4220 — Reversible 1836 Haar Lift Preserves the Xi Energy Defect

Claim

Reconstructing the native 18361836-mode projectors gives ranks (12,3,1)(12,3,1) and support counts (108,432,1296)(108,432,1296). With w=Ne0w=Ne_0, ∥w∥2=1/180\|w\|^2=1/180, the normalized vector v=w/νv=w/\sqrt\nu defines Jh=v⊗hJ h=v\otimes h and R=J∗R=J^*. The exact identities are RJ=IRJ=I, JR=N⊗IJR=N\otimes I, and energy preservation. Amplifying the source diagonal prime operation by I⊗Tp(z)I\otimes T_p(z) preserves intertwining and recovery, but the scalar two-history defect remains exactly δ^p=δp\widehat\delta_p=\delta_p.

Attempting to unitarize TpT_p breaks faithful intertwining off the seam. A bounded intertwiner from full Haar translation to a fixed finite-dimensional unitary representation is zero because Haar translation has no L2L^2 eigenvectors. This is a whole-representation obstruction, not a no-go for reduced-fiber energy equality or moving/rigged realizations.

Scope

The construction is reversible but copies, rather than closes, the energy-defect equation. No off-seam Xi zero, Xi-specific one-step conservation, RH result, or global source realization is established. A finite-period Fourier substitute also loses a concrete norm-two orbit difference.
