 The router itself saturates one core at about 300–450 tool calls per second, so 4–6 workers is the useful range.
 
+On a private Space (`scripts/deploy_space.py`: cpu-upgrade, 8 vCPU / 32 GB, 4 workers × 48 sessions, the full

+|---|---|---|---|
+| Tools, 192 concurrent | 575/576 ok | 643 episodes/min, 110 calls/s | 0.26 / 0.8 s |

+- The one failure arrived at the capacity edge, just before a closing session was freed.
+- At capacity, cold resets take 7–10 s; each new design is fetched once.
+- More than 192 sessions are refused cleanly ("Server at capacity") after every worker has been tried.
+- OpenEnv's client has no option for auth headers. `scripts/loadtest.py --hf-token-env HF_TOKEN` shows the two
