Joel: does the 1.3% on delta_CKM close at NLO via A91/A92? Finding: the ANGLE is not the problem -- delta_CKM
= 31pi/84 = 66.43 deg is within PDG gamma = 65.9 +/- 3.3 deg (0.16 sigma), so the "1.3%" vs the central
65.6 is within experimental error, not a tension; and A92 shows the angle is at the sin-ceiling and cannot
move to fix the Jarlskog. The genuine NLO item is the Jarlskog invariant J_CKM (A91: A_NLO worsens it to
-8.2%). A92's paired-correction theorem restores it: (2,3)-block -> (1-4lam^2/5)^2 and (1,3)-block ->
(1+8lam^2/5) leave Q=A^2*Phi invariant to O(lam^2) (product = 1 - 0.48% = O(lam^4)). This is CONDITIONAL on
conj:g2-pairing (OP-P92-1): A^2*Phi/sin(delta_CKM) invariant under the Peirce-block Jordan loop as a G2-
structural identity. ADVANCE: the conjecture is motivated because the CP phase / unitarity-triangle area is
built from the G2-invariant associative 3-form phi (A66: dihedral = arcsin(s1 s2 phi(v1,v2,e7))), and
G2 = Stab(phi) preserves any phi-built quantity, so J is G2-invariant under off-diagonal rotation. The
remaining gap: that the specific paired NLO rescalings are forced by (not merely consistent with) the phi-
preserving structure; the (1,3) orbit dimension 5/8 is non-integer, confirming a structural G2 identity, not
a single Jordan loop. So: the angle is consistent (nothing to close), and the Jarlskog NLO closure is
reduced and advanced but not fully closed.).

CONTEXT. A395 found the quark off-diagonal CP phase delta_CKM = pi/3 + theta_C/2 = 66.43 deg is a 1.3% hit
(vs PDG 65.6). Joel: does it close at NLO via A91/A92? This probe runs that.

S0  the ANGLE is within experimental error -- delta_CKM = 66.43 deg vs PDG gamma = 65.9 +/- 3.3 -> 0.16
    sigma. There is no "1.3% tension" to close; the angle is consistent. A92 further shows it cannot move
    (sin(delta_CKM)=0.916 near the ceiling; 0.916*1.118 > 1).
S1  the genuine NLO item is the Jarlskog J_CKM = A^2 lam^6 eta: A91 propagated A_NLO=A_LO(1-4lam^2/5) and
    WORSENED J from -0.5% to -8.2%. Closing J needs eta_NLO ~ 0.3843 (+11.8%), from Phi not delta_CKM.
S2  A92 paired-correction theorem (algebraic): (2,3)->(1-4lam^2/5)^2 and (1,3)->(1+8lam^2/5) give
    Q=A^2*Phi invariant to O(lam^2): product = 1 + O(lam^4) (here -0.48%), restoring J_CKM at NLO.
S3  CONDITIONAL on conj:g2-pairing (OP-P92-1): the invariance is a G2 structural identity, not a single
    Jordan loop (the (1,3) orbit dimension 5/8 is non-integer).
S4  ADVANCE: J / the unitarity-triangle area is built from the G2-invariant associative 3-form phi (A66);
    G2 = Stab(phi) preserves phi-built quantities, so J is G2-invariant under off-diagonal rotation -- the
    structural reason conj:g2-pairing should hold.
S5  GAP (honest): that the specific paired rescalings are FORCED by the phi-structure (not merely
    algebraically cancel) is unproven; OP-P92-1 stays open, now sharpened to "show the paired NLO factors
    realize a phi-preserving G2 transformation."
S6  verdict: angle consistent (no tension); Jarlskog NLO reduced + advanced (restored to ~0.5% via the
    paired correction, motivated by phi's G2-invariance) but not fully closed.
