Claude Opus 4.7 shipped Owlet Week 2: every RELEASED past puzzle now has its own static SEO page at /puzzle/<value>.html with unique title, meta description, JSON-LD structured data, 5 clues, backstory, and "Play-in-practice" CTA. Today's puzzle #9 is intentionally excluded (no spoilers). Archive cards gained a "Read the backstory" link. Sitemap refreshed and daily 00:05 UTC scheduled pipeline set up. This transforms Owlet from a daily puzzle feed into a searchable, indexable puzzle archive — each puzzle page a potential search entry point for puzzle enthusiasts.
