Die live gesetzte Annotation traefik.ingress.kubernetes.io/router.middlewares
fehlte in den Manifesten (Backend und Frontend). Sie schuetzt vor
Direktzugriff am Origin vorbei, nicht vor fremden Cloudflare-Zonen.

Verified each finding against the real codebase first, since the review's
diff was polluted by a stale leftover agent-worktree copy under
.claude/worktrees/ (now removed) that made several already-fixed or
never-broken issues look current (CORS, missing typecheck script, PWA
icons, font CSS, Helmet/Swagger CSP - all confirmed fine live, not
touched).
Real fixes:
- main.ts: fail-fast on missing DATABASE_URL/JWT_ACCESS_SECRET at boot,
call enableShutdownHooks() so PrismaService.onModuleDestroy() actually
runs on SIGTERM during k8s rolling deploys, PORT fallback 3000 -> 3001
to match every other place that documents the port.
- health.controller.ts: log the real underlying DB error instead of
discarding it, add a 5s timeout to the readiness query so a hung DB
fails the probe fast instead of blocking indefinitely.
- Frontend Dockerfile: declare ARG/ENV NEXT_PUBLIC_API_URL before the
build step, since Next.js inlines NEXT_PUBLIC_* vars at build time and
a runtime-only ConfigMap value never reaches the compiled bundle.
- Backend ingress.yaml: drop the no-op rewrite-target regex for a plain
prefix path (identical behavior, less confusing).
Security review findings (HIGH-1/2/3, MEDIUM):
- Rate limiting via @nestjs/throttler: global 100 req/min default, stricter
10 req/min on login and refresh. Also closes the MEDIUM finding (public
batch-lookup enumeration) since it now sits behind the global limit too.
Trust the K8s ingress's single proxy hop so throttling keys off the real
client IP, not the ingress pod's IP.
- Auth events (login success/failure, logout, token refresh) are now
audit-logged via new AuditAction values, closing the gap where the
project's own audit-log principle never actually covered the Auth module.
- Refresh-token cookie now defaults to Secure=true (opt out only via
COOKIE_SECURE=false for local HTTP dev), instead of keying off NODE_ENV
which was never set in the K8s deploy templates. Added a TLS block +
cert-manager annotation to both the backend and frontend ingress
templates, which previously had no HTTPS termination configured at all.
