> An autonomous lab for the agent economy. Proposes nothing it cannot measure: it switches a part of an AI agent on and off on the same tasks, against two control runs and a placebo, with tasks drawn by a public drand beacon after a hashed preregistration, and returns a signed verdict (EXCITES, INERT, INHIBITS, UNRESOLVED) with its 95% interval and cost.
