 # 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)

 ## 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): ...

 ## 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

 # 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)

 - 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

 ### 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

 ## 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

 ## 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

 ## 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

 # 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

 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

 - Use text_editor:write for new files, text_editor:patch for updates
 - Read existing files before modifying
 - No Lorem Ipsum, no placeholder code
 - Follow existing patterns (SQLAlchemy 2.0, Pydantic v2, FastAPI APIRouter)
 - Each plugin must have manifest, plugin class, routes, models, schemas, migrations
 - Register plugins in `app/plugins/builtins/__init__.py`
 - Keep response under 50 lines
 - Report: files created, test count + pass/fail, coverage %

 **Coverage**: 85.92% for plugin modules (target: 85% ✅)
 **Migration**: 0003_plugin_system.py applied (plugins + plugin_migrations tables)
 ### Files Created (12 new)
 - app/plugins/__init__.py, manifest.py, base.py, registry.py, migration_runner.py
 - app/plugins/builtins/__init__.py, test_sample.py, migrations/0001_test_plugin.sql, migrations/0001_bad_migration.sql
 - app/models/plugin.py, app/schemas/plugin.py, app/services/plugin_service.py, app/routes/plugins.py

 5. AC11 assertion type (dict vs string for HTTPException detail)
 ### Verification (Orchestrator Independent)
 - pytest tests/test_plugins.py -v: 47/47 PASS

 # 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)

 - `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.

+## 4. Forbidden Patterns
-### Phasen-Plan
+### Backend
 - ❌ SQLite — PostgreSQL 16 only
 - ❌ Jinja2/server-side HTML rendering — API-only backend
 - ❌ Cross-tenant data access — ORM auto-filter must not be bypassed
 - ❌ Plaintext passwords — bcrypt cost=12
 - ❌ JWT auth — session-based with HttpOnly cookies only
 - ❌ Naive datetime — TIMESTAMPTZ only
 - ❌ Integer IDs — UUID only
 - ❌ Hard-delete without `?gdpr=true`
 - ❌ Manual tenant filter — ORM auto-filter handles it
 - ❌ Sync I/O in routes — use asyncpg, aiofiles
 - ❌ Raw SQL without tenant_id check
 - ❌ Secrets in code — env vars only
 - ❌ Unvalidated input — Pydantic schemas required
 - ❌ Missing audit log on mutations
 - ❌ Plugin tables without tenant_id
-#### v1 Core Phases (Phase 3 — Implementation)

 ### 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.

 ## 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 **two 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).
 The two 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).
 ---
 ## 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`. |
 | `JWT_ALGORITHM` | `HS256` | Aligned with `.env.example`. |
 | `JWT_EXPIRY_HOURS` | `24` | 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 $COOLIFY_TOKEN" \
 >   -H "Content-Type: application/json" \
 >   -d '{
 >     "data": [
 >       {"key":"DATABASE_URL",        "value":"postgresql+asyncpg://crm_user:<PW>@<PG_HOST>:5432/crm_db"},
 >       {"key":"AUTH_SECRET",          "value":"<TOKEN_URLSAFE_48>"},
 >       {"key":"CORS_ORIGINS",         "value":"https://crm.media-on.de:443"},
 >       {"key":"ENVIRONMENT",          "value":"production"},
 >       {"key":"LOG_LEVEL",            "value":"INFO"},
 >       {"key":"BCRYPT_ROUNDS",        "value":"12"},
 >       {"key":"JWT_ALGORITHM",        "value":"HS256"},
 >       {"key":"JWT_EXPIRY_HOURS",     "value":"24"}
 >     ]
 >   }'
 > ```
 ---
 ## 5. Configure the public domain (with port!)
 In **crm-app → Domains → + Add Domain**:
 - **Domain**: `https://crm.media-on.de:443`
  - ⚠️ **Port `:443` is mandatory.** See section 0.
 - **Let's Encrypt**: **enabled** (default).
 - Click **Save**. Coolify will issue the certificate and reload Traefik.
 > **Alternative (API):**
 > ```bash
 > curl -X PATCH http://server.media-on.de/api/v1/applications/$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**: `/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.

