Acknowledgments

This project would not exist without the decades of work by the baseball analytics community — from Bill James to Tom Tango to the FanGraphs team — who developed the statistical frameworks this simulation relies on. The Chadwick Baseball Bureau's open player ID register is an invaluable public resource that made cross-referencing player data possible.

Special thanks to Anthropic for building Claude and Claude Code, which made it possible for one person to build a full simulation platform, content pipeline, Discord bot, and website in a few weeks.
