Artian Monitored-Recurrence Reference-Switch Laboratory Protocol: A Preregistered, Activation-Gated A1 Test with First-Detection Resonances

A sealed phase-root test for two time-reference classes Version 2.03 of this preregistration asks one narrow experimental question: after the same monitored quantum system has passed through two physically qualified reference classes, does the location of a first-detection recurrence resonance remain invariant, or does it follow the single A1 projection? For each device (d) and preregistered resonance (j), the frozen observable is \[ y_{dj}=log\!\left(\frac{\widehat x^{*}_{dLj}}{\widehat x^{*}_{dAj}}\right), \qquad \widehat\Delta= \frac{\mathbf 1^{\mathsf T}\Sigma_y^{-1}\mathbf y} {\mathbf 1^{\mathsf T}\Sigma_y^{-1}\mathbf 1}, \qquad \widehat R_{\rm MRRS}=e^{\widehat\Delta}. \] The two sealed point branches are \[ H_0:\quad \Delta_0=0,\qquad R_0=1, \] \[ H_{A1}:\quad \Delta_{A1}=\log\!\cos\!\left(\frac{\pi}{8}\right) =-0.0791735919101875\ldots, \qquad R_{A1}=\cos\!\left(\frac{\pi}{8}\right)=0.9238795325112867\ldots . \] The (A1) point is not active merely because an oscillator is free-running. The candidate source terminal must first pass the completed-event physical terminal construction and its fifteen pre-data gates. Version 2.02 adds a second, independent standard-physics eligibility gate for phase-readout artifacts: \[ G_{\rm eligible}=G_{\rm PT}\,G_{\rm PI}. \] (G_{\rm PT}) is the original physical-terminal certificate. (G_{\rm PI}) requires a sealed path-and-component inventory, target-blind ordinary artifact injections, role-balanced mitigation or null controls, and explicit covariance propagation. For a heterodyne optical implementation, Type-I and Type-II parasitic paths are tested separately using ordinary phase-vector coupling models. The analysis keeps the measured conventional contribution where it belongs: \[ \phi^{\rm read}=\phi^{\rm phys}+\delta\phi^{\rm I}+\delta\phi^{\rm II}+\epsilon, \qquad \Sigma_y^{\rm total}=\Sigma_y^{\rm likelihood}+\Sigma_y^{\rm PI}. \] The source target is not altered by that procedure. A missing or failed artifact packet returns INELIGIBLE_NO_THEORY_VERDICT; it does not create a fitted correction or an alternative QTT branch. The protocol thereby separates three questions that should not be conflated: whether the physical terminal was constructed, whether ordinary readout artifacts are controlled, and which sealed point the qualified data support. The executable campaign fixes two devices, two independent oscillator chains, four reciprocal role cells, four roots, eight supercycles, a finite horizon (N=1024), an 81-point scan, and 2,048 trajectories per point per supercycle: \[ N_{\rm traj}^{\rm primary} =81\times2048\times8\times2\times2\times4 =84{,}934{,}656. \] The reconstructed likelihood retains the no-detection category and forbids manual fit windows, target-directed exclusions, a pseudoinverse, and post-unblinding regularization. The planning receipt reports (u_\Delta^{\rm synth}=0.0010808000) and a frozen point separation of (73.25) synthetic standard uncertainties. These are software and planning checks, not a hardware activation or laboratory result. Release status CLOSED: terminal-construction, blinding, root-fitting, covariance, and outcome-classifier instruction layers; CLOSED: ordinary parasitic-interference eligibility packet, target-blind synthetic pass/fail fixtures, and no-rescue firewall; PENDING: named-platform terminal construction and Type-I/Type-II (or justified non-optical equivalent) artifact packet; PENDING: qualified laboratory data and an empirical A1 verdict. The archive includes the paper PDF and LaTeX source, immutable base protocol, v2.01 and v2.02 amendments, the physical-terminal validator, a new parasitic-interference validator with synthetic pass/fail fixtures, raw-data schema amendment, reason-code registry, platform contract, finite-(N) power program, mechanical six-outcome classifier, render audit, and SHA-256 manifest.

A 22.5-degree or 45-degree component is no longer excluded by its angle alone: its physical transfer must be independently established. Common-operation cancellation and signal-preserving calibration are proved; both hypotheses must remain identifiable. Every acquired record is retained. After authorized unblinding, QTT-like, ordinary-like and unexpected outcomes are reported, including observations that do not qualify for a theory verdict. This is a prospective amendment, not a retrospective resealing of data. Clock, ruler and signal-recovery qualification. Both registered predictions are constructed at the raw detector with explicit proper-time, coordinate-time, worldline, ruler and synchronization conventions. Each relativistic effect is counted once. Independently calibrated corrections carry their uncertainties through the common comparison; the tested rows cannot train a normalization that forces either answer. Blind recovery is required separately for both alternatives at every predeclared operating setting. The inherited targets and decision rules remain fixed. The included design study makes sensitivity explicit: for the Two-Test Gram classifier, a total ratio uncertainty of 0.0013 gives approximately 88.9% QTT-branch and 94.1% ordinary-branch power under the stated ideal model. These are conditional detection probabilities, not probabilities that a theory is true, and each instrument retains its own classifier. The complete apparatus packet must be sealed before acquisition and target access; historical campaign rules remain preserved. Reconstruction entry point. Start with current/CURRENT_RELATIVISTIC_EXECUTION.md in the ZIP. The shared execution contract refers once to the development filename CURRENT_EXECUTION_RC.md; that reference means CURRENT_RELATIVISTIC_EXECUTION.md in this release. The packaged README names the correct file. This navigation correction does not change the deposited files, scientific requirements or historical seals.
