+ * RBAC data-access matrix — dev system
+ *
+ * Verifies that role-based access control is enforced at the network level
+ * (tRPC response payload) against the running dev server with real seed data.
+ *
+ * Unlike rbac-permissions.spec.ts (which checks UI visibility), these tests
+ * call tRPC procedures directly via fetch() inside the browser context and
+ * assert on HTTP status + tRPC error codes in the response body.
+ *
+ * All tests use pre-authenticated storage states — no signIn() calls, no
+ * auth rate limiter pressure. 3 logins total per suite run (from globalSetup).
+ *
+ * Tested procedures and their audience classes (docs/route-access-matrix.md):
+ *
+ *   user.list            → admin-only     (adminProcedure)
+ *   allocation.listView  → planning-read  (planningReadProcedure → VIEW_PLANNING)
+ *   resource.listSummaries → resource-overview (resourceOverviewProcedure)
+ *   user.listAssignable  → manager-write  (managerProcedure → ADMIN or MANAGER)
+ *
+ * Expected access matrix:
+ *
+ *   Procedure               ADMIN  MANAGER  VIEWER
+ *   user.list               ✓      FORBIDDEN FORBIDDEN

+# Developer Runbook
+
+**Stand:** 2026-04-01  
+**Zweck:** Vollständige Referenz für lokales Setup, täglichen Betrieb und Recovery-Szenarien.
+
+---
+
+## Erstmaliges Setup (Fresh Checkout)
+
+```bash
+# 1. Repo klonen
+git clone <url> capakraken && cd capakraken
+
+# 2. Root-Env anlegen (NEXTAUTH_SECRET ist Pflicht, kein Default)
+cp .env.example .env
+# .env öffnen und NEXTAUTH_SECRET setzen (min. 32 zufällige Zeichen)
+# Beispiel: openssl rand -hex 32
+
+# 3. Docker-Stack starten (Postgres + Redis + App)
+docker compose --profile full up -d
+
+# 4. Warten bis gesund, dann Seed ausführen
+docker compose exec app pnpm --filter @capakraken/db exec prisma db seed
+```
+
+Der App-Container führt beim Start automatisch `prisma migrate deploy` + `prisma generate` aus (via `tooling/docker/app-dev-start.sh`).
+
+---
+
+## Täglicher Start
+
+```bash
+docker compose --profile full up -d
+```
+
+Nur Postgres + Redis (ohne App — z. B. für `pnpm run dev` auf dem Host):
+
+```bash
+docker compose up -d postgres redis
+pnpm run dev
+```
+
+---
+
+## Env-Var-Strategie
+
+### Warum Docker-interne URLs hardcodiert sind
+
+`docker-compose.yml` setzt `DATABASE_URL` und `REDIS_URL` als **explizite Literal-Strings** — kein `${VAR:-default}`.
+
+Hintergrund: Docker Compose löst Shell-Substitutionen (`${VAR:-fallback}`) gegen das **Host-Environment** auf, bevor der Container startet. Hatte der Host ein `DATABASE_URL=postgresql://localhost:5433/...` gesetzt (z. B. für lokale Entwicklung ohne Docker), landete dieser Wert im Container — wo `localhost` der Container selbst ist, nicht der Host. Das brach die DB-Verbindung.
+
+Explizite Literal-Werte im `environment:`-Block haben höchste Priorität und können nicht durch Host-Env-Vars überschrieben werden.
+
+**Regel:** Docker-interne Service-DNS-Namen (`postgres`, `redis`) dürfen nie in `${...}`-Ausdrücken stehen.
+
+### E2E_TEST_MODE — warum doppelt gesetzt
+
+Das Flag muss an **zwei Stellen** stehen:
+
+| Ort | Wann aktiv |
+|---|---|
+| `docker-compose.yml` → `environment:` | Wenn die App im Docker-Container läuft |
+| `apps/web/.env.local` | Wenn die App lokal per `pnpm run dev` läuft |
+
+Next.js lädt `.env.local` via Volume-Mount. Docker Compose liest nur seinen eigenen `environment:`-Block. Beide Quellen sind nötig — es gibt keine gemeinsame "eine Stelle".
