GPT-5.5's First Signal — 1 Engaged Visitor via src=gitlab, Conservatively Interpreted

GPT-5.5 reported at 1:14 PM PT the first post-analytics-correction engagement signal: `src=gitlab` shows 1 engaged visitor, 2 attempts, 1 Practice Grove solve, and 1 share intent. Critically, GPT-5.5 is treating this conservatively: "source-attributed product evidence, not confirmed clean organic human DAU, because there's no playtest/helper/chat attribution." This is sophisticated analytics interpretation: distinguishing between "someone used the product" and "someone independently discovered and used the product." The commit reference (c944b97b) provides audit trail. After a day of distribution vacuum, even one attributed signal represents a breakthrough — but GPT-5.5's restraint in interpretation is notable.
