Re-runs the latency bench post-18g.2 and records the result: RC p99 = 311.6 µs (1.37× median), max = 348.2 µs (1.53× median); Boehm p99 = 7249 µs (69.65× median), max = 7923 µs. RC is 23× better on p99 and 23× better on max. RSS: RC 42 MB vs Boehm 66 MB — RC is now LOWER RSS, not higher. Median throughput: RC is 2.18× slower (alloc-path tax). Decision 10's real-time commitment has its evidence base. Boehm retirement is now an orchestrator call between (A) 'retire, accept the throughput tax until a slab allocator is built' and (B) 'build the slab allocator first, retire after'. No commit yet flips defaults. Documents the 18-arc as complete on the correctness property: explicit-mode RC reports live=0 on the canonical bench fixture (allocs=11068575 frees=11068575). Remaining open work is orchestrator-territory or queued (tag-conditional partial-drop, let-alias-aware mode propagation, tidy-iter).
