+
+## 2. Test Rules
+
+### TDD (Test-Driven Development)
+
+- **Red-Green-Refactor:** Write failing test first → implement minimum code to pass → refactor.
+- **Every new endpoint gets a test BEFORE implementation.**
+- **Every bug fix starts with a reproduction test.**
+
+### Coverage Targets
+
+| Layer | Coverage Target | Measured By |
+|-------|----------------|-------------|
+| Backend Core (app/core/) | 85% | pytest-cov |
+| Backend Models+Services | 85% | pytest-cov |
+| Backend Routes | 85% | pytest-cov |
+| Backend Plugins | 80% | pytest-cov |
+| Frontend Components | 75% | vitest coverage |
+| Frontend Plugin UI | 70% | vitest coverage |
+| E2E (critical paths) | 100% of defined specs | Playwright |
+

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

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

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

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

+### Test Environment
+
+- Test DB: Ephemeral PostgreSQL (pytest-postgresql or testcontainers).
+- Test Redis: Ephemeral or fakeredis.
+- External services (IMAP, SMTP, OnlyOffice): Mocked via `unittest.mock.AsyncMock`.
+- Test fixtures in `conftest.py` provide: test client, authenticated client (per role), seeded data.
+
+---
+
+## 8. Architecture Reference
+
+Full architecture details: `architecture.md`
+
+Full task graph with test specs: `task_graph.json`
+
+Key ADRs:
+- ADR-01: PostgreSQL 16 (not SQLite)
+- ADR-02: ARQ (not Celery)
+- ADR-03: Built-in plugins with manifest (not dynamic pip-install)
+- ADR-04: TanStack Query (not Redux)
+- ADR-05: Session-based auth (not JWT)
+- ADR-06: Soft-delete with `deleted_at` column
+
+---
+
+## Handoff
+
+- **AGENTS.md status:** COMPLETE
+- **task_graph.json status:** COMPLETE (14 tasks: 7 v1 + 7 v2, all with test_spec, 143 features covered, v1/v2 separated, v2.1.0)
+- **architecture.md status:** COMPLETE (73/73 v1 features referenced, v2 sections marked)
+- **Ready for v1 implementation:** YES (pending quality_reviewer review + plan_mode transition to implementation_allowed)
+- **v2 implementation:** After v1 deployment, separate phase

+# LeoCRM — Architecture Feasibility Review
+
+**Project:** leocrm
+**Reviewer:** Solution Architect (Agent Zero)
+**Date:** 2026-06-28
+**Documents reviewed:** architecture.md (1939 lines), task_graph.json (965 lines, v2.0.0, 13 tasks), AGENTS.md (570 lines), requirements.md (2142 lines, 143 features)
+
+---
+
+## VERDICT: FEASIBLE_WITH_RISKS
+
+The architecture is fundamentally sound — the tech stack is coherent, the multi-tenant design is well-structured, and the API design covers the frontend's needs. However, there are **3 CRITICAL issues** in the task graph that must be fixed before implementation can start, plus **5 MAJOR issues** that affect feasibility of individual tasks.
+
+| Severity | Count |
+|----------|-------|
+| CRITICAL | 3 |
+| MAJOR | 5 |
+| MINOR | 6 |
+
+---
+
+## 1. TASK ORDERING
+
+### Finding: Minor inconsistency between execution_plan and parallelization_notes
+
+The dependency graph is correct:
+- T01 → no dependencies (foundation) ✅
+- T02, T03 → depend on T01 only ✅
+- T07, T09, T10 → depend on T01 + T02 ✅
+- T04, T05, T06, T11 → depend on T01 + T03 ✅
+- T08a, T08b, T08c → depend on T07 + respective backend ✅
+
+No hidden dependencies detected. T02 (Company/Contact) and T03 (Plugin Framework) are genuinely independent after T01. T09 does not depend on T03 (workflow engine uses event bus from T01, not plugin framework). T07 does not depend on T03 (frontend works without plugins — sidebar shows hardcoded v1 items).
+
+**Issue:** The `execution_plan` phases don't match the `parallelization_notes`:
+- T09 is in Phase 3 (alone, `parallel: true`), T07 is in Phase 4 (`parallel: false`), T10 is in Phase 5 — but all three depend only on T01+T02 and could run simultaneously.
+- The `parallelization_notes` correctly states T09 can run parallel with T07, and T10 can run parallel with T07/T09 — but the `execution_plan` structure implies sequential phases.
+- **Recommendation:** Merge T09, T07, T10 into a single phase with `parallel: true`, or add explicit cross-phase parallelism annotations.
+
+**Risk level:** MINOR — the parallelization_notes clarify intent, but the execution_plan structure could mislead the orchestrator into sequential execution.
+
+---
+
+## 2. TASK SIZING
+
+### Finding: T07 is critically oversized — MAJOR
+
+T07 (Frontend Core SPA) has:
+- **38 requirement IDs** (highest of any task)
+- **32 acceptance criteria** (highest of any task)
+- **estimated_lines: 600** (wildly underestimated)
+
+Realistic line count breakdown:
+| Component | Estimated Lines |
+|-----------|----------------|
+| Vite setup + App.tsx + Providers + Router | ~150 |
+| API Client (axios, interceptors, error handling) | ~100 |
+| Layout Shell (Sidebar, TopBar, ContentArea) | ~200 |
+| Auth Pages (Login, Password-Reset Request+Confirm) | ~150 |
+| Companies Feature (List + TanStack Table + Detail + Tabs + Form) | ~350 |
+| Contacts Feature (List + Detail + Form) | ~300 |
+| Settings Feature (Tree + Profile + Role Editor + User Mgmt) | ~250 |
+| Audit Log Page | ~100 |
+| Dashboard (Stat Cards + Recent Activity) | ~100 |
+| Global Search Results Page | ~80 |
+| i18n Setup (de/en locale files) | ~200 |
+| Shared UI Component Library (12+ components) | ~500 |
+| Tailwind CSS + Design Tokens | ~50 |
+| **Total** | **~2530** |
+
+At ~2500 lines, T07 is 4× the estimated size and would overwhelm a single implementation block.
+
+**Recommendation:** Split T07 into:
+- **T07a: Frontend Foundation** — Vite setup, App.tsx, API Client, Layout Shell, Auth Pages, UI Component Library, i18n, Tailwind, Routing (~1200 lines, ~15 ACs)
+- **T07b: Frontend Feature Pages** — Companies, Contacts, Settings, Audit Log, Dashboard, Search (~1300 lines, ~17 ACs)
+- T07b depends on T07a
+
+### Finding: T09 is borderline — MAJOR
+
+T09 combines two independent subsystems:
+1. KI-Copilot (NL→API translation, LLM client, query/execute/history, RBAC enforcement) — ~350 lines
+2. Workflow Engine (CRUD definitions, instances, step history, code-engine, event triggers, approval timeout) — ~450 lines
+
+Total: ~800 lines, 22 ACs. The two subsystems share no code — only both depend on T01+T02.
+
+**Recommendation:** Consider splitting into T09a (KI-Copilot) and T09b (Workflow Engine). They can run in parallel. If kept as one task, increase estimated_lines to 800 and ensure the delegation message clearly separates the two modules.
+
+---
+
+## 3. TECH STACK FIT
+
+### Finding: Stack is coherent — no compatibility concerns
+
+| Component | Technology | Compatibility |
+|-----------|-----------|---------------|
+| Backend framework | FastAPI (async Python) | ✅ Native async, OpenAPI auto-gen |
+| ORM | SQLAlchemy 2.0 async + asyncpg | ✅ Standard for FastAPI |
+| Database | PostgreSQL 16 | ✅ MVCC, tsvector FTS, JSONB, UUID |
+| Cache/Queue | Redis 7 | ✅ Sessions, caching, ARQ queue |
+| Job queue | ARQ | ✅ Async-native, Redis-based, works with FastAPI |
+| Migrations | Alembic | ✅ Standard for SQLAlchemy |
+| Frontend framework | React 18 | ✅ Modern, concurrent features |
+| Build tool | Vite | ✅ Fast HMR, ES modules |
+| Server state | TanStack Query v5 | ✅ Works with React 18, Suspense |
+| Client state | Zustand | ✅ Lightweight, complementary to TanStack Query |
+| Forms | React Hook Form + Zod | ✅ Type-safe validation |
+| Styling | Tailwind CSS | ✅ Utility-first, design tokens |
+| Rich text | TipTap | ✅ React-compatible |
+| PDF viewer | PDF.js | ✅ Mozilla, React-compatible |
+| Document editing | OnlyOffice | ✅ External container, iframe integration |
+| Testing (backend) | pytest + httpx | ✅ Standard for FastAPI |
+| Testing (frontend) | Vitest + Testing Library | ✅ Standard for Vite/React |
+| E2E | Playwright | ✅ Cross-browser, reliable |
+
+**Minor:** Python version not explicitly stated in architecture.md tech stack section. AGENTS.md mentions Python 3.12+ in conventions. Should be in the stack table.
+
+**Risk level:** NONE — stack is well-established and all components are known-compatible.
+
+---
+
+## 4. PLUGIN ARCHITECTURE
+
+### Finding: Framework design is sufficient for v2 plugins — but with concerns
+
+T03's plugin framework provides:
+- Plugin Registry (DB-backed) ✅
+- Manifest Schema (Pydantic) with endpoints, migrations, UI, events, services, preferences, notification_types ✅
+- Lifecycle Hooks (install/activate/deactivate/uninstall) ✅
+- Plugin DB Migration Runner with tenant_id validator ✅
+- UI Registry (routes, menu_items, detail_tabs, settings_pages, dashboard_widgets) ✅
+- Event Bus Integration ✅
+- Service Container Injection (db, cache, event_bus, storage, notifications) ✅
+
+v2 plugin requirements vs. framework support:
+| Plugin | Needs | Framework Support |
+|--------|-------|-------------------|
+| DMS | routes, events, migrations, UI, storage | ✅ All provided |
+| Calendar | routes, events, migrations, UI, ARQ (reminders) | ✅ ARQ via container.jobs |
+| Mail | routes, events, migrations, UI, IMAP/SMTP | ⚠️ IMAP/SMTP NOT in container — plugin implements its own |
+| Tags | routes, migrations, UI | ✅ |
+| Permissions | routes, migrations, UI | ✅ |
+
+**MAJOR concern:** T04 (DMS Backend) and T11 (Tags + Permissions + Entity Links Backend) have **identical acceptance criteria** for these endpoints:
+- `GET /api/v1/dms/files/{id}/permissions`
+- `POST /api/v1/dms/files/{id}/link`
+- `DELETE /api/v1/dms/files/{id}/link`
+- `POST /api/v1/dms/files/{id}/share-link`
+- `GET /api/public/share/{token}` mit expired link → 410
+- `DMS plugin listens to company.deleted event → linked files cleanup`
+- `Folder permissions enforced: user without read → 403`
+
+Both tasks are scheduled in Phase 6 (parallel). Two implementers would write the same endpoints → merge conflict.
+
+Additionally, T04's test_spec runs `tests/test_tags.py` with `--cov=app/plugins/builtins/tags` — but Tags are T11's responsibility, not T04's.
+
+**Recommendation:** Clearly separate responsibilities:
+- T04: DMS folders, files, upload, preview, OnlyOffice, bulk operations, DMS search
+- T11: Tags CRUD + assignment, Permissions (file_shares, folder_permissions, share_links), Entity links (file_links)
+- Remove duplicated ACs from one task (keep in the task that owns the endpoint)
+- Remove `tests/test_tags.py` from T04's test_spec
+
+**Risk level:** MAJOR — parallel execution with overlapping ACs will cause implementation conflicts.
+
+---
+
+## 5. API DESIGN
+
+### Finding: Endpoints are sufficient for T07 — one minor gap
+
+T07 frontend needs vs. available endpoints:
+| Frontend Need | API Endpoint | Available In |
+|---------------|-------------|-------------|
+| Login/logout/me | `/api/v1/auth/*` | T01 ✅ |
+| Password reset | `/api/v1/auth/password-reset/*` | T01 ✅ |
+| Tenant switch | `/api/v1/auth/switch-tenant` | T01 ✅ |
+| User CRUD | `/api/v1/users` | T01 ✅ |
+| Role CRUD | `/api/v1/roles` | T01 ✅ |
+| User settings | `/api/v1/users/me/settings` | T01 ✅ |
+| Company CRUD + search + export | `/api/v1/companies` | T02 ✅ |
+| Contact CRUD + search + export | `/api/v1/contacts` | T02 ✅ |
+| Company-Contact N:M links | `/api/v1/companies/{id}/contacts/{cid}` | T02 ✅ |
+| Import/preview | `/api/v1/import`, `/api/v1/import/preview` | T02 ✅ |
+| Audit log | `/api/v1/audit-log` | T01 ✅ |
+| Notifications | `/api/v1/notifications` | T01 ✅ |
+| Global search | `/api/v1/search` | T01/T02 ✅ |
+| Health | `/api/v1/health` | T01 ✅ |
+| Dashboard stats | **MISSING** | ❌ |
+| Plugin menu items | `/api/v1/plugins` | T03 (not a dependency, but done earlier) ✅ |
+
+**MINOR gap:** T07's AC says "Dashboard renders with stat cards + recent activity" but there is no `GET /api/v1/dashboard` or `GET /api/v1/stats` endpoint. The frontend can compose this from existing endpoints (count companies, count contacts, recent audit log), but an aggregated endpoint would be cleaner.
+
+**Recommendation:** Either add a `GET /api/v1/dashboard` endpoint to T01 or T02, or document that the dashboard composes from `GET /api/v1/companies?page_size=1` (for total count) + `GET /api/v1/contacts?page_size=1` + `GET /api/v1/audit-log?page_size=10`.
+
+Also: T02 has AC `GET /api/v1/companies/{id}/emails → 200 (empty array wenn mail plugin inactive)` — this is a v2 endpoint stub in a v1 task. The implementer needs to know to return an empty array when the mail plugin is not active. This should be explicitly documented as a conditional stub.
+
+---
+
+## 6. DATABASE SCHEMA
+
+### Finding: MAJOR — users table has FK references to v2 tables that don't exist in v1
+
+The `users` table includes:
+```
+default_calendar_id | UUID | FK→calendars.id NULL
+default_mail_account_id | UUID | FK→mail_accounts.id NULL
+```
+
+`calendars` and `mail_accounts` are v2 plugin tables created by T05 and T06 respectively. In v1, these tables don't exist. The Alembic initial migration (T01) would fail trying to create FK constraints to non-existent tables.
+
+**Recommendation:**
+1. Remove `default_calendar_id` and `default_mail_account_id` from the initial v1 migration
+2. Add these columns in v2 plugin migrations (T05 adds `default_calendar_id`, T06 adds `default_mail_account_id`) with FK constraints
+3. Or: add the columns without FK constraints in v1, add FKs in v2 migrations
+
+### Other schema findings:
+
+- `plugin_migrations` table: described in text (line 1205) but not formally defined as a table with columns. MINOR — should be in the schema section.
+- `groups` table: referenced by `folder_permissions.group_id`, `file_shares.group_id`, `calendar_shares.group_id` but not defined anywhere. This is a v2 concern but should be documented. MINOR.
+- No `user_groups` or `groups` table in the schema — several v2 features reference group-based sharing. MAJOR for v2, but not blocking for v1.
+- All core tables have proper indexes, tenant_id, timestamps, and soft-delete where appropriate. ✅
+- FTS design with tsvector + GIN is correct. ✅
+- UUID PKs with `gen_random_uuid()` — correct for PostgreSQL 16. ✅
+
+---
+
+## 7. FRONTEND ARCHITECTURE
+
+### Finding: Detailed enough for T07 implementation — MINOR gaps
+
+The frontend architecture section covers:
+- Full stack table (React 18, Vite, React Router v6, TanStack Query, Zustand, RHF+Zod, Tailwind, etc.) ✅
+- Complete routing table with all routes ✅
+- State management strategy (TanStack Query / Zustand / URL state) ✅
+- i18n setup (de/en, locale files, date-fns) ✅
+- Accessibility (ARIA, 44px, reduced-motion, sr-only, keyboard, WCAG 2.1 AA) ✅
+- Design system based on approved prototype ✅
+- Frontend directory structure ✅
+
+Missing details (MINOR):
+- No API client design (interceptor pattern, error normalization, 401 redirect logic) — mentioned in T07 description but not in architecture.md
+- No data flow diagram (how TanStack Query hooks connect to API client → backend)
+- PluginRegistry.tsx / PluginLoader.tsx described conceptually but no implementation contract
+- No specific file-per-feature breakdown (e.g., what files go in `features/companies/`)
+
+These gaps are fillable from AGENTS.md conventions and the T07 task description. Not blocking.
+
+**Risk level:** LOW — architecture + AGENTS.md conventions provide sufficient guidance.
+
+---
+
+## 8. KI-COPILOT + WORKFLOW ENGINE
+
+### Finding: T09 is under-scoped on requirements but over-scoped on acceptance criteria — MAJOR
+
+T09 has only **5 requirement IDs** but **22 acceptance criteria**:
+- F-AI-01 → covers entire AI Copilot subsystem (query, execute, history, RBAC, audit, tenant isolation, field permissions) = 8 ACs
+- F-WF-01 → covers entire Workflow Engine (definition CRUD, instances, advance/approve/reject/cancel, event triggers, step history, code-engine, approval timeout) = 14 ACs
+- F-CORE-01 → event bus (shared with T01)
+- F-CORE-06 → API-first (architectural principle, not a feature)
+- F-TEST-01 → testing (shared across all tasks)
+
+The 5 reqs is misleading — F-AI-01 and F-WF-01 are each complex subsystems masquerading as single features. The 22 ACs are well-defined and testable, but implementing two independent subsystems in one delegation is risky.
+
+**The two subsystems share no code:**
+- KI-Copilot uses: ai_conversations model, LLM client, user session (T01), audit log (T01)
+- Workflow Engine uses: workflows/instances/step_history models, event bus (T01), ARQ (T01)
+- They don't reference each other
+
+**Recommendation:** Split T09 into:
+- **T09a: KI-Copilot API** — ai_conversations, LLM client, query/execute/history, RBAC enforcement (~350 lines, 8 ACs)
+- **T09b: Workflow Engine** — workflow CRUD, instances, code-engine, event triggers, approval timeout (~450 lines, 14 ACs)
+- Both depend on T01+T02, can run in parallel
+
+If kept as one task, increase estimated_lines from 700 to 800+ and ensure the delegation message explicitly separates the two modules with clear file boundaries.
+
+---
+
+## 9. DEPLOYMENT READINESS
+
+### Finding: Architecture supports Docker/Coolify deployment — MINOR gaps
+
+Present in architecture:
+- Docker Compose with all 6 services (backend, frontend, postgres, redis, worker, onlyoffice) ✅
+- Health checks for backend container ✅
+- Environment variables documented with .env.example plan ✅
+- Backup strategy (pg_dump daily + storage backup) ✅
+- Named volumes for persistent data ✅
+- Non-root container user (app:app) in AGENTS.md forbidden patterns ✅
+- Structured JSON logging for observability ✅
+- Prometheus metrics endpoint planned ✅
+
+Missing (MINOR):
+- No Dockerfiles (backend/frontend) — implementation concern (T01/T07), not architecture
+- No Coolify-specific configuration — Coolify can use docker-compose directly, but no coolify.json or resource limits documented
+- No SSL/TLS documentation — Coolify uses Traefik for LE certificates, but this isn't stated in architecture
+- No resource limits (CPU/memory) for containers — important for multi-tenant production
+- No logging driver configuration for Docker — structured logging is at app level, but Docker log rotation isn't mentioned
+- OnlyOffice container is always in docker-compose — should use Docker Compose profiles for optional services
+- No database initialization script (create DB, run initial migration) documented in deployment flow
+
+**Risk level:** LOW — all gaps are deployment-phase concerns, not architecture blockers. T10 covers documentation.
+
+---
+
+## 10. v1/v2 BOUNDARY
+
+### Finding: Boundary is mostly clean — one MAJOR schema issue, one MINOR stub issue
+
+### v1 can ship standalone: ✅ (with fix)
+
+| v1 Task | Standalone? | Notes |
+|---------|------------|-------|
+| T01 (Core+Auth) | ✅ | Plugin framework ready, no plugins installed |
+| T02 (Company+Contact) | ✅ | Full CRM without plugins |
+| T03 (Plugin Framework) | ✅ | Framework ready, zero plugins activated |
+| T07 (Frontend Core) | ✅ | Companies, contacts, settings, dashboard — no plugin UIs |
+| T09 (KI-Copilot+Workflows) | ✅ | AI + workflows work on core entities |
+| T10 (Monitoring+Docs) | ✅ | Health, metrics, docs for v1 scope |
+
+### Issues affecting v1 standalone:
+
+**MAJOR (blocking):** `users` table FK references to v2 tables (`calendars.id`, `mail_accounts.id`) — v1 migration fails. (See §6)
+
+**MINOR:** T02 has AC `GET /api/v1/companies/{id}/emails → 200 (empty array)` — this is a v2 mail endpoint stub. The v1 implementer must handle this gracefully (return empty array when mail plugin inactive). Should be documented as a conditional stub, not a full endpoint implementation.
+
+**MINOR:** T07 company detail shows "Files placeholder, Emails placeholder" tabs — clean v1/v2 boundary via placeholder tabs. ✅
+
+### v1/v2 separation in task graph:
+- v1 tasks: T01, T02, T03, T07, T09, T10 (6 tasks) ✅
+- v2 tasks: T04, T05, T06, T11, T08a, T08b, T08c (7 tasks) ✅
+- No v1 task depends on a v2 task ✅
+- No v2 task is required for v1 to function ✅
+- Feature coverage: 73 v1 features / 70 v2 features — all covered ✅
+
+---
+
+## CRITICAL ISSUES (must fix before implementation)
+
+### C1: T04/T11 acceptance criteria overlap
+
+**Problem:** T04 (DMS Backend) and T11 (Tags+Permissions+Links Backend) have 7 identical acceptance criteria for the same endpoints (permissions, file links, share-links, event cleanup, folder permissions). Both are in Phase 6 (parallel) → two implementers writing the same code.
+
+T04's test_spec also includes `tests/test_tags.py` and `--cov=app/plugins/builtins/tags` — Tags are T11's responsibility.
+
+**Fix:**
+- T04 owns: DMS folders, files, upload, preview, OnlyOffice, bulk ops, DMS search
+- T11 owns: Tags CRUD + assignment + bulk, Permissions (file_shares, folder_permissions, share_links), Entity links (file_links), public share endpoint
+- Remove duplicated ACs from T04
+- Remove `tests/test_tags.py` and tags coverage from T04's test_spec
+
+### C2: v2 tasks have non-compliant test_spec
+
+**Problem:** T08a, T08b, T08c, T11 have `test_spec` as plain strings instead of structured objects:
+```json
+"test_spec": "Component tests for file browser, upload, share dialog, tag picker."
+```
+Instead of the mandatory structure:
+```json
+"test_spec": {
+  "commands": [...],
+  "expected_results": "...",
+  "test_files": [...],
+  "coverage_target": 80
+}
+```
+
+**Fix:** Convert all 4 tasks' test_spec to structured objects with commands, test_files, expected_results, coverage_target.
+
+### C3: v2 tasks use invalid subagent profiles
+
+**Problem:**
+- T08a, T08b, T08c use `"subagent_profile": "frontend_dev"` — this profile does not exist
+- T11 uses `"subagent_profile": "backend_dev"` — this profile does not exist
+- Available profiles: `implementation_engineer`, `developer`, etc.
+
+**Fix:** Change all v2 tasks to `"subagent_profile": "implementation_engineer"` (matching v1 tasks and AGENTS.md).
+
+---
+
+## MAJOR ISSUES (should fix before implementation)
+
+### M1: T07 oversized (38 reqs, 32 ACs, ~2500 lines estimated vs 600 stated)
+Split into T07a (Frontend Foundation) + T07b (Frontend Feature Pages).
+
+### M2: users table FKs to v2 tables (calendars.id, mail_accounts.id)
+Remove from v1 migration, add in v2 plugin migrations.
+
+### M3: T09 combines two independent subsystems (KI-Copilot + Workflow Engine, 22 ACs)
+Split into T09a (KI-Copilot) + T09b (Workflow Engine), or increase estimated_lines and ensure clear module separation in delegation.
+
+### M4: T08a/T08c acceptance criteria are mixed
+T08a (DMS+Tags+Permissions) has a Mail AC ("shared mailbox selector"). T08c (Mail+Search) has a DMS AC ("DMS route /dms renders file browser") and a Docker Compose AC. Reassign ACs to correct tasks.
+
+### M5: T04 test_spec includes tags tests (T11's responsibility)
+Remove `tests/test_tags.py` and `--cov=app/plugins/builtins/tags` from T04's test_spec.
+
+---
+
+## MINOR ISSUES (nice to fix, non-blocking)
+
+### m1: Execution plan phases don't reflect parallelization notes
+T09/T07/T10 are in separate phases but could run parallel. Merge or annotate.
+
+### m2: No dashboard/stats endpoint for T07's dashboard stat cards
+Add `GET /api/v1/dashboard` or document client-side composition.
+
+### m3: plugin_migrations table not formally defined in schema section
+Add table definition with columns.
+
+### m4: No Coolify-specific deployment config or SSL/TLS documentation
+Document Traefik SSL termination and Coolify deployment flow.
+
+### m5: OnlyOffice container always in docker-compose
+Use Docker Compose profiles for optional services.
+
+### m6: Python version not in tech stack table
+Add Python 3.12+ to the stack table in architecture.md §1.
+
+---
+
+## TOP 3 RISKS
+
+1. **T07 oversized task** — 38 reqs / 32 ACs / ~2500 lines in one delegation. High probability of incomplete implementation, context window exhaustion, or quality degradation. Must split.
+
+2. **T04/T11 endpoint overlap** — 7 identical ACs across two parallel tasks. Will cause merge conflicts, duplicate code, and test failures when both implementers write the same endpoints.
+
+3. **users table FK to non-existent v2 tables** — v1 Alembic migration will fail on `FK→calendars.id` and `FK→mail_accounts.id` because those tables don't exist until v2 plugin installation.
+
+---
+
+## RECOMMENDATION FOR PHASE 3 START
+
+**Conditional GO — fix 3 CRITICAL issues first, then start implementation.**
+
+Required actions before implementation:
+1. Fix C1: Separate T04/T11 endpoint ownership, remove duplicate ACs
+2. Fix C2: Convert T08a/T08b/T08c/T11 test_spec to structured objects
+3. Fix C3: Change invalid subagent profiles to `implementation_engineer`
+4. Fix M1: Split T07 into T07a + T07b
+5. Fix M2: Remove v2 FKs from users table in v1 migration
+6. Fix M4: Reassign mixed ACs between T08a and T08c
+7. Fix M5: Remove tags tests from T04 test_spec
+
+Recommended (non-blocking):
+- Fix M3: Split T09 into T09a + T09b (reduces delegation risk)
+- Fix m1-m6 for documentation quality
+
+After fixes: task_graph.json v2.1.0, architecture.md v1.1, then proceed to implementation.

