Notation & objects

Meta-Manifold (MM): a compact, orientable, smooth 10-manifold with metric \(g_{\mathrm{MM}}\) and volume form \(d\mu_{\mathrm{MM}}\).
Projection map: \(\pi:\;\mathrm{MM}\to \mathbb{R}^{3,1}\) (topological surjection).
Kernel: \(K_{\lambda}(x;X)\ge 0\) with resolution parameter \(\lambda\) (our slice takes \(\lambda=\lambda_q\)).
Fields: MM fields \(\Phi\) (bundles suppressed); 4D observables \(O\).
Invariants (empirical): \(\lambda_q\) (resolution), locality radius, regularity/positivity (PSD), effective spectral exponent \(D_{\mathrm{eff}}\).
Focusing measures: projection-Jacobian average \(A(x)\!\sim\!\langle J_\pi^{-1}\rangle\); microstate multiplicity \(M(\lambda,\varepsilon;x)\); Complexity/Projection Index \(\mathrm{CPI}(x)=\log_{10} M\).

Push-forward definition

4D observables are push-forwards of MM fields via the kernel (finite resolution):

O(x)=\int_{\mathrm{MM}} K_{\lambda}(x;X)\,\Phi(X)\,d\mu_{\mathrm{MM}}(X),\qquad \lambda=\lambda_q.

Only invariants of the kernel class are empirical; the detailed functional form of \(K\) is not identified by data.

Linearity & boundedness. \(\mathcal{K}_{\lambda}: L^2(\mathrm{MM})\to L^2(\mathbb{R}^{3,1})\) bounded, linear.

Normalization. Choose \(\int K_{\lambda}(x;X)\,d\mu_{\mathrm{MM}}(X)=1\) so constants map to constants.

PSD. Kernels are positive semidefinite as operators, ensuring stable quadratic forms.

Kernel guardrails (well-posedness)

\textbf{K1 (normalization)}:\quad \int K_{\lambda}(x;X)\,d\mu_{\mathrm{MM}}(X) < \infty.

\textbf{K2 (locality)}:\quad K_{\lambda}(x;X)\text{ sharply peaks for }X\approx \pi^{-1}(x).

\textbf{K3 (monotone fidelity)}:\quad \partial_{\lambda}\alpha(\lambda)\le 0,\ \alpha(\lambda_q)\approx 1.

Examples. Gaussian-like kernels in normal coordinates serve as didactic proxies; forecasts remain kernel-invariant.

S2 — Fidelity & retention law (universal)

Fidelity \(\alpha(\lambda)\in[0,1]\) quantifies retained fine structure at effective scale \(\lambda\). The invariant form is

\alpha(\lambda)=\exp\!\Big[-\big(\tfrac{\lambda}{\lambda_q}\big)^{D_{\mathrm{eff}}}\Big].

Two regimes and a coherence cliff near \(\lambda\!\approx\!\lambda_q\): below—interference-grade invariants retain; above—classical coarse-grain dominates. Empirically read out via, e.g., \(R_{\mathrm{HF}}(\lambda)\) and \(R_{\mathrm{struct}}(\lambda)=\mathrm{corr}^2(e_4|_{\lambda\to0},e_4|_\lambda)\).

Log-law readout. \(\ln(-\ln R)=D_{\mathrm{eff}}\ln\lambda - D_{\mathrm{eff}}\ln\lambda_q\).

Platform mapping. \(\lambda\) depends on modality (baseline, wavelength, coherence length); ratios to \(\lambda_q\) are invariant.

S3 — Structure focusing & CPI (supports S2)

Small projection-Jacobian amplifies measure and stabilizes a web-like skeleton that outlives high-frequency detail; CPI quantifies local microstate budgets.

A(x)\ \sim\ \big\langle J_\pi^{-1}\big\rangle,\qquad M(\lambda,\varepsilon;x)\ \sim\ A(x)\,\big(\tfrac{\lambda}{\varepsilon}\big)^{D_I},\qquad \mathrm{CPI}(x)=\log_{10} M.

Operationally: regions with higher \(A(x)\) exhibit slower decay of \(R_{\mathrm{struct}}\) relative to \(R_{\mathrm{HF}}\), consistent with the retention law.

Coarea link. Focusing follows from the coarea formula; CPI packages the mode-packing with scale and locality.

Effective spectral exponent \(D_{\mathrm{eff}}\)

\(D_{\mathrm{eff}}\) packages asymptotic mode counting without committing to literal fractal geometry. It controls densities and ranked ratios across domains.

Density/Counting. Cumulative retained modes scale as \(N(\Omega)\!\sim\!\Omega^{D_{\mathrm{eff}}}\) with density \(\rho(\Omega)\!\sim\!\Omega^{D_{\mathrm{eff}}-1}\).

Ranked-ratio law (context-free base). For ranked scales \(\{\Omega_n\}\): \(\Omega_n/\Omega_1 = n^{1/D_{\mathrm{eff}}}\). The ratio is invariant; the base \(\Omega_1\) is context-set.

Action-level view (sketch)

Let \(S_{\mathrm{MM}}[\Phi, g_{\mathrm{MM}}]\) encode curvature and fields on MM. Projection induces an effective 4D action in terms of push-forwards \(O\) and kernel invariants.

Variation. Stationarity on MM then push-forward yields Euler–Lagrange-type relations for \(O\). Invariants act as parameters, not dynamical fields.

Forecasts are expressed in invariant language and do not depend on a specific kernel form.

Consistency checklist

Locality in projection: \(K_{\lambda}(x;X)\) concentrated near \(X\approx\pi^{-1}(x)\).
Integrability/PSD: bounded operator with non-negative quadratic form.
Normalization: constants map to constants.
Monotone fidelity: \(\alpha(\lambda)\) non-increasing; critical scale \(\lambda_q\).
Topology interface: stable topological data on MM label 4D classes under projection.
Focusing metrics: \(A(x)\), \(M(\lambda,\varepsilon;x)\), \(\mathrm{CPI}(x)\) consistent with retention readouts.

Worked micro-example (didactic)

Take a scalar \(\Phi\) on MM and a Gaussian proxy kernel with locality radius \(\sigma\):

K_{\lambda}(x;X)\propto\exp\!\Big(-\tfrac{\mathrm{dist}(X,\pi^{-1}(x))^2}{2\sigma^2}\Big),\quad \sigma\sim\lambda.

Then \(O=K_{\lambda}\star\Phi\) is band-limited; high-frequency content is exponentially suppressed with index set by \(\lambda/\lambda_q\), giving the retention law above.

Falsification gates (math form)

S2 — Retention: repeated null of a transition in \(\partial_{\lambda}\alpha\) near the posited \(\lambda_q\) across independent platforms.
Structure vs HF: absence of the predicted separation \(R_{\mathrm{struct}}\) vs \(R_{\mathrm{HF}}\) under the same \((\lambda_q,D_{\mathrm{eff}})\).
Equivariance: symmetry-breaking artifacts attributable to \(K_{\lambda}\) (violating kernel guardrails).

Ranked-ratio checks can support the picture when applicable, but ALP base tests are relegated to speculation (see below).

Notes

“Fractal” is used as an effective spectral exponent (well-posed surrogate), not as a literal non-integer manifold dimension.

S1 (ALP base) is not used as support; S2 is the universal law, S3 strongly supports S2.

Speculative — ALP / non-harmonic ladder (relegated)

Kept for completeness; not used to support the framework. If applicable, the ladder relation is

m_n = m_1\, n^{1/D_{\mathrm{eff}}}.

Hidden when the Speculative toggle is off.
