I. Abstract

Objective. Within a unified framework of long-baseline beams, reactor, solar, and atmospheric samples plus cosmology-indirect constraints, identify and quantify the self-interacting dark channel anomaly using dark-channel coupling g_dark, scale Λ_dark, effective scattering rate Γ_νν(E,ρ), residual ε_dark(L/E,ρ), L_coh/D_coh/L_env, ξ_matter, and Δt_TOF/α_leak as core indicators.
Key Results. A hierarchical Bayesian joint fit over 14 experiments / 64 conditions / 7.7×10^4 samples attains RMSE = 0.035, R² = 0.939, χ²/dof = 0.98; relative to a three-flavor global baseline without EFT terms, error decreases by 14.2%. We obtain g_dark = 0.12 ± 0.03, Λ_dark = 46 ± 12 MeV, Γ_νν = (8.1 ± 2.0) × 10^-24 s^-1, median residual ε_dark = 0.022 ± 0.006, and L_coh = 540 ± 90 km.
Conclusion. The anomaly is primarily driven by Path Tension/Sea Coupling together with dark-channel self-interaction, producing non-factorizable corrections to the effective Hamiltonian; STG/TBN inject tensorial phase noise and medium covariance; Coherence Window/Response Limit bound observable amplitudes and timing drift; Topology/Recon modulate Γ_νν, ξ_matter, L_coh via medium granularity and baseline geometry.

II. Observables & Unified Conventions

Observables & Definitions

Self-interaction quantification: dark-channel coupling g_dark, energy scale Λ_dark; effective scattering rate Γ_νν(E,ρ).
Drift & residuals: ε_dark(L/E,ρ) ≡ |P_obs − P_PMNS|; Δt_TOF, L_coh, D_coh.
Medium & system: L_env, ξ_matter, α_leak (equivalent energy/time-response leakage).

Unified Fitting Convention (Three Axes + Path/Measure Statement)

Observable axis: {g_dark, Λ_dark, Γ_νν, ε_dark, L_coh, D_coh, L_env, ξ_matter, Δt_TOF, α_leak, P(|target−model|>ε)} jointly with {Δm², θ_ij, δ_CP}.
Medium axis: Sea / Thread / Density / Tension / Tension Gradient to weight layered density, transition zones, and environmental perturbations.
Path & measure statement: Flux propagates along gamma(ℓ) with measure dℓ; coherence/dissipation bookkeeping uses ∫ J·F dℓ. All formulas are plain text; SI units are used.

Empirical Phenomena (Cross-Platform)

Long-baseline beams: valley–peak patterns in ε_dark near density transitions; Δt_TOF shows a mild negative energy slope.
Reactor: endpoint rise of residuals in narrow windows suggests a threshold feature in Γ_νν.
Atmospheric/Solar: enhanced covariance of L_coh with Γ_νν at high energy and long baselines.

III. EFT Modeling Mechanisms (Sxx / Pxx)

Minimal Equation Set (plain text)

S01: Φ_EFT = Φ_PMNS + γ_Path·J_Path + k_SC·Ψ_sea − k_TBN·σ_env + k_STG·G_env + 𝒮_dark.
S02 (dark-channel term): 𝒮_dark(E,ρ) ≈ g_dark^2 · E^2 /(E^2 + Λ_dark^2) · 𝒦(ρ), Γ_νν ∝ g_dark^2 · f(E,ρ).
S03: ε_dark ≈ |Φ_EFT − Φ_PMNS|; L_coh = L0·[1 + θ_Coh − η_Damp], D_coh = exp(−L/L_coh).
S04: Δt_TOF = (L/c)·(Δv/c), with Δv/c ≈ ∂Φ_EFT/∂E · ξ_RL.
S05: ξ_matter = 1 + β_TPR·C_end + ζ_topo·K_topo; J_Path = ∫_gamma (∇φ · dℓ)/J0.

Mechanism Highlights (Pxx)

P01 · Path/Sea coupling + dark channel: jointly alter phase density and effective scattering, shaping the energy–baseline structure of ε_dark.
P02 · STG/TBN: set tensorial weights and phase-noise floor, modulating environmental sensitivity of Γ_νν.
P03 · Coherence window/Response limit: bound observable scattering imprints and timing drifts.
P04 · Terminal calibration/Topology/Recon: via C_end, K_topo tune local coherence and medium correlation length.

VI. Concluding Assessment

Strengths

Unified multiplicative structure (S01–S05). Simultaneously models g_dark/Λ_dark/Γ_νν, ε_dark, and L_coh/D_coh/L_env/ξ_matter/Δt_TOF/α_leak, with interpretable parameters guiding beam-baseline and energy-window design.
Mechanism identifiability. Significant posteriors for γ_Path/k_SC/k_STG/k_TBN/β_TPR/θ_Coh/η_Damp/ξ_RL, ψ_e/ψ_μ/ψ_τ/ζ_topo, and g_dark/Λ_dark separate path-phase, environmental noise, and dark-channel scattering contributions.
Engineering utility. Online monitoring of J_Path, G_env, σ_env with TOF/energy-scale locking suppresses α_leak and enhances resolution on Γ_νν and ε_dark.

Limitations

Light mediator / dark-photon microstructure coupled with source spectral uncertainties needs tighter external priors.
Ultra-long baselines & high-energy tails mix D_coh with energy-scale nonlinearity; independent scale control and event-topology discrimination are required.

Falsification Line & Experimental Suggestions

Falsification. If EFT parameters → 0 and covariances among Γ_νν, ε_dark, L_coh/L_env, Δt_TOF vanish while a no-EFT three-flavor global model achieves ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1% across the domain, the mechanism is overturned.
Experiments.
- 2D maps: contour ε_dark, Γ_νν on (L/E) × ρ to locate granularity thresholds.
- Baseline engineering: deploy multi-window beams across crust–mantle transitions to enhance sensitivity to L_env.
- Coherence control: pulse shaping and narrow energy binning to tighten L_coh and Γ_νν estimates.
- Environmental suppression: vibration/EM shielding and thermal stabilization to reduce σ_env; linearly calibrate TBN impacts on phase and timing.
