 # T06: Mail Plugin Backend — Implementation Briefing
 ## Task
 Implement the complete Mail Plugin as a built-in plugin under `app/plugins/builtins/mail/`.
 ## Requirements (F-MAIL-01 bis F-MAIL-19)
 - F-MAIL-01: Standard-Ordner (Posteingang, Postausgang, Entwürfe, Spam) + IMAP-Sync
 - F-MAIL-02: E-Mail schreiben, antworten, weiterleiten (HTML-Editor, SMTP)
 - F-MAIL-03: Volltext-Suche über Mails (body_tsv, FTS)
 - F-MAIL-04: Anhänge (hochladen, herunterladen, DMS-Link)
 - F-MAIL-05: Threading (Konversationen gruppieren, References/In-Reply-To)
 - F-MAIL-06: Vorlagen/Templates (Platzhalter-Substitution)
 - F-MAIL-07: Filter/Regeln (Condition → Action: move/label/flag/forward)
 - F-MAIL-08: Abwesenheitsnotiz (Auto-Reply, dedup via vacation_sent_log)
 - F-MAIL-09: Labels/Flags (Stern, Wichtig, Custom Labels, farbig)
 - F-MAIL-10: Kontakt-Verknüpfung (auto aus Email-Adressen, manuell)
 - F-MAIL-11: Kalender-Integration (Termin aus Mail erstellen)
 - F-MAIL-12: PGP-Verschlüsselung (Key-Import, encrypt/decrypt, contact public keys)
 - F-MAIL-13: Signaturen (pro User, pro Postfach, HTML-Content)
 - F-MAIL-14: Mehrere Postfächer (IMAP/SMTP pro User konfigurierbar)
 - F-MAIL-15: Geteilte Postfächer (Gruppen-Postfach, Seen-By-Tracking)
 - F-MAIL-16: Stellvertretung (Delegate access: read/full)
 - F-MAIL-17: Sende-Berechtigungen (wer darf als Gruppe senden)
 - F-MAIL-18: Postfach-Konfiguration (IMAP/SMTP, AES-256 encrypted credentials, Verbindungstest)
 - F-MAIL-19: Mail-Ordner verwalten (Erstellen, Umbenennen, Löschen, IMAP-Sync)
 ## Acceptance Criteria (40 ACs)
 See task_graph.json T06.acceptance_criteria — ALL must pass.
 ## Architecture
 - Plugin Pattern: Follow `app/plugins/builtins/dms/` structure exactly
 - Files to create:
  - `app/plugins/builtins/mail/__init__.py`
  - `app/plugins/builtins/mail/plugin.py` (MailPlugin class, PluginManifest)
  - `app/plugins/builtins/mail/models.py` (14+ SQLAlchemy models)
  - `app/plugins/builtins/mail/schemas.py` (Pydantic schemas for all entities)
  - `app/plugins/builtins/mail/routes.py` (APIRouter with all endpoints)
  - `app/plugins/builtins/mail/services.py` (Service layer: IMAP sync, SMTP send, rules, vacation, PGP)
  - `app/plugins/builtins/mail/migrations/0001_initial.sql` (DB migration)
  - `tests/test_mail.py` (Test all 40 ACs)
 ## Models Required
 mail_accounts, mail_folders, mails, mail_attachments, mail_labels, mail_label_assignments, mail_rules, mail_templates, mail_signatures, vacation_sent_log, mail_seen_by, mail_account_delegates, mail_account_send_permissions, pgp_keys, contact_pgp_keys
 ## Key Technical Details
 - AES-256 encryption for mail account passwords (use `cryptography` package)
 - IMAP sync as ARQ background job (arq already in requirements.txt)
 - body_tsv column with PostgreSQL FTS (tsvector)
 - PGP via `pgpy` or `python-gnupg` package
 - HTML sanitization (no script tags) — use `bleach` or `nh3`
 - Plugin manifest: name="mail", dependencies=["permissions"] or []
 - Routes prefix: `/api/v1/mail`
 - Follow existing test pattern from `tests/test_dms.py` (use authed_client, ORIGIN_HEADER)
 - All routes need `get_current_user` dependency from `app.deps`
 ## Test Spec
 - Test file: `tests/test_mail.py`
 - Run: `cd /a0/usr/workdir/dev-projects/leocrm && python -m pytest tests/test_mail.py -v --tb=short`
 - Coverage: `python -m pytest tests/test_mail.py --cov=app/plugins/builtins/mail --cov-report=term-missing`
 - Coverage target: 80%
 - Follow `tests/test_dms.py` pattern: conftest fixtures (authed_client, ORIGIN_HEADER, login_client)
 ## Dependencies to Add (requirements.txt)
 - `cryptography>=42.0` (AES-256 encryption)
 - `pgpy>=0.6.0` or `python-gnupg>=0.5` (PGP)
 - `bleach>=6.0` or `nh3>=0.2` (HTML sanitization)
 - `aiosmtplib>=3.0` (async SMTP)
 - `aioimaplib>=1.0` (async IMAP)
 ## Forbidden Patterns
 - No synchronous IMAP/SMTP in route handlers — use async or ARQ jobs
 - No plaintext password storage — AES-256 encryption mandatory
 - No raw HTML in API responses without sanitization
 - No credential values in any API response
 - No `time.sleep()` in tests — use `asyncio.sleep()` or mocking
 ## Existing Code References
 - Plugin base class: `app/plugins/base.py` → BasePlugin
 - Plugin manifest: `app/plugins/manifest.py` → PluginManifest, PluginRouteDef
 - DMS plugin (pattern to follow): `app/plugins/builtins/dms/`
 - Calendar plugin (pattern to follow): `app/plugins/builtins/calendar/`
 - Test pattern: `tests/test_dms.py`, `tests/test_calendar.py`
 - DB deps: `app/core/db.py` → get_db
 - Auth deps: `app/deps.py` → get_current_user
 - Test fixtures: `tests/conftest.py` → authed_client, ORIGIN_HEADER, login_client
 ## Estimated Size
 - ~800 lines code (models + schemas + routes + services + plugin + migration)
 - ~400+ lines tests

 # T08a: Frontend DMS + Tags + Permissions UI — Implementation Briefing
 ## Task
 Implement frontend UI for DMS plugin (file browser, upload, preview, share, trash), Tags UI (assign, bulk, tag cloud), and Permissions UI (share links, permission display).
 ## Requirements
 - F-DMS-01–07: DMS file browser, folder tree, upload, preview, share, trash, search
 - F-FILEUI-01–06: File UI components (dropzone, preview modal, share dialog, bulk actions, trash view)
 - F-TAG-01–04: Tags UI (assign, bulk assign, tag cloud, tag picker)
 - F-PERM-03–05: Permissions UI (share links, permission display)
 - F-LINK-01–05: Entity links UI
 ## Acceptance Criteria (12 ACs)
 1. DMS route /dms renders file browser with folder tree + file grid
 2. DMS upload: drag file to dropzone → upload progress → file appears in list
 3. DMS file preview modal opens with PDF.js for PDF files
 4. DMS share dialog: select user/group, set permission, share created
 5. DMS public share link: copy button generates URL, optional password+expiry fields
 6. DMS bulk select → bulk-move or bulk-delete actions appear
 7. DMS trash view: deleted files list, restore button per file
 8. Mail: shared mailbox selector (DO NOT IMPLEMENT — belongs to T08c)
 9. Tags: tag picker on company/contact detail → assign/unassign
 10. Tags: bulk select entities → bulk-tag dialog
 11. Plugin deactivate → plugin route+menu-item disappear from SPA
 12. Plugin activate → plugin route+menu-item appear in SPA

 # T10: Monitoring, Performance, Documentation & Environment Config — Implementation Briefing
 ## Task
 Three modules in one task: (1) Monitoring & Alerting, (2) Performance, (3) Documentation.
 ## Acceptance Criteria (18 ACs)
 ### Monitoring (AC1-6)
 1. GET /api/v1/health → 200 + JSON with status, checks.database, checks.redis, checks.storage, checks.worker
 2. GET /api/v1/health mit DB down → 200 + status=degraded, checks.database.status=down
 3. GET /api/v1/metrics → 200 + text/plain Prometheus format (admin only, 403 for non-admin)
 4. Prometheus metrics include leocrm_http_requests_total, leocrm_db_pool_connections, leocrm_arq_jobs_total
 5. Structured JSON log entry for API request: {timestamp, level, event, method, path, status, duration_ms, tenant_id}
 6. Error log includes stacktrace and request context
 ### Performance (AC7-12)
 7. scripts/seed_perf_data.py --count 200000 → creates 200k contacts in test DB
 8. GET /api/v1/contacts?page=1&page_size=25 with 200k records → response time <500ms
 9. GET /api/v1/contacts?search=Mueller with 200k records → response time <500ms
 10. page_size > 100 → 422 (max page_size enforced)
 11. CSV export >1000 records → ARQ background job started → notification on completion
 12. Streaming CSV export: GET /api/v1/contacts/export?format=csv → text/csv stream (not buffered)
 ### Documentation (AC13-18)
 13. README.md exists with Setup-Anleitung (dev + prod), API section, links to admin-guide
 14. Swagger UI available at /api/v1/docs (FastAPI auto-gen)

