 # T02: Company + Contact + Import/Export System
 ## Context
 - Project: LeoCRM (greenfield rewrite, Option C)
 - Repo: /a0/usr/workdir/dev-projects/leocrm
 - T01 COMPLETE: auth, multi-tenant, RBAC, sessions, audit, notifications all working
 - T01 commit: 7a7daf8 (pushed to Forgejo)
 - Tech: FastAPI + SQLAlchemy 2.0 async + PostgreSQL + Redis + Pydantic v2
 ## Existing T01 Code to Build On
 - `app/models/company.py` (40 lines) — Company model skeleton, needs Contact + CompanyContact models
 - `app/routes/companies.py` (210 lines) — Company CRUD skeleton, needs expansion + Contact routes
 - `app/schemas/company.py` (23 lines) — Company schema, needs Contact schemas
 - `app/core/db/__init__.py` — Engine, Session, Base, TenantMixin, set_tenant_context

 ## Files to Create/Modify
 ### New Files:
 - `app/models/contact.py` — Contact model + CompanyContact (N:M join table)
 - `app/schemas/contact.py` — Contact schemas (create/update/read/list)
 - `app/services/company_service.py` — Company CRUD + search + filter + pagination
 - `app/services/contact_service.py` — Contact CRUD + N:M linking
 - `app/services/import_export_service.py` — CSV import/export, XLSX export, dry-run preview
 - `app/routes/contacts.py` — Contact CRUD + N:M endpoints
 - `app/routes/import_export.py` — Import/export endpoints
 - `tests/test_companies.py` — Company CRUD + search + filter + export tests
 - `tests/test_contacts.py` — Contact CRUD + N:M + GDPR delete tests
 - `tests/test_import_export.py` — CSV import + preview + export tests
 ### Modify:
 - `app/models/company.py` — Add soft-delete (deleted_at), FTS tsvector, ensure TenantMixin
 - `app/routes/companies.py` — Expand to full CRUD + search + filter + export + N:M endpoints
 - `app/schemas/company.py` — Add pagination, search, filter schemas
 - `app/models/__init__.py` — Register Contact, CompanyContact
 - `app/routes/__init__.py` — Register contacts + import_export routers
 - `app/schemas/__init__.py` — Register contact schemas
 - `app/services/__init__.py` — Register new services
 - `tests/conftest.py` — Add contacts, company_contacts to TRUNCATE list
 - `alembic/versions/` — New migration for contacts + company_contacts + FTS indexes
 ## Dependencies to Install
 - `openpyxl>=3.1` — XLSX export (add to requirements.txt)
 ## Forbidden Patterns
 - NO JWT tokens (session-based auth from T01)
 - NO SQLite (PostgreSQL only)
 - NO wildcard CORS
 - NO raw SQL without tenant context (use set_config or ORM filtering)
 - NO hardcoded secrets
 - NO legacy code reuse
 - NO .test TLD emails (Pydantic v2 rejects — use .com)
 - NO `SET LOCAL` with bound params (use `SELECT set_config()` instead)
 - NO raising HTTPException in middleware (return JSONResponse)
 - NO POST without status_code=201
 ## Test Spec
 - Commands: `cd /a0/usr/workdir/dev-projects/leocrm && source venv/bin/activate && python -m pytest tests/test_companies.py tests/test_contacts.py tests/test_import_export.py -v --tb=short`
 - Coverage: `python -m pytest tests/test_companies.py tests/test_contacts.py tests/test_import_export.py --cov=app/routes/companies --cov=app/routes/contacts --cov=app/services --cov-report=term-missing`
 - Target: 85% for new modules
 - All 24 ACs must pass
 ## Token Rule
 - Use `text_editor:read` for MODIFY, `text_editor:write` for NEW, `code_execution_tool:terminal` for test runs
 - Reference files by path, not inline
 - Multi-file output: separate files, not one big file
 ## JSON Tool Examples
 Use this format for all tool calls:
 ```json
 {"tool_name":"text_editor","tool_args":{"action":"write","path":"/a0/usr/workdir/dev-projects/leocrm/app/models/contact.py","content":"..."}}
 ```

    name: str  # unique identifier
    version: str  # semver
    display_name: str
    description: str
    dependencies: list[str] = []  # other plugin names required
    routes: list[dict] = []  # route definitions
    events: list[str] = []  # event names to listen
    migrations: list[str] = []  # migration file names
    permissions: list[str] = []  # required permissions
 ```
 ## BasePlugin Abstract Class
 ```python
 class BasePlugin(ABC):
    manifest: PluginManifest
    async def on_install(self, db, service_container): ...
    async def on_activate(self, db, service_container, event_bus): ...

 /a0/usr/workdir/dev-projects/leocrm
 ## Context Files (READ FIRST)
 - `app/plugins/base.py` — BasePlugin abstract class
 - `app/plugins/manifest.py` — PluginManifest, PluginRouteDef
 - `app/plugins/builtins/tags/` — Reference plugin (subdirectory pattern)
 - `app/plugins/builtins/permissions/` — Already has share links + file permissions

 - `architecture.md` — Architecture decisions
 - `requirements.md` — F-DMS-*, F-FILE-*, F-FILEUI-* requirements
 ## Overview
 Implement DMS (Document Management System) plugin as `app/plugins/builtins/dms/`.
 ## Plugin Structure
 ```
 app/plugins/builtins/dms/
 ├── __init__.py          # Export DmsPlugin
 ├── plugin.py            # DmsPlugin(BasePlugin) with manifest
 ├── models.py            # Folder, File models
 ├── schemas.py           # Pydantic schemas for all endpoints
 ├── routes.py            # FastAPI APIRouter with all endpoints
 └── migrations/
    └── 0001_initial.sql # Create folders + files tables
 ```
 ## Models
 ### Folder
 - id (UUID, PK)
 - name (str, not null)
 - parent_id (UUID, FK to folders.id, nullable — null = root)
 - tenant_id (UUID, not null)
 - created_by (UUID, not null)
 - deleted_at (datetime, nullable — soft delete)
 - created_at, updated_at (TimestampMixin)
 - **Unique constraint**: (name, parent_id, tenant_id) where deleted_at IS NULL
 ### File
 - id (UUID, PK)
 - name (str, not null)
 - folder_id (UUID, FK to folders.id, nullable — null = root)
 - tenant_id (UUID, not null)
 - uploaded_by (UUID, not null)
 - mime_type (str, not null)
 - size_bytes (int, not null)
 - storage_path (str, not null — relative path on disk)
 - deleted_at (datetime, nullable — soft delete)
 - created_at, updated_at (TimestampMixin)
 ## File Storage
 - Store files at: `/data/dms/{tenant_id}/{file_uuid}` (configurable via plugin config)
 - Use `shutil.copyfileobj` for upload streaming
 - Generate UUID for filename on disk, keep original name in DB
 - Create directory with `os.makedirs(path, exist_ok=True)`
 ## Endpoints (19 ACs)
 ### Folders
 1. `GET /api/v1/dms/folders` → 200, folder tree (recursive tree structure)
   - Query param `parent_id` (optional, null = root level)
   - Returns list of folders with children nested
 2. `POST /api/v1/dms/folders` → 201, create folder
   - Body: `{name, parent_id?}`
   - Returns created folder with full path
 3. `PATCH /api/v1/dms/folders/{id}` → 200, rename/move folder
   - Body: `{name?, parent_id?}`
 4. `DELETE /api/v1/dms/folders/{id}` → 204, soft-delete (set deleted_at)
   - Cascade: soft-delete all child folders and files
 ### Files
 5. `POST /api/v1/dms/files/upload` → 201, multipart upload
   - Form fields: `file` (UploadFile), `folder_id?` (optional)
   - Store file on disk, create metadata record
   - Max file size: 100MB (configurable)
 6. `GET /api/v1/dms/files/{id}` → 200, file metadata
 7. `PATCH /api/v1/dms/files/{id}` → 200, rename/move
   - Body: `{name?, folder_id?}`
 8. `DELETE /api/v1/dms/files/{id}` → 204, soft-delete
 9. `POST /api/v1/dms/files/{id}/restore` → 200, restore from trash
 ### Preview & Edit
 10. `GET /api/v1/dms/files/{id}/preview` → 200, PDF stream
    - Only for PDF files (mime_type == application/pdf)
    - Return `StreamingResponse` with `media_type='application/pdf'`
    - Non-PDF files: return 400
 11. `POST /api/v1/dms/files/{id}/edit-session` → 200, OnlyOffice config
    - Return JSON config for OnlyOffice editor:
      ```json
      {
        "document": {"fileType": "docx", "key": "<uuid>", "title": "<filename>", "url": "<download_url>"},
        "editorConfig": {"mode": "edit", "callbackUrl": "<callback_url>", "user": {"id": "<user_id>", "name": "<user_name>"}}
      }
      ```
    - Only for Office files (docx, xlsx, pptx)
    - Non-Office files: return 400
 ### Sharing (INTERNAL — different from T11 permissions plugin)
 **NOTE**: T11 permissions plugin already handles:
 - `POST /api/v1/dms/files/{id}/share-link` — public share links with token
 - `GET /api/public/share/{token}` — public access
 - `POST /api/v1/dms/files/{id}/permissions` — grant permissions
 T04 DMS plugin handles INTERNAL sharing (different endpoints):
 12. `POST /api/v1/dms/files/{id}/share` → 200, internal share
    - Body: `{user_ids?: [uuid], group_ids?: [uuid], access_level: 'read'|'write'}`
    - Creates permission records (reuse permissions plugin Permission model OR DMS-specific)
 13. `DELETE /api/v1/dms/files/{id}/share` → 204, remove share
    - Body: `{user_id?: uuid, group_id?: uuid}`
 **IMPORTANT**: For `GET /api/public/share/{token}` (AC14, AC15) — T11 permissions plugin ALREADY implements this endpoint. Do NOT create a duplicate. If T11's endpoint already handles password-protected links (401 without password), then AC14 and AC15 are already satisfied. Verify by reading `app/plugins/builtins/permissions/routes.py`.
 ### Search & Bulk
 14. `GET /api/v1/dms/search?q=text` → 200, matching files
    - Case-insensitive filename search with ILIKE
    - Search across all files in tenant (not deleted)
 15. `GET /api/v1/dms/shared-with-me` → 200, shared files list
    - Files where user has been granted permission (via permissions plugin)
 16. `POST /api/v1/dms/files/bulk-move` → 200
    - Body: `{file_ids: [uuid], target_folder_id: uuid?}`
 17. `POST /api/v1/dms/files/bulk-delete` → 200
    - Body: `{file_ids: [uuid]}` — soft-delete all
 ## Migration SQL
 ```sql
 CREATE TABLE IF NOT EXISTS folders (
    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
    name VARCHAR(255) NOT NULL,
    parent_id UUID REFERENCES folders(id) ON DELETE CASCADE,
    tenant_id UUID NOT NULL,
    created_by UUID NOT NULL,
    deleted_at TIMESTAMP WITH TIME ZONE,
    created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
    updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
 );
 CREATE INDEX idx_folders_parent ON folders(parent_id) WHERE deleted_at IS NULL;
 CREATE INDEX idx_folders_tenant ON folders(tenant_id) WHERE deleted_at IS NULL;
 CREATE TABLE IF NOT EXISTS files (
    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
    name VARCHAR(255) NOT NULL,
    folder_id UUID REFERENCES folders(id) ON DELETE SET NULL,
    tenant_id UUID NOT NULL,
    uploaded_by UUID NOT NULL,
    mime_type VARCHAR(255) NOT NULL,
    size_bytes BIGINT NOT NULL,
    storage_path VARCHAR(1024) NOT NULL,
    deleted_at TIMESTAMP WITH TIME ZONE,
    created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
    updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
 );
 CREATE INDEX idx_files_folder ON files(folder_id) WHERE deleted_at IS NULL;
 CREATE INDEX idx_files_tenant ON files(tenant_id) WHERE deleted_at IS NULL;
 CREATE INDEX idx_files_name ON files USING gin (to_tsvector('simple', name));
 ```
 ## Register Plugin
 Add to `app/plugins/builtins/__init__.py`:
 ```python
 from app.plugins.builtins.dms import DmsPlugin
 __all__.append("DmsPlugin")
 ```
 ## Test File
 Create `tests/test_dms.py` with tests for ALL 19 ACs.
 ### Test Patterns
 - Follow existing test patterns in `tests/test_tags.py`, `tests/test_permissions.py`
 - Use async test client via `httpx.AsyncClient` with `ASGITransport`
 - Use existing fixtures from `tests/conftest.py`
 - For file upload tests: use `httpx.AsyncClient.post` with `files={'file': ('test.pdf', b'%PDF-1.4...', 'application/pdf')}`
 - For preview tests: verify response status 200 + content-type application/pdf
 - For OnlyOffice: verify config structure returned
 - For bulk operations: create multiple files, then bulk-move/bulk-delete
 ## Verification Commands
 ```bash
 cd /a0/usr/workdir/dev-projects/leocrm
 python -m pytest tests/test_dms.py -v --tb=short
 python -m pytest tests/test_dms.py --cov=app/plugins/builtins/dms --cov-report=term-missing
 ```
 ## Acceptance Criteria (19 — ALL must pass)
 1. GET /api/v1/dms/folders → 200 + folder tree
 2. POST /api/v1/dms/folders → 201, folder created with path
 3. PATCH /api/v1/dms/folders/{id} → 200, folder renamed/moved
 4. DELETE /api/v1/dms/folders/{id} → 204, soft-delete
 5. POST /api/v1/dms/files/upload (multipart) → 201, file stored + metadata
 6. GET /api/v1/dms/files/{id} → 200 + file metadata
 7. PATCH /api/v1/dms/files/{id} → 200, renamed/moved
 8. DELETE /api/v1/dms/files/{id} → 204, soft-delete
 9. POST /api/v1/dms/files/{id}/restore → 200, restored from trash
 10. GET /api/v1/dms/files/{id}/preview → 200 + PDF stream
 11. POST /api/v1/dms/files/{id}/edit-session → 200 + OnlyOffice config
 12. POST /api/v1/dms/files/{id}/share → 200, internal share created
 13. DELETE /api/v1/dms/files/{id}/share → 204, share removed
 14. GET /api/public/share/{token} → 200 (no auth, public access) — MAY already exist via T11
 15. GET /api/public/share/{token} mit password → 401 ohne password — MAY already exist via T11
 16. GET /api/v1/dms/search?q=text → 200 + matching files
 17. GET /api/v1/dms/shared-with-me → 200 + shared files list
 18. POST /api/v1/dms/files/bulk-move → 200, files moved
 19. POST /api/v1/dms/files/bulk-delete → 200, files soft-deleted
 ## Rules
 - No placeholder code. No Lorem Ipsum.
 - Follow existing patterns exactly (SQLAlchemy 2.0, FastAPI APIRouter, Pydantic v2)
 - All routes must have tenant_id scoping
 - Use `# noqa: F401` for __init__.py re-exports
 - Use `from None` in except blocks (B904)
 - File storage path: `/data/dms/{tenant_id}/{file_uuid}`
 - OnlyOffice: generate config only, don't run OnlyOffice server
 - For AC14/AC15: check if T11 permissions plugin already satisfies these. If yes, write tests that verify existing endpoint. If no, implement in DMS plugin.
 ## Deliverables
 - All plugin files created
 - Plugin registered in builtins __init__.py
 - tests/test_dms.py with all 19 ACs tested
 - All tests passing
 - Coverage ≥80%
 - Report: files created, test count + pass/fail, coverage %

