This module (E3) fixes a single canonical normalization for the frozen GL (1) reduced determinant D₆₋ (₁) () (primitive spectral shift, with 0) and proves the determinant identity in the form D₆₋ (₁) (s) = (s) (with D₆₋ (₁) (s): =D₆₋ (₁) (s (1-s) ) ) by a rigidity argument. All determinant inputs (HT2/HT3, kernel-centering, cutoffs, and subtraction Pₑ₄₅^final) are imported from the frozen E2 determinant package closure. The log-derivative match on (s) >1 is imported from the Trace Prime modules. The basepoint/normalization is fixed only via ₒ + Q (s) =1 for the quotient Q (s): =D₆₋ (₁) (s) / (s), eliminating any ambiguity. Appendices record the formal complex-analytic lemmas, E2 integral convergence facts, Trace Prime glue identities, a formal wedge continuation/rigidity package, and (optionally) standard -function facts.
