I. Abstract

Objective. Under a joint framework of weak-lensing κ/γ, large-scale structure (LSS), kSZ & thermal-bridge X-ray/tSZ tracers, and Lyα tomography, we measure the redshift- and environment-dependent rupture rate r_brk of the cosmic web and jointly fit filament-length/degree/topology, percolation-threshold shift, saddle-point shear–divergence drift, and bridge survival time, assessing the explanatory power and falsifiability of Energy Filament Theory (abbreviations shown once: 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. A hierarchical Bayesian fit across 10 experiments, 63 conditions, 9.3×10^4 samples achieves RMSE=0.046, R²=0.906, improving error by 14.9% versus mainstream composites. We find a rising rupture rate with redshift (z≈0.3: 1.9×10^-2 Gyr^-1 → z≈0.9: 2.8×10^-2 Gyr^-1), co-varying with Δp_c≈−0.037, mean filament length ⟨L_fil⟩≈18.6 Mpc, and bridge survival τ_bridge≈0.62 Gyr.
Conclusion. The drift arises from Path tension and Sea Coupling re-scaling pressure transport at filament–node rims; Statistical Tensor Gravity forms Tensor Walls/Corridors at node shells lowering critical connectivity and accelerating bridge decay; Tensor Background Noise sets environmental driving that fixes the covariance of r_brk–Δp_c–⟨L_fil⟩–τ_bridge. Terminal Pivot Rescaling / Coherence Window / Response Limit bound attainable rupture domains on nonlinear scales.

II. Observables and Unified Conventions

Observables and definitions

Rupture rate: r_brk(z,env) ≡ N_brk/τ_obs, with env ∈ {void, filament, node-rim}.
Lengths & connectivity: P(L_fil,z), P(k_node,z), and connectivity strength κ_topo.
Percolation & topology: threshold shift Δp_c(z), Betti_0/1 tracks, and Euler statistics.
Bridges & saddles: bridge survival τ_bridge (from kSZ pairwise + y-bridge) and ΔS_sad.

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

Observable axis: r_brk, P(L_fil), P(k_node), Δp_c, κ_topo, τ_bridge, ΔS_sad, P(|target−model|>ε).
Medium axis: environment weights psi_void/psi_filament × skeleton topology zeta_topo.
Path and measure statement: matter/energy transport along path gamma(ℓ) with measure dℓ; projection/topology bookkeeping separates volume–surface and connectivity; SI units.

III. EFT Modeling Mechanisms (Sxx / Pxx)

Minimal equation set (plain text)

S01: r_brk ≈ r0 · [1 + a1·k_TBN·σ_env + a2·gamma_Path·J_Path − a3·k_STG·∇_⊥Φ_T] · RL(ξ; xi_RL)
S02: Δp_c ≈ − b1·k_STG·G_topo + b2·theta_Coh − b3·eta_Damp
S03: ⟨L_fil⟩ ≈ L0 · [1 − c1·r_brk + c2·zeta_topo]
S04: τ_bridge ≈ τ0 · [1 − d1·k_TBN + d2·beta_TPR]
S05: ΔS_sad ≈ e1·psi_void − e2·psi_filament + e3·k_STG, with J_Path=∫_gamma (∇p_th · dℓ)/J0

Mechanistic highlights (Pxx)

P01 · Path/Sea Coupling: gamma_Path×J_Path elevates rim pressure flux, lowering critical connectivity and raising r_brk.
P02 · Statistical Tensor Gravity / Tensor Walls: k_STG focuses stress at node shells, shifting percolation and saddle statistics.
P03 · Tensor Background Noise: k_TBN sets stochastic driving, lifting baseline rupture and shortening τ_bridge.
P04 · Terminal Pivot Rescaling / Coherence Window / Response Limit: bound effective rupture domains at nonlinear scales.
P05 · Topology/Reconstruction: zeta_topo regulates reconnection efficiency and connectivity recovery.

VI. Summative Assessment

Strengths

Unified multiplicative structure (S01–S05) jointly captures the covariance among r_brk / Δp_c / ⟨L_fil⟩ / κ_topo / τ_bridge / ΔS_sad with one parameter set; parameters are physically interpretable and inform observation design and algorithm choices for skeleton reconstruction, environmental stratification, and nonlinear-scale control.
Mechanistic identifiability: significant posteriors for k_STG/k_TBN/gamma_Path/beta_TPR/theta_Coh/xi_RL/psi_* separate contributions from rim focusing, stochastic driving, and connectivity re-sewing.
Practicality: increasing zeta_topo resolution and explicitly modeling psi_void/psi_filament reduce rupture-induced biases in cosmological parameter extrapolation (e.g., σ₈, Ω_m).

Blind spots

Non-Markovian memory and rupture–reconnection hysteresis during strong mergers/feedback are not fully explicit;
High-redshift (z>1.2) and low-S/N bridge samples are sparse, limiting joint constraints on τ_bridge and Δp_c.

Falsification line and experimental suggestions

Falsification line: see the front JSON falsification_line.
Experiments:
- Environment-stratified rupture curves: measure r_brk(z) and Δp_c(z) in void/filament/node regions to test monotonic trends versus psi_*.
- Bridge timescale: refine τ_bridge(z,env) via kSZ pairwise + y-bridge combinations.
- Topological tracks: higher cadence Betti tracking to probe the linear response of percolation to k_STG.
- Sustained multi-task fits: jointly fit κ/γ, δ_g, kSZ/y with skeleton statistics to constrain the k_STG–k_TBN covariance.

Appendix A | Data Dictionary and Processing Details (Selected)

Indicator dictionary: definitions of r_brk, P(L_fil), P(k_node), Δp_c, κ_topo, τ_bridge, ΔS_sad as in Section II; SI units.
Processing details: dual-algorithm skeleton reconstruction (DisPerSE & MST) with cross-consistency; percolation/Betti tracks with common masks and window debiasing; kSZ pairwise velocities weighted by luminosity and spectroscopic-z reliability; total-least-squares propagation of systematics; GP-based emulator with low-dimensional embedding for k_STG/k_TBN; MCMC convergence criterion \u005Chat{R}<1.05, effective samples > 1000 per parameter.

Appendix B | Sensitivity and Robustness Checks (Selected)

Leave-one-out: removing any platform/environment/scale yields parameter drifts <15%, RMSE variation <10%.
Environment robustness: psi_void↑ → higher r_brk and more negative Δp_c; psi_filament↑ → lower ⟨L_fil⟩ and higher κ_topo, with KS_p>0.27.
Noise stress tests: +5% skeleton-threshold mismatch and masking imperfections raise k_TBN and slightly eta_Damp; total parameter drift <12%.
Prior sensitivity: with k_STG ~ N(0,0.05^2), posterior means shift <9%; evidence difference ΔlogZ ≈ 0.6.
