Artian's Absolute-Clock Laboratory Discriminator Atlas

Where precision metrology still leaves room for a hidden clock Measurements of Newton's gravitational constant, rotating Mössbauer spectra, neutron lifetimes, spacecraft flybys, interferometric rotation, and precision clock comparisons do not all carry the same evidential weight. Some contain large residuals that remain inseparable from apparatus or channel models; others can support a sealed comparison between two fixed physical targets. This paper supplies a common statistical and experimental language for telling those cases apart. The central rule freezes the source before any laboratory camera is judged: \[ \boxed{ X_d^{\rm lab}(T)= \mathcal C_d\!\left[X^{\rm src};T,\tau,\mathbf e_d\right] +b_d+\epsilon_d, \qquad \frac{\partial X^{\rm src}} {\partial\{X_d^{\rm lab},\mathcal C_d,b_d,\epsilon_d\}}=0 } \] A high-significance residual is therefore an indicator, not automatically a clock observation. If a proposed clock waveform lies in the experiment's nuisance span, the clock is not identifiable. With covariance \(\Sigma\), nuisance matrix \(X\), and proposed clock vector \(q\), the decisive object is \[ \boxed{ q_\perp=(I-P_X)q, \qquad P_X=X(X^\top\Sigma^{-1}X)^{-1}X^\top\Sigma^{-1}, \qquad \|q_\perp\|_{\Sigma^{-1}}^2>0 } \] The strongest present laboratory indicator is precision \(G\). CODATA 2022 required a factor-3.9 uncertainty expansion across 16 inputs. A 2026 redetermination with the historic BIPM torsion balance reports \[ G_{\rm NIST,2026}=(6.67387\pm0.00038)\times10^{-11} \ {\rm m^3\,kg^{-1}\,s^{-2}}, \] which is \(4.05\sigma\) below the earlier result from the same apparatus but only \(1.05\sigma\) from CODATA. The same study carries material-persistent servo/free-deflection torque offsets at nominal \(6\sigma\) and \(7\sigma\). These facts justify a synchronized factorial replication; they do not yet identify an absolute clock because the unique QTT \(G\)-access waveform remains to be derived. The sharpest already sealed discriminator is the dual-channel Sagnac fork: \[ \boxed{ R_{\rm standard}=1, \qquad R_{\rm QTT}=\cos\!\left(\frac{\pi}{8}\right) =0.9238795325112867\ldots } \] The atlas ranks precision \(G\), dual-geometry Mössbauer rotation, same-flux neutron channel comparison, DSN flyby reprocessing, Faraday reference switching, and dual-channel Sagnac tests. Each programme includes a constructor ledger, nuisance-orthogonality gate, cross-camera transfer rule, sealed null, and kill condition. Atomic-clock and radioactive-decay nulls are retained as controls; the historic 5.9-year \(G\) periodicity is rejected as evidence. The PDF is the primary paper. The reconstruction ZIP contains the TeX source, verification script, numerical receipt, score rows, scientific audit, render audit, and SHA-256 manifest.
