"reporting, and clean cancellation (post-cancel enqueues refused, "
"pending discarded and counted). The rune serve surface /v1/events "
"(SSE) gains the same bounded-queue semantics natively (stdlib-only "
"mirror in src/go/rune-entry): overflow counts, honest queue-state "
"comments on the stream, and a retention cap on the ?last=N replay "
"with an honest gap comment when history beyond retention is "
