T36: review round 1: every pair of a known key is checked before the last of each key wins, a clear's too, so a report that breaks a rule anywhere drops whole; a sequence counts its length from OSC through ST with the controls its body skips; the scanners pass DEL and high bytes by in an escape as vte does, so ESC DEL c resets the records too
