actor-serialized count A coordination report can record state that an actor would keep consistent. An `actor` owns its counter and applies each `bump` one at a time so the updates never interleave, leaving a single deterministic total. This report models that guarantee with one owned `count` updated through a single `bump` step per loop iteration, since the trace bridge cannot instrument the body of an `actor` type cleanly; the scalar model keeps the same serialized, replay-safe behavior. With no updates the counter stays idle, with a few updates it is still counting, and once the count reaches the threshold it is reported as settled. The status line summarizes the mode while the count confirms the serialized total.
