Range measured: level 0, 16047040..16737344. 1875 whole 368-byte records
from the region start, variation checked across the first 60.
Method: the differential analysis that identified the shrub body -- compare
records byte by byte, record which positions differ.
Result: all 368 positions vary. No constant field, no padding, no header
inside a record. The shrub body separated immediately into a varying payload
and a constant two-byte tail; this format has nothing constant to separate.
That is consistent with the autocorrelation peak rather than in tension with
it. Checking which positions carry the 368-stride matches over 20000
positions gives 168 exact 4-byte repeats, distributed evenly at 0.84% across
all four byte offsets. Whole 4-byte sequences recur at exactly 368 while no
individual position is constant -- consistent with records containing entries
that repeat at a fixed relative index, not with a fixed-layout record.
So the 368 stride stands and the records stay unidentified. Worth recording
that the shrub method failed here for a specific and predictable reason: it
needs something constant to latch onto. Applying a method that worked
elsewhere is not the same as it applying here, and saying so is cheaper than
the next person assuming the technique transfers.
