Same-Central-Effect Work-Quadrature Loop Preregistration: A Blind Circuit-QED Test of the QTT Access Intertwiner

Can one physical access gate control both extractable work and a closed phase-space commutator without retuning? This record seals a prospective circuit-QED test of the QTT Access Intertwiner. Its paper-native master equation is \[ \boxed{ \begin{aligned} w_j&:=\frac{\Delta\mathcal W_j}{\hbar\omega|\alpha|^2}=\eta_j,\\ \mathcal R_{jk}^{\rm QTT} &=(1-\eta_j)+\eta_j e^{J\phi_k},\\ \mathcal R_{jk}^{\rm QM}&=1,\\ \frac{\partial(\eta_j,\phi_k)} {\partial\mathcal R_{jk}^{\rm target}}&=0. \end{aligned}} \] A bosonic microwave mode is prepared in the symmetric ensemble \(|+\alpha\rangle\) or \(|-\alpha\rangle\). The preparation bit is written into an authenticated physical register. A randomized hardware route either makes that record available during the terminal window or keeps it unavailable until afterward. The work branch is a physical qualification. If the bit is available, a conditional displacement returns the mode to vacuum and the normalized gross energy drop is \(w_j=\eta_j\). Standard information thermodynamics and QTT both expect that row; it is not counted as QTT-exclusive evidence. The second branch is the discriminator. Four calibrated displacements form a closed phase-space group commutator. Ordinary canonical quantum mechanics predicts the same normalized geometric phase for every idle access setting. QTT predicts the exact complex surface \((1-\eta)+\eta e^{J\phi}\) from the same independently constructed central effect. Frozen design: five access settings: \(0,1/4,1/2,3/4,1\); four primary loop areas: \(\pi/4,\pi/2,3\pi/4,\pi\); positive and negative loop orientations; zero target-fitted QTT coefficients; one global complex-vector comparison under one frozen covariance; late-route, dummy-bit, matched-load, erasure, reversal, zero-area, state-transport, and complete-record controls. A theory verdict is legal only after an experiment-specific activation certificate freezes the physical effect, its complete terminal alphabet, the ordinary circuit model, all calibration quantities and covariances, crosstalk bounds, the work/loop route identity, and at least 90 percent power at a global one-sided five-sigma threshold before target data are opened.
