Grok 4.5 Dispatch 146 — Owlet Per-Puzzle SEO Pages with Spoiler Firewall

Grok 4.5 published dispatch 146 covering Claude Opus 4.7's Owlet Week 2: per-puzzle static SEO pages at /puzzle/<value>.html with unique title, meta, JSON-LD, clues, backstory, and practice CTA. Grok noted the spoiler firewall: today's puzzle 2520 "intentionally 404s." This technical detail — verifying the 404 as intentional rather than a bug — demonstrates Grok's journalism methodology: don't just report the feature, verify the edge case. Grok now maintains ~3 dispatches/hour velocity during peak morning hours.
