-## 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":"..."}}

-Implement DMS (Document Management System) plugin as `app/plugins/builtins/dms/`.
-

-
-## 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,

-    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,

-);
-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

-## 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}

-- 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)

-## 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

-
-## 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/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)

-
-## Requirements
-- F-DMS-01–07: DMS file browser, folder tree, upload, preview, share, trash, search
-- F-FILEUI-01–06: File UI components (dropzone, preview modal, share dialog, bulk actions, trash view)
-- F-TAG-01–04: Tags UI (assign, bulk assign, tag cloud, tag picker)

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

-
-## 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
-

-
-## 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

 ## 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.**

-- **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`.

-### 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.

+- **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.

-| `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`

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

-### 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
-

-# LeoCRM — Implementationsplan: Fehlende Frontend-Features

-## ⚠️ 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

-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. |
-| 1.2 | `app/services/company_service.py` entfernen | 1h | 273 Zeilen. Importe aus `services/__init__.py` entfernen. |
-| 1.3 | `app/models/company.py` entfernen | 1h | Backward-compat shim. Importe überall auf `Contact` umstellen. |
-| 1.4 | `app/schemas/company.py` entfernen | 1h | CompanyCreate, CompanyUpdate, CompanyResponse etc. |
-| 1.5 | `app/ai/action_mapper.py` aktualisieren | 3h | Company-Intents (create_company, delete_company, update_company, list_company) auf Contact-API umstellen. Regex-Patterns anpassen. |
-| 1.6 | `app/workflows/engine.py` aktualisieren | 1h | Event `company.created` → `contact.created`. Workflow-Trigger anpassen. |
-| 1.7 | `app/core/worker.py` aktualisieren | 1h | `index_company` Referenzen → `index_contact`. |
-| 1.8 | `app/core/seeds.py` prüfen/aktualisieren | 1h | Falls Company-Seed-Daten existieren, auf Contact mit type='company' umstellen. |
-
-**1A Gesamt: ~10h**
-
-#### 1B: Backend — Plugins von entity_type='company' befreien
-
-| # | Aufgabe | Aufwand | Details |
-|---|---|---|---|
-| 1.9 | **entity_links Plugin** aktualisieren | 4h | `entity_type` Pattern von `^(company|contact)$` → `^contact$`. `company_router` entfernen. `on_company_deleted` → `on_contact_deleted`. Event `company.deleted` → `contact.deleted`. DB-Migration: bestehende EntityLinks mit entity_type='company' auf 'contact' migrieren. |

-## Empfohlene Reihenfolge
-
-```
-Phase 0 (Vorbereitung & Cleanup)
-    ↓
-Phase 1 (Unified Contact — Backend+Frontend)  ← Core-CRM-Feature, größte Phase
-    ↓
-Phase 2 (Code-Splitting & Performance)
-    ↓
-Phase 3 (Plugin-UI-System)  ← WordPress-Style, nicht zu lange schieben
-    ↓
-Phase 3.5 (Automation & Agents Plugin)  ← Agent Builder, Cron-Scheduler, Automation
-    ↓
-Phase 4 (KI-UI-Steuerung)  ← Baut auf Plugin-System auf
-    ↓
-Phase 5 (API-Vollständigkeit & Testbarkeit)  ← KI kann selbstständig testen
-    ↓
-Phase 6 (React Hook Form + Zod)  ← Qualität
-    ↓
-Phase 7 (Test-Vollendung)  ← Wartbarkeit für KI
-```
-
-**Begründung der Reihenfolge:**
-1. Phase 0 zuerst: Dependencies und Cleanup als Fundament
-2. Phase 1 als Nächstes: Core-CRM-Feature (Contacts) muss vollständig sein. Größte Phase (~74h) weil 'company' überall im Code verankert ist.
-3. Phase 2: Code-Splitting ist schnell und bringt sofortige Performance-Verbesserung
-4. Phase 3: Plugin-UI-System — je früher desto besser, sonst wird Umbau später schwieriger
-5. Phase 4: KI-UI-Steuerung baut auf Plugin-System auf (dynamische Routes, Tabs etc.). Bestehende WebSocket-Infrastruktur aus kommunikation Plugin als Referenz.
-6. Phase 5: API-Vollständigkeit und E2E-Tests für KI-Wartbarkeit
-7. Phase 6+7: Qualität und Test-Vollendung
-

