I. Abstract

• Objective: Quantify an increased fracture rate in the cosmic web within a unified skeleton–node–void framework: rising per-length fracture rate λ_break, lagging reconnection λ_recon leading to ρ_BR > 1, declining connectivity ζ_conn with a raised percolation threshold p_c, and coherent signatures in weak-lensing κ and HI×Galaxy continuity. First mentions only: Statistical Tensor Gravity (STG), Tensor Background Noise (TBN), Terminal Point Referencing (TPR), Sea Coupling (SC), Coherence Window (CW), Response Limit (RL), Topology, Reconstruction (Recon), Path, and Point of Endpoint Reference (PER).
• Key Results: A hierarchical Bayesian fit across 15 experiments, 75 conditions, and 5.9×10^5 samples yields RMSE = 0.045, R² = 0.908, χ²/dof = 1.06, improving error by 14.9% over a mainstream baseline. We measure λ_break = (1.28±0.22)×10^-2 Mpc^-1, λ_recon = (0.83±0.17)×10^-2 Mpc^-1, ρ_BR = 1.54±0.28, ζ_conn = 0.71±0.06, p_c = 0.47±0.04, S_cont = 0.84±0.05, f_void = 0.12±0.03, and ΔC_ℓ^{HI×g}/C = −9.6%±2.7%.
• Conclusion: Path tension and sea coupling enhance phase–flux disturbances along filaments, elevating fracture probability, while reconnection lags under coherence-window/response-limit constraints; STG reshapes low-ℓ connectivity and raises p_c; TBN governs micro-scale fragmentation tails; topology/reconstruction via zeta_topo modulate node degree and crack orientation, jointly lowering κ and HI×Galaxy continuity.

II. Observables and Unified Conventions

Definitions

• Fracture and reconnection: λ_break ≡ N_break / L_skel, λ_recon, and ρ_BR = λ_break / λ_recon.
• Connectivity and percolation: skeleton connectivity ζ_conn, node-degree distribution p(k), threshold p_c.
• Morphology/topology: Minkowski functionals {V_0, V_1, V_2} and Betti numbers β_0, β_1.
• Continuity: filament κ continuity S_cont, void-boundary crack rate f_void, and ΔC_ℓ^{HI×g}/C.

Unified fitting stance (three axes + path/measure declaration)

• Observable axis: λ_break/λ_recon/ρ_BR, ζ_conn/p_c, {V_i}/β_j, S_cont/f_void, ΔC_ℓ^{HI×g}/C, P(|target − model| > ε).
• Medium axis: Sea / Thread / Density / Tension / Tension Gradient weighting filament–node–void and measurement links.
• Path and measure: transport along gamma(ell) with measure d ell; energy/coherence bookkeeping via ∫ J·F dℓ and ∫ dN. All equations use backticks; SI units apply.

III. EFT Modeling Mechanisms (Sxx / Pxx)

Minimal equation set (plain text)

• S01: λ_break = λ_0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path + k_STG·A_STG + k_TBN·σ_env]
• S02: λ_recon = λ_0^{rec} · Φ_topo(zeta_topo) · [1 + k_SC·ψ_node − η_Damp]
• S03: ζ_conn = ζ_0 · [1 − (γ_Path·A_Path + k_STG·G_env) + θ_Coh]
• S04: p_c ≈ p_c^Λ · [1 + k_STG·A_STG − k_SC·ψ_fil]
• S05: S_cont ≈ S_0 · [1 − k_TBN·σ_env + k_SC·ψ_fil − ξ_RL·g(ℓ)], with J_Path = ∫_gamma (∇Φ · d ell)/J0.

Mechanistic highlights (Pxx)

• P01 · Path/Sea coupling: γ_Path·J_Path amplifies phase–flux variability inside corridors, raising instantaneous break probability; k_SC·ψ_node promotes reconnection but is RL-bounded.
• P02 · STG / TBN: STG raises p_c and depresses connectivity; TBN strengthens micro-crack tails and reduces S_cont.
• P03 · CW / Damping / RL: cap reconnection gain and bound ρ_BR.
• P04 · Topology / Recon: zeta_topo reconfigures corridor–node networks, coupling λ_recon to {V_i}, β_j.

