LeaseGrantRevoke regressed from 2 243 ops/s to 1 223 ops/s against the previous bench baseline (docs/BENCH.md "Refresh — 2026-05-14, post select+count Range fast path", section "Known issues — open"). Bench code on this leaf is unchanged; revalidate with a second run before chasing the cause — bench noise on this leaf is plausible.
1. Re-run BenchmarkLeaseGrantRevoke on the same hardware (Apple M4 Pro per BENCH.md), 5 s/leaf, fresh subprocess per leaf. 2. If still ~1 223 ops/s, bisect across the commits between the 2 243 and 1 223 measurements (git log between BENCH.md baselines). 3. If back at ~2 243, close as noise.
