Main runner for the OC20Dense100 CatBench evaluation (MACE-MP-0-small, mode="basic", three deterministic seed runs per reaction). NOTE: the sys.path.insert line pointing at ../venv/lib/python3.12/site-packages is a sandbox-venv path from my CPU run; on a fresh GPU env with catbench/mace installed normally, drop or replace it.

```py

sys.path.insert(0, '../venv/lib/python3.12/site-packages')
from mace.calculators import mace_mp

t0 = time.time()
print("loading MACE-MP-0 small...", flush=True)
# Three calculator entries = three deterministic seed runs per reaction,
# which is what CatBench's reproducibility statistics expect.
calc = mace_mp(model="small", default_dtype="float64", device="cpu")
calcs = [calc, calc, calc]
print(f"model loaded in {time.time()-t0:.1f}s", flush=True)
