Closes H-3 of the 2026-08-05 review, the last of its six highs. A plugin's
interface was reverse-proxied onto the console's own origin and framed with
`allow-same-origin`, so plugin JS ran as first-party code on that origin: one
`fetch('/api/**', {credentials:'same-origin'})` and the BFF attached the
operator's ADMIN bearer. That reached everything `plugin_may_access` withholds
— arm pairing, read the host PIN, approve a device, read `/hooks`. The "open
in new tab" link was the same escalation with no iframe involved at all.

The fix is not a sandbox attribute, and it is worth writing down why, because
the obvious change is the one that does not work. Dropping `allow-same-origin`
gives the frame an OPAQUE origin; its subresource requests are then cross-site;
the `SameSite=Lax` session cookie stops being sent; every plugin asset 302s to
/login and the frame is blank. Nothing about the new-tab link is helped either.

So the origin moves instead. A second listener on its own port (default
PORT + 1) serves plugin UIs and nothing else:

  different ORIGIN — scheme+host+PORT — so the same-origin policy separates the
                     plugin from the console: it cannot read the console's DOM,
                     its cross-origin fetch of /api/** is unreadable (no CORS)
                     and cannot mutate (Sec-Fetch-Site sees same-site).
  same SITE        — cookie scope ignores the port and SameSite is computed on
                     the site, so the session cookie still reaches the plugin
                     listener and plugin pages keep working.

Enforcement is two refusals and both are load-bearing: the console origin
refuses /plugin-ui/**, and the plugin origin refuses everything ELSE — above
all /api/**, which would otherwise hand the admin bearer right back to plugin
JS that is now same-origin with that listener. Both are unconditional: if the
plugin port cannot be bound, plugin UIs are DISABLED and the console says so,
rather than falling back to the arrangement this exists to remove.

Two consequences that would otherwise bite in the field:

  The port has to be open. Done for the Windows netsh rule, the firewalld
  service and the ufw profile.

  A browser stores a self-signed-certificate exception per ORIGIN, including
  the port — and a certificate interstitial can never be shown inside an
  iframe, so the frame would just sit blank with nothing on screen explaining
  why. A `no-cors` probe distinguishes it (a TLS failure rejects; any HTTP
  answer, even 401, resolves) and the console renders a card linking the
  operator to open the port once in a real tab.

Also here: the health probe moved server-side to the console origin (it used
to rely on being same-origin with the plugin), the postMessage listener now
verifies `event.origin` — a real check rather than a tautology — and
plugin-kit's `postMessage(..., "*")` is documented as load-bearing, since
narrowing it to `location.origin` would now target the plugin's own origin and
silently drop every message.

Verified against a running console with a fake mgmt API and a fake plugin:
console /plugin-ui/** → 404; plugin-origin /api/v1/hooks, /, /login,
/_auth/logout → 404; plugin page loads 200 through its own origin;
unauthenticated plugin origin → 401 (not a redirect to a /login it does not
serve); a forged x-pf-listener header changes nothing on either listener; the
plugin's own Clear-Site-Data / Access-Control-Allow-Origin / Set-Cookie are
dropped by the proxy allowlist; the plugin origin's CSP names the console as
its only frame-ancestors source; and with the port squatted, ui-config reports
`unavailable`, the console still refuses /plugin-ui/**, and the console itself
keeps working.

Still wants on-glass confirmation in a real browser — the cookie and framing
behaviour is reasoned from spec, not observed.

cargo fmt --all --check clean; cargo check -p punktfunk-host --all-targets
green on Windows; web console builds and typechecks.

enricobuehlerandClaude Opus 4.8 f87a43f42d feat(web): harden login gate — throttle, scoped TLS, token-derived seal key
Remediates the two web-console residuals from the 2026-07-05 posture audit:

- Brute-force throttle (loginThrottle.ts): per-IP exponential backoff
  after 5 free attempts, plus a global floor for spread-out floods, keyed
  on the socket peer IP (not spoofable X-Forwarded-For) with a size-capped
  map. The constant-time compare already stopped the timing leak; this
  bounds guess *volume* against a by-design LAN-exposed console.
- Session seal key now derives from the high-entropy mgmt token instead of
  the low-entropy login password, so a captured cookie is no longer an
  offline password oracle. Falls back to the password only when no token
  is configured (dev/local). Rotating the token now invalidates sessions.
- Replace the process-wide NODE_TLS_REJECT_UNAUTHORIZED=0 with per-request
  Bun TLS scoped to the loopback proxy hop; a non-loopback mgmt URL now
  verifies normally. Dropped the env var from the systemd unit, Steam Deck
  installer, Windows run scripts, env examples, and web README.

