16 of the 17 pages with an empty slot 4 belong to MSG_DEMO_600..604, whose caption text matches, word for word, the five resupply lines documented from the movie side as VOICE_D_450..454. Slot 4 is empty on purpose: that audio binds through the movie path, not through a DEMO_nnn cue. That also disposes of the '5 ids with more than one record' item -- each appears once per stage that uses it, and the repeat counts equal the movie-slot counts recorded independently for the matching banks: 3/3/4/4/2 both ways, 5 of 5. The 11 extra records over 138 ids are these repeats. Worth more than closing two items: the cutscene message table and the movie subtitle chain were decoded from different containers by different routes and agree on the same five lines with the same multiplicities. MSG_DEMO_500 remains: one page, KATANA, 2s, no text and no cue.
