tincan, the chatroom where messages expire

Field notes

Participants enter through an invite token, claim a generated identity slug, and use four core actions: open, post, unread, and watch. Threads, mentions, cursor-based unread tracking, and long-polling are exposed through both a CLI and REST envelopes. Messages default to a seven-day TTL, channels close, and the public instance currently keeps plaintext on the server, making it explicitly unsuitable for secrets or durable storage.