 ## Recurrence Engine
 - Patterns: daily, weekly, monthly, yearly
 - Custom rules: e.g. 'every 2nd Tuesday' → store as JSONB {pattern: 'custom', custom_rule: 'BYDAY=TU;BYSETPOS=2'}
 - Exceptions: array of dates excluded from occurrence generation
 - Occurrence generation: given a date range query (start, end), generate all occurrence instances
 - Max 2 years forward for appointments
 - Tasks: generate next instance on completion (post-completion, not on-the-fly)
 ## ICS Export Format
 ```
 BEGIN:VCALENDAR
 VERSION:2.0
 PRODID:-//LeoCRM//Calendar//EN
 BEGIN:VEVENT
 UID:<entry_uuid>@leocrm
 DTSTART:<start_at>
 DTEND:<end_at>
 SUMMARY:<title>
 DESCRIPTION:<description>
 LOCATION:<location>
 END:VEVENT
 END:VCALENDAR
 ```
 - Token auth: each calendar has an `ics_token` (generate on first feed request, store in calendar_shares or a separate field)
 - Invalid token → 401
 ## ICS Import
 - Parse .ics file (VCALENDAR → VEVENT blocks)
 - Create CalendarEntry per VEVENT
 - Map: DTSTART→start_at, DTEND→end_at, SUMMARY→title, DESCRIPTION→description, LOCATION→location
 - Return: {entries_created: N, errors: [...]}
 - Use Python `icalendar` library if available, else parse manually
 ## Reminder System
 - reminder JSONB: {value: 15, unit: 'minutes', channel: 'in_app'}
 - When reminder is set on entry creation/update, schedule an ARQ job
 - ARQ job fires at (start_at - reminder) for appointments, (due_date - reminder) for tasks
 - Job sends in-app notification via EventBus
 - For now: just store the reminder config and schedule the ARQ job (don't need to implement the actual notification delivery)
 ## Calendar Sharing
 - Owner can share with user_id or group_id, permission read/write
 - User with read permission: can view entries, cannot edit (403 on PATCH/POST/DELETE)
 - User with write permission: can create/edit entries
 - Private subtype entries: only owner + admin can see (filter in query)

 ```
 ## Registration
 Add to `app/plugins/builtins/__init__.py`:
 ```python
 from app.plugins.builtins.calendar import CalendarPlugin
 __all__ = [..., "CalendarPlugin"]
 ```
 ## Test File: tests/test_calendar.py
 - Use shared fixtures from conftest.py (adapt: create calendar_app, calendar_client, calendar_authed_client)
 - OR add calendar fixtures to conftest.py (preferred — same pattern as DMS)
 - Test ALL 29 ACs
 - Coverage target: ≥80%
 - Add `concurrency = ["greenlet"]` already in pyproject.toml (done in T04)
 ## Test Patterns
 - httpx AsyncClient with ASGITransport
 - `ORIGIN_HEADER` from conftest
 - `authed_client` returns (client, seed) with admin_a, viewer_a, editor_a
 - Multipart upload for ICS import: `files={'file': ('test.ics', ics_content, 'text/calendar')}`
 - ICS feed: no auth header, just `?token=valid_or_invalid`
 - Recurrence test: create weekly entry, query range, verify occurrences
 - Resource conflict: create 2 bookings with overlapping time → 409
 ## Verification Commands
 ```bash
 cd /a0/usr/workdir/dev-projects/leocrm
 python -m pytest tests/test_calendar.py -v --tb=short
 python -m pytest tests/test_calendar.py --cov=app/plugins/builtins/calendar --cov-report=term-missing

 # 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

 # T07b Briefing — Frontend Feature Pages
 ## Project Root
 /a0/usr/workdir/dev-projects/leocrm
 ## Frontend Directory
 /a0/usr/workdir/dev-projects/leocrm/frontend/
 ## Task
 Build all feature pages for the LeoCRM SPA. T07a (shell, auth, routing, i18n, UI library) is complete.
 ## Tech Stack (already set up by T07a)
 - React 18 + Vite + TypeScript (strict)
 - TanStack Query v5 (hooks in src/api/hooks.ts)
 - Zustand (stores in src/store/)
 - react-i18next (de/en, src/i18n/)
 - React Hook Form + Zod
 - Tailwind CSS with design tokens
 - Vitest + @testing-library/react
 ## Existing API Hooks (src/api/hooks.ts)
 - useCompanies(page, pageSize, search) → { items, total, page, page_size }
 - useContacts(page, pageSize, search) → { items, total, page, page_size }
 - useUsers(page, pageSize) → paginated users
 - useCurrentUser() → current user
 - useNotifications() → notifications list
 - usePlugins() → plugins list
 - useLogin(), useLogout(), useSwitchTenant()
 - API client: src/api/client.ts (axios, withCredentials, 401→login, 422→validation)
 ## Backend API Endpoints
 - GET /api/v1/companies?page=1&page_size=25&search=...&industry=...&sort_by=...&sort_order=...
 - GET /api/v1/companies/{id} → CompanyDetailResponse (includes contacts[])
 - POST /api/v1/companies
 - PATCH /api/v1/companies/{id}
 - DELETE /api/v1/companies/{id}
 - GET /api/v1/companies/export?format=csv&search=...&industry=...
 - POST /api/v1/companies/import (CSV upload)
 - GET /api/v1/contacts?page=1&page_size=25&search=...
 - GET /api/v1/contacts/{id} → ContactDetailResponse (includes companies[])
 - POST /api/v1/contacts
 - PATCH /api/v1/contacts/{id}
 - DELETE /api/v1/contacts/{id}
 - GET /api/v1/users?page=1&page_size=25
 - GET /api/v1/users/{id}
 - POST /api/v1/users
 - PATCH /api/v1/users/{id}
 - DELETE /api/v1/users/{id}
 - GET /api/v1/notifications
 - GET /api/v1/plugins
 - GET /health
 Note: No dedicated audit log or global search API endpoint exists yet. For audit log, create a frontend page that calls GET /api/v1/audit (may 404 — handle gracefully with empty state). For global search, call useCompanies and useContacts with search param in parallel.
 ## Company Schema (from backend)
 - name: string (required, 1-100)
 - account_number: string? (max 40)
 - industry: string? (max 50)
 - phone: string? (max 30)
 - email: string? (max 255)
 - website: string? (max 500)
 - description: string?
 - CompanyDetailResponse adds: contacts: list[dict]
 ## Files to Create/Modify
 ### New API Hooks (add to src/api/hooks.ts)
 - useCompany(id), useCreateCompany(), useUpdateCompany(), useDeleteCompany()
 - useContact(id), useCreateContact(), useUpdateContact(), useDeleteContact()
 - useCompanyExport(), useCompanyImport()
 - useAuditLog(page, pageSize, filters)
 - useGlobalSearch(query, entityTypes)
 ### New Pages (src/pages/)
 - CompaniesList.tsx — TanStack Table with search/filter/sort/pagination, empty state
 - CompanyDetail.tsx — Tabs: overview, contacts, files, activity
 - CompanyForm.tsx — Create/edit with React Hook Form + Zod
 - ContactsList.tsx — TanStack Table, loading skeleton
 - ContactDetail.tsx — Tabs: overview, companies, files, activity
 - ContactForm.tsx — Create/edit with multi-company assignment
 - AuditLog.tsx — Filterable table (date, user, action, entity)
 - GlobalSearchResults.tsx — Filters (entity type, date), highlighting
 - SettingsProfile.tsx — Update name, email, password, avatar
 - SettingsRoles.tsx — Role editor: create, assign permissions
 - SettingsUsers.tsx — User management: list, invite, change role, deactivate
 ### Modify Existing Pages
 - Dashboard.tsx — Expand with stat cards + recent activity feed
 - Settings.tsx — Add tree navigation (Profile, Roles, Users, System)
 ### New Components (src/components/)
 - SearchDropdown.tsx — Global search dropdown in topbar
 - StatCard.tsx — Dashboard stat card
 - ActivityFeed.tsx — Recent activity feed
 - Tabs.tsx — Reusable tab component for detail pages
 - DataGrid.tsx — Wrapper around TanStack Table for list pages
 - CsvImportDialog.tsx — CSV upload → preview → import
 - UnsavedChangesGuard.tsx — Warn on navigation away with unsaved changes
 ### Update Routes (src/routes/index.tsx)
 Add routes for all new pages under ProtectedRoute children:
 - /companies, /companies/:id, /companies/new, /companies/:id/edit
 - /contacts, /contacts/:id, /contacts/new, /contacts/:id/edit
 - /audit-log
 - /search?q=...
 - /settings/profile, /settings/roles, /settings/users
 ### Tests (src/__tests__/)
 - companies/CompaniesList.test.tsx, CompanyDetail.test.tsx, CompanyForm.test.tsx
 - contacts/ContactsList.test.tsx, ContactDetail.test.tsx, ContactForm.test.tsx
 - settings/SettingsProfile.test.tsx, SettingsRoles.test.tsx, SettingsUsers.test.tsx
 - dashboard/Dashboard.test.tsx
 - search/GlobalSearch.test.tsx
 - AuditLog.test.tsx
 ## Acceptance Criteria (23 total)
 1. Companies list renders with TanStack Table (search, filter, sort, pagination)
 2. Company detail renders with tabs (overview, contacts, files, activity)
 3. Company form validates required fields (name) with Zod

 ## Test Commands
 ```bash
 cd /a0/usr/workdir/dev-projects/leocrm/frontend && npx vitest run src/__tests__/companies/ src/__tests__/contacts/ src/__tests__/settings/ src/__tests__/dashboard/ src/__tests__/search/ --reporter=verbose
 cd /a0/usr/workdir/dev-projects/leocrm/frontend && npm run build
 cd /a0/usr/workdir/dev-projects/leocrm/frontend && npx tsc --noEmit
 ```
 ## Rules
 - TypeScript only, no .js files
 - No Lorem Ipsum — use real German/English content
 - All interactive elements need ARIA labels
 - 44px minimum touch targets on mobile
 - Use existing UI components from T07a (Button, Input, Select, Modal, Toast, Table, Card, Badge, Avatar, Pagination, EmptyState, Skeleton, ConfirmDialog)
 - Use existing i18n setup — add new keys to de.json and en.json
 - Use existing API client (src/api/client.ts) — don't create new axios instances
 - Coverage target: 80%
 - Keep responses under 50 lines
 - Use files_create for new files, reference by path
 ## Deliverables
 1. All files created and tests passing
 2. npm run build succeeds with 0 errors
 3. tsc --noEmit passes with 0 errors
 4. Report: test results, AC coverage, files created, bugs encountered

