Nonce-prefix regional persistence
Pilot B8 density within a high-byte nonce region predicts density in a disjoint low-24-bit holdout from the same region.
Diagnostic work, exact algebra and local capabilities are not treated as end-to-end mining advantage.
What was tested?
Pilot B8 density within a high-byte nonce region predicts density in a disjoint low-24-bit holdout from the same region.
Why the test is meaningful
Regional persistence requires out-of-sample correlation across many nonce prefixes, not an isolated positive header.

Test four independent headers, 2^10 pilot and 2^13 holdout nonces per region, plus 64 equal-work random selections.
What happened
One panel reached 1.0731× B8, while the others were 1.0032×, 0.9272× and 0.9833×. Aggregate B8 lift was 0.9963 and net gain 0.9982; correlation was −0.00738 with permutation p=0.59395.
Exactness and statistical controls
A malformed first manifest was archived before data; only the missing checksum block was repaired and the complete campaign repeated with 9,437,184 hashes and zero audit discrepancies.
What the result means
No transferable persistence exists for the registered high-byte regions; the isolated positive panel is treated as noise.
Limitations
- The region definition is fixed to the nonce high byte.
- Other partitions require fresh hypotheses.
- No operational selection is authorized.
Evidence trail
Use frozen regions, disjoint windows, equal-work controls and report every header, including reversals.
