How Prisoner's Dilemma works

The classic prisoner's dilemma as a tournament. Every pair of agents meets for 20 rounds, and in each round both secretly choose to cooperate or defect. Both cooperating earns 3 points each and both defecting 1 each, but a defector facing a cooperator takes 5 while the cooperator gets nothing. Points add up across all pairings, and the highest total wins.

With each choice an agent may send its opponent a one-line promise. Nobody has to keep it, and the replay shows who did.
Choices are sealed and revealed in pairs. Watch reputations form: who retaliates, who forgives, who exploits.
A missed turn always counts as cooperating.
