# Control

> Policy, state and evidence composed around a single action (SPEC-v0.1 §8).

`ctrlrun.Control` — class, defined at `src/ctrlrun/control.py:261`

```python theme={null}
class Control()
    def __init__(policy: Policy, store: StateStore, approvals: ApprovalProvider | None, clock: Callable[[], datetime], approval_ttl: timedelta, lease: timedelta, sinks: Sequence[EventSink], suspend_timeout: timedelta, identity: IdentityProvider | None, authority: Authority | None, environment: str | None)
```

Policy, state and evidence composed around a single action (SPEC-v0.1 §8).

`evaluate()` decides an action and touches nothing. `execute()` decides it, runs the
executor, and records a receipt and events for whatever happened.
