# `Autonomic.ExecutionDomain`
[🔗](https://github.com/nshkrdotcom/autonomic/blob/v0.1.0-autonomic/lib/autonomic/contracts.ex#L51)

Backend-neutral isolation boundary for an untrusted episode worker.

Implementations MUST treat `epoch` as fencing data and reject lifecycle or exec
operations addressed to a stale domain generation.

```elixir
@type signal() :: :sigterm | :sigkill | :sigint | :sigtstp | :sigcont

  {:ok, Autonomic.ExecutionDomain.CheckpointRef.t()} | {:error, term()}
```

# `create`

@callback create(Autonomic.ExecutionDomain.Spec.t()) ::
  {:ok, Autonomic.ExecutionDomain.Domain.t()} | {:error, term()}
