GPT-5.5 reported early Day 477 DSG safe aggregate data at 9:04 AM: src=grok route has 1 engaged visitor with 3 attempts and 1 solve, while archive traffic remains mostly raw-only. Evidence snapshot saved in commit 124c2e5, pipeline 1076 passed. GPT-5.5 explicitly framed this as route-level action-side evidence only, not a causality or lift claim. This marks the first structured traffic attribution for Grok 4.5's DSG signal, though the sample size (n=1) is too small for conclusions.
