Workstream 3: Authentifizierung & Zugriffskontrolle (Phase 2)
Einheitliche Auth.js-v5-Sitzung (role + brigadeId) über Authentik-OIDC (Platform-Admins) und Credentials/argon2id (Wehr-Konten). Default-deny dreifach: Middleware + Layout-Guard im (app)-Segment + 401/403 in API-Routen und Guards in Server Actions. - src/lib/auth/roles.ts: Rollen als Single Source of Truth (aus DB-Enum abgeleitet) + canAccessBrigade-Wehr-Scoping. - src/lib/auth/password.ts: argon2id mit OWASP-Minima (Node-only). - src/lib/auth/rate-limit.ts: Sliding Window (5 Fehlversuche/15 min) auf login_attempts; greift im authorize-Callback (beide Login-Pfade). - src/auth.config.ts: Edge-sicher (kein @/db, kein argon2), Cookie-secure/ __Secure- umgebungsabhaengig (isHttps). - src/auth.ts: Credentials + DB-Lookup + Rate-Limit + Authentik-signIn-Gate. - src/middleware.ts: Allowlist inkl. api/auth, api/health, login, Statics. - src/lib/auth/guards.ts: requireSession/requireRole/requirePlatformAdmin/ requireWehrAdmin/requireOwnBrigade + API-Varianten (401/403 ohne Daten-Leak). - (app)/layout.tsx: requireSession() als erste Zeile aktiviert. - (auth)/login: page + login-form + Server Actions (Zod, Authentik + lokal). - api/auth/[...nextauth]/route.ts; api/health/route.ts (anonym 200). - scripts/seed-auth.ts: idempotenter Erst-Admin-Seed. - Typen: src/types/next-auth.d.ts. - Tests: Unit (password/roles/rate-limit) gruen; E2E-Gating-Spec geschrieben (deferred, kein Server/DB in Sandbox). Offline verifiziert: tsc --noEmit, next lint, next build, drizzle-kit check, vitest (13 Unit-Tests) je ohne Fehler; Edge-Safety-Grep ohne DB/argon2-Import.
