"""v595 -- PRIME.MAPCLOSE.01: the residual bookkeeping, executed: the v593
residual was the SIGMA MAPPING, and with the exact dictionary the
closed forms match the deterministic model at the identity level.

THE DICTIONARY [E]: the lag variable is sigma = d/N, so the continuum
form of the cell sum is NOT the alpha-Laplace integral but

    S_ij = 2 a_eff  Integral_{u0/(ND)}^{2 alpha/(ND)}
           e^{a_eff sigma} g_ij(sigma) dsigma,   a_eff = N D / 2

(N D = 2 alpha + O(D) by the window construction, which is exactly why
the alpha-form of v593 carried a first-order-in-D residual).  The
antiderivatives are the same elementary functions, evaluated at both
ends.  RESULTS: entries AND determinant match the v583 grid model to
1.00000--1.00017 across the ladder (worst 1.7e-4 at the smallest
window, 1.00000 at h = 1445) -- the deterministic layer of Problem
7.1 is now closed at the numerical-identity level.  THE DECOMPOSITION
[E]: the kernel correction (exact W vs macro g at sigma = d/N) enters
at 4e-6 -- 4e-5 (the genuine O(1/N^2) piece), the mapping carried the
entire v593 residual (0.72% -> 0.19%), and the discretization is below
both.  HONEST AMENDMENT: v593's reading of its residual as
'O(1/N^2) kernel corrections' was wrong in attribution -- the residual
was first-order in D through the mapping; this module supersedes that
interpretation (the v593 numbers stand).

FIREWALL: closed forms exact; comparisons at declared windows; the
remaining gap to the REAL data is the arithmetic layer (v585/v589/
v594), untouched here; no uniformity, no rate, NO RH statement.
Verdict enums (frozen): MAPPING-CLOSES (det within 2e-4 on the
ladder), PARTIAL, FAILS.

PROVENANCE: discovery probe mapping_completion_probe.py (2026-08-01,
4/4, MAPPING-CLOSES); v583/v593 read-only.
Python-only, counted per GATE.WOLFRAM.02.
