QGEO.VARI.01
QGEO.VARI.01
THE E_fail VARIATIONAL FUNCTIONAL (external-review path 1, 2026-06-14): a concrete, numerically-testable sharpening of the v194/QGEO.ENERGY.02 target. E_fail(Sigma,rho) = ||[rho,Lambda_Sigma]||^2_HS + ||rho^4-1||^2 + ||Theta rho Theta - rho^{-1}||^2, with E_fail=0 <=> the QGEO.SYM.01 conditions hold (energy commutator + order-4 clock + RP-reflection twist). (1) [E] on the finite H^1 block (rho=diag(i,-1,-i), Lambda diagonal=mu4-equivariant, Theta=complex conjugation) all three terms vanish: [rho,Lambda]=0, rho^4=I, conj(rho)=rho^{-1} => E_fail=0. (2) [N] a mu4-breaking off-diagonal Lambda gives [rho,Lambda]!=0 and a non-order-4 rho gives rho^4!=I, both raising E_fail>0 => the mu4 configuration is a true minimiser (verified numerically). (3) [I] the zero locus is exactly the seam-deck conditions of QGEO.SYM.01. (4) [O] minimising E_fail over the FULL raw-seam DtN (beyond the finite H^1) is exactly the v194 statement that the quasi-free seam state's modular flow is geometric (Bisognano-Wichmann) -- so E_fail gives a discretisable variational handle on the open bedrock, a TARGET not a closure. Python-only (finite-block linear algebra; finite vanishing exact, Wolfram-mirrored)
Recorded status: Numerical/identity [N]/[I] (finite vanishing exact) + target [O] (full-operator min = BW)
Dependencies, status detail and source
Canonical status: Numerical/identity [N]/[I]: E_fail=0 exactly at the mu4 config and >0 for perturbations (mu4 minimiser); full-operator minimisation = the v194 Bisognano-Wichmann residual [O] -- a concrete discretisable handle on the bedrock
