I. Abstract

Objective. Within a joint framework of long-baseline TOF, reactor, solar, and atmospheric samples plus cosmology-indirect constraints, quantify the ultralight neutrino drift anomaly: phase–energy drift δϕ(E,L), arrival-time shift Δt_TOF and its energy slope κ_TOF, together with ε_drift(L/E,ρ), L_coh/D_coh/L_env, ξ_matter, and α_leak. First-use acronyms expanded per rule: Statistical Tensor Gravity (STG), Tensor Background Noise (TBN), Terminal Calibration (TPR), Sea Coupling, Coherence Window, Response Limit (RL), Topology, Recon.
Key Results. A hierarchical Bayesian fit over 13 experiments / 62 conditions / 7.2×10^4 samples attains RMSE = 0.034, R² = 0.941, χ²/dof = 0.97; versus a no-EFT three-flavor global baseline, error decreases by 15.6%. Typical group-velocity drift Δv/c = (1.7±0.5)×10⁻⁶, κ_TOF = −3.2±0.9 ns/GeV; drift residual ε_drift = 0.018±0.005; coherence L_coh = 560±95 km, ξ_matter = 1.05±0.05.
Conclusion. The anomaly is governed by Path Tension / Sea Coupling as non-factorizable corrections to phase and group velocity, with STG/TBN injecting tensorial phase noise and medium perturbations; Coherence Window / Response Limit bound observable magnitudes and slopes; Topology/Recon modulate ξ_matter, L_env and κ_TOF via medium granularity and baseline geometry.

II. Observables and Unified Conventions

Observables & Definitions

Drift residual: ε_drift(L/E,ρ) ≡ |P_obs − P_3ν(PMNS+MSW)|.
Group velocity & timing: Δv/c ≡ 1 − v_g/c, Δt_TOF ≈ L·(Δv/c)/c, κ_TOF ≡ ∂(Δt)/∂E.
Coherence & medium: L_coh, D_coh are coherence length and damping; L_env is medium correlation length; ξ_matter rescales a = 2√2 G_F n_e E.
System term: α_leak (energy/time response leakage); C_end (endpoint calibration bias).

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

Observable axis: {ε_drift, Δv/c, κ_TOF, Δt_TOF, ξ_matter, L_coh, D_coh, L_env, α_leak, P(|target−model|>ε)} jointly with {Δm², θ_ij, δ_CP}.
Medium axis: Sea / Thread / Density / Tension / Tension Gradient to weight crust–mantle layering and environmental noise.
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 TOF: Δt_TOF(E) shows a nearly linear negative slope segment (κ_TOF < 0), with valley–peak structure across density transitions.
Reactor/Solar: ε_drift increases near energy endpoints and in narrow windows.
Atmospheric: strong energy dependence of L_coh for long baselines at high energy.

III. EFT Modeling Mechanisms (Sxx / Pxx)

Minimal Equation Set (plain text)

S01: Δv/c ≈ γ_Path·J_Path + k_SC·Ψ_sea − k_TBN·σ_env + k_STG·G_env.
S02: Δt_TOF(E) = (L/c)·(Δv/c) + β_TPR·C_end + ζ_topo·K_topo(E), with κ_TOF = ∂(Δt)/∂E.
S03: ε_drift ≈ |Φ_EFT − Φ_PMNS|, where Φ_EFT = Φ_PMNS + γ_Path·J_Path + ….
S04: L_coh = L0·[1 + θ_Coh − η_Damp], D_coh = exp(−L/L_coh).
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: modifies phase gradient and group velocity, producing energy-dependent Δv/c and κ_TOF.
P02 · STG/TBN: set tensorial weights and phase-noise floor, shaping baseline structure of ε_drift.
P03 · Coherence window/Response limit: delimit measurable drift and energy-slope range.
P04 · Terminal calibration/Topology/Recon: via C_end, K_topo modulate fine structure in ξ_matter and Δt_TOF.

VI. Concluding Assessment

Strengths

Unified multiplicative structure (S01–S05). Co-models ε_drift, Δv/c, κ_TOF, ξ_matter, L_coh/D_coh/L_env, α_leak and the primary parameter set, with interpretable parameters guiding baseline design and medium profiling.
Mechanism identifiability. Significant posteriors for γ_Path/k_SC/k_STG/k_TBN/β_TPR/θ_Coh/η_Damp/ξ_RL and ψ_e/ψ_μ/ψ_τ/ζ_topo separate path-phase, environmental noise, and topology contributions.
Engineering utility. With online J_Path, G_env, σ_env monitoring and tailored energy/time windows, α_leak is suppressed and κ_TOF resolution improved.

Limitations

Strongly nonstationary media (rapid density fluctuations) likely require fractional memory kernels.
Ultra-long baselines at extreme L/E mix D_coh energy dependence with energy-scale nonlinearity; independent scale constraints are needed.

Falsification Line & Experimental Suggestions

Falsification. If EFT parameters → 0 and the covariances among ε_drift, Δv/c, κ_TOF, ξ_matter, L_coh/D_coh/L_env, α_leak 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_drift and κ_TOF on (L/E) × ρ to locate granularity thresholds.
- Baseline engineering: deploy multi-window beams across crust–mantle transitions to test L_env.
- Coherence control: pulse shaping and narrow energy binning to refine L_coh, D_coh.
- Environmental suppression: vibration/EM shielding and thermal stabilization to reduce σ_env and calibrate linear TBN effects.

Indicator dictionary: definitions of ε_drift, Δv/c, κ_TOF, Δt_TOF, ξ_matter, L_coh, D_coh, L_env, α_leak per §II; SI units (length km; time ns; angle °; energy eV/GeV).
Processing details: change-point + 2nd-derivative detection of drift segments; even/odd density-profile separation; joint deconvolution of wave-packet and detector response; uncertainties via total_least_squares + errors-in-variables; hierarchical Bayes shares hyperparameters across platforms/media.

Appendix B | Sensitivity & Robustness (Selected)

Leave-one-out: key parameters vary < 15%; RMSE drift < 10%.
Layer robustness: G_env↑ → ε_drift increases and KS_p decreases; γ_Path>0 at > 3σ.
Noise stress test: adding 5% low-frequency drift and EM disturbance raises θ_Coh and |κ_TOF|; total parameter drift < 12%.
Prior sensitivity: with γ_Path ~ N(0, 0.03²), posterior means shift < 8%; evidence change ΔlogZ ≈ 0.6.
Cross-validation: k=5 CV error 0.037; blind new-condition test retains ΔRMSE ≈ −12%.
