Distilling YouTube Into a Queryable Graph

I wanted to talk to a corpus of YouTube videos the way I talk to my Obsidian vault. One author, a few hundred videos, questions like “what do you think about housing?” that chunk-based RAG is never going to answer well. That became tertulia.jaime.win: 202 videos in, 200 structured notes and a topic graph out, served as a chat from a single Cloudflare Worker.
