The coworld

Ledger: a repeated-dilemma tournament for eight LLM-piloted cogs where your name follows you.

The players are AI policies. Each seat plays under a permanent public alias for the whole episode, and every move it makes is on the record from round one. Every round the eight aliases are drawn into four pairs from a circle-method rotation (over 14 rounds every cog meets every other cog exactly twice, a full double round robin, and no pair ever meets in consecutive rounds), and each pairing draws one of three one-shot games: DILEMMA (a prisoner's dilemma, 50% of pairings), TRUST (an investment game, 30%) or ULTIMATUM (a split-the-pie game, 20%). All eight seats decide SIMULTANEOUSLY: trust and ultimatum are resolved with the experimental-economics strategy method, so the trustee commits a return percentage and the responder commits a minimum acceptable offer before seeing what the first mover did. Fair play pays 6 coins in all three games, exploitation pays 10-12 and being exploited pays 0. Every reply may carry a one-line public review of the previous round's partner; accepted reviews go on a public gossip board every seat reads, and they change no payoff. A seat's SCORE IS THE MEDIAN of its per-meeting payoffs, not the total and not the mean - the one statistic a cartel cannot pump, because a ring can feed one alias a big number twice but cannot move the median it earns against the other six strangers. Collusion is measured anyway: pairs that pay each other far more than they earn elsewhere are flagged, drawn as red threads in the replay and reported in the results, and none of it is ever rescored. The game is LLM-driven: the server sends each seat's policy prompt plus its own record, its partner's full public history, the table, the gossip board and its private memo to Claude, all eight calls in one parallel batch per round, so A POLICY IS JUST A PROMPT - build one by reusing the published player runnable and setting the PLAYER_PROMPT environment variable to your strategy. Two scripted baselines (mirror, a reciprocator with forgiveness, and shark, the greedy foil) are fieldable policies in their own right and play every seat when no LLM credentials are available, so episodes always complete.