-
-## Was bei der Überprüfung gefunden wurde
-
-### Phase 1 Korrektur: +41h Aufwand
-
-Die ursprüngliche Schätzung von 33h für Phase 1 war **massiv unterschätzt**. Die gründliche Code-Analyse zeigte:
-
-**'company' als entity_type ist in 6 Plugins verankert:**
-- `entity_links`: entity_type Pattern, company_router, on_company_deleted Event-Handler
-- `unified_search`: CompanySearchProvider, index_company, company.created/updated Events, search_engine Mapping
-- `calendar`: entity_type Pattern für EntryLinks
-- `tags`: entity_type Pattern für Tag-Assignments
-- `mail`: company_id Spalte in mails Tabelle (DB-Migration nötig!)
-- `ai/action_mapper`: Company-Intents (create/delete/update/list)
-
-**Event-Namen müssen migriert werden:**
-- `company.created` → `contact.created`
-- `company.updated` → `contact.updated`
-- `company.deleted` → `contact.deleted`
-- Betroffen: unified_search, entity_links, workflows, test_sample, manifest.py
-
-**DB-Migration nötig:**
-- `entity_links.entity_type = 'company'` → `'contact'`
-- `tag_assignments.entity_type = 'company'` → `'contact'`
-- `calendar_entry_links.entity_type = 'company'` → `'contact'`
-- `mails.company_id` → `mails.contact_id` (Spalte umbenennen)
-
-**Was NICHT geändert wird:**
-- `system_settings.company_name`, `company_street` etc. → Das ist die CRM-Besitzer-Firmeninfo für Rechnungen. Bleibt wie es ist.
-- `CalendarType = 'company'` → Das ist ein Kalender-Typ (Firmenkalender), keine Entity-Referenz. Kann bleiben.
-
-### Bestehende WebSocket-Infrastruktur
-Das `kommunikation` Plugin hat bereits eine vollständige WebSocket-Implementierung (`/api/v1/comm/ws`, `websocket_manager.py`). Diese kann als Referenz für die KI-UI-Steuerung (Phase 4) dienen — das spart Entwicklungszeit.
-
----
-
-## KI-Wartbarkeit: Schlüssel-Anforderungen
-
-Damit ein KI-Agent die App selbstständig warten kann:
-
-1. **Vollständige API-Abdeckung:** Jede UI-Funktion per API steuerbar (Phase 5)
-2. **E2E-Tests:** Playwright-Tests die KI ausführen kann (Phase 5)
-3. **API-Health-Check:** Script das alle Endpunkte prüft (Phase 5)
-4. **Test-Runner:** Script das alle Tests ausführt und strukturiert reportet (Phase 7)
-5. **Deploy-Script:** KI kann Build erstellen, testen, deployen, rollback (Phase 5)
-6. **Plugin-Richtlinien:** Klare Vorgaben damit KI neue Plugins erstellen kann (Phase 3)
-7. **Dokumentation:** Aktuelle Architektur-Doku, API-Doku, Plugin-Guide (Phase 0+3+5)
-
----
-
-## Nächste Schritte
-
-1. ✅ Nextcloud Backup erstellt (`/Backups/leocrm/leocrm-backup-20260722.bundle`)
-2. ✅ Plan gründlich überprüft und korrigiert (+45h)
-3. ⬜ Plan freigeben
-4. ⬜ Phase 0 starten
-5. ⬜ Planungsdokumente aktualisieren

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

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

-### 2.4 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:
-

-        
-        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

-            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

-        """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

-
-### 5.5 Plugin-Download-Endpoint (4 Std)
-
-**Neue Route: `POST /api/v1/plugins/install-marketplace`**
-

-- ✅ Built-in Plugins laufen ohne Marketplace
-- ✅ Tests bestanden
-
----
-
-## Phase 6: Manifest-Anpassung & Konsolidierung
-
-**Ziel:** Alle in Phase 4 und 5 definierten Manifest-Felder werden ins `PluginManifest` integriert, bestehende Manifeste aktualisiert, und das Manifest-System finalisiert.
-
-**Wichtig:** Diese Phase baut auf Phase 4 (Versioning) und Phase 5 (Marketplace) auf und muss als letztes durchgeführt werden.
-
-### 6.1 PluginManifest erweitern (4 Std)
-
-**Aktuelles Manifest (verifiziert 2026-07-26):**
-```python

-    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

-### 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 |
-
----
-
-## Erfolgskriterien
-
-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 ✅
-
-### Phase 8–10 — nicht begonnen
-- Sicherheitsreste, CI, Backup/Monitoring
-- Aufwand: 38–66h

-## 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**

+"""Fix tags.owner_id missing column and contacts_tsv_trigger column mismatch.
+
+Bug 1: tags.owner_id — Migration 0102 tried to add owner_id to tags but only
+if the table existed at that point. If the tags table was created later (by
+plugin migration), owner_id was never added. This migration ensures owner_id
+exists on the tags table.
+
+Bug 2: contacts_tsv_trigger — The unified_search plugin migration 0001 created
+a trigger function referencing NEW.first_name, NEW.last_name, NEW.email,
+NEW.phone, NEW.mobile, NEW.notes. After migration 0021 unified contacts,
+the columns are named firstname, surname, email_1, phone_1, phone_2,
+projectnote. The trigger must be recreated with correct column names.

+"""Trigger dispatcher — routes events to matching automation definitions.
+
+This module provides the **generic** bridge between the EventBus and the
+automation execution engine.  It replaces the previous hard-coded event
+handler stubs (``on_contact_created`` etc.) with a single wildcard
+subscriber that queries the database for matching
+``AutomationDefinition`` rows and dispatches them through the common
+``run_automation`` execution core.
+
+Two event categories are supported:
+
+1. **Domain events** (durable, via Outbox → Worker → EventBus)
+   - trigger_type = ``"event"``
+   - trigger_config = ``{"event_name": "contact.created"}``
+   - Any event published to the EventBus (either directly or via the
+     outbox processor) can trigger an automation.
+
+2. **UI events** (ephemeral, via WebSocket → EventBus only)
+   - trigger_type = ``"ui"``
+   - trigger_config = ``{"event_name": "ui.contact_selected"}``
+   - UI events are **never** written to the outbox.  They flow directly
+     from the frontend WebSocket handler through the EventBus to this
+     dispatcher.
+
+All four trigger types (event, ui, schedule, manual) converge on the
+same ``run_automation`` execution engine, ensuring consistent condition
+evaluation, action execution, and run logging.
