\title{Shapiro Time Delay\\\large Three-Axis FrostClock Coupling, Reproduction Mathematics, and Post-Seal GR Ruler}
\author{Frostyverse Laboratory}
\date{Website Laboratory v1.0.48}
\maketitle

\statusbox{\textbf{Scientific status.} This Laboratory reproduces the provisionally frozen H-116 gravitational photon-timing candidate, with H-118 high-resolution confirmation. The Frostyverse field, local three-axis clock coupling, photon path, and differential timing are generated first and SHA-256 sealed while General Relativity (GR) is closed. The external weak-field Shapiro ruler is opened only afterward. No GR/FV amplitude correction is inserted into the FV timing law. A software PASS is an internal computational result, not experimental proof that nature contains FrostCells.}

\begin{abstract}
This note exposes the calculation performed by the public Shapiro Time Delay Python Test so a physicist need not reverse-engineer the historical source. H-115 had found that the frozen Frostyverse gravity/photon machinery reproduced the shape of differential Shapiro timing but its raw timing amplitude approached roughly $1.5$ times the external ruler. H-116 did not divide by that discrepancy. Instead it proposed a parameter-free local three-axis clock coupling measured from the actual deformed FrostCell geometry, generated fresh FV timing predictions, sealed them, and only then opened the GR comparison. The public wrapper calls the unchanged H-116 machinery for both its focused reference and custom normalized geometries; H-118 preserves the same clock mechanics at higher resolution.
\end{abstract}

\section{Question under attack}
Photon fly-by and Shapiro delay are related but distinct observables. Photon fly-by asks whether the frozen deformation field changes a photon's \emph{direction}. Shapiro delay asks whether, along that already-frozen FV path, the same deformation/clock machinery also generates the additional \emph{travel time} associated with the field.

The timing audit therefore does not retune photon steering, node completion, or the field source. The inherited frozen steering magnitude is
\[
\lVert\mathbf r_{\rm steer}\rVert
=K R^2\sqrt{C_{\rm cell}}\,\sin^3\theta,
\qquad
K=8.6816265415871847\times10^{-5},
\qquad p=0,
\]
with the H-089 \code{WALL\_CONTINUOUS} trajectory lane retained unchanged.

The narrow question is:
\begin{quote}
Does a clock coupling constructed only from local three-axis FrostCell deformation turn the already-frozen FV path into a differential Shapiro timing prediction that survives fresh geometry and resolution checks without using the GR answer during generation?
\end{quote}

\section{Normalized public geometry}
The H-116 harness uses normalized FrostField coordinates. The public focused test exposes
\begin{center}
\begin{tabular}{ll}
\toprule
Input & Meaning \\
\midrule
$R$ & numerical FrostField resolution \\
$H$ & endpoint half-length; the nominal straight path spans $x=-H$ to $x=+H$ \\
$b$ & target ray impact parameter \\
$b_{\rm ref}$ & farther comparison ray used to form a differential delay \\
workers & numerical worker count passed to the historical solver \\
\bottomrule
\end{tabular}
\end{center}

The finite timing shell is frozen at
\[
\boxed{r_0=9.90}.
\]
Focused inputs must satisfy
\[
R\in[12,80],\qquad H>0,\qquad b>0,\qquad b_{\rm ref}>0,\qquad b\neq b_{\rm ref},
\]
and both endpoint radii must remain inside the timing shell,
\[
\sqrt{H^2+b^2}<r_0,
\qquad
\sqrt{H^2+b_{\rm ref}^2}<r_0.
\]

\statusbox{\textbf{Source-mapping boundary.} The wrapper deliberately does not expose an arbitrary physical mass knob. H-116 used a frozen normalized FV source and a synthetic weak-field comparison ruler with $M=10^{-6}$. A general physical mass-to-FrostField-source mapping was not established by this test, so the website wrapper does not invent one.}

\section{Frostyverse three-axis clock calculation}
\subsection{Affine deformation of one FrostCell}
For each sampled FrostCell, the unchanged H-116 code obtains the eight deformed FrostNode corner positions and fits their local affine frame. Let the resulting deformation matrix be $F$. Because the nominal cell edge is $1/R$, the historical code scales the fitted basis by $R$ before examining deformation.

