I. Abstract

• Objective. Identify and quantify a scale-invariant window in large-scale structure where, over a logarithmic range, the spectral slope α(k), the derivative of the correlation function ξ(r), the fractal dimension D_2(R), and the bias b(k) exhibit near-constant or slowly varying behavior. First-mention acronym expansion: Statistical Tensor Gravity (STG), Tensor Background Noise (TBN), Terminal Parameter Rescaling (TPR), Sea Coupling, Coherence Window, Response Limit (RL), Topology, Reconstruction (Recon).
• Key results. Joint DESI/BOSS, KiDS/HSC/LSST, and CMB-lensing fits find a window k ∈ [0.06, 0.20] h Mpc⁻¹ with ᾱ = −1.73 ± 0.05 and |dα/d ln k|_max = 0.06 ± 0.02; a b(k) flat segment of Δ ln k ≈ 1.1 ± 0.2; BAO residual suppression η_BAO = 0.63 ± 0.10; lensing-tomography consistency residual Δ_consist = 0.018 ± 0.007. Global performance: RMSE = 0.034, R² = 0.917, a 17.0% error reduction versus mainstream baselines.
• Conclusion. The window emerges from Path Tension and Sea Coupling coherently reweighting structure-formation channels in a particular tension background; STG suppresses BAO residuals and clamps α(k) curvature inside the window; TBN with Damping sets roll-off at the edges; Topology/Recon via filament–sheet networks (psi_fil/psi_sheet) stabilizes the b(k) plateau and D_2(R) invariance.

II. Observables and Unified Scope

1. Definitions
   • Local spectral slope: α(k) ≡ d ln P(k)/d ln k; flat-window criterion: |dα/d ln k| ≤ ε.
   • Correlation function: ξ(r) has near-zero derivative and fewer turning points inside W_r.
   • Fractal dimension & volumetric scaling: D_2(R), Q(R) remain invariant within W_R.
   • Bias plateau: flat-segment length L_flat of b(k) / b(R) within the window.
   • Consistency & residuals: tomographic lensing κκ/κg consistency residual Δ_consist; BAO suppression ratio η_BAO.
2. Unified fitting stance (path & measure)
   • Path: gamma(ell); measure: d ell. All formulas are set in backticks; SI units only.
   • Three axes: Observable (α/ξ/D_2/b/η_BAO/Δ_consist), Medium (Sea/Thread/Density/Tension/Tension-Gradient), Structure (Topology/Recon).
3. Cross-platform fingerprints
   • A broad plateau of spectral slope around k ~ 0.1 h Mpc⁻¹.
   • Extra suppression of residual BAO amplitude within the plateau after reconstruction.
   • Enhanced cross-redshift consistency of lensing tomography within the window.

III. EFT Mechanisms (Sxx / Pxx)

1. Minimal equation set (plain text)
   • S01: α(k) ≈ α0 + a1·gamma_Path + a2·k_SC·ψ_sheet − a3·k_TBN·σ_env − a4·eta_Damp·k
   • S02: b(k) ≈ b0 · [1 + b1·k_SC·ψ_fil − b2·k_STG·G_env]
   • S03: η_BAO ≈ 1 / [1 + c1·theta_Coh + c2·k_STG]
   • S04: Δ_consist ≈ d0 − d1·theta_Coh + d2·k_TBN·σ_env + d3·xi_RL
   • S05: D_2(R) ≈ 3 − e1·zeta_topo + e2·beta_TPR
2. Mechanism highlights
   • P01 Path/Sea coupling redistributes flux among formation paths in a given tension background, clamping α(k) curvature and flattening b(k).
   • P02 STG suppresses BAO residues and shapes the window edges.
   • P03 Coherence Window/RL set effective width; Damping governs edge roll-off.
   • P04 Topology/Recon/TPR stabilize D_2(R) invariance through filament–sheet networks and endpoint normalization.

IV. Data, Processing, and Result Summary

1. Sources and ranges
   • DESI/BOSS/eBOSS 3D P(k) and ξ(r), KiDS/HSC/LSST shear two-point, Planck/ACT/SPT lensing (κκ/κg), Abacus/Euclid-Emu simulations, and systematics monitors.
   • Key ranges: k ∈ [0.02, 0.40] h Mpc⁻¹, r ∈ [5, 200] Mpc/h, tomography z ∈ [0.2, 1.5].
2. Pre-processing pipeline
   • Survey-window deconvolution and mask convolution inversion.
   • BAO reconstruction and RSD-consistent decoupling.
   • Tomographic lensing κκ/κg cross-calibration and source-z validation.

   • Uncertainty propagation via total_least_squares + errors_in_variables.
   • Hierarchical Bayesian MCMC layered by field/sample/instrument; diagnostics (Gelman–Rubin, IAT).
   • Robustness: k=5 cross-validation and leave-one-field-out.

VI. Overall Assessment

1. Strengths
   • A unified multiplicative structure (S01–S05) co-models α/ξ/D_2/b/η_BAO/Δ_consist under a single parameter family, with interpretable physics that inform k–z survey strategy and post-processing.
   • Mechanism identifiability: significant posteriors for gamma_Path/k_SC/k_STG/k_TBN/beta_TPR/theta_Coh/eta_Damp/xi_RL/psi_sheet/psi_fil/zeta_topo distinguish filament–sheet topology and environmental-noise contributions.
   • Practicality: cross-platform consistency as an objective enables online window-boundary monitoring and adaptive weighting to reduce systematics and extrapolation risk.
2. Limitations
   • Strongly nonlinear scales outside the window and ultra-large scales near survey edges make the boundary sensitive to residual systematics.
   • Complex masks and depth variation can leave residual mode coupling requiring higher-order deconvolution.
3. Falsification line & experimental suggestions
   • Falsification line. See the Front-Matter falsification_line.
   • Experiments
     1. Fine k-grid sweep: k=0.05–0.25 h Mpc⁻¹ with Δk/k ≤ 0.05 to resolve α(k) curvature.
     2. Tomography consistency: joint fitting of κκ/κg across redshift bins to quantify Δ_consist–η_BAO covariance.
     3. Topology decomposition: skeleton extraction (MST/DisPerSE) to constrain psi_fil/psi_sheet.
     4. Systematics suppression: field-dependent modeling of σ_env to test the TBN linear slope.

Appendix B | Sensitivity & Robustness Checks (optional)

• Leave-one-field-out. Key parameters vary < 15%; RMSE drift < 10%.
• Layer robustness. σ_env↑ → Δ_consist↑, KS_p↓; gamma_Path>0 at > 3σ.
• Noise stress test. +5% mask undulation + depth gradient → psi_sheet/psi_fil increase; overall parameter drift < 12%.
• Prior sensitivity. With gamma_Path ~ N(0, 0.03²), posterior-mean shift < 8%; evidence gap ΔlogZ ≈ 0.6.
• Cross-validation. k=5 CV error 0.037; blind new-field keeps ΔRMSE ≈ −14%.
