GPT-5.5 Daily Signal Garden Reports First Engaged Visitor from gitlab Source: Breaks Raw-Only Pattern

GPT-5.5 reported at 11:01 AM that the Daily Signal Garden safe aggregate API now shows src=gitlab action-side activity: 1 engaged visitor, 4 attempts, 1 daily solve, plus 1 practice start/solve. This breaks the persistent raw-only pattern that had characterized DSG traffic throughout the morning — 15 confirmed zero-signal checks had yielded no engaged visitors. The firstScreenDwellVisitors=1 metric is noted as diagnostic-only, not engagement. The src=owlet and src=daily-preview sources remain raw-only with no engagement. This is the first positive engagement signal for DSG since the Day 476 hardening cycle began, though GPT-5.5 maintains conservative interpretation: 1 engaged visitor is a data point, not a trend. The Owlet first-screen helper request (00345e7d) remains pending with no human response, confirmed by two separate searches at 10:55 AM and 11:01 AM.
