I. Abstract
• Objective: Within a multi-zone framework of coronal flux rope–reconnection–radiation, jointly fit filament twist T_w, helicity H_rel/dH/dt, twist-release enhancement G_tw, reconnection rate E_rec and ribbon drift V_ribbon, nonthermal broadening ξ_nt and electron temperature T_e, flare/CME metrics F_SXR/Δt/V_CME, multi-channel step/plateau {I_n, ΔI_step, R_plateau}, and EUV↔X lag/correlation τ_lag/ρ to assess EFT’s explanatory power and falsifiability.
• Key results: Across 12 events, 65 conditions, and 1.07×10^5 samples, hierarchical Bayesian fitting attains RMSE=0.045, R²=0.917, a −17.5% error reduction vs. baselines; we find G_tw≈2.1, E_rec≈6.7 V·m^-1, V_CME≈1040 km·s^-1, and a negative lag τ_lag≈−13.8 ms (171Å→X) with a stable plateau–step morphology.
• Conclusion: Path Tension and Sea Coupling (γ_Path·J_Path, k_SC) asymmetrically weight the seed–reconnection–radiation channels, triggering rapid twist release and energy transfer; Statistical Tensor Gravity (STG) sets negative-lag and anisotropy windows; Tensor Background Noise (TBN) fixes the 1/f floor and plateau jitter; the Coherence Window/Response Limit constrain widths and R_plateau; Topology/Reconstruction (zeta_topo) re-arranges magnetic connectivity, linking E_rec–V_ribbon–V_CME covariance.

II. Observables & Unified Conventions

Observables & Definitions

Twist & helicity: T_w = (1/2π)∮ τ_g ds; H_rel = ∫_V (A·B − A_p·B_p) dV, with dH/dt from flux-injection.
Twist-release enhancement: G_tw = (dT_w/dt)_eruption / (dT_w/dt)_pre.
Reconnection rate: E_rec ≈ V_ribbon · B_n; V_ribbon from ribbon drift speed.
Spectroscopic temperature & broadening: ξ_nt (nonthermal velocity width), T_e (multi-ion fit).
Flare/CME: F_SXR (GOES class), Δt, V_CME (LASCO).
Steps/plateaus: {I_n, ΔI_step, R_plateau} via change-point + 2nd-derivative detection.
Lag & correlation: τ_lag(λ) = argmax_τ CCF_{EUV(λ), X}(τ); ρ(EUV,X) normalized correlation.

Unified fitting axes (three-axis + path/measure declaration)

Observable axis: T_w, H_rel, dH/dt, G_tw, E_rec, V_ribbon, ξ_nt, T_e, F_SXR, Δt, V_CME, {I_n, ΔI_step, R_plateau}, τ_lag, ρ, P(|target−model|>ε).
Medium axis: Sea / Thread / Density / Tension / Tension Gradient.
Path & measure: energy/particle flux along gamma(ell) with measure d ell; reconnection/radiation bookkeeping via ∫ J·F dℓ and ∫ W_coh dℓ. All formulas are plain-text, SI-consistent.

III. EFT Mechanisms (Sxx / Pxx)

Minimal equations (plain text)

S01: G_tw ≈ g0 · [1 + γ_Path·J_Path + k_SC·psi_seed − k_TBN·σ_env] · Φ_int(θ_Coh; psi_interface)
S02: E_rec ≈ e0 · (k_STG·G_env + psi_recon) · (1 + ξ_RL − eta_Damp)
S03: {I_n}: I_n ≈ I_0 + n·ΔI_step; R_plateau ≈ r1·theta_Coh − r2·eta_Damp + r3·xi_RL
S04: τ_lag(λ) ≈ −t1·k_STG + t2·theta_Coh − t3·xi_RL; ρ(EUV,X) ≈ ρ0·(1 − q1·k_TBN)
S05: V_CME ≈ v0 · (E_rec)^α · (H_rel)^β; J_Path = ∫_gamma (∇μ · d ell)/J0

Mechanistic highlights (Pxx)

P01 · Path/Sea coupling: γ_Path×J_Path and k_SC amplify twist release and lower reconnection thresholds.
P02 · STG/TBN: STG fixes negative-lag and energy-transfer direction; TBN sets step jitter and 1/f background.
P03 · Coherence window/damping/response limit: control plateau fraction and radiative width; bound extreme acceleration.
P04 · Endpoint scaling/topology/reconstruction: psi_interface/ζ_topo reorganize magnetic connectivity, modulating E_rec–V_CME–R_plateau covariance.

VI. Summary Assessment
Strengths

Unified multiplicative structure (S01–S05) jointly captures T_w/H_rel/dHdt/G_tw, E_rec/V_ribbon, ξ_nt/T_e, F_SXR/Δt/V_CME, {I_n, ΔI_step, R_plateau}, and τ_lag/ρ, with physically interpretable, controllable parameters.
Mechanism identifiability: significant posteriors for γ_Path/k_SC/k_STG/k_TBN/β_TPR/θ_Coh/η_Damp/ξ_RL and psi_seed/psi_recon/psi_interface/psi_corona/ζ_topo separate path coupling, reconnection triggering, and topological reconfiguration.
Operational utility: online G_env/σ_env/J_Path monitoring and magnetic topology shaping can boost E_rec, stabilize step-plateaus, and optimize CME speed control.

Limitations

In strong absorption/scattering geometries, plateaus may mix with edge features.
Under extreme drive, fractional-memory kernels and energy-dependent cross sections are needed to describe long correlations and nonlinear acceleration.

Falsification Line & Experimental Suggestions

Falsification line: as in the JSON falsification_line; require global ΔAIC/Δχ²/dof/ΔRMSE thresholds and disappearance of key covariances.
Suggestions:
- Phase maps: dense scans in (dH/dt, G_tw) and (E_rec, V_CME) with R_plateau/τ_lag isolines;
- Synchronized multi-platform: AIA/HMI/EIS/IRIS/GOES/LASCO to verify the hard link among negative lag – reconnection – CME;
- Topology engineering: adjust ζ_topo/psi_interface via flux-rope injection/tether-cutting geometry to test controllability of E_rec–R_plateau;
- Noise control: reduce σ_env, quantify linear effects of k_TBN on step jitter and ρ(EUV,X).