+
+### Patterns
+
+- **Monolith:** Single FastAPI app, alle Module fest eingebaut
+- **Dual-Interface:** HTML routes (Jinja2) + JSON API routes parallel
+- **Service-Layer:** Business-Logik in `services/`, Routes sind dünn
+- **SQLAlchemy 2.0:** DeclarativeBase, Mapped types, mapped_column
+- **Soft-Delete:** `deleted_at` auf Company, Contact, Folder, File
+- **N:M Junctions:** CompanyContact, TagAssignment, FileEntityLink, EntryLink, CalendarShare
+- **RBAC:** 3 Rollen (admin, editor, viewer) — hardcoded in `require_admin` dependency
+- **Demo-Seed:** init_db() erstellt admin/admin + 2 Firmen + 3 Kontakte
+

+
+## 2. Konflikte: Requirements vs Code-Realität
+
+### K1: Multi-Tenant (F-AUTH-07, F-CORE-02) — KRITISCH
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| tenant_id | Auf allen Core-Tabellen | **Nirgendwo vorhanden** |
+| Tenant-Isolation | ORM filtert automatisch | **Keine Filterung** |
+| User-Tenant-Zuordnung | User kann zu mehreren Tenants gehören | **Nicht implementiert** |
+| Tenant-Switch UI | Wechsel aktiver Tenant | **Nicht vorhanden** |
+| Plugin-Tabellen | Müssen tenant_id haben | **N/A (keine Plugins)** |
+
+**Evidence:**
+- `models.py` Zeile 42: `class User(Base):` docstring sagt explizit `"Login account for LeoCRM (single-tenant)."`
+- Keine `tenant_id`-Spalte auf Company, Contact, Folder, File, Tag, Calendar, CalendarEntry, Notification, Permission, ShareLink
+- `deps.py`: Session speichert nur `user_id`, kein `tenant_id`-Kontext
+- Keine Tenant-Modell-Klasse existiert
+
+**Impact:** Fundamentale Architektur-Veränderung erforderlich. Jede Tabelle braucht tenant_id, ORM-Queries müssen tenant-gefiltert sein, User-Tenant-Mapping-Tabelle nötig.
+
+---
+
+### K2: Plugin-System (F-PLUGIN-01, F-PLUGIN-02) — KRITISCH
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Plugin-Architektur | Core-Feature v1 | **Nicht existent** |
+| DMS/Kalender/Tags/Mail | Als Plugins implementiert | **Fest im Core eingebaut** |
+| Plugin-Manifest | Definiertes Format | **Nicht vorhanden** |
+| Lifecycle-Hooks | install/activate/deactivate/uninstall | **Nicht vorhanden** |
+| Plugin-API-Endpunkte | Plugins registrieren eigene Routes | **Nicht vorhanden** |
+| Plugin-DB-Migration | Eigene Migrationen | **Nicht vorhanden** |
+| Plugin-Abhängigkeiten | Deklarierbar | **Nicht vorhanden** |
+
+**Evidence:**
+- `grep -rn 'plugin\|Plugin\|manifest\|lifecycle\|activate\|deactivate' app/` → **0 Treffer**
+- DMS: `models.py` Folder/File/FileEntityLink + `dms_service.py` (26KB) + `dms_routes.py` — alles fest im Core
+- Kalender: `models.py` Calendar/CalendarShare/CalendarEntry/Attendee/EntryLink/SubTask + `calendar_service.py` (21KB) + `calendar_routes.py` — fest im Core
+- Tags: `models.py` Tag/TagAssignment + `tag_service.py` + `tag_routes.py` — fest im Core
+- Keine Plugin-Registry, kein Plugin-Loader, kein Manifest-Format
+
+**Impact:** Komplette Plugin-Architektur muss neu gebaut werden. Bestehende DMS/Kalender/Tag-Module müssen in Plugins umgewandelt werden.
+
+---
+
+### K3: Datenbank — SQLite vs PostgreSQL — KRITISCH
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| DB-Engine | PostgreSQL 16 | **SQLite** |
+| Connection-Pooling | PostgreSQL MVCC | **SQLite WAL, check_same_thread=False** |
+| Concurrent Writes | Multi-User fähig | **SQLite limitiert** |
+
+**Evidence:**
+- `config.py`: `db_path: str = Field(default=str(Path("/data/leocrm.db")))` → SQLite-Datei
+- `config.py`: `database_url` property → `f"sqlite:///{self.db_path}"` 
+- `session.py`: SQLite-spezifische PRAGMAs (`PRAGMA foreign_keys = ON`, `PRAGMA journal_mode = WAL`)
+- `session.py`: `connect_args={"check_same_thread": False}` — SQLite-only
+- `pyproject.toml`: Keine `psycopg2`/`asyncpg`/`psycopg`-Dependency
+
+**Impact:** DB-Layer muss auf PostgreSQL umgestellt werden. Session-Engine, PRAGMAs, connect_args müssen angepasst werden.
+
+---
+
+### K4: Frontend — Jinja2 vs React SPA — KRITISCH
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Frontend | React SPA (client-side) | **Jinja2 Templates (server-side)** |
+| i18n | DE + EN, Sprachwahl persistiert | **Nicht implementiert** |
+| UI-Plugin-Framework | Plugins registrieren UI-Komponenten | **Nicht vorhanden** |
+
+**Evidence:**
+- `app/templates/`: 7 Jinja2-HTML-Templates (login, register, dashboard, company_form, contact_form, contact_list, base)
+- `html_routes.py`: Jinja2Templates, TemplateResponse
+- Keine `package.json`, keine `.tsx`/`.jsx`-Dateien, kein React/Vite-Setup
+- `pyproject.toml`: `jinja2==3.1.5` als Dependency
+- Requirements Annahme 3: "SPA-Frontend: Client-side rendering mit React SPA (bestätigt durch genehmigten Prototyp leocrm-prototype-x7k2p9)"
+
+**Impact:** Komplettes Frontend muss als React SPA neu gebaut werden. Jinja2-Templates und HTML-Routes werden obsolet. UI-Plugin-Framework (F-CORE-04) muss in React integriert werden.
+
+---
+
+### K5: F-CORE-01 — Event Bus — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Event Bus | Core-Feature v1 | **Nicht implementiert** |
+| Events emit/subscribe | Typisiert, Payload, asynchron | **Nicht vorhanden** |
+| Plugin-Listener | Registrieren beim Aktivieren | **N/A** |
+
+**Evidence:** `grep -rn 'event.bus\|EventBus\|event_bus\|emit\|subscribe\|listener' app/` → **0 Treffer**
+
+---
+
+### K6: F-CORE-05 — Service Container / DI — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Service Container | Core-Services über Container | **Nicht implementiert** |
+| DI für Plugins | Services injiziert | **N/A** |
+| Mocking für Tests | Mock-Services injizierbar | **Nur DB-Session override** |
+
+**Evidence:** Services werden direkt importiert (`from app.services import company_service`), nicht über Container. FastAPI `Depends()` ist das einzige DI-Muster, aber nur für Request-Scoped dependencies (DB-Session, Current-User).
+
+---
+
+### K7: F-CORE-06 — API-First Architecture — TEILWEISE
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Alle Features über API | API-First | **Teilweise** — API routes existieren für alle Module |
+| UI ist API-Client | UI nutzt API | **❌ Jinja2 rendert server-side** |
+| API versioniert | z.B. /api/v1/ | **❌ Keine Versionierung** |
+| OpenAPI/Swagger | Auto-gen, dokumentiert | **⚠️ FastAPI auto-gen existiert, aber nicht explizit konfiguriert** |
+| Plugin-API-Endpunkte | Registrierbar | **N/A** |
+| KI-Copilot nutzt API | Gleiche Endpunkte | **Nicht implementiert** |
+
+**Evidence:**
+- API routes: `/api/companies`, `/api/contacts`, `/api/dms/*`, `/api/tags/*`, `/api/calendars`, `/api/entries`, `/api/notifications`, `/api/auth/*`
+- Kein `/api/v1/` Prefix — alle routes sind unversioniert
+- FastAPI generiert automatisch OpenAPI unter `/openapi.json`, aber nicht explizit konfiguriert oder dokumentiert
+- HTML routes existieren parallel (`/login`, `/` dashboard) — UI ist NICHT API-Client
+
+---
+
+### K8: F-CORE-07 — Async Job Queue — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Queue-System | Background-Jobs asynchron | **Nicht implementiert** |
+| Retry-Logic | Automatische Retries | **Nicht vorhanden** |
+| Dead-Letter-Queue | Bei wiederholtem Fehlschlag | **Nicht vorhanden** |
+| Job-Status UI | Sichtbar im UI | **Nicht vorhanden** |
+
+**Evidence:** `grep -rn 'celery\|Celery\|queue\|Queue\|async_job\|background_job\|job_queue' app/` → **0 Treffer**
+
+---
+
+### K9: F-CORE-08 — Caching-Strategie — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Cache-Backend | Sessions, Query-Cache, Plugin-Data | **Nicht implementiert** |
+| Cache-Invalidierung | Event-basiert | **N/A** |
+| TTL-Caching | Fallback | **Nur `@lru_cache` für Settings** |
+
+**Evidence:** `grep -rn 'cache\|Cache\|redis\|Redis' app/` → nur `functools.lru_cache` in `config.py` für Settings-Caching. Kein Redis, kein Query-Cache.
+
+---
+
+### K10: F-CORE-09 — User-Profile und Preferences — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| User-Profile | Profil mit Preferences | **Nicht implementiert** |
+| Sprache/Zeitzone/Theme | Umschaltbar | **Nicht vorhanden** |
+| Dashboard-Konfiguration | Konfigurierbar | **Nicht vorhanden** |
+| Plugin-Preferences | Eigene Felder registrierbar | **N/A** |
+
+**Evidence:** `User`-Modell hat nur: id, username, password_hash, role, personal_folder_id, default_calendar_id, created_at. Keine Preferences, keine Sprache, keine Zeitzone.
+
+---
+
+### K11: F-CORE-10 — Storage-Backend — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| S3-kompatibel | Konfigurierbar | **Nicht implementiert** |
+| Lokales Volume | Alternative | **Lokales Dateisystem** |
+| Presigned-URLs | Download ohne Plugin-Code | **Nicht vorhanden** |
+| Storage-Service | Core-Service für Plugins | **Direkter Dateizugriff** |
+
+**Evidence:**
+- `config.py`: `dms_storage_path: str = Field(default="/data/dms")` — lokales Verzeichnis
+- `dms_service.py`: Direkter Dateizugriff via `open()`, `Path`-Operationen
+- Keine S3/MinIO/boto3-Integration
+- `grep -rn 's3\|S3\|boto3\|storage_backend\|presigned' app/` → **0 Treffer**
+
+---
+
+### K12: F-CORE-11 — Generic Import/Export Service — TEILWEISE
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| CSV-Import | Mit Preview, Dry-Run, Fehler-Reporting | **⚠️ Nur direkter Import ohne Preview/Dry-Run** |
+| Excel-Export | Feld-Auswahl, Filterung | **⚠️ CSV + XLSX Export, aber begrenzte Feld-Auswahl** |
+| Plugin-Definitionen | Registrierbar | **N/A** |
+
+**Evidence:**
+- `import_service.py`: `import_companies_csv()`, `import_contacts_csv()` — direkter Import, kein Preview, kein Dry-Run
+- `export_service.py`: `export_companies_csv()`, `export_companies_xlsx()` — Export funktioniert, aber nicht generisch/plugin-fähig
+- Import/Export ist hardcoded für Companies/Contacts, nicht generisch
+
+---
+
+### K13: F-CORE-12 — PDF/Document Generation Service — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| PDF-Generierung | Aus Templates | **Nicht implementiert** |
+| Template-Engine | Variablen, Conditionals, Tabellen | **Nicht vorhanden** |
+| Storage-Integration | PDFs im Storage gespeichert | **N/A** |
+
+**Evidence:** `grep -rn 'pdf\|PDF\|weasyprint\|reportlab\|pdfkit' app/` → nur DMS-Preview (stream existing PDFs), keine Generierung
+
+---
+
+### K14: F-CORE-13 — Notification Service — TEILWEISE
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| In-App-Notifications | Bell-Icon, Badge-Zähler | **⚠️ DB-Modell existiert, keine UI** |
+| E-Mail-Channel | Notifications per Mail | **Nicht implementiert** |
+| Preferences | Pro User konfigurierbar | **Nicht vorhanden** |
+| Tenant-Isolation | Pro Tenant isoliert | **N/A (single-tenant)** |
+| Plugin-Notification-Typen | Registrierbar | **N/A** |
+
+**Evidence:**
+- `models.py`: `Notification`-Modell existiert (id, user_id, type, title, body, related_entry_id, is_read, created_at)
+- `notification_routes.py`: API für List/Mark-Read existiert
+- Keine E-Mail-Integration, keine Preferences, kein Badge-Zähler in UI (Jinja2-Templates haben kein Notification-UI)
+
+---
+
+### K15: F-AUTH-01 — Login mit E-Mail — KONFLIKT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Login-Feld | **E-Mail** + Passwort | **Username** + Passwort |
+| Session-Cookie | HttpOnly, Secure, SameSite=Strict | SameSite=**lax**, https_only conditional |
+
+**Evidence:**
+- `auth_service.py`: `authenticate_user(db, username, password)` — verwendet `username`, nicht `email`
+- `models.py`: `User.username: Mapped[str]` — kein `email`-Feld auf User
+- `deps.py`: Session speichert `user_id`, kein Tenant-Kontext
+- `main.py`: `same_site="lax"` (requirements sagen Strict), `https_only=settings.is_production` (requirements sagen Secure)
+
+---
+
+### K16: F-AUTH-03 — User-Verwaltung durch Admin — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Admin legt User an | E-Mail, Name, Rolle, Passwort | **Nicht implementiert** |
+| User-Tenant-Zuordnung | User wird Tenant zugeordnet | **N/A** |
+| Keine Self-Registration | Admin-only | **⚠️ Register-Template existiert** |
+
+**Evidence:**
+- Keine User-Management-Routes (kein `/api/users`, kein Admin-User-CRUD)
+- `app/templates/register.html` existiert — Self-Registration-Template (widerspricht Non-Goal #1)
+- `init_db.py`: Demo-Seed erstellt nur admin/admin
+
+---
+
+### K17: F-AUTH-05 — Passwort-Reset — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Reset-Flow | E-Mail mit Reset-Link | **Nicht implementiert** |
+| Reset-Link | Gültig 24h | **Nicht vorhanden** |
+
+**Evidence:** Keine Reset-Routes, keine Reset-Templates, keine Token-Generierung.
+
+---
+
+### K18: F-AUTH-07 — Multi-Tenant — FEHLT (siehe K1)
+
+Bereits in K1 abgedeckt. Keine Tenant-Modelle, keine User-Tenant-Mapping-Tabelle.
+
+---
+
+### K19: DMS/Calendar/Tags als Core vs Plugin — ARCHITEKTUR-KONFLIKT
+
+| Modul | Requirements | Code-Realität |
+|-------|-------------|---------------|
+| DMS | v2-Plugin (F-FILE/F-DMS/F-LINK/F-PERM) | **Core: 3 Modelle + 26KB Service + eigene Routes** |
+| Kalender | v2-Plugin (F-CAL-01..18) | **Core: 6 Modelle + 21KB Service + eigene Routes** |
+| Tags | v2-Plugin (F-TAG-01..04) | **Core: 2 Modelle + 8KB Service + eigene Routes** |
+| Mail | v2-Plugin (F-MAIL-01..19) | **Nicht implementiert** |
+
+**Evidence:** Alle Module sind direkt in `models.py`, `services/`, `routes/` integriert. Keine Plugin-Grenzen, keine Plugin-Schnittstellen.
+
+**Hinweis:** Requirements sagen Plugin-System ist v1-Core-Feature, aber die Module selbst sind v2-Plugins. Das bedeutet: In v1 muss das Plugin-System gebaut werden, aber DMS/Kalender/Tags können als v2-Plugins nachgezogen werden. Die bestehenden Implementierungen können als Referenz dienen, müssen aber auf Plugin-Architektur umgebaut werden.
+
+---
+
+## 3. Kompatibel — Was bereits passt

+## 4. F-CORE-Feature-Matrix
+
+| F-CORE-ID | Feature | Status im Code | Anmerkung |
+|-----------|--------|---------------|----------|
+| F-CORE-01 | Event Bus | ❌ Nicht implementiert | Keine Event-Infrastruktur |
+| F-CORE-02 | Tenant-Isolation | ❌ Nicht implementiert | Kein tenant_id, single-tenant |

+
+**Bilanz:** 0/13 vollständig implementiert, 3/13 teilweise, 10/13 fehlen komplett.
+
+---
+
+## 5. Empfehlung: Was vor Phase 2 angepasst werden muss
+
+### Priorität 1 — Fundamentale Architektur (vor allem anderen)
+
+1. **Datenbank-Migration: SQLite → PostgreSQL**
+   - `config.py`: `database_url` auf PostgreSQL umstellen
+   - `session.py`: SQLite-PRAGMAs entfernen, PostgreSQL-Engine konfigurieren
+   - `pyproject.toml`: `psycopg[binary]` oder `asyncpg` hinzufügen
+   - `docker-compose.yml`: PostgreSQL-Service hinzufügen
+
+2. **Multi-Tenant-Architektur**
+   - Neues `Tenant`-Modell + `UserTenant`-Mapping-Tabelle
+   - `tenant_id`-Spalte auf ALLE Core-Tabellen (Company, Contact, Folder, File, Tag, Calendar, etc.)
+   - ORM-Query-Filter: automatische tenant_id-Filterung (SQLAlchemy Event oder Query-Wrapper)
+   - Session-Kontext: aktiver tenant_id in Session speichern
+   - Tenant-Switch-Endpoint + UI
+
+3. **Frontend-Wechsel: Jinja2 → React SPA**
+   - React-Projekt-Setup (Vite + React + TypeScript)
+   - API-Client-Layer (fetch/axios gegen /api/* Endpunkte)
+   - Jinja2-Templates und html_routes.py werden obsolet
+   - i18n-Integration (DE + EN)
+   - UI-Plugin-Framework vorbereiten (F-CORE-04)
+
+### Priorität 2 — Core-Infrastructure (F-CORE)
+
+4. **Service Container / DI (F-CORE-05)**
+   - Zentralen Service-Container implementieren
+   - Core-Services registrieren: DB, Cache, Event Bus, Auth, Config, Logger
+   - Plugin-Schnittstelle für Service-Requests definieren
+
+5. **Event Bus (F-CORE-01)**
+   - Event-Publish/Subscribe-System implementieren
+   - Typisierte Events mit Payload
+   - Asynchrone Verarbeitung (ggf. via Job Queue)
+
+6. **Plugin-System (F-PLUGIN-01/02)**
+   - Plugin-Manifest-Format definieren
+   - Lifecycle-Hooks: install, activate, deactivate, uninstall
+   - Plugin-Registry + Loader
+   - Plugin-API-Endpunkt-Registrierung
+   - Plugin-DB-Migration (F-CORE-03)
+   - Plugin-Abhängigkeiten
+
+7. **API-Versionierung (F-CORE-06)**
+   - `/api/v1/` Prefix für alle API-Routes
+   - OpenAPI/Swagger explizit konfigurieren und dokumentieren
+   - HTML-Routes entfernen (UI wird React SPA = API-Client)
+
+### Priorität 3 — Weitere Core-Infrastructure
+
+8. **Async Job Queue (F-CORE-07)** — Queue-System für Background-Jobs
+9. **Caching (F-CORE-08)** — Redis-Anbindung, Query-Cache, Cache-Invalidierung
+10. **Storage-Backend (F-CORE-10)** — S3-kompatibler Storage-Service
+11. **User-Profile/Preferences (F-CORE-09)** — Profil-Erweiterung, Preferences
+12. **Notification Service (F-CORE-13)** — E-Mail-Channel, Preferences, Badge-UI
+13. **PDF Generation (F-CORE-12)** — Template-Engine, PDF-Generierung
+14. **Generic Import/Export (F-CORE-11)** — Generischer Service, Preview, Dry-Run
+
+### Priorität 4 — Auth-Ergänzungen
+
+15. **Login auf E-Mail umstellen (F-AUTH-01)** — username → email
+16. **User-Verwaltung durch Admin (F-AUTH-03)** — Admin-CRUD für User, Tenant-Zuordnung
+17. **Passwort-Reset (F-AUTH-05)** — Reset-Flow mit E-Mail
+18. **Register-Template entfernen** — Self-Registration ist Non-Goal
+19. **Cookie-Security anpassen** — SameSite=Strict, Secure immer
+
+### Was beibehalten werden kann
+
+- **Backend-Services** (company_service, contact_service, etc.) — Business-Logik ist solide
+- **Pydantic-Schemas** — Können für API-Validierung weiterverwendet werden
+- **DB-Modelle** — Felder/Beziehungen sind korrekt, müssen nur tenant_id ergänzt werden
+- **Test-Suite** — pytest-Tests können erweitert werden
+- **DMS/Calendar/Tag-Implementierungen** — Als Referenz für spätere Plugin-Entwicklung behalten
+
+---
+
+## 6. Zusammenfassung
+
+| Kategorie | Anzahl | Status |
+|-----------|--------|--------|
+| Kritische Konflikte | 4 | Multi-Tenant, Plugin-System, DB, Frontend |
+| F-CORE fehlend | 10/13 | Event Bus, Tenant-Isolation, Plugin-Migration, UI-Plugin, Service Container, Job Queue, Caching, User-Profile, Storage, PDF |
+| F-CORE teilweise | 3/13 | API-First, Import/Export, Notification |
+| F-CORE vollständig | 0/13 | — |
+| Auth-Konflikte | 4 | Login (username vs email), User-Verwaltung, Passwort-Reset, Cookie-Security |
+| Kompatibel | 7+ | Session-Auth, RBAC, Company/Contact CRUD, Data-Features, Health, DMS/Calendar/Tags (als Referenz) |
+
+**Fazit:** Die bestehende Codebase ist eine funktionsfähige v0.1-Implementierung (Single-Tenant, SQLite, Jinja2), die den bereinigten v1-Requirements in 4 kritischen Bereichen nicht entspricht: Multi-Tenant, Plugin-System, PostgreSQL, React SPA. 10 von 13 F-CORE-Features fehlen komplett. Die bestehende Business-Logik (Services, Schemas, Modelle) ist jedoch solide und kann als Basis für den Umbau dienen. Der Aufwand für Phase 2 ist erheblich — es handelt sich um eine Architektur-Migration, nicht um inkrementelle Erweiterungen.

