Arm streaming-perf-stats capture from the web console, play, stop, and review the run as graphs; finished captures are saved to disk as browsable/exportable recordings. Covers both the native punktfunk/1 path and GameStream. - stats_recorder.rs: one shared Arc<StatsRecorder> ring (created in gamestream::serve, shared with the mgmt API + both streaming loops, mirroring NativePairing). The hot-path gate is a runtime AtomicBool that replaces the startup-only PUNKTFUNK_PERF for *recording* (PERF stdout logging unchanged); bounded ring (~3 h); atomic temp+rename writes to ~/.config/punktfunk/captures/*.json; path-traversal-safe ids; poison-resilient locks. - native (punktfunk1.rs) + GameStream (stream.rs) emit a StatsSample at their existing ~2 s / ~1 s aggregation boundary — per-stage latency p50/p99, fps new/repeat, goodput, loss/FEC deltas — with no new per-frame work beyond the cheap atomic check. FrameMsg.was_measured keeps pre-arm in-flight frames out of the first window's percentiles (without zeroing the Windows-relay path's fps/encode). - mgmt.rs: 7 bearer-only /api/v1/stats/* endpoints (capture start/stop/status/live; recordings list/get/delete); api/openapi.json regenerated, in sync. - web: new "Performance" page (recharts, rendered SSR-safe) — capture control, live graphs while armed, recordings table (view / download-JSON / delete), and a detail view with the latency stacked-area bottleneck breakdown (p50/p99 toggle) + throughput + health. Charts adapt to either path's stage set. Design: design/stats-capture-plan.md. Built and adversarially reviewed via a multi-agent workflow; workspace build/clippy(-D warnings)/fmt/tests green, OpenAPI no-drift. Not yet on-glass validated against a live session.

punktfunk web — management console
The browser UI for the punktfunk host's management REST API (crates/punktfunk-host/src/mgmt.rs,
OpenAPI at api/openapi.json). It shows live status, host capabilities, paired
clients, the pairing-PIN flow, and session controls.
Stack: TanStack Start (full SSR) on Bun via Nitro v2 (bun preset) · React
Query through orval codegen from the OpenAPI spec · @unom/ui
— the shared punktfunk/unom design system the marketing site + docs are built on (Tailwind v4,
animated components on the violet brand over dark chrome) ·
Paraglide i18n (en/de). Package manager + runtime: Bun.
The @unom registry mapping lives in .npmrc; the auth token comes from
~/.npmrc (or a CI secret).
Develop
# from web/ — Bun is the toolchain (https://bun.sh)
bun install # runs `prepare` → codegen (orval + paraglide)
bun run dev # http://localhost:3000
# The dev server proxies /api → https://127.0.0.1:47990 (the host's mgmt API; it serves HTTPS
# with the host's self-signed identity cert — the dev proxy uses `secure: false`).
# Point it elsewhere: PUNKTFUNK_MGMT_URL=https://<host>:47990 bun run dev
Start a host with the management API up:
# from the repo root — `serve` brings up the native punktfunk/1 plane + the mgmt API (the console
# only needs the mgmt API; add --gamestream too if you also want the Moonlight surface):
WAYLAND_DISPLAY=wayland-kde XDG_CURRENT_DESKTOP=KDE \
cargo run -rp punktfunk-host -- serve
# loopback :47990, no token (a token is mandatory for non-loopback binds).
If the host runs with --mgmt-token, set it under Settings → API token (stored in
localStorage, sent as Authorization: Bearer … by the orval fetcher).
Build & run (Nitro + Bun)
bun run build # → .output/ (Nitro server, `bun` preset, + .output/public assets)
PORT=3000 HOST=0.0.0.0 \
PUNKTFUNK_UI_PASSWORD=… PUNKTFUNK_MGMT_TOKEN=… \
PUNKTFUNK_MGMT_URL=https://127.0.0.1:47990 NODE_TLS_REJECT_UNAUTHORIZED=0 \
bun run start # = bun run .output/server/index.mjs
# (the mgmt API is HTTPS w/ the host's self-signed cert on loopback → the proxy's fetch needs
# NODE_TLS_REJECT_UNAUTHORIZED=0; it makes no other outbound TLS calls. See .env.example.)
bun run lint # tsc --noEmit
The built Nitro Bun server SSR-renders the app and is the only thing exposed on the LAN.
Run it on the same box as the host; it serves the console on :3000 (or $PORT).
Auth (backend-for-frontend)
Single-user, login-gated. Config via env (see .env.example):
- The console requires a login (
PUNKTFUNK_UI_PASSWORD). On success the server sets a sealed session cookie (h3useSession, AES-GCM).server/middleware/auth.tsgates every request — pages redirect to/login,/apireturns 401 — and fails closed (503) ifPUNKTFUNK_UI_PASSWORDis unset, so a misconfigured LAN server admits no one. - The management API stays loopback-only + token — never LAN-exposed. The web server
holds
PUNKTFUNK_MGMT_TOKENserver-side and injects it when proxying/api/**→PUNKTFUNK_MGMT_URL(server/routes/api/[...].ts). The token never reaches the browser; the browser only ever holds the session cookie.
So: browser ──password──▶ web server (session cookie) ──mgmt token, server-side──▶ mgmt API.
Run the host with a matching token: cargo run -rp punktfunk-host -- serve +
PUNKTFUNK_MGMT_TOKEN=… (or --mgmt-token …). vite dev has no gate (localhost-only) and
proxies straight to the loopback mgmt API.
Toolchain notes (load-bearing): TanStack Start's
start-plugin-corepeer-requires Vite ≥ 7 — on Vite 6 the build's prerender/post-build hook silently doesn't run.@vitejs/plugin-reactmust match Vite (v5 ↔ Vite 7, v6 ↔ Vite 8); it's required even for dev (TanStack Start's dev mode needs the React Refresh runtime, else a blank screen). Nitro is the server target — without itvite buildonly emits client+SSR bundles, no deployable server. The Nitrobunpreset makes.output/server/index.mjsBun-runnable.
Codegen
Generated code is not committed (gitignored) — reproduced from sources:
bun run codegen— regenerate the API client (orval) + i18n runtime (paraglide). Runs onbun install(prepare) and beforedev/build(pre*for orval; the Vite plugin compiles paraglide on dev/build).- After a management-API change, regenerate the spec on the Rust side first:
cargo run -p punktfunk-host -- openapi > api/openapi.json, thenbun run api:gen.