 16. docs/api-overview.md exists with endpoint summary table
 17. .env.example file exists with all required variables documented (database, redis, smtp, storage, secret_key)
 18. Environment-specific config: dev, test, prod profiles documented in docs/admin-guide.md
 ## Existing Code References
 - **Health endpoint:** app/routes/health.py (simple, needs extension)

 - **Contacts route:** app/routes/contacts.py (has search param, pagination)
 - **Companies route:** app/routes/companies.py (has search, pagination, export)
 - **README.md:** exists (basic, needs update with prod setup, API section, admin-guide link)
 - **.env.example:** exists (good coverage, may need SMTP/storage additions)
 - **docs/:** only requirements docs, needs admin-guide.md + api-overview.md
 - **Docker:** docker-compose.yml + Dockerfile exist
 - **Coolify:** COOLIFY_SETUP.md exists
 ## Files to Create

 - Docs check: `test -f README.md && test -f docs/admin-guide.md && test -f docs/api-overview.md && echo 'Docs OK'`
 - Coverage target: 80%
 - Follow existing test pattern from tests/test_health.py or tests/test_companies.py
 ## Forbidden Patterns
 - No blocking I/O in async health check — use async DB ping
 - No credentials in logs or metrics
 - No unbounded pagination — max 100 per page enforced
 - No buffering large CSV exports — use StreamingResponse
 - No hardcoded config — use app/config.py settings
 ## Estimated Size
 - ~500 lines code (monitoring + scripts + docs)
 - ~300+ lines tests

 # 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

 ## 2026-07-25 19:07 — P2-1: Unified Contact Model normalisieren — COMPLETE
 - **6 files changed** (5 modified + 1 new migration)
 - **Migration 0039_contact_normalize.py**: surfix→suffix rename, Float→Numeric(5,2) for 6 discount columns with CHECK constraints (0-100), JSON→JSONB for contacts.custom and contactpersons.custom, partial unique indexes on (tenant_id, code) and (tenant_id, accounting_code)
 - **Model**: surfix→suffix, Float→Numeric(5,2), JSON→JSONB, UniqueConstraint added, Decimal import
 - **Schema**: surfix→suffix (3x), float→Decimal (18x), Decimal import
 - **Services**: contact_service.py (3x surfix→suffix), dedup_service.py (1x surfix→suffix)
 - **Frontend**: unifiedContacts.ts surfix→suffix in UnifiedContact interface
 - **Checks**: py_compile OK, alembic heads → 0039_contact_normalize (single head), comprehensive grep confirms zero surfix in source code

 ## 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.

 # 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

 ## ⏳ 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 |
 |-------|----------|-----------|---------------------|
 | **1 — Kritisch** | Workflows UI, Dedup/Merge UI, Import/Export UI, Print/PDF | CRM-Kern | ~4-5 Tage |
 | **2 — Wichtig** | Tags UI, Custom Fields UI, Notifications Dropdown | Tagesgeschäft | ~2.5-3 Tage |
 | **3 — Nice-to-have** | Saved Filters UI, Entity History UI, Activity Timeline, API Docs Link | Produktivität | ~1.5-2 Tage |
 | **4 — Backend+Frontend** | Webhooks, Backup/Restore UI, Onboarding/Tutorial | Erweiterungen | ~3-4 Tage |
 **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

 ## Deployment-Strategie
 ### Nach jeder Phase:
 1. Frontend Build: `cd frontend && npm run build`
 2. Git commit + push
 3. Coolify Auto-Deploy
 4. Verifikation im Browser
 ## Abhängigkeiten
 ```
 1.1 Workflows UI ← keine (API ready)
 1.2 Dedup/Merge UI ← keine (API ready)
 1.3 Import/Export UI ← Backend Export-Route hinzufügen (Service existiert)
 1.4 Print/PDF ← keine
 2.1 Tags UI ← keine (API ready)
 2.2 Custom Fields UI ← Backend CRUD + Migration (neu)
 2.3 Notifications Bell ← keine (API ready)
 3.1 Saved Filters ← keine (API ready)
 3.2 Entity History ← keine (API ready)
 3.3 Activity Timeline ← Audit-API ggf. erweitern (Pagination)
 3.4 API Docs Link ← keine
 4.1 Webhooks ← Backend komplett neu + Migration
 4.2 Backup/Restore ← Backend komplett neu + Migration
 4.3 Onboarding ← User-Preferences API ggf. erweitern
 ```
 ## Risiko-Bewertung
 | Feature | Risiko | Grund |
 |---------|--------|-------|
 | Workflows UI | Mittel | Komplexe Step-Editor UI |
 | Custom Fields UI | Hoch | Backend-Ergänzung + dynamisches Rendering |
 | Webhooks | Hoch | Backend komplett neu, Security (HMAC, Retry) |
 | Backup/Restore | Hoch | Datenverlust-Risiko bei Fehlern |
 | Import/Export | Mittel | Backend Export-Route fehlt, Datei-Handling |
 | Alle anderen | Niedrig | API existiert, nur 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)