+
+### Patterns
+
+- **Monolith:** Single FastAPI app, alle Module fest eingebaut
+- **Dual-Interface:** HTML routes (Jinja2) + JSON API routes parallel
+- **Service-Layer:** Business-Logik in `services/`, Routes sind dünn
+- **SQLAlchemy 2.0:** DeclarativeBase, Mapped types, mapped_column
+- **Soft-Delete:** `deleted_at` auf Company, Contact, Folder, File
+- **N:M Junctions:** CompanyContact, TagAssignment, FileEntityLink, EntryLink, CalendarShare
+- **RBAC:** 3 Rollen (admin, editor, viewer) — hardcoded in `require_admin` dependency
+- **Demo-Seed:** init_db() erstellt admin/admin + 2 Firmen + 3 Kontakte
+
+---
+
+## 2. Konflikte: Requirements vs Code-Realität
+
+### K1: Multi-Tenant (F-AUTH-07, F-CORE-02) — KRITISCH
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| tenant_id | Auf allen Core-Tabellen | **Nirgendwo vorhanden** |
+| Tenant-Isolation | ORM filtert automatisch | **Keine Filterung** |
+| User-Tenant-Zuordnung | User kann zu mehreren Tenants gehören | **Nicht implementiert** |
+| Tenant-Switch UI | Wechsel aktiver Tenant | **Nicht vorhanden** |
+| Plugin-Tabellen | Müssen tenant_id haben | **N/A (keine Plugins)** |
+
+**Evidence:**
+- `models.py` Zeile 42: `class User(Base):` docstring sagt explizit `"Login account for LeoCRM (single-tenant)."`
+- Keine `tenant_id`-Spalte auf Company, Contact, Folder, File, Tag, Calendar, CalendarEntry, Notification, Permission, ShareLink
+- `deps.py`: Session speichert nur `user_id`, kein `tenant_id`-Kontext
+- Keine Tenant-Modell-Klasse existiert
+
+**Impact:** Fundamentale Architektur-Veränderung erforderlich. Jede Tabelle braucht tenant_id, ORM-Queries müssen tenant-gefiltert sein, User-Tenant-Mapping-Tabelle nötig.
+
+---
+
+### K2: Plugin-System (F-PLUGIN-01, F-PLUGIN-02) — KRITISCH
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Plugin-Architektur | Core-Feature v1 | **Nicht existent** |
+| DMS/Kalender/Tags/Mail | Als Plugins implementiert | **Fest im Core eingebaut** |
+| Plugin-Manifest | Definiertes Format | **Nicht vorhanden** |
+| Lifecycle-Hooks | install/activate/deactivate/uninstall | **Nicht vorhanden** |
+| Plugin-API-Endpunkte | Plugins registrieren eigene Routes | **Nicht vorhanden** |
+| Plugin-DB-Migration | Eigene Migrationen | **Nicht vorhanden** |
+| Plugin-Abhängigkeiten | Deklarierbar | **Nicht vorhanden** |
+
+**Evidence:**
+- `grep -rn 'plugin\|Plugin\|manifest\|lifecycle\|activate\|deactivate' app/` → **0 Treffer**
+- DMS: `models.py` Folder/File/FileEntityLink + `dms_service.py` (26KB) + `dms_routes.py` — alles fest im Core
+- Kalender: `models.py` Calendar/CalendarShare/CalendarEntry/Attendee/EntryLink/SubTask + `calendar_service.py` (21KB) + `calendar_routes.py` — fest im Core
+- Tags: `models.py` Tag/TagAssignment + `tag_service.py` + `tag_routes.py` — fest im Core
+- Keine Plugin-Registry, kein Plugin-Loader, kein Manifest-Format
+
+**Impact:** Komplette Plugin-Architektur muss neu gebaut werden. Bestehende DMS/Kalender/Tag-Module müssen in Plugins umgewandelt werden.
+
+---
+
+### K3: Datenbank — SQLite vs PostgreSQL — KRITISCH
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| DB-Engine | PostgreSQL 16 | **SQLite** |
+| Connection-Pooling | PostgreSQL MVCC | **SQLite WAL, check_same_thread=False** |
+| Concurrent Writes | Multi-User fähig | **SQLite limitiert** |
+
+**Evidence:**
+- `config.py`: `db_path: str = Field(default=str(Path("/data/leocrm.db")))` → SQLite-Datei
+- `config.py`: `database_url` property → `f"sqlite:///{self.db_path}"` 
+- `session.py`: SQLite-spezifische PRAGMAs (`PRAGMA foreign_keys = ON`, `PRAGMA journal_mode = WAL`)
+- `session.py`: `connect_args={"check_same_thread": False}` — SQLite-only
+- `pyproject.toml`: Keine `psycopg2`/`asyncpg`/`psycopg`-Dependency
+
+**Impact:** DB-Layer muss auf PostgreSQL umgestellt werden. Session-Engine, PRAGMAs, connect_args müssen angepasst werden.
+
+---
+
+### K4: Frontend — Jinja2 vs React SPA — KRITISCH
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Frontend | React SPA (client-side) | **Jinja2 Templates (server-side)** |
+| i18n | DE + EN, Sprachwahl persistiert | **Nicht implementiert** |
+| UI-Plugin-Framework | Plugins registrieren UI-Komponenten | **Nicht vorhanden** |
+
+**Evidence:**
+- `app/templates/`: 7 Jinja2-HTML-Templates (login, register, dashboard, company_form, contact_form, contact_list, base)
+- `html_routes.py`: Jinja2Templates, TemplateResponse
+- Keine `package.json`, keine `.tsx`/`.jsx`-Dateien, kein React/Vite-Setup
+- `pyproject.toml`: `jinja2==3.1.5` als Dependency
+- Requirements Annahme 3: "SPA-Frontend: Client-side rendering mit React SPA (bestätigt durch genehmigten Prototyp leocrm-prototype-x7k2p9)"
+
+**Impact:** Komplettes Frontend muss als React SPA neu gebaut werden. Jinja2-Templates und HTML-Routes werden obsolet. UI-Plugin-Framework (F-CORE-04) muss in React integriert werden.
+
+---
+
+### K5: F-CORE-01 — Event Bus — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Event Bus | Core-Feature v1 | **Nicht implementiert** |
+| Events emit/subscribe | Typisiert, Payload, asynchron | **Nicht vorhanden** |
+| Plugin-Listener | Registrieren beim Aktivieren | **N/A** |
+
+**Evidence:** `grep -rn 'event.bus\|EventBus\|event_bus\|emit\|subscribe\|listener' app/` → **0 Treffer**
+
+---
+
+### K6: F-CORE-05 — Service Container / DI — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Service Container | Core-Services über Container | **Nicht implementiert** |
+| DI für Plugins | Services injiziert | **N/A** |
+| Mocking für Tests | Mock-Services injizierbar | **Nur DB-Session override** |
+
+**Evidence:** Services werden direkt importiert (`from app.services import company_service`), nicht über Container. FastAPI `Depends()` ist das einzige DI-Muster, aber nur für Request-Scoped dependencies (DB-Session, Current-User).
+
+---
+
+### K7: F-CORE-06 — API-First Architecture — TEILWEISE
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Alle Features über API | API-First | **Teilweise** — API routes existieren für alle Module |
+| UI ist API-Client | UI nutzt API | **❌ Jinja2 rendert server-side** |
+| API versioniert | z.B. /api/v1/ | **❌ Keine Versionierung** |
+| OpenAPI/Swagger | Auto-gen, dokumentiert | **⚠️ FastAPI auto-gen existiert, aber nicht explizit konfiguriert** |
+| Plugin-API-Endpunkte | Registrierbar | **N/A** |
+| KI-Copilot nutzt API | Gleiche Endpunkte | **Nicht implementiert** |
+
+**Evidence:**
+- API routes: `/api/companies`, `/api/contacts`, `/api/dms/*`, `/api/tags/*`, `/api/calendars`, `/api/entries`, `/api/notifications`, `/api/auth/*`
+- Kein `/api/v1/` Prefix — alle routes sind unversioniert
+- FastAPI generiert automatisch OpenAPI unter `/openapi.json`, aber nicht explizit konfiguriert oder dokumentiert
+- HTML routes existieren parallel (`/login`, `/` dashboard) — UI ist NICHT API-Client
+
+---
+
+### K8: F-CORE-07 — Async Job Queue — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Queue-System | Background-Jobs asynchron | **Nicht implementiert** |
+| Retry-Logic | Automatische Retries | **Nicht vorhanden** |
+| Dead-Letter-Queue | Bei wiederholtem Fehlschlag | **Nicht vorhanden** |
+| Job-Status UI | Sichtbar im UI | **Nicht vorhanden** |
+
+**Evidence:** `grep -rn 'celery\|Celery\|queue\|Queue\|async_job\|background_job\|job_queue' app/` → **0 Treffer**
+
+---
+
+### K9: F-CORE-08 — Caching-Strategie — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Cache-Backend | Sessions, Query-Cache, Plugin-Data | **Nicht implementiert** |
+| Cache-Invalidierung | Event-basiert | **N/A** |
+| TTL-Caching | Fallback | **Nur `@lru_cache` für Settings** |
+
+**Evidence:** `grep -rn 'cache\|Cache\|redis\|Redis' app/` → nur `functools.lru_cache` in `config.py` für Settings-Caching. Kein Redis, kein Query-Cache.
+
+---
+
+### K10: F-CORE-09 — User-Profile und Preferences — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| User-Profile | Profil mit Preferences | **Nicht implementiert** |
+| Sprache/Zeitzone/Theme | Umschaltbar | **Nicht vorhanden** |
+| Dashboard-Konfiguration | Konfigurierbar | **Nicht vorhanden** |
+| Plugin-Preferences | Eigene Felder registrierbar | **N/A** |

+| Lokales Volume | Alternative | **Lokales Dateisystem** |
+| Presigned-URLs | Download ohne Plugin-Code | **Nicht vorhanden** |
+| Storage-Service | Core-Service für Plugins | **Direkter Dateizugriff** |
+
+**Evidence:**

+- `dms_service.py`: Direkter Dateizugriff via `open()`, `Path`-Operationen
+- Keine S3/MinIO/boto3-Integration
+- `grep -rn 's3\|S3\|boto3\|storage_backend\|presigned' app/` → **0 Treffer**
+
+---

+| Excel-Export | Feld-Auswahl, Filterung | **⚠️ CSV + XLSX Export, aber begrenzte Feld-Auswahl** |
+| Plugin-Definitionen | Registrierbar | **N/A** |
+
+**Evidence:**
+- `import_service.py`: `import_companies_csv()`, `import_contacts_csv()` — direkter Import, kein Preview, kein Dry-Run
+- `export_service.py`: `export_companies_csv()`, `export_companies_xlsx()` — Export funktioniert, aber nicht generisch/plugin-fähig
+- Import/Export ist hardcoded für Companies/Contacts, nicht generisch
+
+---

+
+**Evidence:**
+- `models.py`: `Notification`-Modell existiert (id, user_id, type, title, body, related_entry_id, is_read, created_at)
+- `notification_routes.py`: API für List/Mark-Read existiert
+- Keine E-Mail-Integration, keine Preferences, kein Badge-Zähler in UI (Jinja2-Templates haben kein Notification-UI)
+
+---
+
+### K15: F-AUTH-01 — Login mit E-Mail — KONFLIKT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Login-Feld | **E-Mail** + Passwort | **Username** + Passwort |
+| Session-Cookie | HttpOnly, Secure, SameSite=Strict | SameSite=**lax**, https_only conditional |
+
+**Evidence:**
+- `auth_service.py`: `authenticate_user(db, username, password)` — verwendet `username`, nicht `email`
+- `models.py`: `User.username: Mapped[str]` — kein `email`-Feld auf User
+- `deps.py`: Session speichert `user_id`, kein Tenant-Kontext
+- `main.py`: `same_site="lax"` (requirements sagen Strict), `https_only=settings.is_production` (requirements sagen Secure)
+
+---
+
+### K16: F-AUTH-03 — User-Verwaltung durch Admin — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Admin legt User an | E-Mail, Name, Rolle, Passwort | **Nicht implementiert** |
+| User-Tenant-Zuordnung | User wird Tenant zugeordnet | **N/A** |
+| Keine Self-Registration | Admin-only | **⚠️ Register-Template existiert** |
+
+**Evidence:**
+- Keine User-Management-Routes (kein `/api/users`, kein Admin-User-CRUD)
+- `app/templates/register.html` existiert — Self-Registration-Template (widerspricht Non-Goal #1)
+- `init_db.py`: Demo-Seed erstellt nur admin/admin
+
+---
+
+### K17: F-AUTH-05 — Passwort-Reset — FEHLT
+
+| Aspekt | Requirements | Code-Realität |
+|---------|-------------|---------------|
+| Reset-Flow | E-Mail mit Reset-Link | **Nicht implementiert** |
+| Reset-Link | Gültig 24h | **Nicht vorhanden** |
+
+**Evidence:** Keine Reset-Routes, keine Reset-Templates, keine Token-Generierung.
+
+---
+
+### K18: F-AUTH-07 — Multi-Tenant — FEHLT (siehe K1)
+
+Bereits in K1 abgedeckt. Keine Tenant-Modelle, keine User-Tenant-Mapping-Tabelle.
+
+---
+
+### K19: DMS/Calendar/Tags als Core vs Plugin — ARCHITEKTUR-KONFLIKT
+
+| Modul | Requirements | Code-Realität |
+|-------|-------------|---------------|
+| DMS | v2-Plugin (F-FILE/F-DMS/F-LINK/F-PERM) | **Core: 3 Modelle + 26KB Service + eigene Routes** |
+| Kalender | v2-Plugin (F-CAL-01..18) | **Core: 6 Modelle + 21KB Service + eigene Routes** |
+| Tags | v2-Plugin (F-TAG-01..04) | **Core: 2 Modelle + 8KB Service + eigene Routes** |
+| Mail | v2-Plugin (F-MAIL-01..19) | **Nicht implementiert** |
+
+**Evidence:** Alle Module sind direkt in `models.py`, `services/`, `routes/` integriert. Keine Plugin-Grenzen, keine Plugin-Schnittstellen.
+
+**Hinweis:** Requirements sagen Plugin-System ist v1-Core-Feature, aber die Module selbst sind v2-Plugins. Das bedeutet: In v1 muss das Plugin-System gebaut werden, aber DMS/Kalender/Tags können als v2-Plugins nachgezogen werden. Die bestehenden Implementierungen können als Referenz dienen, müssen aber auf Plugin-Architektur umgebaut werden.
+
+---
+

+
+**Bilanz:** 0/13 vollständig implementiert, 3/13 teilweise, 10/13 fehlen komplett.
+
+---
+
+## 5. Empfehlung: Was vor Phase 2 angepasst werden muss
+
+### Priorität 1 — Fundamentale Architektur (vor allem anderen)
+
+1. **Datenbank-Migration: SQLite → PostgreSQL**
+   - `config.py`: `database_url` auf PostgreSQL umstellen
+   - `session.py`: SQLite-PRAGMAs entfernen, PostgreSQL-Engine konfigurieren
+   - `pyproject.toml`: `psycopg[binary]` oder `asyncpg` hinzufügen
+   - `docker-compose.yml`: PostgreSQL-Service hinzufügen
+
+2. **Multi-Tenant-Architektur**
+   - Neues `Tenant`-Modell + `UserTenant`-Mapping-Tabelle
+   - `tenant_id`-Spalte auf ALLE Core-Tabellen (Company, Contact, Folder, File, Tag, Calendar, etc.)
+   - ORM-Query-Filter: automatische tenant_id-Filterung (SQLAlchemy Event oder Query-Wrapper)
+   - Session-Kontext: aktiver tenant_id in Session speichern
+   - Tenant-Switch-Endpoint + UI
+
+3. **Frontend-Wechsel: Jinja2 → React SPA**
+   - React-Projekt-Setup (Vite + React + TypeScript)
+   - API-Client-Layer (fetch/axios gegen /api/* Endpunkte)
+   - Jinja2-Templates und html_routes.py werden obsolet
+   - i18n-Integration (DE + EN)
+   - UI-Plugin-Framework vorbereiten (F-CORE-04)
+
+### Priorität 2 — Core-Infrastructure (F-CORE)
+
+4. **Service Container / DI (F-CORE-05)**
+   - Zentralen Service-Container implementieren
+   - Core-Services registrieren: DB, Cache, Event Bus, Auth, Config, Logger
+   - Plugin-Schnittstelle für Service-Requests definieren
+
+5. **Event Bus (F-CORE-01)**
+   - Event-Publish/Subscribe-System implementieren
+   - Typisierte Events mit Payload
+   - Asynchrone Verarbeitung (ggf. via Job Queue)
+
+6. **Plugin-System (F-PLUGIN-01/02)**
+   - Plugin-Manifest-Format definieren
+   - Lifecycle-Hooks: install, activate, deactivate, uninstall
+   - Plugin-Registry + Loader
+   - Plugin-API-Endpunkt-Registrierung
+   - Plugin-DB-Migration (F-CORE-03)
+   - Plugin-Abhängigkeiten
+
+7. **API-Versionierung (F-CORE-06)**
+   - `/api/v1/` Prefix für alle API-Routes
+   - OpenAPI/Swagger explizit konfigurieren und dokumentieren
+   - HTML-Routes entfernen (UI wird React SPA = API-Client)
+
+### Priorität 3 — Weitere Core-Infrastructure
+
+8. **Async Job Queue (F-CORE-07)** — Queue-System für Background-Jobs
+9. **Caching (F-CORE-08)** — Redis-Anbindung, Query-Cache, Cache-Invalidierung
+10. **Storage-Backend (F-CORE-10)** — S3-kompatibler Storage-Service
+11. **User-Profile/Preferences (F-CORE-09)** — Profil-Erweiterung, Preferences
+12. **Notification Service (F-CORE-13)** — E-Mail-Channel, Preferences, Badge-UI
+13. **PDF Generation (F-CORE-12)** — Template-Engine, PDF-Generierung
+14. **Generic Import/Export (F-CORE-11)** — Generischer Service, Preview, Dry-Run
+
+### Priorität 4 — Auth-Ergänzungen
+
+15. **Login auf E-Mail umstellen (F-AUTH-01)** — username → email
+16. **User-Verwaltung durch Admin (F-AUTH-03)** — Admin-CRUD für User, Tenant-Zuordnung
+17. **Passwort-Reset (F-AUTH-05)** — Reset-Flow mit E-Mail
+18. **Register-Template entfernen** — Self-Registration ist Non-Goal
+19. **Cookie-Security anpassen** — SameSite=Strict, Secure immer
+
+### Was beibehalten werden kann
+
+- **Backend-Services** (company_service, contact_service, etc.) — Business-Logik ist solide
+- **Pydantic-Schemas** — Können für API-Validierung weiterverwendet werden
+- **DB-Modelle** — Felder/Beziehungen sind korrekt, müssen nur tenant_id ergänzt werden
+- **Test-Suite** — pytest-Tests können erweitert werden
+- **DMS/Calendar/Tag-Implementierungen** — Als Referenz für spätere Plugin-Entwicklung behalten
+
+---
+
+## 6. Zusammenfassung
+
+| Kategorie | Anzahl | Status |
+|-----------|--------|--------|
+| Kritische Konflikte | 4 | Multi-Tenant, Plugin-System, DB, Frontend |
+| F-CORE fehlend | 10/13 | Event Bus, Tenant-Isolation, Plugin-Migration, UI-Plugin, Service Container, Job Queue, Caching, User-Profile, Storage, PDF |
+| F-CORE teilweise | 3/13 | API-First, Import/Export, Notification |
+| F-CORE vollständig | 0/13 | — |
+| Auth-Konflikte | 4 | Login (username vs email), User-Verwaltung, Passwort-Reset, Cookie-Security |
+| Kompatibel | 7+ | Session-Auth, RBAC, Company/Contact CRUD, Data-Features, Health, DMS/Calendar/Tags (als Referenz) |
+
+**Fazit:** Die bestehende Codebase ist eine funktionsfähige v0.1-Implementierung (Single-Tenant, SQLite, Jinja2), die den bereinigten v1-Requirements in 4 kritischen Bereichen nicht entspricht: Multi-Tenant, Plugin-System, PostgreSQL, React SPA. 10 von 13 F-CORE-Features fehlen komplett. Die bestehende Business-Logik (Services, Schemas, Modelle) ist jedoch solide und kann als Basis für den Umbau dienen. Der Aufwand für Phase 2 ist erheblich — es handelt sich um eine Architektur-Migration, nicht um inkrementelle Erweiterungen.

