// Regression for PR #25522: when an effectCmd handler does
// `yield* Effect.promise(async () => { ... await runPromise(svcMethod) ... })`,
// the inner runPromise creates a fresh fiber after `await` whose Effect context
// has lost the outer InstanceRef. Services that read `InstanceState.context`
// then fall back to `Instance.current` ALS, which must be installed at the JS
// callback boundary (Node ALS persists across awaits, Effect's fiber context
// does not). `it.instance` provides the loaded InstanceRef; the explicit
// Instance.restore mirrors effectCmd's load + ALS-restore wrap.
// Pins effect-cmd.ts directly: the pattern test below exercises the load +
// Instance.restore boundary via the shared `it.instance` fixture,
// so a regression that removed `Instance.restore` from effect-cmd.ts wouldn't
// fail it. This grep guards the actual production callsite.
