6.6Multi-Round Convergence

The Critic-Actor loop typically converges in 2-3 rounds:

Round 1: Actor generates 30 tests
         Critic: 15 approved, 10 revise, 5 rejected
         Approval rate: 50%

Round 2: Actor revises 10, generates 5 new for gaps
         Critic: 25 approved, 5 revise, 0 rejected
         Approval rate: 83%

Round 3: Actor revises 5
         Critic: 29 approved, 1 revise, 0 rejected
         Approval rate: 97% → DONE

Why max_rounds matters: Without a limit, the Critic-Actor loop could iterate indefinitely, with the Critic finding increasingly minor issues. Set max_rounds=3 to balance quality and cost.
