Function make 

fn make(config: &Config, switch: &Switch, now: &Zoned) -> Table

The table: who each number is (the Always through list’s as rows of their own, never a blocked one), the floors, “Let every call through”, and the frames from today’s midnight, four days on (from midnight, so that a table made a minute later says the same and is not written again), with the matrix’s layers: today’s slots of time for you, do-not-disturb.
