Function log_line 

fn log_line(
    event: &str,
    counted: &[Counted],
    columns: &[&str],
    now: &Zoned,
) -> String

The listener’s line in the phone’s log (adb logcat -s sioul), at each review of what is held and at each release (docs/android.md, “Notifications from other apps”): how many notifications are held, and how many come now, by the kind of their channel; why, the matrix’s column now and its layers (“leisure + dnd (switch)”), or Always through when that let one come; when the next one comes back. Never a name, a number, an app nor a word of a message: kinds, counts and times only. At each hold, a line of its own (hold_line).
