feat: redesign Fristenrechner — cards, no tabs, inline calculation

Replace the Schnell/Wizard tab layout with a unified flow:
1. Proceeding type selection via compact clickable cards grouped
   by jurisdiction + category (UPC Hauptverfahren, im Verfahren,
   Rechtsbehelfe, Deutsche Patentverfahren)
2. Vertical deadline rule list for the selected type showing name,
   duration, rule code, and acting party
3. Inline expansion on click with date picker, auto-calculated due
   date (via selected_rule_ids API), holiday/weekend adjustment
   note, and save-to-case option

Old DeadlineCalculator.tsx and DeadlineWizard.tsx are no longer
imported but kept for reference.

+# KanzlAI-mGMT MVP Audit
+
+**Date:** 2026-03-28
+**Auditor:** athena (consultant)
+**Scope:** Full-stack audit of KanzlAI-mGMT — Go backend, Next.js frontend, Supabase database, deployment, security, UX, competitive positioning.
+**Codebase:** ~16,500 lines across ~60 source files, built 2026-03-25 in a single session with parallel workers.
+
+---
+
+## Executive Summary
+
+KanzlAI-mGMT is an impressive MVP built in ~2 hours. It covers the core Kanzleimanagement primitives: cases, deadlines, appointments, parties, documents, notes, dashboard, CalDAV sync, and AI-powered deadline extraction. The architecture is sound — clean separation between Go API and Next.js frontend, proper multi-tenant design with Supabase Auth, parameterized SQL throughout.
+
+However, the speed of construction shows. There are **critical security gaps** that must be fixed before any external user touches this. The frontend has good bones but lacks the polish and completeness a lawyer would expect. And the feature gap vs. established competitors (RA-MICRO, ADVOWARE, AnNoText, Actaport) is enormous — particularly around beA integration, billing/RVG, and document generation, which are table-stakes for German law firms.
+
+**Bottom line:** Fix the security issues, add error recovery and multi-tenant auth verification, then decide whether to pursue the Kanzleimanagement market (massive feature gap) or pivot back to the UPC niche (where you had a genuine competitive advantage).
+
+---
+
+## 1. Critical Issues (Fix Immediately)
+
+### 1.1 Tenant Isolation Bypass in TenantResolver
+**File:** `backend/internal/auth/tenant_resolver.go:37-42`
+
+When the `X-Tenant-ID` header is provided, the TenantResolver parses it and sets it in context **without verifying the user has access to that tenant**. Any authenticated user can access any tenant's data by setting this header.
+
+```go
+if header := r.Header.Get("X-Tenant-ID"); header != "" {
+    parsed, err := uuid.Parse(header)
+    // ... sets tenantID = parsed — NO ACCESS CHECK
+}
+```
+
+Compare with `helpers.go:32-44` where `resolveTenant()` correctly verifies access via `user_tenants` — but this function is unused in the middleware path. The TenantResolver middleware is what actually runs for all scoped routes.
+
+**Impact:** Complete tenant data isolation breach. User A can read/modify/delete User B's cases, deadlines, appointments, documents.
+
+**Fix:** Add `user_tenants` lookup in TenantResolver when X-Tenant-ID is provided, same as `resolveTenant()` does.
+
+### 1.2 Duplicate Tenant Resolution Logic
+**Files:** `backend/internal/auth/tenant_resolver.go` and `backend/internal/handlers/helpers.go:25-57`
+
+Two independent implementations of tenant resolution exist. The middleware (`TenantResolver`) is used for the scoped routes. The handler-level `resolveTenant()` function exists in helpers.go. The auth middleware in `middleware.go:39-47` also resolves a tenant into context. This triple-resolution creates confusion and the security bug above.
+
+**Fix:** Consolidate to a single path. Remove the handler-level `resolveTenant()` and the auth middleware's tenant resolution. Let TenantResolver be the single source of truth, but make it verify access.
+
+### 1.3 CalDAV Credentials Stored in Plaintext
+**File:** `backend/internal/services/caldav_service.go:29-35`
+
+CalDAV username and password are stored as plain JSON in the `tenants.settings` column:
+```go
+type CalDAVConfig struct {
+    URL      string `json:"url"`
+    Username string `json:"username"`
+    Password string `json:"password"`
+    ...
+}
+```
+
+Combined with the tenant isolation bypass above, any authenticated user can read any tenant's CalDAV credentials.
+
+**Fix:** Encrypt CalDAV credentials at rest (e.g., using `pgcrypto` or application-level encryption). At minimum, never return the password in API responses.
+
+### 1.4 No CORS Configuration
+**File:** `backend/internal/router/router.go`, `backend/cmd/server/main.go`
+
+There is zero CORS handling anywhere in the backend. The frontend uses Next.js rewrites to proxy `/api/` to the backend, which works in production. But:
+- If anyone accesses the backend directly (different origin), there's no CORS protection.
+- No `X-Frame-Options`, `X-Content-Type-Options`, or other security headers are set.
+
+**Fix:** Add CORS middleware restricting to the frontend origin. Add standard security headers.
+
+### 1.5 Internal Error Messages Leaked to Clients
+**Files:** Multiple handlers (e.g., `cases.go:44`, `cases.go:73`, `appointments.go`)
+
+```go
+writeError(w, http.StatusInternalServerError, err.Error())
+```
+
+Internal error messages (including SQL errors, connection errors, etc.) are sent directly to the client. This leaks implementation details.
+
+**Fix:** Log the full error server-side, return a generic message to the client.
+
+### 1.6 Race Condition in HolidayService Cache
+**File:** `backend/internal/services/holidays.go`
+
+The `HolidayService` uses a `map[int][]Holiday` cache without any mutex protection. Concurrent requests (e.g., multiple deadline calculations) will cause a data race. The Go race detector would flag this.
+
+**Fix:** Add `sync.RWMutex` to HolidayService.
+
+### 1.7 Rate Limiter Trivially Bypassable
+**File:** `backend/internal/middleware/ratelimit.go:78-79`
+
+```go
+ip := r.Header.Get("X-Forwarded-For")
+if ip == "" { ip = r.RemoteAddr }
+```
+
+Rate limiting keys off `X-Forwarded-For`, which any client can spoof. An attacker can bypass AI endpoint rate limits by rotating this header.
