An agent chat will act on a machine you choose, so this is the screen where you choose it. User-owned like a note, not admin-owned like a connection: these are somebody's own machines and somebody's own keys, and "anyone in this group may log in to my server" is a different feature with a different blast radius. services/sharing.py is deliberately not involved either -- sharing grants reading, and a host somebody else can read is a host they can log in to. Trust on first use, made explicit rather than assumed. Adding a host does not connect to it. Check looks at its key and shows you the fingerprint; nothing is sent until you accept, because get_server_host_key completes the key exchange and stops -- no username, no credential. Accepting pins it, and a host that later presents a different key is refused with the reason rather than quietly trusted. Moving a profile to another host or port forgets the pin, since a key belongs to the machine it came from. Four asyncssh defaults are actively wrong here and all four are passed explicitly: every LLeMbas user shares one unix account, so `known_hosts` would be a shared trust store, `client_keys` would authenticate one person with another's key, `config` would let a ProxyCommand redirect the connection, and `agent_path` would silently use $SSH_AUTH_SOCK. There is a test for exactly that, and it needs no server. Files go over SFTP rather than through a shell. The SSH exec protocol carries one command *string* that the far side parses, with no argv form at all, so a model-supplied path in a command line is unavoidably a quoting problem. Over SFTP a path is a path. Chat gains its kind, connection, project directory and mode; the first three are fixed once a chat has a message, because a transcript whose earlier turns ran somewhere else is not one conversation.