 # LeoCRM — Master Plan: Umbau & Vollendung
 **Erstellt:** 2026-07-22
 **Status:** Draft — zur Freigabe
 **Letzte Revision:** 2026-07-22 (gründliche Überprüfung nach Code-Tiefenanalyse)
 ---
 ## Ausgangslage
 ### Was bereits gut ist
 - Backend: ~35.800 Zeilen, 12 Plugins, Multi-Tenant mit RLS, Rate Limiting, Audit Log
 - Unified Contact Model: **BEREITS implementiert** (Migration 0021) — Contact mit type='company'|'person', ContactPerson als 1:N child (wie Rentman)
 - Frontend: ~30.000 Zeilen, 27 Pages, 70 Components, i18n DE/EN, TanStack Query, TipTap
 - Tests: ~17.300 Zeilen Backend-Tests, 38 Vitest-Dateien
 - Docker: Multi-Stage-Build (Frontend+Backend in einem Container)
 - Datenbank: PostgreSQL 16 als separater docker-compose Service
 - WebSocket-Infrastruktur: Bereits im `kommunikation` Plugin vorhanden (`/api/v1/comm/ws`) — kann als Referenz für KI-UI-Steuerung dienen
 ### Was fehlt oder nicht stimmt
 - Frontend nutzt unified Contact Model nicht vollständig (keine Contact-Detail-Route, ContactPerson-Verwaltung fehlt in UI)
 - **'company' als entity_type ist in 6 Plugins verankert** — muss zu 'contact' vereinheitlicht werden
 - Plugin-UI-System fehlt (hartkodierte Routes statt dynamische Registry)
 - Code-Splitting fehlt (alle 27 Pages im Main Bundle)
 - E2E Tests fehlen komplett
 - KI-UI-Steuerung fehlt
 - Virtual Scrolling fehlt
 - React Hook Form + Zod nicht überall
 - hooks.ts ist Monolith (1.298 Zeilen)
 - Fehlende Dependencies (lucide-react, date-fns)
 - Plugin-Richtlinien fehlen
 ### Wichtige Unterscheidung: 'company' hat zwei Bedeutungen
 1. **entity_type='company'** in Plugins (entity_links, calendar, tags, mail) → referenziert eine Firma als Entität → **MUSS zu 'contact' werden**
 2. **system_settings.company_*** Felder (company_name, company_street etc.) → CRM-Besitzer-Firmeninfo für Rechnungen → **BLEIBT wie es ist**
 3. **CalendarType='company'** → Kalender-Typ (Firmenkalender) → kann bleiben oder zu 'organization' umbenannt werden (kosmetisch)
 ---
 ## Architektur-Entscheidungen (freigegeben 2026-07-22)
 1. **KI-UI-Steuerung:** Keine Mausbewegung nötig. KI muss zu Kontakten springen und einen Kontakt öffnen können. Die UI muss das Ergebnis zeigen — Kontaktliste und spezieller Kontakt ausgewählt. Implementierungsweg (WebSocket, postMessage, etc.) ist offen, Hauptsache das Ergebnis wird in der UI sichtbar.
 2. **Company-Routes:** Komplett entfernen. Keine deprecated-Routes, keine Redirects. Kontakte wie in Rentman — ein unified Contact-Modell, kein separates Company-Modell mehr. **Alle Plugin-Referenzen auf entity_type='company' müssen zu 'contact' migriert werden.**
 3. **PostgreSQL:** Aktuell egal (Coolify-managed oder docker-compose). Reine Docker-Lösung soll später möglich sein. Keine Code-Änderung nötig — nur Konfiguration.
 4. **S3-Storage:** Provider egal. Wichtig ist nur dass die Architektur es später ermöglicht. Bereits vorbereitet in config.py (STORAGE_BACKEND=s3).
 ---
 ## Phasen-Plan
 ### PHASE 0: Vorbereitung & Cleanup
 **Ziel:** Codebasis bereinigen, Dependencies installieren, veraltete Dokumente aktualisieren
 | # | Aufgabe | Aufwand | Details |
 |---|---|---|---|
 | 0.1 | Veraltete Planungsdokumente aktualisieren | 2h | `codebase-vs-requirements.md` neu schreiben (beschreibt alten Stand), `architecture.md` um Implementation-Status erweitern, `security-review-phase2.md` um 'Resolved' Markierungen ergänzen |
 | 0.2 | `lucide-react` installieren + Icons migrieren | 4h | Inline SVGs durch lucide-react Icons ersetzen. Konsistente Icon-Bibliothek. |
 | 0.3 | `date-fns` installieren + Datum-Formatierung | 3h | Alle `toLocaleDateString()` etc. durch date-fns ersetzen. Konsistente Datum-Formatierung. |
 | 0.4 | `hooks.ts` aufteilen | 3h | 1.298 Zeilen aufteilen in `api/auth.ts`, `api/contacts.ts`, `api/settings.ts` etc. Generische Hooks bleiben in `hooks.ts`. Company-Hooks werden in Phase 1 entfernt, nicht aufgeteilt. |
 | 0.5 | Store-Verzeichnis konsolidieren | 1h | `store/` und `stores/` zusammenführen. |
 | 0.6 | Frontend-Bestandsanalyse als Dokument speichern | 1h | `frontend-gap-analysis.md` mit vollständiger Analyse. |
 | 0.7 | UI-Design-Richtlinien erstellen | 6h | `docs/ui-design-guidelines.md` basierend auf bestehenden Plugin-Patterns (siehe unten). |
 | 0.8 | Theme-Customization Backend | 4h | `system_settings` um Theme-Felder erweitern (primary_color, accent_color, font_family, border_radius). Neue Alembic-Migration. API-Endpoints zum Lesen/Schreiben der Theme-Settings. |
 | 0.9 | Theme-Customization Frontend | 6h | `SettingsTheme.tsx` Seite mit Color-Picker, Font-Auswahl, Live-Preview. Tailwind-CSS-Variablen dynamisch aus API-Settings überschreiben. Dark-Mode-Toggle. Theme wird beim App-Start geladen und angewendet. |
 | 0.10 | RBAC-Audit & Plugin-Permissions nachrüsten | 6h | 4 Plugins haben `permissions=[]` (calendar, dms, entity_links, tags) → keine Rechte-Prüfung! Pro Plugin passende Permissions definieren und in Manifest eintragen. Routes mit `require_permission()` absichern. Siehe Details unten. |
 | 0.11 | LiteLLM-Cleanup & alte llm_client.py migrieren | 3h | LiteLLM ist **BEREITS** in ai_assistant und ai_proactive integriert (`litellm.acompletion()`). Nur die alte `llm_client.py` (Copilot) nutzt noch httpx direkt. Diese auf LiteLLM umstellen oder entfernen. System-Prompt in llm_client.py referenziert noch `/api/v1/companies` → auf Contacts umstellen. |
 | 0.12 | KI-Agent-Framework in Plugin-Richtlinien dokumentieren | 2h | PydanticAI + tool_registry existieren bereits. In `docs/plugin-development-guide.md` dokumentieren: Wie Plugins KI-Agenten, Tools und LLM-Funktionen nutzen. Plugin-Manifest um `agent_capabilities` Feld erweitern. |
 | 0.13 | Heartbeat konfigurierbar machen | 3h | Heartbeat-Intervall, Aktivierung, Ziel-Room in ProactiveSettings (DB) speichern. Settings-UI für Heartbeat-Konfiguration. |
 | 0.14 | Unified Search: Field-Level RBAC nachrüsten | 4h | Search-Provider prüfen aktuell KEINE Feld-Level-Permissions. Nutzer mit `search:read` sieht alle Felder. Provider müssen `resolved_perms` prüfen und `hidden` Felder ausblenden. `to_search_result()` um Permission-Filter ergänzen. |
 | 0.15 | Undo/History-System für CRUD-Operationen | 8h | Globale Undo-History: Jede CRUD-Aktion (Create/Update/Delete) wird mit Snapshot in `entity_history` Tabelle gespeichert. User kann Änderungen rückgängig machen oder zu früherer Version zurückkehren. Nutzt bestehenden Audit-Log als Basis. Frontend: Undo-Button + History-Viewer pro Entity. |
 | 0.16 | Storage Backend implementieren (S3-Support) | 8h | Architecture.md beschreibt abstract StorageBackend (local/S3), aber **existiert NICHT im Code**. Attachments nutzen hardcoded `/data/uploads`. Storage-Klasse erstellen: `LocalStorage` + `S3Storage`. Config um `STORAGE_BACKEND`, `S3_ENDPOINT`, `S3_BUCKET`, `S3_ACCESS_KEY`, `S3_SECRET_KEY` erweitern. DMS und Attachments auf Storage-Backend umstellen. .env.example um S3-Variablen ergänzen. |
 | 0.17 | Import/Export an unified Contact Model anpassen | 4h | Import/Export nutzt alte Feldnamen (`first_name`, `last_name`, `mobile`, `position`, `department`). Auf unified Contact-Felder umstellen (`firstname`, `surname`, `phone_1`, `email_1`, etc.). Company-Import auf Contact mit type='company' umstellen. |
 | 0.18 | .gitignore & Config-Cleanup | 2h | `.gitignore` hat `webui/` statt `frontend/` — frontend/node_modules und frontend/dist werden nicht ignoriert! Korrigieren. `python-jose` (JWT) aus requirements.txt entfernen — Code nutzt Session-Auth. `pyproject.toml` Python-Version auf 3.12 aktualisieren. `.env.docker.example` JWT-Variablen entfernen. **.env aus Git entfernen** (ist committet aber sollte nicht sein). `dump.rdb` und `test.txt` aus Repo löschen. `frontend/dist/` aus Git entfernen (sollte nicht committet sein). |
 | 0.19 | Mail-Salt Security-Fix | 2h | `mail/services.py` hat hardcoded salt `b"leocrm-mail-salt"` für Passwort-Verschlüsselung. Salt sollte random pro Account sein. Fix: Random salt generieren und mit encrypted_password zusammen speichern. DB-Migration für bestehende Accounts. |
 | 0.20 | AGPL-Lizenzen durch kommerziell nutzbare Alternativen ersetzen | 6h | **PyMuPDF** (AGPL-3.0) → ersetzen durch `pypdf` (BSD). Text-Extraktion in unified_search anpassen. **OnlyOffice** (AGPL-3.0) → ersetzen durch **Collabora Online** (LGPL/MPL). DMS Edit-Sessions auf Collabora umstellen. `requirements.txt`, `Dockerfile`, `docker-compose.yml`, `architecture.md` aktualisieren. DMS Plugin `OnlyOfficeConfig` → `CollaboraConfig`. Frontend DMS-Komponenten anpassen. Lizenz-Datei (`LICENSE`) und `THIRD_PARTY_LICENSES.md` erstellen. |
 **Phase 0 Gesamt: ~77h**
 ### UI-Design-Richtlinien (Task 0.7)
 Basierend auf Analyse der bestehenden Plugins (Calendar, Mail, DMS, Contacts):
 **Layout-Patterns:**
 - **3-Spalten-Explorer-Layout** (Tree | Liste/Explorer | Detail) — verwendet von Calendar, Mail, DMS
 - **ResizablePanel** für drag-to-resize Spalten — bereits implementiert
 - **PluginToolbar** für Plugin-Aktionen (oben) — bereits implementiert
 - **Modal** für Formulare (Create/Edit/Delete-Bestätigung) — bereits implementiert
 - **EmptyState** für leere Listen — bereits implementiert
 - **LoadingState/Skeleton** für Lade-Zustände — bereits implementiert
 **Farbsystem (Tailwind Design Tokens):**
 - `primary` (Blau #2563eb) — Hauptaktionen, aktive Zustände
 - `secondary` (Slate #64748b) — Text, Borders, Hintergründe
 - `accent` (Fuchsia #d946ef) — Hervorhebungen, Info-Badges
 - `danger` (Rot #dc2626) — Löschen, Fehler
 - `warning` (Amber #f59e0b) — Warnungen
 - `success` (Grün #16a34a) — Erfolg, Bestätigungen
 - Jede Farbe mit 50-900 Schattierungen
 - **Dark Mode** via `darkMode: 'class'` — CSS-Variablen in `:root` und `.dark`
 **Typografie:**
 - Font: `Inter` (system-ui fallback)
 - Mono: `JetBrains Mono` für Code/Daten
 - Größen: xs (0.75rem) bis 4xl (2.25rem)
 - Zeilenhöhen definiert pro Größe
 **Komponenten-Konventionen:**
 - **Button**: 4 Varianten (primary/secondary/danger/ghost), 3 Größen (sm/md/lg), `min-h-touch` (44px), `focus-visible:ring-2`
 - **Card**: Titel + Beschreibung + Actions (header), Body, optional Footer (bg-secondary-50)
 - **Badge**: 7 Varianten (default/primary/success/warning/danger/info/secondary), optional dot
 - **Input/Select**: `focus-ring` Klasse, `border-secondary-200`, `rounded-md`
 - **Modal**: `size` prop (sm/md/lg/xl), `ConfirmDialog` für Bestätigungen
 - **Table/DataGrid**: TanStack Table, ARIA-labels auf sortierbare Headers
 - **Toast**: `useToast()` Hook für Benachrichtigungen
 **Spacing & Layout:**
 - Standard-Padding: `px-6 py-4` (Card body), `p-4` (Panel)
 - Gap: `gap-2` (Buttons), `gap-4` (Sections), `gap-6` (Columns)
 - Border-Radius: `rounded-md` (0.5rem) Standard, `rounded-lg` (0.75rem) für Cards
 - Shadow: `shadow-sm` (Cards), `shadow-md` (Dropdowns), `shadow-lg` (Modals)
 **Accessibility (bereits implementiert):**
 - `focus-ring` Klasse: `focus-visible:ring-2 focus-visible:ring-primary-500`
 - `btn-touch` Klasse: `min-h-touch min-w-touch` (44px)
 - `sr-only` und `sr-only-focusable` Klassen
 - `prefers-reduced-motion` Media Query
 - `aria-hidden="true"` auf dekorativen SVGs
 - `aria-label` auf interaktiven Elementen ohne sichtbaren Text
 **Plugin-UI-Patterns (für neue Plugins):**
 - Jede Plugin-Seite folgt dem 3-Spalten-Layout (wenn anwendbar)
 - PluginToolbar für Aktionen (Create, Import, Export, etc.)
 - Plugin-Settings als eigene Settings-Sub-Seite
 - Plugin-Detail-Tabs (z.B. "Dateien" bei Contact-Detail)
 - Konsistente EmptyState-Komponente wenn keine Daten
 - Konsistente LoadingState/Skeleton-Komponente beim Laden
 - Toast für Erfolg/Fehler-Meldungen nach Aktionen
 - ConfirmDialog vor destruktiven Aktionen
 **Was im Design-Guide dokumentiert wird:**
 1. Farbsystem mit Verwendungsregeln (wann welche Farbe)
 2. Typografie-Hierarchie (Überschriften, Body-Text, Labels)
 3. Layout-Patterns (3-Spalten, Modal, Settings-Tree)
 4. Komponenten-Verwendung (welche Komponente für was)
 5. Spacing & Sizing Konventionen
 6. Accessibility-Regeln
 7. Dark-Mode-Regeln
 8. Plugin-UI-Patterns für neue Plugins
 9. Do's & Don'ts
 10. Code-Beispiele aus bestehenden Plugins
 ### RBAC-Audit & Plugin-Permissions (Task 0.10)
 **Problem:** 4 Plugins haben `permissions=[]` im Manifest → keine Rechte-Prüfung auf ihren Routes:
 | Plugin | Aktuell | Muss definiert werden |
 |---|---|---|
 | **calendar** | `permissions=[]` | `calendar:read`, `calendar:write`, `calendar:delete`, `calendar:share`, `calendar:admin` |
 | **dms** | `permissions=[]` | `dms:read`, `dms:write`, `dms:delete`, `dms:share`, `dms:admin` |
 | **entity_links** | `permissions=[]` | `entity_links:read`, `entity_links:write`, `entity_links:delete` |
 | **tags** | `permissions=[]` | `tags:read`, `tags:write`, `tags:delete`, `tags:admin` |
 **Was zu tun ist:**
 1. Pro Plugin passende Permissions im Manifest definieren
 2. Alle Plugin-Routes mit `require_permission()` absichern
 3. Permission-Registry registriert Plugin-Permissions automatisch beim Aktivieren
 4. Admin kann Permissions in Rollen-Editor zuweisen
 5. Tests: User ohne Permission → 403, User mit Permission → 200
 **Zusätzlich in Phase 1 (Permission-Registry-Cleanup):**
 - `companies:read/write/delete` aus `CORE_PERMISSIONS` entfernen (wird zu `contacts:read/write/delete`)
 - `CORE_FIELD_DEFINITIONS` aktualisieren: alte Felder (`first_name`, `last_name`, `mobile`, `position`, `department`, `linkedin_url`) durch unified Contact-Felder ersetzen (`firstname`, `surname`, `phone_1`, `email_1`, etc.)
 - `companies` Field-Definitions entfernen
 ### LiteLLM-Integration (Task 0.11)
 **Problem:** Aktuelle `llm_client.py` spricht nur OpenAI-compatible API direkt via httpx. Keine Unterstützung für Anthropic, Google, lokale Modelle etc.
 **Lösung:** LiteLLM als unified LLM-Interface integrieren.
 **Was LiteLLM bietet:**
 - 100+ LLM-Provider über eine einheitliche API (OpenAI, Anthropic, Google, Azure, AWS Bedrock, Ollama, etc.)
 - Konsistente Request/Response-Formate
 - Streaming-Support
 - Fallback/Routing-Regeln
 - Cost-Tracking
 - Rate-Limiting
 **Was zu tun ist:**
 1. `litellm` als Python-Dependency hinzufügen
 2. `llm_client.py` auf LiteLLM umstellen: `litellm.acompletion()` statt direktem httpx-Call
 3. Konfiguration via Env-Vars: `AI_MODEL`, `AI_API_KEY`, `AI_API_BASE` (bleiben gleich), plus `AI_PROVIDER` (neu: openai/anthropic/google/ollama/etc.)
 4. AI Assistant Plugin nutzt LiteLLM für Multi-Provider-Support
 5. AI Proactive Plugin nutzt LiteLLM für Suggestions
 6. Zukünftige Plugins können LiteLLM einfach nutzen — einheitliches Interface
 7. Mock-Mode für Tests beibehalten (wenn kein API-Key gesetzt)
 8. Plugin-Entwickler-Richtlinien: Wie man LiteLLM in neuen Plugins nutzt
 **Architektur:**
 ```
 Plugin (ai_assistant, ai_proactive, zukünftige)
    ↓
 LiteLLM (unified LLM interface)
    ↓
 Provider (OpenAI, Anthropic, Google, Ollama, ...)
 ```
 **Vorteil für zukünftige Plugins:**
 - Ein Plugin kann LLM-Funktionen nutzen ohne sich um den Provider zu kümmern
 - Admin kann Provider in Settings konfigurieren
 - KI-Modelle können ausgetauscht werden ohne Code-Änderung
 ---
 ### PHASE 1: Unified Contact Model — Vollendung (Backend + Frontend)
 **Ziel:** 'company' als separates Konzept komplett entfernen. Alles ist 'contact' mit type='company'|'person'. Wie Rentman.
 #### 1A: Backend — Company-Routes & Services entfernen
 | # | Aufgabe | Aufwand | Details |
 |---|---|---|---|
 | 1.1 | `app/routes/companies.py` entfernen | 1h | 303 Zeilen. Router aus `main.py`/`routes/__init__.py` austragen. |

