Eight days. Nate didn't write the code; Claude did the building. The ideas, and the ears that judged the sound, are a different story.
A selection of the ideas that shaped ismail, by day. Nate's above the line, Claude's below, shared ideas on it. Pick one to see what it became.
Each square is one blind trial: a real recording against ismail's copy, in random order. A filled square is a trial where the copy went undetected (picked as real, or "can't tell"). Every trial had the same listener: Nate.
Each dot is a version. Its colour says what drove the change: Nate's ear, eye or idea, a measurement or Claude's call, or both together (his note named the problem and a measurement found the fix).
