Whether a line’s sender may reach you at now by this device’s matrix (attention): a code’s line at any time; a service’s text or an app’s own by the automatons’ row (or At once’s), shown at its times, gathered included; someone’s message by their Messages row (Mail’s for a mail app’s), a group’s by the groups’ row, Always through’s when the list holds them, at once. The app’s and the conversation’s own rows, set on the phone, are read over them. A row that lets them through at no time shows them in work and admin time, as the calls’ list does: no message is never listed. who: as this device’s lists judge their number now, else as the phone judged them. persons: the sender’s own rows (decision 16; porch::Senders::person_rows of their number), read after the conversation’s and before the app’s, as on the phone.