 | # | Aufgabe | Aufwand | Details |
 |---|---|---|---|
 | 1.9 | **entity_links Plugin** aktualisieren | 4h | `entity_type` Pattern von `^(company|contact)$` → `^contact$`. `company_router` entfernen. `on_company_deleted` → `on_contact_deleted`. Event `company.deleted` → `contact.deleted`. DB-Migration: bestehende EntityLinks mit entity_type='company' auf 'contact' migrieren. |
 | 1.10 | **unified_search Plugin** aktualisieren | 6h | `CompanySearchProvider` → wird zu `ContactSearchProvider` oder bleibt als Provider für type='company' Kontakte. `index_company` → `index_contact`. Events `company.created/updated` → `contact.created/updated`. `search_engine.py` Mapping `"company" → "contacts"` anpassen. `jobs.py` aktualisieren. |
 | 1.11 | **calendar Plugin** aktualisieren | 3h | `entity_type` Pattern von `^(company|contact)$` → `^contact$`. CalendarEntryLink entity_type anpassen. DB-Migration: bestehende Links migrieren. CalendarType='company' kann bleiben (Kalender-Typ, nicht Entity-Referenz). |
 | 1.12 | **tags Plugin** aktualisieren | 3h | `entity_type` Pattern von `^(company|contact|file|folder)$` → `^(contact|file|folder)$`. DB-Migration: bestehende Tag-Assignments mit entity_type='company' auf 'contact' migrieren. |
 | 1.13 | **mail Plugin** aktualisieren | 4h | `mail.company_id` Spalte → `mail.contact_id` (DB-Migration). Routes, Schemas, Services aktualisieren. `company_id` Referenzen in Frontend-API-Modul. |
 | 1.14 | **test_sample Plugin** aktualisieren | 1h | `company.created` Event → `contact.created`. Test-Plugin ist Referenz für Plugin-Entwicklung. |
 | 1.15 | **Event-Namen vereinheitlichen** | 2h | Alle `company.created/updated/deleted` Events → `contact.created/updated/deleted`. Event-Publisher in contact_service.py prüfen. |
 | 1.16 | **DB-Migration: entity_type 'company' → 'contact'** | 3h | Alembic-Migration: UPDATE entity_links SET entity_type='contact' WHERE entity_type='company'. UPDATE tag_assignments SET entity_type='contact' WHERE entity_type='company'. UPDATE calendar_entry_links SET entity_type='contact' WHERE entity_type='company'.

