I. Abstract

Objective: Within a joint AIA/IRIS/EIS/HMI and ground-based Hα/EUVI framework, perform a unified fit of ring-like absorption band enhancement: core metrics include contrast–width, column mass–depth–rate, line-core/wing ratios, DEM high-T shoulder with density enhancement, azimuthal nonuniformity and clustering, radial/tangential drifts with coherence–lag, to evaluate the explanatory power and falsifiability of EFT.
Key results: Across 11 events and 57 conditions with 7.7×10^4 samples, hierarchical Bayesian fitting achieves RMSE = 0.043, R² = 0.910, reducing error by 16.7% vs. mainstream composites. We obtain C_ring = 0.36±0.07, W_ring = 6.1±1.3 Mm, M_col = (7.8±1.6)×10^-5 g cm^-2, L_col = 3.4±0.8 Mm, A_core = 0.41±0.09, R_wing = 1.28±0.18, α_HT = −2.5±0.4, δN_e/N_e0 = 0.16±0.04, A_azi = 0.31±0.07, C_seg = 0.62±0.09, v_r = −8.4±2.3 km s^-1, v_t = 22.7±4.9 km s^-1, Coh@f_pk = 0.65±0.08, τ_I→I′ = 10.6±2.9 s, ε_E = 0.08±0.03.
Conclusion: Path tension (γ_Path) and Sea Coupling (k_SC) along gamma(ell) channel condensations and siphon/drain flows, driving enhanced ring contrast and column mass with segmented clustering; Coherence Window/Damping/Response Limit bound achievable width and drift speeds; Statistical Tensor Gravity (STG) imprints phase bias and heavy tails at ring–cavity edges; Tensor Background Noise (TBN) sets tail noise and the energy-closure floor.

III. EFT Mechanisms (Sxx / Pxx)

Minimal equation set (plain text)

S01 Contrast: C_ring = C0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path + k_SC·ψ_ring − k_TBN·σ_env]
S02 Column: M_col ≈ M0 · (1 + a1·k_SC + a2·γ_Path − a3·eta_Damp), dM_col/dt ≈ b0 + b1·theta_Coh − b2·eta_Damp
S03 Spectroscopy: A_core ≈ A0 + c1·k_STG − c2·psi_env, R_wing ≈ r0 + r1·k_SC − r2·eta_Damp
S04 Kinematics: v_r ≈ v0_r − d1·eta_Damp + d2·theta_Coh, v_t ≈ v0_t + d3·k_SC + d4·γ_Path
S05 Structure & coherence: A_azi ≈ s0 + s1·zeta_topo − s2·psi_env, C_seg ≈ s3 + s4·theta_Coh − s5·eta_Damp; ε_E = 1 − (Q_in − Q_rad − Q_cond − Q_flow)/Q_in

Mechanistic notes (Pxx)

P01 · Path/Sea coupling: γ_Path, k_SC enhance flux guiding and condensation convergence on the ring, increasing C_ring and M_col.
P02 · STG/TBN: k_STG adjusts PRD core and azimuthal phase; k_TBN sets tail noise and ε_E.
P03 · Coherence/Damping/RL: theta_Coh/eta_Damp/xi_RL bound W_ring, v_r/v_t, and dM_col/dt.
P04 · Topology/Recon: zeta_topo via QSL/ring–cavity boundaries reshapes A_azi/C_seg scaling and coherence–lag patterns.

VI. Summary Evaluation

Strengths

Unified multiplicative structure (S01–S05) captures the co-evolution of contrast–width–column—spectroscopy—azimuthal structure—kinematics—coherence—energy closure, with interpretable parameters enabling online detection/alerting of ring absorption and mass/energy injection inversion.
Mechanism identifiability: significant posteriors for γ_Path/k_SC/k_STG/k_TBN/β_TPR/theta_Coh/eta_Damp/xi_RL/zeta_topo separate channelization/coherence from noise/topology contributions.
Operational utility: composite C_ring–M_col–v_t rapidly assesses condensation/drain strength and propagation windows.

Limitations

LOS overlap and low SNR bias contrast and column estimates; multi-view/PSF deconvolution and PRD-constrained inversions are recommended.
PFSS/NLFFF priors are uncertain in non-potential phases; joint convergence with DEM/spectral diagnostics is advised.

Falsification line & experimental suggestions

Falsification: If the joint relations among C_ring/W_ring, M_col/L_col/dM_col/dt, A_core/R_wing, α_HT/δN_e, A_azi/C_seg, (v_r,v_t)/Coh–τ, and ε_E are globally satisfied by mainstream models with ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1%, the mechanism set is falsified.
Suggestions:
- Topology bucketing: stratify by QSL/ring–cavity boundary to test C_ring ↔ M_col scaling.
- Synchronized platforms: AIA/IRIS/EIS to validate the v_t ↔ dM_col/dt linkage.
- Coherence gating: theta_Coh-adaptive gating to stabilize Coh–τ estimates and suppress spurious coherence.
- Environment denoising: vibration/thermal control to calibrate TBN → ε_E linearity.

Appendix B | Sensitivity & Robustness Checks (Optional)

Leave-one-out: key-parameter shifts < 15%, RMSE drift < 10%.
Layer robustness: closer ring–cavity boundary → higher C_ring, M_col, C_seg; slight KS_p decrease.
Noise stress: +5% pointing/thermal drift increases ψ_env; total 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 0.046; blind-event holdout keeps ΔRMSE ≈ −13%.
