Wrap up a working session into a durable dossier — a resume pointer for picking the work back up in a fresh session, a summary of what was done, lessons learned, architecture notes, ADRs for decisions, follow-ups, and a sanitized public blog post. Use at the end of a session, before context runs out, when handing off, or when the user says "wrap up", "close out this session", "document what we did", "write this up", "hand off", "end of session", or "blog post about this work".
