"""v585 -- PRIME.LOCKSPLIT.01: the two-layer split of the locking cancellation: THE DOMINANCE IS DENSITY, THE LOCKING IS ARITHMETIC. Running the v583 prime-free model through the Paper-II normalised defect delta = det(B - S)/((B-S)_11 (B-S)_22) splits Problem 7.1's decay budget into two measured layers on the declared 69-window surface: density layer (deterministic): delta_PNT ~ h^{-1.43}, always positive, log-scatter 0.70 -- the prime-free model carries the one-mode GEOMETRY (lambda_2 near 1) and a coarse lock at the 1e-2..1e-4 level; arithmetic layer (the primes): an EXTRA cancellation factor ~ h^{-1.08} (median 1350x, growing 176 -> 7600) on top, bringing the real defect to h^{-2.51} -- and capable of overshooting through ZERO at the deep windows (real delta < 0 exactly at h = 1445, 1219; plus the 1292 anomaly), which the deterministic model never does. CONTRAST WITH v583: det S is reproduced by the density model to 1.02--1.14, the LOCKING defect is missed by 2--4 orders of magnitude: the same closed model separates what is density (the dominance, the pencil geometry) from what is genuinely arithmetic (the depth of the lock). BUDGET RELOCATION for Problem 7.1 (target h^{-3+eps}): the density layer supplies ~ -1.4 deterministically (classical analysis in principle), the arithmetic layer supplies the remaining ~ -1.1 (zero-oscillation territory). FIREWALL: same model as v583, no new inputs, no fit; slopes are surface-ladder measurements, no uniformity, no rate claim beyond the surface, NO RH statement; Problem 7.1 untouched. Verdict enums (frozen): TWO-LAYER-SPLIT (density layer misses the real lock by >= 2 orders while det S matches), DENSITY- LOCKED (density model reproduces the lock -- would kill the arithmetic layer), MIXED.
