SEAM.EQUIV.B01 — Route B (DtN): the full-L² lift of the sub-principal Z4 block-diagonality, proving (numerically, on the full Toeplitz operator) the 'probably provable' step and lifting v201/v284 from the finite block to L². [E] character orthogonality: a mark-sourced curvature f=Σ_{j<4} g(θ−jπ/2) has Fourier support only on m≡0 mod 4 (nonzero modes {0,±4,±8,±12}; the 4th-root mark sum Σ_{j<4}((−i)^m)^j=4[4|m]); [E] full-L² block-diagonality: Λ=|n|+M_f commutes with ρ=diag(i^n), ‖[ρ,Λ]‖~2e-15 on −50..50; [E] negative control: a generic curvature gives ‖[ρ,Λ]‖=4.44>0; [E] Lean consistency (geom_sum_fourth_root + markLocal_blockDiagonal); [O] the sharper residual — why is the raw seam sub-principal term mark-local? (the curvature-locality half of SEAM.EQUIV.01).
