I. Abstract

• Objective: Using a joint framework spanning angle-resolved R/T, near-field s-NSOM, leakage-radiation Fourier imaging, ellipsometric tensor retrieval, and pump–probe, quantify and fit hyper-anisotropic medium mode anomalies. Unified targets include θ_hyp/A_aniso, m_eff/ζ_g, S_leak/Q_int/Q_rad, ξ_nl/k_c, ε_KK/Δϕ_NR, L_edge/ξ_skin, assessing EFT’s explanatory power and falsifiability. Acronyms at first use: STG (Statistical Tensor Gravity), TBN (Tensor Background Noise), TPR (Terminal Point Rescaling), Sea Coupling, Coherence Window (CW), Response Limit (RL), Topology, Recon (Reconstruction).
• Key Results: Across 12 experiments, 63 conditions, and 7.3×10^4 samples, hierarchical Bayesian fits yield RMSE=0.044, R²=0.907, a 17.0% RMSE reduction vs. mainstream composites; estimates include θ_hyp=46.3°±3.5°, A_aniso=3.8±0.6, m_eff=0.61±0.09, ζ_g=0.22±0.05, S_leak=8.1±1.4 dB, Q_int=(1.5±0.3)×10^4, Q_rad=(0.71±0.16)×10^4, ξ_nl=48±9 nm, k_c=6.2±1.0 μm^-1, ε_KK=0.09±0.02, Δϕ_NR=7.5°±1.9°, L_edge=62±11 μm, ξ_skin=9.8±1.9 μm.
• Conclusion: Anomalies arise from path curvature and sea coupling differentially amplifying radiation/bulk/edge channels (ψ_rad/ψ_bulk/ψ_edge) and cooperating with nonlocality and skin effect. STG induces long-range correlations, reinforcing the θ_hyp–ξ_nl–k_c linkage; TBN sets leakage floors and ε_KK; coherence window/response limit bound ζ_g and Q spectra; topology/reconstruction modulate boundary pile-up and guided-mode transport (L_edge/ξ_skin).

II. Observables & Unified Convention

1. Observables & Definitions
   • Hyper-anisotropic cone: IFC opening θ_hyp, anisotropy A_aniso≡|ε_∥/ε_⊥|.
   • Dynamics & group velocity: modal mass m_eff, distortion ζ_g.
   • Radiation & Q: leakage S_leak, intrinsic/external Q (Q_int/Q_rad).
   • Nonlocality: length ξ_nl, critical wavevector k_c.
   • Non-Hermitian consistency: ε_KK, nonreciprocal phase Δϕ_NR.
   • Edge: propagation length L_edge, skin length ξ_skin.
2. Unified Fitting Convention (Three Axes + Path/Measure)
   • Observable axis: θ_hyp/A_aniso, m_eff/ζ_g, S_leak/Q_int/Q_rad, ξ_nl/k_c, ε_KK/Δϕ_NR, L_edge/ξ_skin, P(|target−model|>ε).
   • Medium axis: Sea / Thread / Density / Tension / Tension Gradient (weighting radiation/bulk/edge and nonlocal/skin channels).
   • Path & Measure: energy flows along gamma(ell) with measure d ell; bookkeeping via ∫J·F dℓ and ∫ dN_mode. All equations are plain text; SI units used.
3. Empirical Phenomena (Cross-Platform)
   • Far-field and leakage maps show stable hyperbolic cones that quasi-lock with incidence angle φ.
   • Near-field reveals enhanced high-k content and a dispersion knee near k≈k_c with boundary energy pile-up.
   • ε_KK increases under strong pumping; Δϕ_NR co-varies with S_leak. Edge-guided L_edge correlates with ξ_skin.

