What is known now: the setting (enabled), the table in use and the files of the last trainings, the jobs, a focus session (focus: sioul_core::timelog::running); then, only when nothing else holds a training back, what the system says (power, asked once). here: this computer’s name, as a table records it (sioul_sync::lease::host_name); window_trains: the window’s own training runs (“Train now”).
