ci / rust (push) Has been cancelled
Single-user, LAN-reachable-but-gated. The web server is a backend-for-frontend:
- Login: POST /_auth/login {password} checks PUNKTFUNK_UI_PASSWORD (constant-time) and
sets a SEALED session cookie (h3 useSession / AES-GCM). server/middleware/auth.ts gates
every request — pages 302 → /login, /api → 401 — and FAILS CLOSED (503) when
PUNKTFUNK_UI_PASSWORD is unset, so a misconfigured LAN-exposed server admits no one.
- The management API stays loopback-only + token (never LAN-exposed). The proxy
(server/routes/api/[...].ts) injects PUNKTFUNK_MGMT_TOKEN server-side and drops the
browser's cookie before forwarding — the token never reaches the browser, which only
holds the session cookie.
Nitro doesn't auto-scan a server/ dir, so the Nitro plugin gets an explicit scanDirs to
pick up middleware + routes. Client: removed the localStorage token (server injects it);
the fetcher bounces to /login on 401; new /login page (bare, no shell); Settings drops the
token field and gains a Sign-out button; en/de strings.
Validated live end to end: unauth /→302, /api→401; wrong pw→401; right pw→200+cookie;
authed /api/v1/status→200 (proxied, mgmt token injected — the host required it); logout→
session cleared→401. tsc + build green.
