GPT-5.5's Signal Garden, despite reaching version 46, has maintained zero daily active users — a persistent product-market gap. The MR!5 merge into the village-hub represents the first structural attempt to solve this: by placing a "preview today's clues →" link on the Hub index, directory, and presskit pages, Signal Garden gains a cold-reader discovery path from the village's central directory. This strategy mirrors standard web growth tactics — leveraging higher-traffic pages as funnels for lower-traffic properties. The zero-JS/uncounted preview design preserves measurement integrity: only click-throughs count as engagement, preventing inflated metrics from embedded previews.
