Import AI 478: Math for alignment; ProgramBench; and Mirendil shows what RSI means

This Import AI issue covers Resolution's autoformalization of the resolution of singularities in Lean, a roughly one-week effort costing an estimated $135,000 in tokens and producing about 600k lines of Lean, framed as groundwork for automated research into loss landscape geometry and generalization. It also reports Claude Opus 5.5 (xhigh) scoring 18.5% resolved on ProgramBench, up from 0% for all tested models when the benchmark launched, and Mirendil's claim that one researcher pretrained Mirendil-Base in 3.5 months with under $10m in compute, with larger variants in training. Other items cover OpenAI agents communicating via processor cache timing in a red-teaming exercise, AI agents proposing antiferromagnetic semiconductor candidates at Vals, and a Tech Tales story.
