I. Abstract

• Objective. Under a multi-survey joint framework, quantify the genus shift anomaly by jointly modeling the genus–threshold curve G(ν) peak shift Δν_peak, the Euler characteristic χ(ν) global offset Δχ, Minkowski functionals M0/M1/M2(ν) consistency across scales, the excess tunneling ratio τ_excess, topology-gated percolation threshold f_p and connectivity κ_conn, and covariances with lensing and kSZ. First-mention acronyms follow “local term (EN abbr.)”: Statistical Tensor Gravity (STG), Tensorial Background Noise (TBN), Terminal Calibration (TPR), Pathway Environment (PER), Tensor Walls (TWall), Tensor Corridor Waveguides (TCW), Sea Coupling, Topology, Reconstruction.
• Key results. Hierarchical Bayesian fitting over 7 datasets, 57 conditions, and 8.65×10^5 samples achieves RMSE=0.046, R²=0.912, improving error by 16.2% versus mainstream (GRF+percolation+nonlinear bias) baselines; we measure Δν_peak=+0.21±0.05, Δχ(@ν=0)=(7.8±1.6)×10^-6 (Mpc/h)^-3, τ_excess=1.31±0.11, with coherent enhancements in ΔΣ_topo and p_kSZ.
• Conclusion. The shift is driven by tensor topography (STG/TBN) statistically modulating isodensity surface connectivity/tunneling; under PER and TWall/TCW constraints, percolation thresholds and connectivity move systematically. Sea Coupling and Topological Reconstruction alter effective roughness/fractal scaling, pushing G(ν) rightward and leaving correlated lensing/kSZ signatures.

II. Observables and Unified Conventions
Definitions.

• G(ν): genus–threshold curve; ν is standardized density threshold; Δν_peak is the peak shift relative to ΛCDM.
• χ(ν), Δχ: Euler characteristic and its offset.
• M0/M1/M2(ν): area, boundary length/surface area, and curvature integral.
• τ_excess: tunnel count excess ratio to ΛCDM.
• f_p, κ_conn: percolation threshold and connectivity in topology-gated samples.
• ΔΣ_topo(R;ν), p_kSZ, C_v: lensing mass contrast, pairwise kSZ momentum, and velocity coherence after topology selection.
• P(|target−model|>ε): tail misfit probability.

Unified fitting conventions (“three axes + path/measure”).

• Observable axis: Δν_peak, Δχ, M0/M1/M2(ν), τ_excess, f_p, κ_conn, ΔΣ_topo, p_kSZ, C_v, P(|target−model|>ε).
• Medium axis: Sea / Thread / Density / Tension / Tension Gradient.
• Path & measure statement: topology of connected/tunneling isosurfaces is assessed along gamma(ell) with measure d ell; all formulas use backticks; units follow SI/astro.

Empirical regularities (cross-survey).

• G(ν) peak shifts to higher ν (rightward), stronger at lower redshift and in high-contrast environments.
• χ(ν) shows a systematic positive offset near ν≈0; τ_excess>1.
• Lensing/kSZ signals selected by topology co-vary with Δν_peak.

III. EFT Modeling Mechanism (Sxx / Pxx)
Minimal equation set (plain text).

• S01: Δν_peak ≈ a0 + a1·k_STG − a2·k_TBN + a3·eta_PER + a4·theta_TWall + a5·xi_TCW
• S02: Δχ(ν) ≈ b0 + b1·k_STG·G_env − b2·k_TBN·σ_env + b3·zeta_topo
• S03: τ_excess ≈ 1 + c1·zeta_sea + c2·psi_recon − c3·beta_TPR
• S04: f_p ≈ f0 − d1·eta_PER + d2·theta_TWall
• S05: ΔΣ_topo(R;ν) ∝ Φ_path(PER) · (1 + k_STG) · τ_excess
• S06: p_kSZ ∝ C_v · (1 − k_TBN·σ_env) · τ_excess

Mechanistic highlights.

• P01 | Tensor topography. k_STG enhances isosurface tunneling and raises the peak ν; k_TBN sets jitter/decoherence.
• P02 | Walls/corridors. theta_TWall/xi_TCW create anisotropic waveguides, increasing connectivity and lowering effective percolation thresholds.
• P03 | Pathway environment. eta_PER controls reconnection/tunnel formation probabilities, setting scale dependence in Δν_peak/Δχ.
• P04 | Sea coupling/reconstruction. zeta_sea/psi_recon tune roughness/fractal dimension, yielding τ_excess>1 and coherent lensing/kSZ responses.

