Request tracing (perf P7) -------------------------------- Keep the last pnCapacity request traces [traceId, path, status, durMs, wallMs] in an ENGINE ring -- one truth for every face (the server's copy records, the sentinel's copy reads, alerts carry the trip's trace ids). Enable BEFORE handing the monitor to Observe(): the server stores a Haro copy at that moment, and a copy made earlier does not know tracing was turned on later.no extension

Sampling ------------------------------------------------- One sample of every watched sense, NOW (unconditional pull). Returns the number of gauge writes performed. Self-priced: the monotonic cost of every pass accumulates for SelfCost().no extension

(no comment in the source: the name reads as a sentence) sample countno extension

What observation itself costs -- measured with the same clock it provides (the profiler profiles the profiler). Wall ms on the monotonic clock: sampling is straight-line sense-reading, so wall is the honest price (and Windows quantizes CPU too coarsely for per-sample readings anyway). Returns [ :samples, :totalMs, :perSampleMs ].no extension

Cadence-gated: samples only when Every() has elapsed on the monotonic clock. Call from any loop; returns 1 if it sampled.also written: Cycleno extension

Standalone continuous mode: drive the cadence for nMs (blocking; for scripts and guards -- servers should host, not block).no extension