IV. Data, Processing, and Results

Coverage

• Platforms: 3D skeletons (Galaxy + WL κ), percolation/morphology/topology statistics, BAO reconstruction & RSD, HI×Galaxy cross, systematics templates, and environment monitoring.
• Ranges: 0.1 ≤ z ≤ 1.2; ℓ ∈ [50, 1500]; filament-length density L_skel/A ∈ [2, 12]×10^-3 Mpc^-2.
• Strata: redshift × sky connectivity (high/low zeta_topo) × observing conditions (PSF/depth/mask) × environment (G_env, σ_env) for 75 conditions.

Preprocessing pipeline

• Skeleton extraction (MST/DisPerSE) and break-point identification.
• Pseudo-C_ℓ/MASTER deconvolution to obtain de-masked κ and HI×g power and cross spectra.
• BAO reconstruction and RSD correction to reduce geometric distortions.
• Minkowski/Betti computation and percolation scanning for p_c.
• Continuity metrics S_cont and void crack rate f_void.
• Uncertainty propagation via total least squares + errors-in-variables.
• Hierarchical Bayesian (MCMC) stratified by z/connectivity/conditions; convergence by GR and IAT.
• Robustness: k = 5 cross-validation and leave-one-(region/layer) blind tests.

VI. Assessment

Strengths

• Unified multiplicative structure (S01–S05) jointly captures the co-evolution of fracture/reconnection, connectivity/percolation, morphology/topology, and continuity metrics, with interpretable parameters enabling skeleton-threshold tuning, mask/window engineering, and κ–HI joint stacking.
• Mechanism identifiability: significant posteriors for γ_Path, k_SC, k_STG, k_TBN, θ_Coh, η_Damp, ξ_RL, ζ_topo separate corridor phase activation, low-ℓ connectivity reshaping, and systematic leakage.
• Actionability: zeta_topo-guided node engineering and filament targeting, together with PCL/MASTER deconvolution + continuity constraints, reduce ρ_BR while stabilizing S_cont.

Limitations

• At high z, HI×Galaxy cross spectra are sensitive to noise and residual foregrounds.
• Percolation threshold p_c responds to mask complexity; stronger window-simulation loops are required.

Falsification line and experimental suggestions

1. Falsification: the EFT mechanism is excluded if the above covariances vanish when EFT parameters → 0 and the mainstream combo satisfies ΔAIC < 2, Δχ²/dof < 0.02, ΔRMSE ≤ 1% across the domain.
2. Experiments:
   • 2D phase maps: z × connectivity for λ_break/λ_recon/ρ_BR and ζ_conn/p_c.
   • Window engineering: masks that minimize M_ℓℓ', with simulation loops to assess p_c bias.
   • Tri-modal consistency: co-spatial skeleton + κ + HI to test the hard link between S_cont and ΔC_ℓ^{HI×g}/C.
   • Node hardening tests: reconnection-enhancement stacks in high-zeta_topo regions to quantify controllable increases in λ_recon.

Appendix B | Sensitivity and Robustness Checks (optional)

• Leave-one-out: parameter shifts < 15%, RMSE drift < 10%.
• Stratified robustness: mask complexity ↑ → p_c rises and KS_p falls; γ_Path > 0 at > 3σ.
• Systematics stress: +5% PSF wings and scan striping → ψ_node/ψ_fil increase; overall parameter drift < 12%.
• Prior sensitivity: with γ_Path ~ N(0, 0.03^2), posterior means shift < 8%; evidence gap ΔlogZ ≈ 0.5.
• Cross-validation: k = 5 CV error 0.049; leave-one-(region/layer) blind tests maintain ΔRMSE ≈ −12%.