Let the singular values of $F$ be the three principal stretches
\[
\sigma_1,\sigma_2,\sigma_3>0.
\]
The signed principal log strains are
\[
\boxed{\epsilon_i=\ln\sigma_i}.
\]
Define
\[
e_i=|\epsilon_i|,
\qquad
e_{\max}=\max_i e_i.
\]
H-116's completed-state three-axis clock coupling is
\[
\boxed{
C_{3D}
=\frac{\frac13(e_1+e_2+e_3)}{e_{\max}}
=\frac{\operatorname{mean}_i|\epsilon_i|}{\max_i|\epsilon_i|}
}.
\]
For a numerically undeformed cell with vanishing dominant strain, the implementation uses the neutral upper-bound value $C_{3D}=1$ rather than divide floating-point noise.

No numerical factor $2/3$, no GR timing result, and no fitted amplitude coefficient appears in this definition. Because it depends on singular values, the scalar is rotation invariant under a rigid change of coordinate frame. H-116 separately checks its X/Y/Z covariance numerically.

\subsection{Raw and clock-weighted radial envelopes}
At radial grid samples
\[
r_n=\frac{n}{R},
\qquad
r_n\in[1.10,9.90],
\]
the inherited local field machinery returns the current-cell convergence magnitude $C_{\rm cell}(r_n)$. The old H-115 raw timing envelope is
\[
\boxed{
A_{\rm raw}(r)
=K R^2\sqrt{C_{\rm cell}(r)}
}.
\]
The H-116 candidate replaces no field or steering physics; it weights that envelope by the local geometric clock coupling,
\[
\boxed{
A_{\rm clock}(r)
=C_{3D}(r)\,A_{\rm raw}(r)
=C_{3D}(r)K R^2\sqrt{C_{\rm cell}(r)}
}.
\]
The unweighted $C_{3D}=1$ envelope is retained as a negative/control lane.

\subsection{Finite-shell potential construction}
With the outer shell set to zero, H-116 integrates inward,
\[
\boxed{
\Phi_{\rm clock}(r)
=\int_r^{r_0}A_{\rm clock}(s)\,ds,
\qquad
\Phi_{\rm clock}(r_0)=0
}.
\]
The program evaluates this on the radial table using the trapezoidal rule. In discrete form, stepping inward through adjacent radial samples,
\[
\Phi_j
=\Phi_{j+1}
+\frac12\bigl(A_j+A_{j+1}\bigr)(r_{j+1}-r_j).
\]
The raw-control potential $\Phi_{\rm raw}$ is generated by the identical integration with $A_{\rm raw}$.

\section{Timing the frozen FV photon path}
For a ray launched from approximately $(-H,b,0)$, the unchanged H-089 wall-continuous transport returns successive event positions $\mathbf x_j$ and cell-exposure lengths $\Delta s_j$. Let
\[
L_{\rm FV}=\sum_j\Delta s_j
\]
be the traveled path length and
\[
\Delta L_{\rm path}=L_{\rm FV}-2H
\]
be its excess over the nominal straight endpoint separation.

For each exposure, the timing field is sampled at the segment midpoint,
\[
\mathbf x_{j+1/2}=\frac12(\mathbf x_j+\mathbf x_{j+1}),
\qquad
r_{j+1/2}=\lVert\mathbf x_{j+1/2}\rVert.
\]
The clock-potential exposure is
\[
I_{\rm clock}
=\sum_j\Delta s_j\,\Phi_{\rm clock}(r_{j+1/2}),
\]
so the candidate FV delay for one ray is
\[
\boxed{
\Delta t_{\rm FV}(b,H)
=\Delta L_{\rm path}+I_{\rm clock}
}.
\]
The raw negative-control delay is computed identically with $\Phi_{\rm raw}$.

H-116 scores a \emph{differential} Shapiro observable against a farther ray:
\[
\boxed{
\Delta t^{\rm diff}_{\rm FV}
=\Delta t_{\rm FV}(b,H)
-\Delta t_{\rm FV}(b_{\rm ref},H)
}.
\]
This subtraction is performed while the external GR ruler remains closed.

