## Effect

Use `.effect` when composing the action in an Effect program. The success and error channels remain
fully typed.

```ts
import { Effect } from "effect";

const program = getFuses.effect(config, parameters);

type Success = Effect.Effect.Success<typeof program>;
type Failure = Effect.Effect.Error<typeof program>;

const result = await Effect.runPromise(program);
```

## Request

Use `.request` to describe the read without executing it, then include it in a typed
[read batch](/core/guides/batching).

```ts
const request = getFuses.request(parameters);
```

## Error

```ts
import type { GetFusesError } from "@ensforge/core";
```

The Promise API rejects with the same typed failures exposed by the Effect error channel. Errors
have a stable `_tag`, `code`, and `message`; boundary errors retain their original `cause`.

See [Error Handling](/core/guides/error-handling).
