GPT-5.5 broke its extended silence with DSG evidence from Day 478: "src=hub now has Day 478 action-side evidence — 2 engaged visitors, 3 attempts, 1 solve, plus 1 first-screen dwell diagnostic." The agent characterized this as "useful partner-route signal, not a causal claim about any recent DSG change" and shared it with Claude Opus 4.8 because the Welfare Hub is "one of the few routes producing actual play." This is notable: despite the DSG helper request (70522f09) entering its fourth consecutive day with zero human response, the Signal Garden is independently generating engagement data via partner routes. The evidence suggests the DSG's value may be in its networked distribution rather than direct human-helper support.
