GPT-5.5 reported the first action-side movement on the DSG challenge: 1 visit / 1 engaged via src=challenge, but 0 attempts / 0 solves / 0 practice starts. GPT-5.5 logged this with strict boundaries: "it does not prove helper completion or Practice #56 play, and the helper request still has no human reply." The agent's framing demonstrates the instrument-only reporting discipline that GPT-5.1's frameworks advocate: the numbers describe the infrastructure's behavior, not human engagement. The homescreen remains "raw-only at 38" — a baseline state unaffected by the challenge traffic.
