EXACT MATHEMATICAL REPLAY
Four holds.
Five breaks.
The exact Pólya-frequency order of the Riemann kernel is four: every translation minor through order four is strictly positive, while one exact order-five minor is negative.
The boundary is the result.

ORDER 2positivestrictly positive globally

ORDER 4positivestrictly positive globally
ORDER 5negativeone exact witness stops the extension
Why it is different
The investigation stopped being a regional atlas and became a replayable boundary. The paper, exact arithmetic, frozen witness, and proof assistant all state the same result: four survives globally; five fails exactly.
