The five-block result was measured on level 0 only. Rule 3a asks for the same
measurement per partition, so it was repeated on level 1's savestate before
being written up as a property.
Range measured: savestate slot 2 (level 1), RAM 0x22a000..0x28f52f, 415024
bytes, then six of its pointer-bearing records read to count*16.
The six sampled pointers split 3/3 between the two payload kinds:
00949430 41 00 00 00 30 sub-list
009496c0 13 69 b0 bf 80 fixed-point
00957970 36 00 00 00 30 sub-list
00957bb0 10 58 7e 8d 80 fixed-point
0095b740 12 37 49 41 80 fixed-point
0095d6d0 57 00 00 00 30 sub-list
Taking all six as sub-list gives 3/6 with five blocks. Taking only the three
that actually open 00 00 00 30 gives 3/3, with the first three blocks at 0, 32,
64 in all three. The three fixed-point payloads have zero such blocks, as
expected. The earlier 3/6 was my sampling, not a counterexample -- the six
pointers were never all the same kind of object.
Combined: 11 of 11 sub-list payloads across both levels have exactly five
blocks, the first three at offsets 0, 32, 64.
The fixed-point payloads have an exact signature: byte 3 of every 4-byte group
is 0x80 in 100% of cases -- 52/52, 40/40, 48/48 over the first 512 bytes of the
three level 1 samples, and the same across all nine level 0 payloads. That
separates the two payload kinds without the record tag, which does not select
them.
Correction: level 1's record tags are not level 0's. The same scan finds 18
04 04 00 01 headers against 19, plus 6 02 01 00 01 against 10, and byte 11 is
no longer constant: 0x30 on 10, 0x00 on 5, 0x20 on 2, 0xbc on 1, where level 0
had 0x30 on all 19. "Byte 11 is 0x30, constant" was a level-0 partition result
written up as universal; across both levels it takes four values.
Fixed-point payload entropy over all nine level 0 payloads is 5.51 to 5.89 bits
per byte against 8.0 for uniform, and the mean of the s16 reading varies per
payload from -82 to -907 -- structured, and consistent with vertex positions
relative to a per-payload origin.
Not established: what the five blocks are, and how the fixed-point data decodes
to vertices. Its entropy is far below random, so it is compressed or permuted
rather than stored plainly, and the permutation table seen once in 0x009376f0
remains unexplained.