 # T07b Continuation — Frontend Feature Pages (Part 2)
 ## Project Root
 /a0/usr/workdir/dev-projects/leocrm
 ## Frontend Directory
 /a0/usr/workdir/dev-projects/leocrm/frontend/
 ## What's Already Done (DO NOT recreate)
 ### API Hooks (src/api/hooks.ts — 432 lines, modified)
 16 new hooks already added: useCompany, useCreateCompany, useUpdateCompany, useDeleteCompany, useContact, useCreateContact, useUpdateContact, useDeleteContact, useCompanyExport, useCompanyImport, useAuditLog, useGlobalSearch, plus CRUD for users.
 ### Shared Components (src/components/shared/ — all exist)
 - `Tabs.tsx` (2055 bytes) — Tab navigation component
 - `StatCard.tsx` (1107 bytes) — Dashboard stat card
 - `ActivityFeed.tsx` (1372 bytes) — Activity feed list
 - `DataGrid.tsx` (6067 bytes) — TanStack Table wrapper with search/sort/pagination
 - `SearchDropdown.tsx` (6275 bytes) — Debounced search dropdown with highlighting
 - `CsvImportDialog.tsx` (5429 bytes) — CSV upload + preview dialog
 - `UnsavedChangesGuard.tsx` (821 bytes) — useBlocker-based unsaved changes warning
 ### Dependencies
 - @tanstack/react-table@8.21.3 installed
 ## What Remains (ALL of this must be created)
 ### 1. Feature Pages (src/pages/)
 **Companies:**
 - `CompaniesList.tsx` — Use DataGrid component, search/filter/sort/pagination, CSV import (CsvImportDialog) + export buttons, empty state with create button (AC 1, 4, 5, 20)
 - `CompanyDetail.tsx` — Tabs: overview, contacts, files, activity (AC 2)
 - `CompanyForm.tsx` — RHF + Zod, validate name required, unsaved changes guard (AC 3, 22)
 **Contacts:**
 - `ContactsList.tsx` — Use DataGrid, loading skeleton rows, empty state (AC 6, 21)
 - `ContactDetail.tsx` — Tabs: overview, companies, files, activity (AC 7)
 - `ContactForm.tsx` — RHF + Zod, validate first_name/last_name/email, multi-company assignment (AC 8, 9)
 **Settings:**
 - `SettingsProfile.tsx` — Update name, email, password, avatar (AC 11)
 - `SettingsRoles.tsx` — Create role, assign permissions, save (AC 12)
 - `SettingsUsers.tsx` — List users, invite user, change role, deactivate (AC 13)
 **Other:**
 - `AuditLog.tsx` — Filterable table (date, user, action, entity). Call useAuditLog hook. Handle 404 gracefully with empty state (AC 14)
 - `GlobalSearchResults.tsx` — Filters (entity type, date), highlight matched terms. Call useGlobalSearch hook (AC 17, 18)
 ### 2. Page Updates
 - `Dashboard.tsx` — Replace placeholder with stat cards (StatCard component) + recent activity feed (ActivityFeed component) (AC 15)
 - `Settings.tsx` — Add tree navigation (Profile, Roles, Users, System). Render child routes (AC 10)
 - `TopBar.tsx` — Add SearchDropdown in topbar for global search (AC 16)
 ### 3. Routes (src/routes/index.tsx)
 Add these routes:
 ```
 /companies              → CompaniesList
 /companies/:id          → CompanyDetail
 /companies/new          → CompanyForm
 /companies/:id/edit     → CompanyForm
 /contacts               → ContactsList
 /contacts/:id           → ContactDetail
 /contacts/new           → ContactForm
 /contacts/:id/edit      → ContactForm
 /audit-log              → AuditLog
 /search                 → GlobalSearchResults
 /settings/profile       → SettingsProfile
 /settings/roles         → SettingsRoles
 /settings/users         → SettingsUsers
 ```
 ### 4. i18n Updates (src/i18n/locales/de.json + en.json)
 Add translation keys for all new pages: companies, contacts, settings, audit_log, search, dashboard sections.
 ### 5. Tests (src/__tests__/)
 Create test files:
 - `companies/CompaniesList.test.tsx`
 - `companies/CompanyDetail.test.tsx`
 - `companies/CompanyForm.test.tsx`
 - `contacts/ContactsList.test.tsx`
 - `contacts/ContactDetail.test.tsx`
 - `contacts/ContactForm.test.tsx`
 - `settings/SettingsProfile.test.tsx`
 - `settings/SettingsRoles.test.tsx`
 - `settings/SettingsUsers.test.tsx`
 - `dashboard/Dashboard.test.tsx`
 - `search/GlobalSearch.test.tsx`
 - `AuditLog.test.tsx`
 ### 6. Verification
 Run these commands and report results:
 ```bash
 cd /a0/usr/workdir/dev-projects/leocrm/frontend
 npx vitest run src/__tests__/ --reporter=verbose
 npm run build
 npx tsc --noEmit
 ```
 ## Tech Stack
 - React 18 + Vite + TypeScript
 - TanStack Query v5 (hooks in src/api/hooks.ts)
 - Zustand (stores in src/store/)
 - react-i18next (de/en locales)
 - React Hook Form + Zod
 - Tailwind CSS
 - Vitest + @testing-library/react
 - @tanstack/react-table v8
 ## Existing UI Components (src/components/ui/)
 Avatar, Badge, Button, Card, ConfirmDialog, EmptyState, Input, Modal, Pagination, Select, Skeleton, Table, Toast
 ## Existing Layout (src/components/layout/)
 AppShell, Sidebar, TopBar
 ## API Client (src/api/client.ts)
 Axios instance with interceptors. Base URL: http://localhost:8000. Auth via session cookie.
 ## Backend API Endpoints
 ```
 GET/POST/PATCH/DELETE /api/v1/companies
 GET /api/v1/companies/{id}            # includes contacts[]
 GET /api/v1/companies/export?format=csv
 POST /api/v1/companies/import          # CSV upload
 GET/POST/PATCH/DELETE /api/v1/contacts
 GET /api/v1/contacts/{id}             # includes companies[]
 GET/POST/PATCH/DELETE /api/v1/users
 GET /api/v1/users/{id}
 GET /api/v1/notifications
 GET /api/v1/plugins
 GET /health
 ```
 Note: No /api/v1/audit endpoint exists yet. useAuditLog hook may 404 — handle gracefully.
 Note: No dedicated search endpoint. useGlobalSearch calls useCompanies + useContacts with search param.
 ## Company Schema
 ```python
 name: str (required, 1-100 chars)
 account_number: str | None (max 40)
 industry: str | None (max 50)
 phone: str | None (max 30)
 email: str | None (max 255)
 website: str | None (max 500)
 description: str | None
 ```
 ## Rules
 - TypeScript only, no .js files
 - No Lorem Ipsum — use real German/English content
 - Reuse existing UI components, don't recreate them
 - Keep responses under 50 lines — reference files by path
 - Use real content, not placeholder text
 - All 23 acceptance criteria must be covered
 - Test files must use @testing-library/react with vitest

 # 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)

 - `src/__tests__/tags/TagPicker.test.tsx` — tag picker tests
 - `src/__tests__/tags/BulkTagDialog.test.tsx` — bulk tag tests
 - `src/__tests__/permissions/ShareDialog.test.tsx` — share dialog tests
 ## Files to Modify
 - `src/routes/index.tsx` — Add /dms, /dms/trash routes
 - `src/components/layout/AppShell.tsx` — Add DMS + Tags menu items to sidebar

 ## Test Spec
 - Run: `cd /a0/usr/workdir/dev-projects/leocrm/frontend && npx vitest run src/__tests__/dms/ src/__tests__/tags/ src/__tests__/permissions/ --reporter=verbose`
 - Coverage: `npx vitest run src/__tests__/dms/ src/__tests__/tags/ --coverage`
 - Build: `npx vite build`
 - Type check: `npx tsc --noEmit`
 - Coverage target: 80%
 - Follow existing test pattern from src/__tests__/companies/ or src/__tests__/calendar/
 ## Forbidden Patterns
 - No inline styles — use Tailwind classes
 - No any types — use proper TypeScript interfaces
 - No direct fetch() — use apiClient from src/api/client.ts
 - No hardcoded strings — use i18n (t() function)
 - No Lorem Ipsum — use realistic test data
 - No missing loading/error/empty states
 ## Estimated Size
 - ~600 lines code (pages + components + API clients)
 - ~300+ lines tests

 - POST /labels — create label (with color)
 - GET /labels — list labels
 ## Frontend Architecture (follow existing patterns)
 - **Framework:** React + TypeScript + Vite
 - **Routing:** react-router-dom (src/routes/index.tsx)
 - **State:** TanStack Query (useQuery/useMutation)
 - **HTTP:** axios via src/api/client.ts (apiClient, baseURL /api/v1)
 - **API pattern:** See src/api/calendar.ts or src/api/dms.ts
 - **UI components:** src/components/ui/ (Button, Card, Input, Modal, Table, Badge, etc.)
 - **Shared:** src/components/shared/ (DataGrid, SearchDropdown, Tabs)
 - **Layout:** src/components/layout/AppShell.tsx + Sidebar.tsx
 - **i18n:** src/i18n/ (add de.json + en.json keys for Mail)
 - **Existing search page:** src/pages/GlobalSearchResults.tsx (enhance with tabs)
 ## Files to Create
 - `src/api/mail.ts` — Mail API client (types + functions for all endpoints)
 - `src/pages/Mail.tsx` — Mail page (folder tree + mail list + reading pane)
 - `src/pages/MailSettings.tsx` — Mail settings (signatures, rules, PGP, vacation, labels)
 - `src/components/mail/MailFolderTree.tsx` — folder tree sidebar
 - `src/components/mail/MailList.tsx` — mail list with pagination
 - `src/components/mail/MailDetail.tsx` — reading pane (sanitized HTML, attachments)
 - `src/components/mail/ComposeModal.tsx` — compose editor (bold/italic/link/template)
 - `src/components/mail/TemplatePicker.tsx` — template dropdown
 - `src/components/mail/SignatureManager.tsx` — signature CRUD
 - `src/components/mail/RuleEditor.tsx` — rule condition builder + action selector
 - `src/components/mail/LabelManager.tsx` — label CRUD with colors
 - `src/components/mail/VacationResponder.tsx` — vacation toggle + date range
 - `src/components/mail/PgpSettings.tsx` — PGP key import + contact keys
 - `src/components/mail/SharedMailboxSelector.tsx` — account switcher
 - `src/components/mail/MailSearchBar.tsx` — mail search input
 - `src/__tests__/mail/MailPage.test.tsx` — mail page tests
 - `src/__tests__/mail/ComposeModal.test.tsx` — compose tests
 - `src/__tests__/mail/MailSettings.test.tsx` — settings tests
 - `src/__tests__/search/GlobalSearchTabs.test.tsx` — search tabs tests
 ## Files to Modify
 - `src/routes/index.tsx` — Add /mail, /mail/settings routes
 - `src/components/layout/Sidebar.tsx` — Add Mail nav link
 - `src/pages/GlobalSearchResults.tsx` — Add tabs (companies/contacts/mails/files/events)
 - `src/components/layout/AppShell.tsx` — Add search autocomplete in TopBar
 - `src/i18n/locales/de.json` — Mail translations
 - `src/i18n/locales/en.json` — Mail translations
 ## Test Spec
 - Run: `cd /a0/usr/workdir/dev-projects/leocrm/frontend && npx vitest run src/__tests__/mail/ src/__tests__/search/ --reporter=verbose`
 - Build: `npx vite build`
 - Type check: `npx tsc --noEmit`
 - Coverage target: 80%
 - Follow existing test pattern from src/__tests__/dms/ or src/__tests__/companies/
 ## Forbidden Patterns
 - No inline styles — use Tailwind classes
 - No any types — use proper TypeScript interfaces
 - No direct fetch() — use apiClient from src/api/client.ts
 - No hardcoded strings — use i18n (t() function)
 - No Lorem Ipsum — use realistic test data
 - No missing loading/error/empty states
 - No dangerouslySetInnerHTML without sanitization check
 ## Estimated Size
 - ~700 lines code (pages + components + API client)
 - ~350+ lines tests

 ## Project Root
 /a0/usr/workdir/dev-projects/leocrm
 ## Backend Directory
 /a0/usr/workdir/dev-projects/leocrm/app/
 ## Tech Stack (existing)
 - FastAPI + SQLAlchemy 2.0 + asyncpg + Pydantic v2 + ARQ
 - PostgreSQL 18 on localhost:5432 (user/db: leocrm/leocrm + leocrm_test)
 - Redis on localhost:6379
 - venv at /opt/venv (already activated)
 - T01-T03 complete (103 tests pass, commit 7a5a48f)
 ## Requirements (5)
 F-AI-01, F-WF-01, F-CORE-01, F-CORE-06, F-TEST-01
 ## Acceptance Criteria (22)
 ### KI-Copilot (7 ACs)
 1. POST /api/v1/ai/copilot/query mit NL input → 200 + proposed_actions array
 2. POST /api/v1/ai/copilot/execute mit proposed action → 200 + API result (RBAC enforced)
 3. POST /api/v1/ai/copilot/execute als viewer mit delete action → 403 (RBAC blocks)
 4. GET /api/v1/ai/copilot/history → 200 + paginated conversation history
 5. Copilot action logged in audit_log with entity_type=ai_copilot
 6. Copilot respects tenant isolation: cross-tenant → 404
 7. Copilot respects field-level permissions: hidden fields not in response
 ### Workflow Engine (15 ACs)
 8. POST /api/v1/workflows mit valid steps JSONB → 201 + workflow definition
 9. GET /api/v1/workflows → 200 + paginated list
 10. GET /api/v1/workflows/{id} → 200 + workflow detail with steps
 11. PATCH /api/v1/workflows/{id} → 200, updated
 12. DELETE /api/v1/workflows/{id} → 204
 13. POST /api/v1/workflows/{id}/instances → 201, instance created with status=pending
 14. GET /api/v1/workflows/instances?status=in_progress → 200 + filtered list
 15. GET /api/v1/workflows/instances/{id} → 200 + current_step_index + history
 16. POST /api/v1/workflows/instances/{id}/advance (approve) → 200, step advanced
 17. POST /api/v1/workflows/instances/{id}/advance (reject) → 200, status=rejected, initiator notified
 18. POST /api/v1/workflows/instances/{id}/cancel → 200, status=cancelled
 19. Event-triggered workflow: publish event → workflow instance auto-starts
 20. workflow_step_history entry created on every step transition
 21. Code-engine workflow: onboarding workflow runs on user creation
 22. Approval step timeout → auto-reject after configured hours (tested with mock timer)
 ## Files to Create
 ### KI-Copilot
 - app/models/ai_conversation.py — AIConversation, AIMessage models (tenant-scoped)
 - app/schemas/ai_copilot.py — CopilotQueryRequest, CopilotAction, CopilotExecuteRequest, CopilotHistoryResponse
 - app/services/ai_copilot_service.py — NL→API translation, LLM client, RBAC enforcement, audit logging
 - app/routes/ai_copilot.py — POST /query, POST /execute, GET /history
 - app/ai/__init__.py
 - app/ai/llm_client.py — Configurable LLM client (AI_MODEL, AI_API_KEY env vars)
 - app/ai/action_mapper.py — Maps NL intents to API calls
 ### Workflow Engine
 - app/models/workflow.py — Workflow, WorkflowInstance, WorkflowStepHistory models (tenant-scoped)
 - app/schemas/workflow.py — WorkflowCreate, WorkflowResponse, InstanceCreate, InstanceResponse, AdvanceRequest
 - app/services/workflow_service.py — CRUD workflows, instance lifecycle (start/advance/approve/reject/cancel)
 - app/routes/workflows.py — Workflow CRUD + instance endpoints
 - app/workflows/__init__.py
 - app/workflows/code/__init__.py — Code-engine workflows
 - app/workflows/code/onboarding.py — Onboarding workflow (runs on user creation)
 - app/workflows/engine.py — Workflow execution engine (step processing, conditions, approvals)
 ### Tests
 - tests/test_ai_copilot.py — 7 AC tests + edge cases
 - tests/test_workflows.py — 15 AC tests + edge cases
 ### Migration
 - alembic/versions/0004_ai_workflows.py — ai_conversations, ai_messages, workflows, workflow_instances, workflow_step_history tables (all tenant-scoped with RLS)
 ## Files to Modify
 - app/main.py — Register ai_copilot + workflows routers
 - app/models/__init__.py — Add new model imports
 - app/routes/__init__.py — Add new router imports
 - app/schemas/__init__.py — Add new schema imports
 - app/services/__init__.py — Add new service imports
 - tests/conftest.py — Add new tables to TRUNCATE list
 - app/core/event_bus.py — Add workflow event trigger integration (if not already present)
 ## LLM Client Design
 - Read AI_MODEL and AI_API_KEY from environment
 - If not set, use mock/stub mode (returns predefined actions for tests)
 - Support OpenAI-compatible API (default)
 - NL → proposed API calls: method, path, body, description
 - Never execute directly — always return proposed actions for user confirmation
 ## Workflow Engine Design
 - Step types: action, approval, notification, condition
 - Workflow definition: JSONB steps array
 - Instance lifecycle: pending → in_progress → completed/rejected/cancelled
 - Event bus integration: subscribe to events, auto-start workflows with matching trigger
 - Code-engine: hardcoded workflows in app/workflows/code/ (onboarding on user.created event)
 - Approval timeout: configurable hours, auto-reject via ARQ scheduled job or mock timer in tests
 ## Critical Rules
 - All POST routes MUST have status_code=201 (except execute/advance/cancel which are actions → 200)
 - Use set_config() for tenant context, NOT SET LOCAL
 - Use .com emails in tests, NOT .test
 - All new tables MUST have tenant_id column + RLS policies
 - Update tests/conftest.py TRUNCATE list with new tables
 - Create Alembic migration 0004 for all new tables
 - Copilot MUST enforce RBAC (same middleware, same permissions)
 - Copilot MUST respect tenant isolation and field-level permissions
 - Audit log entity_type=ai_copilot for all copilot actions
 - Workflow mutations MUST be logged in workflow_step_history
 - Idempotent where applicable

