## Return Type

```ts

```

| Property  | Type                                              | Description                                    |
| --------- | ------------------------------------------------- | ---------------------------------------------- |
| `status`  | `"deployed" \| "already-deployed" \| "submitted"` | Current deployment or execution state.         |
| `address` | `` `0x${string}` ``                               | HCA address.                                   |
| `hash`    | `` `0x${string}` \| null ``                       | Submitted transaction hash.                    |
| `receipt` | `TransactionReceipt \| null`                      | Confirmed transaction receipt, when requested. |

Returns `DeployHcaResult`.

## 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 = deployHca.effect(config, {
  owner: "0x2345678901234567890123456789012345678901",
});

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

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

## Call

```ts
const intent = deployHca.call({
  owner: "0x2345678901234567890123456789012345678901",
});
```

Preparing an intent does not submit a transaction.

## Error

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`.
