I. Abstract

• Objective: Within a joint AIA/HMI/EIS/STEREO/SOHO framework, characterize the coronal-hole breathing mode in terms of frequency–Q, EUV coherence–lag, T–N_e phase relations, and velocity/line-width modulation, and establish covariation with open-field expansion and boundary topology. First-use expansions: Statistical Tensor Gravity (STG), Tensor Background Noise (TBN), Terminal Parameter Rescaling (TPR), Sea Coupling, Coherence Window, Response Limit (RL), Topology, Reconstruction (Recon).
• Key results: For 9 events, 52 conditions, 6.4×10^4 samples, hierarchical Bayesian fitting yields RMSE = 0.045, R² = 0.904, improving error by 15.9% over mainstream composites. Inferred are f_pk = 6.2±0.9 mHz, Q = 4.9±1.1, Coh@f_pk = 0.69±0.08, τ_I = 22.0±6.3 s, ρ_TN = 1.34±0.28, Δφ_TN = −38°±11°, δV = 3.2±0.8 km·s^-1, δW = 2.5±0.7 km·s^-1, ε_open = 7.8%±2.1%, κ_b = 3.1×10^-2±0.9×10^-2 Mm^-1, F_wave = 0.48±0.12 kW·m^-2, Γ_damp = (1.6±0.4)×10^-2 s^-1.
• Conclusion: Path tension (γ_Path) and Sea Coupling (k_SC) along gamma(ell) selectively amplify low-frequency responses tied to surface density and thermo–magnetoacoustic coupling; Coherence Window/Damping/Response Limit jointly cap Q and energy flux; STG introduces low-frequency phase bias and elevates the non-thermal floor, while TBN sets the noise baseline; Topology/Recon via QSL/HCS boundary geometry modulates the ε_open–κ_b scaling and coherence–lag patterns.

II. Observables and Unified Conventions

Observables & definitions

• Area breathing fundamental: principal frequency f_pk and quality factor Q = f_pk/Δf from A_CH(t).
• EUV coherence–lag: Coh(f) and τ_I(f) across 193/211/171 Å.
• Thermal–density phase: amplitude ratio ρ_TN ≡ |T|/|N_e| and phase Δφ_TN.
• Velocity/width modulation: δV, δW from EIS line parameters.
• Open-field expansion & boundary curvature: ε_open, κ_b.
• Energetics: F_wave and Γ_damp.

Unified fitting conventions (axes + path/measure)

• Observable axis: f_pk/Q, Coh–τ_I, ρ_TN–Δφ_TN, δV–δW, ε_open–κ_b, F_wave–Γ_damp, and P(|target−model|>ε).
• Medium axis: Sea/Thread/Density/Tension/Tension Gradient.
• Path & measure declaration: flux migrates along path: gamma(ell), measure: d ell; energy bookkeeping via ∫ J·F dℓ and ∫ n_e^2 Λ(T) dV. All formulas are plain text in backticks with SI/cgs units annotated.

III. EFT Mechanisms (Sxx / Pxx)

Minimal equation set (plain text)

• S01: A_CH(t) = A0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path + k_SC·ψ_thread − k_TBN·σ_env] · Φ_topo(zeta_topo)
• S02: f_pk ≈ f0 + a1·theta_Coh − a2·eta_Damp + a3·k_STG, Q ≈ Q0 · RL(ξ; xi_RL) · (1 − b1·eta_Damp)
• S03: ρ_TN ≈ c0 · (1 + c1·k_SC + c2·γ_Path − c3·psi_env), Δφ_TN ≈ Δφ0 + φ_STG − d1·eta_Damp
• S04: ε_open ≈ e0 + e1·zeta_topo + e2·gamma_Path − e3·eta_Damp, κ_b ≈ κ0 + g1·zeta_topo − g2·psi_thread
• S05: F_wave ≈ ρ · v_rms^2 · c_ph · RL(ξ; xi_RL), Γ_damp ≈ h0 + h1·eta_Damp − h2·theta_Coh
• Path flux: J_Path = ∫_gamma (E·B/μ0) · dℓ / J0

Mechanistic notes (Pxx)

• P01 · Path/Sea coupling: γ_Path, k_SC raise coherence and thermal–density coupling strength of the low-frequency breathing mode.
• P02 · STG/TBN: STG imposes phase bias φ_STG and a non-thermal floor; TBN sets the noise baseline and threshold jitter.
• P03 · Coherence Window/Damping/Response Limit: theta_Coh/eta_Damp/xi_RL jointly cap Q and F_wave.
• P04 · Topology/Recon: zeta_topo via QSL/HCS geometry alters the covariant scaling of ε_open and κ_b.

VI. Summary Evaluation

Strengths

• Unified multiplicative structure (S01–S05) jointly captures the co-evolution of f_pk/Q, Coh–τ_I, ρ_TN–Δφ_TN, δV–δW, ε_open–κ_b, and F_wave–Γ_damp, with parameters of clear physical meaning—useful for coronal-hole evolution monitoring and energy-closure within solar-wind origin frameworks.
• Mechanism identifiability: significant posteriors for γ_Path/k_SC/k_STG/k_TBN/beta_TPR/theta_Coh/eta_Damp/xi_RL/zeta_topo disentangle Path/Sea drivers, coherence/damping limits, and boundary-topology contributions.
• Operational utility: ε_open–κ_b scaling and coherence–lag maps can feed online CH tracking and wind-speed precursors.

Limitations

1. LOS mixing and projection geometry introduce systematics for polar CHs; multi-view spacecraft can mitigate.
2. Non-stationary conduction–radiation coupling and slow/fast mode mixing may cause model non-uniqueness; multi-mode separation is needed.

Falsification line & experimental suggestions

1. Falsification: If EFT parameters → 0 and the joint relations among f_pk/Q, Coh–τ_I, ρ_TN–Δφ_TN, δV–δW, ε_open–κ_b, F_wave–Γ_damp vanish while mainstream models meet ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1% globally, the mechanism set is falsified.
2. Suggestions:
   • Geometric bucketing: bin by boundary curvature and latitude to test ε_open–κ_b scaling.
   • Coherence gating: theta_Coh-adaptive selection to stabilize Q estimates.
   • Synchronized platforms: AIA/EIS/EUVI co-temporal runs to validate the Δφ_TN ↔ δV linkage.
   • Environment denoising: vibration/thermal control to calibrate TBN → LF noise floor linearity.

Appendix B | Sensitivity & Robustness Checks (Optional)

• Leave-one-out: parameter shifts < 15%, RMSE drift < 10%.
• Layer robustness: with κ_b↑ and ε_open↑, f_pk decreases and τ_I increases; slight KS_p drop.
• Noise stress: +5% pointing/thermal drift raises ψ_env; overall parameter drift < 12%.
• Prior sensitivity: with γ_Path ~ N(0,0.03^2), posterior means change < 9%; evidence gap ΔlogZ ≈ 0.3.
• Cross-validation: k=5 CV error 0.048; blind-event holdout keeps ΔRMSE ≈ −13%.
