /etc/cron.d/leocrm-backup
+0 2 * * * root docker exec crm-postgres pg_dump -U crm_user -Fc crm_db > /backups/leocrm_$(date +\%Y\%m\%d).dump
+0 3 * * * root find /backups -name 'leocrm_*.dump' -mtime +30 -delete
+```
+
+**Empfehlung:** Tägliche DB-Backups, 30 Tage Aufbewahrung. Storage-Backup wöchentlich.

+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
+
+---
+

+
+## ✅ Erledigte Fixes (22 von 24 Items komplett)
+
+Die folgenden Items wurden bei der Überprüfung am 2026-07-26 als erledigt bestätigt:
+
+| 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` |
+| P2-4 | SPA Path-Traversal | `app/main.py` — `os.path.abspath` Check + `".." in full_path` Blocking |
+

+
+## ⏳ Offene Items
+
+### P0-7: App von öffentlicher Domain nehmen
+
+**Status:** Operational — nicht aus Code verifizierbar
+
+**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 ✅) sind bereits behoben
+3. Alternativ: VPN/Tunnel-Zugang statt öffentliche Domain
+
+**Aufwand:** 30 Minuten
+
+---
+
+### P2-2: Plugin-Cross-Imports reduzieren
+
+**Status:** Offen — 228 direkte Cross-Imports zwischen Plugins
+
+**Problem:** 228 direkte `from app.plugins.builtins` Imports zwischen Plugins. Automatisierung importiert Modelle/Services von Kommunikation, Mail, Kalender. Verteilter Monolith ohne Modulgrenzen.
+
+**Maßnahme:**
+1. Öffentliche Schnittstellen (Contracts) für jedes Modul definieren
+2. Direkte Imports fremder Plugin-Modelle verbieten
+3. Kommunikation nur über Events oder öffentliche Service-API
+4. CI-Check: keine direkten Cross-Plugin-Imports
+
+**Aufwand:** 1-2 Wochen

+
+## ⚠️ Audit-Korrekturen (26.07.2026 02:17)
+
+### Korrektur 1: Permissions Management UI — ENTHALTEN IN SettingsRoles.tsx
+**Vorher:** Plan sagte "keine Verwaltungs-Seite um Permissions pro Rolle zu konfigurieren"
+**Tatsächlich:** `SettingsRoles.tsx` (531 Zeilen) hat VOLLSTÄNDIGE Permission-Verwaltung:
+- ✅ Grant permissions (Checkboxen gruppiert nach system/plugin)
+- ✅ Denied permissions (explizite Verweigern-Liste)
+- ✅ Field-level permissions (pro Modul/Feld Sensitivität)
+- ✅ Rollen erstellen/bearbeiten mit Permission-Zuweisung
+- ✅ DMS `ShareDialog.tsx` nutzt bereits File-Permissions API (grant/revoke/share-link)
+**Folge:** Feature 8 entfällt. Keine neue Permission-UI nötig.
+
+### Korrektur 2: Import/Export — Export-Route fehlt DEFINITIV
+**Vorher:** Plan sagte "falls Export fehlt"
+**Tatsächlich:** `export_contacts_csv()` Service-Funktion existiert, aber KEINE Route in `import_export.py`. Nur `/import` und `/import/preview` sind registriert. Export muss als Route hinzugefügt werden.
+
+### Korrektur 3: Activity Timeline — ActivityFeed existiert bereits
+**Vorher:** Plan sagte "Dashboard hat ActivityFeed aber nur statisch"
+**Tatsächlich:** Dashboard nutzt `ActivityFeed` mit Daten aus Audit-API. Komponente ist wiederverwendbar. Es fehlt nur eine eigenständige Seite mit Filterung/Pagination.
+
+### Korrektur 4: DMS ShareDialog — File Permissions bereits integriert
+**Vorher:** Plan sah `FilePermissionDialog` als neue Komponente vor
+**Tatsächlich:** `ShareDialog.tsx` (11KB) existiert bereits und nutzt `fetchFilePermissions`, `grantPermission`, `revokePermission`, `createShareLink`, `revokeShareLink` aus `permissions.ts`.
+

+
+## Übersicht: 14 verbleibende Features in 4 Phasen
+
+| Phase | Features | Priorität | Geschätzter Aufwand |

+**Gesamtaufwand:** ~11-14 Entwicklungstage (1 Feature entfallen)
+
+---
+
+## Architektur-Grundsätze (für alle Features)
+
+### Frontend-Konventionen
+- **Routing:** Lazy-loaded in `frontend/src/routes/index.tsx`, explizite Routes (nicht PluginRouteRenderer)
+- **API-Clients:** In `frontend/src/api/<name>.ts`, verwenden `apiGet/apiPost/apiPatch/apiDelete` aus `client.ts`
+- **Hooks:** React Query (`useQuery`/`useMutation`) mit Query-Key-Invalidierung
+- **UI:** Tailwind CSS, `clsx` für Klassen, `lucide-react` für Icons
+- **i18n:** `useTranslation()` mit `t('key')`, Keys in `frontend/src/i18n/`
+- **Sidebar:** Plugin-Manifeste liefern Menu-Items via `usePluginStore` — neue Pages brauchen Plugin-Manifest-Einträge
+- **Settings:** Hardcoded nav items in `Settings.tsx` + plugin settings_pages
+- **Error Handling:** `ErrorBoundary` wrappt alle Routes
+
+### Backend-Konventionen
+- **Routes:** `app/routes/<name>.py`, registriert in `app/main.py`
+- **Services:** `app/services/<name>_service.py`
+- **Models:** `app/models/<name>.py`, Migrationen in `alembic/versions/`
+- **Schemas:** `app/schemas/<name>.py` (Pydantic)
+- **Permissions:** `require_permission('plugin:action')` Dependency
+- **Events:** `event_bus.publish()` für System-Events
+
+---
+
+## Phase 1 — Kritisch für CRM-Betrieb
+
+### 1.1 Workflows UI

+
+## Entfallenes Feature
+
+### ~~Permissions Management UI~~ — BEREITS VORHANDEN
+- `SettingsRoles.tsx` (531 Zeilen) hat vollständige Permission-Verwaltung
+- `ShareDialog.tsx` (11KB) nutzt File-Permissions API
+- `roles.ts` API-Client hat `usePermissions()`, `useRoles()`, `useCreateRole()`, `useUpdateRole()`, `useDeleteRole()`
+- Backend `/roles/permissions` liefert alle System+Plugin-Permissions
+- Backend Roles-CRUD erlaubt Permission-Zuweisung (grant/deny/field-level)

+**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)

+**Wichtig:** Jede Phase ist unabhängig funktionsfähig. Das System läuft nach jeder Phase ohne Einschränkungen weiter.
+
+---
+
+## 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.

+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

+```
+
+| # | 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

+### 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)."""

+- ✅ 0 direkte Cross-Plugin-Imports (automatisch erzwungen)
+
+---
+
+## 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

+    
+    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)

+    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."""

+
+**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)

+            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.

+- ✅ 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)

+
+### 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 |

+
+**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 ──

+    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 |

+Problem:
+  Migrations 0021 and 0027 were retroactively rewritten to be safer

+  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).
