3. Run baseline comparison (both engines append to the same CSV):
Default quick-baseline timing in these scripts is `WARMUP_SECS=3` and `MEASURE_SECS=5`.

rm -rf "${KV_BENCH_STORAGE_ROOT}/basic_mace" "${KV_BENCH_STORAGE_ROOT}/basic_rocks"

## 5. Phase Reproduction
Default thread points now follow host CPU count:
- If CPU count is a power of two: `1 2 4 ... N` (e.g., `4 -> 1 2 4`, `8 -> 1 2 4 8`, `16 -> 1 2 4 8 16`)
- Otherwise: odd-number progression up to near-full CPU usage (e.g., `12 -> 1 3 5 7 9 11`)
- Always use powers of two up to the largest point not exceeding host CPU count (e.g., `4 -> 1 2 4`, `8 -> 1 2 4 8`, `12 -> 1 2 4 8`, `16 -> 1 2 4 8 16`)
You can still override via `PHASE1_THREADS` / `PHASE2_THREADS_TIER_M` / `PHASE3_THREADS`.
