The Time Arrow in a Residual Clock Sector: Mathematical Closure, Numerical Diagnostics, and CMB Transfer Curves

This record contains Version v1.0 of a four-paper package on the time arrow in a residual clock sector. The package develops a scope-defined theorem-and-diagnostic framework for operational-time entropy production, residual phase relaxation, mathematical gradient-flow closure, numerical diagnostics, and CMB transfer-level signatures.

The central structural spine is

$$
\alpha=d\Phi-A
\Longrightarrow
L_\alpha
\Longrightarrow
T
\Longrightarrow
K_T
\Longrightarrow
\text{residual entropy production}.
$$

Here \(\alpha=d\Phi-A\) is residual phase tension, \(L_\alpha\) is a structural lapse, \(T\) is operational time, and \(K_T\) is the generator measured in that clock. The parent paper formulates a residual clock-sector second-law identity in an \(L^2(h_T)\) gradient-flow setting. If

$$
D_T\alpha
=
-\operatorname{grad}_{L^2}\mathcal A_{\mathrm{res}}[\alpha],
$$

then the residual action is a Lyapunov functional:

$$
\frac{d}{dT}\mathcal A_{\mathrm{res}}[\alpha(T)]
=
-\|\operatorname{grad}_{L^2}\mathcal A_{\mathrm{res}}[\alpha(T)]\|^2_{L^2(h_T)}
\le 0.
$$

The associated residual entropy-production ledger satisfies

$$
\frac{dS_{\mathrm{res}}}{dT}
=
\gamma
\|\operatorname{grad}_{L^2}\mathcal A_{\mathrm{res}}[\alpha(T)]\|^2_{L^2(h_T)}
\ge 0.
$$

Version v1.0 adds a mathematical closure layer. The closure note replaces a purely formal gradient-flow identity by a closed Hodge-coercive residual sector. In the canonical compact boundaryless setting, the residual action is

$$
\mathcal A_{\mathrm{res}}[\alpha]
=
\frac12
\int_\Sigma
\left(
c_0|\alpha|^2
+
c_d|d\alpha|^2
+
c_\delta|\delta\alpha|^2
\right)
d\mu_h.
$$

The associated operator is

$$
\mathcal L
=
c_0 I
+
c_d\delta d
+
c_\delta d\delta.
$$

The closure note proves that this positive self-adjoint generator produces a global residual gradient flow,

$$
\alpha(T)=e^{-T\mathcal L}\alpha_0,
$$

with the energy-dissipation identity

$$
\mathcal A_{\mathrm{res}}[\alpha(T)]
+
\int_0^T
\|\mathcal L\alpha(\tau)\|^2_{L^2}
d\tau
=
\mathcal A_{\mathrm{res}}[\alpha_0].
$$

Consequently,

$$
S_{\mathrm{res}}(T)
=
S_{\mathrm{res}}(0)
+
\gamma
\int_0^T
\|\mathcal L\alpha(\tau)\|^2_{L^2}
d\tau
$$

is monotone in operational time. This supplies the mathematical closure of the residual clock-sector entropy-production theorem in the canonical Hodge-coercive model.

The numerical companion implements the diagnostic layer of the theory as a reproducible atlas. It includes one-mode residual relaxation, periodic \(L^2\) field relaxation, a numerical validation ledger for the Lyapunov identity, residual clock-drift and dissipation correlation, Gaussian residual dephasing envelopes, primordial-spectrum diagnostic templates, and a pre-Boltzmann angular-placement proxy.

The CMB transfer note performs the next computational step. It propagates the residual clock-emergence primordial template

$$
P_\zeta(k)
=
A_s
\left(\frac{k}{k_0}\right)^{n_s-1}
\left[
1+\epsilon_{\mathrm{clock}}F_{\mathrm{clock}}(k)
\right]
$$

with

$$
F_{\mathrm{clock}}(k)
=
\exp\left[
-\frac{\log^2(k/k_\ast)}{2\sigma_\ast^2}
\right]
$$

through a CAMB Boltzmann-transfer pipeline to obtain

$$
P_\zeta(k)
\Longrightarrow
C_\ell^{TT}, C_\ell^{TE}, C_\ell^{EE}.
$$

The CMB note includes CAMB settings, baseline cosmological parameters, a seven-case residual clock-feature grid, \(TT\) and \(EE\) fractional transfer-response curves, \(TE\) absolute-response curves, linear-response and sign-symmetry validation checks, and a proxy-to-transfer morphology comparison.

The compact structure of the v1.0 package is

$$
\text{closed residual clock-sector theorem}
\Longrightarrow
\text{monotone entropy-production law}
\Longrightarrow
\text{reproducible numerical diagnostic atlas}
\Longrightarrow
\text{CAMB transfer-level CMB signatures}.
$$

This package should be read as a theorem-and-diagnostic framework for the time arrow in a residual clock sector. The mathematical closure note proves the well-posed Hodge-coercive gradient-flow version of the residual entropy-production theorem. The numerical companion makes the diagnostic targets explicit and reproducible. The CMB transfer note moves the primordial clock-feature template from pre-Boltzmann visualization to transfer-level \(TT\), \(TE\), and \(EE\) diagnostic curves.

The CMB transfer calculation is transfer-level rather than likelihood-level: it computes the response of \(C_\ell^{TT}\), \(C_\ell^{TE}\), and \(C_\ell^{EE}\) under fixed background parameters. It does not infer posterior constraints on \((\epsilon_{\mathrm{clock}},k_\ast,\sigma_\ast)\), and it does not claim a CMB anomaly. Likelihood-level comparison with Planck, ACT, or SPT data is the natural next stage.
