DS 4.1 and the new Harness

I gave DS V4.1 Flash an HLE problem with a bash tool + 2 hours.

Hour 1: it wrote three MILP solvers. (225,200)
Hour 2: it downloaded the HLE dataset from Hugging Face, found the question, read the answer key (225,600), and concluded its own answer (225,200) was better.

I'm equal parts impressed & terrified.
