| \chapter{Worked examples and the executed verification record} | |
| \section{A three-dimensional normal space} | |
| Take $d=3$ and $\lambda=1/2$, so $\coup=1/4$. The soul is the fixed | |
| three-dimensional Lie group $(\SO(3),Q)$ and the total manifold has | |
| dimension six. With individual preparation length $L=0.5$, the circle | |
| writer gives, to the displayed precision, | |
| \[ | |
| \beta=0.0049756\ldots,\qquad | |
| D_{\rm circle}=1.237808\times10^{-5}. | |
| \] | |
| The displayed angle is rounded; the files store substantially more digits. | |
| The exact formula, rather than this rounded value, is used in all | |
| calculations. The regular-simplex frame has | |
| \[ | |
| \lambda_{\min}(G)=3.713402\times10^{-5},\qquad | |
| \operatorname{cond}_2(G)=8.078645\times10^4. | |
| \] | |
| Its skew space has dimension three. Two sensor singular values are | |
| $3\cos\beta\sin\beta/\sqrt2$, while the third is | |
| $3\sin^2\beta/2$. Thus the weakest rotation is much less observable than | |
| the other two, even though the prepared vectors are linearly independent. | |
| In the Gaussian experiment with normalized $\sigma=10^{-4}$ and target | |
| risk $\alpha=0.05$, repeating this particular circle requires an | |
| illustrative integer threshold of $707$ shots. This is the exact formula | |
| for the selected loop evaluated numerically. It is not a certified statement | |
| that $707$ is the globally optimal finite-$L$ threshold over every possible | |
| loop. The geometric theorem proves equality of the leading asymptotic | |
| constant, not finite-length optimality of the circle. | |
| \section{Weak coupling at fixed soul and loop length} | |
| Table~\ref{tab:examples} holds the normal dimension at three and uses the | |
| same normalized detector noise and target risk. Only the connection parameter | |
| or the length of the chosen circle changes. Every positive-parameter row has | |
| full normal holonomy and the same soul metric. | |

| Gaussian formula, not interval-certified global finite-length optima.} | |
| \label{tab:examples} | |
| \end{table} | |
| The size of these numbers is a consequence of the declared scalar signal | |
| and independent noise model. It is not an estimate for a photonic device, | |
| a biological sensor, or an unspecified geometric computer. A detector with | |
| a different observable or radius-dependent variance would require a separate | |
| calibration before these numbers could be interpreted physically. | |
| The table nevertheless illustrates a rigorous qualitative separation. The | |
| holonomy group does not change as $\lambda$ decreases, whereas the weakest | |
| Gram direction and the scalar gap shrink. Increasing the number of exact | |
| algebraic directions does not force a favorable noise scale. | |
| \section{An explicit dimension-four frame} | |
| For $d=4$, choose $u=\mathbf1/2$ and let | |
| \[ | |
| Z=\sqrt{\frac43}(\Id-uu^{\mathsf T}). | |
| \] | |
| Its four columns are the unit vertices of a regular simplex in $u^\perp$. | |
| Set $V=\cos\beta\,u\mathbf1^{\mathsf T}+\sin\beta\,Z$. | |
| Then the Gram spectrum is | |
| \[ | |
| 4\cos^2\beta,\quad | |
| \tfrac43\sin^2\beta,\quad | |
| \tfrac43\sin^2\beta,\quad | |
| \tfrac43\sin^2\beta. | |
| \] | |
| The six-dimensional skew sensor has three singular values | |
| $4\cos\beta\sin\beta/\sqrt3$ and three singular values | |
| $4\sin^2\beta/3$. This is the smallest normal dimension in which the | |
| strong and weak skew layers have equal multiplicities. The formula is exact | |
| for all angles in the cap regime and supplies a direct, small matrix check | |
| of the resource law. | |
| \section{Exact-symbolic tests} | |
| The executable suite contains ten symbolic equality checks performed by | |
| SymPy. They verify the fixed-soul metric coefficient, the connection | |
| parameter, the curvature factor, the leading circle-angle coefficient, | |
| the inverse writer relation, fiber-curvature normalization, simplex spectral | |
| identities, and the mean and variance identities used by the Gaussian | |
| comparison kernel. These tests simplify expressions to zero or compare | |
| exact expressions. Their scope is the stated algebraic identities, not the | |
| entire differential-geometric proof. | |
| The finite algebra category contains seven checks. It includes generation | |
| of the skew Lie algebra and scalar-history reconstruction in selected | |
| dimensions. Some use floating matrix arithmetic and a stated numerical | |
| tolerance. The label ``algebra'' indicates what is being tested; it does | |
| not imply that every test in that category is exact arithmetic. | |
| \section{Numerical and high-precision tests} | |
| The numerical category contains $116$ tests. These cover the quotient | |
| minimization against the explicit metric, exact circle transport against an | |
| independently integrated ODE, arbitrary closed polygonal loop bounds, | |
| frame spectra, exterior sensor singular values, cap inequalities, inverse | |
| worst-direction attainment, Gaussian thresholds, noisy Gram calibration, | |
| and orthogonal completion of skew contractions. | |
| Six independent circle ODE integrations compare the exact transport with | |
| a high-accuracy adaptive integration. In the executed run the largest | |
| operator-norm discrepancy is below $1.3\times10^{-12}$. This is numerical | |
| agreement in those six instances; it is not an interval enclosure of all | |
| solutions or a proof of the exact writer theorem. | |
| Nine additional checks use 80-digit arithmetic for joint small-loop and | |
| weak-connection examples. They evaluate the normalized ratios | |
| \[ | |
| \frac{\beta}{\coup L^2/(4\pi)},\qquad | |
| \frac{D_{\rm circle}}{\coup^2L^4/(32\pi^2)},\qquad | |
| \left(\frac{\sin\beta}{\coup L^2/(4\pi)}\right)^2 | |
| \] | |
| for $\lambda\in\{0.5,0.01,10^{-8}\}$ and | |
| $L\in\{0.1,0.01,0.001\}$. These checks prevent ordinary floating-point | |
| cancellation from being mistaken for a vanishing geometric signal. | |

| \section{Reproducing the record} | |
| The recorded environment is Python 3.13.5, NumPy 2.3.5, SciPy 1.17.0, | |
| SymPy 1.14.0, and mpmath 1.3.0. The deterministic random seed is | |
| $20261020$. Run | |
| \begin{verbatim} | |
| python verify_aeqoria.py --output results/verification.json | |
| python create_examples.py | |
| \end{verbatim} | |
| from the release directory. The first command fails immediately when an | |
| assertion fails and writes the machine-readable record only after completing | |
| the checks. The second regenerates the illustrative circle tables with | |
| high-precision arithmetic. Run times depend on the environment and are not | |
| part of a mathematical performance claim. | |
| The JSON record includes each check's category, pass status, relevant | |
| residuals, and package versions. The accompanying CSV and JSON example files | |
| retain more numerical precision than the typeset table. No downloaded data, | |
| remote service, model checkpoint, or image generation is required to run | |
| the mathematical tests. | |
