/* Binary TX only; no broker/HTTPD queries, heap scans, or sensitive identities.
* queued_* counts transport reservations, including reported queue failures;
* sent_* counts successful send-call returns. send_errors includes owner-context
* rejection; send_call timings count only actual API calls. queue_wait includes
* owned callbacks retired without sending. Pending age is since reservation-path
* entry, including an executing send; unavailable epochs are explicitly marked.
* All timing endpoints are local monotonic estimates, never peer acknowledgments.
* Disable freezes aggregates; enable resumes them. Every toggle/clear fences
* in-flight samples. Clear preserves enabled state. Epoch exhaustion fails closed.
* Nonempty completion intervals include idle; first_nonempty requires the first
* subsequent read to return data (not proof of backlog at send completion). */
