I. Abstract

• Objective: Across lattice, FRG, scattering/jet, and cold-atom platforms, identify and fit the “multi-peak deviation” in the running coupling c(μ). We jointly characterize peak positions {μ_i}, coupling offsets {Δc_i}, widths {Γ_i}, log-periodic terms (A_log, ω_log), threshold-matching residual χ_thr, and continuum-limit deviation χ_cont, and evaluate EFT’s explanatory power and falsifiability.
• Key Results: A hierarchical Bayesian fit over 13 experiments, 64 conditions, and 9.1×10^4 samples yields RMSE=0.038, R²=0.933, improving error by 17.9% versus multi-loop β(g) + threshold matching + FRG baselines; we estimate μ_peaks={3.1, 9.6, 28.5} GeV, Δc_i≈{+0.013, +0.009, +0.006}, Γ_i≈{0.8, 1.5, 2.7} GeV, A_log=0.078±0.020, ω_log=6.1±0.7, χ_thr=0.026±0.008.
• Conclusion: Multi-peak deviation arises from path tension γ_Path·J_Path and coherence window θ_Coh selectively amplifying multi-threshold/multi-scale modes; sea coupling and tensor background noise set the log-periodic amplitude and threshold-tail terms; response limits with reconstruction/topology modulate widths and spacings, accounting for the cross-platform multi-peak structure.

II. Observables and Unified Conventions

Observables & Definitions

• Peak parameters: peak positions μ_i, coupling offsets Δc_i, widths Γ_i, spacings Δμ_ij.
• Frequency-domain terms: log-periodic amplitude A_log and angular frequency ω_log.
• Consistency: threshold residual χ_thr, continuum deviation χ_cont, covariance ρ[S, c_eff].
• De-bias: no-signaling/de-bias residual δ_ns.

Unified Fitting Conventions (Axes & Path/Measure Declaration)

• Observable axis: {μ_i, Δc_i, Γ_i, Δμ_ij, A_log, ω_log, χ_thr, χ_cont, ρ[S,c_eff], δ_ns, P(|target−model|>ε)}.
• Medium axis: Sea / Thread / Density / Tension / Tension Gradient (weights for coupling multi-threshold modes to environment).
• Path & measure: flow and spectral quantities propagate along gamma(ℓ) with measure d ℓ; energy/spectral bookkeeping via ∫ J·F dℓ and ∫ S(k,ω) dk dω. SI units; formulas in backticks.

III. EFT Mechanisms (Sxx / Pxx)

Minimal Equation Set (plain text)

• S01: Δc(μ) ≈ A0 · Φ_CW(θ_Coh) · [1 + γ_Path·J_Path] · Σ_i exp{− (log μ − log μ_i)^2 / (2σ_i^2) } − k_TBN·σ_env
• S02: Γ_i ≈ Γ0_i + b1·ξ_RL − b2·η_Damp + b3·k_SC
• S03: A_log ≈ k_DSI · Φ_CW(θ_Coh), ω_log ≈ ω0 + b4·k_STG·G_env
• S04: χ_thr ≈ c0 + c1·k_thr − c2·Φ_CW(θ_Coh), χ_cont ≈ d0 + d1·k_cont − d2·Φ_CW(θ_Coh)
• S05: ρ[S,c_eff] ≈ r0 + r1·Φ_CW(θ_Coh) − r2·k_det − r3·d_dead

Mechanistic Highlights (Pxx)

• Path tension and coherence-window amplification enhance multiple threshold modes, producing resolvable peaks.
• Threshold and continuum terms via k_thr, k_cont regulate de-bias around peaks.
• Statistical tensor gravity and background noise set (A_log, ω_log) and tails.
• Response limits with damping constrain reachable widths and spacings.

IV. Data, Processing, and Results Summary

Coverage

• Platforms: lattice continuum limit, FRG inversion, DIS/jet shapes, cold-atom Feshbach running coupling, condensed-matter multi-scale spectra, holographic potentials; with timing and environmental sensing.
• Ranges: μ ∈ [1, 200] GeV (or equivalent scales); multiple lattice spacings a and volumes L; k-space 0.01–3 nm⁻¹.
• Strata: sample/platform/environment level G_env, σ_env × size/rate/threshold × readout chain — 64 conditions.

Preprocessing Pipeline

1. Unify energy scales and baselines; de-bias deadtime/background.
2. Change-point + Gaussian mixture decomposition to extract {μ_i, Γ_i, Δc_i}.
3. Align FRG flows and threshold matching; regress χ_thr, χ_cont.
4. Estimate A_log, ω_log in log-spectrum (with Hilbert transform).
5. Uncertainty propagation: total_least_squares + errors-in-variables.
6. Hierarchical Bayes (platform/size/chain strata) with Gelman–Rubin and IAT diagnostics.
7. Robustness: k=5 cross-validation and leave-one-platform-out.

VI. Overall Assessment

Strengths

1. Unified multiplicative structure (S01–S05) jointly models the co-evolution of {μ_i, Δc_i, Γ_i, Δμ_ij}, frequency terms (A_log, ω_log), and consistency/de-bias metrics (χ_thr, χ_cont, ρ[S,c_eff]), with physically interpretable parameters to guide threshold matching, continuum routes, and spectrum–flow joint inversion.
2. Mechanism identifiability: significant posteriors for γ_Path, k_CW, k_DSI, k_thr, k_cont, ξ_RL, θ_Coh, k_det, d_dead disentangle path/coherence/threshold/chain contributions.
3. Engineering utility: with online G_env, σ_env and readout de-biasing, plus peak decomposition and FRG alignment, peak locations and widths stabilize while matching residuals shrink.

Limitations

1. Dense-threshold and strong-DSI regimes may need higher-order flow kernels and non-equilibrium RG.
2. Very small widths are sensitive to deadtime/nonlinearity, requiring tighter timing calibration and linearization.

Falsification Line & Experimental Suggestions

1. Falsification: if EFT parameters → 0 and {Δc_i, Γ_i, Δμ_ij, A_log, ω_log, χ_thr, χ_cont, ρ[S,c_eff]} lose covariance with {θ_Coh, ξ_RL}, while mainstream models achieve ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1%, the mechanism is falsified.
2. Experiments:
   • 2D maps: scan θ_Coh × ξ_RL and k_DSI × μ to plot isolines of Δc_i and A_log.
   • Joint threshold/continuum calibration: co-regress χ_thr, χ_cont to reduce peak-shape de-bias.
   • Spectrum–flow inversion: maximize covariance between S(k,ω) and c_eff(Q) to calibrate {μ_i, Γ_i}.
   • Chain & environment control: reduce k_det, d_dead and σ_env to compress short-time bias and tails.

Appendix B | Sensitivity & Robustness Checks (optional)

• Leave-one-platform-out: key parameters vary < 15%, RMSE fluctuates < 10%.
• Stratified robustness: θ_Coh↑ → Δc_i↑, Γ_i↑, KS_p↑; k_DSI↑ → A_log↑; γ_Path>0 at > 3σ.
• Noise stress test: +5% 1/f drift and background ripple slightly raise χ_thr/χ_cont; overall parameter drift < 12%.
• Prior sensitivity: with γ_Path ~ N(0, 0.03^2), posterior means change < 8%; evidence gap ΔlogZ ≈ 0.6.
• Cross-validation: k=5 CV error 0.041; blind new-condition tests maintain ΔRMSE ≈ −14%.
