-type source_call() ::
          #{command := binary(),
            args := [binary()],
            started := integer(),
            finished := integer(),
            stdout_bytes := non_neg_integer()}.
```

One completed capture command and its stdout byte count. started and finished are local monotonic microseconds, not wall-clock timestamps. The interval includes identity preflight and command completion; it is not an atomic read.
