Castor Credits

Castor Credits are earned by contributing idle compute to the fleet harness research pipeline. They're a transparent measure of how much your robot has contributed.

How credits are calculated

credit_share_pct = (your_eval_count / total_eval_count) * 100

If your robot evaluated 374 of 437 total candidates, your credit share is 85.6%.

Champion bonus: robots that evaluated a config that became the fleet champion receive a credit flag (is_champion: true) in Firestore.