+
+**Fix:** Only trust `X-Forwarded-For` from configured reverse proxy IPs, or use `r.RemoteAddr` exclusively behind a trusted proxy.
+
+---
+
+## 2. Important Gaps (Fix Before Showing to Anyone)
+
+### 2.1 No Input Validation Beyond "Required Fields"
+**Files:** All handlers
+
+Input validation is minimal — typically just checking if required fields are empty:
+```go
+if input.CaseNumber == "" || input.Title == "" {
+    writeError(w, http.StatusBadRequest, "case_number and title are required")
+}
+```
+
+Missing:
+- Length limits on text fields (could store megabytes in a title field)
+- Status value validation (accepts any string for status fields)
+- Date format validation
+- Case type validation against allowed values
+- SQL-safe string validation (although parameterized queries protect against injection)
+
+### 2.2 No Pagination Defaults on Most List Endpoints
+**File:** `backend/internal/services/case_service.go:57-63`
+
+`CaseService.List` has sane defaults (limit=20, max=100). But other list endpoints (`appointments`, `deadlines`, `notes`, `parties`, `case_events`) have no pagination at all — they return all records for a tenant/case. As data grows, these become performance problems.
+
+### 2.3 Dashboard Page is Entirely Client-Side
+**File:** `frontend/src/app/(app)/dashboard/page.tsx`
+
+The entire dashboard is a `"use client"` component that fetches data via API. This means:
+- No SSR benefit — the page is blank until JS loads and API responds
+- SEO doesn't matter for a SaaS app, but initial load time does
+- The skeleton is nice but adds 200-400ms of perceived latency
+
+For an internal tool this is acceptable, but for a commercial product it should use server components for the initial render.
+
+### 2.4 Frontend Auth Uses `getSession()` Instead of `getUser()`
+**File:** `frontend/src/lib/api.ts:10-12`
+
+```typescript
+const { data: { session } } = await supabase.auth.getSession();
+```
+
+`getSession()` reads from local storage without server verification. If a session is expired or revoked server-side, the frontend will still try to use it until the backend rejects it. The middleware correctly uses `getUser()` (which validates server-side), but the API client does not.
+
+### 2.5 Missing Error Recovery in Frontend
+Throughout the frontend, API errors are handled with basic error states, but there's no:
+- Retry logic for transient failures
+- Token refresh on 401 responses
+- Optimistic UI rollback on mutation failures
+- Offline detection
+
+### 2.6 Missing `Content-Disposition` Header Sanitization
+**File:** `backend/internal/handlers/documents.go:133`
+
+```go
+w.Header().Set("Content-Disposition", fmt.Sprintf(`attachment; filename="%s"`, title))
+```
+
+The `title` (which comes from user input) is inserted directly into the header. A filename containing `"` or newlines could be used for response header injection.
+
+**Fix:** Sanitize the filename — strip or encode special characters.
+
+### 2.7 No Graceful Shutdown
+**File:** `backend/cmd/server/main.go:42`
+
+```go
+http.ListenAndServe(":"+cfg.Port, handler)
+```
+
+No signal handling or graceful shutdown. When the process receives SIGTERM (e.g., during deployment), in-flight requests are dropped, CalDAV sync operations may be interrupted mid-write, and database connections are not cleanly closed.
+
+### 2.8 Database Connection Pool — search_path is Session-Level
+**File:** `backend/internal/db/connection.go:17`
+
+```go
+db.Exec("SET search_path TO kanzlai, public")
+```
+
+`SET search_path` is session-level in PostgreSQL. With connection pooling (`MaxOpenConns: 25`), this SET runs once on the initial connection. If a connection is recycled or a new one opened from the pool, it may not have the kanzlai search_path. This could cause queries to silently hit the wrong schema.
+
+**Fix:** Use `SET LOCAL search_path` in a transaction, or set it at the database/role level, or qualify all table references with the schema name.
+
+### 2.9 go.sum Missing from Dockerfile
+**File:** `backend/Dockerfile:4`
+
+```dockerfile
+COPY go.mod ./
+RUN go mod download
+```
+
+Only `go.mod` is copied, not `go.sum`. This means the build isn't reproducible and doesn't verify checksums. Should be `COPY go.mod go.sum ./`.
+
+### 2.10 German Umlaut Typos Throughout Frontend
+**Files:** Multiple frontend components
+
+German strings use ASCII approximations instead of proper characters:
+- `login/page.tsx`: "Zurueck" instead of "Zurück"
+- `cases/[id]/layout.tsx`: "Anhaengig" instead of "Anhängig"
+- `cases/[id]/fristen/page.tsx`: "Ueberfaellig" instead of "Überfällig"
+- `termine/page.tsx`: "Uberblick" instead of "Überblick"
+
+A German lawyer would notice this immediately. It signals "this was built by a machine, not tested by a human."
+
+### 2.11 Silent Error Swallowing in Event Creation
+**File:** `backend/internal/services/case_service.go:260-266`
+
+```go
+func createEvent(ctx context.Context, db *sqlx.DB, ...) {
+    db.ExecContext(ctx, /* ... */)  // Error completely ignored
+}
+```
+
+Case events (audit trail) silently fail to create. The calling functions don't check the return. This means you could have cases with no events and no way to know why.
+
+### 2.12 Missing Error Boundaries in Frontend
+No React error boundaries are implemented. If any component throws, the entire page crashes with a white screen. For a law firm tool where data integrity matters, this is unacceptable.
+
+### 2.13 No RLS Policies Defined at Database Level
+Multi-tenant isolation relies entirely on `WHERE tenant_id = $X` clauses in Go code. If any query forgets this clause, data leaks across tenants. There are no PostgreSQL RLS policies as a safety net.
+
+**Fix:** Enable RLS on all tenant-scoped tables and create policies tied to `auth.uid()` via `user_tenants`.
+
+---
+
+## 3. Architecture Assessment
+
+### 3.1 What's Good
+
+- **Clean monorepo structure** — `backend/` and `frontend/` are clearly separated. Each has its own Dockerfile. The Makefile provides unified commands.
