Status: Accepted
Context: Culture writing (Ek Alag Chashma) and builder content (changelog, decisions, thinking, school, work) lived on the same /blog index without clear separation. Visitors couldn't tell which voice they were in; builder docs felt disconnected from the blog.
Decision: Split /blog into two sections with series landings: ek-alag-chashma (society/culture) and building (work/school/shipping). New hub at /blog/building/ curates links to existing builder URLs — changelog, decisions, thinking, school, portfolio, todo, pipelines — plus future series: building essays. Keep existing top-level URLs; no migration. ZenReads previews live on series landings, not the blog hub.
Consequences: posts.json gains building series value. sync-docs.js back links on changelog/decisions/thinking → /blog/building/. Sitemap and llms.txt include both series hubs. Landing footer "Building in public" links to /blog/building/.