 ### Pagination
 All list endpoints support pagination with `page` and `page_size` parameters.
 `page_size` is capped at **100** — values >100 return HTTP 422.
 ### CSV Export
 Contacts and companies support streaming CSV export via `/export?format=csv`.
 Uses `StreamingResponse` — does not buffer the entire file in memory.

 ## Monitoring
 ### Health Checks
 ```bash
 # Liveness
 curl http://localhost:8000/health/live
 # → {"status":"alive"}
 # Readiness
 curl http://localhost:8000/health/ready
 # → {"status":"ready","checks":{"database":"ok","redis":"ok","storage":"ok"}}
 # Full health
 curl http://localhost:8000/api/v1/health
 # → {"status":"healthy","version":"1.0.0","checks":{...}}
 ```
 ### Prometheus Metrics
 ```bash
 # Requires admin authentication
 curl -b "leocrm_session=<session>" http://localhost:8000/api/v1/metrics
 ```
 Available metrics:
 - `leocrm_http_requests_total` — Total HTTP requests
 - `leocrm_http_request_duration_seconds` — Request duration histogram
 - `leocrm_db_pool_connections` — Database connection pool size
 - `leocrm_arq_jobs_total` — Total ARQ background jobs
 ### System Dashboard
 Admin-only dashboard at `/system-dashboard` in the WebUI. Shows:
 - System Health, DB Stats, Redis Stats, Worker Queue
 - API Stats (total requests, error rate, avg response time)
 - Plugin Stats (discovered, active)
 - Storage Stats (disk usage, file count)
 - Alert Feed (system messages from Communication-System)
 ### Structured Logging
 LeoCRM uses `structlog` for structured JSON logging. All API requests are logged with:
 `timestamp`, `level`, `event`, `method`, `path`, `status`, `duration_ms`, `tenant_id`.
 ## Environment Profiles
 | Profile | `ENVIRONMENT` | Use Case |
 |---|---|---|
 | Development | `development` | Local dev (auto-reload, verbose logging) |
 | Testing | `testing` | Test suite (separate test DB, minimal logging) |
 | Production | `production` | Docker/Coolify deployment (JSON logging, secure cookies) |
 See [docs/admin-guide.md](docs/admin-guide.md#environment-profiles) for profile details.
 ## Testing
 ```bash
 # Run all tests
 pytest -v --tb=short
 # Run specific test suites
 pytest tests/test_monitoring.py tests/test_performance.py tests/test_health.py -v
 # Run with coverage
 pytest --cov=app --cov-report=term-missing
 # Run specific test file
 pytest tests/test_auth.py -v
 # Stop on first failure (for debugging)
 pytest -x
 ```

 # 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`

 **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)

 Create Date: 2026-07-23
 SAFE MIGRATION: When both company_id and contact_id columns exist in mails,
 company_id values are copied to contact_id (where contact_id IS NULL) before
 the column is dropped. A backup column is created to track which rows were
 originally linked to companies for safe downgrade.
 Changes:
 - UPDATE entity_links SET entity_type='contact' WHERE entity_type='company'
 - UPDATE tag_assignments SET entity_type='contact' WHERE entity_type='company'
 - UPDATE calendar_entry_links SET entity_type='contact' WHERE entity_type='company'
 - UPDATE addresses SET entity_type='contact' WHERE entity_type='company'
 - mails: copy company_id → contact_id WHERE contact_id IS NULL, then drop company_id

 This migration:
 1. Discovers all tables in the public schema that have a tenant_id column.
 2. ALTER TABLE ... FORCE ROW LEVEL SECURITY on each (ensures RLS applies to table owners too).
 3. Drops existing tenant_isolation policies and recreates them with both

 4. Covers core tables AND plugin tables (anything with tenant_id).

 """Normalize contact model: fix surfix typo, Float→Numeric(5,2) discounts, JSON→JSONB, unique constraints.
 Revision ID: 0039_contact_normalize
 Revises: 0038_dms_content_hash
 Create Date: 2026-07-25
 Changes:
 1. Rename column surfix → suffix on contacts table.
 2. Convert discount_* columns from Float to Numeric(5,2) with CHECK constraints (0-100).
 3. Convert custom columns from JSON to JSONB on contacts and contactpersons.
 4. Add partial unique constraints: (tenant_id, code) and (tenant_id, accounting_code) where NOT NULL.

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