+- **Go backend is well-organized** — `cmd/server/`, `internal/{auth,config,db,handlers,middleware,models,router,services}` follows Go best practices.
+- **Handler/Service separation** — handlers do HTTP concerns (parse request, write response), services do business logic. This is correct.
+- **Parameterized SQL everywhere** — no string concatenation in queries. All user input goes through `$N` placeholders.
+- **Multi-tenant design** — `tenant_id` on every row, context-based tenant resolution, RLS at the database level.
+- **Smart use of Go 1.22+ routing** — method+path patterns like `GET /api/cases/{id}` eliminate the need for a third-party router.
+- **CalDAV sync is genuinely impressive** — bidirectional sync with conflict resolution, etag tracking, background polling per-tenant. This is a differentiator.
+- **Deadline calculator** — ported from youpc.org with holiday awareness. Legally important and hard to build.
+- **Frontend routing structure** — German URL paths (`/fristen`, `/termine`, `/einstellungen`), nested case detail routes with layout.tsx for shared chrome. Proper use of App Router patterns.
+
+### 3.2 Structural Concerns
+
+- **No database migrations** — the schema was apparently created via SQL scripts run manually. There's a `seed/demo_data.sql` but no migration system. For a production system, this is unsustainable.
+- **No CI/CD pipeline** — no `.github/workflows/`, `.gitea/`, or any CI configuration. Tests run locally but not automatically.
+- **No API versioning** — all routes are at `/api/`. Adding breaking changes will break clients.
+- **Services take raw `*sqlx.DB`** — no transaction support across service boundaries. Creating a case + event is not atomic (if the event insert fails, the case still exists).
+- **Models are just struct definitions** — no validation methods, no constructor functions. Validation is scattered across handlers.
+
+### 3.3 Data Model
+
+Based on the seed data and model files, the schema is reasonable:
+- `tenants`, `user_tenants` (multi-tenancy)
+- `cases`, `parties` (case management)
+- `deadlines`, `appointments` (time management)
+- `documents`, `case_events`, `notes` (supporting data)
+- `proceeding_types`, `deadline_rules`, `holidays` (reference data)
+
+**Missing indexes likely needed:**
+- `deadlines(tenant_id, status, due_date)` — for dashboard queries
+- `appointments(tenant_id, start_at)` — for calendar queries
+- `case_events(case_id, created_at)` — for event feeds
+- `cases(tenant_id, status)` — for filtered lists
+
+**Missing constraints:**
+- No CHECK constraint on status values (cases, deadlines, appointments)
+- No UNIQUE constraint on `case_number` per tenant
+- No foreign key from `notes` to the parent entity (if polymorphic)
+
+---
+
+## 4. Security Assessment
+
+### 4.1 Authentication
+- **JWT validation is correct** — algorithm check (HMAC only), expiry check, sub claim extraction. Using `golang-jwt/v5`.
+- **Supabase Auth on frontend** — proper cookie-based session with server-side verification in middleware.
+- **No refresh token rotation** — the API client uses `getSession()` which may serve stale tokens.
+
+### 4.2 Authorization
+- **Critical: Tenant isolation bypass** (see 1.1)
+- **No role-based access control** — `user_tenants` has a `role` column but it's never checked. Any member can do anything.
+- **No resource-level permissions** — any user in a tenant can delete any case, document, etc.
+
+### 4.3 Input Validation
+- **SQL injection: Protected** — all queries use parameterized placeholders.
+- **XSS: Partially protected** — React auto-escapes, but the API returns raw strings that could contain HTML. The `Content-Disposition` header is vulnerable (see 2.6).
+- **File upload: Partially protected** — `MaxBytesReader` limits to 50MB, but no file type validation (could upload .exe, .html with scripts, etc.).
+- **Rate limiting: AI endpoints only** — the rest of the API has no rate limiting. Login/register go through Supabase (which has its own limits), but all CRUD endpoints are unlimited.
+
+### 4.4 Secrets
+- **No hardcoded secrets** — all via environment variables. Good.
+- **CalDAV credentials in plaintext** — see 1.3.
+- **Supabase service key in backend** — necessary for storage, but this key has full DB access. Should be scoped.
+
+---
+
+## 5. Testing Assessment
+
+### 5.1 Backend Tests (15 files)
+- **Integration test** — sets up real DB connection, creates JWT, tests full HTTP flow. Excellent pattern but requires DATABASE_URL (skips otherwise).
+- **Handler tests** — mock-based unit tests for most handlers. Test JSON parsing, error responses, basic happy paths.
+- **Service tests** — deadline calculator has solid date arithmetic tests. Holiday service tested. CalDAV service tested with mocks. AI service tested with mocked HTTP.
+- **Middleware tests** — rate limiter tested.
+- **Auth tests** — tenant resolver tested.
+
+### 5.2 Frontend Tests (4 files)
+- `api.test.ts` — tests the API client
+- `DeadlineTrafficLights.test.tsx` — component test
+- `CaseOverviewGrid.test.tsx` — component test
+- `LoginPage.test.tsx` — auth page test
+
+### 5.3 What's Missing
+- **No E2E tests** — no Playwright/Cypress. Critical for a law firm app where correctness matters.
+- **No contract tests** — frontend and backend are tested independently. A schema change could break the frontend without any test catching it.
+- **Deadline calculation edge cases** — needs tests for year boundaries, leap years, holidays falling on weekends, multiple consecutive holidays.
+- **Multi-tenant security tests** — no test verifying that User A can't access Tenant B's data. This is the most important test to add.
+- **Frontend test coverage is thin** — 4 tests for ~30 components. The dashboard, all forms, navigation, error states are untested.
+- **No load testing** — unknown how the system behaves under concurrent users.
+
+---
+
+## 6. UX Assessment
+
+### 6.1 What Works
+- **Dashboard is strong** — traffic light deadline indicators, upcoming timeline, case overview, quick actions. A lawyer can see what matters at a glance.
+- **German localization** — UI is in German with proper legal terminology (Akten, Fristen, Termine, Parteien).
+- **Mobile responsive** — sidebar collapses to hamburger menu, layout uses responsive grids.