+# Requirements Review: requirements.md
+
+**Datum:** 2026-06-28  
+**Reviewer:** Requirements Analyst (automatisiert)  
+**Datei:** `/a0/usr/workdir/dev-projects/leocrm/requirements.md`  
+**Zeilen:** 2131  
+**Feature-IDs:** ~141 aktive + 16 archivierte = ~157 total  
+**Status der Datei:** Finalisiert — ready_for_ui (laut Header)
+
+---
+
+## Section 1: Konsistenz-Issues
+
+### 1.1 Plugin-System vs. Core-Feature Widerspruch (CRITICAL)
+
+**Der zentrale Widerspruch der Datei.**
+
+**F-PLUGIN-01 (Zeile 848-851)** deklariert:
+> „Die Module sollen als Plugins realisiert sein, sodass das CRM später durch Plugins erweitert werden kann. Module (Mail, Kalender, Dateien, Tags) sind Plugins."
+
+**F-PLUGIN-02 (Zeile 857-860)** definiert Plugin-Schnittstelle, Lifecycle-Hooks, Plugin-Manifest.
+
+**Gleichzeitig** werden genau diese Module als detaillierte Core-Features mit konkreten HTTP-Endpunkten, DB-Schemas und Test-Szenarien spezifiziert:
+- **F-DMS-01 bis F-DMS-07 (Zeilen 991-1083):** DMS mit `POST /api/dms/folders`, `PATCH /api/dms/files/{id}`, etc.
+- **F-CAL-01 bis F-CAL-18 (Zeilen 1397-1662):** Kalender mit `POST /api/calendar/entries`, `GET /api/calendar/kanban`, etc.
+- **F-MAIL-01 bis F-MAIL-19 (Zeilen 1668-1951):** Mail mit `POST /api/mail/send`, IMAP IDLE, SMTP, PGP, etc.
+- **F-TAG-01 bis F-TAG-04 (Zeilen 1173-1223):** Tags mit `POST /api/tags/assign`, etc.
+
+**Widerspruch:** Wenn Module Plugins sind, dann gehören ihre detaillierten Feature-Spezifikationen (Endpunkte, DB-Schemas, Test-Szenarien) NICHT in die Core-Requirements. Der Core definiert die Plugin-Schnittstelle; das Plugin definiert seine eigenen Features. So wie es jetzt ist, wird das Plugin-System deklariert, aber dann werden die „Plugin-Module" im Core-Requirements-Dokument detailliert spezifiziert — als wären sie Core-Features.
+
+**F-CORE-01 bis F-CORE-13 (Zeilen 864-953)** definieren Core-Infrastruktur (Event Bus, Tenant-Isolation, Plugin-Migration, Service Container, API-First, Async Queue, Caching, Storage, Import/Export, PDF-Gen, Notification Service). Diese sind allesamt Architekturentscheidungen, keine Requirements.
+
+**Fazit:** Die Datei versucht gleichzeitig zu sagen „ diese Module sind Plugins" UND „ diese Module sind Core-Features mit konkreten Implementierungsdetails". Das ist ein architektonischer Widerspruch, der in der Architektur-Phase aufgelöst werden muss — nicht in den Requirements.
+
+### 1.2 Multi-Tenant (F-AUTH-07) vs. ältere Requirements ohne Tenant-Kontext (WARNING)
+
+**F-AUTH-07 (Zeile 135-138)** deklariert Multi-Tenant als v1-Feature:
+> „Das System ist Multi-Tenant-fähig. Mehrere Firmen (Tenants) können im System verwaltet werden. Daten sind pro Tenant isoliert."
+
+**F-CORE-02 (Zeile 871-874)** spezifiziert `tenant_id` auf allen Tabellen, ORM-Middleware für automatisches Query-Scoping.
+
+**Annahme 1 (Zeile 1978):** „v1 ist Multi-Tenant (Multi-Company) — mehrere Firmen (Tenants) im System."
+
+**Aber:** Die früher geschriebenen Requirements (F-AUTH-01 bis F-CONT-07, Zeilen 57-410) erwähnen Tenant-Kontext an keiner Stelle:
+- F-AUTH-01 (Login): kein Tenant-Bezug
+- F-AUTH-03 (User-Verwaltung): kein Tenant-Bezug — aber in Multi-Tenant muss ein User einem Tenant zugeordnet sein
+- F-COMP-01 (Firma anlegen): kein `tenant_id` in Feld-Tabelle (Zeile 156-186)
+- F-CONT-01 (Kontakt anlegen): kein `tenant_id` in Feld-Tabelle (Zeile 300-333)
+- F-COMP-05 (Pagination): kein Tenant-Filter erwähnt
+- F-COMP-06 (Suche): kein Tenant-Scoping erwähnt
+
+**Fazit:** Multi-Tenant wurde später hinzugefügt und die frühen Requirements wurden nicht nachträglich aktualisiert. Das führt zu einer Lücke: Wie verhält sich F-COMP-01 (Firma anlegen) in Multi-Tenant-Kontext? Wird die Firma automatisch dem aktiven Tenant zugeordnet? Kann ein User Firmen in mehreren Tenants anlegen? Diese Fragen sind in den Requirements nicht beantwortet.
+
+### 1.3 KI-Copilot (F-AI-01) mit voller API-Kontrolle vs. ältere UI-only-Flow-Requirements (WARNING)
+
+**F-AI-01 (Zeile 798-806)** deklariert:
+> „Der Copilot hat Zugriff auf die volle API und soll alles steuern können — Daten abfragen, erstellen, bearbeiten, löschen, Aktionen auslösen, Workflows triggern."
+
+**F-CORE-06 (Zeile 899-902)** deklariert API-First:
+> „Alle Core-Features und Plugin-Features sind primär über die API nutzbar. Die UI ist ein API-Client."
+
+**Aber:** Mehrere Requirements beschreiben nur UI-Flows ohne API-Bezug:
+- F-UI-01 (Responsive Design, Zeile 495-503): nur CSS-Breakpoints, kein API-Bezug
+- F-UI-02 (i18n, Zeile 509-517): nur Frontend-Library, kein API-Bezug
+- F-UI-03 (Toast-Notifications, Zeile 523-531): nur Frontend-Komponente
+- F-UI-04 (Loading-States, Zeile 537-545): nur Frontend-State
+- F-UI-05 (Empty-States, Zeile 551-559): nur Frontend-Komponente
+- F-UI-06 (Confirmation-Dialogs, Zeile 565-573): nur Frontend-Modal
+- F-UI-08 (Datenansichten, Zeile 579-582): nur Frontend-Toggle
+
+**Einschränkung:** Diese UI-Requirements sind legitimerweise UI-only — sie beschreiben Präsentationslogik, keine Datenoperationen. F-CORE-06 sollte explizit ausschließen, dass reine UI-Präsentations-Features keine API-Entpunkte benötigen. Aktuell ist die Formulierung „alle Features über API nutzbar" zu breit und suggeriert, dass auch Toast-Notifications einen API-Endpunkt haben müssten.
+
+**Zusätzlicher Befund:** F-AI-01 und F-CORE-06 wurden retroaktiv hinzugefügt. Die ursprünglichen Requirements (v0.1, archiviert in Appendix A, Zeile 2089-2128) beschreiben Jinja2-Templates und SQLite — eine völlig andere Architektur. Die Datei hat also mindestens drei Evolutionsschichten:
+1. v0.1: Single-Tenant, Jinja2, SQLite (archiviert)
+2. v0.3: React SPA, PostgreSQL, RBAC (Hauptteil)
+3. v0.5+: Multi-Tenant, Plugin-System, API-First, KI-Copilot, Mail/Kalender/DMS (hinzugefügt)
+
+Die Schichten wurden nicht vollständig integriert — Rückbezüge fehlen.
+
+### 1.4 Auth-Mechanismus-Unschärfe (WARNING)
+
+**F-AUTH-01 (Zeile 58):** „Session-basierte Auth mit HttpOnly+Secure+SameSite=Strict Cookie"
+
+**F-AUTH-02 (Zeile 72-78):** Test-Szenario sagt „Token wird entfernt" und Akzeptanzkriterium sagt „Server-Token-Blacklist optional für v1" — das suggeriert Token-basierte Auth (JWT?), nicht Session-basierte Auth.
+
+**F-INT-02 (Zeile 714-722):** „API-Endpunkte sind via Session-Cookie authentifiziert" aber erwähnt auch „Optional: API-Key für externe Integrationen".
+
+**F-SEC-03 (Zeile 616-624):** „Session läuft nach 8h ab" — aber „Token gültig <8h" und „Token nach 8h → API gibt 401" — wieder Token-Sprache.
+
+**Fazit:** Die Datei wechselt inkonsistent zwischen „Session" und „Token". Entweder es ist Session-basiert (Cookie + Server-Side Session Store) oder Token-basiert (JWT Stateless). Das muss entschieden und einheitlich formuliert werden.
+

+
+## Section 2: Requirements vs. Bauanleitung Assessment
+
+### 2.1 Enthaltene Implementierungsdetails
+
+Die Datei enthält massiv Implementierungsdetails, die in eine Requirements-Spec nicht gehören:
+
+#### HTTP-Endpunkte (Architektur, nicht Requirement)
+Jedes einzelne Akzeptanzkriterium spezifiziert konkrete HTTP-Endpunkte mit Pfaden, HTTP-Methoden, Query-Parametern und Response-Codes:
+- `POST /api/auth/login` (Zeile 65)
+- `GET /api/companies/{id}` (Zeile 207)
+- `DELETE /api/companies/{id}?cascade=true|false` (Zeile 235)
+- `GET /api/contacts?page=1&page_size=25&sort_by=last_name&sort_order=asc` (Zeile 396)
+- `POST /api/dms/files/upload` (Zeile 1013)
+- `GET /api/dms/files/{id}/preview` (Zeile 1041)
+- `POST /api/calendar/entries` (Zeile 1439)
+- `GET /api/calendar/kanban?period=this_week` (Zeile 1419)
+- `POST /api/mail/send` (Zeile 1693)
+- `GET /api/mail/search?q=angebot&folder=inbox` (Zeile 1709)
+- ...und dutzende weitere
+
+**Problem:** Der Endpunkt-Pfad ist eine Architekturentscheidung. Ein Requirement sagt „User kann sich einloggen" — der Pfad `/api/auth/login` ist Implementierung.
+
+#### DB-Schema-Definitionen (Architektur, nicht Requirement)
+- **F-COMP-01 (Zeilen 156-186):** Vollständige Feld-Tabelle mit Typen: `String(100)`, `Integer`, `Decimal`, `Picklist`, `FK→Company`, `Text(32000)`, etc. — das ist ein DB-Schema
+- **F-CONT-01 (Zeilen 300-333):** Vollständige Feld-Tabelle für Kontakte mit Typen
+- **F-COMP-07 (Zeile 277):** `audit_log` Tabellenname
+- **F-COMP-08 (Zeile 291):** `deletion_log` Tabellenname
+- **F-CONT-07 (Zeile 424):** `company_contacts` N:M-Tabellenname
+- **F-CORE-02 (Zeile 872):** `tenant_id` Feld auf allen Tabellen
+- **F-MAIL-03 (Zeile 1709):** `tsvector`-Index, `mail_body_tsv`, `mail_subject_tsv`
+- **F-CAL-12 (Zeile 1572):** `user_calendar_visibility` Tabellenname
+- **F-CAL-15 (Zeile 1614):** `assigned_to: user_id` Feldname
+
+**Problem:** Feldnamen, -typen und Tabellennamen sind Implementierungsdetails, die in das DB-Schema der Architektur gehören.
+
+#### Technologie-Entscheidungen (Architektur, nicht Requirement)
+- **F-CORE-07 (Zeile 907):** „Celery + Redis oder RQ + Redis" — Technologie-Wahl
+- **F-CORE-08 (Zeile 914):** „Redis als Cache-Backend" — Technologie-Wahl
+- **F-CORE-10 (Zeile 928):** „S3-kompatibles Storage (z.B. MinIO)" — Technologie-Wahl
+- **F-MAIL-02 (Zeile 1693):** „DOMPurify" — Library-Wahl
+- **F-MAIL-12 (Zeile 1846):** „python-gnupg" — Library-Wahl
+- **F-UI-02 (Zeile 517):** „react-i18next" — Library-Wahl
+- **F-DMS-04 (Zeile 1034):** „PDF.js" — Library-Wahl
+- **F-DATA-03 (Zeile 459):** „Pydantic-Schemas" — Library-Wahl
+- **F-INFRA-03 (Zeile 666):** „Python logging mit JSON-Formatter" — Library-Wahl

+#### Protokoll-Details (Architektur, nicht Requirement)
+- **F-MAIL-01 (Zeile 1670):** „IMAP4rev1 (RFC 3501)", „IMAP IDLE (RFC 2177)"
+- **F-MAIL-02 (Zeile 1693):** „multipart/mixed", „SMTP-Versand"
+- **F-MAIL-05 (Zeile 1733):** „References- und In-Reply-To-Header (RFC 5322)"
+- **F-MAIL-18 (Zeile 1929):** „AES-256, Key via Env-Var"
+- **F-CAL-08 (Zeile 1516):** „RRULE (RFC 5545)"
+- **F-CAL-09 (Zeile 1530):** „RFC 5545 konform"
+- **F-MAIL-18 (Zeile 1929):** „IMAP MOVE (RFC 6851)"
+
+#### Frontend-Komponenten-Namen (Architektur, nicht Requirement)
+- **F-CAL-01 (Zeile 1405):** `CalendarView` Komponente
+- **F-CAL-02 (Zeile 1419):** `KanbanCalendar` Komponente

+- **F-FILEUI-04 (Zeile 1363):** Multi-Select-State in `FileBrowser`
+- **F-MAIL-05 (Zeile 1741):** `ThreadView` Komponente
+

+- **F-CAL-06 (Zeile 1485):** `{appointment+normal: "#3B82F6", task+normal: "#F59E0B", *+follow_up: "#F97316", *+private: "#9CA3AF"}` — konkrete Hex-Codes
+- **F-COMP-04 (Zeile 235):** `deleted_at = NOW` — SQL-Ausdruck
+- **F-FILEUI-02 (Zeile 1335):** „Materialized Path oder rekursive Abfrage" — DB-Pattern
+- **F-FILEUI-06 (Zeile 1391):** „HTML5 Drag & Drop API" — Browser-API
+- **F-FILEUI-05 (Zeile 1377):** „XMLHttpRequest (für Progress-Events) oder WebSocket" — Technologie
+
+#### Algorithmus- und Logik-Details (Architektur, nicht Requirement)
+- **F-MAIL-07 (Zeilen 1762-1771):** Regelauswertungs-Reihenfolge, Background-Worker-Trigger
+- **F-MAIL-08 (Zeile 1786):** `vacation_sent_log`, No-Reply-Erkennung: „noreply", „no-reply", „donotreply"
+- **F-CAL-08 (Zeile 1516):** Recurrence-Instanz-Generierung, Exception-Handling

+
+## Section 3: Empfehlung
+
+### 3.1 Was in requirements.md bleiben sollte
+
+**Genuine Requirements — das WAS:**
+
+1. **Projektbeschreibung** (Zeilen 10-14) — Was ist das Projekt?
+2. **Domain Knowledge** (Zeilen 17-31) — Fachliche Begriffe und Referenzen
+3. **Tech-Stack-Entscheidungen** (Zeilen 34-52) — Hohe-Level-Entscheidungen (Backend, DB, Frontend, Deployment)
+4. **Feature-Anforderungstexte** — Die „Anforderung:"-Absätze jedes Features, bereinigt um Implementierungsdetails:

+10. **Open Questions** (Zeilen 2077-2085) — Bleibt
+
+### 3.2 Was nach architecture.md verschoben werden sollte
+
+**Architektur/Implementierung — das HOW:**
+
+1. **F-CORE-01 bis F-CORE-13 (Zeilen 864-953):** Komplett in architecture.md
+   - Event Bus, Tenant-Isolation (`tenant_id`), Plugin-Migration, UI-Plugin-Framework, Service Container/DI, API-First (Endpunkt-Versionierung `/api/v1/`), Async Job Queue (Celery/Redis), Caching (Redis), Storage-Backend (S3/MinIO), Import/Export Service, PDF-Gen, Notification Service
+   
+2. **F-PLUGIN-01, F-PLUGIN-02 (Zeilen 848-860):** Plugin-System-Architektur → architecture.md
+   - Plugin-Schnittstelle, Manifest-Format, Lifecycle-Hooks, Abhängigkeiten
+
+3. **F-WF-01 (Zeile 812-815):** Workflow-Engine-Architektur → architecture.md
+   - Hybrid-Ansatz, Code-Engine vs. konfigurierbare Regeln
+
+4. **Alle HTTP-Endpunkt-Spezifikationen:** → architecture.md (API-Contract-Sektion)
+   - `POST /api/auth/login`, `GET /api/companies/{id}`, etc.
+   - Request/Response-Body-Formate
+   - Query-Parameter-Spezifikationen
+   - HTTP-Status-Codes
+
+5. **Alle DB-Schema-Definitionen:** → architecture.md (DB-Schema-Sektion)
+   - Feld-Tabellen mit Typen (F-COMP-01 Zeilen 156-186, F-CONT-01 Zeilen 300-333)
+   - Tabellennamen (`audit_log`, `deletion_log`, `company_contacts`, `user_calendar_visibility`)
+   - `tenant_id`-Feld-Spezifikation
+   - `tsvector`-Index-Spezifikation
+
+6. **Protokoll-Details:** → architecture.md
+   - IMAP4rev1, IMAP IDLE, IMAP MOVE, SMTP-Auth
+   - RFC 5545 (RRULE), RFC 5322 (Threading)
+   - PGP-Verschlüsselung (python-gnupg)
+   - DOMPurify-Sanitization
+   - AES-256-Verschlüsselung für Passwörter
+
+7. **Frontend-Komponenten-Architektur:** → architecture.md (Frontend-Architektur-Sektion)
+   - Komponenten-Namen (`CalendarView`, `KanbanCalendar`, `FileBrowser`, `Breadcrumb`, `ContextMenu`, `ThreadView`)
+   - State-Management (`Multi-Select-State`, `user_calendar_visibility`)
+   - HTML5 Drag & Drop API, XMLHttpRequest
+   - Materialized Path Pattern

+   - Thread-Gruppierung
+
+10. **F-FILE-01 bis F-FILE-04 (Zeilen 955-985):** Duplikate von F-DMS/F-PERM — entfernen oder konsolidieren
+11. **F-SCHED-01 (Zeile 784-792):** Duplikat von F-CORE-07 — konsolidieren
+12. **Appendix A: Historische Anforderungen (Zeilen 2089-2128):** In separates `changelog.md` oder entfernen
+
+### 3.3 Wie die Widersprüche (Plugin vs. Core-Feature) aufgelöst werden können
+
+**Option A: Module sind Core-Features (empfohlen für v1/v2)**
+- Entferne F-PLUGIN-01, F-PLUGIN-02, F-CORE-01 bis F-CORE-13 aus requirements.md
+- Module (Mail, Kalender, DMS, Tags) sind Core-Features mit Requirements
+- Plugin-System ist ein Non-Goal für v1/v2 („Plugin-System für spätere Versionen")
+- Vorteil: Konsistent, weniger Komplexität, schneller implementierbar
+- Nachteil: Weniger Erweiterbarkeit
+
+**Option B: Module sind Plugins**
+- Core-Requirements definieren nur Plugin-Schnittstelle und Core-Infrastruktur
+- Plugin-Requirements (Mail, Kalender, DMS) werden in separate Plugin-Specs ausgelagert
+- Core-Requirements sagen: „Das System unterstützt Plugins. Plugin 'Mail' muss X können. Plugin 'Kalender' muss Y können."
+- Die detaillierten Feature-Spezifikationen (F-MAIL-*, F-CAL-*, F-DMS-*) wandern in Plugin-Requirements
+- Vorteil: Saubere Trennung, Erweiterbarkeit
+- Nachteil: Mehr Dokumentation, mehr Komplexität, Over-Engineering für ein Mini-CRM
+
+**Empfehlung: Option A für v1/v2.**
+Ein Mini-CRM mit 10 concurrent Users braucht kein Plugin-System. Das Plugin-System ist ein Architektur-Non-Goal für v1/v2. Die Module werden als Core-Features implementiert. Wenn Erweiterbarkeit später benötigt wird, kann ein Plugin-System in v3+ hinzugefügt werden. F-PLUGIN-01, F-PLUGIN-02, F-CORE-01 bis F-CORE-13 werden zu Non-Goals.

+## Section 4: Spezifische Konflikte (Tabelle)
+
+| ID/Zeile | Issue | Severity | Vorschlag |
+|----------|-------|----------|-----------|
+| F-PLUGIN-01 (848) vs F-DMS/F-CAL/F-MAIL | Module als Plugins deklariert, aber als Core-Features mit Endpunkten/DB-Schemas spezifiziert | **critical** | Plugin-System als Non-Goal für v1/v2; Module als Core-Features deklarieren |
+| F-FILE-01-04 (955-985) vs F-DMS-01-07 (991-1083) | F-FILE und F-DMS beschreiben dasselbe Modul mit unterschiedlichen IDs. F-FILE-01 (Datei-Explorer) = F-DMS-01 (Ordner-Struktur), F-FILE-03 (PDF-Preview) = F-DMS-04, F-FILE-04 (OnlyOffice) = F-DMS-05 | **critical** | F-FILE-01 bis F-FILE-04 entfernen; durch F-DMS-Referenzen ersetzen |
+| F-FILE-03 (973) vs F-DMS-04 (1033) | Beide spezifizieren PDF-Preview im Browser — Duplikat | **critical** | F-FILE-03 entfernen; F-DMS-04 behalten (detaillierter) |
+| F-FILE-04 (982) vs F-DMS-05 (1047) | Beide spezifizieren OnlyOffice-Integration — Duplikat | **critical** | F-FILE-04 entfernen; F-DMS-05 behalten (detaillierter) |

+| Empfehlung | Requirements bereinigen, ~65% nach architecture.md verschieben, Plugin-System als Non-Goal für v1/v2 |
+
+**Urteil:** Die Datei ist eine Mischung aus Requirements-Spec und Architektur-Dokument. Sie hat den Charakter einer Bauanleitung angenommen. Für eine saubere Trennung sollten ~65% des Inhalts in architecture.md verschoben werden. Die verbleibende requirements.md sollte nur das WAS beschreiben — nicht das HOW.

