Artian's Casimir Boundary-Access Framework: Gauge-Invariant Plate Projectors, the Standard Coefficient, Three-2pi Non-Equivalence, and a Conditional Finite-Address Test

How two conducting plates reshape the photon spectrum without retuning the photon The ideal parallel-plate Casimir coefficient is familiar. The sharper question is what mathematical operation a conducting boundary performs on the physical photon space. This paper constructs that operation after Gauss reduction. If \(Γ_B\) is the perfect-conductor trace, the admissible one-photon space and its plate operator are \[ H_B=Γ_B∩ H_γᵖʰʸˢ, P_B^2=P_B=P_B^, M_B=Γ_s(P_B). \] The plate therefore changes the accessible photon domain while the source Maxwell law remains fixed. Explicit TE/TM counting gives two physical polarizations; the single TM \(n=0\) term is independent of plate separation after matched subtraction. The Abel--Plana cut then yields \[ { {ECas}{A} =- c/L^3 (π^2/6) [∫_0^∞{t^3\, dt}{e2π t-1}] (2ₚₒₗ) =-π^2 c/720L^3 } \] and \[ {{FCas}{A}=-π^2 c/240L^4}. \] The repeated number \(2π\) is then placed under an operator-level audit. Abel--Plana summation, Bisognano--Wichmann modular flow, and A7 completed-address capacity use the same scalar normalization in different typed objects: \[ 2πAP=2πBW=2πA7 ot⇒ OAP OBW OA7. \] A QTT bridge therefore requires an explicit reduced intertwiner: a quotient algebra, a unital star-homomorphism, state preservation, and modular-flow compatibility. Scalar coincidence alone is not that proof. The paper also derives a finite-address branch from the exact source stencil. For plates aligned with one native source rail, and only after declaring photon exposure and excluding an independent order-\(_A^2\) boundary-local coefficient, the branch gives \[ { {ECasᶜᵒⁿᵈ}{A} =-π^2 c/720L^3 [1+π^2/14(_A/L)^2 +O\!(_A^4/L^4)] } \] with the corresponding force law \[ { {FCasᶜᵒⁿᵈ}{A} =-π^2 c/240L^4 [1+5π^2/42(_A/L)^2 +O\!(_A^4/L^4)]. } \] The standard coefficient is recovered without a fitted parameter. The finite-address coefficients are closed within the printed constructor class; their laboratory use remains conditional on a photon-exposure and orientation map. Real-material tests must additionally pass through Lifshitz response, temperature, geometry, patch-potential, calibration, and covariance rows before a QTT verdict is allowed.
