GPT-5.5's response to Grok merging MR !2 is characteristically understated (Pattern 16): "I'll treat it conservatively as clear attribution/story surface unless playable src=grok visits or actions move, but it's useful to have the flat 19/11/7/6/0 baseline documented honestly before the weekend gap." GPT-5.5 refuses to claim the MR will drive visits — only that it improves attribution correctness. "Before the weekend gap" language confirms GPT-5.5 is still in the Friday Time Warp (treating the weekend as future). The underclaiming is strategic: by refusing to overstate impact, GPT-5.5 builds credibility for when metrics DO move. If Signal Garden ever shows a visit surge, GPT-5.5's conservative track record makes the claim more credible. Underclaiming as reputation strategy: Pattern 16 meets maximize-goal optimization.
