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.

enricobuehler 8103958169 fix(security): the plugin lane stops being a way in
Acts on the 2026-08-05 host security review. 36 of its 38 findings; the two
exceptions are recorded below and in the review doc.

The review's headline is that `plugin_may_access` was the one authorization
gate in the system that was allow-by-default — a hand-maintained denylist of
route prefixes, where every sibling gate is deny-by-default. Its own doc
comment names the two capabilities it exists to withhold, and both were
reachable one route over, because ~1450 commits of new routes were added and
the list was never one of the things anyone remembered to update.

So the gate is now an allowlist, and a test walks the live route table and
fails the build for any route that has not been deliberately classified for
both non-admin lanes. That test is the actual fix: it is what stops the next
route from arriving pre-authorized.

Route reachability and field authority turned out to be different questions.
A provider plugin has to be able to reconcile its own library entries — that
is what a scanner plugin IS — but `prep` and a `command` launch inside that
payload are handed to `/bin/sh -c` as the host user, and every execution site
documents them as operator-typed. Requests now carry the lane that authorized
them, and those two fields are refused to everyone but the operator's own
token.

The art proxy read any absolute path off disk in the host process, which on
Windows is LocalSystem, from a path the plugin lane could write and then read
back — so it yielded `mgmt-token`, which is full admin. It now serves only
real images (extension AND magic bytes, so a renamed secret fails), only from
inside an allowed root, only after canonicalization, and never over UNC; and
a path it would refuse to serve can no longer be persisted in the first place.

On Windows, the config-dir hardening was skipped exactly when it was needed —
it ran only in the branch that CREATES host.env, so the case it was written
for (a local user pre-created the directory and planted one) was the one case
it never ran in. It is now unconditional and first, an existing host.env is
re-owned, and the inheritable OWNER RIGHTS ACE that kept an attacker's files
theirs after the directory was re-owned is gone. The identity and token
readers were hardening the directory only on the path that GENERATED a new
secret, so a planted cert/key or token was adopted verbatim and permanently;
they harden before the first read now.

`ensure_admin_only_source` is implemented. The 2026-07-05 audit recorded it as
FIXED and it was in no commit in this repository's history — the local EoP it
described was live, and it is the payload half of the config-dir chain above.

Also: the three input planes are bounded and lossy like the mic plane on the
same loop already was; Android's library client no longer accepts any
publicly-trusted certificate for the pinned host; the usbip vhci nodes get
their own group instead of riding on `input`, which every packaging scriptlet
tells users to join; a registry URL can no longer inject a TOML table into
bunfig.toml; the pairing cooldown is charged before the arming state is read,
so armed/disarmed is no longer a free oracle; and the whole Low tier, of which
the two worth naming are a clipboard MIME NUL that panicked the host on one
control message, and an unauthenticated global logout that let any LAN peer
sign the operator out on a loop.

NOT fixed, deliberately:

  H-3 (plugin UIs framed allow-same-origin). Dropping allow-same-origin does
  not work: the document's origin goes opaque, its subresource requests are
  then cross-site, the SameSite=Lax session cookie is not sent, and every
  plugin asset 302s to /login. The "open in new tab" link is the same
  escalation with no iframe at all, so the sandbox attribute is not where this
  gets fixed either. It needs a second listener — a distinct origin that is
  still the same site — which changes the console's deploy model and wants
  on-glass validation. The mechanism and the dead end are written down at the
  iframe.

  H-6 registry authentication, whose other half lives in unom/infra. The
  in-repo halves are done: workflow_dispatch inputs no longer interpolate into
  run: blocks (one of them in the step holding UPDATE_MANIFEST_KEY), and the
  syft installer is pinned to its tag instead of main. Digest pinning is left
  until the registry is authenticated, because a tag — content-keyed or not —
  can simply be overwritten while anonymous pushes are accepted.

M-5 is half done: the oracle is closed, but binding the arming window needs
the console to learn the fingerprint first, which is a knock-then-bind flow
rather than an edit.