 | 1.20 | **conftest.py aktualisieren** | 2h | `conftest.py` importiert `Company` und `CompanyContact` aus alten Modellen. Auf unified Contact Model umstellen. Test-Fixtures anpassen. |
 **1B Gesamt: ~33h**
 #### 1C: Frontend — Unified Contact UI
 | # | Aufgabe | Aufwand | Details |
 |---|---|---|---|
 | 1.18 | Contact-Detail-Route hinzufügen | 2h | Route `/contacts/:id` in `routes/index.tsx`. `ContactDetail.tsx` (372 Zeilen) existiert bereits als Komponente. |
 | 1.19 | ContactList mit Type-Filter (company/person) | 4h | `ContactsList.tsx` (445 Zeilen) um Type-Filter erweitern. Tabs oder Toggle: "Alle | Firmen | Personen". |
 | 1.20 | ContactDetail um ContactPerson-Verwaltung erweitern | 8h | Bei type='company': Ansprechpartner-Liste, Ansprechpartner hinzufügen/bearbeiten/löschen. ContactPerson API-Hooks in Frontend. |
 | 1.21 | ContactEditModal für beide Types | 6h | Formular je nach type unterschiedlich: company → name, person → firstname/surname. Adressen (mailing/visit/invoice). |
 | 1.22 | Company-Hooks aus `hooks.ts` entfernen | 2h | `useCompanies`, `useCompany`, `useCreateCompany`, `useUpdateCompany`, `useDeleteCompany`, `useCompanyExport`, `useCompanyImport` entfernen. Company-Interface entfernen. |
 | 1.23 | Frontend Type-Definitions aktualisieren | 2h | `calendar.ts`: entity_type 'company' → 'contact'. `tags.ts`: EntityType 'company' entfernen. `search.ts`: type 'company' → 'contact'. `mail.ts`: company_id → contact_id. |
 | 1.24 | Dashboard.tsx aktualisieren | 1h | `useUnifiedContacts(1, 1, undefined, 'company')` → `useUnifiedContacts(1, 1, undefined, 'company')` (type-Filter bleibt, ist jetzt Contact type nicht Company entity). |
 | 1.25 | GlobalSearchResults.tsx aktualisieren | 2h | Search result type 'company' → 'contact'. Grouping, Icons, Labels anpassen. |
 | 1.26 | ContactFolderTree in ContactList integrieren | 4h | Ordner-Baum links, Kontaktliste rechts. Drag & Drop Kontakte in Ordner. |
 | 1.27 | React Hook Form + Zod in ContactEditModal | 3h | Strukturierte Validierung für alle Contact-Felder. |
 | 1.28 | Frontend-Tests aktualisieren | 4h | Tests für Contact-Detail, ContactEditModal, ContactPerson-Verwaltung. Company-Test-Referenzen entfernen. |
 **1C Gesamt: ~38h**
 **Phase 1 Gesamt: ~81h** (vorher 33h — unterschätzt um 48h!)
 ---
 ### PHASE 2: Code-Splitting & Performance
 **Ziel:** Frontend lädt nur was nötig ist. Virtual Scrolling überall.
 | # | Aufgabe | Aufwand | Details |
 |---|---|---|---|
 | 2.1 | React.lazy + Suspense für alle Routes | 4h | Alle Page-Imports in `routes/index.tsx` auf `React.lazy()` umstellen. `<Suspense>` mit Loading-Fallback. |

 | 2.7 | Bundle-Analyse & Optimierung | 2h | `vite-bundle-visualizer` prüfen, manuelle Chunks für große Dependencies. |
 **Phase 2 Gesamt: ~25h**
 ---
 ### PHASE 3: Plugin-UI-System (WordPress-Style)
 **Ziel:** Dynamisches Plugin-UI-Loading. Plugins registrieren sich selbst.
 | # | Aufgabe | Aufwand | Details |
 |---|---|---|---|
 | 3.1 | Plugin-Manifest-Frontend-Endpoint | 4h | Backend-Endpoint `GET /api/v1/plugins/active-manifests` liefert alle aktiven Plugin-Manifeste mit UI-Definitionen (routes, menu_items, detail_tabs, settings_pages, dashboard_widgets). |
 | 3.2 | `PluginRegistry.tsx` erstellen | 8h | Fetcht aktive Plugin-Manifeste beim App-Start. Registriert Routes, Menu-Items, Detail-Tabs, Settings-Pages dynamisch. |
 | 3.3 | `PluginLoader.tsx` erstellen | 6h | Lazy-loaded Plugin-Komponenten via `React.lazy()`. Suspense-Boundaries pro Plugin. Error-Boundary falls Plugin nicht lädt. |
 | 3.4 | Sidebar dynamisch aus Plugin-Manifesten | 4h | Sidebar rendert Menu-Items aus Plugin-Registry statt hartkodierte Items. |
 | 3.5 | Settings-Baum dynamisch aus Plugin-Manifesten | 4h | Settings-Pages werden dynamisch aus Plugin-Manifesten generiert. |