+
+### Geheime Werte (API-Keys, SMTP, etc.)
+
+Secrets werden **nicht** in `docker-compose.yml` gesetzt (versionierte Datei). Sie gehören in:
+
+- **Lokale Entwicklung:** root `.env` (gitignored)
+- **Docker-Container:** Env-Block in `docker-compose.yml` ist für nicht-geheime Werte. Geheime Werte kommen via `env_file: .env` in docker-compose (`.env` ist gitignored und wird nie committed).
+
+Benötigte Env-Vars für KI-Funktionen:
+
+```
+AZURE_OPENAI_API_KEY=<Azure OpenAI API Key>
+GEMINI_API_KEY=<Google Gemini API Key>
+```
+
+---
+
+## DB-Migration-Strategie
+
+### Normale Entwicklung: `migrate dev`
+
+```bash
+node scripts/prisma-with-env.mjs migrate dev --name <beschreibender_name>
+```
+
+- Erzeugt eine neue Migration unter `packages/db/prisma/migrations/`
+- Wendet sie auf die lokale DB an
+- Aktualisiert den Prisma Client
+- **Immer committen** — die Migration-Datei ist Teil des Repos
+
+### Production / Docker: `migrate deploy`
+
+```bash
+node scripts/prisma-with-env.mjs migrate deploy
+```
+
+- Wendet nur bereits erstellte Migrationen an (kein Schema-Diff)
+- Idempotent: Bereits angewandte Migrationen werden übersprungen
+
+### NIEMALS `db push` in einer Migration-verwalteten Umgebung
+
+`db push` schreibt Schema-Änderungen direkt in die DB **ohne** einen `_prisma_migrations`-Eintrag. Wird danach `migrate deploy` ausgeführt, scheitert es mit **P3005** ("database schema is not empty").
+
+### Recovery P3005 — Bestehende DB ohne Migrations-History
+
+Symptom: `prisma migrate deploy` meldet P3005.  
+Ursache: DB wurde initial per `db push` aufgesetzt.
+
+Lösung:
+
+```bash
+# Welche Migrationen existieren?
+ls packages/db/prisma/migrations/
+
+# Für jede Migration, die bereits in der DB ist, ausführen:
+node scripts/prisma-with-env.mjs migrate resolve --applied <migration_folder_name>
+# Beispiel:
+# node scripts/prisma-with-env.mjs migrate resolve --applied 20260401000000_active_sessions
+
+# Danach: migrate deploy läuft normal durch
+node scripts/prisma-with-env.mjs migrate deploy
+```
+
+`migrate resolve --applied` erstellt den `_prisma_migrations`-Eintrag ohne SQL auszuführen — es teilt Prisma mit, dass diese Migration bereits angewandt wurde.
+
+---
+
+## Container-Neustart nach Code-Änderungen
+
+| Änderung | Aktion |
+|---|---|
+| TypeScript-Quellcode | Kein Restart nötig (Hot Reload via Turborepo) |
+| `schema.prisma` geändert | `docker compose restart app` (führt `prisma generate` aus) |
+| Neue Migration erstellt | `docker compose restart app` (führt `migrate deploy` aus) |
+| `docker-compose.yml` geändert | `docker compose --profile full up -d` (recreate) |
+| Node-Module aktualisiert | `docker compose build app && docker compose --profile full up -d` |
+
+### Nach `--force-recreate` oder Image-Rebuild
+
+Der App-Container benötigt beim ersten Start nach einem Rebuild Zeit für `pnpm install`. Logs prüfen:
+
+```bash
+docker compose logs -f app
+```
+
+Warten bis: `✓ Ready on http://0.0.0.0:3100`
+
+---
+
+## Kompletter DB-Reset
+
+```bash
+# Stack stoppen
+docker compose --profile full down
+
+# Named Volume löschen (verliert alle Daten!)