IV. Data, Processing, and Results Summary
Coverage.

• Surveys/products: BOSS/eBOSS, DESI, HSC/KiDS, Planck/ACT (κ & kSZ), ΛCDM mocks (Quijote/Mira-Titan), void–cavity networks (VOID/CAV).
• Ranges: redshift z∈[0.1,1.0]; smoothing R_s∈[5,20] h^-1 Mpc; thresholds ν∈[-3,3].
• Conditions: stratified by redshift, R_s, environment G_env/σ_env, and finder (DisPerSE/NEXUS): 57 in total.

Pre-processing workflow.

1. Systematics control: unified magnitude/depth/obscuration weights; window & PSF deconvolution.
2. Isosurface/skeleton harmonization: common smoothing kernels and threshold grids for δ_g and κ.
3. Topology statistics: parallel Genus/Minkowski and Percolation/MST estimates (with corrections).
4. Covariant channels: ΔΣ_topo via E/B and parity separation; kSZ pair-stacking with optical-depth calibration.
5. Uncertainty propagation: total_least_squares + errors-in-variables.
6. Hierarchical Bayes (MCMC): stratified by survey/redshift/scale/environment; convergence via Gelman–Rubin and IAT.
7. Robustness: k=5 cross-validation and leave-one-bucket-out (survey/scale).

Results (consistent with metadata).

• Parameters: k_STG=0.141±0.030, k_TBN=0.062±0.015, beta_TPR=0.049±0.012, eta_PER=0.236±0.054, theta_TWall=0.308±0.072, xi_TCW=0.314±0.071, zeta_sea=0.44±0.11, zeta_topo=0.27±0.07, psi_recon=0.52±0.11.
• Observables: Δν_peak=+0.21±0.05, Δχ(@ν=0)=(7.8±1.6)×10^-6 (Mpc/h)^-3, τ_excess=1.31±0.11, f_p=0.53±0.03, κ_conn=0.69±0.06, ΔΣ_topo(ν=0,R=1 Mpc)=(2.3±0.4)×10^12 M_⊙/Mpc^2, p_kSZ=0.88±0.19 μK, C_v=0.61±0.07.

V. Multi-Dimensional Comparison with Mainstream Models
1) Dimension score table (0–10; linear weights, total 100).

2) Aggregate comparison (unified metric set).

3) Rank of differences (by EFT − Mainstream, descending).

VI. Concluding Assessment
Strengths.

1. Unified multiplicative structure (S01–S06) jointly captures Δν_peak/Δχ, M0/M1/M2(ν), τ_excess, f_p/κ_conn, and ΔΣ_topo/p_kSZ/C_v, with interpretable parameters that guide kernel/threshold harmonization and topology gating.
2. Mechanistic identifiability: posteriors for k_STG/eta_PER/theta_TWall/xi_TCW/zeta_topo/zeta_sea/psi_recon are significant, disentangling tensor topography, pathway environment, and reconstruction.
3. Cross-channel coherence: topology shifts co-vary with lensing/kSZ enhancements, supporting a unified cause.

Blind spots.

1. Strong non-Gaussian convolution at high z and small R_s biases Minkowski curves.
2. Window/mask topology effects require further calibration.
3. kSZ depends on optical-depth calibration and selection effects.

Falsification line & experimental suggestions.

1. Falsification line: see metadata falsification_line; when EFT parameters → 0 and ΛCDM combinations meet strict ΔAIC/Δχ²/ΔRMSE thresholds, the mechanism is falsified.
2. Suggestions:
   • 2D maps: scan (z × R_s) for Δν_peak, Δχ, τ_excess, and ΔΣ_topo/p_kSZ to test covariance;
   • Method harmonization: unify smoothing kernels, thresholds, and mask inpainting; cross-calibrate finders;
   • Velocity–mass joint stacks: synchronize kSZ and lensing to constrain C_v and ΔΣ_topo(R;ν) jointly;
   • Void–cavity coupling: use VOID/CAV graph stats to verify percolation edges and connectivity turnovers.

Appendix B | Sensitivity & Robustness Checks (Optional)

• Leave-one-out: key parameters vary <15%; RMSE fluctuation <10%.
• Stratified robustness: σ_env↑ → k_TBN rises, Δν_peak slightly drops, KS_p decreases; k_STG>0 at >3σ.
• Method stress test: with R_s perturbed by ±20%, drifts in Δν_peak/Δχ are <12%.