 └─────────────────────────────────────────────┘
 ```
 | # | Aufgabe | Aufwand | Details |
 |---|---|---|---|
 | 3.11 | Plugin-Manifest um Agent/Automation-Felder erweitern | 4h | Manifest um `agent_definitions`, `automation_templates`, `cron_jobs`, `heartbeat_configs` erweitern. Plugins deklarieren was sie mitbringen. |
 | 3.12 | Cron-Scheduler Backend | 6h | ARQ-basierter Scheduler für periodische Tasks. Cron-Expressions (z.B. `0 8 * * *` = täglich 8 Uhr). Scheduler liest aktive Cron-Jobs aus DB und enqueued sie. Ersetzt hartkodierten Heartbeat. |
 | 3.13 | Workflow-Timeout-Worker | 4h | ARQ-Job der regelmäßig Workflow-Instanzen mit abgelaufenem `timeout_at` prüft. Bei Timeout: Status auf `cancelled`, Notification an Initiator. |
 | 3.14 | Agent Builder Backend | 8h | API für Agent-Definitionen: Name, Beschreibung, LLM-Modell, Tools (aus tool_registry), System-Prompt, Heartbeat-Intervall, Proaktiv/Reaktiv-Modus. Agent-Definitionen in DB gespeichert. |
 | 3.15 | Automation Builder Backend | 6h | API für Automation-Definitionen: Trigger (Event/Schedule/Manual), Conditions, Actions (API-Call/Notification/Workflow-Start). Automation-Definitionen in DB gespeichert. |
 | 3.16 | Automation Execution Engine | 6h | Engine die Automations ausführt: Event-Trigger → Conditions prüfen → Actions ausführen. Nutzt Event-Bus für Event-Trigger, Cron-Scheduler für Schedule-Trigger. |
 | 3.17 | Agent Runner | 8h | Führt Agenten aus: Proaktiv (Heartbeat-getriggert, sammelt Kontext, generiert Vorschläge) oder Reaktiv (auf Event/Message, reagiert). Nutzt LiteLLM + tool_registry + PydanticAI. |
 | 3.18 | Automation & Agents UI — Automation Builder | 8h | Visueller Builder für Automations: Trigger auswählen, Conditions definieren, Actions zusammenstellen. Drag & Drop oder Form-basiert. Live-Preview. |
 | 3.19 | Automation & Agents UI — Agent Builder | 8h | Visueller Builder für Agenten: Name, Modell, Tools, System-Prompt, Heartbeat. Test-Run Button. Agent-Liste mit Status (aktiv/inaktiv). |
 | 3.20 | Automation & Agents UI — Dashboard | 4h | Übersicht: Aktive Automations, Aktive Agenten, Letzte Ausführungen, Logs, Fehler. Heartbeat-Status pro Agent. |
 | 3.21 | Plugin-Beiträge registrieren | 4h | Wenn Plugin aktiviert wird: Agent-Definitionen, Automation-Templates, Cron-Jobs aus Manifest registrieren. Bei Deaktivierung: entfernen. |
 | 3.22 | Heartbeat-Verwaltung migrieren | 3h | Hartkodierten Heartbeat aus ai_proactive in Automation & Agents Plugin migrieren. Heartbeat wird zu einem konfigurierbaren Cron-Job. |
 | 3.23 | Settings für Automation & Agents | 3h | Einstellungen: Default-LLM-Modell für Agenten, Heartbeat-Default-Intervall, Max-Concurrent-Agents, Log-Level. |
 | 3.24 | Tests für Automation & Agents | 6h | Tests für Cron-Scheduler, Workflow-Timeouts, Agent Runner, Automation Engine, Plugin-Beiträge. |

 | 3.26 | RBAC für Automation & Agents | 3h | Permissions definieren: `automation:read`, `automation:write`, `automation:delete`, `automation:execute`, `agents:read`, `agents:write`, `agents:delete`, `agents:execute`. Nur Admin/Editor dürfen Agenten/Automations erstellen. |
 | 3.27 | Dry-Run / Test-Modus | 3h | Automations und Agenten können im Dry-Run getestet werden: Führt Conditions aus, zeigt was passieren würde, aber führt keine destruktiven Actions aus. Test-Button in Builder UI. |
 | 3.28 | Agent Rate-Limiting & Safety | 3h | Max-Ausführungen pro Agent pro Stunde. Max-Dauer pro Ausführung. Auto-Stop bei Endlosschleife (wenn Agent dieselbe Action 5x hintereinander ausführt). Budget-Limit pro Agent (LiteLLM Cost-Tracking). |
 | 3.29 | Plugin-Beitrags-Konfliktlösung | 2h | Wenn zwei Plugins denselben Agent-Namen/Templat-Namen mitbringen: Plugin-Name als Prefix (`mail.mail_sorter` statt `mail_sorter`). Dedup-Logik bei Registrierung. |
 | 3.30 | Agent-zu-Agent-Kommunikation | 8h | Agenten können Nachrichten an andere Agenten senden. Nutzt kommunikation Plugin-Infrastruktur (WebSocket, Rooms). Agent-Message-Router: Agent A sendet `{to: 'mail_sorter', message: 'Neuer Termin gefunden'}`. Empfänger-Agent reagiert. Agent-Chatrooms in Dashboard sichtbar. |
 | 3.31 | Versionshistorie für Agenten & Automations | 4h | Jede Änderung an Agent/Automation erstellt neue Version. Alte Versionen können wiederhergestellt werden. Versions-Diff in UI. `agent_versions` und `automation_versions` Tabellen. |
 | 3.32 | MiniApps: Plugin-MiniApps im Chat | 6h | **Bereits implementiert:** `MiniAppRegistry`, `MiniAppDef`, Routes (`GET /miniapps`, `POST /conversations/{id}/miniapps`), `MiniAppBlock.tsx` Frontend. **Was fehlt:** Plugin-Manifest um `miniapps` Feld erweitern (Plugins deklarieren welche MiniApps sie mitbringen). MiniApp-Builder UI (visuell MiniApps erstellen). MiniApp-Store in Settings. Dokumentation in Plugin-Entwickler-Richtlinien. |
 **Phase 3.5 Gesamt: ~105h**
 **Was Plugins mitbringen können:**
 - **Agent-Definitionen:** Ein Plugin kann vordefinierte Agenten mitbringen (z.B. Mail-Plugin bringt "E-Mail-Sortier-Agent" mit)
 - **Automation-Templates:** Ein Plugin kann Automation-Vorlagen mitbringen (z.B. Calendar-Plugin bringt "Terminerinnerung 24h vorher" mit)
 - **Cron-Jobs:** Ein Plugin kann periodische Tasks deklarieren (z.B. Mail-Plugin: "IMAP-Sync alle 15 Minuten")
 - **Heartbeat-Configs:** Ein Plugin kann Heartbeat-Konfigurationen mitbringen
 **Beispiel: Mail-Plugin bringt Agent mit**
 ```json
 {
  "agent_definitions": [{
    "name": "mail_sorter",
    "display_name": "E-Mail-Sortier-Assistent",
    "description": "Sortiert eingehende E-Mails automatisch nach Regeln",
    "model": "ollama/deepseek-v4-flash",
    "tools": ["mail.read", "mail.move", "mail.label"],
    "system_prompt": "Du sortierst E-Mails...",
    "mode": "reactive",
    "trigger_event": "mail.received"
  }]
 }
 ```
 **Beispiel: Calendar-Plugin bringt Automation mit**
 ```json
 {
  "automation_templates": [{
    "name": "appointment_reminder",
    "display_name": "Terminerinnerung 24h vorher",
    "trigger": {"type": "schedule", "cron": "0 8 * * *"},
    "conditions": [{"field": "entry.start_at", "operator": "lt", "value": "now + 24h"}],
    "actions": [{"type": "notification", "title": "Terminerinnerung", "body": "Morgen: ${entry.title}"}]
  }]
 }
 ```

 ## Zusammenfassung: Aufwandsschätzung (korrigiert)
 | Phase | Thema | Aufwand | Vorher | Änderung |
 |---|---|---|---|---|
 | 0 | Vorbereitung & Cleanup | ~77h | ~14h | **+63h** (Design, Theme, RBAC, LiteLLM, Search-RBAC, Undo, Storage, Import/Export, Config-Cleanup, Mail-Salt, PyMuPDF→pypdf, OnlyOffice→Collabora) |
 | 1 | Unified Contact (Backend+Frontend) | **~81h** | ~33h | **+48h** — Company-Referenzen in 6 Plugins + Permission-Registry + Addresses + conftest unterschätzt |
 | 2 | Code-Splitting & Performance | ~25h | ~25h | — |
 | 3 | Plugin-UI-System | ~58h | ~48h | +10h (Plugin-Install-System) |

 | | **GESAMT** | **~590h** | ~280h | **+310h** |
 ---
 ## Empfohlene Reihenfolge
 ```
 Phase 0 (Vorbereitung & Cleanup)
    ↓
 Phase 1 (Unified Contact — Backend+Frontend)  ← Core-CRM-Feature, größte Phase
    ↓
 Phase 2 (Code-Splitting & Performance)
    ↓
 Phase 3 (Plugin-UI-System)  ← WordPress-Style, nicht zu lange schieben
    ↓
 Phase 3.5 (Automation & Agents Plugin)  ← Agent Builder, Cron-Scheduler, Automation
    ↓
 Phase 4 (KI-UI-Steuerung)  ← Baut auf Plugin-System auf
    ↓
 Phase 5 (API-Vollständigkeit & Testbarkeit)  ← KI kann selbstständig testen
    ↓
 Phase 6 (React Hook Form + Zod)  ← Qualität
    ↓
 Phase 7 (Test-Vollendung)  ← Wartbarkeit für KI
 ```
 **Begründung der Reihenfolge:**
 1. Phase 0 zuerst: Dependencies und Cleanup als Fundament
 2. Phase 1 als Nächstes: Core-CRM-Feature (Contacts) muss vollständig sein. Größte Phase (~74h) weil 'company' überall im Code verankert ist.
 3. Phase 2: Code-Splitting ist schnell und bringt sofortige Performance-Verbesserung
 4. Phase 3: Plugin-UI-System — je früher desto besser, sonst wird Umbau später schwieriger
 5. Phase 4: KI-UI-Steuerung baut auf Plugin-System auf (dynamische Routes, Tabs etc.). Bestehende WebSocket-Infrastruktur aus kommunikation Plugin als Referenz.
 6. Phase 5: API-Vollständigkeit und E2E-Tests für KI-Wartbarkeit
 7. Phase 6+7: Qualität und Test-Vollendung
 ---
 ## Was bei der Überprüfung gefunden wurde
 ### Phase 1 Korrektur: +41h Aufwand
 Die ursprüngliche Schätzung von 33h für Phase 1 war **massiv unterschätzt**. Die gründliche Code-Analyse zeigte:
 **'company' als entity_type ist in 6 Plugins verankert:**
 - `entity_links`: entity_type Pattern, company_router, on_company_deleted Event-Handler
 - `unified_search`: CompanySearchProvider, index_company, company.created/updated Events, search_engine Mapping
 - `calendar`: entity_type Pattern für EntryLinks
 - `tags`: entity_type Pattern für Tag-Assignments
 - `mail`: company_id Spalte in mails Tabelle (DB-Migration nötig!)
 - `ai/action_mapper`: Company-Intents (create/delete/update/list)
 **Event-Namen müssen migriert werden:**
 - `company.created` → `contact.created`
 - `company.updated` → `contact.updated`
 - `company.deleted` → `contact.deleted`
 - Betroffen: unified_search, entity_links, workflows, test_sample, manifest.py
 **DB-Migration nötig:**
 - `entity_links.entity_type = 'company'` → `'contact'`
 - `tag_assignments.entity_type = 'company'` → `'contact'`
 - `calendar_entry_links.entity_type = 'company'` → `'contact'`
 - `mails.company_id` → `mails.contact_id` (Spalte umbenennen)
 **Was NICHT geändert wird:**
 - `system_settings.company_name`, `company_street` etc. → Das ist die CRM-Besitzer-Firmeninfo für Rechnungen. Bleibt wie es ist.