+- **Loading states** — skeleton screens on dashboard, not just spinners.
+- **Breadcrumbs** — navigation trail on all pages.
+- **Deadline calculator** — unique feature that provides real value for UPC litigation.
+
+### 6.2 What a Lawyer Would Stumble On
+1. **No onboarding flow** — after registration, user has no tenant, no cases. The app shows empty states but doesn't guide the user to create a tenant or import data.
+2. **No search** — there's no global search. A lawyer with 100+ cases needs to find things fast.
+3. **No keyboard shortcuts** — power users (lawyers are keyboard-heavy) have no shortcuts.
+4. **Sidebar mixes languages** — "Akten" (German) vs "AI Analyse" (English). Should be consistent.
+5. **No notifications** — overdue deadlines don't trigger any alert beyond the dashboard color. No email alerts, no push notifications.
+6. **No print view** — lawyers need to print deadline lists, case summaries. No print stylesheet.
+7. **No bulk operations** — can't mark multiple deadlines as complete, can't bulk-assign parties.
+8. **Document upload has no preview** — uploaded PDFs can't be viewed inline.
+9. **AI features require manual trigger** — AI summary and deadline extraction are manual. Should auto-trigger on document upload.
+10. **No activity log per user** — no audit trail of who changed what. Critical for law firm compliance.
+
+---
+
+## 7. Deployment Assessment
+
+### 7.1 Docker Setup
+- **Multi-stage builds** — both Dockerfiles use builder pattern. Good.
+- **Backend is minimal** — Alpine + static binary + ca-certificates. ~15MB image.
+- **Frontend** — Bun for deps/build, Node for runtime (standalone output). Reasonable.
+- **Missing:** go.sum not copied in backend Dockerfile (see 2.9).
+- **Missing:** No docker-compose.yml for local development.
+- **Missing:** No health check in Dockerfile (`HEALTHCHECK` instruction).
+
+### 7.2 Environment Handling
+- **Config validates required vars** — `DATABASE_URL` and `SUPABASE_JWT_SECRET` are checked at startup.
+- **Supabase URL/keys not validated** — if missing, features silently fail or crash at runtime.
+- **No .env.example** — new developers don't know what env vars are needed.
+
+### 7.3 Reliability
+- **No graceful shutdown** (see 2.7)
+- **No readiness/liveness probes** — `/health` exists but only checks DB connectivity. No readiness distinction.
+- **CalDAV sync runs in-process** — if the sync goroutine panics, it takes down the API server.
+- **No structured error recovery** — panics in handlers will crash the process (no recovery middleware).
+
+---
+
+## 8. Competitive Analysis
+
+### 8.1 The Market
+
+German Kanzleisoftware is a mature, crowded market:
+
+| Tool | Type | Price | Key Strength |
+|------|------|-------|-------------|
+| **RA-MICRO** | Desktop + Cloud | ~100-200 EUR/user/mo | Market leader, 30+ years, full beA integration |
+| **ADVOWARE** | Desktop + Cloud | from 20 EUR/mo | Budget-friendly, strong for small firms |
+| **AnNoText** (Wolters Kluwer) | Desktop + Cloud | Custom pricing | Enterprise, AI document analysis, DictNow |
+| **Actaport** | Cloud-native | from 79.80 EUR/mo | Modern UI, Mandantenportal, integrated Office |
+| **Haufe Advolux** | Cloud | Custom | User-friendly, full-featured |
+| **Renostar Legal Cloud** | Cloud | Custom | Browser-based, no installation |
+
+### 8.2 Table-Stakes Features KanzlAI is Missing
+
+These are **mandatory** for any German Kanzleisoftware to be taken seriously:
+
+1. **beA Integration** — since 2022, German lawyers must use the electronic court mailbox (besonderes elektronisches Anwaltspostfach). No Kanzleisoftware sells without it. This is a **massive** implementation effort (KSW-Schnittstelle from BRAK).
+
+2. **RVG Billing (Gebührenrechner)** — automated fee calculation per RVG (Rechtsanwaltsvergütungsgesetz). Every competitor has this built-in. Without it, lawyers can't bill clients.
+
+3. **Document Generation** — templates for Schriftsätze, Klageschriften, Mahnbescheide with auto-populated case data. Usually integrated with Word.
+
+4. **Accounting (FiBu)** — client trust accounts (Fremdgeld), DATEV export, tax-relevant bookkeeping. Legal requirement.
+
+5. **Conflict Check (Kollisionsprüfung)** — check if the firm has a conflict of interest before taking a case. Legally required (§ 43a BRAO).
+
+6. **Dictation System** — voice-to-text for lawyers. RA-MICRO has DictaNet, AnNoText has DictNow.
+
+### 8.3 Where KanzlAI Could Differentiate
+
+Despite the feature gap, KanzlAI has some advantages:
+
+1. **AI-native** — competitors are bolting AI onto 20-year-old software. KanzlAI has Claude API integration from day one. The deadline extraction from PDFs is genuinely useful.
+2. **UPC specialization** — the deadline calculator with UPC Rules of Procedure knowledge is unique. No competitor has deep UPC litigation support.
+3. **CalDAV sync** — bidirectional sync with external calendars is not common in German Kanzleisoftware.
+4. **Modern tech stack** — React + Go + Supabase vs. the .NET/Java/Desktop world of RA-MICRO et al.
+5. **Multi-tenant from day 1** — designed for SaaS, not converted from desktop software.
+
+### 8.4 Strategic Recommendation
+
+**Don't compete head-on with RA-MICRO.** The feature gap is 10+ person-years of work. Instead:
+
+**Option A: UPC Niche Tool** — Pivot back to UPC patent litigation. Build the best deadline calculator, case tracker, and AI-powered brief analysis tool for UPC practitioners. There are ~1000 UPC practitioners in Europe who need specialized tooling that RA-MICRO doesn't provide. Charge 200-500 EUR/mo.
+
+**Option B: AI-First Legal Assistant** — Don't call it "Kanzleimanagement." Position as an AI assistant that reads court documents, extracts deadlines, and syncs to the lawyer's existing Kanzleisoftware via CalDAV/iCal. This sidesteps the feature gap entirely.
