Summary. This paper develops a QMU-native method for quantifying polarized light in the Aether Physics Model (APM) by treating polarization as (i) a ledgered partition of conserved light-transport content and (ii) a mirror-odd chirality control that can couple to loxodromic geometry. The result is a falsifiable sign-ledger that enables polarization-programmable nonreciprocity and a practical pathway toward bias-free optical isolation. What is new. The work contributes three concrete deliverables: A Stokes-like polarization vector S= (S₀, S₁, S₂, S₃) with S₀=ligt (transport content in QMU) and S₁, ₂, ₃ defined as signed ligt-partitions between analyzer channels. This makes polarization a ledger-native variable that can be swept while holding transport invariant. A dimensional polarization chirality carrierC₎₋ = sₕ\, (Aᵤ curl) = sₕ\, Fq²C²anchored to Ledger One and mirror-odd like the loxodromic carrierC₋₎ₗ= (₆₄₎C) (Aᵤ curl) A sign-ledger extension predicting polarization-programmable nonreciprocity: sgn (gf) =pₖ\, s₋₎ₗ\, mₑ₄₌\, sₕwhere pₖ is propagation-direction sign, s₋₎ₗ is geometry handedness sign, mₑ₄₌ is branch (history) sign, and sₕ is helicity sign. Engineering outcome. The paper frames a bias-free optical isolator (polarization diode) as a pseudoscalar logic element whose operating truth table is enforced by discrete sign flips rather than by continuous external bias fields. A near-term architecture is a loxodromic guide plus a reprogrammable chiral boundary (e. g. , a tunable circular-dichroism metasurface), with verification by helicity-reversal sign tests and QMU-normalized downscaling fits. Experimental protocol (falsifiable). A Helicity-Reversal Sign Ledger (HRSL) protocol is included: (i) lock transport by enforcing S₀ (RCP) =S₀ (LCP) =ligtₒ₄ₓ, (ii) sweep the discrete controls \pₖ, s₋₎ₗ, mₑ₄₌, sₕ\, (iii) require sign inversion under any single flip and parity restoration under paired flips, (iv) test magnitude collapse to the QMU scaling template| gf|=A (k, ) / r + B (k, ) / r² How to cite.
