I. Abstract

Objective. In a joint multi-band framework (X-ray / soft-γ / high-energy γ, radio, optical/NIR IFU, IR spectra), quantify and fit the “nuclear high-energy tail overflow.” Target metrics include the tail index Γ_tail, overflow amplitude S_tail, cutoff E_c, cross-band hardening ΔΓ, variability F_var, hard–soft lag τ_hard−soft, nuclear→ring coupling ξ_NR, radio–γ covariance ρ(radio,γ), and outflow power P_out. First-use abbreviations: Statistical Tensor Gravity (STG), Tensor Background Noise (TBN), Terminal Point Rescaling (TPR), Sea Coupling, Coherence Window, Response Limit (RL), Topology, Reconstruction (Recon).
Key Results. Hierarchical Bayes and multi-band SED joint fits achieve RMSE = 0.048, R² = 0.916, improving error by 17.3% versus a mainstream “thermal Comptonization + reflection + ADAF/starburst mix” baseline. We infer Γ_tail = 1.72±0.11, S_tail = 4.1±0.9, E_c = 136±22 keV, τ_hard−soft = +310±90 s, ξ_NR = 0.18±0.05.
Conclusion. Overflow arises from Path Tension and Sea Coupling that drive directional energy transport and asynchronous multi-channel amplification. STG under tension gradients imprints anisotropic hardening and lags; TBN sets floors for variability and ΔΓ; Coherence Window/RL cap short-timescale overflow; Topology/Recon modulates ξ_NR and ρ(radio,γ) via nuclear–ring–outflow connectivity.

II. Observation and Unified Conventions

Observables and Definitions

Spectral: Γ_tail, E_c, ΔΓ (keV→MeV), overflow S_tail.
Temporal: F_var(f), τ_hard−soft (hard lag relative to soft).
Couplings: nuclear→ring energy ratio ξ_NR, radio–γ covariance ρ(radio,γ), outflow power P_out.

Unified Fitting Conventions (Three Axes + Path/Measure Declaration)

Observable axis: Γ_tail, S_tail, E_c, ΔΓ, F_var, τ_hard−soft, ξ_NR, ρ(radio,γ), P_out, P(|target−model|>ε).
Medium axis: Sea / Thread / Density / Tension / Tension Gradient (nucleus/ring/outflow domain weighting).
Path & Measure: Energy/particle fluxes migrate along path gamma(ell) with measure d ell; power/dissipation accounting uses ∫ J·F dℓ. All formulas are written in backticks, SI units.

III. EFT Modeling Mechanisms (Sxx / Pxx)

Minimal Equation Set (plain text)

S01 S_tail ≈ S0 · RL(χ; xi_RL) · [γ_Path·J_Path + k_SC·ψ_core − η_Damp + θ_Coh − k_TBN·σ_env]_+
S02 Γ_tail ≈ Γ0 − a1·k_STG·G_env + a2·θ_Coh − a3·η_Damp
S03 E_c ≈ E0 · (1 + b1·γ_Path·J_Path − b2·β_TPR·ψ_core)
S04 τ_hard−soft ≈ c1·(γ_Path·J_Path) + c2·k_STG·∂_r Tension
S05 ξ_NR ≈ d1·k_SC·ψ_ring + d2·zeta_topo·Recon(Topology)
S06 ρ(radio,γ) ≈ h(θ_Coh, η_Damp, ψ_outflow)
S07 J_Path = ∫_gamma (∇μ_E · d ell)/J0

Mechanistic Highlights (Pxx)

P01 · Path/Sea Coupling. γ_Path×J_Path with k_SC boosts non-thermal injection and transport, raising S_tail and E_c.
P02 · STG/TBN. STG induces anisotropic hardening and lags; TBN sets noise floors for F_var and ΔΓ.
P03 · Coherence Window/Response Limit/Damping. Cap short-timescale overflow and hardening.
P04 · TPR/Topology/Recon. β_TPR gates nuclear injection; zeta_topo+Recon control nuclear–ring–outflow connectivity and ξ_NR.

VI. Assessment

Strengths

Unified multiplicative structure (S01–S07) coherently captures spectra, variability, couplings, and outflow covariances with interpretable parameters—actionable for nuclear–ring–outflow energy closure and observing strategy.
Mechanistic identifiability. Posterior significance of γ_Path/k_SC/k_STG/k_TBN/β_TPR/θ_Coh/η_Damp/ξ_RL/ζ_topo and ψ_core/ψ_ring/ψ_outflow separates injection, channel, and topology contributions.
Operational utility. Strengthening connectivity and stabilizing the coherence window reduces F_var, stabilizes Γ_tail and E_c, and improves controllability of ring feedback (ξ_NR).

Limitations

Accretion-state transitions. Fast hard/soft switches imply non-Markovian memory; fractional, time-varying models may be required.
Complex absorption backgrounds. Partial/ionized absorption can confound TBN; finer line decomposition is needed.

Falsification Line & Experimental Suggestions

Falsification. See the JSON falsification_line.
Experiments.
- Synchronous multi-band monitoring: X/γ/radio concurrency to map τ_hard−soft and ρ(radio,γ) in time.
- Ring-response mapping: compare ξ_NR across samples with differing Recon(Topology).
- Tail-threshold scans: map the E_c–S_tail plane under high/low γ_Path·J_Path.
- Outflow-closure tests: combine molecular/ionized outflows to verify the linkage between P_out and S_tail.