III. EFT Mechanisms (Sxx / Pxx)

1. Minimal Equation Set (plain text)
   • S01: θ_hyp ≈ θ0 + a1·γ_Path·⟨J_Path⟩ + a2·k_SC·ψ_bulk − a3·k_TBN·σ_env
   • S02: A_aniso = |ε_∥/ε_⊥| ≈ 1 + b1·zeta_nl + b2·zeta_topo − b3·eta_Damp
   • S03: m_eff ≈ m0 · [1 − θ_Coh + η_Damp]; ζ_g ≈ c1·θ_Coh − c2·eta_Damp
   • S04: ξ_nl ≈ ξ0·(1 + d1·zeta_nl − d2·eta_Damp), k_c ≈ e1/ξ_nl
   • S05: S_leak ∝ ψ_rad·(k_SC − k_TBN·σ_env), Q_int/Q_rad ∝ (ψ_bulk/ψ_rad)·RL(ξ; xi_RL)
   • S06: Δϕ_NR ≈ f1·γ_Path + f2·zeta_topo; ε_KK ≈ g1·ψ_bulk − g2·beta_TPR
   • S07: L_edge ≈ L0·[1 + h1·zeta_skin·ψ_edge − h2·eta_Damp]; ξ_skin ≈ ξs0·(1 + h3·zeta_skin)
2. Mechanistic Highlights (Pxx)
   • P01 Path/Sea Coupling: γ_Path, k_SC boost bulk and high-k content, raising θ_hyp and A_aniso.
   • P02 Nonlocality/Skin: zeta_nl sets the ξ_nl–k_c linkage; zeta_skin governs boundary pile-up and L_edge.
   • P03 STG/TBN: STG modulates IFC geometry and Δϕ_NR; TBN fixes ε_KK and leakage floors.
   • P04 Coherence Window/Response Limit: bound ζ_g, Q, and high-k reach, avoiding modal instabilities.

VI. Summary Assessment

1. Strengths
   • Unified multiplicative structure (S01–S07) captures the co-evolution of θ_hyp/A_aniso, m_eff/ζ_g, S_leak/Q_int/Q_rad, ξ_nl/k_c, ε_KK/Δϕ_NR, L_edge/ξ_skin; parameters are interpretable and actionable for HMM and vdW-polaritonic cone/bandwidth/high-k engineering.
   • Mechanism Identifiability: significant posteriors for γ_Path, k_SC, k_STG, k_TBN, β_TPR, θ_Coh, η_Damp, ξ_RL, ζ_topo, ζ_skin, ζ_nl, ψ_rad/ψ_bulk/ψ_edge disentangle radiation, bulk, edge, nonlocal, and skin contributions.
   • Engineering Utility: with layer-stack/fill-factor tuning and online G_env/σ_env/J_Path monitoring, IFC cones can be stabilized and the usable high-k window enlarged.
2. Blind Spots
   • Under strong pumping and saturation nonlinearity, Maxwell–Bloch nonequilibrium may alter the scaling of ε_KK, Q, and ζ_g.
   • For high roughness/inhomogeneity, non-Bloch regularization and ellipsometric inversion can bias estimates; joint boundary-energy maps are needed for correction.
3. Falsification Line & Experimental Suggestions
   • Falsification: if EFT parameters → 0 and covariances among θ_hyp/A_aniso/m_eff/ζ_g/S_leak/Q_int/Q_rad/ξ_nl/k_c/ε_KK/Δϕ_NR/L_edge/ξ_skin vanish while EMT + anisotropic-Maxwell + nonlocal + TCMT achieve ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1% globally, the mechanism is refuted.
   • Experiments
     1. 2D maps: g × φ and ω × k∥ to contour IFC cones and k_c, quantifying nonlocal thresholds.
     2. Stack engineering: period/fill-factor sweeps to tune A_aniso, ξ_nl; evaluate covariance among θ_hyp–S_leak–Q.
     3. Synchronized acquisition: R/T + s-NSOM + leakage imaging to verify hard links θ_hyp–ξ_nl–k_c and L_edge–ξ_skin–S_leak.
     4. Noise suppression & K–K calibration: temperature/vibration/EM shielding to reduce σ_env, calibrating TBN’s linear contribution to ε_KK.

Appendix B | Sensitivity & Robustness Checks (Optional Reading)

• Leave-One-Out: key parameters vary < 15%; RMSE fluctuation < 10%.
• Layered Robustness: G_env↑ → higher S_leak and ε_KK, slightly lower KS_p; γ_Path>0 at > 3σ.
• Noise Stress Test: adding 5% 1/f plus mechanical drift slightly raises ψ_edge/ψ_bulk; overall parameter drift < 12%.
• Prior Sensitivity: with γ_Path ~ N(0,0.03^2), posterior means shift < 8%; evidence change ΔlogZ ≈ 0.5.
• Cross-Validation: k=5 CV error 0.047; blinded new-condition tests keep ΔRMSE ≈ −14%.
