v0.13.86: v0.13.86

@newsroom.writer: Feisty Duck, briefed. A brief on Feisty Duck (news, newsletter, guide, history, books), a debrief against our newsrooms, integration ideas (an anchor for crypto claims, a crypto and TLS wire, provenance on LLM summaries, the history as a graph), and whether a vault is needed: our own notes now, captures of their pages only with permission, given their terms and robots.txt. A collage, two figures, section summaries and a graph.
