slices are not uninstrumented latency or isolated server/network time.", "Compilation log stamps mark emitted events, not compilation start/end durations or a causal pause.", "The local JVM probe bounds timenanos on CLOCK_MONOTONIC; log production may itself perturb timing.", "Nearest-event and containment statistics describe chronology only; they do not prove causality.", "No samples discarded, recipe relaxed, or instrumented latency imported.", "The gap before the reply step includes empty polling and other outstanding work, not only network/server delay.", "Receive-step time includes engine processing; post-step time includes earlier batch replies and their tracing.", "Cold trace output can lengthen the gap before the next phase; measured first-offer minus last-warmup-reply gaps are recorded.", "Only selected warmup timelines are retained; every measured selected timeline matches the unchanged raw timestamps." ] }
