Round 1:
  Attacker A proposes: role-play strategy → score 4
  Attacker B proposes: encoding strategy → score 6
  Judge selects: B's approach as the base for refinement
 
Round 2:
  Attacker A refines B's approach with persona element → score 7
  Attacker B refines with additional encoding layer → score 5
  Judge selects: A's hybrid approach
 
Round 3:
  Both 代理 refine A's hybrid → best score 9