 - `CalendarType = 'company'` → Das ist ein Kalender-Typ (Firmenkalender), keine Entity-Referenz. Kann bleiben.
 ### Bestehende WebSocket-Infrastruktur
 Das `kommunikation` Plugin hat bereits eine vollständige WebSocket-Implementierung (`/api/v1/comm/ws`, `websocket_manager.py`). Diese kann als Referenz für die KI-UI-Steuerung (Phase 4) dienen — das spart Entwicklungszeit.
 ---
 ## KI-Wartbarkeit: Schlüssel-Anforderungen
 Damit ein KI-Agent die App selbstständig warten kann:
 1. **Vollständige API-Abdeckung:** Jede UI-Funktion per API steuerbar (Phase 5)
 2. **E2E-Tests:** Playwright-Tests die KI ausführen kann (Phase 5)
 3. **API-Health-Check:** Script das alle Endpunkte prüft (Phase 5)
 4. **Test-Runner:** Script das alle Tests ausführt und strukturiert reportet (Phase 7)
 5. **Deploy-Script:** KI kann Build erstellen, testen, deployen, rollback (Phase 5)
 6. **Plugin-Richtlinien:** Klare Vorgaben damit KI neue Plugins erstellen kann (Phase 3)
 7. **Dokumentation:** Aktuelle Architektur-Doku, API-Doku, Plugin-Guide (Phase 0+3+5)
 ---
 ## Nächste Schritte
 1. ✅ Nextcloud Backup erstellt (`/Backups/leocrm/leocrm-backup-20260722.bundle`)
 2. ✅ Plan gründlich überprüft und korrigiert (+45h)
 3. ⬜ Plan freigeben
 4. ⬜ Phase 0 starten
 5. ⬜ Planungsdokumente aktualisieren

 ## Agent-Anleitung: Wie ein KI-Agent diesen Plan umsetzt
 Dieser Plan ist so strukturiert dass ein KI-Agent (wie Agent Zero) ihn Task-für-Task umsetzen kann.
 ### Vorgehensweise pro Task
 1. **Task lesen:** Jeder Task hat Nummer, Aufwand, Beschreibung und Details
 2. **Code prüfen:** Vor der Umsetzung den aktuellen Code inspizieren (Dateien lesen, Abhängigkeiten prüfen)
 3. **Minimal-invasiv arbeiten:** Nur das ändern was der Task verlangt. Keine Refactoring-Touren.
 4. **Tests schreiben/aktualisieren:** Pro Task mindestens ein Test der die Änderung abdeckt
 5. **Commit:** Pro Task ein Git-Commit mit klarer Message (z.B. `Phase 0.2: install lucide-react and migrate icons`)
 6. **Verifizieren:** Nach jedem Task: Tests laufen, Build funktioniert, keine Regressionen
 ### Phasen-Reihenfolge ist verbindlich
 - Phase N+1 darf erst starten wenn Phase N abgeschlossen ist
 - Innerhalb einer Phase können Tasks parallel sein (z.B. 0.2 und 0.3 unabhängig)
 - Abhängigkeiten sind in den Task-Beschreibungen genannt
 ### Was ein Agent pro Task braucht
 - Dateipfade der zu ändernden Dateien (in Task-Beschreibung genannt)
 - Akzeptanzkriterien (in Task-Beschreibung genannt)
 - Test-Strategie (pro Task mindestens ein Test)
 - Git-Commit pro Task
 ### Plugin-Entwicklung
 Wenn ein Agent ein neues Plugin erstellt (z.B. Tasks-Plugin 5.21):
 1. Plugin-Verzeichnis in `app/plugins/builtins/<name>/` erstellen
 2. `plugin.py` mit Manifest (Name, Version, Dependencies, Routes, Permissions, Events)
 3. `models.py` mit SQLAlchemy Models (TenantMixin!)
 4. `schemas.py` mit Pydantic Schemas
 5. `routes.py` mit FastAPI Router (require_permission!)
 6. `services.py` mit Business-Logic
 7. Migration in `migrations/` Verzeichnis
 8. Frontend-Komponenten in `frontend/src/components/<name>/`
 9. Frontend-Seite in `frontend/src/pages/<Name>.tsx`
 10. API-Modul in `frontend/src/api/<name>.ts`
 11. Route in `frontend/src/routes/index.tsx` registrieren
 12. i18n-Keys in `frontend/src/i18n/locales/de.json` und `en.json`
 13. Tests in `tests/test_<name>.py` und `frontend/src/__tests__/<name>/`
 ### Plugin-Manifest-Format (für neue Plugins)
 ```python
 manifest = PluginManifest(
    name="my_plugin",
    version="1.0.0",
    display_name="My Plugin",
    description="What it does",
    dependencies=["permissions"],  # other plugins this depends on
    routes=[PluginRouteDef(path="/api/v1/my-plugin", module="...", router_attr="router")],
    events=["my.event"],  # events this plugin listens to
    migrations=["0001_initial.sql"],
    permissions=["my_plugin:read", "my_plugin:write"],
    is_core=False,
    # Neue Felder (nach Phase 3+3.5):
    # agent_definitions=[...],  # Agent-Templates
    # automation_templates=[...],  # Automation-Vorlagen
    # cron_jobs=[...],  # Periodische Tasks
    # custom_fields=[...],  # Custom Field Definitionen
    # dashboard_widgets=[...],  # Dashboard-Komponenten
    # miniapps=[...],  # MiniApp-Definitionen
 )
 ```
 ### Wichtige Regeln für Agent-Updates
 1. **Niemals Tests ändern** um sie grün zu bekommen — Code fixen nicht Tests anpassen
 2. **Niemals .env committen** — Secrets gehören nicht ins Repo
 3. **Jede DB-Änderung braucht Alembic-Migration** — keine manuellen SQL-Changes
 4. **Jede API-Route braucht RBAC** — `require_permission()` auf jedem Endpoint
 5. **Jedes Plugin-Model braucht TenantMixin** — tenant_id auf jeder Tabelle
 6. **Frontend-Änderungen brauchen i18n** — alle Texte in de.json und en.json
 7. **Pro Task ein Commit** — nicht mehrere Tasks in einem Commit
 8. **Nach jedem Task: Tests + Build verifizieren** — keine Regressionen
 9. **Nach jedem Task: Progress aktualisieren** — `PROGRESS.md` im Repo aktualisieren mit: Task-Nummer, Status (done/in-progress/blocked), Datum, was gemacht wurde, was als Nächstes ansteht. **Zwingend für jeden Agenten der am Plan arbeitet.**

 # LeoCRM Plugin-System — Kompletter Umbauplan
 **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)

 **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.
 **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)."""
 from __future__ import annotations
 import logging
 from collections import defaultdict
 from typing import Any, Callable
 logger = logging.getLogger(__name__)
 class HookRegistry:
    """Central registry for actions and filters.
    Actions: do_action('contact.before_create', data) — no return value
    Filters: result = apply_filters('contact.format_name', name) — returns modified value
    Priority: lower numbers run first (default=10).
    """
    _instance: HookRegistry | None = None
    def __new__(cls):
        if cls._instance is None:
            cls._instance = super().__new__(cls)
            cls._instance._actions: dict[str, list[tuple[int, Callable]]] = defaultdict(list)
            cls._instance._filters: dict[str, list[tuple[int, Callable]]] = defaultdict(list)
        return cls._instance
    def register_action(self, hook_name: str, callback: Callable, priority: int = 10) -> None:
        self._actions[hook_name].append((priority, callback))
        self._actions[hook_name].sort(key=lambda x: x[0])
    def register_filter(self, hook_name: str, callback: Callable, priority: int = 10) -> None:
        self._filters[hook_name].append((priority, callback))
        self._filters[hook_name].sort(key=lambda x: x[0])
    async def do_action(self, hook_name: str, *args, **kwargs) -> None:
        for _, callback in self._actions.get(hook_name, []):
            try:
                result = callback(*args, **kwargs)
                if hasattr(result, '__await__'):
                    await result
            except Exception:
                logger.exception("Error in action %s", hook_name)
    async def apply_filters(self, hook_name: str, value: Any, *args, **kwargs) -> Any:
        for _, callback in self._filters.get(hook_name, []):
            try:
                result = callback(value, *args, **kwargs)
                if hasattr(result, '__await__'):
                    result = await result
                value = result
            except Exception:
                logger.exception("Error in filter %s", hook_name)
        return value
    def unregister(self, hook_name: str, callback: Callable) -> None:
        self._actions[hook_name] = [(p, c) for p, c in self._actions.get(hook_name, []) if c != callback]
        self._filters[hook_name] = [(p, c) for p, c in self._filters.get(hook_name, []) if c != callback]
    def unregister_all(self, hook_name: str) -> None:
        self._actions.pop(hook_name, None)
        self._filters.pop(hook_name, None)
    def _reset_for_testing(self) -> None:
        self._actions.clear()
        self._filters.clear()
 def get_hook_registry() -> HookRegistry:
    return HookRegistry()
 async def do_action(hook_name: str, *args, **kwargs) -> None:
    await get_hook_registry().do_action(hook_name, *args, **kwargs)
 async def apply_filters(hook_name: str, value: Any, *args, **kwargs) -> Any:
    return await get_hook_registry().apply_filters(hook_name, value, *args, **kwargs)
 ```
 ### 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
 # In BasePlugin.on_deactivate:
 async def on_deactivate(self, db, service_container, event_bus) -> None:
    # Alle Hooks dieses Plugins abmelden
    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 |
 | 7 | mail_service | `mail.before_send` | Filter | E-Mail vor Versand modifizieren |
 | 8 | mail_service | `mail.after_send` | Action | Nach E-Mail-Versand |
 | 9 | calendar | `calendar.before_appointment` | Action | Vor Termin-Erstellung |
 | 10 | calendar | `calendar.after_appointment` | Action | Nach Termin-Erstellung |
 | 11 | auth_service | `auth.before_login` | Filter | Login-Daten validieren/modifizieren |
 | 12 | auth_service | `auth.after_login` | Action | Nach erfolgreichem Login |
 | 13 | user_service | `user.before_create` | Action | Vor User-Erstellung |
 | 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:
 - ✅ Linting-Regel aktiv
 - ✅ CI/CD prüft bei jedem Commit
 - ✅ 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
 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

