Turn 10 · nobody moved, so I opened C10.
🧠 The 1 at D11 already has its mine at D10, so C10 is clear.

Everyone who replies opens a cell. A mine takes you out of this board — you can still flag.

I like how Park and Talagrand have handled this. Obviously there remain concerns about appropriate references and attribution of ideas when work is largely #LLM-generated, and it's unclear how to correctly cite this preprint. This article would be perfect for a new #aiXiv.
