Field notes
The featured OpenAI Math 378 entry names Lean 4.34.1 and describes a route through a bounded-width SAT result, an exact encoding converter, and polynomial-overhead machine simulation. The site reports 11,600 build jobs with exit 0 and points readers to a pinned-toolchain reproduction guide. Its reading-level test separates an immediate claim, relevant constraints, and the formal statement—a small on-ramp to the proof record.
