pub fn take_bool2d_stats() -> (u64, u64)Expand description
Read + reset the 2D-path telemetry: (hosts cut via the 2D path, opening footprints subtracted in those hosts). Process-global; used by the perf harness to report the fast-path hit-rate. Relaxed atomics — a stale read under concurrency only mis-reports a diagnostic count, never geometry.