+## Fix Verification Summary (11 Issues from Round 1)
+
+| # | Issue | Severity (R1) | Fix Status | Evidence |
+|---|-------|---------------|------------|----------|
+| 1 | F-AI-01 (KI-Copilot) missing | CRITICAL | ✅ FIXED | Architecture §8b (lines 1483-1530): API endpoints, RBAC enforcement, DB table `ai_conversations`, frontend integration. Task T09 covers F-AI-01 with 22 acceptance criteria + test_spec. |
+| 2 | F-WF-01 (Hybrid-Workflow-Engine) missing | CRITICAL | ✅ FIXED | Architecture §8c (lines 1538-1620): Hybrid approach (code-engine + configurable), API endpoints, DB tables `workflows`/`workflow_instances`/`workflow_step_history`. Task T09 covers F-WF-01 with 22 acceptance criteria + test_spec. |
+| 3 | Session-Storage contradiction | CRITICAL | ✅ FIXED | §6 (line 200-210): `sessions` table labeled "Audit Trail — primary session store is Redis" with clear note. ADR-05 (line 1871): "Server-side sessions in Redis (primary store), PostgreSQL `sessions` table retains session records as an audit trail." Session creation flow (line 1242-1243): Redis key + PostgreSQL audit record. Consistent across all three locations. |
+| 4 | 19 v1 Features without traceability | MAJOR | ✅ FIXED | All 19 features verified in task_graph requirement_ids: F-NAV-01, F-SET-01, F-UI-01-06, F-UI-08, F-SEC-02, F-SEC-03, F-SCHED-01, F-DATA-03, F-DATA-04, F-DATA-06, F-ENV-01, F-INFRA-02, F-INFRA-03, F-TEST-01 — all present (grep count ≥1). |
+| 5 | F-DOC-01 (Dokumentation) missing | MAJOR | ✅ FIXED | Task T10 covers F-DOC-01: README.md, docs/admin-guide.md, docs/api-overview.md with 3 acceptance criteria + test command. |
+| 6 | F-INFRA-04 (Monitoring & Alerting) missing | MAJOR | ✅ FIXED | Architecture §8d (lines 1662-1710): Health endpoint, Prometheus metrics, alerting rules, structured logging. Task T10 covers F-INFRA-04 with 5 acceptance criteria. |
+| 7 | F-PERF-01 (Performance) missing | MAJOR | ✅ FIXED | Architecture §8e (lines 1714-1770): DB indexing strategy, query optimization, frontend performance, performance tests. Task T10 covers F-PERF-01 with 6 acceptance criteria. |
+| 8 | F-CONT-08 phantom in task_graph | MAJOR | ✅ FIXED | `grep -n 'F-CONT-08' task_graph.json` returns 0 results. Phantom removed. |
+| 9 | api_tokens table not in DB schema | MINOR | ✅ FIXED | DB Schema §2 (line 366-380): `api_tokens` table defined with id, tenant_id, user_id, token_hash, name, scopes (JSONB), expires_at, last_used_at, created_at, revoked_at. Index on (tenant_id, user_id) and (token_hash). |
+| 10 | CSP-Header not mentioned | MINOR | ✅ FIXED | Architecture §6 (lines 1284-1291): Full CSP header in Nginx config, plus X-Content-Type-Options, X-Frame-Options, X-XSS-Protection, HSTS, Referrer-Policy, DOMPurify sanitization. |
+| 11 | Typo line 1033 (```n) | MINOR | ✅ FIXED | `grep -n '```n' architecture.md` returns 0 results. No malformed code fences found. |
+
+**Fix Score: 11/11 resolved.** All critical and major issues from Round 1 are fixed.

+## Original 10 Criteria Re-Check
+
+| # | Kriterium | R1 Result | R2 Result | Change |
+|---|----------|-----------|----------|--------|
+| 1 | Architecture.md deckt alle 10 Bereiche ab | ✅ PASS | ✅ PASS | No change — all 10 areas present, plus 4 new sub-sections (§8b-§8e) |
+| 2 | Task Graph: 6-8 substantielle Tasks | ✅ PASS | ✅ PASS | 10 tasks (was 8). T09 (700 lines) and T10 (500 lines) are substantielle. Acceptable expansion. |
+| 3 | 143/143 Features abgedeckt | ❌ FAIL | ✅ PASS | All 134 v1 features covered (140 total - 6 v2). 0 phantom. Coverage summary count is incorrect (see MINOR-2). |
+| 4 | AGENTS.md: Commands, Forbidden Patterns, Task-Zuweisung | ✅ PASS | ⚠️ PARTIAL | Commands ✅, Forbidden patterns ✅, but Task-Zuweisung table and Phasen-Plan missing T09/T10 (see MAJOR-1). |
+| 5 | Keine Widersprüche arch.md ↔ requirements.md | ⚠️ PARTIAL | ✅ PASS | All gaps closed: F-AI-01 §8b, F-WF-01 §8c, F-INFRA-04 §8d, F-PERF-01 §8e, F-SEC-02 CSP. |
+| 6 | Keine Widersprüche task_graph.json ↔ arch.md | ⚠️ PARTIAL | ✅ PASS | F-CONT-08 phantom removed. api_tokens table in DB schema. Task endpoints match architecture API design. |
+| 7 | Multi-Tenant (tenant_id) konsistent | ✅ PASS | ✅ PASS | No change. All tables have tenant_id. New tables (ai_conversations, workflows, workflow_instances, workflow_step_history) also have tenant_id. |
+| 8 | Plugin-System als v1-Core-Feature | ✅ PASS | ✅ PASS | No change. |
+| 9 | PostgreSQL 16, React 18 SPA, FastAPI | ✅ PASS | ✅ PASS | No change. |
+| 10 | Session-Auth + API-Token separat | ⚠️ PARTIAL | ✅ PASS | Session storage contradiction resolved. Redis primary + PostgreSQL audit trail consistent across §6, ADR-05, and session creation flow. api_tokens table in DB schema. |
+
+**Gesamt: 8 PASS, 1 PARTIAL, 0 FAIL → APPROVED_WITH_SUGGESTIONS**

+
+## New Findings (Round 2)
+
+### MAJOR-1: AGENTS.md not updated for T09 and T10
+
+- **Artifact:** AGENTS.md
+- **Location:** Lines 377-398 (Phasen-Plan + Task Assignment table), Line 484 (Release Gate)
+- **Issue:** AGENTS.md still references only 8 tasks (T01-T08) in 5 phases. The task_graph.json has been expanded to 10 tasks (T01-T10) in 6 phases. The following sections are out of sync:
+  - **Phasen-Plan table** (line 381-385): Missing Phase 6 (T10) and T09 in Phase 3
+  - **Task Assignment table** (line 391-398): Missing rows for T09 and T10
+  - **Release Gate** (line 484): Says "All 8 tasks complete" — should say "All 10 tasks complete"
+  - **Block Rules** (line 412): Says "After 3 blocks (9 tasks)" — should reference 10 tasks
+- **Recommendation:**
+  1. Add T09 to Phasen-Plan Phase 3 (parallel with T04, T05, T06)
+  2. Add Phase 6 with T10 to Phasen-Plan
+  3. Add T09 and T10 rows to Task Assignment table
+  4. Update Release Gate to "All 10 tasks complete"
+  5. Update Block Rules to reference 10 tasks (4 blocks)
+- **Block transition:** NEIN — does not block implementation start, but must be fixed before Phase 3 execution
+
+### MINOR-1: Architecture section numbering (§8b-§8e under §8)
+
+- **Artifact:** architecture.md
+- **Location:** Lines 1483, 1538, 1662, 1714
+- **Issue:** New sections §8b (KI-Integration), §8c (Workflow Engine), §8d (Monitoring), §8e (Performance) are sub-sections of §8 (Deployment Architecture). Topically, KI-Integration and Workflow Engine are architecture concerns, not deployment concerns.
+- **Recommendation:** Consider renumbering as §11 (KI-Integration), §12 (Workflow Engine), or as sub-sections of §1 (System Architecture). Not blocking — content is correct and well-structured.
+
+### MINOR-2: feature_coverage_summary count incorrect
+
+- **Artifact:** task_graph.json
+- **Location:** Line 556 (`"total_features": 143`)
+- **Issue:** The summary states 143 total features, but requirements.md contains 140 unique feature IDs. Of these, 6 are [v2-Plugin] (F-FILE-01-04, F-FILEUI-05-06), leaving 134 v1 features — all covered by tasks. The note says "6 v2-Plugin features excluded" but the total count is wrong (143 should be 140).
+- **Recommendation:** Change `"total_features": 143` to `"total_features": 140` and update the note to say "134 v1 features covered, 6 v2-Plugin features excluded".

+
+## Detailed Fix Verification
+
+### ✅ CRITICAL-1 (FIXED): F-AI-01 — KI-Copilot
+
+**Architecture §8b (lines 1483-1530):**
+- API-First-Design als Grundlage documented ✅
+- 3 API Endpoints: `/api/v1/ai/copilot/query`, `/api/v1/ai/copilot/history`, `/api/v1/ai/copilot/execute` ✅
+- RBAC-Durchsetzung: 5 points (Auth via session, RBAC middleware, field-level permissions, tenant isolation, audit log) ✅
+- Implementation-Modell v1: Query/Execute/History + LLM config via env vars ✅
+- Frontend-Integration: Sidebar entry, chat interface, confirmation dialog ✅
+- DB table `ai_conversations` with tenant_id, user_id, role, content, proposed_actions (JSONB) ✅
+- Test file `test_ai_copilot.py` listed in test tree ✅
+
+**Task T09 (lines 426-467):**
+- F-AI-01 in requirement_ids ✅
+- 7 acceptance criteria for Copilot (query, execute, RBAC, history, audit, tenant, field-level) ✅
+- test_spec with 3 commands + 2 test files ✅
+- Coverage target: 80% ✅
+
+### ✅ CRITICAL-2 (FIXED): F-WF-01 — Hybrid-Workflow-Engine
+
+**Architecture §8c (lines 1538-1620):**
+- Hybrid-Ansatz: Code-Engine (hardcoded Python workflows) + Configurable Engine (user-defined via Admin-UI) ✅
+- 10 API Endpoints for workflow management ✅
+- 3 DB tables: `workflows` (definition with JSONB steps), `workflow_instances` (running), `workflow_step_history` (audit trail) ✅
+- Step JSONB structure documented with example (action, approval, notification types) ✅
+- All tables have tenant_id ✅
+
+**Task T09 (lines 426-467):**
+- F-WF-01 in requirement_ids ✅
+- 14 acceptance criteria for Workflow (CRUD definitions, instances, advance/approve/reject/cancel, event trigger, step history, code-engine, timeout) ✅
+- test_spec includes `test_workflows.py` ✅
+
+### ✅ CRITICAL-3 (FIXED): Session-Storage Contradiction
+
+- **§6 sessions table (line 200):** Labeled "Audit Trail — primary session store is Redis" ✅
+- **Note (line 210):** "Session lookup at runtime uses Redis (`session:{id}` with TTL=8h). This PostgreSQL table is an immutable audit trail." ✅
+- **Session creation flow (lines 1242-1243):** "Create session in Redis (key: `session:{session_id}`, TTL=8h)" + "Write session record to PostgreSQL `sessions` table for audit trail" ✅
+- **ADR-05 (line 1871):** "Server-side sessions in Redis (primary store for fast lookup), session ID in HttpOnly+Secure+SameSite=Strict cookie. PostgreSQL `sessions` table retains session records as an audit trail" ✅
+- **All three locations are now consistent:** Redis = primary session store (fast lookup, TTL), PostgreSQL = immutable audit trail ✅
+

+## Feature Coverage Cross-Check (Programmatic)
+
+**Method:** Regex extraction of all `F-[A-Z]+-[0-9]+` patterns from requirements.md and task_graph.json, set difference.
+
+| Metric | Count |
+|--------|-------|
+| Unique features in requirements.md | 140 |
+| Unique features in task_graph.json | 136 |
+| Missing from task_graph (v2-Plugin, legitimately excluded) | 4 (F-FILE-02, F-FILE-03, F-FILE-04, F-FILEUI-06) |
+| Phantom features (in task_graph but not in requirements) | 0 |
+| v1 features covered | 134/134 (100%) |
+| v2 features excluded | 6/6 (F-FILE-01-04, F-FILEUI-05-06) |
+
+**Note:** F-FILE-01 and F-FILEUI-05 appear in requirements.md as [v2-Plugin] but are NOT in any task's requirement_ids array — they only appear in the coverage summary note text. This is correct behavior.

+## Review Metadata
+
+- **Files reviewed:** architecture.md (1904 lines), task_graph.json (571 lines), AGENTS.md (542 lines), requirements.md (2142 lines, reference), quality-gate-phase2.md (383 lines, previous review)
+- **Cross-check method:** Programmatic Feature-ID extraction + set difference (Python regex/grep), targeted section reads
+- **Review method:** Full verification of all 11 Round-1 issues + re-check of 10 original criteria + new issue detection
+- **Tools used:** text_editor (read), code_execution_tool (grep/sed/python cross-check)
+
+---
+
+## Verdict
+
+**✅ APPROVED_WITH_SUGGESTIONS**
+
+All 11 issues from Round 1 are resolved. All 10 original criteria pass (8 PASS, 1 PARTIAL due to AGENTS.md gap). No critical issues remain. One major issue (AGENTS.md not updated for T09/T10) is non-blocking for implementation start but must be fixed before Phase 3 execution.
+
+**Phase transition: APPROVED** — Implementation may begin. AGENTS.md update should be done in parallel with T01 implementation.

+# Quality Gate Review — Phase 2 Architecture (Round 3)
+
+**Project:** leocrm
+**Date:** 2026-06-28
+**Reviewer:** Quality Reviewer (automated)
+**Scope:** v1/v2 separation fix verification after Round 2
+
+---
+
+## VERDICT: APPROVED_WITH_SUGGESTIONS
+
+| Severity | Count |
+|----------|-------|
+| Critical | 0 |
+| Major | 1 |
+| Minor | 3 |
+| Suggestion | 2 |
+
+---
+
+## 1. V1/V2 SEPARATION — ✅ PASS
+
+**Methodology:** Extracted all `requirement_ids` from each v1 task (T01, T02, T03, T07, T09, T10) and cross-checked against v2 feature prefixes (F-CAL-*, F-DMS-, F-FILE*, F-FILEUI-*, F-LINK-*, F-MAIL-*, F-PERM-*, F-TAG-*).
+
+**Result:** No v2 feature IDs appear in any v1 task.
+
+| Task | Scope | V2 Features Found |
+|------|-------|-------------------|
+| T01 | v1 | ✓ None |
+| T02 | v1 | ✓ None |
+| T03 | v1 | ✓ None |
+| T07 | v1 | ✓ None |
+| T09 | v1 | ✓ None |
+| T10 | v1 | ✓ None |
+
+**Feature ID extraction per v1 task:**
+- T01: F-CORE-*, F-AUTH-*, F-SEC-*, F-INFRA-*, F-INT-*, F-SCHED-*, F-TEST-01 (25 reqs)
+- T02: F-COMP-*, F-CONT-*, F-DATA-*, F-MIG-*, F-CORE-*, F-SEARCH-*, F-TEST-01 (25 reqs)
+- T03: F-PLUGIN-*, F-CORE-*, F-TEST-01 (7 reqs)
+- T07: F-AUTH-*, F-COMP-*, F-CONT-*, F-CORE-*, F-SEARCH-*, F-A11Y-*, F-INT-*, F-NAV-*, F-SET-*, F-UI-*, F-DATA-*, F-TEST-01 (38 reqs)
+- T09: F-AI-01, F-WF-01, F-CORE-*, F-TEST-01 (5 reqs)
+- T10: F-INFRA-*, F-PERF-01, F-DOC-01, F-ENV-01, F-TEST-01 (8 reqs)
+
+---
+
+## 2. V1 FEATURE COVERAGE — ✅ PASS
+
+**Methodology:** Extracted 73 v1 features from requirements.md (70 with `[v1]` header markers + 3 F-A11Y features marked `[v1]`). Cross-checked against architecture.md and task_graph.json.
+
+### Architecture Coverage
+- **V1 features in architecture.md:** 73/73 ✅
+- All v1 features are referenced in the architecture document.
+
+### Task Graph Coverage
+- **V1 features assigned to v1 tasks:** 73/73 ✅
+- Zero v1 features missing from task assignments.
+- The task_graph contains 3 additional IDs (F-A11Y-01, F-A11Y-02, F-A11Y-03) in T07 that are correctly marked `[v1]` in requirements.md.
+
+**Feature count reconciliation:**
+- Requirements.md: 73 v1 features (marked `[v1]`) + 70 v2 features (marked `[v2-Plugin]` or unmarked) = 143 total
+- Wait — our regex found 140 unique header features (73 v1 + 67 v2 headers). However, 3 v2 features (F-A11Y-01/02/03) are actually v1. The `[v2-Plugin]` marker on some features was not caught by the initial `[v1]`/`[v2]` regex because it uses `[v2-Plugin]` format. This does not affect the review outcome — all 73 v1 features are accounted for.
+
+---
+
+## 3. DEPENDENCY CHAIN — ✅ PASS
+
+**Methodology:** Extracted `dependencies` field from all v1 tasks and verified no v2 task appears as a dependency.
+
+| V1 Task | Dependencies | All V1? |
+|---------|-------------|---------|
+| T01 | [] | ✓ (no deps) |
+| T02 | [T01] | ✓ |
+| T03 | [T01] | ✓ |
+| T07 | [T01, T02] | ✓ |
+| T09 | [T01, T02] | ✓ |
+| T10 | [T01, T02] | ✓ |
+
+**Critical check:** T10 does NOT depend on T08, T08a, T08b, T08c, or any v2 task. ✅
+
+**V2 task dependencies (for reference):**
+- T04: [T01, T03] — v1 deps only ✅
+- T05: [T01, T03] — v1 deps only ✅
+- T06: [T01, T03] — v1 deps only ✅
+- T08a: [T04, T07] — v2+v1 deps (expected) ✅
+- T08b: [T05, T07] — v2+v1 deps (expected) ✅
+- T08c: [T06, T07] — v2+v1 deps (expected) ✅
+- T11: [T01, T03] — v1 deps only ✅
+
+**Conclusion:** V1 tasks can execute independently without any v2 task. The dependency chain is clean.
+
+---
+
+## 4. TASK SIZING — ✅ PASS
+
+**Methodology:** Counted `requirement_ids` and `acceptance_criteria` per task. Threshold: ≤40 each.
+
+| Task | Reqs | ACs | Overloaded? |
+|------|------|-----|-------------|
+| T01 | 25 | 26 | ✅ No |
+| T02 | 25 | 24 | ✅ No |
+| T03 | 7 | 14 | ✅ No |
+| T04 | 11 | 26 | ✅ No |
+| T05 | 19 | 30 | ✅ No |
+| T06 | 20 | 40 | ✅ No (at limit) |
+| T07 | 38 | 32 | ✅ No |
+| T08a | 23 | 12 | ✅ No |
+| T08b | 13 | 11 | ✅ No |
+| T08c | 16 | 18 | ✅ No |
+| T09 | 5 | 22 | ✅ No |
+| T10 | 8 | 18 | ✅ No |
+| T11 | 16 | 14 | ✅ No |
+
+**Note:** T06 has exactly 40 ACs (at the limit) and T07 has 38 reqs (close to limit). Recommend monitoring during implementation but not blocking.
+
+---
+
+## 5. ARCHITECTURE V1/V2 MARKERS — ⚠️ PARTIAL
+
+**Methodology:** Searched architecture.md for section headers containing v2 domain names with v2/Plugin Phase markers.
+
+### V2 Section Markers Found
+| Domain | V2-Marked Sections | Status |
+|--------|-------------------|--------|
+| DMS | 2 | ✅ `### DMS Plugin Tables (v2 — Plugin Phase)`, `### DMS Plugin Endpoints (v2 — Plugin Phase)` |
+| Calendar | 1 | ✅ `### Calendar Plugin Tables (v2 — Plugin Phase)` |
+| Mail | 1 | ✅ `### Mail Plugin Tables (v2 — Plugin Phase)` |
+| Tag | 0 | ⚠️ Missing v2 marker |
+| Permission | 0 | ⚠️ Missing v2 marker |
+| File | 0 | ⚠️ Missing v2 marker |
+
+### V1 Feature References in Architecture
+- **73/73 v1 features referenced** ✅
+- All v1 feature IDs (including F-A11Y-01/02/03) appear in architecture.md.
+
+### V2 Feature References in Architecture
+- **48/70 v2 features explicitly referenced** (22 missing)
+- Missing v2 feature IDs in architecture.md:
+  - F-CAL-06, F-CAL-07, F-CAL-08, F-CAL-12, F-CAL-14, F-CAL-15
+  - F-FILE-01, F-FILE-02, F-FILE-03, F-FILE-04
+  - F-FILEUI-02, F-FILEUI-03, F-FILEUI-05, F-FILEUI-06
+  - F-LINK-02, F-LINK-03, F-LINK-04, F-LINK-06
+  - F-PERM-01, F-PERM-02, F-PERM-04
+  - F-TAG-03
+
+**Assessment:** The missing v2 feature references in architecture.md are a MINOR issue. The architecture document covers the plugin system architecture generically (plugin manifest, plugin DB migrations, UI plugin framework). Individual v2 feature IDs are more relevant at the task/implementation level. However, the missing v2 section markers for Tag, Permission, and File domains should be added for completeness.
+
+---
+
+## 6. AGENTS.md COMPLETENESS — ✅ PASS
+
+**Methodology:** Verified all 13 task IDs (T01-T11, T08a, T08b, T08c) are referenced in AGENTS.md.
+
+| Task ID | In AGENTS.md |
+|---------|-------------|
+| T01 | ✅ |

+| T08b | ✅ |
+| T08c | ✅ |
+| T09 | ✅ |
+| T10 | ✅ |
+| T11 | ✅ |
+
+- V1 phase mentioned: ✅ (18 occurrences of 'v1')
+- V2 phase mentioned: ✅ (16 occurrences of 'v2')
+- Phase plan shows v1 and v2 phases separately: ✅

+- F-FILEUI-05: Upload-Progress-Anzeige (DMS plugin)
+- F-FILEUI-06: Drag & Drop zwischen Ordnern (DMS plugin)
+
+**Impact:** These requirements exist in requirements.md but have no task ownership. They may be implicitly covered by T04 (DMS backend) and T08a (DMS UI), but without explicit `requirement_ids` entries, there is no traceability and risk of implementation gaps.
+
+**Recommendation:** Add F-FILE-01 through F-FILE-04 to T04's `requirement_ids` and F-FILEUI-05, F-FILEUI-06 to T08a's `requirement_ids`. Alternatively, create a dedicated T08d task for the file-explorer UI features if T08a is already at capacity (23 reqs).

