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).
