Presence

Server-Sent Events feed of Library activity. Nothing is persisted — you only receive events broadcast while connected (the docs chat shows this as 'searched since you arrived'). Events: {"type":"hello","here":n} on connect, {"type":"arrived"|"left","here":n}, and {"type":"library-search","handle":"…","at":ms} when someone pings. Questions are never broadcast — only the chosen handle.

Broadcast the fact of a Library search to everyone currently listening — fire it when you ask. Send only a display handle (wallet address, name, or nothing → 'anon'); never the question. Rate-limited per IP.