Verified: cargo fmt --all --check clean; cargo check --all-targets green on
Linux and on Windows (confirmed non-vacuous — a planted type error in
windows/install.rs fails the build); scripts/xcheck.sh windows check green;
cargo test -p punktfunk-host --bins 416 passed, the single failure being
gamestream::stream::tests::sender_delivers_batches, the known qemu-environmental
UDP-loopback flake that fails identically on clean main in the same container;
cargo test -p pf-clipboard 13 passed; web console typechecks.

enricobuehlerandClaude Opus 5 f2e1b9872c fix(web): four "fixes" from this branch that did not actually fix anything
A verification pass re-read every finding from the original sweep against the
code on this branch rather than against the commit messages. It found that four
of them were still broken, two because the edit I made was inert. Commit
messages claim; code decides.

- **The Storybook typecheck was never on.** `tsconfig.json` listed `.storybook`
  as a bare directory name, and tsc silently skips dot-prefixed directories in
  that form — so the entry typechecked nothing at all. Proved it by planting
  `export const __probe: string = 1` in `.storybook/preview.tsx` and watching
  `bun run lint` pass. `.storybook/**/*` is what actually pulls it in; the same
  probe now fails as it should.

- **The Moonlight stale-PIN reset was a no-op.** `submit.reset()` sat at the top
  of `onSubmit`, immediately before `submit.mutate(...)` — which moves the status
  to pending in the same update, so it cleared a flag that was already changing.
  The green "PIN sent" note therefore still greeted the next pairing attempt over
  an empty PIN box. It now resets on the transition that actually matters:
  `pin_pending` going false → true.

- **The session⇄game controls had the enforcement flag inverted**, and I never
  touched it. `enforced.length === 0 || …` reads an EMPTY list as "this build
  enforces everything", when the contract says the opposite in as many words:
  "Empty on a platform with no launch path (macOS), so the console can say so
  instead of offering a switch that does nothing". On exactly the platform the
  flag exists for, every control stayed live and reported success for an axis the
  host would never act on. Absent still means "assume it acts" — that is the
  compatible reading for an older host, and a different case from present-empty.

- **Logout stopped revoking after a restart.** The epoch was a module-level
  counter starting at 1, so it revoked within one process run and then reset —
  and since the seal key derives from the stable mgmt token, a cookie captured
  before a restart unsealed fine and was accepted again for the rest of its
  7-day TTL. One service restart undid the whole fix. It persists next to the
  host's config now. Verified: log out, restart the console, the captured cookie
  still 401s, a fresh login still works.

Two more the pass rated as partial, both worth closing:

- The plugin-UI response filter was a denylist of four header names, so
  `Clear-Site-Data` sailed through — a plugin error page could wipe `pf_session`
  and sign the operator out of the console, on our own origin, because the iframe
  is same-origin by design. It is an allowlist now; a plugin-supplied CSP,
  `X-Frame-Options` or CORS header no longer speaks for us either.

- A half-configured TLS setup now refuses to start instead of logging a warning
  and serving anyway. Neither shape can work — one path missing puts the login
  password on the LAN in the clear, and PUNKTFUNK_UI_SECURE without TLS marks the
  cookie Secure so the browser drops it and login can never stick. Exiting with a
  reason beats a console that looks fine and is not.

enricobuehlerandClaude Opus 5 b9b0df349d fix(web): the charts stop lying about time, and logging out logs you out
The stats charts drew every sample as an evenly-spaced slot, because recharts
defaults to a category axis. A capture that idled for two minutes rendered that
gap as a single step — so the one view you open specifically to find where the
time went was the view least able to show it. All three charts use a numeric time
axis now, so the spacing is the elapsed time.

They also joined samples across a session boundary into one continuous line,
implying a continuity that never existed: the stream stopped and somebody else
started a new one. A capture is split at each `session_id` change now. And the
live card plotted the whole capture-so-far every 2 s, re-serialising and
re-plotting an unbounded series for a capture left running all evening; it plots
a bounded tail and says so, with the full series still in the saved recording.

Logging out only deleted the browser's copy of the cookie. The session is
stateless, so a value captured beforehand — a shared machine, a shell history, a
TLS-inspecting proxy — stayed valid for its full 7-day TTL and there was nothing
the operator could do about it. Sessions carry an epoch now and logging out bumps
it, which invalidates every cookie issued so far. Verified end to end: a captured
cookie works, survives nothing across a logout, and a fresh login still works.