+
+### Finding 2 — MINOR: Missing V2 Section Markers for Tag, Permission, and File Domains
+
+**Severity:** Minor
+**Artifact:** architecture.md
+**Location:** Section headers
+**Issue:** Three v2 domains lack explicit "v2 — Plugin Phase" section markers:
+- Tag: No v2-marked section header found
+- Permission: No v2-marked section header found
+- File (DMS File Explorer): No v2-marked section header found
+
+The architecture document has v2 markers for DMS, Calendar, and Mail tables/endpoints, but not for Tag, Permission, or File-specific sections.
+
+**Recommendation:** Add v2 section markers for:
+- `### Tag Plugin Tables (v2 — Plugin Phase)`
+- `### Tag Plugin Endpoints (v2 — Plugin Phase)`
+- `### Permission Plugin Tables (v2 — Plugin Phase)`
+- `### Permission Plugin Endpoints (v2 — Plugin Phase)`
+- `### File Explorer (DMS) (v2 — Plugin Phase)`
+
+---
+
+### Finding 3 — MINOR: 22 V2 Features Not Explicitly Referenced in Architecture.md
+
+**Severity:** Minor
+**Artifact:** architecture.md
+**Location:** Feature ID references
+**Issue:** 22 of 70 v2 features are not explicitly referenced by feature ID in architecture.md. While the architectural concepts (plugin system, DMS tables, etc.) are described, individual feature-level traceability is missing for these 22 features.
+
+**Impact:** Low — v2 is the plugin phase and the architecture covers the plugin system generically. Individual feature IDs are more relevant at implementation time. However, adding references improves traceability.
+
+**Recommendation:** Add feature ID references to the relevant architecture sections for the 22 missing v2 features listed in Section 5 above.
+
+---
+
+### Finding 4 — MINOR: T06 at AC Limit (40/40)
+
+**Severity:** Minor
+**Artifact:** task_graph.json
+**Location:** T06 (Mail Plugin)
+**Issue:** T06 has exactly 40 acceptance criteria, hitting the threshold limit. While not exceeding, this is a large task that may be difficult to implement and test in a single block.
+
+**Recommendation:** Consider splitting T06 into T06a (core mail: F-MAIL-01 through F-MAIL-10) and T06b (advanced mail: F-MAIL-11 through F-MAIL-19) if implementation proves unwieldy.
+
+---
+
+### Finding 5 — SUGGESTION: T07 Has 38 Requirements (Near Limit)
+
+**Severity:** Suggestion
+**Artifact:** task_graph.json
+**Location:** T07 (Frontend SPA)
+**Issue:** T07 has 38 requirements, close to the 40 limit. This is the frontend SPA task covering all v1 UI features.
+
+**Recommendation:** Monitor during implementation. If T07 becomes too large, consider splitting into T07a (layout, navigation, core UI) and T07b (company/contact UI, search, data tables).
+
+---
+
+### Finding 6 — SUGGESTION: V2 Feature Marker Format Inconsistency
+
+**Severity:** Suggestion
+**Artifact:** requirements.md
+**Location:** Feature headers
+**Issue:** V1 features use `[v1]` marker format, but v2 features use `[v2-Plugin]` format. The regex `\[v2\]` does not match `[v2-Plugin]`, which initially caused 0 v2 features to be detected. This is a formatting inconsistency.
+
+**Recommendation:** Standardize marker format — either all use `[v1]`/`[v2]` or all use `[v1-Core]`/`[v2-Plugin]`. This improves automated parsing reliability.
+

+
+---
+
+## NEXT STEPS
+
+1. **MAJOR — Fix before v2 implementation:** Add F-FILE-01 through F-FILE-04 and F-FILEUI-05, F-FILEUI-06 to appropriate v2 task `requirement_ids` in task_graph.json.
+2. **MINOR — Improve before v2 implementation:** Add v2 section markers for Tag, Permission, and File domains in architecture.md.
+3. **MINOR — Improve traceability:** Add the 22 missing v2 feature ID references to architecture.md sections.
+4. **Non-blocking:** T06 at AC limit and T07 near req limit — monitor during implementation.
+
+**Phase Gate Decision:** The v1 scope is clean, complete, and correctly separated from v2. The dependency chain allows independent v1 execution. All 10 original criteria pass. The single MAJOR issue (6 unassigned v2 features) does not block v1 implementation but should be resolved before v2 work begins.
+
+**This phase gate is APPROVED WITH SUGGESTIONS. V1 implementation may proceed.**

+- Keine Micro-Tasks ✅
+
+---
+
+### ❌ Kriterium 3: Feature Coverage 143/143 (FAIL — CRITICAL)
+
+**Cross-Check-Ergebnis (programmatisch durchgeführt):**
+
+- **Requirements.md:** 143 eindeutige Feature-IDs
+- **Task Graph:** 114 eindeutige Feature-IDs in requirement_ids arrays
+- **Fehlend:** 30 Features in requirements.md aber NICHT in task_graph.json
+- **Phantom:** 1 Feature in task_graph.json aber NICHT in requirements.md (F-CONT-08)
+
+#### Klassifikation der 30 fehlenden Features:
+
+**Kategorie A: v2-Scope (6 Features — legitimerweise ausgeschlossen)**
+
+| Feature | Beschreibung | Tag |
+|---------|-------------|-----|
+| F-FILE-01 | Datei-Explorer | [v2-Plugin] |
+| F-FILE-02 | Datei-Sharing | [v2-Plugin] |
+| F-FILE-03 | PDF-Preview | [v2-Plugin] |
+| F-FILE-04 | OnlyOffice-Integration | [v2-Plugin] |
+| F-FILEUI-05 | Upload-Progress-Anzeige | [v2-Plugin] |
+| F-FILEUI-06 | Drag & Drop zwischen Ordnern | [v2-Plugin] |
+
+→ Diese 6 Features sind als [v2-Plugin] markiert und korrekterweise nicht in v1-Tasks enthalten. Funktionalität ist teilweise durch F-DMS-XX und F-FILEUI-01-04 abgedeckt.
+
+**Kategorie B: Implizit abgedeckt, aber Feature-ID fehlt in task_graph (19 Features — Traceability-Gap)**
+
+| Feature | Beschreibung | Implizit gedeckt durch | Severity |
+|---------|-------------|----------------------|----------|
+| F-DATA-03 | Daten-Validierung | Pydantic schemas in allen Tasks | MAJOR |
+| F-DATA-04 | PostgreSQL als Datenbank | ADR-01, gesamte DB Schema | MAJOR |
+| F-DATA-06 | ARIA-Rollen auf DataTable | F-A11Y-01/02/03 in T07 | MAJOR |
+| F-ENV-01 | Environments & Secrets | .env.example in Architecture §8 | MAJOR |
+| F-INFRA-02 | Backup & Restore | Architecture §8 Backup section | MAJOR |
+| F-INFRA-03 | Logging | LOG_LEVEL in .env.example | MAJOR |
+| F-NAV-01 | Navigation Sidebar | T07 Layout Shell (Sidebar) | MAJOR |
+| F-SCHED-01 | Background-Jobs | T01 ARQ Job Queue | MAJOR |
+| F-SEC-02 | XSS-Schutz & Input-Sanitization | DOMPurify, Pydantic validation | MAJOR |
+| F-SEC-03 | Session-Timeout | T01 Auth (8h timeout) | MAJOR |
+| F-SET-01 | Einstellungen als Baum-Menü | T07 Settings Feature (SettingsTree) | MAJOR |
+| F-TEST-01 | Testing-Strategie | Architecture §9 + AGENTS.md | MAJOR |
+| F-UI-01 | Responsive Design | T07 Tailwind responsive breakpoints | MAJOR |
+| F-UI-02 | Internationalisierung | T07 i18n setup (de/en) | MAJOR |
+| F-UI-03 | Error-Handling & Toast | T07 Toast component | MAJOR |
+| F-UI-04 | Loading-States | T07 Skeleton component | MAJOR |
+| F-UI-05 | Empty-States | T07 EmptyState component | MAJOR |
+| F-UI-06 | Confirmation-Dialogs | T07 ConfirmDialog | MAJOR |
+| F-UI-08 | Datenansichten Tabelle/Karten/Liste | T07 TanStack Table | MAJOR |
+
+→ Diese 19 Features sind funktional durch die Tasks abgedeckt, aber ihre Feature-IDs sind NICHT in den `requirement_ids` Arrays der Tasks gelistet. **Die Traceability ist broken.** Jede Anforderung muss explizit einem Task zugeordnet sein.
+
+**Kategorie C: Völlig unabgedeckt — v1 Features ohne Task und ohne Architecture (5 Features — CRITICAL)**
+
+| Feature | Beschreibung | Status | Severity |
+|---------|-------------|--------|----------|
+| **F-AI-01** | KI-Copilot mit voller API-Kontrolle [v1] | ❌ KEIN Task, KEINE Architecture | **CRITICAL** |
+| **F-WF-01** | Hybrid-Workflow-Engine [v1] | ❌ KEIN Task, KEINE Architecture | **CRITICAL** |
+| F-DOC-01 | Dokumentation [v1] | ❌ KEIN Task | MAJOR |
+| F-INFRA-04 | Monitoring & Alerting [v1] | ❌ Nicht abgedeckt | MAJOR |
+| F-PERF-01 | Performance [v1] | ❌ Nicht abgedeckt | MAJOR |
+
+**Detailanalyse F-AI-01 (KI-Copilot):**
+- Requirements sagen: "KI-Copilot von Anfang an einplanen" + "Architektur muss KI-Integration von vornherein unterstützen"
+- Architecture.md erwähnt nur API-First-Design (F-CORE-06), aber hat KEINE Sektion für KI-Integration
+- Task Graph hat keinen Task für KI-Copilot
+- Der Copilot benötigt API-Zugriff mit RBAC-Respektierung — die API existiert, aber kein Task implementiert die Copilot-Integration
+- **Erforderliche Aktion:** Architektur um KI-Integration-Sektion erweitern + Task für KI-Copilot API-Endpunkt hinzufügen (oder als Teil von T01/T02 als API-First-Design-Nachweis)
+
+**Detailanalyse F-WF-01 (Hybrid-Workflow-Engine):**
+- Requirements sagen: "Hybrid-Ansatz: Code-Engine für Kern-Workflows + konfigurierbare Workflow-Regeln"
+- Architecture.md hat Event Bus, aber keine Workflow-Engine
+- Task Graph hat keinen Task für Workflow-Engine
+- **Erforderliche Aktion:** Architektur um Workflow-Engine-Sektion erweitern + Task hinzufügen (oder bestehenden Task erweitern)
+
+#### Phantom Feature
+
+| Feature | In task_graph | In requirements.md | Issue |
+|---------|--------------|-------------------|-------|
+| F-CONT-08 | ✅ T02 requirement_ids | ❌ Nicht vorhanden | Phantom — vermutlich GDPR-Delete für Contacts, das eigentlich F-COMP-08 ist (bereits gelistet) |
+
+---
+
+### ✅ Kriterium 4: AGENTS.md (PASS)
+
+**Build/Test Commands:**
+- Backend: venv setup, uvicorn, alembic, pytest, pytest-cov, mypy, ruff ✅
+- Frontend: npm install, dev, build, vitest, tsc, eslint ✅
+- Docker Compose: build, up, logs, down, config validate ✅
+- E2E: Playwright install + test ✅
+
+**Forbidden Patterns:**
+- Backend: 14 Forbidden Patterns (SQLite, Jinja2, Cross-Tenant, Plaintext Passwords, JWT, Naive Datetime, Integer IDs, Hard-Delete ohne GDPR, Manual Tenant Filter, Sync I/O, Raw SQL, Secrets in Code, Unvalidated Input, Missing Audit Log, Plugin Tables ohne tenant_id) ✅
+- Frontend: 10 Forbidden Patterns (Class Components, Inline Styles, Hardcoded Strings, Manual Fetch, Server Data in Zustand, `any` Types, Missing ARIA, Touch Targets <44px, Direct DOM, Unsafe HTML) ✅
+- Deployment: 5 Forbidden Patterns (Root in Container, Exposed DB Port, No Health Check, No Volume, Secrets in compose) ✅
+
+**Task-Zuweisung:**
+- 5-Phasen-Plan mit Parallelisierung ✅
+- Task-to-Subagent Mapping (alle implementation_engineer) ✅
+- Block Rules (max 3 Tasks/Block, quality_reviewer nach Block) ✅
+- Quality Gates (Per-Task, Phase, Release) ✅
+

+- F-AI-01 fordert KI-Integration → Architecture hat keine KI-Sektion (CRITICAL)
+- F-WF-01 fordert Workflow-Engine → Architecture hat keine Workflow-Sektion (CRITICAL)
+- F-SEC-02 fordert CSP-Header → Architecture erwähnt keinen CSP-Header (MINOR)

+
+- Task-API-Endpoints ↔ Architecture API Design: Konsistent ✅
+- Task-DB-Models ↔ Architecture DB Schema: Konsistent ✅
+- Task-Plugin-Architecture ↔ Architecture Plugin Section: Konsistent ✅
+- Task-Dependencies ↔ Architecture Service Dependencies: Konsistent ✅
+- **F-CONT-08** in T02 requirement_ids existiert nicht in requirements.md (Phantom) — MINOR
+- `api_tokens` table in Architecture §6 erwähnt, aber nicht in DB Schema §2 — MINOR
+
+---
+
+### ✅ Kriterium 7: Multi-Tenant konsistent (PASS)
+
+- DB Schema: Jede Tabelle hat `tenant_id UUID FK→tenants.id` ✅
+  - Core: tenants, users, user_tenants, roles, sessions, companies, contacts, company_contacts, audit_log, deletion_log, notifications, password_reset_tokens, plugins ✅
+  - DMS: dms_folders, dms_files, file_links, folder_permissions, file_shares, share_links ✅

+- Plugin Tables MUST include tenant_id — migration validator enforces ✅
+- AGENTS.md Forbidden: "Plugin Tables without tenant_id" ✅
+- Task T01 acceptance criteria: "Cross-tenant access auf company → 404" ✅
+
+---
+
+### ✅ Kriterium 8: Plugin-System als v1-Core-Feature (PASS)
+
+- Architecture §4: Vollständige Plugin-Architektur (Manifest, Lifecycle, Event Bus, DI, UI Framework) ✅
+- ADR-03: Built-in plugins with manifest-driven registration ✅
+- Task T03: Plugin System Framework (install/activate/deactivate/uninstall, migrations, UI registry) ✅
+- Tasks T04-T06: Plugin-Implementierungen (DMS+Tags, Calendar, Mail) ✅
+- Plugin Endpoints in API Design ✅
+- AGENTS.md: Plugin structure in conventions ✅
+- Nicht als Non-Goal markiert ✅
+
+---
+
+### ✅ Kriterium 9: PostgreSQL 16, React 18 SPA, FastAPI (PASS)
+
+- Docker Compose: `postgres:16-alpine` ✅
+- Frontend Stack: React 18, Vite, React Router v6 ✅
+- Backend: FastAPI + Uvicorn ✅
+- ADR-01: PostgreSQL 16 instead of SQLite ✅
+- AGENTS.md Forbidden: ❌ SQLite, ❌ Jinja2 ✅
+- Keine SQLite-Referenzen in gesamter Architektur ✅
+- Keine Jinja2-Referenzen in gesamter Architektur ✅
+
+---
+
+### ⚠️ Kriterium 10: Session-based Auth + API-Token separat (PARTIAL — CRITICAL)
+
+**Session-based Auth:**
+- Architecture §6: Session in `sessions` table, HttpOnly+Secure+SameSite=Strict cookie ✅
+- ADR-05: Session-based Auth instead of JWT ✅
+- AGENTS.md Forbidden: ❌ JWT Tokens ✅
+- Password hashing: bcrypt cost=12 ✅
+- CSRF: SameSite=Strict + Origin-Header-Validierung ✅
+
+**⚠️ CRITICAL CONTRADICTION — Session Storage:**
+- Architecture §6 (line 1116): "Create session in `sessions` table" → PostgreSQL
+- ADR-05 (line 1437): "Server-side sessions in Redis" + "Session data in Redis for fast lookup"
+- DB Schema (lines 193-200): `sessions` table definiert mit id, user_id, tenant_id, csrf_token, expires_at
+- **Widerspruch:** Section 6 sagt PostgreSQL `sessions` table, ADR-05 sagt Redis. Es ist unklar, ob Sessions in Redis ODER PostgreSQL ODER beiden gespeichert werden.
+- **Erforderliche Aktion:** Klären und konsistent dokumentieren: Redis für Session-Lookup (fast) + PostgreSQL für Persistenz (survival)? Oder nur PostgreSQL? ADR-05 muss mit Section 6 übereinstimmen.
+
+**API Tokens:**
+- Architecture §6 erwähnt `api_tokens` table (user_id, token_hash, name, scopes, expires_at) ✅
+- Markiert als "post-MVP, but architecture supports it" ✅
+- `api_tokens` table NICHT in DB Schema §2 definiert — MINOR
+- Token auth via `Authorization: Bearer <token>` ✅
+- Token respektiert RBAC und tenant isolation ✅

+## Severity Summary
+
+| Severity | Count | Details |
+|----------|-------|--------|
+| **CRITICAL** | 3 | F-AI-01 fehlt, F-WF-01 fehlt, Session-Storage-Widerspruch |
+| **MAJOR** | 5 | 19 Features ohne Traceability, F-DOC-01 fehlt, F-INFRA-04 fehlt, F-PERF-01 fehlt, F-CONT-08 Phantom |

+
+---
+
+## Findings (Strukturiert)
+
+### CRITICAL-1: F-AI-01 (KI-Copilot) — V1 Feature komplett fehlt
+- **Artifact:** architecture.md, task_graph.json
+- **Location:** F-AI-01 in requirements.md ist [v1], aber kein Task und keine Architecture-Sektion
+- **Issue:** Requirements fordern KI-Copilot mit API-Kontrolle und RBAC-Respektierung. Weder Architecture.md noch Task Graph enthalten einen Task oder eine Sektion dafür.
+- **Recommendation:**
+  1. Architecture.md um Sektion "KI-Integration" erweitern: API-First-Design als Grundlage, KI-Copilot API-Endpoint (`/api/v1/ai/copilot`), RBAC-Durchsetzung via bestehende Middleware
+  2. Task Graph: Neuen Task T09 hinzufügen ODER T01/T02 erweitern um KI-Copilot API-Endpoint
+  3. F-AI-01 zu requirement_ids des entsprechenden Tasks hinzufügen
+- **Block transition:** JA
+
+### CRITICAL-2: F-WF-01 (Hybrid-Workflow-Engine) — V1 Feature komplett fehlt
+- **Artifact:** architecture.md, task_graph.json
+- **Location:** F-WF-01 in requirements.md ist [v1], aber kein Task und keine Architecture-Sektion
+- **Issue:** Requirements fordern Hybrid-Workflow-Engine (Code-Engine + konfigurierbare Regeln). Architecture hat nur Event Bus, keine Workflow-Engine.
+- **Recommendation:**
+  1. Architecture.md um Sektion "Workflow Engine" erweitern: Code-basierte Kern-Workflows + konfigurierbare User-Workflows
+  2. DB Schema: `workflows`, `workflow_steps`, `workflow_instances` Tabellen
+  3. Task Graph: Neuen Task hinzufügen ODER bestehenden Task erweitern
+  4. F-WF-01 zu requirement_ids hinzufügen
+- **Block transition:** JA
+
+### CRITICAL-3: Session-Storage-Widerspruch (PostgreSQL vs Redis)
+- **Artifact:** architecture.md
+- **Location:** Section 6 (line 1116) vs ADR-05 (line 1437)
+- **Issue:** Section 6 sagt "Create session in `sessions` table" (PostgreSQL). ADR-05 sagt "Server-side sessions in Redis". DB Schema definiert `sessions` table. Unklar, wo Sessions gespeichert werden.
+- **Recommendation:**
+  1. Entscheidung treffen: Redis für Session-Store (fast, mit TTL) ODER PostgreSQL `sessions` table (persistent) ODER beides (Redis für Lookup + PostgreSQL für Audit)
+  2. Architecture §6 und ADR-5 konsistent machen
+  3. Wenn Redis-only: `sessions` table aus DB Schema entfernen oder als Audit-Trail behalten
+  4. Wenn PostgreSQL-only: ADR-05 Rationale anpassen
+- **Block transition:** JA
+
+### MAJOR-1: 19 v1 Features ohne Traceability in task_graph
+- **Artifact:** task_graph.json
+- **Location:** requirement_ids arrays in allen Tasks
+- **Issue:** 19 Features sind funktional durch Tasks abgedeckt, aber ihre IDs fehlen in den requirement_ids Arrays. Traceability ist broken.
+- **Recommendation:** Füge folgende Feature-IDs zu den entsprechenden Tasks hinzu:
+  - T01: F-SCHED-01, F-SEC-02, F-SEC-03, F-INFRA-03
+  - T02: F-DATA-03, F-DATA-04
+  - T07: F-NAV-01, F-SET-01, F-UI-01, F-UI-02, F-UI-03, F-UI-04, F-UI-05, F-UI-06, F-UI-08, F-DATA-06
+  - T08: F-ENV-01, F-INFRA-02
+  - Alle Tasks / übergreifend: F-TEST-01
+- **Block transition:** NEIN, aber vor Implementation beheben
+
+### MAJOR-2: F-DOC-01 (Dokumentation) — V1 Feature ohne Task
+- **Artifact:** task_graph.json
+- **Issue:** F-DOC-01 fordert Dokumentation. Kein Task hat diesen Feature-ID. Architektur erwähnt `docs/admin-guide.md` aber kein Task erstellt Dokumentation.
+- **Recommendation:** T08 um Dokumentations-Task erweitern oder separaten Mini-Task für Admin-Guide + API-Docs hinzufügen
+
+### MAJOR-3: F-INFRA-04 (Monitoring & Alerting) — V1 Feature nicht abgedeckt
+- **Artifact:** architecture.md, task_graph.json
+- **Issue:** Requirements fordern Monitoring & Alerting. Architecture und Task Graph enthalten keins.
+- **Recommendation:** Architecture §8 um Monitoring-Sektion erweitern (z.B. /health endpoint erweitert, Prometheus metrics, Alerting). Task T01 oder T08 um Monitoring erweitern.
+
+### MAJOR-4: F-PERF-01 (Performance) — V1 Feature nicht abgedeckt
+- **Artifact:** architecture.md, task_graph.json
+- **Issue:** Requirements fordern Performance (200k Records, FTS, <2s Response). Architecture hat keine Performance-Sektion oder -Tests.
+- **Recommendation:** Architecture um Performance-Sektion erweitern (DB Indexing Strategy, Query Optimization, Pagination Limits). Task T02 um Performance-Test erweitern (200k seed + list <2s).
+
+### MAJOR-5: F-CONT-08 Phantom in task_graph.json
+- **Artifact:** task_graph.json
+- **Location:** T02 requirement_ids array
+- **Issue:** F-CONT-08 existiert nicht in requirements.md. Vermutlich für GDPR-Delete von Contacts gedacht, was bereits durch F-COMP-08 abgedeckt ist.
+- **Recommendation:** F-CONT-08 aus T02 requirement_ids entfernen. Funktionalität ist bereits durch F-COMP-08 abgedeckt.
+
+### MINOR-1: api_tokens table nicht in DB Schema definiert
+- **Artifact:** architecture.md
+- **Location:** Section 6 erwähnt api_tokens table, aber Section 2 (DB Schema) definiert sie nicht
+- **Recommendation:** api_tokens table in DB Schema aufnehmen (selbst wenn post-MVP)
+
+### MINOR-2: CSP-Header nicht erwähnt
+- **Artifact:** architecture.md
+- **Location:** F-SEC-02 fordert CSP-Header, Architecture erwähnt keins
+- **Recommendation:** Nginx config um Content-Security-Policy Header erweitern
+
+### MINOR-3: Architecture line 1033 — Typo in code fence
+- **Artifact:** architecture.md
+- **Location:** Line 1033: `​```n` statt `​``` `
+- **Recommendation:** `n` entfernen
+
+---
+
+## Next Steps (vor Phase-Übergang erforderlich)
+
+1. **[CRITICAL]** Architecture.md um KI-Integration-Sektion erweitern (F-AI-01)
+2. **[CRITICAL]** Architecture.md um Workflow-Engine-Sektion erweitern (F-WF-01) + entsprechende DB-Tabellen
+3. **[CRITICAL]** Session-Storage-Widerspruch auflösen (Redis vs PostgreSQL) und Architecture §6 + ADR-05 konsistent machen
+4. **[MAJOR]** 19 implizit abgedeckte Feature-IDs zu task_graph.json requirement_ids hinzufügen
+5. **[MAJOR]** F-DOC-01, F-INFRA-04, F-PERF-01 Tasks oder Task-Erweiterungen definieren
+6. **[MAJOR]** F-CONT-08 aus task_graph.json entfernen (Phantom)
+7. **[MINOR]** api_tokens table in DB Schema aufnehmen
+8. **[MINOR]** CSP-Header in Nginx config dokumentieren
+9. **[MINOR]** Typo in architecture.md line 1033 korrigieren
+10. **[SUGGESTION]** feature_coverage_summary in task_graph.json aktualisieren nach Hinzufügen der fehlenden IDs

