A client can now request which compositor backend the host drives its virtual
output on (gamescope/KWin/Mutter/wlroots). The host honors the request if that
backend is available, else falls back to auto-detect and reports the resolved
choice back — wire-compatible both directions (no ABI bump).
Protocol (punktfunk-core):
- New CompositorPref (config.rs): Auto|Kwin|Wlroots|Mutter|Gamescope with
u8/name mappings. Appended as one optional byte to Hello (client preference)
and Welcome (host's resolved choice). Both decoders already tolerate trailing
bytes, so old↔new interop is preserved — ABI_VERSION stays 2. Round-trip +
back-compat (truncated-message) tests.
- C ABI: punktfunk_connect_ex(compositor) + PUNKTFUNK_COMPOSITOR_* constants;
punktfunk_connect delegates with AUTO, so the existing symbol is unchanged.
NativeClient::connect / worker_main thread the preference through.
Host:
- vdisplay::available() enumerates usable backends via cheap, side-effect-free
probes (KWin zkde global, gamescope binary+version, GNOME/Sway env), plus
Compositor id/label/as_pref/from_pref/all helpers.
- m3 handshake resolves the preference to a concrete backend during the
handshake (pick_compositor pure + resolved logging), reports it in Welcome,
and threads it into virtual_stream (replacing the unconditional detect()).
- mgmt GET /v1/compositors lists every backend with availability + the
auto-detected default (OpenAPI regenerated).
Client:
- punktfunk-client-rs --compositor NAME; logs the host's resolved choice from
the Welcome ("session offer … compositor=…").
Web console:
- Host page gains a Compositors card (availability + default badges) via the
codegen'd useListCompositors hook; en/de strings added.
Also fixes a pre-existing, env-dependent test-isolation bug:
mgmt::tests::paired_clients_list_and_unpair seeded the real
~/.config/punktfunk/paired.json (AppState::new loads it), so a real
GameStream-paired client leaked into body[0] on a dev box — now cleared first.
Live-validated against headless KWin: --compositor kwin honored, --compositor
mutter falls back to kwin (available=[kwin, gamescope]), resolved choice
round-trips to the client. Tests: +6 (wire/back-compat, resolution precedence,
endpoint); workspace green, clippy/fmt clean, C ABI harness PASS at abi_version=2,
web typecheck + build clean.

Multi-agent security review of 9856c04 (4 dimensions, 2-skeptic verification):
- CRITICAL functional+security: the session cookie inherited h3's Secure=true default;
browsers DROP Secure cookies over plain http://, so login silently failed on a LAN HTTP
client (worked only on localhost, a secure context — which is why the live test passed).
Now set the cookie attributes explicitly: HttpOnly + SameSite=Lax + Path=/, and Secure
only when PUNKTFUNK_UI_SECURE=1 (behind TLS). Verified: Set-Cookie no longer has Secure.
- Gate bypass: isPublicPath allowlisted any path ending in .json/.css/.png/etc., so
/api/v1/openapi.json (served unauthenticated on the mgmt side too) leaked the whole API
schema through the token-injecting proxy. Now /api is ALWAYS gated and the generic
extension allowlist is gone (client assets are all under /assets/, still allowlisted).
Verified: /api/v1/openapi.json and /api/v1/status.json → 401.
- Session lifetime: added maxAge (7d) — bounds a stolen cookie (cookie Max-Age + iron seal
TTL); previously never expired.
- Open redirect: the post-login `next` accepted protocol-relative `//evil.com`. Hardened
client + added safeNextPath() (same-origin path only).
Re-validated end to end: login assets public (200), /api/openapi.json gated (401), authed
/api/v1/status (200), unauth /→302. tsc + build green.

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.

Browser UI for the host's management REST API (mgmt.rs / docs/api/openapi.json).
Stack, exactly as specified:
- TanStack Start (Vite, SPA mode) — file-based routes, SSR shell + client hydration.
- React Query via orval codegen from the checked-in OpenAPI spec: a custom fetch mutator
(src/api/fetcher.ts) centralizes the base URL, the bearer token (Settings → localStorage),
JSON, and a throwing ApiError; the query client skips retries on 4xx. orval returns the
response body directly (includeHttpResponseReturnType:false) so a query's `.data` is the
typed payload; GET→useQuery, POST/DELETE→useMutation by method.
- shadcn/ui on Tailwind v4 (CSS-first tokens, dark-first) — button/card/badge/input/label/
table/skeleton primitives hand-authored from the canonical source.
- Paraglide i18n (en + de) with a reactive useLocale() hook and a language switcher.
Pages: dashboard (live status — video/audio/session/stream, stop-session + request-IDR,
2s polling), host (identity/codecs/ports), clients (paired list + unpair), pairing (PIN
submit, polls pin_pending), settings (API token + language).
Dev server proxies /api → 127.0.0.1:47990 (same-origin, no CORS; PUNKTFUNK_MGMT_URL to
override). Generated code (orval client, paraglide runtime, routeTree) is gitignored and
reproduced by `pnpm codegen` (prepare/pre* scripts). Validated live against `serve`: API
shapes match, dev proxy works, SSR shell renders the localized nav, build + tsc green.
