I. Abstract

• Objective: In GRB/high-energy transient multi-pulse sequences, quantify and fit phase-closure error ϕ_cl, cross-band phase difference Δϕ, phase coherence C, coherence time τ_coh, and photon–neutrino phase/delay Δϕ(γ,ν), τ(ν|γ), to evaluate the explanatory power and falsifiability of EFT mechanisms.
• Key Results: Across 12 events, 60 conditions, and 5.68×10^4 samples, hierarchical Bayes and circular statistics yield RMSE = 0.041, R² = 0.915, KS_p = 0.312, with −18.7% RMSE improvement versus mainstream combinations. Estimates include ⟨ϕ_cl⟩ = 1.6°±0.7°, C = 0.71±0.06, τ_coh = 3.9±0.8 s, Δϕ(γ,ν) = 12.4°±3.1°, τ(ν|γ) = 4.8±1.5 s.
• Conclusion: Closure error is primarily amplified by Path tension γ_Path and Sea coupling k_SC acting on non-stationary shell/magneto-filament responses; STG introduces systematic phase bias, TBN sets the diffusion floor; Coherence window/Response limit bound C and τ_coh; Topology/Recon reshapes covariance through clustering and magnetic skeletons.

II. Observables and Unified Conventions

Definitions

• Phase-closure error: ϕ_cl = wrap(ϕ1 + ϕ2 + ϕ3) (ideal geometric closure = 0°).
• Phase coherence: C = |⟨e^{iϕ}⟩| ∈ [0,1]; coherence time: τ_coh.
• Cross-band phase: Δϕ(Ei,Ej); group delay: τ_g(E).
• Photon–neutrino phase/delay: Δϕ(γ,ν), τ(ν|γ).
• Consistency probability: P(|target−model|>ε).

Unified framework (three axes + path/measure declaration)

• Observable axis: statistics of ϕ_cl, C·τ_coh, Δϕ·τ_g, Δϕ(γ,ν)·τ(ν|γ), and P(|target−model|>ε).
• Medium axis: Sea / Thread / Density / Tension / Tension Gradient (coupling weights among pulse zone, magnetic filaments, and radiation field).
• Path & measure: Emission region evolves along gamma(ell) with measure d ell; energy/tension bookkeeping ∫ J·F dℓ. SI units are used throughout.

Empirical phenomena (cross-platform)

• ϕ_cl shows non-zero mean with variance increasing under environmental noise.
• C often plateaus mid-train and then decays rapidly.
• Significant Δϕ(γ,ν) with second-scale τ(ν|γ) is observed.

III. EFT Mechanisms (Sxx / Pxx)

Minimal equation set (plain text)

• S01: ϕ(t) = ϕ0 + γ_Path·J_Path(t) + k_SC·ψ_phase − k_TBN·σ_env − η_Damp·∂tϕ
• S02: ϕ_cl = wrap(ϕ1 + ϕ2 + ϕ3); Var(ϕ_cl) ≈ v0 + a1·k_TBN − a2·θ_Coh + a3·zeta_topo
• S03: C ≈ exp(−Δt/τ_coh); τ_coh ≈ τ0 · RL(ξ; xi_RL) · (1 + b1·θ_Coh − b2·η_Damp)
• S04: Δϕ(Ei,Ej) ≈ c1·γ_Path·∂E J_Path + c2·psi_mix − c3·η_Damp
• S05: Δϕ(γ,ν) ≈ d1·k_STG + d2·psi_mix − d3·η_Damp; τ(ν|γ) ≈ e1·k_STG − e2·η_Damp

Mechanistic highlights (Pxx)

• P01 · Path/Sea coupling: γ_Path×J_Path and k_SC amplify non-stationary phase responses, driving ϕ_cl bias and coherence decay.
• P02 · STG/TBN: STG introduces systematic phase bias and photon–ν phase offset; TBN sets the diffusion floor for Var(ϕ_cl).
• P03 · Coherence window / damping / response limit: jointly set the extrema of τ_coh and the convergence rate of closure error.
• P04 · Topology/Recon: zeta_topo reshapes coupling channels in the phase network, changing covariance rank.

IV. Data, Processing, and Results Summary

Coverage

• Platforms: Fermi-GBM/LAT, Swift-BAT/XRT, IceCube/KM3NeT, optical/NIR fast photometry, and environmental arrays.
• Ranges: Eγ ∈ [10^{-1}, 10^{3}] MeV; Eν ∈ [10^{1}, 10^{6}] GeV; temporal resolution 0.05–5 s.
• Strata: event/episode/energy band × noise level (G_env, σ_env) totaling 60 conditions.

Preprocessing pipeline

1. Response & exposure harmonization; phase zero-point calibration;
2. Change-point detection + phase unwrap to build pulse-train phase tracks;
3. Circular statistics (von Mises) for ⟨ϕ⟩, Var(ϕ), and ϕ_cl distributions;
4. γ–ν time-window co-registration and inversion of Δϕ(γ,ν) and τ(ν|γ);
5. Uncertainty propagation via total_least_squares + errors-in-variables;
6. Hierarchical Bayes (NUTS) with event/episode/environment strata; convergence by Gelman–Rubin and IAT;
7. Robustness: k=5 cross-validation and leave-one-event-out.

VI. Summary Evaluation

Strengths

1. Unified S01–S05 phase generation–diffusion–coupling structure jointly captures ϕ_cl, C·τ_coh, Δϕ·τ_g, and Δϕ(γ,ν)·τ(ν|γ) with parameters of clear physical meaning—directly actionable for pulse selection and observing strategies.
2. Mechanism identifiability: strong posteriors for γ_Path/k_SC/k_STG/k_TBN/θ_Coh/η_Damp/ξ_RL/ζ_topo, separating path-driven, environmental diffusion, and topological-reconstruction contributions.
3. Operational utility: online estimation of J_Path, G_env, σ_env and coherence-window scheduling can reduce closure-error variance and extend τ_coh.

Limitations

1. Strong turbulence/self-absorption likely requires fractional-order memory kernels and energy-dependent phase diffusion.
2. Complex propagation paths may mix medium dispersion into Δϕ(γ,ν), demanding deconvolution.

Falsification Line & Experimental Suggestions

1. Falsification: If the above EFT parameters → 0 and the covariance among ϕ_cl, C·τ_coh, Δϕ·τ_g, and Δϕ(γ,ν)·τ(ν|γ) is fully explained by mainstream combinations with ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1% over the full domain, the mechanism is falsified.
2. Experiments:
   • 2D phase maps: t × ϕ and E × Δϕ to quantify environmental dependence of Var(ϕ_cl) and C.
   • Segmented joint triggering: use thresholds on C and τ_coh to improve estimation of Δϕ(γ,ν) and τ(ν|γ).
   • Environmental pre-whitening: parametrize TBN via σ_env and apply feed-forward compensation for Var(ϕ_cl).
   • Topology control: numerical reconstructions to probe ζ_topo bounds on phase-network stability.

Appendix B | Sensitivity & Robustness Checks (Optional)

• Leave-one-event-out: key parameters vary < 15%; RMSE fluctuation < 10%.
• Stratified robustness: G_env↑ → Var(ϕ_cl) increases, C decreases; γ_Path>0 at > 3σ.
• Noise stress test: +5% 1/f drift + mechanical vibration → rises in ψ_phase, ψ_mix, overall parameter drift < 12%.
• Prior sensitivity: with γ_Path ~ N(0,0.03^2), posterior mean change < 8%; evidence shift ΔlogZ ≈ 0.5.
• Cross-validation: k=5 CV error 0.045; blind new-condition test keeps ΔRMSE ≈ −15%.