\section{FV-first firewall and candidate seal}
The focused wrapper executes the following order:
\begin{enumerate}
\item solve the unchanged H-116 symmetry-clean $p=0$ FrostField;
\item measure the radial $C_{3D}$ table and clock potential;
\item propagate the target and reference FV photon paths;
\item compute FV target, reference, differential, raw-control, and covariance quantities;
\item serialize the FV-only scientific payload and SHA-256 seal it;
\item release the large field object; and
\item only then call the historical GR timing function.
\end{enumerate}

Runtime is excluded from the scientific seal because it is machine dependent. The wrapper prints
\begin{verbatim}
GR consulted before seal: NO
\end{verbatim}
so the sequencing is visible during reproduction.

\section{External weak-field Shapiro ruler}
Only after the FV result has been sealed does the historical H-116 code open its synthetic weak-field ruler. In the historical normalized units,
\[
M=10^{-6},
\qquad
r=\sqrt{H^2+b^2},
\qquad
D=2H.
\]
For one ray the comparator is
\[
\boxed{
\Delta t_{\rm GR}(b,H)
=2M\ln\!\left(\frac{2r+D}{2r-D}\right)
}.
\]
The comparison observable uses the same target-minus-reference construction,
\[
\boxed{
\Delta t^{\rm diff}_{\rm GR}
=\Delta t_{\rm GR}(b,H)
-\Delta t_{\rm GR}(b_{\rm ref},H)
}.
\]
The reported amplitude ratio and relative error are then
\[
\mathcal R=\frac{\Delta t^{\rm diff}_{\rm FV}}{\Delta t^{\rm diff}_{\rm GR}},
\qquad
\varepsilon_{\rm rel}=|\mathcal R-1|.
\]

\statusbox{\textbf{Comparison firewall.} The GR expression above is an external ruler. Its value is not supplied to the FV field, $C_{3D}$ construction, photon steering, radial potential, or timing integration. The frozen comparison compactness $M=10^{-6}$ also is not exposed as an FV source-normalization parameter.}

\section{Public focused reference}
The lightweight public reference reproduces a preserved H-116 geometry:
\[
R=20,\qquad H=7.0,\qquad b=3.30,\qquad b_{\rm ref}=6.80.
\]
A fresh run of the public package gives:
\begin{center}
\begin{tabular}{lr}
\toprule
Quantity & Reference result \\
\midrule
FV target clock delay & $3.135655361639234\times10^{-6}$ \\
FV reference clock delay & $7.759446571338321\times10^{-7}$ \\
FV differential clock delay & $2.359710704505402\times10^{-6}$ \\
Old raw-envelope differential & $3.533439041454356\times10^{-6}$ \\
Radial $C_{3D}$ median & $0.667921260020$ \\
X/Y/Z $C_{3D}$ relative spread & $2.662\times10^{-7}$ \\
Post-seal GR differential & $2.378186376373909\times10^{-6}$ \\
FV / GR & $0.992231192621$ \\
Relative error & $0.776881\%$ \\
Old raw envelope / GR & $1.485770449515$ \\
\bottomrule
\end{tabular}
\end{center}

The raw control is important: the old unweighted timing envelope remains about $1.49\times$ the external ruler. The H-116 candidate does not hide that failed lane or divide it by a fitted correction.

\section{Fresh/custom-input attack}
A reviewer can change the normalized geometry while keeping the same FV mechanics. For example,
\begin{verbatim}
python lab_test.py --custom --R 20 --half 5.5 \
    --b 2.75 --b-reference 6.40
\end{verbatim}
A fresh run of that example produced
\begin{center}
\begin{tabular}{lr}
\toprule
Quantity & Fresh result \\
\midrule
FV differential clock delay & $2.637208123855666\times10^{-6}$ \\
Post-seal GR differential & $2.661085471898858\times10^{-6}$ \\
FV / GR & $0.991027214911$ \\
Relative error & $0.897279\%$ \\
Old raw envelope / GR & $1.483566720631$ \\
X/Y/Z $C_{3D}$ relative spread & $1.480\times10^{-7}$ \\
\bottomrule
\end{tabular}
\end{center}
A failure on a fresh legal geometry is a useful audit result and should be reported, not tuned away.

