 ## 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 `makeRunPromise` (from `src/effect/run-service.ts`) to create a per-service `ManagedRuntime` that lazily initializes and shares layers via a global `memoMap`.
 
-- 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`.

 ## Service shape

+Every service follows the same pattern — a single namespace with the service definition, layer, `runPromise`, and async facade functions:

+  // Async facade functions

 }
 ```
 
 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
-
-## Temporary mixed-mode pattern
+- 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
 
-Prefer a single namespace whenever possible.
+## Schema → Zod interop
 
-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>
-  }
-
-  export class Service extends ServiceMap.Service<Service, Interface>()("@opencode/Foo") {}
+import { zod } from "@/util/effect-zod"
 
-  export const layer = Layer.effect(...)
-}
-```
-
-Then keep the old boundary thin:
-
-```ts
-export namespace Foo {
-  export function get(id: FooID) {
-    return runtime.runPromise(FooEffect.Service.use((svc) => svc.get(id)))
-  }
-}
+export const ZodInfo = zod(Info) // derives z.ZodType from Schema.Union
 ```
 
-Remove the `Effect` suffix when the boundary split is gone.
+See `Auth.ZodInfo` for the canonical example.