+# Requirements Review: requirements.md
+
+**Datum:** 2026-06-28  
+**Reviewer:** Requirements Analyst (automatisiert)  
+**Datei:** `/a0/usr/workdir/dev-projects/leocrm/requirements.md`  
+**Zeilen:** 2131  
+**Feature-IDs:** ~141 aktive + 16 archivierte = ~157 total  
+**Status der Datei:** Finalisiert — ready_for_ui (laut Header)
+
+---
+
+## Section 1: Konsistenz-Issues
+
+### 1.1 Plugin-System vs. Core-Feature Widerspruch (CRITICAL)
+
+**Der zentrale Widerspruch der Datei.**
+
+**F-PLUGIN-01 (Zeile 848-851)** deklariert:
+> „Die Module sollen als Plugins realisiert sein, sodass das CRM später durch Plugins erweitert werden kann. Module (Mail, Kalender, Dateien, Tags) sind Plugins."
+
+**F-PLUGIN-02 (Zeile 857-860)** definiert Plugin-Schnittstelle, Lifecycle-Hooks, Plugin-Manifest.
+
+**Gleichzeitig** werden genau diese Module als detaillierte Core-Features mit konkreten HTTP-Endpunkten, DB-Schemas und Test-Szenarien spezifiziert:
+- **F-DMS-01 bis F-DMS-07 (Zeilen 991-1083):** DMS mit `POST /api/dms/folders`, `PATCH /api/dms/files/{id}`, etc.
+- **F-CAL-01 bis F-CAL-18 (Zeilen 1397-1662):** Kalender mit `POST /api/calendar/entries`, `GET /api/calendar/kanban`, etc.
+- **F-MAIL-01 bis F-MAIL-19 (Zeilen 1668-1951):** Mail mit `POST /api/mail/send`, IMAP IDLE, SMTP, PGP, etc.
+- **F-TAG-01 bis F-TAG-04 (Zeilen 1173-1223):** Tags mit `POST /api/tags/assign`, etc.
+
+**Widerspruch:** Wenn Module Plugins sind, dann gehören ihre detaillierten Feature-Spezifikationen (Endpunkte, DB-Schemas, Test-Szenarien) NICHT in die Core-Requirements. Der Core definiert die Plugin-Schnittstelle; das Plugin definiert seine eigenen Features. So wie es jetzt ist, wird das Plugin-System deklariert, aber dann werden die „Plugin-Module" im Core-Requirements-Dokument detailliert spezifiziert — als wären sie Core-Features.
+
+**F-CORE-01 bis F-CORE-13 (Zeilen 864-953)** definieren Core-Infrastruktur (Event Bus, Tenant-Isolation, Plugin-Migration, Service Container, API-First, Async Queue, Caching, Storage, Import/Export, PDF-Gen, Notification Service). Diese sind allesamt Architekturentscheidungen, keine Requirements.
+
+**Fazit:** Die Datei versucht gleichzeitig zu sagen „ diese Module sind Plugins" UND „ diese Module sind Core-Features mit konkreten Implementierungsdetails". Das ist ein architektonischer Widerspruch, der in der Architektur-Phase aufgelöst werden muss — nicht in den Requirements.
+
+### 1.2 Multi-Tenant (F-AUTH-07) vs. ältere Requirements ohne Tenant-Kontext (WARNING)
+
+**F-AUTH-07 (Zeile 135-138)** deklariert Multi-Tenant als v1-Feature:
+> „Das System ist Multi-Tenant-fähig. Mehrere Firmen (Tenants) können im System verwaltet werden. Daten sind pro Tenant isoliert."
+
+**F-CORE-02 (Zeile 871-874)** spezifiziert `tenant_id` auf allen Tabellen, ORM-Middleware für automatisches Query-Scoping.
+
+**Annahme 1 (Zeile 1978):** „v1 ist Multi-Tenant (Multi-Company) — mehrere Firmen (Tenants) im System."
+
+**Aber:** Die früher geschriebenen Requirements (F-AUTH-01 bis F-CONT-07, Zeilen 57-410) erwähnen Tenant-Kontext an keiner Stelle:
+- F-AUTH-01 (Login): kein Tenant-Bezug
+- F-AUTH-03 (User-Verwaltung): kein Tenant-Bezug — aber in Multi-Tenant muss ein User einem Tenant zugeordnet sein
+- F-COMP-01 (Firma anlegen): kein `tenant_id` in Feld-Tabelle (Zeile 156-186)
+- F-CONT-01 (Kontakt anlegen): kein `tenant_id` in Feld-Tabelle (Zeile 300-333)
+- F-COMP-05 (Pagination): kein Tenant-Filter erwähnt
+- F-COMP-06 (Suche): kein Tenant-Scoping erwähnt
+
+**Fazit:** Multi-Tenant wurde später hinzugefügt und die frühen Requirements wurden nicht nachträglich aktualisiert. Das führt zu einer Lücke: Wie verhält sich F-COMP-01 (Firma anlegen) in Multi-Tenant-Kontext? Wird die Firma automatisch dem aktiven Tenant zugeordnet? Kann ein User Firmen in mehreren Tenants anlegen? Diese Fragen sind in den Requirements nicht beantwortet.
+
+### 1.3 KI-Copilot (F-AI-01) mit voller API-Kontrolle vs. ältere UI-only-Flow-Requirements (WARNING)
+
+**F-AI-01 (Zeile 798-806)** deklariert:
+> „Der Copilot hat Zugriff auf die volle API und soll alles steuern können — Daten abfragen, erstellen, bearbeiten, löschen, Aktionen auslösen, Workflows triggern."
+
+**F-CORE-06 (Zeile 899-902)** deklariert API-First:
+> „Alle Core-Features und Plugin-Features sind primär über die API nutzbar. Die UI ist ein API-Client."
+
+**Aber:** Mehrere Requirements beschreiben nur UI-Flows ohne API-Bezug:
+- F-UI-01 (Responsive Design, Zeile 495-503): nur CSS-Breakpoints, kein API-Bezug
+- F-UI-02 (i18n, Zeile 509-517): nur Frontend-Library, kein API-Bezug
+- F-UI-03 (Toast-Notifications, Zeile 523-531): nur Frontend-Komponente
+- F-UI-04 (Loading-States, Zeile 537-545): nur Frontend-State
+- F-UI-05 (Empty-States, Zeile 551-559): nur Frontend-Komponente
+- F-UI-06 (Confirmation-Dialogs, Zeile 565-573): nur Frontend-Modal
+- F-UI-08 (Datenansichten, Zeile 579-582): nur Frontend-Toggle
+
+**Einschränkung:** Diese UI-Requirements sind legitimerweise UI-only — sie beschreiben Präsentationslogik, keine Datenoperationen. F-CORE-06 sollte explizit ausschließen, dass reine UI-Präsentations-Features keine API-Entpunkte benötigen. Aktuell ist die Formulierung „alle Features über API nutzbar" zu breit und suggeriert, dass auch Toast-Notifications einen API-Endpunkt haben müssten.
+
+**Zusätzlicher Befund:** F-AI-01 und F-CORE-06 wurden retroaktiv hinzugefügt. Die ursprünglichen Requirements (v0.1, archiviert in Appendix A, Zeile 2089-2128) beschreiben Jinja2-Templates und SQLite — eine völlig andere Architektur. Die Datei hat also mindestens drei Evolutionsschichten:
+1. v0.1: Single-Tenant, Jinja2, SQLite (archiviert)
+2. v0.3: React SPA, PostgreSQL, RBAC (Hauptteil)
+3. v0.5+: Multi-Tenant, Plugin-System, API-First, KI-Copilot, Mail/Kalender/DMS (hinzugefügt)
+
+Die Schichten wurden nicht vollständig integriert — Rückbezüge fehlen.
+
+### 1.4 Auth-Mechanismus-Unschärfe (WARNING)
+
+**F-AUTH-01 (Zeile 58):** „Session-basierte Auth mit HttpOnly+Secure+SameSite=Strict Cookie"
+
+**F-AUTH-02 (Zeile 72-78):** Test-Szenario sagt „Token wird entfernt" und Akzeptanzkriterium sagt „Server-Token-Blacklist optional für v1" — das suggeriert Token-basierte Auth (JWT?), nicht Session-basierte Auth.
+
+**F-INT-02 (Zeile 714-722):** „API-Endpunkte sind via Session-Cookie authentifiziert" aber erwähnt auch „Optional: API-Key für externe Integrationen".
+
+**F-SEC-03 (Zeile 616-624):** „Session läuft nach 8h ab" — aber „Token gültig <8h" und „Token nach 8h → API gibt 401" — wieder Token-Sprache.
+
+**Fazit:** Die Datei wechselt inkonsistent zwischen „Session" und „Token". Entweder es ist Session-basiert (Cookie + Server-Side Session Store) oder Token-basiert (JWT Stateless). Das muss entschieden und einheitlich formuliert werden.
+
+---
+
+## Section 2: Requirements vs. Bauanleitung Assessment
+
+### 2.1 Enthaltene Implementierungsdetails
+
+Die Datei enthält massiv Implementierungsdetails, die in eine Requirements-Spec nicht gehören:
+
+#### HTTP-Endpunkte (Architektur, nicht Requirement)
+Jedes einzelne Akzeptanzkriterium spezifiziert konkrete HTTP-Endpunkte mit Pfaden, HTTP-Methoden, Query-Parametern und Response-Codes:
+- `POST /api/auth/login` (Zeile 65)
+- `GET /api/companies/{id}` (Zeile 207)
+- `DELETE /api/companies/{id}?cascade=true|false` (Zeile 235)
+- `GET /api/contacts?page=1&page_size=25&sort_by=last_name&sort_order=asc` (Zeile 396)
+- `POST /api/dms/files/upload` (Zeile 1013)
+- `GET /api/dms/files/{id}/preview` (Zeile 1041)
+- `POST /api/calendar/entries` (Zeile 1439)
+- `GET /api/calendar/kanban?period=this_week` (Zeile 1419)
+- `POST /api/mail/send` (Zeile 1693)
+- `GET /api/mail/search?q=angebot&folder=inbox` (Zeile 1709)
+- ...und dutzende weitere
+
+**Problem:** Der Endpunkt-Pfad ist eine Architekturentscheidung. Ein Requirement sagt „User kann sich einloggen" — der Pfad `/api/auth/login` ist Implementierung.
+
+#### DB-Schema-Definitionen (Architektur, nicht Requirement)
+- **F-COMP-01 (Zeilen 156-186):** Vollständige Feld-Tabelle mit Typen: `String(100)`, `Integer`, `Decimal`, `Picklist`, `FK→Company`, `Text(32000)`, etc. — das ist ein DB-Schema
+- **F-CONT-01 (Zeilen 300-333):** Vollständige Feld-Tabelle für Kontakte mit Typen
+- **F-COMP-07 (Zeile 277):** `audit_log` Tabellenname
+- **F-COMP-08 (Zeile 291):** `deletion_log` Tabellenname
+- **F-CONT-07 (Zeile 424):** `company_contacts` N:M-Tabellenname
+- **F-CORE-02 (Zeile 872):** `tenant_id` Feld auf allen Tabellen
+- **F-MAIL-03 (Zeile 1709):** `tsvector`-Index, `mail_body_tsv`, `mail_subject_tsv`
+- **F-CAL-12 (Zeile 1572):** `user_calendar_visibility` Tabellenname
+- **F-CAL-15 (Zeile 1614):** `assigned_to: user_id` Feldname
+
+**Problem:** Feldnamen, -typen und Tabellennamen sind Implementierungsdetails, die in das DB-Schema der Architektur gehören.
+
+#### Technologie-Entscheidungen (Architektur, nicht Requirement)
+- **F-CORE-07 (Zeile 907):** „Celery + Redis oder RQ + Redis" — Technologie-Wahl
+- **F-CORE-08 (Zeile 914):** „Redis als Cache-Backend" — Technologie-Wahl
+- **F-CORE-10 (Zeile 928):** „S3-kompatibles Storage (z.B. MinIO)" — Technologie-Wahl
+- **F-MAIL-02 (Zeile 1693):** „DOMPurify" — Library-Wahl
+- **F-MAIL-12 (Zeile 1846):** „python-gnupg" — Library-Wahl
+- **F-UI-02 (Zeile 517):** „react-i18next" — Library-Wahl
+- **F-DMS-04 (Zeile 1034):** „PDF.js" — Library-Wahl
+- **F-DATA-03 (Zeile 459):** „Pydantic-Schemas" — Library-Wahl
+- **F-INFRA-03 (Zeile 666):** „Python logging mit JSON-Formatter" — Library-Wahl

+#### Protokoll-Details (Architektur, nicht Requirement)
+- **F-MAIL-01 (Zeile 1670):** „IMAP4rev1 (RFC 3501)", „IMAP IDLE (RFC 2177)"
+- **F-MAIL-02 (Zeile 1693):** „multipart/mixed", „SMTP-Versand"
+- **F-MAIL-05 (Zeile 1733):** „References- und In-Reply-To-Header (RFC 5322)"
+- **F-MAIL-18 (Zeile 1929):** „AES-256, Key via Env-Var"
+- **F-CAL-08 (Zeile 1516):** „RRULE (RFC 5545)"
+- **F-CAL-09 (Zeile 1530):** „RFC 5545 konform"
+- **F-MAIL-18 (Zeile 1929):** „IMAP MOVE (RFC 6851)"
+
+#### Frontend-Komponenten-Namen (Architektur, nicht Requirement)
+- **F-CAL-01 (Zeile 1405):** `CalendarView` Komponente
+- **F-CAL-02 (Zeile 1419):** `KanbanCalendar` Komponente

+- **F-FILEUI-04 (Zeile 1363):** Multi-Select-State in `FileBrowser`
+- **F-MAIL-05 (Zeile 1741):** `ThreadView` Komponente
+
+#### Farbcodes und UI-Implementierung (Architektur, nicht Requirement)
+- **F-CAL-06 (Zeile 1485):** `{appointment+normal: "#3B82F6", task+normal: "#F59E0B", *+follow_up: "#F97316", *+private: "#9CA3AF"}` — konkrete Hex-Codes
+- **F-COMP-04 (Zeile 235):** `deleted_at = NOW` — SQL-Ausdruck
+- **F-FILEUI-02 (Zeile 1335):** „Materialized Path oder rekursive Abfrage" — DB-Pattern
+- **F-FILEUI-06 (Zeile 1391):** „HTML5 Drag & Drop API" — Browser-API
+- **F-FILEUI-05 (Zeile 1377):** „XMLHttpRequest (für Progress-Events) oder WebSocket" — Technologie
+
+#### Algorithmus- und Logik-Details (Architektur, nicht Requirement)
+- **F-MAIL-07 (Zeilen 1762-1771):** Regelauswertungs-Reihenfolge, Background-Worker-Trigger
+- **F-MAIL-08 (Zeile 1786):** `vacation_sent_log`, No-Reply-Erkennung: „noreply", „no-reply", „donotreply"
+- **F-CAL-08 (Zeile 1516):** Recurrence-Instanz-Generierung, Exception-Handling
+- **F-CAL-15 (Zeile 1614):** Notification-Versand bei Zuweisung

+
+**Architektur/Implementierung — das HOW:**
+
+1. **F-CORE-01 bis F-CORE-13 (Zeilen 864-953):** Komplett in architecture.md
+   - Event Bus, Tenant-Isolation (`tenant_id`), Plugin-Migration, UI-Plugin-Framework, Service Container/DI, API-First (Endpunkt-Versionierung `/api/v1/`), Async Job Queue (Celery/Redis), Caching (Redis), Storage-Backend (S3/MinIO), Import/Export Service, PDF-Gen, Notification Service

+12. **Appendix A: Historische Anforderungen (Zeilen 2089-2128):** In separates `changelog.md` oder entfernen
+
+### 3.3 Wie die Widersprüche (Plugin vs. Core-Feature) aufgelöst werden können
+
+**Option A: Module sind Core-Features (empfohlen für v1/v2)**
+- Entferne F-PLUGIN-01, F-PLUGIN-02, F-CORE-01 bis F-CORE-13 aus requirements.md
+- Module (Mail, Kalender, DMS, Tags) sind Core-Features mit Requirements
+- Plugin-System ist ein Non-Goal für v1/v2 („Plugin-System für spätere Versionen")
+- Vorteil: Konsistent, weniger Komplexität, schneller implementierbar
+- Nachteil: Weniger Erweiterbarkeit
+
+**Option B: Module sind Plugins**
+- Core-Requirements definieren nur Plugin-Schnittstelle und Core-Infrastruktur
+- Plugin-Requirements (Mail, Kalender, DMS) werden in separate Plugin-Specs ausgelagert
+- Core-Requirements sagen: „Das System unterstützt Plugins. Plugin 'Mail' muss X können. Plugin 'Kalender' muss Y können."
+- Die detaillierten Feature-Spezifikationen (F-MAIL-*, F-CAL-*, F-DMS-*) wandern in Plugin-Requirements
+- Vorteil: Saubere Trennung, Erweiterbarkeit
+- Nachteil: Mehr Dokumentation, mehr Komplexität, Over-Engineering für ein Mini-CRM
+
+**Empfehlung: Option A für v1/v2.**
+Ein Mini-CRM mit 10 concurrent Users braucht kein Plugin-System. Das Plugin-System ist ein Architektur-Non-Goal für v1/v2. Die Module werden als Core-Features implementiert. Wenn Erweiterbarkeit später benötigt wird, kann ein Plugin-System in v3+ hinzugefügt werden. F-PLUGIN-01, F-PLUGIN-02, F-CORE-01 bis F-CORE-13 werden zu Non-Goals.