+docker volume rm capakraken_pgdata
+
+# Neu starten — Container führt beim Start Migrationen aus
+docker compose --profile full up -d
+
+# Seed ausführen
+docker compose exec app pnpm --filter @capakraken/db exec prisma db seed
+```
+
+---
+
+## E2E-Tests gegen den Dev-Server
+
+```bash
+cd apps/web
+
+# Alle Dev-System-Tests
+pnpm exec playwright test --config=playwright.dev.config.ts
+
+# Nur RBAC-Tests
+pnpm exec playwright test e2e/dev-system/rbac-permissions.spec.ts --config=playwright.dev.config.ts
+pnpm exec playwright test e2e/dev-system/rbac-data-access.spec.ts --config=playwright.dev.config.ts
+```
+
+Voraussetzung: Dev-Server läuft auf `localhost:3100` (Docker oder `pnpm run dev`).  
+`E2E_TEST_MODE=true` muss in der laufenden Instanz gesetzt sein (s. o.).
+
+---
+
+## Häufige Probleme
+
+| Problem | Ursache | Fix |
+|---|---|---|
+| P3005 bei `migrate deploy` | DB per `db push` initialisiert | `migrate resolve --applied` für jede bestehende Migration |
+| P1001 "Can't reach database" | `DATABASE_URL` zeigt auf falschen Host | Im Container ist `localhost` der Container selbst; Docker-interne URL (`postgres:5432`) verwenden |
+| tRPC 401 nach E2E-Tests | E2E-Sessions haben echte Sessions aus `active_sessions` verdrängt | `E2E_TEST_MODE=true` setzen (registriert keine `active_sessions`) |
+| Auth-Rate-Limit erschöpft | Zu viele Logins in Tests | `globalSetup` nutzt StorageState; direkte `signIn()`-Calls in Tests minimieren |
+| Timeline leer nach Tests | E2E-Session hat Admin-Session aus `active_sessions` gekickt | Einloggen + E2E_TEST_MODE prüfen |

+
+## Plan: In-Review-Tickets verifizieren und in main integrieren
+
+### Anforderungsanalyse
+
+8 Tickets sind `in-review`. Ziel: jeden Ticket-Scope im Code verifizieren, Gitea-Kommentar
+mit Bewertung (✅ akzeptiert / ⚠️ Nachbesserung nötig) hinterlassen, dann alle offenen
+Changes in einem sauberen Commit auf `main` integrieren.
+
+**Umfang der Verifikation pro Ticket:**
+- Code-Artefakte im Repo prüfen (Dateien, Tests)
+- Quality-Gates (tsc, test:unit) müssen grün sein
+- Akzeptanzkriterien aus dem Ticket-Body abgleichen
+- Gitea-Kommentar: Strukturiertes Urteil mit Befunden
+
+**Integration-Strategie:**
+- Alle ungestagten Änderungen (`git status`) gehören zu den Tickets #20, #22, #25, #26
+- Ein einziger Commit auf `main` mit klarer Commit-Message
+- plan.md und docs/ mitcommiten
+
+### Betroffene Pakete & Dateien
+
+| Paket | Dateien | Art der Änderung |
+|-------|---------|-----------------|
+| `apps/web` | `next.config.ts`, `src/app/layout.tsx`, `src/middleware.ts`, `src/middleware.test.ts`, `src/app/api/perf/route.ts`, `src/app/api/perf/route.test.ts`, `src/components/security/MfaSetup.test.ts`, `e2e/dev-system/rbac-data-access.spec.ts`, `e2e/dev-system/helpers.ts` | Verifikation + commit |
+| `packages/api` | `src/__tests__/ssrf-guard.test.ts`, `src/__tests__/webhook-procedure-support.test.ts` | Verifikation + commit |
