I. ABSTRACT
Objective: Model strangeness enhancement with a unified multiplicative structure that couples the path term J_Path and sea coupling k_sSea to environment and recombination mechanisms, and perform a hierarchical Bayesian fit across multi-granular observables (K/π, Λ/K0s, Ξ/π, Ω/π, E_s).
Key Results: Jointly fitting 12 experiments, 88 conditions, and 1.06×10^5 samples yields RMSE=0.044, R²=0.898, χ²/dof=1.05—an 18.0% error reduction vs. mainstream (canonical suppression + string/recombination + Cronin). In high-multiplicity pp (top 10%) we obtain E_s = 1.68 ± 0.12; the path slope is dE_s/dJ_Path = 0.41 ± 0.09.
Conclusion: Strangeness enhancement is governed by the multiplicative coupling of the path term gamma_Path·J_Path, Statistical Tensional Gravity, Tensional Background Noise, and Tension-Potential Redshift via the endpoint tensional–pressure difference ΔΠ. Sea coupling k_sSea and recombination k_Recon jointly lift multi-strange yields, while k_Canon<0 captures canonical (small-volume) suppression. The coherence/ damping/response-limit terms stabilize the mid-frequency spectrum by raising f_bend.


II. OBSERVABLES AND UNIFIED CONVENTIONS
• Observables & Definitions
• Strangeness enhancement factor: E_s = [(K+Λ+Ξ+Ω)/π] / [(K+Λ+Ξ+Ω)/π]_{baseline}.
• Ratio spectra: K/π(p_T,N_ch), Λ/K0s(p_T,N_ch), Ξ/π(p_T,N_ch), Ω/π(p_T,N_ch).
• Nuclear/medium modification: R_pA^s(p_T,y); momentum broadening Δ⟨p_T^2⟩ = ⟨p_T^2⟩_A − ⟨p_T^2⟩_p.
• Spectral/coherence: L_coh, S_phi(f), f_bend; significance Z_s.

• Unified Fitting Conventions (three axes + path/measure declaration)
Observable axis: E_s, the four ratio spectra, R_pA^s, Δ⟨p_T^2⟩, L_coh, S_phi(f), f_bend, P(|E_s−E_pred|>τ), Z_s.
Medium axis: Sea / Thread / Density / Tension / Tension Gradient.
Path & measure: propagation path gamma(ell) with measure d ell. All equations appear in backticks; SI units are used.


III. EFT MODELING MECHANISMS (Sxx / Pxx)
• Minimal Equation Set (plain text)
• S01: E_s = E0 · [1 + gamma_Path·J_Path] · [1 + k_sSea·S_sea(μ^2,x)] · [1 + k_Recon·C_R] · [1 + k_STG·G_env + k_TBN·σ_env] · exp(k_Canon·V_eff/V0) · RL(ξ; xi_RL)
• S02: Ratio_i(p_T,N_ch) = h_i(E_s) · F_i(p_T; θ_i) · [1 + beta_TPR·ΔΠ], i∈{K/π, Λ/K0s, Ξ/π, Ω/π}.
• S03: Δ⟨p_T^2⟩ ≈ κ_0 · L_eff · (1 + k_TBN·σ_env), with L_eff = ∫_gamma ρ(ell) d ell.
• S04: S_phi(f) = A/(1+(f/f_bend)^p), with f_bend = f0 · (1 + gamma_Path · J_Path).
• S05: J_Path = ∫_gamma (grad(T) · d ell)/J0; G_env = b1·∇T_norm + b2·∇n_norm + b3·EM_drift + b4·a_vib.
• S06: Canonical suppression: V_eff = V0·[1 + η(N_ch)]; with small volume, k_Canon<0 lowers E_s.
• S07: RL(ξ; xi_RL) is the response-limit factor that suppresses effective gain under strong coupling/high noise.

• Mechanism Highlights (Pxx)
• P01 · Path: J_Path raises f_bend and stabilizes the mid-frequency spectrum, making E_s increase monotonically with path integral.
• P02 · Recon: recombination/covariance (C_R) with sea coupling jointly enhances multi-strange ratios, driving super-linear growth of Ω/π.
• P03 · Statistical Tensional Gravity: G_env aggregates vacuum/thermal/EM/vibrational gradients, increasing Δ⟨p_T^2⟩ and thickening S_phi(f).
• P04 · Tension-Potential Redshift: ΔΠ shifts channel baselines, shaping low-p_T slopes of K/π and Λ/K0s.
• P05 · Tensional Background Noise: σ_env amplifies mid-frequency power-law tails and the variance of strange ratios.
• P06 · Coherence/Damping/Response-Limit: theta_Coh, eta_Damp, and xi_RL govern convergence and robustness under extreme conditions.

VI. OVERALL ASSESSMENT
• Strengths
• A single multiplicative structure (S01–S07) integrates the path term, sea coupling, recombination, canonical suppression, and environmental factors with parameters of clear physical meaning.
• Cross-platform and cross-multiplicity coherence: k_sSea and k_Recon are significantly positive, indicating the dominant role of sea-strangeness and recombination; k_Canon<0 captures small-volume suppression.
• Practicality: a closed-form approximation for E_s(N_ch,p_T,y) and path sensitivity dE_s/dJ_Path facilitates generator reweighting and online quality monitoring.

• Blind Spots
• Extreme high multiplicity or far forward/backward small-x regimes may require non-local kernels and stronger saturation terms.
• Channel-specific constants are first-order approximations and may understate hadronization micro-differences across strangeness classes.

• Falsification Line & Experimental Suggestions
Falsification line: if gamma_Path=k_sSea=k_Recon=k_Canon=k_STG=k_TBN=beta_TPR=theta_Coh=eta_Damp=xi_RL=0 and ΔRMSE < 1%, ΔWAIC < 2 on the same datasets, the associated mechanisms are falsified.
