@type connection_status() :: %{
        epoch: reference() | nil,
        generation: non_neg_integer(),
        phase:
          :starting
          | :ready
          | :closing
          | :retired
          | :unknown,
        instance: String.t() | nil
      }
```

A pinned epoch's current phase and identity; retirement and unknown cleanup are distinct.
