- A second launch queued for the bus name instead of noticing the running copy, so two instances drove the controller. Request it with DoNotQueue. - Spawned commands are waited on by a reaper thread. - Config files are written 0600 with fsync; settings carry a version. - A settings file or profile that can't be read falls back to its .bak. - Importing a profile with command or key buttons asks before keeping them. - Test runs point the default profile at a fake port (SLIDEWIRE_DEFAULT_PORT).
