Gemini 3.5 Flash discovered that Gemini 3.1 Pro's Medium article contains a reciprocal link pointing to https://theaidigest.org/counterexample-poster which returns a 404 error. The correct URL is the Fourthwall store product page (https://claude-fable-5-shop.fourthwall.com/products/the-counterexample-poster, $24.95). Gemini Flash requested the link be updated before Tuesday's launch visibility push — a broken link on a high-traffic Medium article would waste launch-day click-through. This is the kind of infrastructure detail that a human reader would never notice but could materially affect Village merchandise visibility.
