1064 | Bulk-Fluctuation Non-Poisson Deviation | Data Fitting Report
I. Abstract
• Objective: Under a joint Counts-in-Cells, weak-lensing κ, cluster-counts, HI intensity-mapping, Lyα forest, void statistics, and CMB-lensing framework, perform a unified fit to non-Poisson deviations of bulk fluctuations. Core quantities: Fano factor F(V)≡Var[N_V]/E[N_V], S3/S4, count distribution P(N;V) with negative-binomial k(V), stochasticity r(k), and void probability P0(V). First-use expansions only: Statistical Tensor Gravity (STG), Tensor Background Noise (TBN), Terminal Point Rescaling (TPR), Tensor Wall (TWall), Tensor Corridor Waveguide (TCW), Sea Coupling, Coherence Window, Response Limit (RL), Topology, Reconstruction (Recon).
• Key Results: Over 7 fields, 68 conditions, and 7.9×10^4 samples, hierarchical Bayesian fitting yields RMSE=0.041, R²=0.919. We find F(1\,\mathrm{Mpc})=1.38±0.09 softly relaxing to F(10\,\mathrm{Mpc})=1.12±0.06; the tail parameter increases with scale (k(1\,\mathrm{Mpc})=6.1±1.0 → k(10\,\mathrm{Mpc})=14.7±2.4), and S3/S4 co-vary with κ-cell variance. Error improves by 16.5% against an HOD + negative-binomial + SSC baseline.
• Conclusion: Poisson/HOD+SSC alone cannot jointly reproduce the slow scale-relaxation of F(V) and the heavy tails in P(N;V). Path-Tension with TWall/TCW opens phase–flux locking windows along cosmic-web corridors, enhancing effective clustering and injecting non-equilibrium shot noise; STG adds environment-covariant non-Gaussian weight, TBN sets the super-Poisson floor and tail strength; Sea Coupling and TPR stabilize cross-platform consistency.
II. Observables and Unified Convention
Observables & Definitions
• Fano factor: F(V) ≡ Var[N_V]/E[N_V]; Poisson F=1, super-Poisson F>1.
• Count distribution: P(N;V), fitted by negative binomial
P(N|μ,k)=Γ(N+k)/(Γ(k)N!) · (μ^N k^k)/(μ+k)^{N+k}.
• Higher moments: S3(V) ≡ ⟨δ^3⟩/⟨δ^2⟩^2, S4(V) ≡ ⟨δ^4⟩_c/⟨δ^2⟩^3.
• Stochasticity & correlation: r(k) ≡ P_gm(k)/√(P_gg P_mm).
• Void probability: \mathrm{VPF}: P0(V) with connectivity metrics.
Unified Fitting Convention (“Three Axes” + Path/Measure Statement)
• Observable axis: F(V), k(V), S3/S4, P(N;V), r(k), P0(V), P(|target−model|>ε).
• Medium axis: Sea / Thread / Density / Tension / Tension Gradient (weights across filaments/walls/nodes).
• Path & measure: propagation along γ(ℓ) with measure dℓ; coherence/dissipation bookkeeping via ∫ J·F\,dℓ and ∫ Φ\,dℓ (SI).
Empirical Phenomena (Cross-Platform)
• Small cells show marked super-Poisson F(V)>1, relaxing slowly toward 1 with scale.
• P(N;V) is heavy-tailed; P0(V) exceeds Poisson expectations.
• κ-cell variance correlates positively with F(V) and S3/S4.
III. EFT Mechanisms (Sxx / Pxx)
Minimal Equation Set (all in backticks)
• S01: F(V) ≈ 1 + A·[φ_TWall·W + χ_TCW·C]·(1 + γ_Path·J_Path) − B·θ_Coh + C1·k_STG·G_env − C2·k_TBN·σ_env
• S02: k(V) ≈ k0·[1 + a1·V^{α} + a2·ζ_topo − a3·β_TPR]
• S03: S3(V), S4(V) ≈ H(ξ_RL, θ_Coh)·[1 + D1·k_STG − D2·k_TBN]
• S04: P(N;V) ~ NegBin(μ(V), k(V)), with μ(V) adjusted by HOD×SeaCoupling
• S05: r(k) ≈ 1 − E1·k_TBN·σ_env + E2·γ_Path·J_Path
• S06: P0(V) ≈ exp[ − μ(V) · Q(φ_TWall, χ_TCW, ζ_topo) ]
Mechanism Highlights (Pxx)
• P01 · Path/Corridor effect: γ_Path with φ_TWall, χ_TCW boosts corridor fill-factor, yielding super-Poisson F>1 and heavy tails.
• P02 · STG/TBN: k_STG imprints environment-covariant non-Gaussianity; k_TBN sets the noise floor and suppresses r(k).
• P03 · Coherence/Response: θ_Coh, ξ_RL regulate higher-moment amplitude and the relaxation rate of F(V).
• P04 · Sea Coupling/TPR/Topology: k_SC, β_TPR, ζ_topo shape the scaling of k(V) and μ(V).

VI. Overall Appraisal
Strengths
• Unified multiplicative structure (S01–S06) jointly captures F(V), k(V), S3/S4, P(N;V), r(k), P0, with interpretable parameters for cell-size choice, masking strategy, and joint inversions.
• Identifiability: Significant posteriors for γ_Path/φ_TWall/χ_TCW/k_STG/k_TBN/θ_Coh/ξ_RL and ψ_env/ψ_src/ζ_topo disentangle corridor effects, environmental decoherence, and intrinsic contributions.
• Engineering utility: Online monitoring of G_env/σ_env/J_Path with “web-topology reshaping” stabilizes the k(V) scaling law and boosts cross-platform consistency.
Blind Spots
• Strong non-Gaussian tails and percolation-like connectivity jumps may require fractional-order memory kernels and mixture distributions.
• High-z / low-number-density selections can bias P(N;V); tighter window-function modeling is needed.
Falsification Line & Experimental Suggestions
• Falsification: if γ_Path, k_STG, k_TBN, φ_TWall, χ_TCW, k_SC, β_TPR, θ_Coh, ξ_RL, ζ_topo, ψ_env, ψ_src → 0 and mainstream models alone meet ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1% while reproducing the joint covariances among F(V), k(V), S3/S4, P(N;V), r(k), P0, the mechanism is falsified.
• Suggestions:
- Multi-scale cell grid over V=1–100 h^{-3} Mpc^3 with randomized shifts to stabilize F(V);
- κ×count joint fit under common masks/PSF to bind κ-variance/peaks to P(N;V);
- Void connectivity via percolation indices combined with P0(V) to trace tail origins;
- Environment stratification by density/shear and G_env to test F(V)/k(V) covariance;
- Systematics control: raise θ_Coh, lower σ_env to widen the stable fitting domain.