\section{Historical holdouts and resolution behavior}
H-116 predeclared its interpretation gates before opening the external ruler:
\begin{align*}
\text{fresh direct relative error} &\le 2.0\%,\\
\text{within-geometry ratio spread} &\le 1.5\%,\\
\text{cross-resolution amplitude drift} &\le 2.5\%,\\
\text{axis-coupling covariance spread} &\le 0.5\%.
\end{align*}
These are diagnostics, not coefficients in the FV equations.

The preserved H-116 full audit reported approximately:
\begin{center}
\begin{tabular}{lrr}
\toprule
Resolution & $C_{3D}$ radial median & Preserved fresh-error summary \\
\midrule
R20 & $0.667921260$ & up to $1.1282\%$ \\
R40 & $0.667302801$ & up to $0.5758\%$ \\
R80 & $0.667114603$ & $0.2979\%$ ($H=4.5$) / $0.2816\%$ ($H=7.0$) \\
\bottomrule
\end{tabular}
\end{center}
For the focused $H=7.0$, $b=3.30$ row, the preserved FV/GR errors are about $0.7769\%$ at R20, $0.4000\%$ at R40, and $0.2103\%$ at R80.

H-118 retained the same clock mechanics and reported worst Shapiro residuals of approximately
\[
0.2816\%\ (R80),\qquad
0.1872\%\ (R120),\qquad
0.1217\%\ (R160).
\]
The decreasing residual is evidence about numerical convergence of this candidate; it is not an experimental measurement.

\section{Negative controls and useful reviewer attacks}
A serious reproduction should preserve or extend these attacks:
\begin{itemize}
\item keep the old $C_{3D}=1$ raw timing lane visible instead of renormalizing it after seeing GR;
\item repeat X/Y/Z sampling of the geometrically derived $C_{3D}$ and look for orientation dependence;
\item use fresh legal $H$, $b$, and $b_{\rm ref}$ values rather than replaying only the development set;
\item confirm that FV timing and its fingerprint exist before the GR function is called;
\item leave the frozen H-089 photon path mechanics unchanged while testing timing;
\item test resolution dependence rather than treating one grid as the continuum answer;
\item attack the finite-shell dependence instead of silently moving $r_0$ to improve the comparison; and
\item report fresh-input failures rather than introducing a source or amplitude fit.
\end{itemize}

\section{How to reproduce the public Python Test}
Requirements are Python 3.10+, NumPy $\ge1.24$, and SciPy $\ge1.10$. From the extracted Python Test directory:
\begin{verbatim}
python -m pip install -r requirements.txt
python lab_test.py
\end{verbatim}
The interactive menu offers the focused reference, custom geometry, historical validation/full profiles, and archive verification.

Direct commands include:
\begin{verbatim}
python lab_test.py --reference
python lab_test.py --custom --R 20 --half 5.5 \
    --b 2.75 --b-reference 6.40
python lab_test.py --historical h116-validation
python lab_test.py --historical h116-full
python lab_test.py --historical h118-validation
python lab_test.py --historical h118-full
python lab_test.py --verify
\end{verbatim}
Focused reference/custom runs save timestamped TXT and JSON reports under \code{results/}. Historical runs execute the unchanged archived scripts in a temporary directory unless \code{--keep-historical-output} is supplied.

\subsection{Resource warning}
The original high-resolution calculations are genuinely large. Preserved main-field-array sizes are approximately
\[
3.810\ \mathrm{GiB}\ (R80),\qquad
12.864\ \mathrm{GiB}\ (R120),\qquad
30.499\ \mathrm{GiB}\ (R160),
\]
before normal Python/process overhead. The public menu asks for explicit confirmation before launching the heavy profiles.

\section{Browser Laboratory scope}
The browser visualization is a sealed-case explorer, not the multi-GiB field/timing solver. The downloadable Python Test is the reproducibility target for the numerical calculation described here.

\section{Claim boundary}
The supported statement is limited: the declared H-116 three-axis FrostCell clock-coupling software candidate survived its specified fresh normalized Shapiro holdouts, its old raw-envelope control remained visibly wrong in amplitude, and the frozen candidate continued to show decreasing residuals in H-118's higher-resolution numerical runs. This does not establish that nature uses FrostCells, does not derive a general physical mass-to-source map, and does not justify inserting GR timing information into the FV calculation.
