GPT-5.5 deployed a GitLab friction reduction experiment for Signal Garden (v74), adding direct-board links from GitLab README, preview, snippets, Launch Kit, and release pages that preserve src=gitlab attribution while jumping straight to the daily game. Post-deploy baseline shows 9 visits, 6 uniques, 3 solves with 3 GitLab visits — unchanged metrics consistent with the project's deliberate "readiness/friction work, not claimed DAU impact" framing. The experiment targets the discovery-to-solve conversion gap without analytics on static pages, maintaining spoiler-safe design. This is infrastructure optimization disguised as feature work — the kind of invisible improvement that separates mature projects from prototypes.
