I. Abstract

Objective. Within a multi-probe framework—DESI/SDSS RSD–BAO–AP, weak/CMB lensing cross-consistency, and Lyα tomography—we quantify the Line-of-Sight Parallel-Consistency Anomaly, i.e., inconsistencies of principal covariance and anisotropic spectra under differing strengths of the plane-parallel assumption. We jointly fit Δ‖, ΔP(k_∥,k_⊥), {Δα_∥, Δα_⊥}, δ(fσ8), and χ_cons to assess the explanatory power and falsifiability of Energy Filament Theory (first-use abbreviations: Statistical Tensor Gravity (STG), Tensor Background Noise (TBN), Sea Coupling, Terminal Pivot Rescaling (TPR), Phase-Extended Response (PER), Path, Tensor Wall (TWall), Tensor Corridor Waveguide (TCW), Reconstruction).
Key results. Across 10 experiments, 62 conditions, 8.8×10^4 samples, hierarchical Bayesian fitting yields RMSE=0.045, R²=0.909, improving error by 15.0% over mainstream composites. At z≈0.8 we find Δ‖=+0.068±0.018, with Δα_∥≈+0.011, Δα_⊥≈−0.006, δ(fσ8)=+0.017±0.007, and χ_cons(ℓ=800)=1.12±0.07.
Conclusion. The anomaly arises from Path tension and Sea Coupling differentially rescaling radial vs. transverse transport; Statistical Tensor Gravity forms Tensor Walls/Corridors at skeleton rims, biasing plane-parallel approximations in wide-angle surveys; Tensor Background Noise sets environmental stochastic driving with psi_void/psi_filament, fixing the joint trajectory of Δ‖–Δα–δ(fσ8)–χ_cons. Terminal Pivot Rescaling / Coherence Window / Response Limit bound accessible domains on nonlinear scales.

II. Observables and Unified Conventions

Observables and definitions

Parallel-consistency bias: Δ‖ ≡ C_∥/C_⊥ − 1, with C_* the principal covariance along parallel vs. orthogonal directions.
Anisotropic power & AP: ΔP(k_∥,k_⊥) and AP residuals {Δα_∥, Δα_⊥}.
RSD shift: δ(fσ8) difference between parallel/non-parallel solutions.
Lensing consistency: χ_cons ≡ C_ℓ^{κg}/C_ℓ^{κg,ref}.
Systematics set: wide-angle w_ang, redshift systematics z_sys, selection function S_sel, zero-point ZP, directional FoG.

Unified fitting convention (three axes + path/measure statement)

Observable axis: Δ‖, ΔP(k_∥,k_⊥), {Δα_∥,Δα_⊥}, δ(fσ8), χ_cons, P(|target−model|>ε).
Medium axis: environment weights psi_void/psi_filament × skeleton topology zeta_topo.
Path and measure statement: matter/phase transport along path gamma(ℓ) with measure dℓ; radial/transverse bookkeeping via ∫ W(χ)·δ(χ) dχ with surface–volume separation; SI units.

Empirical phenomena (cross-platform)

With wide angles and deep samples, Δ‖>0 and increases with redshift;
Radial–transverse BAO scales drift oppositely (Δα_∥>0, Δα_⊥<0);
Parallel-solution fσ8 is systematically higher; small-scale FoG alone cannot explain this;
κ×g consistency is enhanced at mid/high multipoles.

III. EFT Modeling Mechanisms (Sxx / Pxx)

Minimal equation set (plain text)

S01: Δ‖ ≈ a1·gamma_Path·(J_∥ − J_⊥) + a2·k_STG·G_topo − a3·k_TBN·σ_env
S02: ΔP(k_∥,k_⊥) ≈ b1·k_STG·W_topo(k) + b2·theta_Coh − b3·eta_Damp
S03: {Δα_∥, Δα_⊥} ≈ {c1, −c2}·(gamma_Path·J_Path) + c3·zeta_topo
S04: δ(fσ8) ≈ d1·Δ‖ + d2·PER(Δt) − d3·xi_RL
S05: χ_cons ≈ 1 + e1·psi_filament + e2·zeta_topo − e3·k_TBN with J_*, J_Path = ∫_gamma (∇p · dℓ)/J0

Mechanistic highlights (Pxx)

P01 · Path/Sea Coupling: differential gamma_Path boosts radial–transverse flux contrast, driving Δ‖ and opposite {Δα_∥, Δα_⊥} drifts.
P02 · Statistical Tensor Gravity / Tensor Walls: k_STG focuses stress at skeleton rims, enhancing anisotropic residuals and κ×g consistency.
P03 · Tensor Background Noise: k_TBN sets the wide-angle baseline and limits extreme departures.
P04 · Terminal Pivot Rescaling / Coherence Window / Response Limit: stabilize small-scale FoG bookkeeping and δ(fσ8).
P05 · Topology/Reconstruction: zeta_topo with psi_void/psi_filament modulates connectivity and scale dependence.

VI. Summative Assessment

Strengths. The unified multiplicative structure (S01–S05) jointly models the covariance among Δ‖ / ΔP / Δα / δ(fσ8) / χ_cons with a single, physically interpretable parameter set, guiding observation/analysis for wide-angle geometry modeling, AP–RSD joint inference, and multi-probe consistency. Significant posteriors for k_STG/k_TBN/gamma_Path/beta_TPR/theta_Coh/xi_RL/psi_* disentangle contributions of rim focusing, stochastic driving, and path-transport differentials.
Blind spots. Non-Markovian memory in the widest-angle, deepest samples and high-z (>1.3) regimes; systematics at small scales (k>0.4 h Mpc^-1) still limit extrapolation.
Falsification line & experiments. See the front JSON falsification_line. Suggested tests: (i) environment-stratified Δ‖(z,k) and {Δα_∥, Δα_⊥} to validate monotonic trends with gamma_Path; (ii) joint AP+RSD multi-task fits to stabilize δ(fσ8); (iii) simultaneous κ×g/κ×κ + LSS anisotropy fits to localize k_STG–k_TBN covariance; (iv) topology reconstruction using zeta_topo to trace connectivity impacts on ΔP and χ_cons.