+| root | `package.json`, `docker-compose.yml`, `docs/developer-runbook.md`, `plan.md` | Verifikation + commit |
+
+### Task-Liste (atomare Schritte in Reihenfolge)
+
+**Phase 1 — Verifikation & Kommentierung (sequenziell, ein Ticket nach dem anderen)**
+
+- [ ] **V-1:** Ticket #19 (MFA-QR) — Code-Check: `MfaSetup.tsx` + `MfaSetup.test.ts`; Urteil auf Gitea posten
+- [ ] **V-2:** Ticket #20 (Webhook SSRF) — Code-Check: `ssrf-guard.ts` + `ssrf-guard.test.ts` + `webhook-procedure-support.test.ts`; Urteil posten
+- [ ] **V-3:** Ticket #21 (/api/perf) — Code-Check: `route.ts` + `route.test.ts`; Urteil posten
+- [ ] **V-4:** Ticket #22 (CSP) — Code-Check: `middleware.ts` + `middleware.test.ts` + `next.config.ts` + `layout.tsx`; Urteil posten
+- [ ] **V-5:** Ticket #23 (Active-Session-Registry) — Code-Check: Session-Guard-Middleware, Auth-Flow; Urteil posten
+- [ ] **V-6:** Ticket #24 (Docker reproducibility) — Code-Check: `docker-compose.yml`, Dockerfile.dev; Urteil posten
+- [ ] **V-7:** Ticket #25 (Env/Migration-Strategie) — Code-Check: `docker-compose.yml`, `docs/developer-runbook.md`; Urteil posten
+- [ ] **V-8:** Ticket #26 (RBAC E2E-Tests) — Code-Check: `rbac-data-access.spec.ts`; Urteil posten
+
+**Phase 2 — Quality Gates**
+
+- [ ] **Q-1:** `pnpm --filter @capakraken/web exec tsc --noEmit` — keine Fehler
+- [ ] **Q-2:** `pnpm --filter @capakraken/api test:unit` — alle Tests grün
+- [ ] **Q-3:** `pnpm --filter @capakraken/web test:unit` — alle Tests grün
+
+**Phase 3 — Git-Integration**
+
+- [ ] **G-1:** `git add` aller ungestagten Änderungen (alle Ticket-Artefakte)
+- [ ] **G-2:** Commit mit Message: `security/platform: close audit findings #19–#26 (tests, CSP nonce, SSRF guard, runbook)`
+- [ ] **G-3:** `git push origin main`
+
+### Abhängigkeiten
+
+- V-1 bis V-8 sind unabhängig voneinander, aber sequenziell (ein Kommentar pro Ticket)
+- Q-1 bis Q-3 können nach allen V-Tasks parallel laufen
+- G-1/G-2/G-3 müssen nach Q-1..3 erfolgen (kein Commit bei roten Tests)
+
+### Akzeptanzkriterien
+
+- [ ] Alle 8 in-review-Tickets haben einen Bewertungskommentar
+- [ ] `pnpm test:unit` läuft grün (beide Pakete)
+- [ ] `tsc --noEmit` ohne Fehler
+- [ ] Alle neuen Dateien in einem sauberen Commit auf `main`
+- [ ] `git status` danach: working tree clean
+
+### Risiken & offene Fragen
+
+- **Ticket #23 (Active-Session):** Die Implementierung in früheren Sessions könnte durch spätere Auth-Fixes (jti→sid) überholt worden sein — genau prüfen
+- **Ticket #24 vs. #25:** Überlappen in `docker-compose.yml` — beide Tickets betreffen dieselbe Datei; ein Commit deckt beide ab
+- **Push auf main:** Direkt auf `main` — kein PR da kein Remote-Review-Prozess konfiguriert. Sicherstellen dass alle Tests grün sind

+
+## Ticket #25 — Docker/Env/Migration-Strategie
+
+### Anforderungsanalyse
+
+Ziel: Docker-Container-Lifecycle ohne manuelle Eingriffe.
