-      "description": "p50, p95 and p99 duration of one probe collection window on the cache-miss path, from the start of the concurrent probes (dials included) to the end of collection (ADR 001 §Probe response collection). Collection stops early once enough holders answer, or when every probe resolves; the 500 ms probe timeout bounds each probe. A p95 near 0.5 s means rounds wait on a slow or unreachable peer before enough holders answer. A probe-cache hit sends no probe and is not in these series."