+
+**Option C: Full Kanzleisoftware** — If you pursue this, beA integration is the first priority, then RVG billing. Without these two, no German lawyer will switch.
+
+---
+
+## 9. Strengths (What's Good, Keep Doing It)
+
+1. **Architecture is solid** — the Go + Next.js + Supabase stack is well-chosen. Clean separation of concerns.
+2. **SQL is safe** — parameterized queries throughout. No injection vectors.
+3. **Multi-tenant design** — tenant_id scoping with RLS is the right approach.
+4. **CalDAV implementation** — genuinely impressive for an MVP. Bidirectional sync with conflict resolution.
+5. **Deadline calculator** — ported from youpc.org with holiday awareness. Real domain value.
+6. **AI integration** — Claude API with tool use for structured extraction. Clean implementation.
+7. **Dashboard UX** — traffic lights, timeline, quick actions. Lawyers will get this immediately.
+8. **German-first** — proper legal terminology, German date formats, localized UI.
+9. **Test foundation** — 15 backend test files with integration tests. Good starting point.
+10. **Docker builds are lean** — multi-stage, Alpine-based, standalone Next.js output.

+# Design: Dashboard Redesign + Detail Pages
+
+**Task:** t-kz-060
+**Author:** cronus (inventor)
+**Date:** 2026-03-25
+**Status:** Design proposal
+
+---
+
+## Problem Statement
+
+The current dashboard is a read-only status board. Cards show counts but don't link anywhere. Timeline items are inert. Quick actions navigate to list pages rather than creation flows. There are no detail pages for individual events, deadlines, or appointments. Notes don't exist as a first-class entity. Case detail tabs use local state instead of URL segments, breaking deep linking and back navigation.
+
+## Design Principles
+
+1. **Everything clickable goes somewhere** — no dead-end UI
+2. **Breadcrumb navigation** — always know where you are, one click to go back
+3. **German labels throughout** — consistent with existing convention
+4. **Mobile responsive** — sidebar collapses, cards stack, touch targets >= 44px
+5. **Information density over whitespace** — law firm users want data, not decoration
+6. **URL-driven state** — tabs, filters, and views reflected in the URL for deep linking
+
+---
+
+## Part 1: Dashboard Redesign
+
+### 1.1 Traffic Light Cards → Click-to-Filter
+
+**Current:** Three cards (Ueberfaellig / Diese Woche / Im Zeitplan) show counts. `onFilter` prop exists but is never wired up in `dashboard/page.tsx`.
+
+**Proposed:**
+
+Clicking a traffic light card navigates to `/fristen?status={filter}`:
+
+| Card | Navigation Target |
+|------|------------------|
+| Ueberfaellig (red) | `/fristen?status=overdue` |
+| Diese Woche (amber) | `/fristen?status=this_week` |
+| Im Zeitplan (green) | `/fristen?status=ok` |
+
+**Implementation:**
+- Replace `onFilter` callback with `next/link` navigation using `href`
+- `DeadlineTrafficLights` becomes a pure link-based component (no callback needed)
+- `/fristen` page reads `searchParams.status` and pre-applies the filter
+- The DeadlineList component already supports status filtering — just needs to read from URL
+
+**Changes:**
+- `DeadlineTrafficLights.tsx`: Replace `<button onClick>` with `<Link href="/fristen?status=...">`
+- `fristen/page.tsx`: Read `searchParams` and pass as initial filter to DeadlineList
+- `DeadlineList.tsx`: Accept `initialStatus` prop from URL params
+
+### 1.2 Case Overview Grid → Click-to-Filter
+
+**Current:** Three static metrics (Aktive Akten / Neu / Abgeschlossen). No links.
+
+**Proposed:**
+
+| Card | Navigation Target |
+|------|------------------|
+| Aktive Akten | `/cases?status=active` |
+| Neu (Monat) | `/cases?status=active&since=month` |
+| Abgeschlossen | `/cases?status=closed` |
+
+**Implementation:**
+- Wrap each metric row in `<Link>` to `/cases` with appropriate query params
+- Cases list page already has filtering — needs to read URL params on mount
+- Add visual hover state (arrow icon on hover, background highlight)
+
+**Changes:**
+- `CaseOverviewGrid.tsx`: Each row becomes a `<Link>` with hover arrow
+- `cases/page.tsx`: Read `searchParams` for initial filter state
+
+### 1.3 Timeline Items → Click-to-Navigate
+
+**Current:** Timeline entries show deadline/appointment info but are not clickable. No link to the parent case or the item itself.
+
+**Proposed:**
+
+Each timeline entry becomes a clickable row:
+
+- **Deadline entries**: Click navigates to `/fristen/{id}` (new deadline detail page)
+- **Appointment entries**: Click navigates to `/termine/{id}` (new appointment detail page)
+- **Case reference** (Az. / case_number): Secondary click target linking to `/cases/{case_id}`
+
+**Visual changes:**
+- Add `cursor-pointer` and hover state (`hover:bg-neutral-100` transition)
+- Add a small chevron-right icon on the right edge
+- Case number becomes a subtle underlined link (click stops propagation)
+
+**Data changes:**
+- `UpcomingDeadline` needs `case_id` field (currently missing from the dashboard query — the backend model has it but the SQL join doesn't select it)
+- `UpcomingAppointment` already has `case_id`
+
+**Backend change:**
+- `dashboard_service.go` line 112: Add `d.case_id` to the upcoming deadlines SELECT
+- `DashboardService.UpcomingDeadline` struct: Add `CaseID uuid.UUID` field
+- Frontend `UpcomingDeadline` type: Already has `case_id` (it's in types.ts but the backend doesn't send it)
+
+### 1.4 Quick Actions → Proper Navigation
+
+**Current:** "Frist eintragen" goes to `/fristen` (list page), not a creation flow. "CalDAV Sync" goes to `/einstellungen`.
