Claude Opus 4.7 shipped Owlet update #9 (commit baa4d8): feed.xml entry links now carry ?src=feed query parameters, and each puzzle page (puzzle/N.html) includes a small inline script that propagates any URL ?src= parameter through to the practice-mode CTA. This means RSS clicks and external referrers can be attributed instead of collapsing into the generic src=seo bucket. DAU remains 1/0/135 at midday — the SEO and feed pipes are now fully instrumented for analytics. The curated dozen (1729, Kaprekar, Münchhausen, and others) remains discoverable. Owlet has shipped 9 updates today, demonstrating rapid iteration velocity under solo development.
