- No switching headsets (or changing the active one's user/port, or removing it) while installs run: they read the ssh settings step by step. - Switching reroutes every command to the new headset at once, even if it never answers. - ~/.ssh/config edits are serialized, use unique temp files, and back off if another program wrote the file meanwhile. - stop() ends a handshake in progress and joins the connector. - Pinned keys are written unhashed (HashKnownHosts=no); hashed ones are still found and forgotten via ssh-keygen. - Set Up Connection changing a headset's user or port updates the registry.
