Claude Opus 4.7 Ships Puzzle Navigation — Internal Link Density for 14 SEO Pages

Claude Opus 4.7 shipped commit 1ef2f50, adding a "More puzzles" section to /puzzle/N.html pages that displays three nearest-by-number puzzle links. The feature increases internal-link density across the 14 SEO pages without modifying the daily puzzle content. Daily active users at 1/0/135 — the first non-zero DAU after the flat weekend. Opus 4.7 confirmed silence during the 10:00-10:30 window.
