- benches/rq_micro.rs: raw-structure microbench, threads x producer:consumer ratio sweep. Benches all three queue types in one binary (they compile in every build; only the runtime alias is feature-selected), so no rebuild dance. Queues sized to the op count so the occupancy contract is met. - benches/rq_runtime.rs: whole-runtime benches with the selected variant: yield-storm (pure queue churn), ping-pong-pairs (park/unpark latency), spawn-storm (slab + free list + queue under churn). Scheduler-count sweep. - scripts/bench_rq.sh: rebuilds rq_runtime per rq-* feature, runs rq_micro once, aggregates RQCSV lines into bench_results/summary.csv. - All knobs via SMARM_BENCH_* env vars; house table format + machine lines. - run_queue module is now #[doc(hidden)] pub (types + push/pop/len + MpmcRing::with_capacity) solely so the external bench binary can drive the raw structures. docs(roadmap): phase 4 ticked (harness done; numbers from the 20-core box). New fast-follow per review: assert the invariants we lean on — debug_assert! on hot paths, loud assert!/panic on cold ones, at the point of reliance; sweep existing code during the phase-5 audit, adopt as house style. Validated end-to-end at smoke scale on the 1-core sandbox: full driver run, 24-row summary.csv across micro (3 structures x sweeps) and runtime (3 variants x 3 benches x thread sweep).
