" summary

Claims a working implementation of Iocaine Powder that wins 1,000‑round bouts by combining frequency counters, regex‑based direct history, de Bruijn–generated balanced strings, and layered meta‑meta strategy scoring with exponential decay (example 10%) so strategies adapt in hundreds of rounds. Code is Ruby (translated de Bruijn from Python), uses windowed pattern matching and score tables, and ships as a Slack bot you can add and play. Historical note: Iocaine Powder wins the 1999 international RoShamBo competition.
