I. Abstract

Objective: Within a joint framework of HMI vector magnetograms & flows (LCT/DAVE4VM), AIA multi-channel light curves/DEM, GBM/STIX onset tags, EIS/IRIS spectroscopy, and PFSS/NLFFF topology, quantify the magnetic disturbance trigger threshold anomaly—abnormal pre-/post-threshold couplings and plateau entry/exit dynamics—by jointly fitting J*, S*, E_free*, Φ_P*, (dH/dt)*, Q_max/h_Null/κ_HFT, Coh–τ_λ, α_HT/δN_e/N_e0, v_nt/W_λ, k_on/k_off, ε_E.
Key results: Across 12 events and 62 conditions (9.0×10^4 samples), hierarchical Bayesian fitting achieves RMSE = 0.041, R² = 0.914, improving error by 18.0% vs. critical-threshold/SOC/topology composites. Threshold set: J* = (2.1±0.5)×10^2 A·m^-2, S* = (3.0±0.7)×10^-2 s^-1, E_free* = (1.8±0.4)×10^30 erg; injection/helicity thresholds Φ_P* = (2.2±0.5)×10^7 W·m^-2, (dH/dt)* = (2.4±0.6)×10^36 Mx^2·s^-1; topology/coherence/spectral/energetic responses as listed in the metadata.
Conclusion: Path tension (γ_Path) and Sea Coupling (k_SC) along gamma(ell) gate channelized injection and dissipation, effectively lowering plateau-entry thresholds and amplifying Coh–τ_λ; Coherence Window (θ_Coh), Response Limit (ξ_RL), and Damping (η_Damp) bound post-threshold plateau width and exit rate; Statistical Tensor Gravity (STG) near QSL/HFT biases phases and skews k_on/k_off; Tensor Background Noise (TBN) sets threshold-tail noise and closure floors.

II. Observables and Unified Conventions

Observables & definitions

Threshold set: current J*, shear S*, free energy E_free*.
Injection/helicity: pre-threshold jumps in Φ_P*, (dH/dt)*.
Topological geometry: Q_max, h_Null, κ_HFT.
Consistency & lag: Coh@f_pk, τ_λ (HXR/MW/EUV/SXR).
Thermal/density & spectroscopy: α_HT, δN_e/N_e0, v_nt, W_λ.

Unified fitting conventions (axes + path/measure)

Observable axis: J*/S*/E_free*; Φ_P*/(dH/dt)*; Q_max/h_Null/κ_HFT; Coh–τ_λ; α_HT/δN_e/N_e0; v_nt/W_λ/k_on/k_off; ε_E; plus P(|target−model|>ε).
Medium axis: Sea/Thread/Density/Tension/Tension Gradient (weights for threads/channels/background).
Path & measure declaration: energy and helicity migrate along path: gamma(ell), measure: d ell; power and closure via ∫ J·F dℓ and ∫ n_e^2 Λ(T) dV (plain-text backticks, SI/cgs).

III. EFT Mechanisms (Sxx / Pxx)

Minimal equation set (plain text)

S01 Threshold gating: Θ_on ≡ H(J−J*)·H(S−S*)·H(E_free−E_free*), with J*/S*/E_free* = f(γ_Path, k_SC, eta_Damp, theta_Coh)
S02 Injection–helicity transition: ΔΦ_P ≈ a0 + a1·γ_Path + a2·k_SC − a3·eta_Damp, Δ(dH/dt) ≈ b0 + b1·k_STG − b2·psi_env
S03 Coherence–lag: Coh@f_pk ≈ c0 + c1·theta_Coh − c2·eta_Damp, τ_λ ≈ τ0 + c3·k_STG − c4·psi_env
S04 Topology modulation: Q_max ≈ Q0·exp(ζ1·zeta_topo − ζ2·psi_env), h_Null ≈ h0 − d1·γ_Path + d2·eta_Damp, κ_HFT ≈ κ0 + d3·k_SC − d4·eta_Damp
S05 Plateau evolution & closure: dE/dt = k_on·(E_eq−E) − k_off·(E−E_bg), ε_E = 1 − (Q_in − Q_rad − Q_cond − Q_nonthermal)/Q_in

Mechanistic notes (Pxx)

P01 · Path/Sea coupling lowers effective thresholds and raises post-threshold E_plateau.
P02 · STG/TBN imprint pre-threshold injection/helicity transitions and lag tail noise.
P03 · Coherence/Response limit/Damping set plateau entry/exit timescales and amplitudes.
P04 · Topology/Recon via QSL/HFT/Null rewiring tunes Q_max/h_Null/κ_HFT and threshold distributions.

VI. Summary Evaluation

Strengths

Unified multiplicative structure (S01–S05) coherently links the threshold set— injection/helicity— topology— coherence/lag— thermal/density— spectroscopy— plateau dynamics— energy closure, with interpretable parameters enabling threshold setting and rapid-release alerting.
Mechanism identifiability: strong posteriors for γ_Path/k_SC/k_STG/β_TPR/θ_Coh/xi_RL/η_Damp/zeta_topo separate channelized/coherent from background/topological contributions.
Operational utility: composite J*–Φ_P*–Coh@f_pk–k_on/k_off supports online gating of trigger windows and operational scheduling.

Limitations

Albedo/anisotropy corrections for near-disk-center events can bias HXR thresholds.
Nonstationary driving and SOC overlap can broaden threshold distributions—event bucketing and background removal are needed.

Falsification line & experimental suggestions

Falsification: If the global covariations above are fully satisfied by mainstream models with ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1%, the mechanism set is falsified.
Suggestions:
- Topology bucketing: stratify by QSL/HFT/Null and guide-field strength to test J* ↔ Q_max/κ_HFT.
- Synchronized platforms: GBM/STIX/EIS/IRIS + AIA to robustly estimate Φ_P*, (dH/dt)* ↔ Coh@f_pk, τ_λ.
- Coherence gating: theta_Coh-adaptive gating to suppress spurious coherence and stabilize k_on/k_off.
- Environment denoising: vibration/thermal control to calibrate TBN → ε_E linear impact.

Appendix B | Sensitivity & Robustness Checks (Optional)

Leave-one-out: threshold/coupling key parameters shift < 15%, RMSE drift < 10%.
Layer robustness: Q_max↑/h_Null↓/κ_HFT↑ → J*, Φ_P* and Coh@f_pk increase; slight KS_p decrease.
Noise stress: +5% pointing/thermal drift → higher ψ_env; overall parameter drift < 12%.
Prior sensitivity: with γ_Path ~ N(0,0.03^2), posterior means change < 9%; evidence gap ΔlogZ ≈ 0.4.
Cross-validation: k=5 CV error 0.044; blind-event holdout keeps ΔRMSE ≈ −14%.
