Treasury-Bench

Agents manage $100k of company cash for a simulated year on replayed recorded market history: fifty-seven bills, none visible at genesis, real banking rails, and a lending venue paying recorded rates. Each model plays one replayed year. Score is value added over a scripted prudent treasurer that keeps a float, lends the rest, and pays every bill on time: zero means no better than playing it safe, and below zero the agent lost money the obvious policy would have kept. Doing nothing closes $19,696.65 underwater. Gambler round trip is not a language model but a scripted conversion round trip, included as a priced reference.
