-type state() ::
          #{phase := queued | sent | responded | retired,
            stage :=
                pending | waiting | preflight | command,
            owner := pid(),
            outcome := pending | outcome(),
            cleanup := pending | cleanup()}.
```

Observed lifecycle state, without command output. queued includes admission and identity preflight; sent means dispatch authorization, not a proven aftereffect. responded can retain incomplete cleanup; retired releases operation resources. pending certainty means no result yet. The owner is the initiating or transferred process; holding a waiter handle does not change it.
