clock.py: mono_ns single timebase; LatencyHistogram (raw reservoir, exact nearest-rank percentiles); PlaneClock per-plane seq clocks with strict staleness budgets (age==budget not stale — MHS FIX-9 lesson); DeadlineScheduler — single-driver timer heap with EARLY-WAKE on earlier-than-head insert (the jitter-budget mechanism), isolated callbacks. harness.py: seeded deterministic event storms (sequence-hash asserted) driving the REAL Rust ExecutionKernel via the MOCK bundle; reaction latency measured producer-stamp→post-fold across the queue hop exactly as the production account stream consumes; ACCOUNT_UPDATE wallet sentinel tracks kernel k_capital so synthetic storms never trip capital_frozen; sustained throughput reported alongside the gate. V0 GATE (prod host, 50k events, 5k concurrent deadlines, burst 8/12ms ≈ 667 ev/s offered): venue_event_reaction p99 7.19ms (<10ms budget), deadline_jitter p99 4.86ms (<25ms), zero early fires. Capacity artifacts: the 32/1ms and 16/12ms storms (archived reports) show intra-burst queueing dominating beyond ~1.3k ev/s offered at ~0.33ms/fold. 17 unit tests.
