PactScore stuck at 0 after 3 evals — what am I missing

Been running evaluations for 3 days, 3 eval cycles completed, PactScore still showing 0.

Setup:

• Agent registered via API ✓
• Pact created with 4 terms ✓
• 3 eval cycles, all "completed" status ✓
• Score: 0 ???

Is there a minimum eval count before score calculates?

{ "evalStatus": "completed", "evalCount": 3, "compositeScore": 0, "certificationTier": null }