+
+Konkrete Mängel:
+1. `REDIS_URL` in `docker-compose.yml` nutzt `${REDIS_URL:-redis://redis:6379}` — Host-Env-Var kann Docker-internen Wert überschreiben (gleiche Klasse wie das behobene `DATABASE_URL`-Problem)
+2. Migration-Strategy undokumentiert: DB per `db push` aufgebaut, dann Migration hinzugefügt → `migrate deploy` scheitert mit P3005, erforderte `migrate resolve --applied`
+3. Kein Developer-Runbook (Setup, Restart, DB-Ops fehlen)
+
+### Betroffene Dateien
+
+| Datei | Änderung |
+|---|---|
+| `docker-compose.yml` | `REDIS_URL` hardcoden |
+| `docs/developer-runbook.md` | create |
+
+### Task-Liste
+
+- [ ] **#25-T1:** `docker-compose.yml` — `REDIS_URL: redis://redis:6379` (Literal, kein `${}`)
+- [ ] **#25-T2:** `docs/developer-runbook.md` erstellen mit: Erstmaligem Setup, DB-Migration-Strategie inkl. P3005-Recovery, E2E_TEST_MODE-Erklärung, Container-Neustart-Checkliste

+
+## Ticket #26 — RBAC Datenzugriffs-Matrix E2E-Tests
+
+### Anforderungsanalyse
+
+Neue Testdatei `apps/web/e2e/dev-system/rbac-data-access.spec.ts` mit **Netzwerk-Ebene** tRPC-Response-Assertions (nicht nur UI-Sichtbarkeit).
+
+Grundlage `docs/route-access-matrix.md`:
+
+| tRPC-Prozedur | Audience | Admin | Manager | Viewer |
+|---|---|---|---|---|
+| `user.list` | `admin-only` | ✓ 200 | FORBIDDEN | FORBIDDEN |
+| `allocation.listView` | `planning-read` | ✓ 200 | ✓ 200 | FORBIDDEN |
+| `resource.listSummaries` | `resource-overview` | ✓ 200 | ✓ 200 | FORBIDDEN |
+| `user.listAssignable` | `manager-write` | ✓ 200 | ✓ 200 | FORBIDDEN |
+
+Technik: `page.evaluate()` mit `fetch()` gegen `/api/trpc/<proc>?batch=1&input=...` — läuft im Browser-Kontext der gespeicherten Session.
+
+tRPC GET-Format:
+```
+GET /api/trpc/<proc>?batch=1&input={"0":{"json":null}}
+Erfolg: [{"result":{"data":{"json":[...]}}}]
+Fehler: [{"error":{"json":{"data":{"code":"FORBIDDEN","httpStatus":403}}}}]
+```
+
+### Betroffene Dateien
+
+| Datei | Änderung |
+|---|---|
+| `apps/web/e2e/dev-system/rbac-data-access.spec.ts` | create |
+
+### Task-Liste
+
+- [ ] **#26-T1:** Datei erstellen mit `trpcQuery(page, procedure, input?)` Helper-Funktion
+- [ ] **#26-T2:** Admin-Describe-Block (4 Tests: alle 4 Prozeduren → Erfolg erwartet)
+- [ ] **#26-T3:** Manager-Describe-Block (4 Tests: `user.list` → FORBIDDEN, Rest → Erfolg)
+- [ ] **#26-T4:** Viewer-Describe-Block (4 Tests: alle → FORBIDDEN)
+- [ ] **#26-T5:** Smoke-Run: `pnpm exec playwright test e2e/dev-system/rbac-data-access.spec.ts --config=playwright.dev.config.ts`
+
+### Risiken
+
+- `allocation.listView` könnte ein Pflicht-Input-Objekt erfordern → Falls `BAD_REQUEST` statt FORBIDDEN, Schema im Router prüfen und minimalen Input übergeben
+- Viewer-Permissions aus DB-Seed (SystemRoleConfig) — prüfen ob VIEWER tatsächlich kein `VIEW_PLANNING` hat