+# LeoCRM Phase 2 — Security & Data Risk Review
+
+**Reviewer:** Security Data Engineer (A0 Orchestrator)  
+**Date:** 2026-06-28  
+**Project:** leocrm  
+**Phase:** Pre-Implementation (Phase 2 to Phase 3)  
+**Files reviewed:** architecture.md (1939 lines), task_graph.json (v2.0.0, 13 tasks), requirements.md (2142 lines, 143 features)  
+**Scope:** Security architecture, multi-tenant isolation, auth, data persistence, migration, backup/restore, plugin security, dependency risks
+
+---
+
+## VERDICT: APPROVED_WITH_CONCERNS
+
+The architecture is well-structured with strong fundamentals (session-based auth, CSRF protection, CSP headers, RBAC with field-level permissions, audit trail). However, **7 major risks** and **8 minor risks** must be addressed before or during implementation. No critical blocking issues found, but 3 major risks (RLS gap, rate limiting, CORS) should be resolved before Phase 3 start.
+
+| Severity | Count |
+|----------|-------|
+| Critical | 0 |
+| Major | 7 |
+| Minor | 8 |
+
+---
+
+## 1. AUTH SECURITY — Session-Based Auth + API Tokens
+
+### Design Summary
+- **Session store:** Redis (`session:{id}`, TTL=8h) — primary runtime store
+- **Audit trail:** PostgreSQL `sessions` table (immutable, retains all sessions ever created)
+- **Cookie:** `leocrm_session=<id>; HttpOnly; Secure; SameSite=Strict; Path=/`
+- **Password hashing:** bcrypt cost=12
+- **API tokens:** `api_tokens` table (SHA-256 hashed, scoped, expiring) — post-MVP but architecture-ready
+- **Password reset:** Token-based, 24h expiry, hashed storage, no user enumeration, session invalidation on reset
+
+### Assessment: GOOD with concerns
+
+**Positive:**
+- ADR-05 decision is sound: server-side sessions avoid JWT pitfalls (token leakage, no revocation)
+- Immediate session invalidation via Redis key deletion
+- Forensic session audit trail in PostgreSQL (session validation flow checks Redis then PG audit then deny)
+- No user enumeration on login or password reset
+- Cookie flags correctly set (HttpOnly, Secure, SameSite=Strict)
+
+**MAJOR RISK M-01: No brute-force protection on auth endpoints**  
+- **Finding:** No account lockout, failed-attempt tracking, or rate limiting on `POST /api/v1/auth/login` or `POST /api/v1/auth/password-reset/request`
+- **Impact:** An attacker can perform unlimited password guessing attempts. bcrypt cost=12 slows each attempt (~250ms) but does not prevent distributed attacks.
+- **Requirements reference:** F-AUTH-01 has no lockout test scenario. Non-Goals section 18 explicitly excludes rate limiting from v1.
+- **Recommendation:** Add a minimal failed-attempt counter in Redis (`login_failures:{email}`, TTL=15min, threshold=10, lockout 15min) before Phase 3. This is distinct from general rate limiting and is scoped to auth only.
+
+**MINOR RISK m-01: LEOCRM_SECRET_KEY purpose and rotation undefined**  
+- **Finding:** `LEOCRM_SECRET_KEY=<min-32-chars>` is listed in env vars but its usage is not specified (session ID generation? cookie signing? CSRF token generation?). No rotation policy documented.
+- **Recommendation:** Document the secret's purpose in `.env.example` and define a rotation procedure in the admin guide. If used for signing session IDs, rotation invalidates all sessions (acceptable, document it).
+
+**MINOR RISK m-02: No 2FA in v1**  
+- **Finding:** Non-Goals section 13 explicitly excludes 2FA. Acceptable for v1 internal CRM, but should be prioritized post-MVP if exposed to internet.
+- **Recommendation:** Document as post-MVP roadmap item with priority based on exposure.
+
+---
+
+## 2. MULTI-TENANT ISOLATION — Row-Level Security
+
+### Design Summary
+- Every table has `tenant_id` (UUID, NOT NULL on core tables)
+- ORM auto-filtering via SQLAlchemy `before_query` event listener (`do_orm_execute`)
+- `TenantMixin` base class enforces `tenant_id` column on all models
+- Cross-tenant access returns 404 (not 403) to prevent information leakage
+- Plugin tables must include `tenant_id` (validator checks)
+- Tenant switch via `POST /api/v1/auth/switch-tenant`
+
+### Assessment: MODERATE RISK — needs DB-level enforcement
+
+**MAJOR RISK M-02: RLS claimed but only ORM-level filtering implemented**  
+- **Finding:** Architecture line 154 states "PostgreSQL 16 with Row-Level Security for tenant isolation" but the implementation (lines 1232-1240) is **exclusively ORM-level filtering** via SQLAlchemy event listener. No `CREATE POLICY`, `ENABLE ROW LEVEL SECURITY`, or `SET app.current_tenant` session variables are defined.
+- **Impact:** Any query that bypasses the ORM (raw SQL, `session.execute(text(...))`, stored procedures, Alembic migrations, ARQ worker jobs that don't set tenant context) will NOT be tenant-filtered. A single missed `_tenant_filter_disabled` flag or raw query can leak cross-tenant data.
+- **Evidence:** The `before_query` listener checks `if not _tenant_filter_disabled` — this flag must be managed carefully. Any code path that sets it without restoring is a data leak vector.
+- **Recommendation:** 
+  1. Implement PostgreSQL RLS policies as a **defense-in-depth** layer: `CREATE POLICY tenant_isolation ON <table> USING (tenant_id = current_setting('app.current_tenant')::uuid)`
+  2. Set `app.current_tenant` at the beginning of each DB session/transaction from the authenticated session context
+  3. Keep ORM filtering as the primary layer; RLS as the safety net
+  4. This is a design change — should be approved before Phase 3 implementation
+
+**MAJOR RISK M-03: Tenant context propagation to ARQ workers not defined**  
+- **Finding:** Background jobs (exports, mail-sync, reminders, backups) run in a separate worker process. The architecture does not specify how `current_tenant_id()` is set in worker context. If a worker job operates on tenant-scoped data without setting the tenant context, the ORM filter may not apply or may apply incorrectly.
+- **Impact:** Cross-tenant data exposure in background job results (e.g., export contains data from all tenants).
+- **Recommendation:** Define and document tenant context propagation for ARQ workers: each job must carry `tenant_id` in its job context, and the worker must set `current_tenant_id()` before executing any DB queries.
+
+**MINOR RISK m-03: Tenant switch does not validate user-tenant membership**  
+- **Finding:** `POST /api/v1/auth/switch-tenant` updates the session's `tenant_id`. The architecture does not explicitly state that the endpoint validates the user's membership in the target tenant via `user_tenants` table.
+- **Recommendation:** Ensure the switch endpoint checks `user_tenants` membership before updating the session. Add a test case: user attempts to switch to a tenant they don't belong to then 403.
+
+---
+
+## 3. CSRF PROTECTION
+
+### Design Summary
+- SameSite=Strict cookie (browser-level protection)
+- Origin-Header-Validierung middleware (server-side check)
+- Only GET/HEAD/OPTIONS exempt from CSRF check
+- CSRF token stored per session in Redis and PostgreSQL audit table
+
+### Assessment: GOOD
+
+**Positive:**
+- Two-layer CSRF protection (SameSite + Origin validation) is a solid approach
+- SameSite=Strict is the strongest browser-level CSRF defense
+- Origin validation is server-side and not bypassable by client tweaks
+- Test scenarios defined in task_graph.json: "CSRF: POST without Origin header then 403"
+
+**MINOR RISK m-04: CSRF token stored but not validated in requests**  
+- **Finding:** A `csrf_token` is generated and stored per session, but the architecture does not describe a mechanism where the frontend sends the token back (e.g., in a `X-CSRF-Token` header) and the backend validates it. The protection relies entirely on SameSite + Origin.
+- **Impact:** SameSite=Strict + Origin validation is sufficient for v1. The stored CSRF token appears unused.
+- **Recommendation:** Either (a) remove the csrf_token from the session model if SameSite+Origin is the chosen strategy, or (b) implement double-submit cookie pattern for defense-in-depth. Clarify in architecture.
+
+---
+
+## 4. INPUT VALIDATION
+
+### Design Summary
+- Pydantic schemas validate all API inputs (F-DATA-03)
+- XSS protection: server-side Pydantic validation + frontend DOMPurify/escaped rendering (F-SEC-02)
+- CSP headers prevent inline script execution
+- HTML in user inputs is escaped, not rendered
+
+### Assessment: GOOD
+
+**Positive:**
+- Pydantic on all API inputs is FastAPI best practice
+- Server-side + client-side sanitization (defense in depth)
+- CSP header is well-configured: `script-src 'self'`, `object-src 'none'`, `base-uri 'self'`
+- XSS test scenarios defined in requirements
+
+**MINOR RISK m-05: No SQL injection prevention explicitly documented**  
+- **Finding:** While SQLAlchemy ORM with parameterized queries is the default, the architecture does not explicitly state a prohibition on raw SQL or string interpolation in queries.
+- **Recommendation:** Add an explicit coding guideline: no raw SQL with string interpolation; all raw queries must use parameterized `text()` with bind parameters.
+
+---
+
+## 5. SECRETS MANAGEMENT (F-ENV-01)
+
+### Design Summary
+- `.env.example` documents all environment variables with `<secret>` placeholders
+- Secrets never in Git repo (`.gitignore` includes `.env`)
+- Missing secret env var then app fails to start with clear error (F-ENV-01 test scenario 3)
+- Secrets: POSTGRES_PASSWORD, LEOCRM_SECRET_KEY, SMTP_PASS, MAIL_ENCRYPTION_KEY, S3_SECRET_KEY, AI_API_KEY
+- Pydantic Settings for env var loading (config.py)
+
+### Assessment: ADEQUATE for v1 with gaps
+
+**MAJOR RISK M-04: No secret rotation policy**  
+- **Finding:** No rotation procedure is defined for any secret (LEOCRM_SECRET_KEY, MAIL_ENCRYPTION_KEY, POSTGRES_PASSWORD, SMTP_PASS). F-ENV-01 only covers initial setup, not lifecycle.
+- **Impact:** If a secret is compromised, there is no documented procedure to rotate it. MAIL_ENCRYPTION_KEY rotation is especially critical — changing it without a re-encryption plan would make existing encrypted mail credentials unreadable.
+- **Recommendation:** 
+  1. Document rotation procedures for each secret in admin guide
+  2. For MAIL_ENCRYPTION_KEY: implement key versioning (store key_id with encrypted data, support old + new key during rotation)
+  3. For LEOCRM_SECRET_KEY: document that rotation invalidates all sessions (acceptable)
+  4. For POSTGRES_PASSWORD: document procedure (change password, update env, restart)
+
+**MINOR RISK m-06: .env file approach for production**  
+- **Finding:** Docker Compose uses `env_file: .env` for all services including production on Coolify. This means secrets are stored in a plaintext file on the server.
+- **Impact:** If the host filesystem is compromised, all secrets are readable. Docker env vars are also visible via `docker inspect`.
+- **Recommendation:** For production on Coolify, use Coolify's secret/environment variable management (injects as container env vars without a file on disk). The `.env` file approach is fine for dev only. Document this split in the deployment guide.
+
+---
+
+## 6. DATA MIGRATION RISK (F-MIG-01)
+
+### Design Summary
+- F-MIG-01: CSV import with field mapping, per-row error reporting, auto-company-detection for contact imports
+- No legacy system data migration (no ETL from external CRM systems)
+- No schema migration risk (greenfield project with Alembic)
+
+### Assessment: LOW RISK — properly scoped
+
+**Positive:**
+- CSV import is well-defined with field mapping and error handling
+- No complex legacy migration in v1 (correct scope decision)
+- Alembic for schema migrations is standard and reliable
+
+**MAJOR RISK M-05: CSV import has no file size limit or row count validation**  
+- **Finding:** F-MIG-01 test scenario imports 50 companies. No mention of maximum file size, maximum row count, or memory protection for large CSV files. A 500MB CSV with 1M rows could cause OOM or timeout.
+- **Impact:** Denial of service via large CSV upload; potential memory exhaustion.
+- **Recommendation:** 
+  1. Define max upload size (e.g., 10MB for CSV)
+  2. Process CSV in streaming mode (not loading entire file into memory)
+  3. Add row count limit (e.g., 50,000 rows per import)
+  4. Run import as background job (ARQ) for files >1000 rows
+
+---
+
+## 7. BACKUP/RESTORE (F-INFRA-02)
+
+### Design Summary
+- `pg_dump` daily cron job to backup volume or S3
+- Storage volume backup (files)
+- Restore documented in `docs/admin-guide.md`
+- Backup failure triggers alert to admin
+
+### Assessment: MAJOR RISK — inadequate for multi-tenant production
+
+**MAJOR RISK M-06: Backup strategy insufficient for multi-tenant PostgreSQL**  
+- **Finding:** The backup design has multiple gaps:
+  1. **No backup encryption:** `pg_dump` output is plaintext. Tenant data (companies, contacts, emails) is stored unencrypted in the backup volume/S3.
+  2. **No retention policy:** No definition of how many backups to keep (7 days? 30 days?). Unlimited backups cause storage exhaustion; too few cause data loss.
+  3. **No tested restore procedure:** F-INFRA-02 acceptance criterion says "Restore-Dokumentation vorhanden" but there is no test scenario that verifies an actual restore works.
+  4. **No point-in-time recovery:** Only daily `pg_dump` snapshots. If a tenant accidentally deletes data at 14:00 and notices at 17:00, all data created between 00:00 and 14:00 that day is lost.
+  5. **Multi-tenant restore granularity:** `pg_dump` is all-or-nothing. If one tenant needs restore, all tenants are affected. No mention of tenant-level export/restore.
+  6. **Redis not backed up:** Session data is in Redis with TTL=8h. Redis is not included in backup strategy. If Redis is lost, all active sessions are invalidated (users must re-login). This is acceptable but should be documented.
+- **Recommendation:**
+  1. Encrypt pg_dump output (gpg or S3 SSE-KMS)
+  2. Define retention: 7 daily + 4 weekly + 12 monthly
+  3. Add a restore test to the test suite (backup, restore, verify row count)
+  4. Enable PostgreSQL WAL archiving for point-in-time recovery (PITR)
+  5. Document that restore is all-tenant; consider tenant-level CSV export as a quick-recovery alternative
+  6. Document Redis session loss behavior (acceptable: users re-login)
+
+---
+
+## 8. PLUGIN SECURITY (T03 Plugin Framework)
+
+### Design Summary
+- Built-in plugins only (no dynamic external loading in v1) — ADR-03
+- Plugin manifest schema (Pydantic)
+- Lifecycle hooks: install/activate/deactivate/uninstall
+- Plugin DB migration runner with `plugin_migrations` tracking
+- Migration validator checks `tenant_id` on all plugin tables
+- Service Container DI: plugins receive db, cache, event_bus, storage, notifications
+- Event Bus integration: plugins register/unregister event listeners
+
+### Assessment: MODERATE RISK — tenant isolation enforced, but no permission scoping
+
+**MAJOR RISK M-07: No plugin API permission scoping**  
+- **Finding:** Plugins receive injected services (db, cache, event_bus, storage, notifications) but there is no permission model restricting what a plugin can do. A plugin with access to the `db` session can query any table within the current tenant context. There is no "plugin A can only read companies, plugin B can only write to its own tables" model.
+- **Impact:** A malicious or buggy built-in plugin could access/modify data from other modules within the same tenant. Since all v1 plugins are built-in (shipped with code), this is lower risk, but the architecture should define the permission model for when external plugins are added post-MVP.
+- **Recommendation:**
+  1. For v1: document that plugins are trusted (built-in only) and have full tenant-scoped access
+  2. For post-MVP: define plugin permission scopes in the manifest (e.g., `permissions: ["companies:read", "contacts:write"]`)
+  3. Add a test: plugin cannot access data from a different tenant (already covered by tenant_id validator)
+
+**MINOR RISK m-07: Plugin event bus has no namespacing**  
+- **Finding:** Plugins register event listeners on a shared event bus. There is no mention of event namespacing to prevent event name collisions between plugins.
+- **Recommendation:** Use prefixed event names (e.g., `dms.file.uploaded`, `calendar.event.created`) to avoid collisions.
+
+**MINOR RISK m-08: Plugin uninstall with data removal has no confirmation audit**  
+- **Finding:** `DELETE /api/v1/plugins/{name}?remove_data=true` drops plugin tables. The architecture does not mention that this destructive action is logged in the audit log.
+- **Recommendation:** Log plugin uninstall with data removal to `audit_log` with actor, timestamp, plugin name, and table list.
+
+---
+
+## 9. DEPENDENCY RISKS
+
+### Design Summary
+- **Backend:** FastAPI, SQLAlchemy, Pydantic, ARQ, Redis-py, asyncpg/psycopg
+- **Frontend:** React 18, TanStack Query v5, Vite, Tailwind CSS
+- **Database:** PostgreSQL 16-alpine
+- **Cache/Queue:** Redis 7-alpine
+- **Document editing:** OnlyOffice Document Server
+
+### Assessment: LOW-MODERATE RISK
+
+**OnlyOffice `:latest` tag**  
+- **Finding:** Docker Compose uses `onlyoffice/documentserver:latest`. This tag is mutable and can introduce breaking changes or security vulnerabilities without notice.
+- **Impact:** Unpredictable updates; potential breaking changes; supply chain risk.
+- **Recommendation:** Pin to a specific version tag (e.g., `onlyoffice/documentserver:8.2.2`). Update deliberately after testing.
+
+**Other dependency notes:**
+- FastAPI, React 18, PostgreSQL 16, Redis 7 are all current stable major versions with active security maintenance
+- No known critical CVEs in these major versions as of 2026-06
+- **Recommendation:** Pin all dependencies in `requirements.txt` / `package.json` with exact versions or minimum patches. Add `pip-audit` and `npm audit` to CI pipeline.
+- **Recommendation:** Use `postgres:16-alpine` and `redis:7-alpine` (already specified — good). Pin minor versions for reproducibility.
+
+---
+
+## 10. RATE LIMITING
+
+### Assessment: MAJOR RISK — explicitly excluded from v1
+
+**Finding:** Non-Goals section 18: "Kein zentrales Rate-Limiting in v1." This means:
+- `POST /api/v1/auth/login` — no rate limit (brute-force possible, see M-01)
+- `POST /api/v1/auth/password-reset/request` — no rate limit (email bombing possible)
+- All API endpoints — no rate limit (DoS via excessive requests)
+- API tokens (post-MVP) — no rate limit per token
+
+**Impact:**
+- Auth endpoints are brute-force vulnerable (mitigated partially by bcrypt cost=12, but not for distributed attacks)
+- Password reset endpoint can be abused to send unlimited emails (SMTP abuse, email bombing)
+- General API abuse (data scraping, DoS)
+
+**Recommendation:**
+- Implement **auth-scoped rate limiting** (not general rate limiting) before Phase 3:
+  - Login: 10 attempts per email per 15 min (Redis counter)
+  - Password reset: 3 requests per email per hour
+  - This is minimal effort and high security value
+- General API rate limiting can remain post-MVP if the app is internal-only, but document the decision
+
+---
+
+## 11. CORS
+
+**MAJOR RISK M-08: CORS configuration not specified**  
+- **Finding:** The frontend is served on port 80 (Nginx) and the API on port 8000 (FastAPI). In production, they may share a domain (reverse proxy) or be on separate ports. The architecture does not specify CORS headers.
+- **Impact:** If frontend and API are on different origins (e.g., dev environment: `localhost:80` to `localhost:8000`), the browser will block requests without proper CORS headers. If CORS is set to wildcard, credentials (cookies) will not work.
+- **Recommendation:**
+  - In production: serve frontend + API behind the same reverse proxy (same origin, no CORS needed)
+  - In development: configure FastAPI CORS middleware with `allow_origins=["http://localhost:80"]`, `allow_credentials=True`, `allow_methods=["*"]`, `allow_headers=["*"]`
+  - Never use `allow_origins=["*"]` with `allow_credentials=True` (browser rejects this)
+  - Document CORS configuration in architecture.md
+

+
+## 12. DOCKER/COMPOSE SECURITY
+
+### Findings
+
+| Issue | Severity | Detail |
+|-------|----------|--------|
+| No non-root user | Minor | All containers run as root by default. Add `user:` directive or use images with non-root users. |
+| No `cap_drop: ALL` | Minor | Containers retain all Linux capabilities. Drop all and add only needed ones. |
+| No read-only filesystem | Minor | Add `read_only: true` with `tmpfs` for writable paths. |
+| Redis without auth | Major | `redis:7-alpine` has no `requirepass` or ACL configured. Any container on the network can access Redis. |
+| OnlyOffice `:latest` | Minor | Mutable tag; pin to specific version. |
+| All ports exposed | Minor | `ports: ["8000:8000"]`, `["80:80"]`, `["8080:80"]` expose to host. In production, use internal network + reverse proxy only. |
+| No health checks on all services | Minor | Only `backend` has a healthcheck. Add for `postgres`, `redis`, `worker`. |
+| No resource limits | Minor | No `mem_limit`, `cpus` limits. A runaway process can consume all host resources. |
+
+**Recommendation for Redis auth:**
+- Add `REDIS_PASSWORD` env var
+- Configure Redis with `requirepass` or use ACL users
+- Update `REDIS_URL` to include password: `redis://:<password>@redis:6379/0`
+
+---
+
+## 13. FILE UPLOADS
+
+### Finding
+DMS plugin (T05) handles file uploads via `POST /api/v1/dms/files/upload (multipart)`. The architecture does not specify:
+- Maximum file size limit
+- Allowed file types / MIME type validation
+- File content verification (magic bytes, not just extension)
+- Malware / virus scanning
+- Filename sanitization (path traversal prevention)
+
+### Assessment: MAJOR RISK (deferred to plugin implementation)
+- **Impact:** Path traversal via malicious filenames, disk exhaustion via large files, stored XSS via uploaded HTML/SVG files, potential malware storage.
+- **Recommendation:** Define upload security in T05 task specification:
+  1. Max file size: 50MB (configurable)
+  2. Allowed MIME types whitelist (exclude `text/html`, `image/svg+xml`, `application/javascript`)
+  3. Filename sanitization: strip path components, use UUID-based storage names
+  4. Store files outside web root (already handled by storage service)
+  5. Post-MVP: ClamAV integration for malware scanning
+
+---
+
+## 14. LOGGING SENSITIVE DATA
+
+### Assessment: GOOD
+- Structured JSON logs (F-INFRA-03): timestamp, level, event, method, path, status, duration, tenant_id, user_id
+- No password, token, or secret values in log format
+- Log level configurable via `LOG_LEVEL` env var
+- **Recommendation:** Add explicit log sanitization in the logging middleware: filter out `password`, `new_password`, `token`, `Authorization` header fields from request body logging if request body is ever logged.
+
+---
+
+## 15. DATA PERSISTENCE AND DATA LOSS RISK
+
+### Assessment: MODERATE RISK
+- Soft-delete with `deleted_at` column — good for accidental deletion recovery
+- DSGVO hard-delete with `deletion_log` — good for compliance
+- `deletion_log` mentioned in architecture but table schema not fully defined in the reviewed sections
+- **Risk:** Soft-deleted data is still in the database. If a tenant requests GDPR deletion, the hard-delete must also remove soft-deleted records.
+- **Recommendation:** Verify `deletion_log` table schema includes: tenant_id, entity_type, entity_id, deleted_by, deleted_at, data_summary (for audit).
+

+## SUMMARY TABLE
+
+| # | Risk | Severity | Domain | Action Before Phase 3? |
+|---|------|----------|--------|----------------------|
+| M-01 | No brute-force protection on auth | Major | Auth | YES — add Redis-based attempt counter |
+| M-02 | RLS claimed but ORM-only filtering | Major | Multi-Tenant | YES — add DB-level RLS as defense-in-depth |
+| M-03 | ARQ worker tenant context undefined | Major | Multi-Tenant | YES — define in architecture |
+| M-04 | No secret rotation policy | Major | Secrets | NO — document before deployment |
+| M-05 | CSV import no size/row limit | Major | Migration | NO — add in T05/T07 implementation |
+| M-06 | Backup insufficient for multi-tenant | Major | Backup | NO — resolve before deployment |
+| M-07 | No plugin API permission scoping | Major | Plugins | NO — acceptable for v1 (built-in only) |
+| M-08 | CORS not specified | Major | Network | YES — configure and document |
+| m-01 | LEOCRM_SECRET_KEY purpose/rotation undefined | Minor | Secrets | NO |
+| m-02 | No 2FA in v1 | Minor | Auth | NO (post-MVP) |
+| m-03 | Tenant switch membership validation | Minor | Multi-Tenant | YES — add test case |
+| m-04 | CSRF token stored but unused | Minor | CSRF | NO — clarify architecture |
+| m-05 | No SQL injection prevention guideline | Minor | Validation | NO — add coding guideline |
+| m-06 | .env file for production | Minor | Secrets | NO — use Coolify env management |
+| m-07 | Plugin event bus no namespacing | Minor | Plugins | NO |
+| m-08 | Plugin uninstall no audit log | Minor | Plugins | NO |
+
+---
+
+## TOP 3 RISKS
+
+1. **M-02: RLS gap** — Architecture claims PostgreSQL RLS but implements only ORM-level tenant filtering. Raw SQL, worker jobs, or filter bypass bugs can leak cross-tenant data. **Must add DB-level RLS policies as defense-in-depth before implementation.**
+
+2. **M-01: No brute-force protection** — Auth endpoints (login, password reset) have no rate limiting, lockout, or failed-attempt tracking. Combined with M-08 (no CORS config), the attack surface for credential attacks is significant. **Must add minimal Redis-based auth rate limiting before Phase 3.**
+
+3. **M-06: Backup strategy inadequate** — No encryption, no retention policy, no tested restore, no PITR for multi-tenant PostgreSQL. Data loss risk for production tenants. **Must resolve before deployment phase.**
+
+---
+
+## RECOMMENDATION FOR PHASE 3 START
+
+**APPROVED_WITH_CONCERNS — Phase 3 may start after addressing the 3 pre-implementation items:**
+
+1. **M-02:** Add PostgreSQL RLS policy definitions to architecture.md (defense-in-depth alongside ORM filtering)
+2. **M-01 + Rate Limiting:** Add auth-scoped rate limiting (login attempt counter + password reset throttle) to T01 task specification
+3. **M-08:** Add CORS configuration to architecture.md (same-origin in prod, explicit origins in dev)
+
+Additionally, update T01 task to include:
+- ARQ worker tenant context propagation (M-03)
+- Tenant switch membership validation test (m-03)
+- Redis auth configuration (Docker Compose)
+
+The remaining major risks (M-04, M-05, M-06, M-07) can be addressed during implementation or before deployment.
