From the workshop
Studio artifacts
Sketches, rules, characters and development notes. The games are the output; this is the working.
Training log
PPO v20 · 4,000 updates
19× faster than v19 on the 3090 — 4.6 hours instead of 34. It also collapsed. The batched-GPU rewrite and what the shortcut cost us.
Rules card
Sutda hand rankings
The nine Gwang, the Ttang, and why 3-8 beats a pair. Printed as a card you can keep open beside the game.
Character sheet
Sister Wendy, 12.4M games
She counts tiles. Commentary mode is a written voice, not a template — here is how she was drafted.
Method note
The Chair runs on live FRED
Expectations-augmented Phillips curve, two-to-three quarter policy lag. The papers are linked in the footer.
The Lab
Under the hood, it's not playing around.
The opponents are trained, not scripted. Here is the machine that does it.

What's being built right now.
Three things on the bench. Nothing here is announced until it works.
