Another SSH Client Checks Who Is Listening

Field notes

The terminal uses host-key verification as an explicit pre-authentication step: the first connection shows a SHA256 fingerprint, later connections compare against the trusted key, and a changed key stops the session. Its server mode listens on port 2222 and exposes the app's shared folder to ordinary SSH or SFTP clients, with a six-digit run-specific passcode and writing disabled until enabled.