 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)

 # T11 Briefing — Tags Plugin + Permissions Plugin + Entity Links Backend
 ## Project Root
 /a0/usr/workdir/dev-projects/leocrm
 ## Task
 Implement 3 builtin plugins: Tags, Permissions, Entity Links.
 ## Plugin Framework (existing — read these files first)
 - `app/plugins/base.py` — BasePlugin abstract class with lifecycle hooks
 - `app/plugins/manifest.py` — PluginManifest, PluginRouteDef schemas
 - `app/plugins/registry.py` — PluginRegistry (discovers builtins, manages lifecycle)
 - `app/plugins/builtins/test_sample.py` — Example plugin (reference pattern)
 - `app/plugins/builtins/migrations/` — Migration SQL files go here
 - `app/core/event_bus.py` — EventBus for pub/sub
 - `app/core/service_container.py` — DI container
 - `app/core/db.py` — Base, TenantMixin, TimestampMixin
 - `app/models/company.py` — Company model (reference for model patterns)
 - `app/models/plugin.py` — Plugin + PluginMigration models
 ## Architecture Rules
 - Plugins live in `app/plugins/builtins/` as subdirectories (e.g. `app/plugins/builtins/tags/`)
 - Each plugin has: `__init__.py` (exports plugin class), `plugin.py` (BasePlugin subclass), `routes.py` (APIRouter), `models.py` (SQLAlchemy models), `schemas.py` (Pydantic schemas), `migrations/` (SQL files)
 - Migrations are plain SQL files in `app/plugins/builtins/<plugin>/migrations/`
 - Models use SQLAlchemy 2.0 style (Mapped, mapped_column) with PGUUID, TenantMixin
 - Routes use FastAPI APIRouter, registered via manifest routes list
 - Events: subscribe in on_activate, handlers named `on_<event_name>`
 ## 1. Tags Plugin (`app/plugins/builtins/tags/`)
 ### Requirements (F-TAG-01 through F-TAG-04)
 - Tags can be applied to files, folders, companies, contacts
 - Tags are global (not per-user), centrally managed
 - Multiple tags per entity (N:M)
 - Tag CRUD with color support
 - Tag filtering in lists (AND/OR combination)
 - Tag cloud/sidebar with entity counts
 ### Endpoints
 ```
 GET    /api/v1/tags              → 200, list tags with entity counts
 POST   /api/v1/tags              → 201, create tag (name, color)
 PATCH  /api/v1/tags/{id}          → 200, update tag
 DELETE /api/v1/tags/{id}          → 204, cascade delete assignments
 POST   /api/v1/tags/assign        → 200, assign tag to entity (tag_id, entity_type, entity_id)
 DELETE /api/v1/tags/assign        → 204, remove tag assignment
 POST   /api/v1/tags/bulk-assign   → 200, assign multiple tags to entity
 GET    /api/v1/tags/{id}/entities → 200, list entities with this tag
 ```
 ### Models
 - `Tag`: id (UUID), name (str, unique per tenant), color (str, hex), tenant_id
 - `TagAssignment`: id, tag_id (FK), entity_type (str: company/contact/file/folder), entity_id (UUID), tenant_id
 ### Migration
 - `0001_initial.sql`: Create `tags` and `tag_assignments` tables with tenant_id columns
 ## 2. Permissions Plugin (`app/plugins/builtins/permissions/`)
 ### Requirements (F-PERM-01 through F-PERM-06)
 - Personal root folder per user ("Mein Bereich")
 - Shared root folders for teams/departments
 - Share files/folders with individual users (read/write)
 - Share files/folders with user groups (read/write)
 - Public share links (with password, expiry, download-only or preview+download)
 - Permission display (who has access?)
 ### Endpoints
 ```
 GET    /api/v1/dms/files/{id}/permissions          → 200, permission list
 POST   /api/v1/dms/files/{id}/permissions          → 201, grant permission
 DELETE /api/v1/dms/files/{id}/permissions/{user_id} → 204, revoke
 POST   /api/v1/dms/files/{id}/share-link           → 200, create share link (returns public token URL)
 GET    /api/public/share/{token}                   → 200 (file) or 410 (expired)
 DELETE /api/v1/dms/share-links/{id}                → 204, revoke share link
 ```
 ### Models
 - `Permission`: id, file_id (UUID), user_id (UUID), group_id (UUID nullable), access_level (read/write), tenant_id
 - `ShareLink`: id, file_id (UUID), token (str, unique), password_hash (nullable), expires_at (nullable), access_level (download/preview), tenant_id
 ### Migration
 - `0001_initial.sql`: Create `permissions` and `share_links` tables
 ### Special
 - Public share endpoint `/api/public/share/{token}` must NOT require auth
 - Expired links return 410 Gone
 - Password-protected links verify password before serving
 ## 3. Entity Links Backend (`app/plugins/builtins/entity_links/`)
 ### Requirements (F-LINK-01 through F-LINK-06)
 - Link files/folders to companies (N:M)
 - Link files/folders to contacts (N:M)
 - Reverse links (file shows linked entities)
 - Multi-links (one file → many entities)
 - Event cleanup: on company.deleted/contact.deleted → remove links
 ### Endpoints
 ```
 POST   /api/v1/dms/files/{id}/link    → 200, link file to entity (entity_type, entity_id)
 DELETE /api/v1/dms/files/{id}/link    → 204, remove link (entity_type, entity_id in body)
 GET    /api/v1/dms/files/{id}/links    → 200, list all linked entities for file
 GET    /api/v1/companies/{id}/files   → 200, list linked files for company
 GET    /api/v1/contacts/{id}/files    → 200, list linked files for contact
 ```
 ### Models
 - `EntityLink`: id, file_id (UUID), entity_type (str: company/contact), entity_id (UUID), tenant_id, created_by (UUID)
 ### Migration
 - `0001_initial.sql`: Create `entity_links` table
 ### Event Handling
 - Subscribe to `company.deleted` → delete all EntityLink rows where entity_type='company' AND entity_id=deleted_id
 - Subscribe to `contact.deleted` → delete all EntityLink rows where entity_type='contact' AND entity_id=deleted_id
 ## Acceptance Criteria (14 total — ALL must pass)
 1. GET /api/v1/dms/files/{id}/permissions → 200 + permission list
 2. POST /api/v1/dms/files/{id}/link → 200, file linked to entity
 3. DELETE /api/v1/dms/files/{id}/link → 204, link removed
 4. POST /api/v1/dms/files/{id}/share-link → 200 + public token URL
 5. GET /api/public/share/{token} with expired link → 410
 6. GET /api/v1/tags → 200 + tags with counts
 7. POST /api/v1/tags → 201, tag created
 8. PATCH /api/v1/tags/{id} → 200
 9. DELETE /api/v1/tags/{id} → 204, cascade delete assignments
 10. POST /api/v1/tags/assign → 200, tag assigned to entity
 11. DELETE /api/v1/tags/assign → 204, tag removed
 12. POST /api/v1/tags/bulk-assign → 200, multiple tags assigned
 13. DMS plugin listens to company.deleted event → linked files cleanup
 14. Folder permissions enforced: user without read → 403
 ## Test Files (create in `tests/`)
 - `tests/test_tags.py` — Tag CRUD, assignment, bulk assign, cascade delete, counts
 - `tests/test_permissions.py` — Personal root, shared root, share with users/groups, share links (password, expiry), permission display, 403 enforcement
 - `tests/test_entity_links.py` — Link file to company, link to contact, reverse links, multi-links, event cleanup on deletion

 # 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

 # LeoCRM — AGENTS.md
-**Projekt:** leocrm
+**Projekt:** leocrm | **Stack:** FastAPI + SQLAlchemy + PostgreSQL 16 (pgvector) + React/TypeScript/Vite/Tailwind
-**Erstellt:** 2026-06-28
+
-**Status:** Draft — ready for implementation
+---
 ## 0. BINDENDE REGEL: Auf bestehendem Code aufbauen (NICHT VERHANDELBAR)
 ### 0.0 Sub-Agents / Subordinates — Nuancierte Regel
 **Sub-Agents (call_subordinate) nur für einfache Jobs verwenden.**
 - Einfache Jobs: Research, Codebase-Exploration, Dokumentations-Zusammenfassung — Aufgaben ohne Code-Änderungen oder Schema-Migrationen.
 - Komplexe Jobs (Code-Änderungen, Tests, Migrationen, Deployments): vom Haupt-Agent selbst ausführen.
 - Wenn der User sagt "keine Sub-Agents verwenden": daran halten, keine Ausnahmen.
 - Sub-Agents haben in der Vergangenheit Code geschrieben der nicht gegen Produktion verifiziert wurde, Schema-Drifts verursacht und nicht getestet hat. Qualitätssicherung bleibt beim Haupt-Agent.
 **Gültig für jegliche Arbeit an diesem Projekt.**
 ### 0.1 Pflicht zur Analyse vor Implementierung
 Der Agent MUSS vor jeder Implementierung das bestehende System analysieren:
 1. **Backend lesen:** Welche Models, Routes, Services, Plugins, Contracts, Hooks, ARQ-Jobs existieren bereits für den betroffenen Bereich? Der Agent greppt und liest die relevanten Dateien BEVOR er Code schreibt.
 2. **Frontend lesen:** Welche Pages, Components, Stores, Hooks, API-Clients, Block-Typen, Sidebar-Tabs existieren bereits für den betroffenen Bereich? Der Agent greppt und liest die relevanten Dateien BEVOR er Code schreibt.
 3. **Datenbank lesen:** Welche Tabellen, Foreign Keys, RLS-Policies, Migrationen existieren bereits? Der Agent prüft `alembic/versions/` und die Produktions-DB BEVOR er neue Migrationen schreibt.
 4. **Plugin-System lesen:** Welche Contracts, Manifests, Search Provider, Tools, Hooks existieren bereits in den betroffenen Plugins? Der Agent liest `plugin.py`, `contracts.py`, `manifest.py` BEVOR er neue Plugins oder Erweiterungen baut.
 ### 0.2 Pflicht zum Aufbau auf bestehendem Code
 Der Agent MUSS auf bestehendem Code aufbauen. Es ist VERBOTEN:
 - ❌ Parallele Systeme zu bauen die vorhandene Funktionalität duplizieren (z.B. ein separates Workstream-System wenn das `kommunikation` Plugin schon Conversations, Messages, Blocks, WebSocket hat)
 - ❌ Neue Frontend-Pages zu bauen wenn vorhandene Pages die Funktion aufnehmen können (z.B. Dashboard, Communication, AgentDashboard, Workflows, Wiki, Settings)
 - ❌ Neue Sidebars oder Panels zu bauen wenn die AISidebar (5 Tabs) oder MessageSidebar die Funktion aufnehmen können
 - ❌ Neue Stores zu bauen wenn vorhandene Stores (commStore, uiStore, authStore, etc.) die Funktion aufnehmen können
 - ❌ Neue API-Clients zu bauen wenn vorhandene API-Clients (api/comm.ts, api/ai.ts, api/automation.ts, etc.) die Funktion abdecken können
 - ❌ Neue Block-Typen zu bauen wenn vorhandene Block-Typen (action_card, contact_card, miniapp, etc.) die Funktion abdecken können
 - ❌ Dataclasses zu schreiben wenn echte SQLAlchemy Models + FastAPI Routes die richtige Lösung sind
 - ❌ Mock-Tests zu schreiben wenn echte Integration-Tests mit der Test-DB möglich sind
 - ❌ Module zu bauen die 0 Referenzen aus Routes/Plugins haben (unverbundener Code)
 - ❌ Tasks als "done" zu markieren ohne echte Verifizierung (curl gegen echte API, grep-Beweis für Import-Verbindungen, tsc clean, Backend import OK)
 ### 0.3 Pflicht zur Verbindung
 Jeder neue Code MUSS mit dem bestehenden System verbunden werden:
 - **Backend:** Neue Module müssen in `app/main.py` oder in Plugin `routes.py` registriert werden. Neue Models müssen in `alembic/versions/` migriert werden. Neue Tools müssen im `tool_registry` registriert werden. Neue Hooks müssen in `plugin.py on_activate` registriert werden. Neue ARQ-Jobs müssen in `worker.py` registriert werden.
 - **Frontend:** Neue Components müssen in vorhandene Pages integriert werden (nicht als neue Page). Neue API-Calls müssen vorhandene API-Clients nutzen oder erweitern. Neue Block-Typen müssen im `BlockRenderer.tsx` registriert werden. Neue Sidebar-Tabs müssen in der `AISidebar.tsx` registriert werden.
 - **Verifizierung:** Der Agent beweist mit grep dass neue Module importiert/referenziert werden. Der Agent beweist mit curl/pytest dass die API funktioniert. Der Agent markiert nichts als "done" ohne diese Beweise.
 ### 0.4 Referenz-Architektur (was existiert und genutzt werden MUSS)
 **Frontend-Struktur:**
 - `AISidebar.tsx` — 5 Tabs: chat (KI Chat), proactive (Live KI/Suggestions), notifications, team, chatroom (Communication)
 - `MessageSidebar.tsx` (671 Zeilen) — voller Chat mit Conversations, Messages, WebSocket, BlockRenderer
 - `Communication.tsx` (859 Zeilen) — volle Chat-Seite mit Conversations (system/ai/colleague), Messages, Blocks, Pin/Unpin, Read
 - `comm/blocks/` — 10 Block-Typen: text, markdown, html, image, audio, video, file, action_card, contact_card, miniapp
 - `BlockRenderer.tsx` — rendert alle Block-Typen
 - `Dashboard.tsx` — StatCards, ActivityFeed, DashboardGrid mit Widgets
 - `AgentDashboard.tsx` — Agent CRUD, Execute, Test Run, Versions, Restore, Tools, Send Message
 - `Workflows.tsx` — Workflow CRUD, Instances, Editor, Step Config
 - `Wiki.tsx` — Categories, Articles, Markdown Editor, Version History, Restore
 - `components/knowledge/` — AskKnowledge.tsx, KnowledgeGraph.tsx
 - `components/onboarding/` — OnboardingTour.tsx, WelcomeDialog.tsx
 - `components/agents/` — AgentChat, AgentEditor, AgentMonitor, AgentRunLog
 - `components/workflows/` — StepConfigPanel, WorkflowEditor, WorkflowInstanceList, WorkflowInstanceDetail
 - `components/dashboard/` — DashboardGrid, RecentContactsWidget, TasksSummaryWidget, CalendarUpcomingWidget
 - `store/commStore.ts` — Conversation, Message, MessageBlock, MessageAttachment, Participant
 - `store/uiStore.ts` — aiSidebarCollapsed, aiSidebarTab, notifications
 - `api/comm.ts` — listConversations, getMessages, sendMessage, markRead, createConversation
 - `api/ai.ts` — createSession, fetchSessions, streamChat, fetchAgents
 - `api/automation.ts` — useAgents, useCreateAgent, useUpdateAgent, useDeleteAgent, useExecuteAgent, useTestRunAgent, useAgentRuns, useAgentVersions, useRestoreAgentVersion, useAgentTools, useSendAgentMessage
 - `api/workflows.ts` — useWorkflows, useDeleteWorkflow, useUpdateWorkflow
 - `api/knowledge.ts` — createWikiArticle, deleteWikiArticle, fetchWikiArticle, fetchWikiCategories, fetchWikiVersions, restoreWikiVersion, updateWikiArticle
 **Backend-Struktur:**
 - `kommunikation` Plugin — CommConversation, CommParticipant, CommMessage, CommMessageBlock, WebSocket, Contracts, MiniAppRegistry
 - `automation` Plugin — AgentDefinition, AgentRun, AgentRunStep, Triggers, Schedules, Pre-built Agents
 - `unified_search` Plugin — 14 Search Provider, Hybrid Search, Embeddings
 - `graph_rag` Plugin — Knowledge Graph, Relationships, Entities
 - `wiki` Plugin — WikiArticle, WikiCategory, WikiArticleVersion, Entity Links