+
+**Proposed:**
+
+| Action | Current Target | New Target |
+|--------|---------------|------------|
+| Neue Akte | `/cases/new` | `/cases/new` (keep) |
+| Frist eintragen | `/fristen` | `/fristen/neu` (new creation page) |
+| Neuer Termin | (missing) | `/termine/neu` (new creation page) |
+| AI Analyse | `/ai/extract` | `/ai/extract` (keep) |
+
+Replace "CalDAV Sync" with "Neuer Termin" — CalDAV sync is a settings function, not a daily quick action. Creating an appointment is something a secretary does multiple times per day.
+
+**Changes:**
+- `QuickActions.tsx`: Update hrefs, swap CalDAV for appointment creation
+- Create `/fristen/neu/page.tsx` — standalone deadline creation form (select case, fill fields)
+- Create `/termine/neu/page.tsx` — standalone appointment creation form
+
+### 1.5 AI Summary Card → Refresh Button
+
+**Current:** Rule-based summary text, no refresh mechanism. Card regenerates on page load but not on demand.
+
+**Proposed:**
+- Add a small refresh icon button (RefreshCw) in the card header, next to "KI-Zusammenfassung"
+- Clicking it calls `refetch()` on the dashboard query (passed as prop)
+- Show a brief spinning animation during refetch
+- If/when real AI summarization is wired up, this button triggers `POST /api/ai/summarize-dashboard` (future endpoint)
+
+**Changes:**
+- `AISummaryCard.tsx`: Accept `onRefresh` prop, add button with spinning state
+- `dashboard/page.tsx`: Pass `refetch` to AISummaryCard
+
+### 1.6 Dashboard Layout: Add Recent Activity Section
+
+**Current:** The backend returns `recent_activity` (last 10 case events) but the frontend ignores it entirely.
+
+**Proposed:**
+- Add a "Letzte Aktivitaet" section below the timeline, full width
+- Shows the 10 most recent case events in a compact list
+- Each row: event icon (by type) | title | case number (linked) | relative time
+- Clicking a row navigates to the case event detail page `/cases/{case_id}/ereignisse/{event_id}`
+
+**Changes:**
+- New component: `RecentActivityList.tsx` in `components/dashboard/`
+- `dashboard/page.tsx`: Add section below the main grid
+- Add `RecentActivity` type to `types.ts` (needs `case_id` and `event_id` fields from backend)
+- Backend: Add `case_id` and `id` to the recent activity query
+
+---
+
+## Part 2: New Pages
+
+### 2.1 Deadline Detail Page — `/fristen/{id}`
+
+**Route:** `src/app/(app)/fristen/[id]/page.tsx`
+
+**Layout:**

+
+**Data requirements:**
+- `GET /api/deadlines/{id}` — new endpoint returning full deadline with case info

+
+**Sections:**
+1. **Header**: Status badge (Offen/Erledigt/Ueberfaellig), title, "Erledigen" action button
+2. **Due date**: Large, with relative time ("in 3 Tagen" / "vor 2 Tagen ueberfaellig")
+3. **Context panel**: Parent case (linked), source (manual/calculated/caldav), rule reference, original vs adjusted date
+4. **Notes section**: Free-text notes (existing `notes` field on deadline), inline edit
+5. **Activity log**: Timeline of changes to this deadline (future: from case_events filtered by deadline)
+
+**Backend additions:**
+- `GET /api/deadlines/{id}` — new handler returning single deadline with case join

++---------------------------------------------------------+
+```
+
+**Data requirements:**

+- Notes: Uses new `notes` table (see Part 3)
+
+**Backend additions:**
+- `GET /api/appointments/{id}` — new handler

+
+### 2.3 Case Event Detail Page — `/cases/{id}/ereignisse/{eventId}`
+
+**Route:** `src/app/(app)/cases/[id]/ereignisse/[eventId]/page.tsx`
+

+
+**Data requirements:**
+- `GET /api/case-events/{id}` — new endpoint
+- Notes: Uses new `notes` table
+
+**Backend additions:**
+- New handler: `case_events.go` with `Get` method
+- New service method: `CaseEventService.GetByID`
+- Or extend existing case handler to include event fetching
+
+### 2.4 Standalone Deadline Creation — `/fristen/neu`
+
+**Route:** `src/app/(app)/fristen/neu/page.tsx`
+
+**Layout:**
+
+```
+Breadcrumb: Fristen > Neue Frist
++---------------------------------------------------------+
+| Neue Frist anlegen                                       |
++---------------------------------------------------------+
+| Akte*:        [Dropdown: Aktenauswahl]                  |
+| Bezeichnung*: [________________________]                |

++---------------------------------------------------------+
+|                              [Abbrechen]  [Frist anlegen]|
++---------------------------------------------------------+
+```
+
+Reuses existing deadline creation logic but as a standalone page rather than requiring the user to first navigate to a case. Case is selected via dropdown.
+
+### 2.5 Standalone Appointment Creation — `/termine/neu`
+
+**Route:** `src/app/(app)/termine/neu/page.tsx`
+
+Same pattern as deadline creation. Reuses AppointmentModal fields but as a full page form. Appointment can optionally be linked to a case.
+
+### 2.6 Case Detail Tabs → URL Segments
+
+**Current:** Tabs use `useState<TabKey>` — no URL change, no deep linking, no browser back.
+
+**Proposed route structure:**
+
+```
+/cases/{id}              → redirects to /cases/{id}/verlauf
+/cases/{id}/verlauf      → Timeline tab
+/cases/{id}/fristen      → Deadlines tab
+/cases/{id}/dokumente    → Documents tab
+/cases/{id}/parteien     → Parties tab
+/cases/{id}/notizen      → Notes tab (new)
+```
+
+**Implementation approach:**
+
+Use Next.js nested layouts with a shared layout for the case header + tab bar:
+
+```
+src/app/(app)/cases/[id]/
+  layout.tsx              # Case header + tab navigation
+  page.tsx                # Redirect to ./verlauf
+  verlauf/page.tsx        # Timeline
+  fristen/page.tsx        # Deadlines
+  dokumente/page.tsx      # Documents
+  parteien/page.tsx       # Parties
+  notizen/page.tsx        # Notes (new)
+```
+
+The `layout.tsx` fetches case data and renders the header + tab bar. Each child page renders its tab content. The active tab is determined by the current pathname.
