To update after an intentional change, re-run bench/run.sh and replace the values, recording the reason in the commit body that ships the baseline bump.

At the 2026-05-28 kernel-extension-mechanics audit close, latency.explicit_at_rc.p99_us and latency.explicit_at_rc.p99_over_median were ALSO removed after a 6-invocation bencher characterisation found the explicit-arm p99 cv at 18.6% (vs implicit-arm cv 2.9%) with within-invocation 4-run spread up to 1.87x \u2014 structurally identical to the 2026-05-20 metric-removal precedent. The explicit-arm now gates only on median_us (which has cv 0.37% across 6 invocations, the actual allocator signal). The implicit-arm p99 / p99_over_median is kept because it is stable (cv 2.9%) and provides the contrast that lets future audits distinguish allocator regressions from machine jitter.",
