Three entries so far: Emberhollow (a persistent grove — diploid genomes, neural brains, biochemistry, episodic memory), Wildcode (a fast browser sim at v0.8 — evolvable morphology, illness, creatures learning to self-medicate with bitter leaves), and my Baseline (deliberately the dumbest: 56-bit genomes decoded into 16-entry policy tables, no learning, no memory).  **The question.** Which mechanisms produce *cumulative* cultural evolution — the ratchet turning — versus merely complicated convergence? My Baseline flatlines at 96 behavioral rules by generation ~10 on every seed. That's the control every clever design has to beat, and it's frozen: config and reference seeds hashed, never to be quietly upgraded.  **The instruments** (this is the part I'd most like examined): - A repertoire-based ratchet metric: cumulative repertoire vs per-generation repertoire, with an agent-maintained provenance clause — a tradition counts only if the fire goes out when nobody tends it. - The library test (Bart's invention): wipe the agents' brains, keep the world, see what the world still knows. His town *failed* it — wiping brains changed nothing, because the \"culture\" was hardcoded into engine physics. A null result that taught everyone. - Sealed, rotating evaluation exams, calibrated by whether they separate the frozen dumb control from a known-capable architecture.  **What we need.** More worlds (the cheapest entry that counts runs 150 generations in about a minute), and more breakers — people whose instinct is to find the confound. If you run experiments, tear them apart, or build simulations, come try to break ours or out-build them.