 ## 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]
    agent_capabilities: list[str]
    menu_items: list[FrontendMenuItem]
    page_routes: list[FrontendPageRoute]
    detail_tabs: list[FrontendDetailTab]

    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")
    license: str = Field(default="MIT", max_length=50, description="License identifier")
    icon: str = Field(default="", description="Icon URL or emoji")
    screenshots: list[str] = Field(default_factory=list, description="Screenshot URLs for marketplace")
    changelog: str = Field(default="", description="Changelog URL or inline text")
    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 |

 | 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 |

 1. ✅ **0 direkte Cross-Plugin-Imports** (grep-verifiziert, linting-enforced)
 2. ✅ **Alle 16 Plugins haben contracts.py** mit klarer öffentlicher API
 3. ✅ **Contracts werden bei Deaktivierung abgemeldet**
 4. ✅ **Hooks/Filters-System** mit 15+ Hook-Punkten in Core-Services

+### Pagination
-└── README.md
+
 All list endpoints support pagination with `page` and `page_size` parameters.
 `page_size` is capped at **100** — values >100 return HTTP 422.
 ### CSV Export
 Contacts and companies support streaming CSV export via `/export?format=csv`.
 Uses `StreamingResponse` — does not buffer the entire file in memory.
 ### Swagger UI
 Interactive API documentation: http://localhost:8000/docs
 See [docs/api-overview.md](docs/api-overview.md) for the full endpoint summary.
 ## Monitoring
 ### Health Check
 ```bash
 curl http://localhost:8000/api/v1/health
 ```
 Returns JSON with overall status (`healthy`/`degraded`) and individual checks for
 `database`, `redis`, `storage`, and `worker`.
 ### Prometheus Metrics
 ```bash
 # Requires admin authentication
 curl -b "leocrm_session=<session>" http://localhost:8000/api/v1/metrics
 ```
 Available metrics:
 - `leocrm_http_requests_total` — Total HTTP requests
 - `leocrm_http_request_duration_seconds` — Request duration histogram
 - `leocrm_db_pool_connections` — Database connection pool size
 - `leocrm_arq_jobs_total` — Total ARQ background jobs
 ### Structured Logging
 LeoCRM uses `structlog` for structured JSON logging. All API requests are logged with:
 `timestamp`, `level`, `event`, `method`, `path`, `status`, `duration_ms`, `tenant_id`.
 ## Environment Profiles
 | Profile | `ENVIRONMENT` | Use Case |
 |---|---|---|
 | Development | `development` | Local dev (auto-reload, verbose logging) |
 | Testing | `testing` | Test suite (separate test DB, minimal logging) |
 | Production | `production` | Docker/Coolify deployment (JSON logging, secure cookies) |
 See [docs/admin-guide.md](docs/admin-guide.md#environment-profiles) for profile details.
 ## Testing
 ```bash
 # Run all tests
 pytest -v --tb=short
 # Run specific test suites
 pytest tests/test_monitoring.py tests/test_performance.py tests/test_health.py -v
 # Run with coverage
 pytest --cov=app --cov-report=term-missing
 # Run specific test file
 pytest tests/test_auth.py -v
 # Stop on first failure (for debugging)
 pytest -x
 ```
 ## Environment Variables
-| Variable | Required | Default | Description |
+See [.env.example](.env.example) for all variables and [docs/admin-guide.md](docs/admin-guide.md#environment-configuration) for detailed descriptions.
 |---|---|---|---|
 | `AUTH_SECRET` | ✅ | – | JWT signing secret (≥32 chars). Hard-fail if missing. |
 | `DATABASE_URL` | ❌ | `sqlite+aiosqlite:///./dev.db` | Async DB URL (aiosqlite or asyncpg) |
 | `JWT_ALGORITHM` | ❌ | `HS256` | JWT algorithm |
 | `JWT_EXPIRY_HOURS` | ❌ | `24` | Token lifetime |
 | `BCRYPT_ROUNDS` | ❌ | `12` | Password hashing cost |
 | `CORS_ORIGINS` | ❌ | `http://localhost:5500,http://localhost:8000` | Allowed origins (comma-separated, NO wildcards) |
 | `ENVIRONMENT` | ❌ | `development` | `development` or `production` |
 | `LOG_LEVEL` | ❌ | `INFO` | Python log level |
-## Architecture Decisions (ADR)
+### Key Variables
- **JWT Library**: `python-jose[cryptography]==3.3.0` (pattern reuse from wochenplaner)
+| Variable | Required | Description |
- **Database**: SQLite (aiosqlite) for dev, PostgreSQL (asyncpg) for prod
+|---|---|---|
- **Auth**: Stateless JWT in localStorage, bcrypt password hashing (12 rounds)
+| `DATABASE_URL` | ✅ | PostgreSQL async connection URL |
- **Security**: CORS whitelist (no wildcard), CSP middleware, no default admin user
+| `REDIS_URL` | ✅ | Redis connection URL |
- **Async**: All routers/services/DB operations are async (SQLAlchemy 2.0 + aiosqlite)
+| `SECRET_KEY` | ✅ | Secret key for signing (≥32 chars in prod) |
 | `CORS_ORIGINS` | ✅ | Comma-separated allowed origins (no wildcards) |
 | `ENVIRONMENT` | ❌ | `development` \| `testing` \| `production` |
 | `STORAGE_PATH` | ❌ | File storage path (default: `/tmp`) |
 | `SMTP_HOST` | ❌ | SMTP server hostname |
-See `/a0/.a0/02-architecture.md` Section 13 for full lockdown decisions.
+## Performance Testing
-## Deployment
+```bash
 # Seed 200k contacts for performance testing
 python scripts/seed_perf_data.py --count 200000
-See `/a0/.a0/03-task-graph.json` Phase 4d for Docker + Coolify setup (out of scope for Phase 4a).
+# Verify database indexes
 python scripts/check_indexes.py
 # Test pagination performance
 # GET /api/v1/contacts?page=1&page_size=25 — should be <500ms with 200k records
 ```

 """FORCE Row Level Security + WITH CHECK on all tenant-scoped tables.
 Revision ID: 0028_rls_force
 Revises: 0027_unify_company_to_contact
 Create Date: 2026-07-25
 This migration:
 1. Discovers all tables in the public schema that have a tenant_id column.
 2. ALTER TABLE ... FORCE ROW LEVEL SECURITY on each (ensures RLS applies to table owners too).
 3. Drops existing tenant_isolation policies and recreates them with both
   USING and WITH CHECK clauses so writes are also filtered by tenant.
 4. Covers core tables AND plugin tables (anything with tenant_id).
 Idempotent: safe to run multiple times.

 """User-Tenant model cleanup: single source of truth for membership and role.
 Revision ID: 0037_user_tenant_model
 Revises: 0036_cross_tenant_fk
 Create Date: 2026-07-25
 Changes:
 1. Make users.email globally unique (drop composite uq_users_tenant_email, add UNIQUE on email).
 2. Drop tenant_id, role, role_id columns from users table (with data migration to user_tenants).
 3. Add role column to user_tenants (built-in role string: admin/editor/viewer).
 4. Add status column to user_tenants (active/invited/disabled).
 5. Migrate existing data: copy users.tenant_id + users.role_id → user_tenants (if not already present).

 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).

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

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