  "what": "No longer a library. Lucia was deprecated in March 2025 and now exists as a learning resource: a copy-paste <code>auth_session.ts</code> reference implementation plus The Auth Book, a free guide covering sessions, tokens and password handling. The site was last refreshed in July 2026.",
  "why": "Read it before choosing any vendor — it is the fastest way to genuinely understand what session auth does, and the single-file implementation is enough for small projects.",
  "warn": "Do not install the npm package for new work; it is unmaintained and will not receive security fixes. This is documentation and example code, not a supported dependency.",