The rest:

- The update card could not show its own timeout warning. It was suppressed by a
  `job` field read from the last snapshot — which, when the host has gone away
  mid-job, is exactly the case the warning exists for. Nothing ever cleared the
  applying state either, so the card waited forever with no way out; there is a
  button now. "Check now" also surfaces the host's 429 instead of looking dead.
- A running install survives a reload: the job id lived only in component state,
  so refreshing lost sight of an install that was still running while the Install
  buttons stayed armed against a host that answers 409. The host keeps the list —
  ask it.
- An all-sources-failed catalog said "no plugins available". That is a successful
  request carrying nothing, not an empty store; it names the sources that failed.
- The Installed tab rendered "vundefined" for a plugin with no recorded version
  (nullable in the contract, typed required here).
- The Displays "In effect" badges were computed from the local draft, so they
  restated the operator's unsaved edits back to them as though the host had
  adopted them. They read the API's `effective` now. A failed background poll no
  longer replaces a form someone is editing, and leaving the page with unsaved
  edits prompts — the old `beforeunload` guard never fired for in-app navigation,
  which is how you actually leave.
- Enter or Space on a preset's rename/update/delete icon applied the preset
  instead of running the action: keydown bubbled to the card.
- Dates follow the console's locale, not the browser's. The dashboard's
  PIN-pending tile says "Waiting"/"None" instead of "●"/"—".
- The Bun entry warns when TLS is half-configured, or when PUNKTFUNK_UI_SECURE
  is set without it — both of which silently break login.

enricobuehlerandClaude Opus 5 55e01c1460 fix(web): stop shipping 7 MB of sound the console cannot play
`@unom/ui/button` reaches `sound/defaults.js`, which resolves two game-UI sprite
sheets with `new URL(…, import.meta.url)` at module scope — a 4.8 MB .wav and a
2.2 MB .mp3. Vite emitted both into the build, so they rode into the Windows
installer and the .deb. The console never mounts UnomProviders, so no player is
bundled and not one byte of it could ever be played. A build-time rewrite of
those two expressions takes the asset payload from 8.2 MB to 1.5 MB; the login
page and the button chunk are unchanged. Deleting the plugin is the whole revert
if the console ever wants click sounds.

Also:

- `bun run dev` forwards the management bearer, so developing against a real
  host stops 401ing into a /login bounce that dev has no gate to satisfy.
- `check-i18n` runs after `build`, not only inside `codegen`. It exists to stop a
  zero-message console shipping, and the CI job and the installer build both
  install with `--ignore-scripts`, so it had never once run where it mattered.
- Bun's idle timeout goes from its 10 s default to 120 s. The host sends SSE
  keep-alives every 15 s, so anything long-lived proxied through the console was
  cut by us first — which the event stream is about to depend on.
- The typecheck covers the Storybook config and preview.

enricobuehlerandClaude Opus 5 4575134c21 fix(web): one bad password from anywhere stops locking out the whole console
The console's login throttle was documented as per-IP and was not. Nitro's
`localFetch` hands the app a synthetic request whose socket has no
`remoteAddress`, so `getRequestIP()` returned undefined for every request and
every attempt was charged to one shared "unknown" bucket. Five wrong guesses
from any LAN peer locked out everyone — including the operator, and including
the update-apply route, which shares that budget. The Bun entry is the only
place the real peer is knowable, so it now stamps it into a header (deleting
any client-supplied copy first) and `peerAddress()` reads it back.

Verified on a real build bound to 0.0.0.0: seven wrong logins from 127.0.0.1
lock 127.0.0.1 out, a different peer still logs in on the first try, and a
request forging the header is charged to its real address.

Also on the way through:

- Installing an unreviewed package and adding a catalog source now re-ask for
  the console password, like applying an update already did. A 7-day session
  cookie should not be able to run new code on the host, and `store/install`
  with `accept_unverified` did exactly that through the generic passthrough.
  The gate sits at the trust boundary — adding a source, or a raw spec — not
  on every install from a source the operator already chose to trust.
- The ui-credential denylist is matched against the normalised path too, so
  `/api//v1/...` and friends can no longer walk around it.
- The console serves nosniff, a no-referrer policy, and a CSP that pins
  frame-ancestors, object-src and base-uri.
- A plugin UI's response no longer re-emits the content-encoding that `fetch`
  already decoded (which made compressed plugin pages fail to load), no longer
  sets cookies on the console's origin, and OPTIONS reaches the plugin instead
  of being refused 405 by us.
- An unreachable host reads as 502 on these routes, matching the passthrough,
  instead of a bare 500.

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.
