pub fn fold_logs(lines: Vec<Text>) -> Vec<Text>Expand description
The phones’ log lines (each with its device) as read_logs gives
them: oldest first, each text once by phone and row (a line named by
its id alone and the same row named with its date are one: a phone put
back on an older Sioul, which writes again under the old names what a
newer one read, never doubles a text on the computers; the review of 16
October 2026, MEDIUM 1), a deletion’s line folded into its text, a
line moved under its new name (its row’s date rewritten) shown under
that name alone, its old name kept beside it (also), so that a request
sent from a computer still finds its text (review of 18 October 2026, L-4).
