The dead-letter row and a max-deliveries advisory without a token both said bus.<stream>.<consumer>.max-deliveries: each look added an observation and a line of evidence through the row, and the two overwrote each other's words. The row owns the key since issue 330, so the advisory watcher leaves it, and the row now says when the newest held message was given up, so a letter held for a day no longer reads as observed every 30 seconds. Times without Happened is refused, since the raise ignored it and an update counted it.
