Having found that the cue-less cutscene pages bind their audio through the movie
path, I tested the same explanation on the twelve script lines with no cue and
no bank. It fails: matching their caption text against every line in the
cutscene message table gives 0 of 14 hits, so nothing carries their audio by
another route.
They are ordinary story dialogue ('Katana, wait for me in hell'), which makes a
deliberate subtitle-only design unlikely -- but that is a judgement, not a
measurement, and why they are unvoiced is still open. Also noted: D_609 and
D_610 are equally unvoiced and simply are not among the twelve, because the
twelve counts script-called names and nothing calls them.