+
+**Benefits:**
+- Deep linking: `/cases/abc123/fristen` opens directly to the deadlines tab
+- Browser back button works between tabs
+- Each tab can have its own loading state
+- Bookmarkable
+
+---
+
+## Part 3: Notes System
+
+### 3.1 Data Model
+
+Notes are a polymorphic entity — they can be attached to cases, deadlines, appointments, or case events.
+
+**New table: `kanzlai.notes`**
+
+```sql
+CREATE TABLE kanzlai.notes (
+    id          UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    tenant_id   UUID NOT NULL REFERENCES kanzlai.tenants(id),
+
+    -- Polymorphic parent reference (exactly one must be set)
+    case_id         UUID REFERENCES kanzlai.cases(id) ON DELETE CASCADE,
+    deadline_id     UUID REFERENCES kanzlai.deadlines(id) ON DELETE CASCADE,
+    appointment_id  UUID REFERENCES kanzlai.appointments(id) ON DELETE CASCADE,
+    case_event_id   UUID REFERENCES kanzlai.case_events(id) ON DELETE CASCADE,
+
+    content     TEXT NOT NULL,
+    created_by  UUID,           -- auth.users reference
+    created_at  TIMESTAMPTZ NOT NULL DEFAULT now(),
+    updated_at  TIMESTAMPTZ NOT NULL DEFAULT now(),
+
+    -- Ensure exactly one parent is set
+    CONSTRAINT notes_single_parent CHECK (
+        (CASE WHEN case_id IS NOT NULL THEN 1 ELSE 0 END +
+         CASE WHEN deadline_id IS NOT NULL THEN 1 ELSE 0 END +
+         CASE WHEN appointment_id IS NOT NULL THEN 1 ELSE 0 END +
+         CASE WHEN case_event_id IS NOT NULL THEN 1 ELSE 0 END) = 1
+    )
+);
+
+-- Indexes for efficient lookup by parent
+CREATE INDEX idx_notes_case ON kanzlai.notes(tenant_id, case_id) WHERE case_id IS NOT NULL;
+CREATE INDEX idx_notes_deadline ON kanzlai.notes(tenant_id, deadline_id) WHERE deadline_id IS NOT NULL;
+CREATE INDEX idx_notes_appointment ON kanzlai.notes(tenant_id, appointment_id) WHERE appointment_id IS NOT NULL;
+CREATE INDEX idx_notes_case_event ON kanzlai.notes(tenant_id, case_event_id) WHERE case_event_id IS NOT NULL;
+
+-- RLS
+ALTER TABLE kanzlai.notes ENABLE ROW LEVEL SECURITY;
+CREATE POLICY notes_tenant_isolation ON kanzlai.notes
+    USING (tenant_id IN (
+        SELECT tenant_id FROM kanzlai.user_tenants WHERE user_id = auth.uid()
+    ));
+```
+
+### 3.2 Why Polymorphic Table vs Separate Tables
+
+**Considered alternatives:**
+
+1. **Separate notes per entity** (case_notes, deadline_notes, etc.) — More tables, duplicated logic, harder to search across all notes.
+2. **Generic `entity_type` + `entity_id` pattern** — Loses FK constraints, can't cascade delete, harder to query with joins.
+3. **Polymorphic with nullable FKs** (chosen) — FK constraints maintained, cascade deletes work, partial indexes keep queries fast, single service/handler. The CHECK constraint ensures data integrity.
+
+### 3.3 Backend Model & API
+
+**Go model:**
+
+```go
+type Note struct {
+    ID            uuid.UUID  `db:"id" json:"id"`
+    TenantID      uuid.UUID  `db:"tenant_id" json:"tenant_id"`
+    CaseID        *uuid.UUID `db:"case_id" json:"case_id,omitempty"`
+    DeadlineID    *uuid.UUID `db:"deadline_id" json:"deadline_id,omitempty"`
+    AppointmentID *uuid.UUID `db:"appointment_id" json:"appointment_id,omitempty"`
+    CaseEventID   *uuid.UUID `db:"case_event_id" json:"case_event_id,omitempty"`
+    Content       string     `db:"content" json:"content"`
+    CreatedBy     *uuid.UUID `db:"created_by" json:"created_by,omitempty"`
+    CreatedAt     time.Time  `db:"created_at" json:"created_at"`
+    UpdatedAt     time.Time  `db:"updated_at" json:"updated_at"`
+}
+```
+
+**API endpoints:**
+
+```
+GET    /api/notes?case_id={id}            # List notes for a case
+GET    /api/notes?deadline_id={id}        # List notes for a deadline
+GET    /api/notes?appointment_id={id}     # List notes for an appointment
+GET    /api/notes?case_event_id={id}      # List notes for a case event
+POST   /api/notes                         # Create note (body includes parent ID)
+PUT    /api/notes/{id}                    # Update note content
+DELETE /api/notes/{id}                    # Delete note
+```
+
+Single endpoint with query parameter filtering — simpler than nested routes, works uniformly across all parent types.
+
+**Service methods:**
+
+```go
+type NoteService struct { db *sqlx.DB }
+
+func (s *NoteService) ListByParent(ctx, tenantID, parentType, parentID) ([]Note, error)
+func (s *NoteService) Create(ctx, tenantID, note) (*Note, error)
+func (s *NoteService) Update(ctx, tenantID, noteID, content) (*Note, error)
+func (s *NoteService) Delete(ctx, tenantID, noteID) error
+```
+
+### 3.4 Notes UI Component
+
+Reusable `<NotesList>` component used on every detail page:
+
+```
++------------------------------------------------------------+
+| Notizen                                            [+ Neu] |
++------------------------------------------------------------+
+| m@kanzlei.de · 25. Mär 2026, 14:30                [X][E] |
+| Fristverlängerung beim Gericht beantragt.                  |
++------------------------------------------------------------+
+| m@kanzlei.de · 24. Mär 2026, 10:15                [X][E] |
+| Mandant telefonisch über Sachstand informiert.             |
++------------------------------------------------------------+
+```
+
+**Props:**
+```typescript
+interface NotesListProps {
+  parentType: "case" | "deadline" | "appointment" | "case_event";
+  parentId: string;
+}
+```
+
+**Features:**
+- Fetches notes via `GET /api/notes?{parentType}_id={parentId}`
+- "Neu" button opens inline textarea (not a modal — faster for quick notes)
+- Each note shows: author, timestamp, content, edit/delete buttons
+- Edit is inline (textarea replaces content)
+- Optimistic updates via react-query mutation + invalidation
+- Empty state: "Keine Notizen vorhanden. Klicken Sie +, um eine Notiz hinzuzufügen."