Port 3000 collides with half the dev-server ecosystem; 47992 sits next
to the mgmt API (47990) in the punktfunk port family. Updates the run
scripts, systemd/scheduled-task units, Dockerfile, Windows firewall
rule + installer, packaging, and every doc that referenced :3000.

enricobuehlerandClaude Opus 4.8 ae51276a03 feat(web): consolidate paired devices, self-contained sections, docs + lint
Web console
- Pairing/Library/Stats refactored into self-contained subsections that each own
  their own queries + mutations; a shared slot-based layout (view.tsx) is filled by
  the live page (containers) and Storybook (pure cards + fixtures) so the layout can't
  drift.
- All paired devices in one list on Pairing with a protocol column (punktfunk/1 +
  Moonlight), routing each unpair to the right endpoint; the redundant Clients page is
  removed.
- Library: overview grid split from the add/edit form into separate files.
- Login screen links out to the docs.

Docs
- "Console login password" section on every host page (apt/RPM/Bazzite/SteamOS/Windows)
  plus a new "Forgot your Password?" troubleshooting page, linked from the login screen.
- Console served as HTTP/1.1 over TLS (drop the unusable HTTP/3 advertising) across the
  Bun entry, launchers, systemd units, and packaging.

Tooling
- Biome now respects .gitignore (stops linting generated code), config migrated to
  2.5.1; all lint issues fixed cleanly.

Also includes this branch's in-progress host, Apple client, packaging, and CI changes.

enricobuehlerandClaude Opus 4.8 4a7cf9af7b feat(packaging/web): bundle the web console into the apt install (punktfunk-web)
Every user needs the console for pairing, so ship it via apt, auto-wired to the
host — no manual bun/env setup. New punktfunk-web .deb (Architecture: all,
Depends: nodejs >= 20 — runs the node-server build under apt-native node, no
bundled bun):

- packaging/debian/build-web-deb.sh: stages web/.output (server + public) + a
  /usr/bin/punktfunk-web-server wrapper (node) + the systemd --user units + the
  web.env template + docs. Refuses a bun bundle (Bun.serve) as a wrong-preset guard.
- scripts/punktfunk-web.service: --user unit on :3000, EnvironmentFile sources the
  host's ~/.config/punktfunk/mgmt-token (the shared bearer) + the generated
  web-password; sets PUNKTFUNK_MGMT_URL=https://127.0.0.1:47990 +
  NODE_TLS_REJECT_UNAUTHORIZED=0 (loopback self-signed cert). Restart=on-failure
  rides out the host-writes-token-first ordering.
- scripts/punktfunk-web-init.service + web-init.sh: --user one-shot that generates
  the login password (a .deb postinst runs as root → wrong $HOME) and surfaces it
  to the journal.
- build-deb.sh: punktfunk-host now Recommends punktfunk-web (apt pulls it by
  default; headless boxes opt out with --no-install-recommends).
- deb.yml: build the web console + smoke-boot it under node (gate the .deb on a
  real /login 200) + build-web-deb.sh; the publish loop globs it automatically.
- web/{.env.example,web.env.example}: document the auto-wiring vs a manual deploy.

End state: `apt install punktfunk-host` pulls punktfunk-web; enable both --user
services; the console logs in (password from the journal) and proxies the host's
HTTPS mgmt API with the shared token — zero hand-edited env. Local .deb build +
node smoke-boot verified.

enricobuehlerandClaude Opus 4.8 f4e37ac3b3 fix(web): default mgmt proxy to the HTTPS self-signed mgmt API
The mgmt API serves HTTPS with the host's self-signed identity cert and requires
mTLS-or-bearer auth (the mTLS work), but the web console's proxy still defaulted to
`http://127.0.0.1:47990` — so a deployment copying .env.example got a plain-HTTP
request to an HTTPS port (→ 502 Bad Gateway, observed live on the Bazzite box).

- .env.example + server/util/auth.ts + vite.config.ts: default PUNKTFUNK_MGMT_URL to
  https://127.0.0.1:47990.
- vite dev proxy: `secure: false` (the host cert is self-signed).
- Document that the deployment needs PUNKTFUNK_MGMT_TOKEN (matching the host's) and
  NODE_TLS_REJECT_UNAUTHORIZED=0 — the web server's only outbound TLS is the loopback
  hop to the host's own self-signed cert, so disabling verify there is scoped + safe.

The running Bazzite box is already fixed live (web.env → https + token + cert-skip,
verified: login 200, /api/v1/status 200). This makes fresh deployments correct.

enricobuehlerandClaude Opus 4.8 d356d1534f feat(web): login-gated BFF auth — sealed session cookie + server-side token injection
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.
