style(plugin-kit): adopt the biome config its own plugins already use
The kit had NO biome config and no lint script, while every plugin repo that
consumes it has both. So its source quietly drifted — unused imports, unsorted
imports, formatting — with nothing to catch any of it. Running biome here for
the first time reported 20 findings across 8 files.
Adds `plugin-kit/biome.json` mirroring the plugin repos' (tab indent, double
quotes, recommended lint preset, organizeImports), a `check` script, and
`@biomejs/biome` pinned to the same `^2.5.2` the plugins pin — without that pin
`bunx biome` resolved 2.4.6, which rejects the 2.5 `rules.preset` key.
Two deliberate differences from the plugin repos' copy:
* no `vcs.useIgnoreFile` — those are standalone repos with a .gitignore beside
the config; plugin-kit is a directory inside this one, and biome errors with
"couldn't find an ignore file". The `files.includes` exclusions cover it.
* `!examples/**/dist` instead of `!ui/dist` — the kit has examples, not a UI.
`css.parser.tailwindDirectives` is carried over and is load-bearing: without it
biome cannot parse `@theme` in src/theme.css and reports three parse errors on
CSS that is perfectly valid Tailwind v4.
Everything here is formatter/import churn except two real findings, both fixed:
* `Layer` (library/define.ts) and `Cause` (sync-engine.ts) were imported and
never used;
* test/spike-httpapi.test.ts read `(reg?.body as …).ui.secret` one line after
`expect(reg).toBeDefined()`. The optional chain undoes the assertion: had
`reg` been undefined the `.ui` access would throw a TypeError instead of
failing the test readably. Now asserted to the type system too.
Wired into plugin-kit-publish.yml as a `Lint & format` step ahead of Typecheck,
so this cannot rot again.
Gates after: biome clean (42 files), tsc clean, 67/67 tests, build clean.

fix(security): plugin UIs get their own origin
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.

feat(plugin-kit): @punktfunk/plugin-kit 0.1.0 — the Effect plugin framework
The ~80% of every plugin that was copy-pasted (rom-manager ↔ playnite), extracted as one Effect-v4 package: - runtime: definePluginKit — async-main boundary hiding a ManagedRuntime (two-effect-instances discipline), signal-driven interruption with a bounded shutdown grace - config: Schema-driven raw round-trip (defaults only in the Schema via withDecodingDefaultKey + encodingStrategy omit; file stays authored-shape), atomic writes, world-writable refusal, changes stream - cache-store: disposable derived state, corrupt→empty, write-through - reconcile: kit-owned provider wire schemas + typed client over the skew-safe untyped pf.request seam - sync-engine: generic poll/watch/debounce/single-flight-coalesce/ fingerprint-skip engine with a status PubSub (the SSE feed) - ui-server + sse: effect/unstable/httpapi behind servePluginUi with core-only env layers (validated by the phase-0 spikes); raw SSE route (httpapi has no event-stream media type) - cli: minimal command dispatcher reusing the plugin layer graph (deliberately not effect/unstable/cli — it needs platform packages) - react subpath: plugin router (path→hash→fallback deep-link restore + pf-ui:navigate bridge), ResultGate, sseAtom, resolvePluginBase - theme.css: the console's violet identity packaged for plugin UIs 18 bun tests incl. the two phase-0 spikes; publish workflow mirrors sdk-publish (tag plugin-kit-v*; 0.1.0 published manually).
