Identified the structure: a little-endian size field after the tag, then 0x01000000, a varying word, a zero, then a strictly ascending table. Sizes 64 / 108 / 348 bytes for three sample banks. Neither obvious reading gives the declared packet count. Entry count minus the three header words is exactly right for VOICE_D_452 (13) and wrong for the other two (24 vs 17, 84 vs 371) -- a one-of-three fit, recorded as FAILED rather than as a rule with exceptions, because two measurements today already returned plausible numbers for questions they could not answer. The ascending values step by 1.5-2.2 million, far too large to be packet indices, so they are on some other scale. Recorded what the next attempt should know, including that auto/slb-loader chains seek packet counts successfully by some field that is not either of the two tried here.
