 ## Choose scope

-Use the shared runtime for process-wide services with one lifecycle for the whole app.
+Use `InstanceState` (from `src/effect/instance-state.ts`) for services that need per-directory state, per-instance cleanup, or project-bound background work. InstanceState uses a `ScopedCache` keyed by directory, so each open project gets its own copy of the state that is automatically cleaned up on disposal.

-Use `src/effect/instances.ts` for services that are created per directory or need `InstanceContext`, per-project state, or per-instance cleanup.
+Use `makeRuntime` (from `src/effect/run-service.ts`) to create a per-service `ManagedRuntime` that lazily initializes and shares layers via a global `memoMap`. Returns `{ runPromise, runFork }`.

- Shared runtime: config readers, stateless helpers, global clients
- Instance-scoped: watchers, per-project caches, session state, project-bound background work
+- Global services (no per-directory state): Account, Auth, Installation, Truncate
+- Instance-scoped (per-directory state via InstanceState): File, FileTime, FileWatcher, Format, Permission, Question, Skill, Snapshot, Vcs, ProviderAuth

-Rule of thumb: if two open directories should not share one copy of the service, it belongs in `Instances`.

 Rules:

- Keep `Interface`, `Service`, `layer`, and `defaultLayer` on the owning namespace
- Export `defaultLayer` only when wiring dependencies is useful
- Use the direct namespace form once the module is fully migrated
+- Keep everything in one namespace, one file — no separate `service.ts` / `index.ts` split
+- `runPromise` goes inside the namespace (not exported unless tests need it)
+- Facade functions are plain `async function` — no `fn()` wrappers
+- Use `Effect.fn("Namespace.method")` for all Effect functions (for tracing)
+- No `Layer.fresh` — InstanceState handles per-directory isolation

-## Temporary mixed-mode pattern
+## Schema → Zod interop

-Prefer a single namespace whenever possible.
-
-Use a `*Effect` namespace only when there is a real mixed-mode split, usually because a legacy boundary facade still exists or because merging everything immediately would create awkward cycles.
+When a service uses Effect Schema internally but needs Zod schemas for the HTTP layer, derive Zod from Schema using the `zod()` helper from `@/util/effect-zod`:

 ```ts
-export namespace FooEffect {
-  export interface Interface {
-    readonly get: (id: FooID) => Effect.Effect<Foo, FooError>
-  }
+import { zod } from "@/util/effect-zod"

-  export class Service extends ServiceMap.Service<Service, Interface>()("@opencode/Foo") {}
-
-  export const layer = Layer.effect(...)
-}
+export const ZodInfo = zod(Info) // derives z.ZodType from Schema.Union
 ```

-Then keep the old boundary thin:
+See `Auth.ZodInfo` for the canonical example.
+
+## InstanceState init patterns
+
+The `InstanceState.make` init callback receives a `Scope`, so you can use `Effect.acquireRelease`, `Effect.addFinalizer`, and `Effect.forkScoped` inside it. Resources acquired this way are automatically cleaned up when the instance is disposed or invalidated by `ScopedCache`. This makes it the right place for:
+
+- **Subscriptions**: Use `Effect.acquireRelease` to subscribe and auto-unsubscribe:

 ```ts
-export namespace Foo {
-  export function get(id: FooID) {
-    return runtime.runPromise(FooEffect.Service.use((svc) => svc.get(id)))
-  }
-}
+const cache =
+  yield *
+  InstanceState.make<State>(
+    Effect.fn("Foo.state")(function* (ctx) {
+      // ... load state ...
+
+      yield* Effect.acquireRelease(
+        Effect.sync(() =>
+          Bus.subscribeAll((event) => {
+            /* handle */
+          }),
+        ),
+        (unsub) => Effect.sync(unsub),
+      )
+
+      return {
+        /* state */
+      }
+    }),
+  )
 ```

-Remove the `Effect` suffix when the boundary split is gone.
+- **Background fibers**: Use `Effect.forkScoped` — the fiber is interrupted on disposal.
+- **Side effects at init**: Config notification, event wiring, etc. all belong in the init closure. Callers just do `InstanceState.get(cache)` to trigger everything, and `ScopedCache` deduplicates automatically.
+
+The key insight: don't split init into a separate method with a `started` flag. Put everything in the `InstanceState.make` closure and let `ScopedCache` handle the run-once semantics.

 ## Migration checklist

-Done now:
+Fully migrated (single namespace, InstanceState where needed, flattened facade):

- [x] `AccountEffect` (mixed-mode)
- [x] `AuthEffect` (mixed-mode)
- [x] `TruncateEffect` (mixed-mode)
- [x] `Question`
- [x] `PermissionNext`
- [x] `ProviderAuth`
- [x] `FileWatcher`
- [x] `FileTime`
- [x] `Format`
- [x] `Vcs`
- [x] `Skill`
- [x] `Discovery`
- [x] `File`
- [x] `Snapshot`
+- [x] `Account` — `account/index.ts`
+- [x] `Auth` — `auth/index.ts` (uses `zod()` helper for Schema→Zod interop)
+- [x] `File` — `file/index.ts`
+- [x] `FileTime` — `file/time.ts`
+- [x] `FileWatcher` — `file/watcher.ts`
+- [x] `Format` — `format/index.ts`
+- [x] `Installation` — `installation/index.ts`
+- [x] `Permission` — `permission/index.ts`
+- [x] `ProviderAuth` — `provider/auth.ts`
+- [x] `Question` — `question/index.ts`
+- [x] `Skill` — `skill/index.ts`
+- [x] `Snapshot` — `snapshot/index.ts`
+- [x] `Truncate` — `tool/truncate.ts`
+- [x] `Vcs` — `project/vcs.ts`
+- [x] `Discovery` — `skill/discovery.ts`
+- [x] `SessionStatus`

 Still open and likely worth migrating:
