I did some further investigation. break-visibility would work on StanzaNumber if it were associated with a NonMusicalPaperColumn. "Non-musical" grobs such as Clef and KeySignature are copied twice and exist in three forms per measure at one point: one for beginning-of-line, one for mid-line, one-for end-of-line, to be used or discarded when line breaks are decided -- lots of grobs are suicided. The unneeded grobs are thrown out based on the break-direction. If you apply ly:item-break-dir to StanzaNumber you will always get 0 = unbroken, so break-visibility is useless. The extra copies aren't made for "musical" items, anyway. The trick I used was to locate a neighboring NonMusicalPaprtColumn, which would have break-directions of -1, 0, or 1. You could extend the procedure for determining line beginnings by looking at 'right-column for line ends.