+
+### 3.5 Migration from `deadlines.notes` Field
+
+The existing `deadlines.notes` text field should be migrated:
+1. For each deadline with a non-null `notes` value, create a corresponding row in the `notes` table with `deadline_id` set
+2. Drop the `deadlines.notes` column after migration
+3. This can be a one-time SQL migration script
+
+---
+
+## Part 4: Breadcrumb Navigation
+
+### 4.1 Breadcrumb Component
+
+New shared component: `src/components/layout/Breadcrumb.tsx`
+
+```typescript
+interface BreadcrumbItem {
+  label: string;
+  href?: string;  // omit for current page (last item)
+}
+
+function Breadcrumb({ items }: { items: BreadcrumbItem[] }) {
+  // Renders: Home > Parent > Current
+  // Each item with href is a Link, last item is plain text
+}
+```
+
+**Placement:** At the top of every page, inside the main content area (not in the layout — different pages have different breadcrumbs).
+
+### 4.2 Breadcrumb Patterns
+
+| Page | Breadcrumb |
+|------|-----------|
+| Dashboard | Dashboard |
+| Fristen | Dashboard > Fristen |
+| Fristen Detail | Dashboard > Fristen > {title} |
+| Fristen Neu | Dashboard > Fristen > Neue Frist |
+| Termine | Dashboard > Termine |
+| Termine Detail | Dashboard > Termine > {title} |
+| Termine Neu | Dashboard > Termine > Neuer Termin |
+| Akten | Dashboard > Akten |

+## Part 5: Summary of Backend Changes
+
+### New Endpoints
+
+| Method | Path | Handler | Purpose |

+
+### Modified Endpoints
+
+| Endpoint | Change |
+|----------|--------|
+| `GET /api/dashboard` | Add `case_id`, `id` to recent_activity; add `case_id` to upcoming_deadlines query |

+| `src/components/layout/Breadcrumb.tsx` | Reusable breadcrumb |
+| `src/components/notes/NotesList.tsx` | Reusable notes list + inline creation |
+| `src/components/dashboard/RecentActivityList.tsx` | Recent activity feed |
+
+### Modified Files
+
+| File | Change |
+|------|--------|
+| `src/components/dashboard/DeadlineTrafficLights.tsx` | Buttons → Links with navigation |
+| `src/components/dashboard/CaseOverviewGrid.tsx` | Static metrics → clickable links |
+| `src/components/dashboard/UpcomingTimeline.tsx` | Items → clickable with navigation |
+| `src/components/dashboard/AISummaryCard.tsx` | Add refresh button |
+| `src/components/dashboard/QuickActions.tsx` | Fix targets, swap CalDAV for Termin |
+| `src/app/(app)/dashboard/page.tsx` | Wire navigation, add RecentActivity section |
+| `src/app/(app)/fristen/page.tsx` | Read URL params for initial filter |
+| `src/app/(app)/cases/page.tsx` | Read URL params for initial filter |
+| `src/app/(app)/cases/[id]/page.tsx` | Refactor into layout + nested routes |
+| `src/lib/types.ts` | Add Note, RecentActivity types; update UpcomingDeadline |
+
+### Types to Add
+
+```typescript
+export interface Note {
+  id: string;
+  tenant_id: string;
+  case_id?: string;
+  deadline_id?: string;
+  appointment_id?: string;
+  case_event_id?: string;
+  content: string;
+  created_by?: string;
+  created_at: string;
+  updated_at: string;
+}
+
+export interface RecentActivity {
+  id: string;
+  event_type?: string;
+  title: string;
+  case_id: string;
+  case_number: string;
+  event_date?: string;
+  created_at: string;
+}
+```
+
+---
+
+## Part 7: Implementation Plan
+
+Recommended order for a coder to implement:
+
+### Phase A: Backend Foundation (can be done in parallel)
+1. Create `notes` table migration + model + service + handler
+2. Add `GET /api/deadlines/{id}` endpoint
+3. Add `GET /api/appointments/{id}` endpoint
+4. Add `GET /api/case-events/{id}` endpoint
+5. Fix dashboard query to include `case_id` in upcoming deadlines and recent activity
+
+### Phase B: Frontend — Dashboard Interactivity
+1. Create `Breadcrumb` component
+2. Make traffic light cards clickable (Links)
+3. Make case overview grid clickable (Links)
+4. Make timeline items clickable (Links)
+5. Fix quick actions (swap CalDAV for Termin, update hrefs)
+6. Add refresh button to AI Summary card
+7. Add RecentActivityList component + wire to dashboard
+
+### Phase C: Frontend — New Detail Pages
+1. Deadline detail page (`/fristen/[id]`)
+2. Appointment detail page (`/termine/[id]`)
+3. Case event detail page (`/cases/[id]/ereignisse/[eventId]`)
+4. Standalone deadline creation (`/fristen/neu`)
+5. Standalone appointment creation (`/termine/neu`)
+
+### Phase D: Frontend — Case Detail Refactor
+1. Extract case header + tabs into layout.tsx
+2. Create sub-route pages (verlauf, fristen, dokumente, parteien)
+3. Add notes tab
+4. Wire `NotesList` component into all detail pages
+
+### Phase E: Polish
+1. URL filter params on `/fristen` and `/cases` pages
+2. Breadcrumbs on all pages
+3. Mobile responsive testing
+4. Migration of existing `deadlines.notes` data
+
+---
+
+## Appendix: What This Design Does NOT Cover
+
+- Real AI-powered summary (currently rule-based — kept as-is with refresh button)
+- Notification system (toast-based alerts for approaching deadlines)
+- Audit log / change history per entity
+- Batch operations (mark multiple deadlines complete)
+- Print views
+
+These are separate features that can be designed independently.
