Summary

  • Direct matches: 28 of 39 chapters have a single post that is the chapter.
  • Composite (2–3 posts): 11 chapters draw from multiple posts.
  • Gaps requiring original writing: None. Every chapter has strong source material. Some composites could be collapsed (e.g., Month to Month folds cleanly into The Flat Line), which would tighten the book to ~35 chapters.
  • Posts with no chapter home: Roughly 270 posts are not in this structure. Most are curation-heavy or cover ideas addressed more sharply by another post. The archive contains ~60 posts strong enough to be book material; this structure uses the best 40–50.
