audit.yml's three blocking bun-audit legs (web, sdk, plugin-kit) were all red on
main. Ten findings in sdk and plugin-kit, eight in web; every one of them a
transitive dependency, none reachable by bumping a direct dep.
web already carried the right mechanism — an `overrides` block whose `undici` and
`fast-uri` pins had simply gone stale — so it needed four bumps, not a new idea:
undici 7.28.0 -> ^7.29.0 and fast-uri 3.1.4 -> ^3.1.5 for the reported advisories,
plus postcss ^8.5.10 -> ^8.5.25 and brace-expansion ^5.0.8 -> ^5.0.9 for two more
that were published after the failing run and would have gone red on the next
audit anyway. All four stay inside their current major.
sdk and plugin-kit were harder and the fix deserves an explanation. Their single
finding is undici 8.7.0/8.8.0 pulled in by @effect/platform-node, a devDependency
pinned at 4.0.0-beta.98. That dependency already declares `undici: ^8.7.0`, which
permits the fixed 8.10.0 — the vulnerable version survives purely as a stale
lockfile resolution. Nothing bumps it in place: `bun update` only walks direct
dependencies, `bun install --force` preserves a resolution that still satisfies
its range, and every platform-node release through beta.103 declares the same
`^8.7.0`, so moving the dep changes nothing. Bun rejects the scoped form outright
("Bun currently does not support nested resolutions"), so a flat `overrides` entry
is the only mechanism available, and it necessarily also moves sdk's top-level
undici from 7.x to 8.x.
That is safe here, and was verified rather than assumed. The only source use is
sdk/src/config.ts, which does `new Agent({ connect: { ca } })` behind a dynamic
import and a try/catch with a documented plain-fetch fallback; `Agent` and its
`connect` option are unchanged between undici 7 and 8. sdk typechecks and its 72
tests pass against 8.10.0; plugin-kit typechecks and its 20 tests pass. Both trees
now dedupe to a single undici 8.10.0.
Consumers are deliberately untouched: `overrides` apply only at the root of the
tree that declares them and are not honored when the package is installed as a
dependency, so sdk's published `optionalDependencies: { undici: "^7.0.0" }` is
left alone — a consumer resolves the latest 7.x, which is the fixed 7.29.0. The
override governs this repo's own tree, which is exactly what audit.yml checks.
Worth knowing: sdk's dev tree therefore exercises undici 8 while consumers get 7.
One trap found on the way. Running `bun install` over plugin-kit's existing
lockfile emitted a lockfile with two byte-identical `@punktfunk/host` entries —
its `file:../sdk` dependency crossed with the new override — and bun then refuses
its own output with "Error loading lockfile: InvalidPackageKey". That reads as a
tooling error rather than a finding, so it would have taken the audit gate down
while looking like something else entirely. Regenerating the lockfile from scratch
produces a valid single entry; all three lockfiles are checked for duplicate keys.
Also worth recording, because it nearly shipped: deleting the pinned nested entry
from a lockfile makes `bun audit` report "No vulnerabilities found" while the
vulnerable copy is still installed on disk. bun audit reads the lockfile, not
node_modules. That is a vacuous green, not a fix, and was rejected.
Verified: `bun audit` clean in all three trees; web builds and typechecks (its
typecheck needs the build first, which generates routeTree.gen); sdk 72/72 and
plugin-kit 20/20 tests pass.
@punktfunk/plugin-kit
The Effect-based framework punktfunk plugins are built on. It owns everything that is the
same in every plugin — lifecycle, config/state, the sync engine, UI serving, the CLI
scaffold, logging — so a plugin is just its domain logic, its HttpApi contract, and its UI.
The reference consumer (and the blueprint to copy) is
punktfunk-plugin-rom-manager.
Built on @punktfunk/host (the SDK stays the low-level host client; the kit is
the opinionated plugin layer on top). Effect 4.x and the SDK are peer dependencies —
the plugin's own copies are the only copies.
The one rule: async at the boundary, Effect inside
The packaged runner bundles its own effect + SDK; a plugin's imports resolve to the
plugin's node_modules. Effect values must therefore never cross the plugin boundary
(Context.Tag identity is per-instance). definePluginKit enforces this by construction:
you write Effect, it exports a plain async-main PluginDef, and a ManagedRuntime
built from your effect instance runs everything. SIGINT/SIGTERM interrupt the plugin
fiber (scoped finalizers run: UI deregistration, watcher close), bounded by
shutdownGraceMs.
import { definePluginKit, serveUi } from "@punktfunk/plugin-kit";
import { Effect, Layer } from "effect";
export default definePluginKit({
name: "my-plugin",
version: "0.1.0",
layer: MyServices.layer, // over the kit base: HostClient | PluginInfo
main: Effect.gen(function* () {
const engine = yield* MySync;
yield* engine.start;
yield* serveUi({ title: "My Plugin", icon: "puzzle", staticDir, api: MyApiLive });
yield* Effect.never;
}),
});

sseRoute |
the status SSE endpoint (httpapi has no event-stream media type) |
runPluginCli |
<bin> <command> dispatcher reusing the plugin's layer graph (deliberately not effect/unstable/cli — that would drag platform packages into every plugin) |

Telling the host how to recognize a running title (detect)
A ProviderEntry may carry an optional detect hint:
{ external_id: "playnite:9f2…", title: "Hades",
launch: { kind: "command", value: "playnite://playnite/start/9f2…" },
detect: { install_dir: "D:\\Games\\Hades" } }
It is what lets the host tell that the game has exited — which ends the streaming session, so the player's client returns to its library instead of showing a bare desktop — and what lets an operator who opted into it end the game when the session ends.
Omit it and nothing breaks: the host tracks the process it spawns for your launch command. It matters
when that command hands off and exits — a launcher client, flatpak run, a front-end that starts
an emulator — because then there is nothing left for the host to watch, and both behaviors go quiet
for that title. Send whatever you genuinely know; install_dir is the one to send if you send only
one, since any process running from under it counts as the game. The host never lets a hint override
what it worked out itself, and never adopts a process that was already running before the launch.
Publishing
Tag plugin-kit-vX.Y.Z (matching package.json) — .gitea/workflows/plugin-kit-publish.yml