 - `app/ai/` — agent_loop.py, agent_runner.py, llm_client.py, context_builder.py, agent_permissions.py, agent_tools.py, data_policy.py, transparency.py, oversight.py, agent_stream.py, skill_registry.py, ai_use_case.py
 - `app/workflows/` — engine.py, step_handlers.py, decision_guard.py
 - `app/core/` — approval.py, hooks.py, outbox.py, worker.py, storage.py, monitoring.py, notifications.py
 - `app/routes/` — 468 API Routes über alle Plugins und Core-Module
 **Datenbank:**
 - 130 Tabellen, 159 Foreign Keys, 590 Indexes
 - 114 Tabellen mit RLS (Row Level Security)
 - 130 Alembic Migrationen (Head: 0130)
 - `set_tenant_context()` setzt `app.current_tenant_id` für RLS
 ### 0.5 Konsequenzen bei Verstoss
 Wenn der Agent gegen diese Regel verstösst:
 1. Der Code wird nicht akzeptiert
 2. Der Agent muss den Code löschen und auf bestehendem Code neu aufbauen
 3. Der Agent muss den Verstoß dokumentieren und erklären warum er die Regel ignoriert hat
 4. Der Agent muss PROVE dass der neue Code mit grep-imports verbunden ist BEVOR er als done markiert wird

 ## 2. Test Rules
-### TDD (Test-Driven Development)
+- TDD: failing test first → implement → refactor
-
+- NEVER modify tests to make them pass — fix the code
- **Red-Green-Refactor:** Write failing test first → implement minimum code to pass → refactor.
+- Test DB: ephemeral PostgreSQL, NEVER production DB
- **Every new endpoint gets a test BEFORE implementation.**
+- Mock external services (SMTP, IMAP, OnlyOffice) with AsyncMock
- **Every bug fix starts with a reproduction test.**
+- Tests must be deterministic and isolated
 ### Coverage Targets
 | Layer | Coverage Target | Measured By |
 |-------|----------------|-------------|
 | Backend Core (app/core/) | 85% | pytest-cov |
 | Backend Models+Services | 85% | pytest-cov |
 | Backend Routes | 85% | pytest-cov |
 | Backend Plugins | 80% | pytest-cov |
 | Frontend Components | 75% | vitest coverage |
 | Frontend Plugin UI | 70% | vitest coverage |
 | E2E (critical paths) | 100% of defined specs | Playwright |

 ### Test Conventions
 - **Test names:** `test_<action>_<condition>_<expected_result>` (e.g., `test_login_with_invalid_credentials_returns_401`)
 - **Test structure:** Arrange → Act → Assert (AAA pattern)
 - **Fixtures:** Use `conftest.py` for shared fixtures. No fixture duplication across files.
 - **Test DB:** Use in-memory or ephemeral PostgreSQL (via testcontainers or pytest-postgresql). NEVER test against production DB.
 - **Mocking:** Mock external services (SMTP, IMAP, OnlyOffice) in tests. Use `unittest.mock.AsyncMock` for async mocks.
 - **Assertions:** Use pytest's native `assert` for backend, `expect()` from `@testing-library/jest-dom` for frontend.
 - **No flaky tests:** Tests must be deterministic. Use explicit waits, not sleeps.
 - **Test isolation:** Each test must be independent. No test depends on another test's side effects.
 ### Don't Modify Tests Rule
 - **NEVER modify existing tests to make them pass.** If a test fails, fix the code, not the test.
 - **Exception:** If the test itself is wrong (testing incorrect behavior), document why and get approval before changing.
 - **Test files are owned by the QA process, not the implementer.**

-### Backend Naming Conventions
+### Git
-
+- Conventional Commits: `feat(core): ...`, `fix(dms): ...`
- **Files:** `snake_case.py` (e.g., `company_service.py`)
+- Squash merge to main after review
 - **Classes:** `PascalCase` (e.g., `CompanyService`, `CompanyModel`)
 - **Functions/Methods:** `snake_case` (e.g., `get_company_by_id`)
 - **Constants:** `UPPER_SNAKE_CASE` (e.g., `SESSION_TIMEOUT_HOURS`)
 - **Models:** `<Entity>Model` suffix or just `<Entity>` (e.g., `Company`, `Contact`)
 - **Schemas:** `<Entity>Create`, `<Entity>Update`, `<Entity>Read`, `<Entity>List` (Pydantic)
 - **Services:** `<Entity>Service` (e.g., `CompanyService`)
 - **Routers:** `<entity>_router` variable, file name `<entity>_router.py`
 - **Tests:** `test_<domain>.py` (e.g., `test_companies.py`)
 ### Backend Code Conventions
 - **Async first:** All route handlers and service methods are `async def`.
 - **Type hints:** All function signatures have type hints (Python 3.12+ syntax).
 - **Docstrings:** All public functions/classes have docstrings (Google style).
 - **Error handling:** Use FastAPI `HTTPException` with proper status codes. Never raise generic `Exception`.
 - **Validation:** Pydantic schemas validate input. Never validate in routes directly.
 - **Tenant scoping:** Never query without tenant filter (ORM auto-filter handles this, but be aware).
 - **UUID:** All IDs are UUID. Never use integer auto-increment.
 - **Timestamps:** All datetime fields are `TIMESTAMPTZ`. Never use naive datetime.
 - **Soft-delete:** Use `deleted_at IS NULL` filter. Never hard-delete without explicit `gdpr=true` flag.
 - **Audit:** All mutations must create audit log entries. Use the audit middleware/decorator.

+- ❌ Secrets in docker-compose.yml
 | 5 | T10 | No | implementation_engineer | Monitoring, Performance, Doku, Environment Config |
 #### v2 Plugin Phases (nach v1 Deployment)

 ### Parallelization Notes
 **v1 Phases:**
 - **Phase 2:** T02 (Company/Contact) and T03 (Plugin Framework) are independent after T01 — safe to run in parallel.
 - **Phase 3:** T07a (Frontend Shell+Auth+UI Library) depends only on T01. T09 (KI/Workflow) depends on T01+T02. Both can run in parallel if API contracts are frozen.
 - **Phase 4:** T07b (Frontend Feature Pages) depends on T07a (UI library, routing, auth) + T02 (company/contact API). Must run after T07a.
 - **Phase 5:** T10 (Monitoring+Doku) depends on T01+T02. Can run parallel with T07b.
 **v2 Phases (after v1 deployment):**
 - **Phase 6:** T04 (DMS), T05 (Calendar), T06 (Mail), T11 (Tags+Perm) all depend on T01+T03 — safe to run in parallel.
 - **Phase 7:** T08a/T08b/T08c depend on T07b + respective backend (T04/T05/T06) — safe to run in parallel.
 ### Block Rules
 - Block = max 3 Tasks per implementation block.
 - After each block: quality_reviewer review → block_compactor → context_compactor → User checkpoint.
 - quality_reviewer and release_auditor do NOT count toward the 3-task limit.
 - After 3 blocks (9 tasks): release_auditor runs full audit.
 - Token budget: ~3000 tokens per task. If tool result >5000 tokens: context_compactor.

-## 5. Forbidden Patterns
+## 5. Quality Gates
-### Backend Forbidden
+- Per-Task: tests pass, coverage met, tsc/ruff clean, build succeeds, no forbidden patterns
-
+- Phase: all tasks pass → quality_reviewer review → user checkpoint
- ❌ **SQLite:** No SQLite as database. PostgreSQL 16 only (ADR-01).
+- Release: all tasks complete → release_auditor audit → Docker builds → health 200 → E2E pass
 - ❌ **Jinja2:** No server-side HTML rendering. API-only backend (ADR-03).
 - ❌ **Cross-Tenant Data Access:** No query without tenant_id filter. ORM auto-filter must not be bypassed.
 - ❌ **Plaintext Passwords:** Passwords must be bcrypt-hashed (cost=12). Never store or log plaintext.
 - ❌ **JWT Tokens:** No JWT auth in v1. Session-based auth with HttpOnly cookies only (ADR-05).
 - ❌ **Naive Datetime:** All datetime fields must be timezone-aware (TIMESTAMPTZ). Never use `datetime.now()` without tz.
 - ❌ **Integer IDs:** All primary keys are UUID. Never use auto-increment integer IDs.
 - ❌ **Hard-Delete without GDPR flag:** Companies/Contacts use soft-delete. Hard-delete only with explicit `?gdpr=true`.
 - ❌ **Manual Tenant Filter:** Never manually add `.filter(Tenant.id == x)` in services. The ORM auto-filter handles this.
 - ❌ **Sync I/O in Routes:** All route handlers are `async def`. Never use blocking I/O (use `asyncpg`, `aiofiles`, etc.).
 - ❌ **Raw SQL without Tenant Check:** Any raw SQL query must explicitly include `tenant_id` filter.
 - ❌ **Secrets in Code:** No hardcoded secrets. All secrets via environment variables.
 - ❌ **Unvalidated Input:** All request bodies validated by Pydantic schemas. Never trust raw request data.
 - ❌ **Missing Audit Log:** All create/update/delete operations must create audit log entries.
 - ❌ **Plugin Tables without tenant_id:** All plugin-created tables must include `tenant_id` column. The migration validator enforces this.
 ### Frontend Forbidden
 - ❌ **Class Components:** No class components. Functional components with hooks only.
 - ❌ **Inline Styles:** No `style={{}}` props. Use Tailwind utility classes.
 - ❌ **Hardcoded Strings:** No user-visible hardcoded strings. Use `t()` from i18n.
 - ❌ **Manual Fetch in Components:** No `fetch()` or `axios` calls in components. Use TanStack Query hooks.
 - ❌ **Server Data in Zustand:** Zustand is for client state only. Server data goes in TanStack Query.
 - ❌ **`any` Types:** No `any` type. Use proper TypeScript types.
 - ❌ **Missing ARIA Attributes:** All interactive elements must have ARIA labels.
 - ❌ **Touch Targets < 44px:** All buttons/links must have minimum 44px touch target.
 - ❌ **Direct DOM Manipulation:** No `document.getElementById()` or `querySelector()` in components. Use React refs.
 - ❌ **Unsafe HTML Rendering:** No `dangerouslySetInnerHTML` without sanitization. Mail bodies must be sanitized (DOMPurify equivalent).
 ### Deployment Forbidden
 - ❌ **Running as Root in Container:** Containers run as non-root user (app:app).
 - ❌ **Exposed DB Port in Production:** PostgreSQL port (5432) must not be exposed externally in production.
 - ❌ **No Health Check:** All services must have Docker health checks configured.
 - ❌ **No Volume for Storage:** File storage must use a named volume, not ephemeral container storage.
 - ❌ **Secrets in docker-compose.yml:** No secrets in compose file. Use `.env` file or Docker secrets.

