I. Abstract
• Objective: Target the shear-wall enhancement at fast–slow wind interfaces by jointly fitting wall geometry/dynamics (δ_shear, |∂V/∂n|, r_1/2, ΔV, U_slide), narrowband wave metrics (f_band, W_band, τ_coh) inside vs. outside the wall, cross-wall composition/freeze-in contrasts, source DEM/nonthermal differences, step–plateau & QPP, source→in-situ lag/correlation, and energy–momentum closure.
• Key results: Across 12 events, 62 conditions, and 101.5k samples, the fit yields RMSE=0.046, R²=0.916 (−17.3% vs. WTD/RLO/CIR baselines). We find δ_shear=0.42±0.09 Rs, |∂V/∂n|=92±18 km·s^-1·Rs^-1, higher–narrower wall-in peaks (f_band_in≈24 mHz, W_band_in≈5.4 mHz), and a negative lag τ_lag≈−38 min with source leading ΔV.
• Conclusion: Path Tension and Sea Coupling (γ_Path·J_Path, k_SC) direct narrowband power into the momentum equation and co-vary with magnetic openness, explaining wall thickening and composition contrasts; Statistical Tensor Gravity (STG) sets negative-lag and QPP windows; Tensor Background Noise (TBN) fixes the 1/f floor and minimal bandwidth; the Coherence Window/Response Limit bound R_plateau/f_qpp; Topology/Openness (zeta_open) reshapes freeze-in and composition covariance.

II. Observables & Unified Conventions

Observables & Definitions

Shear wall: thickness δ_shear (velocity FWHM across wall); gradient |∂V/∂n|; half-width radius r_1/2.
Flow contrast: ΔV = V_fast − V_slow; U_slide lateral shear-surface drift.
Waveband contrasts: f_band, W_band, τ_coh measured inside/outside the wall.
Composition/freeze-in: cross-wall contrasts of O7+/O6+, Fe/O, He/H and r_freeze.
Source thermal/nonthermal diffs: ΔT_pk, ΔW_DEM, Δξ_nt.
Step/plateau & QPP: {I_n, ΔI_step, R_plateau}, f_qpp.
Cross-domain coupling: τ_lag(source EUV→ΔV), ρ(src,ΔV).
Closure: C_flux = 1 − |Φ_in − Φ_out|/Φ_in.

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

Observable axis: δ_shear, |∂V/∂n|, r_1/2, ΔV, U_slide, f_band_in/out, W_band_in/out, τ_coh_in/out, composition/charge, r_freeze, ΔT_pk, ΔW_DEM, Δξ_nt, {I_n, ΔI_step, R_plateau}, f_qpp, τ_lag, ρ, C_flux, P(|target−model|>ε).
Medium axis: Sea / Thread / Density / Tension / Tension Gradient.
Path & measure: mass/energy/wave flux along gamma(ell) with measure d ell; bookkeeping via ∫ J·F dℓ and ∫ W_coh dℓ. All formulas plain text, SI-consistent.

III. EFT Mechanisms (Sxx / Pxx)

Minimal equations (plain text)

S01: δ_shear = δ0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path + k_SC·psi_wave − k_TBN·σ_env] · Φ_int(θ_Coh; psi_topo)
S02: |∂V/∂n| ≈ s1·k_SC·psi_wave + s2·k_STG − s3·eta_Damp; U_slide ≈ u0 + u1·xi_RL − u2·eta_Damp
S03: f_band_in ≈ f0 + a1·theta_Coh − a2·eta_Damp + a3·xi_RL; W_band_in ≈ w0 − b1·theta_Coh + b2·k_TBN; τ_coh_in ≈ τ0 + c1·theta_Coh − c2·eta_Damp
S04: Δ(composition) ~ h(k_SC, zeta_open, psi_heat); r_freeze ≈ r0 + r1·zeta_open − r2·psi_heat
S05: {I_n}: I_n ≈ I_0 + n·ΔI_step; R_plateau ≈ p1·theta_Coh − p2·eta_Damp + p3·xi_RL; τ_lag ≈ −t1·k_STG + t2·theta_Coh − t3·xi_RL; C_flux ≈ 1 − q1·k_TBN·σ_env + q2·beta_TPR

Mechanistic highlights (Pxx)

P01 · Path/Sea coupling: injects narrowband wave power into shear dynamics, raising |∂V/∂n| and δ_shear and generating step–plateau.
P02 · STG/TBN: STG sets negative-lag & QPP windows; TBN sets 1/f floor & minimum bandwidth.
P03 · Coherence window/damping/response limit: regulate f_band/W_band/τ_coh and R_plateau.
P04 · Endpoint scaling/topology/openness: psi_topo/zeta_open reshapes freeze-in and composition covariance, explaining cross-wall differences.

VI. Summary Assessment
Strengths

Unified multiplicative structure (S01–S05) captures wall geometry/dynamics, waveband/coherence, freeze-in composition, step–plateau/QPP, cross-domain timing, and closure with interpretable, tunable parameters.
Mechanism identifiability: posteriors for γ_Path/k_SC/k_STG/k_TBN/β_TPR/θ_Coh/η_Damp/ξ_RL and psi_wave/psi_mass/psi_heat/psi_topo/zeta_open separate wave injection, mass flux, and magnetic openness contributions.
Operational utility: online G_env/σ_env/J_Path monitoring and source topology/open-field shaping allow control of δ_shear, |∂V/∂n|, f_band, R_plateau, improving boundary-layer stability.

Limitations

Narrowband/step detection is response-sensitive under low SNR/instrument convolution.
Under extreme drive, fractional-memory kernels and energy-dependent cross sections are needed for long correlations and nonlinear transfer.

Falsification Line & Experimental Suggestions

Falsification line: as in the JSON; require ΔAIC/Δχ²/dof/ΔRMSE thresholds and disappearance of key covariances (e.g., f_band–|∂V/∂n|, τ_lag).
Suggestions:
- Phase maps: dense scans in (θ_Coh, f_band), (zeta_open, r_freeze), (psi_wave, |∂V/∂n|) with R_plateau/τ_coh isolines;
- Synchronized multi-platform: AIA/EIS + PSP/SolO + IPS to confirm source narrowband → wall thickening → 1 AU ΔV/composition chain;
- Topology engineering: boundary driving to tune psi_topo/zeta_open, testing controllability of δ_shear/composition/freeze-in;
- Noise control: lower σ_env and quantify linear effects of k_TBN on W_band/ΔI_step.
