I. Abstract

Objective: In a joint AIA/EIS/IRIS/HMI/EUVI/GOES framework, identify and fit two-temperature plasma retention in terms of emission partition, dwell times, and conduction suppression, quantifying EM_hot/EM_cool, τ_hot/τ_cool/Δt_hot→cool, f_cond, α_hot/α_cool, R_ret, and energy closure ε_E. 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: Hierarchical Bayesian fitting over 11 events, 60 conditions, 8.2×10^4 samples achieves RMSE = 0.044, R² = 0.907, improving error by 17.0% over mainstream two-temperature energetics. We infer ρ_EM = 0.44±0.09, τ_hot = 34.7±6.9 min, τ_cool = 58.2±9.7 min, Δt_hot→cool = 17.3±4.1 min, f_cond = 0.36±0.08, R_ret = 1.41±0.18, ε_E = 0.08±0.03, and DEM shoulders α_hot = −2.6±0.4, α_cool = −1.3±0.3.
Conclusion: Path tension (γ_Path) and Sea Coupling (k_SC) along gamma(ell) selectively elevate hot-channel retention and energy injection; Coherence Window/Damping/Response Limit cap τ_hot/τ_cool and DEM shoulder slopes; STG introduces phase asymmetry and a non-thermal floor, TBN sets threshold jitter and energy-closure residuals; Topology/Recon via QSL/HFT and mirror networks modulates f_cond and R_ret scalings.

II. Observables and Unified Conventions

Observables & definitions

Emissions & ratio: EM_hot (T>6 MK), EM_cool (≈1–2 MK), ρ_EM = EM_hot/EM_cool.
Retention & lag: τ_hot, τ_cool (e-folding), Δt_hot→cool.
Conduction & mirror: f_cond = κ_eff/κ_Spitzer, M_mirror.
Energy closure: Q_in, Q_rad, Q_cond, residual ε_E.
Non-thermal indicators: v_nt, W_λ, amplitudes δv_nt/δW_λ.
DEM slopes: α_hot, α_cool.
Retention index: R_ret = τ_hot/(τ_hot^{MS}) (extension factor vs. mainstream baseline).

Unified fitting conventions (axes + path/measure)

Observable axis: EM_hot/EM_cool/ρ_EM, τ_hot/τ_cool/Δt, f_cond/M_mirror, α_hot/α_cool, R_ret/ε_E/δv_nt/δW_λ, 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.

III. EFT Mechanisms (Sxx / Pxx)

Minimal equation set (plain text)

S01: τ_hot = τ0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path + k_SC·ψ_thread − k_TBN·σ_env] · Φ_topo(zeta_topo)
S02: f_cond = f0 · (1 − a1·eta_Damp + a2·theta_Coh − a3·ψ_env), R_ret ≈ (τ_hot / τ_hot^{MS})
S03: ρ_EM ≈ b0 · (1 + b1·k_SC + b2·γ_Path − b3·eta_Damp)
S04: Δt_hot→cool ≈ c0 + c1·theta_Coh − c2·eta_Damp + c3·k_STG
S05: ε_E = 1 − (Q_in − Q_rad − Q_cond)/Q_in, α_{hot/cool} = α0 ± d1·k_SC ± d2·γ_Path − d3·eta_Damp
Path flux: J_Path = ∫_gamma (E·B/μ0) · dℓ / J0

Mechanistic notes (Pxx)

P01 · Path/Sea coupling: γ_Path, k_SC boost hot-channel injection and extend τ_hot, raising ρ_EM.
P02 · STG/TBN: STG sets phase bias and lag; TBN governs threshold jitter and ε_E.
P03 · Coherence/Damping/Response-Limit: theta_Coh/eta_Damp/xi_RL set ceilings for f_cond and τ.
P04 · Topology/Recon: zeta_topo via QSL/HFT/mirror networks shifts M_mirror and hot–cool coupling efficiency.

VI. Summary Evaluation

Strengths

Unified multiplicative structure (S01–S05) jointly captures the co-evolution of EM_hot/EM_cool/ρ_EM, τ_hot/τ_cool/Δt, f_cond/M_mirror, α_hot/α_cool, R_ret/ε_E/δv_nt/δW_λ, with parameters of clear physical meaning—directly useful for trapping/retention diagnostics and energy-budget closure.
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 coupling, coherence/damping, and topology/environment contributions.
Operational utility: online estimates of R_ret and f_cond feed precursor alerts and heating strategy assessment (observing ops).

Limitations

Nonlocal conduction and turbulent-closure non-uniqueness may bias f_cond; multi-modal constraints help.
LOS mixing and projection geometry in complex arcades introduce systematics; multi-view cross-checks recommended.

Falsification line & experimental suggestions

Falsification: If the joint relations among ρ_EM, τ_hot/τ_cool/Δt, f_cond/M_mirror, α_hot/α_cool, R_ret, ε_E vanish while mainstream models meet ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1% globally, the mechanism set is falsified.
Suggestions:
- Mirror & length bucketing: test R_ret ↔ (M_mirror, L) scaling.
- Synchronized spectroscopy–imaging: AIA + EIS + IRIS co-temporal runs to tighten f_cond estimates.
- Coherence gating: theta_Coh-adaptive selection for stable τ retrievals.
- Environment denoising: vibration/thermal control to calibrate TBN → ε_E linear dependence.

Dictionary: EM_hot/EM_cool/ρ_EM (cm^-5), τ_hot/τ_cool/Δt (min), f_cond (unitless), M_mirror (unitless), α_hot/α_cool (unitless), R_ret (unitless), ε_E (unitless), δv_nt/δW_λ (km·s^-1).
Details: DEM posterior sampling propagation; state-space–Kalman retention fits; energy ledger Q_in = Q_rad + Q_cond + dU/dt; uncertainty via total_least_squares and errors-in-variables; hierarchical MCMC with layer-wise posteriors.

Appendix B | Sensitivity & Robustness Checks (Optional)

Leave-one-out: parameter shifts < 15%, RMSE drift < 10%.
Layer robustness: with M_mirror↑ and L↓, R_ret increases and f_cond decreases; 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 ≈ 0.4.
Cross-validation: k=5 CV error 0.047; blind-event holdout keeps ΔRMSE ≈ −14%.
