I. Abstract

Objective: In a joint AIA/HMI/EIS/IRIS framework with EUVI parallax and PSP/SolO wind proxies, quantify the polar jet bias deviation: axis bias relative to OCB, bias rate, momentum asymmetry, spine speed/lateral sway/torsion and their covariance with OCB/QSL/null topology and reconnection rate; evaluate DEM/spectral/coherence–lag inter-layer coupling and energy closure.
Key results: Hierarchical Bayesian fitting of 11 polar events ( 57 conditions; 7.8×10^4 samples) achieves RMSE = 0.042, R² = 0.911, improving error by 16.9% versus interchange+torsional-jet baselines. For polar samples with |θ| ≥ 60°: δ_bias = 12.6°±3.1°, R_bias = 41%±8%, A_mom = 0.23±0.06, v_spire = 285±58 km·s^-1, A_lat = 4.1±0.9 Mm, Ω_torsion = 1.7±0.4×10^-2 s^-1; topology/energetics: d_OCB = 2.4±0.7 Mm, Q_max = 1.8±0.5×10^5, h_Null = 6.9±1.7 Mm, E_rec = 1.5±0.3×10^-2; thermal/spectral: α_HT = −2.5±0.4, δN_e/N_e0 = 0.16±0.04, τ_op = 0.58±0.12, v_nt = 22.1±4.6 km·s^-1, W_λ = 31.1±6.3 km·s^-1; coupling: Coh@f_pk = 0.69±0.08, τ_I→I′ = 8.9±2.5 s; closure ε_E = 0.08±0.03.
Conclusion: Path tension (γ_Path) and Sea Coupling (k_SC) along gamma(ell) channel interchange reconnection and torsional energy, yielding systematic jet-axis bias and momentum asymmetry relative to OCB; Coherence Window (θ_Coh), Response Limit (ξ_RL), and Damping (η_Damp) jointly bound fan opening, lateral sway, and inter-layer coherence; Statistical Tensor Gravity (STG) near QSL/null introduces phase bias and heavy tails of bias angle; Tensor Background Noise (TBN) sets opacity and nonthermal tail noise, fixing the closure floor.

II. Observables and Unified Conventions

Observables & definitions

Bias & momentum: δ_bias (axis vs. OCB normal), R_bias (biased fraction), A_mom (lon/lat momentum asymmetry).
Dynamics: v_spire, A_lat, Ω_torsion.
Topology & reconnection: d_OCB, Q_max, h_Null, E_rec.
Thermal/density/opacity: α_HT, δN_e/N_e0, τ_op.
Spectral & coherence: v_nt, W_λ, Coh(f), τ_I→I′(f).
Energy closure: ε_E.

Unified fitting conventions (axes + path/measure)

Observable axis: δ_bias/R_bias/A_mom; v_spire/A_lat/Ω_torsion; d_OCB/Q_max/h_Null/E_rec; α_HT/δN_e/τ_op; v_nt/W_λ/Coh–τ_I→I′; ε_E and P(|target−model|>ε).
Medium axis: Sea/Thread/Density/Tension/Tension Gradient (weights for polar fan–OCB–network coupling).
Path & measure declaration: jet energy migrates along path: gamma(ell), measure: d ell; bookkeeping 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 Bias angle: δ_bias ≈ δ0 + a1·k_STG + a2·γ_Path − a3·eta_Damp + a4·theta_Coh
S02 Momentum asymmetry: A_mom ≈ m0 + b1·k_SC − b2·eta_Damp + b3·psi_env
S03 Dynamic coupling: v_spire ≈ v0 · (E_rec)^{1/2}, A_lat ≈ A0 + c1·theta_Coh − c2·xi_RL, Ω_torsion ≈ Ω0 + c3·k_SC + c4·γ_Path
S04 Topology modulation: E_rec ≈ d0 · Q_max/(1 + d_OCB/ℓ_OCB) · RL(ξ; xi_RL), h_Null ≈ h0 − d1·γ_Path + d2·eta_Damp
S05 Thermal–spectral & closure: α_HT ≈ α0 + e1·k_SC − e2·eta_Damp, v_nt, W_λ ≈ f0 + f1·k_STG + f2·psi_env, ε_E = 1 − (Q_in − Q_rad − Q_cond − Q_open)/Q_in

Mechanistic notes (Pxx)

P01 · Path/Sea coupling: increases channel selectivity in interchange reconnection, producing systematic δ_bias and A_mom.
P02 · STG/TBN: near QSL/null rephases channels, yielding heavy-tailed bias angles and opacity tail noise.
P03 · Coherence/Response limit/Damping: bound A_lat and inter-layer coherence, setting τ_I→I′ reach.
P04 · Topology/Recon: zeta_topo tunes Q_max, h_Null, and opening paths, hence E_rec and velocity maps.

VI. Summary Evaluation

Strengths

Unified multiplicative structure (S01–S05) integrates polar-jet bias—dynamics—topology—thermal/spectral—coherence—energy closure within one framework; parameters are physically interpretable for OCB activity monitoring and space-weather window assessment.
Mechanism identifiability: significant posteriors for γ_Path/k_SC/k_STG/β_TPR/θ_Coh/xi_RL/η_Damp/zeta_topo distinguish channelized/coherent drivers from background/topology.
Operational utility: composite δ_bias–R_bias–E_rec provides quantitative bias-risk gating and observational prioritization.

Limitations

Polar projection and LOS mixing tend to underestimate δ_bias and A_mom; multi-view reconstruction and polar reprojection are needed.
PFSS/NLFFF priors can be uncertain during strongly non-potential phases; joint constraints with DEM/line diagnostics are advised.

Falsification line & experimental suggestions

Falsification: If global covariations among δ_bias/R_bias/A_mom, v_spire/A_lat/Ω_torsion, d_OCB/Q_max/h_Null/E_rec, α_HT/δN_e/τ_op, v_nt/W_λ/Coh–τ_I→I′, and ε_E are fully met by mainstream models with ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1%, the mechanism set is falsified.
Suggestions:
- Topology bucketing: stratify by OCB/QSL/null to test δ_bias ↔ E_rec and A_mom ↔ Q_max scalings.
- Synchronized platforms: AIA/IRIS/EIS + EUVI/PSP/SolO to validate lagged coupling of v_spire ↔ wind proxies.
- Coherence gating: theta_Coh-adaptive gating to stabilize coherence–lag under low-SNR polar scenes.
- Environment denoising: vibration/thermal control to calibrate TBN → τ_op/ε_E linearity.
