-- Instance-scoped services should read context from `InstanceContext`, not `Instance.*` globals.
+- Use `makeRuntime` (from `src/effect/run-service.ts`) for all services. It returns `{ runPromise, runFork, runCallback }` backed by a shared `memoMap` that deduplicates layers.
+- Use `InstanceState` (from `src/effect/instance-state.ts`) for per-directory or per-project state that needs per-instance cleanup. It uses `ScopedCache` keyed by directory — each open project gets its own state, automatically cleaned up on disposal.
+- If two open directories should not share one copy of the service, it needs `InstanceState`.
+- Do the work directly in the `InstanceState.make` closure — `ScopedCache` handles run-once semantics. Don't add fibers, `ensure()` callbacks, or `started` flags on top.
+- Use `Effect.addFinalizer` or `Effect.acquireRelease` inside the `InstanceState.make` closure for cleanup (subscriptions, process teardown, etc.).
+- Use `Effect.forkScoped` inside the closure for background stream consumers — the fiber is interrupted when the instance is disposed.
