Dereferenced all nine pointers in the level 0 table that carry the 0x30 tag at byte 11 and an EE pointer at 12..15, reading 32 bytes each. They fall into exactly three classes, three payloads each, with no overlap. A, Q16.15 fixed-point vertex data (3 of 9): every high byte 0x80 or 0x7c, repeating on an 8-byte boundary, values differing per payload while the 4e 4e 4c 80 tail is shared by two. 00936a70 8d 8c 80 80 89 87 7c 80 ... 4e 4e 4c 80 0093cde0 8a 8a 7f 80 92 90 84 80 ... 4e 4e 4c 80 009cf4f0 6e 6f 68 80 6e 6f 68 80 ... 54 54 51 80 B, a 0x30 sub-list with a repeated word (3 of 9), structurally identical apart from that word (0xcd, 0xc0, 0xc8), all carrying 01 00 00 05 at offset 16 and a ".. c1 01 6e" at 20. 009376f0 00 00 00 30 cd 00 00 00 cd 00 00 00 ... 00998880 00 00 00 30 c0 00 00 00 c0 00 00 00 ... 009d2da0 00 00 00 30 c8 00 00 00 c8 00 00 00 ... C, an index/attribute list (3 of 9), both opening 00 c0 05 6d, then a count, then a run of small ascending u16. 00939700 00 c0 05 6d 3e 00 00 00 01 00 00 00 ... 009c1540 00 c0 05 6d 36 00 00 00 01 00 00 00 ... So the tag vocabulary measured on disc at record byte 7 -- 0x00, 0x30, 0x6d, 0x80 -- selects the payload: 0x30 class B, the 00 00 00 30 sub-list 0x6d class C, the 00 c0 05 6d attribute list 0x00 class A, the fixed-point vertex data 0x30 heads the class B payloads and 0x6d heads the class C payloads. That was flagged as a single coincidence two commits back; three payloads each makes it a rule. 0x80 has no sample among these nine and its meaning stays open. Correction: the record spacing in this table is not uniformly 0x30. The find output shows 0x30, 0x10, 0x30 between consecutive packet headers, and only 9 of the 5632 bytes scanned carry both the 0x30 tag and an EE pointer. The earlier "0x30 spacing" was inferred from a truncated hit list.