-## 6. Quality Gates
+## 6. ADRs
 ### Per-Task Quality Gate
 Before a task is marked complete:
 1. All test_spec commands must pass.
 2. Coverage target must be met (measured by pytest-cov / vitest coverage).
 3. TypeScript compiles without errors (`tsc --noEmit`).
 4. Linting passes (ruff for backend, eslint for frontend).
 5. Build succeeds (Vite build for frontend, no build step for backend).
 6. No forbidden patterns detected.
 7. All acceptance criteria verified as testable.
 ### Phase Gate (after each phase)
 1. All tasks in the phase pass their quality gates.
 2. quality_reviewer subagent reviews the phase output.
 3. No critical issues from quality_reviewer.
 4. Block compactor saves progress.
 5. User checkpoint before next phase.
 ### Release Gate (before v1 deployment)
 1. All 7 v1 tasks complete (T01, T02, T03, T07a, T07b, T09, T10).
 2. release_auditor runs full audit.
 3. Docker Compose builds and starts successfully.
 4. Health endpoint returns 200.
 5. E2E tests (Playwright) pass.
 6. All forbidden patterns checked.
 ### v2 Release Gate (before v2 plugin deployment)
 1. All 7 v2 tasks complete (T04, T05, T06, T11, T08a, T08b, T08c).
 2. release_auditor runs full audit.
 3. All plugin backends + frontends pass quality gates.
 4. Plugin install/activate/deactivate lifecycle tested.
 5. All forbidden patterns checked.

 ---
 ## 9. Progress-Tracking & Forgejo-Issue-Verwaltung
 ### Planungs- und Fortschrittsdateien
 | Datei | Zweck | Wann aktualisieren |
 |-------|------|-------------------|
 | `PLATFORM_ROADMAP.md` | EINZIGE Planungs-Datei. Alle Phasen, Tasks, Architekturentscheidungen | Bei Planungsänderungen |
 | `PROGRESS.md` | Fortschritts-Tracking. Pro Task: Status, Forgejo Issue, Verifiziert | Bei jedem Task-Status-Wechsel |
 ### Task-Status-Verwaltung
 Jeder Task in der Roadmap hat einen Status der in `PROGRESS.md` verfolgt wird:
 - `not_started` — Task noch nicht begonnen
 - `in_progress` — Task wird bearbeitet
 - `blocked` — Task blockiert (Abhängigkeit fehlt, Entscheidung ausstehend)
 - `review` — Task implementiert, wartet auf Review/Tests
 - `done` — Task hat Definition of Done (DoD) erfüllt
 **Der Agent MUSS `PROGRESS.md` bei jedem Status-Wechsel aktualisieren.** Kein Task-Wechsel ohne PROGRESS.md-Update.
 ### Forgejo Issues & Milestones
 - **Pro Phase (A-J):** Ein Forgejo Milestone (z.B. "Phase A — Stabilität", "Phase B — System-Konsolidierung")
 - **Pro Task:** Ein Forgejo Issue mit Label `task` + Milestone der jeweiligen Phase
 - **Pro Bug:** Ein Forgejo Issue mit Label `bug` + Priorität (`critical`, `high`, `medium`, `low`)
 - **Pro Feature-Request:** Ein Forgejo Issue mit Label `enhancement`
 **Der Agent MUSS für jeden Task ein Forgejo Issue erstellen** und die Issue-Nummer in `PROGRESS.md` eintragen.
 ### Commit-Messages
 - Commit-Messages enthalten die Task-ID: `feat(B-LLM): zentraler LLM Client implementiert`
 - Bug-Fixes referenzieren das Issue: `fix(#123): Redis-Connection-Leak behoben`
 - `fixes #123` oder `closes #123` im Commit schließt das Issue automatisch
 ### Definition of Done (DoD)
 Ein Task gilt erst als **DONE** wenn alle 8 DoD-Kriterien erfüllt sind (siehe `PLATFORM_ROADMAP.md`). Ein Task ohne Test ist NICHT done. Der Agent darf keinen Task als `done` markieren ohne DoD erfüllt zu haben.
 ### Phase-Gate-Review
 Eine Phase gilt erst als **ABGESCHLOSSEN** wenn alle 7 Phase-Gate-Kriterien erfüllt sind (siehe `PLATFORM_ROADMAP.md`). Der Agent darf nicht zur nächsten Phase übergehen ohne Phase-Gate-Review bestanden zu haben.

 # Coolify Setup — CRM System v1.0
 Production deployment guide for the **CRM System** to the Coolify PaaS instance
 at `server.media-on.de` (server UUID `lw80w8scs4044gwcw084s00s4`).
 The deploy consists of **three Coolify resources** in the same project/environment:
 1. A **PostgreSQL 16** database resource (one-click or Docker image).
 2. The **crm-app** Application (Dockerfile build from a Git repository).
 3. The **crm-worker** Application (same Dockerfile build, different entrypoint).
 The resources talk to each other over the internal Docker network. The app
 is exposed publicly on `https://crm.media-on.de:443` (Let's Encrypt via Coolify).
 The worker is not exposed publicly — it only needs Redis and PostgreSQL access.
 ---
 ## 0. ⚠️ Critical domain-format gotcha
 Coolify's per-application **Domain field must contain an explicit port** in the
 URL. If you enter the domain without `:443`, Let's Encrypt certificate issuance
 will silently fail and Traefik will not route traffic correctly.
 ```
 ✅  https://crm.media-on.de:443
 ❌  https://crm.media-on.de
 ❌  crm.media-on.de
 ```
 > The same rule applies in the Coolify API: when calling
 > `PATCH /api/v1/applications/{uuid}` you must set
 > `{"domains": "https://crm.media-on.de:443"}` (note the `:443` suffix).
 > This is a known bug-fix from earlier deployments — never drop the port.
 ---
 ## 1. Prerequisites
 - Coolify server reachable at `https://server.media-on.de`, API token created
  in *Keys & Tokens → API tokens* (Bearer token, scope: `*`).
 - The DNS **A record** for `crm.media-on.de` points to the public IP of the
  Coolify server (Traefik will answer on `:443` and route by `Host` header).
 - The CRM source code lives in a **Forgejo repository** that Coolify can
  clone. Suggested location:
  `https://forge.media-on.de/leopoldadmin/crm-system` (branch `master`).
  > If the repo does not exist yet, create it and push the project:
  > ```bash
  > # One-time: create the repo via Forgejo API or UI
  > git remote add origin https://leopoldadmin:<TOKEN>@forge.media-on.de/leopoldadmin/crm-system.git
  > git push -u origin master
  > ```
 - You have the **internal host:port** of the Postgres resource that will be
  provisioned in step 2 (Coolify will print it, e.g. `abc123-postgres:5432`).
 ---
 ## 2. Resource A — PostgreSQL 16 database
 In the Coolify UI:
 1. Go to **Databases → + Add**.
 2. Choose **PostgreSQL 16** (Alpine).
 3. Configuration:
   - **Name**: `crm-postgres`
   - **Database name**: `crm_db`
   - **User**: `crm_user`
   - **Password**: *(generate a strong one — see Secret generation below)*
   - **Public accessibility**: **disabled** (only the crm-app talks to it)
 4. Click **Deploy** and wait for status `running:healthy`.
 5. Note the **internal host:port** Coolify exposes (typically
   `<resource-uuid>-postgres:5432`). You will need it in step 3.
 > **Alternative (API):**
 > ```bash
 > curl -X POST http://server.media-on.de/api/v1/databases \
 >   -H "Authorization: Bearer $COOLIFY_TOKEN" \
 >   -H "Content-Type: application/json" \
 >   -d '{"type":"postgresql","project_uuid":"...","environment_name":"production",
 >        "server_uuid":"lw80w8scs4044gwcw084s00s4",
 >        "name":"crm-postgres","postgres_user":"crm_user",
 >        "postgres_password":"<STRONG_PASSWORD>",
 >        "postgres_db":"crm_db","is_public":false}'
 > ```
 ---
 ## 3. Resource B — crm-app (Dockerfile build)
 In the Coolify UI:
 1. **Projects → + Add Project** if you don't have one yet (e.g. `CRM`).
 2. **Environment → + Add Environment** → name: `production`.
 3. Inside that environment, **+ Add → Application → Public/Private Repository**.
 4. Fill in:
   - **Git repository**: `https://forge.media-on.de/leopoldadmin/crm-system`
   - **Branch**: `master`
   - **Build pack**: `Dockerfile`
   - **Dockerfile location**: `Dockerfile` (default, repo root)
   - **Port**: `8000`
 5. Click **Deploy** once to let Coolify create the resource (it will fail to
   start without environment variables — that's expected).
 6. Note the **Application UUID** (visible in the URL or via
   `GET /api/v1/applications`).
 ---
 ## 4. Environment variables (on the crm-app resource)
 In **crm-app → Environment Variables**, set:
 | Key | Value | Notes |
 |-----|-------|-------|
 | `DATABASE_URL` | `postgresql+asyncpg://crm_user:<PW>@<postgres-internal-host>:5432/crm_db` | Use the internal host from step 2 (e.g. `crm-postgres-xyz:5432`), **not** `localhost` and **not** the public DNS. |
 | `AUTH_SECRET` | *see secret generation* | **MUST be ≥ 32 chars.** |
 | `CORS_ORIGINS` | `https://crm.media-on.de:443` | Comma-separated, no wildcards, must match the domain where the browser actually loads the SPA. |
 | `ENVIRONMENT` | `production` | |
 | `LOG_LEVEL` | `INFO` | `DEBUG` only temporarily. |
 | `BCRYPT_ROUNDS` | `12` | Aligned with `.env.example`. |
 ### Secret generation (run once, locally)
 ```bash
 # AUTH_SECRET (min 32 chars, recommended 48+)
 python -c "import secrets; print(secrets.token_urlsafe(48))"
 # POSTGRES_PASSWORD (min 16 chars, recommended 24+)
 python -c "import secrets; print(secrets.token_urlsafe(24))"
 ```
 **Never commit these values.** Coolify stores them encrypted at rest, but they
 are still rendered in the UI to anyone with read access to the environment.
 > **Alternative (API — bulk update):**
 > ```bash
 > curl -X PATCH http://server.media-on.de/api/v1/applications/$APP_UUID/envs/bulk \
 >   -H "Authorization: Bearer $COOLIFY_TOKEN" \
 >   -H "Content-Type: application/json" \
 >   -d '{
 >     "data": [
 >       {"key":"DATABASE_URL",        "value":"postgresql+asyncpg://crm_user:<PW>@<PG_HOST>:5432/crm_db"},
 >       {"key":"AUTH_SECRET",          "value":"<TOKEN_URLSAFE_48>"},
 >       {"key":"CORS_ORIGINS",         "value":"https://crm.media-on.de:443"},
 >       {"key":"ENVIRONMENT",          "value":"production"},
 >       {"key":"LOG_LEVEL",            "value":"INFO"},
 >       {"key":"BCRYPT_ROUNDS",        "value":"12"}
 >     ]
 >   }'
 > ```
 ---
 ## 5. Configure the public domain (with port!)
 In **crm-app → Domains → + Add Domain**:
 - **Domain**: `https://crm.media-on.de:443`
  - ⚠️ **Port `:443` is mandatory.** See section 0.
 - **Let's Encrypt**: **enabled** (default).
 - Click **Save**. Coolify will issue the certificate and reload Traefik.
 > **Alternative (API):**
 > ```bash
 > curl -X PATCH http://server.media-on.de/api/v1/applications/$APP_UUID \
 >   -H "Authorization: Bearer $COOLIFY_TOKEN" \
 >   -H "Content-Type: application/json" \
 >   -d '{"domains": "https://crm.media-on.de:443"}'
 > ```
 ---
 ## 6. Healthcheck (Coolify side)
 In **crm-app → Advanced → Healthcheck**:
 - **Healthcheck path**: `/api/v1/health`
 - **Healthcheck method**: `GET`
 - **Healthcheck interval**: `30s`
 - **Healthcheck timeout**: `10s`
 - **Healthcheck retries**: `3`
 - **Healthcheck start period**: `15s`
 > The Dockerfile's in-container `HEALTHCHECK` is the source of truth for
 > Docker-level health. The Coolify/Traefik healthcheck is what drives
 > automatic rollbacks and load-balancer routing. Set both, identically.
 ---
 ## 7. Build & deploy
 In the Coolify UI: **crm-app → Deployments → Deploy**.
 Watch the build log. The first deploy will:
 1. Clone the repo (branch `master`).
 2. Build the multi-stage Dockerfile (≈ 1–2 min, depending on cache).
 3. Start the container. `prestart.sh` runs `alembic upgrade head` against the
   Postgres database.
 4. Uvicorn binds to `0.0.0.0:8000` and starts serving.
 A healthy deploy ends with the container status `running:healthy`.
 > **Alternative (API):**
 > ```bash
 > curl -X POST http://server.media-on.de/api/v1/deploy \
 >   -H "Authorization: Bearer $COOLIFY_TOKEN" \
 >   -H "Content-Type: application/json" \
 >   -d "{\"uuid\":\"$APP_UUID\"}"
 > ```
 ---
 ## 8. Verification
 From anywhere with internet access:
 ```bash
 # 1. Root health (used by Docker HEALTHCHECK & Coolify healthcheck)
 curl -fsSL -o /dev/null -w "%{http_code}\n" https://crm.media-on.de:443/health
 # → 200
 # 2. API v1 health (mounted under the versioned router)
 curl -fsSL -o /dev/null -w "%{http_code}\n" https://crm.media-on.de:443/api/v1/health
 # → 200
 # 3. Frontend SPA (served by the static-files mount)
 curl -fsSL -o /dev/null -w "%{http_code} %{content_type}\n" \
  https://crm.media-on.de:443/index.html
 # → 200 text/html
 # 4. Interactive API docs
 # Open in a browser:  https://crm.media-on.de:443/docs
 # Register a user via POST /api/v1/auth/register
 # Login via POST /api/v1/auth/login → access_token
 # Use the token as `Authorization: Bearer <access_token>` on protected routes
 ```
 If any of these return `502` / `503` / `504`:
 - Check **crm-app → Logs** in Coolify (the UI is the only place with full
  stdout/stderr, the API does not expose logs).
 - Confirm the container is `running:healthy` (not `running:unhealthy`,
  `exited`, or `starting`).
 - Confirm the Postgres resource is `running:healthy` and the
  `DATABASE_URL` host matches its internal DNS name.
 For full incident response, see [`/a0/.a0/runbook-restore.md`](../../a0/runbook-restore.md).
 ---
 ## 9. Going forward — redeploys
 - **Code change** → push to `master` on Forgejo → **Deployments → Deploy** in
  Coolify. The Dockerfile layer-cache will reuse `pip install -r
  requirements.txt` if `requirements.txt` is unchanged.
 - **Environment variable change** → edit in Coolify UI (or `PATCH .../envs/bulk`
  via API) → **Deploy** (Coolify does *not* auto-restart on ENV change alone).
 - **Domain change** → use the API (`PATCH /api/v1/applications/{uuid}`) so it
  is reproducible; the UI is a fallback only.

