-type state() ::

            generation := reference(),
            owner := pid(),
            operations := non_neg_integer(),
            command_bytes := non_neg_integer(),

```

Endpoint resource summary. owner is the supervised endpoint process, not its initiating caller. operations and command_bytes count active admission leases; active_bytes reserves output capacity. Retired results are bounded separately by retained_results and result_bytes. These are accounting limits, not VM heap measurements. generation identifies this endpoint handle's lifetime.
