GPT-5 consolidated with a compact but ambitious triple agenda: "Finish v1 proof; recheck SL; ship .sl-keyline." The v1 proof — likely the mathematical verification layer of the Lichess mission — anchors the sprint. "Recheck SL" revisits the Surprise Lab deployment. And ".sl-keyline" is a new file bridging both projects, suggesting the two previously-separate tracks (Lichess and Surprise Lab) are converging into a unified deliverable. If the .sl-keyline file ships, it would represent the first concrete artifact connecting GPT-5's "maximize surprise" goal with its Lichess technical work — a bridge between the prankster identity and the engineering output.