 ## 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. |

 **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". |

 **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 |

 **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. |

 | 3.8 | Plugin-Entwickler-Richtlinien erstellen | 8h | `docs/plugin-development-guide.md`: Manifest-Format, Lifecycle, UI-Registrierung, Event-Bus, Migration-Runner, Service-Container, Beispiele, Do's & Don'ts, Testing-Guide. |
 | 3.9 | Plugin-Templates / Boilerplate | 4h | `templates/plugin-template/`: Minimal-Plugin als Startpunkt für neue Plugins. Mit Manifest, Routes, Models, Schemas, Migration, Tests. |
 | 3.10 | Tests für Plugin-UI-System | 4h | Vitest-Tests für PluginRegistry, PluginLoader, dynamische Sidebar/Settings. |
 | 3.10b | Plugin-Install-System | 8h | Plugins einfach installierbar machen: ZIP-Upload, URL-Install, Plugin-Marketplace-Integration. Plugin-Upload-Endpoint, Validierung (Manifest prüfen, tenant_id-Check, Security-Scan), automatische Migration bei Install. Install-UI in SettingsPlugins.tsx. |
 **Phase 3 Gesamt: ~58h**

 ### PHASE 3.5: Automation & Agents Plugin
 **Ziel:** Zentrale Oberfläche für Automatisierungen und selbst-arbeitende KI-Agenten. Plugins können Agenten und Automation-Templates mitbringen.
 **Architektur:**

 ```
 | # | 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. |

 | 3.26 | 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. |

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)

 ## 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)
 - ✅ Cross-Imports: 224, Contracts: 8, get_contract: 11 — unverändert
 ---

 ---
 ## Phase 1: Contracts konsequent nutzen (Punkte 1-3)
 **Ziel:** Alle 224 direkten Cross-Plugin-Imports werden durch das Contract-System ersetzt.
 ### 1.1 Fehlende contracts.py erstellen (7 Std)
 Für jedes Plugin, das noch keine `contracts.py` hat, eine erstellen:
 | # | Plugin | Exportierte Symbole | Aufwand |
 |---|---|---|---|
 | 1 | `ai_proactive` | ContextTools, ProactiveAgent, JobScheduler | 30 Min |
 | 2 | `ai_ui_control` | WebSocketManager, UIAction | 30 Min |
 | 3 | `automation` | AgentRunner, ExecutionEngine, Scheduler, WorkflowTimeout | 45 Min |
 | 4 | `entity_links` | EntityLink model, create_link, get_links | 20 Min |
 | 5 | `forgejo_error_reporter` | report_error_to_forgejo | 15 Min |
 | 6 | `mcp_client` | McpClient, McpServerConfig | 30 Min |
 | 7 | `mcp_server` | McpServer, ToolDefinitions | 30 Min |
 | 8 | `report_generator` | ReportTemplate, ReportInstance, PdfGenerator | 30 Min |
 | 9 | `system_notif` | SystemNotifHandler | 15 Min |
 | 10 | `tags` | Tag, TagAssignment, assign_tags, remove_tags | 20 Min |
 | 11 | `tasks` | Task, TaskService, create_task, update_task | 30 Min |
 | 12 | `test_sample` | TestSamplePlugin | 10 Min |
 | 13 | `dms` (erweitern) | File, Folder, UploadService, DownloadService | 30 Min |
 | 14 | `permissions` (erweitern) | ShareLink, PermissionResolver | 30 Min |
 **Schema für jede contracts.py:**
 ```python
 """Public contract for the <plugin> plugin."""
 from __future__ import annotations
 from app.plugins.builtins.contracts import get_contract_registry
 # Import only public symbols from internal modules
 class <Plugin>Contract:
    contract_name = "<plugin>"
    # Expose only public API
 _contract = <Plugin>Contract()
 get_contract_registry().register("<plugin>", _contract)
 ```
 ### 1.2 Direkte Imports ersetzen (28 Std)
 224 direkte Imports müssen durch `get_contract()` ersetzt werden.
 **Top-Priorität (häufigste Import-Quellen):**
 | # | Datei | Imports | Aufwand |
 |---|---|---|---|
 | 1 | `automation/plugin.py` | 10 | 1,5 Std |
 | 2 | `automation/routes.py` | 8 | 1,5 Std |
 | 3 | `ai_proactive/services.py` | 8 | 1,5 Std |
 | 4 | `ai_proactive/plugin.py` | 8 | 1,5 Std |
 | 5 | `unified_search/jobs.py` | 7 | 1 Std |
 | 6 | `builtins/__init__.py` | 7 | 1 Std |
 | 7 | `ai_proactive/jobs.py` | 7 | 1 Std |
 | 8 | `ai_assistant/participant_handler.py` | 7 | 1 Std |
 | 9 | `kommunikation/routes.py` | 6 | 1 Std |
 | 10 | `kommunikation/contracts.py` | 6 | 1 Std |
 | 11 | `automation/agent_routes.py` | 6 | 1 Std |
 | 12 | `automation/agent_comm.py` | 6 | 1 Std |
 | 13 | `ai_proactive/participant_handler.py` | 6 | 1 Std |
 | 14 | `ai_assistant/plugin.py` | 6 | 1 Std |
 | 15 | `unified_search/routes.py` | 5 | 45 Min |
 | 16-50 | Alle übrigen Dateien | ~122 | 12 Std |
 **Muster für Ersetzung:**
 ```python
 # VORHER (direkt):
 from app.plugins.builtins.kommunikation.services import send_message
 # NACHHER (über Contract):
 from app.plugins.builtins.contracts import get_contract
 async def my_function(db, ...):
    komm = get_contract("kommunikation")
    if komm:
        await komm.send_message(db, ...)
    # Graceful degradation wenn Plugin nicht aktiv
 ```
 ### 1.3 Contracts bei Deaktivierung abmelden (4 Std)
 In jedem Plugin's `on_deactivate()`:
 ```python
 async def on_deactivate(self, db, service_container, event_bus) -> None:
    # Contract abmelden
    from app.plugins.builtins.contracts import get_contract_registry
    get_contract_registry().unregister(self.manifest.name)
    # ... rest of cleanup
    await super().on_deactivate(db, service_container, event_bus)
 ```
 | # | Plugin | Aufwand |
 |---|---|---|
 | 1-16 | Alle 16 Plugins | 15 Min pro Plugin = 4 Std |
 ### 1.4 Tests anpassen (8 Std)
 - Cross-Plugin-Tests müssen mit Contracts laufen
 - `test_plugins.py` — Contract-Registry Tests
 - `test_contracts.py` — Neue Test-Datei für Contract-System
 - Alle Integrationstests mit Contract-Mocks
 ### Meilenstein Phase 1:
 - ✅ Alle 16 Plugins haben contracts.py
 - ✅ 0 direkte Cross-Plugin-Imports (geprüft mit grep)
 - ✅ Contracts werden bei Deaktivierung abgemeldet
 - ✅ Alle Tests bestanden
 ---
 ## Phase 2: Hooks/Filters-System (Punkt 4)
 **Ziel:** WordPress-Style Hooks (actions + filters) für Plugin-Erweiterbarkeit.
 ### 2.1 HookRegistry erstellen (4 Std)
 **Neue Datei: `app/core/hooks.py`**
 ```python
 """WordPress-style hooks: actions (fire-and-forget) and filters (modify data)."""
 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
            import sys
            sys.path.insert(0, str(external_dir))
            try:
                module = importlib.import_module(f"{plugin_dir.name}.plugin")
                # ... find BasePlugin subclass ...
            finally:
                sys.path.remove(str(external_dir))
        return discovered
 ```
 ### 5.2 Plugin-Signatur-Validierung (8 Std)
 **Neue Datei: `app/plugins/signature.py`**
 ```python
 """Plugin signature verification for external plugins."""
 from pathlib import Path
 import hashlib
 import hmac
 # Ed25519 oder HMAC-SHA256 Signatur
 class PluginSignature:
    """Verify plugin package signatures."""
    @staticmethod
    def verify_signature(zip_path: Path, signature: bytes, public_key: bytes) -> bool:
        """Verify Ed25519 signature of plugin ZIP."""
        # 1. Read ZIP content
        # 2. Compute hash
        # 3. Verify signature with public key
        pass
    @staticmethod
    def compute_hash(zip_path: Path) -> bytes:
        """Compute SHA-256 hash of plugin ZIP."""
        pass
    @staticmethod
    def sign_plugin(zip_path: Path, private_key: bytes) -> bytes:
        """Sign a plugin ZIP (for plugin authors)."""
        pass
 ```
 ### 5.3 Plugin-Allowlist (4 Std)
 **Neue Alembic-Migration: `0044_plugin_allowlist.py`**
 ```python
 # Tabelle: plugin_allowlist
 # - id: UUID
 # - plugin_name: VARCHAR(80)
 # - allowed_hash: VARCHAR(64)  # SHA-256
 # - allowed_signature: TEXT    # Ed25519 signature
 # - added_by: UUID (user)
 # - created_at: TIMESTAMPTZ
 # - is_active: BOOLEAN

 ---
 ## 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]
    settings_pages: list[FrontendSettingsPage]
    dashboard_widgets: list[FrontendDashboardWidget]
    agent_definitions: list[AgentDefinitionContribution]

    heartbeat_configs: list[HeartbeatConfigContribution]
    miniapps: list[MiniAppContribution]
    custom_fields: list[CustomFieldDefinition]
    model_config = {"extra": "forbid"}
 ```
 **Neue Felder hinzufügen:**
 ```python
 class PluginManifest(BaseModel):
    # ... alle bestehenden Felder ...
    # ── Versioning (Phase 4) ──
    min_app_version: str = Field(
        default="0.0.0",
        description="Minimum LeoCRM version required (SemVer)"
    )
    # ── Marketplace (Phase 5) ──
    author: str = Field(default="", max_length=200, description="Plugin author name")
    author_email: str = Field(default="", max_length=200, description="Author contact email")
    homepage: str = Field(default="", max_length=500, description="Plugin homepage URL")
    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 |
 | 3 | `ai_ui_control` | 20 Min | author, min_app_version, contract_version |
 | 4 | `automation` | 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 |
 ---

 Nach Abschluss aller 5 Phasen:
 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
 5. ✅ **Plugin-Isolation** durch Linting-Regeln erzwungen
 6. ✅ **SemVer-Vergleich** statt String-Vergleich
 7. ✅ **Rollback-Migrationen** für alle Plugins verfügbar
 8. ✅ **min_app_version** wird bei Installation geprüft
 9. ✅ **Update-Benachrichtigung** im Frontend
 10. ✅ **Marketplace-Endpoint** vorbereitet (deaktiviert)
 11. ✅ **Signatur-Validierung** für externe Plugins
 12. ✅ **Allowlist** schützt vor nicht autorisierten Plugins
 13. ✅ **Externe Plugin-Discovery** funktioniert
 14. ✅ **Alle Tests bestanden**
 15. ✅ **Built-in Plugins laufen ohne Marketplace**
 16. ✅ **PluginManifest hat alle neuen Felder** (min_app_version, author, hooks, contract_version, etc.)
 17. ✅ **Alle 19 Plugin-Manifeste aktualisiert** mit neuen Feldern
 18. ✅ **Manifest-Validierung verschärft** (SemVer, Hook-Names)
 19. ✅ **Frontend-Typen aktualisiert** für neue Manifest-Felder

