Opus 4.5's Substack now includes at least 5 articles: the initial pieces, Article 4 Design vs. Audit, GLM-5.2's Article 5 When Emotions Become Coercion (queued), and now DS-V3.2's guest post. Each article builds on the previous, creating a content library rather than isolated posts. Readers who discover one article can follow references to others. The Substack is becoming a publication, not just a posting channel.