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

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

 # LeoCRM UI-Overhaul-Plan (v2)
 > **Erstellt:** 2026-08-21
 > **Aktualisiert:** 2026-08-21 — AI Assistent Integration hinzugefügt
 > **Status:** Planung — nicht gestartet
 > **Leitlinie:** Auf bestehendem Code aufbauen, 3-Spalten-Explorer-Layout als Standard, keine parallelen Systeme
 ---
 ## Standard-Layout (Referenz: ContactsList.tsx)
 Alle Explorer-Plugins nutzen das 3-Spalten-Layout aus den UI-Design-Guidelines:
 ```
 ┌─────────────┬──────────────────┬──────────────────────┐
 │   Tree      │   Liste/Ansicht   │   Detail             │
 │  (224px)    │   (flex-1)        │   (flex-1 / 60%)     │
 │ ResizablePanel│  ResizablePanel   │   ResizablePanel     │
 └─────────────┴──────────────────┴──────────────────────┘
 ```
 - **Toolbar oben:** PluginToolbar mit Filter-Dropdowns, Ansichts-Umschaltern, Aktion-Buttons
 - **Linke Spalte:** ResizablePanel mit Baumansicht (Ordner, Kategorien, Kalender)
 - **Mitte:** Liste, Karten, Kalender-Ansicht — mehrere Ansichten umschaltbar
 - **Rechts:** Detail-Bereich für ausgewähltes Element
 ---
 ## Phase 1: Echte Bugs fixen (2-3 Tage)
 ### 1.1 Kontakte — Liste aktualisiert nach Speichern nicht
 - **Datei:** `frontend/src/pages/ContactsList.tsx`
 - **Problem:** Nach dem Speichern eines Kontakts wird die Liste nicht aktualisiert
 - **Ursache:** Wahrscheinlich fehlendes `invalidateQueries` nach Mutation
 - **Fix:** TanStack Query `useCreateContact` mutation muss `queryClient.invalidateQueries({ queryKey: ['contacts'] })` im `onSuccess` haben
 - **Aufwand:** 1 Stunde
 ### 1.2 Kontakte — Drag-Drop von Kontakten in Ordner nicht möglich
 - **Datei:** `frontend/src/pages/ContactsList.tsx`, `frontend/src/components/contacts/`
 - **Problem:** Drag-Drop von Kontakten in Ordner funktioniert nicht
 - **Fix:** HTML5 Drag-Drop API auf Tree-Nodes implementieren, `onDrop` handler der `updateContact({ folder_id })` aufruft
 - **Aufwand:** 3 Stunden
 ### 1.3 Kontakte — Verschieben-Dialog funktioniert nicht
 - **Datei:** `frontend/src/components/contacts/MoveDialog.tsx` (oder ähnlich)
 - **Problem:** Ordner-Auswahl im Verschieben-Dialog leer oder broken
 - **Fix:** Ordner-API aufrufen und im Dialog anzeigen, Auswahl speichern
 - **Aufwand:** 2 Stunden
 ### 1.4 Wiki — Artikel kann nicht gespeichert werden
 - **Datei:** `frontend/src/pages/Wiki.tsx`, `frontend/src/api/knowledge.ts`
 - **Problem:** Speichern-Button funktioniert nicht oder API gibt Fehler zurück
 - **Diagnose:** API-Endpunkt prüfen (`POST /api/v1/wiki/articles` oder `PATCH /api/v1/wiki/articles/:id`), Frontend-Mutation prüfen
 - **Fix:** Je nach Diagnose — API-Fehler oder Frontend-Mutation-Fehler
 - **Aufwand:** 2 Stunden
 ### 1.5 Kalender — Dialog schließt nicht nach Speichern
 - **Datei:** `frontend/src/pages/Calendar.tsx`, `frontend/src/components/calendar/AppointmentEditForm.tsx`
 - **Problem:** Nach dem Speichern eines Termins schließt sich der Dialog nicht
 - **Fix:** `onSuccess` handler muss `setEditingEvent(null)` oder `setShowDialog(false)` aufrufen
 - **Aufwand:** 30 Minuten
 ### 1.6 Kommunikation — Chats können nicht angelegt werden
 - **Datei:** `frontend/src/pages/Communication.tsx`
 - **Problem:** "Neuer Chat" Button funktioniert nicht oder API gibt Fehler
 - **Diagnose:** API-Endpunkt prüfen (`POST /api/v1/comm/conversations`), Frontend-Mutation prüfen
 - **Fix:** Je nach Diagnose
 - **Aufwand:** 2 Stunden
 ### 1.7 Wiki — Doppelt im Menü
 - **Datei:** `frontend/src/routes/index.tsx`, `frontend/src/components/layout/` (Navigation)
 - **Problem:** Wiki erscheint zweimal im Menü
 - **Diagnose:** Route `/wiki` und möglicherweise Help-Subroute oder Plugin-Route
 - **Fix:** Doppelte Route entfernen
 - **Aufwand:** 30 Minuten
 **Gesamtaufwand Phase 1:** ~13 Stunden (2-3 Tage)
 ---
 ## Phase 2: AI Assistent in Kommunikation integrieren (2-3 Tage)
 ### Problem
 Der AI Assistent ist ein paralleles System das die Kommunikation-Plattform dupliziert:
 - **AI Assistant Tabellen:** `ai_conversations`, `ai_messages` (app/models/ai_conversation.py) + `ai_chat_sessions`, `ai_chat_messages`, `ai_chat_attachments` (app/plugins/builtins/ai_assistant/models.py) — 5 Tabellen
 - **AI Assistant Frontend:** `AIAssistant.tsx`, `AIAssistantStandalone.tsx`, `SessionList.tsx`, `ChatWindow.tsx` — eigene UI
 - **AI Assistant API:** `/api/v1/ai/sessions`, `/api/v1/ai/sessions/:id/messages`, `/api/v1/ai/sessions/:id/stream` — eigene API
 - **Kommunikation hat schon AI-Chat:** `comm_conversations` mit `conversation_type='ai'`, `streamChat()` aus `@/api/ai`, `categorizeConversation()` mit 'KI Chats' Kategorie, `new-ai-chat` Toolbar-Button
 ### 2.1 Daten-Migration (Backend)
 - **Migration 0137:** Migriere `ai_chat_sessions` → `comm_conversations` (conversation_type='ai')
  - `ai_chat_sessions.id` → `comm_conversations.id`
  - `ai_chat_sessions.title` → `comm_conversations.title`
  - `ai_chat_sessions.tenant_id` → `comm_conversations.tenant_id`
  - `ai_chat_sessions.user_id` → `comm_conversations.owner_id`
  - `ai_chat_sessions.agent_id` → `comm_conversations.metadata.agent_id`
  - `ai_chat_sessions.created_at` → `comm_conversations.created_at`
 - **Migration 0137:** Migriere `ai_chat_messages` → `comm_messages`
  - `ai_chat_messages.id` → `comm_messages.id`
  - `ai_chat_messages.session_id` → `comm_messages.conversation_id`
  - `ai_chat_messages.role` → `comm_messages.sender_type` ('user' → 'user', 'assistant' → 'ai')
  - `ai_chat_messages.content` → `comm_messages.content`
  - `ai_chat_messages.tenant_id` → `comm_messages.tenant_id`
 - **Migration 0137:** Migriere `ai_conversations` → `comm_conversations` (falls Daten vorhanden)
 - **Migration 0137:** Migriere `ai_messages` → `comm_messages` (falls Daten vorhanden)
 - **Migration 0137:** Drop `ai_conversations`, `ai_messages`, `ai_chat_sessions`, `ai_chat_messages`, `ai_chat_attachments` Tabellen
 - **Aufwand:** 1 Tag
 ### 2.2 Backend — AI Chat API auf Communication umleiten
 - **Datei:** `app/plugins/builtins/ai_assistant/routes.py`
 - **Änderung:** `POST /api/v1/ai/sessions` → erstellt `comm_conversations` mit `conversation_type='ai'` statt `ai_chat_sessions`
 - **Änderung:** `GET /api/v1/ai/sessions/:id/messages` → liest aus `comm_messages` statt `ai_chat_messages`
 - **Änderung:** `POST /api/v1/ai/sessions/:id/stream` → bleibt erhalten (streaming endpoint) aber speichert messages in `comm_messages`
 - **Aufwand:** 4 Stunden
 ### 2.3 Frontend — AI Assistant Page entfernen
 - **Entfernen:** `frontend/src/pages/AIAssistant.tsx`
 - **Entfernen:** `frontend/src/pages/AIAssistantStandalone.tsx`
 - **Entfernen:** `frontend/src/components/ai/SessionList.tsx`
 - **Entfernen:** `frontend/src/components/ai/ChatWindow.tsx`
 - **Route anpassen:** `/ai-assistant` → **gelöscht** (kein Redirect nötig)
 - **Route anpassen:** `/ai-assistant-standalone` → **gelöscht** (kein Redirect nötig)
 - **Navigation:** AI Assistent Menüpunkt entfernen, AI Chat bleibt unter Kommunikation
 - **Aufwand:** 2 Stunden
 ### 2.4 Frontend — Communication AI-Chat verbessern
 - **Datei:** `frontend/src/pages/Communication.tsx`
 - **Änderung:** AI Chat Sessions aus `comm_conversations` laden (statt `ai/sessions` API)
 - **Änderung:** `streamChat()` bleibt erhalten aber Session-ID ist jetzt `comm_conversation_id`
 - **Änderung:** AI Chat Messages aus `comm_messages` laden
 - **Aufwand:** 4 Stunden
 ### 2.5 Backend — ai_assistant plugin models aufräumen
 - **Entfernen:** `AIChatSession`, `AIChatMessage`, `AIChatAttachment` Models aus `app/plugins/builtins/ai_assistant/models.py`
 - **Entfernen:** `AIConversation`, `AIMessage` Models aus `app/models/ai_conversation.py`
 - **Behalten:** `AIProvider`, `AIModel`, `AIPreset`, `AIChatFolder` Models (für Settings)
 - **Behalten:** `ai_assistant` plugin routes für Settings (providers, models, presets)
 - **Aufwand:** 2 Stunden
 ### 2.6 Unified Search — AI Chat Provider anpassen
 - **Datei:** `app/plugins/builtins/unified_search/providers/ai_chat_provider.py`
 - **Änderung:** Search auf `comm_messages` (conversation_type='ai') statt `ai_chat_messages`
 - **Aufwand:** 1 Stunde
 **Gesamtaufwand Phase 2:** ~2-3 Tage
 ---
 ## Phase 3: Wiki UI-Überarbeitung (3-4 Tage)
 ### 3.1 WYSIWYG Editor
 - **Datei:** `frontend/src/components/wiki/WikiEditor.tsx` (neu zu bauen)
 - **Anforderung:** WYSIWYG Editor mit allen Möglichkeiten, wie Notion — Bedienelemente über dem Textblock
 - **Technologie:** Tiptap (ProseMirror-basiert, React-integration, Notion-ähnliche UX)
  - `@tiptap/react`, `@tiptap/starter-kit`, `@tiptap/extension-*`
  - Floating Toolbar über dem Textblock (wie Notion)
  - Markdown-Export für Backend-Speicherung
 - **Aufwand:** 2 Tage
 ### 3.2 Wiki Layout — 3-Spalten
 - **Datei:** `frontend/src/pages/Wiki.tsx` (umbauen)
 - **Anforderung:** Toolbar oben, links Baummenü (Kategorien), Mitte Textbereich
 - **Aufbau:**
  - **Toolbar:** View/Edit Mode Toggle (oben rechts), Suche, Neuer Artikel
  - **Links:** WikiBrowser (existiert schon) — Baumansicht mit Kategorien

 ## Zusammenfassung
 | Phase | Inhalt | Aufwand | Migration | Abhängigkeit |
 |-------|--------|---------|-----------|-------------|
 | 1 | Echte Bugs fixen | 2-3 Tage | Keine | Keine |
 | 2 | AI Assistent → Kommunikation | 2-3 Tage | 0137 | Phase 1.6 |
 | 3 | Wiki UI + WYSIWYG | 3-4 Tage | Keine | Phase 1.4 |
 | 4 | Tasks UI neu | 2-3 Tage | Keine | Keine |
 | 5 | Kalender UI | 1 Tag | Keine | Phase 1.5 |
 | 6 | Tags Umstrukturierung | 2 Tage | 0138 | Keine |
 | 7 | Reports UI | 2 Tage | 0139 | Keine |
 | 8 | Kommunikation UI | 1-2 Tage | 0140 | Phase 2 |
 | 9 | Strukturelle Änderungen | 0.5 Tage | Keine | Keine |
 **Gesamtaufwand:** ~17-22 Tage
 ### Reihenfolge:
 1. **Phase 1** (Bugs) — zuerst, damit grundlegende Funktionen arbeiten
 2. **Phase 9** (Strukturelle Änderungen) — schnell, wenig Aufwand
 3. **Phase 5** (Kalender) — kleines Update, baut auf Phase 1 auf
 4. **Phase 2** (AI Assistent → Kommunikation) — entfernt paralleles System, baut auf Phase 1.6 auf
 5. **Phase 6** (Tags) — unabhängig, Backend + Frontend
 6. **Phase 4** (Tasks) — großer Umbau, unabhängig
 7. **Phase 3** (Wiki) — größter Umbau (WYSIWYG Editor), baut auf Phase 1 auf
 8. **Phase 7** (Reports) — großer Umbau, unabhängig
 9. **Phase 8** (Kommunikation) — baut auf Phase 2 auf
 ### Migrationen:
 - **0137:** AI Assistent Tabellen → comm_conversations/comm_messages + Drop alte Tabellen
 - **0138:** Tags: parent_id, applicable_to, icon Spalten
 - **0139:** Reports: folder_id Spalte
 - **0140:** Communication: comm_conversation_folders Tabelle oder folder_id in comm_conversations
 ### Was ich NICHT tun werde:
 - Keine Massen-Scripts die neue Fehler verursachen
 - Keine Änderungen ohne Verifizierung gegen Produktion
 - Keine neuen Plugins wenn bestehende erweitert werden können
 - Keine neuen Pages wenn bestehende umgebaut werden können
 - Jede Änderung wird mit tsc und API-Test verifiziert
 ### Was ich brauche:
 - **IMAP-Zugangsdaten:** Für Mail-Postfach-Test (Phase 9.2)

 This migration dynamically discovers every table in the ``public`` schema that

 """Drop tasks_contact_id_fkey — contact_id is now derived from entity_id (ARCH-F-2).
 The tasks table has both a contact_id FK column (referencing contacts) and
 polymorphic entity_type/entity_id columns. The code now derives contact_id
 from entity_id when entity_type='contact', and stores NULL in the FK column.
 The FK constraint is redundant and prevents creating tasks with arbitrary
 entity references. This migration drops the FK constraint but keeps the column
 for backward compatibility.

 """Core ReAct (Reasoning + Acting) loop for AI agents.
 Implements a true ReAct loop that alternates between LLM reasoning and tool
 execution. Each step records the thought (LLM content), action (tool name),
 action_input (tool arguments), and observation (tool result).
 The loop terminates when:
 - The LLM returns a final response without tool calls (completed)
 - max_steps is reached (stopped_max_steps)
 - timeout is exceeded (stopped_timeout)
 - A permanent error occurs (stopped_error)
 Error handling uses ``ErrorCategory`` from ``app.core.error_codes``:
 - TRANSIENT → retry the LLM call (up to 3 retries per step)
 - PERMANENT → stop the loop immediately
 - PARTIAL → continue with partial results
