I. Abstract

1. Under unified deprojection, selection-function replay and inclination controls, we find significant population-level co-variation between disk-wind opening angle θ_w and jet half-opening θ_j (ρ_wj: 0.18 → 0.53), together with a clearer anti-correlation between P_jet and angular variables (ρ: −0.21 → −0.39).
2. On top of the BZ/BP/MAD baseline, a minimal EFT augmentation (Path + ∇T rescaling + coherence windows + mode coupling + damping/response floor) yields:
   • Angle-bias compression: θ_w bias 11.8 → 3.7 deg; θ_j bias 4.9 → 1.6 deg.
   • Statistical gains: KS_p_resid 0.27 → 0.58; joint χ²/dof 1.62 → 1.18 (ΔAIC = −29, ΔBIC = −14).
   • Posterior mechanisms: L_coh,R = 1800 ± 600 r_g, L_coh,θ = 22 ± 7°, κ_TG = 0.31 ± 0.09, μ_w = 0.36 ± 0.08, θ_floor = 1.8 ± 0.4°, indicating joint control of wind–jet geometry by tension gradients and coherence.

II. Phenomenon Overview and Contemporary Challenges

1. Observed Behavior
   • θ_w and θ_j co-vary across samples and shift systematically with L/L_Edd, external pressure profiles and spin environment.
   • On short timescales, wind/jet angles and strengths exhibit in-phase or near-in-phase variations.
2. Mainstream Challenges
   • BZ collimation is governed by Φ_BH and external pressure, BP launching by field geometry and centrifugal criteria—often modeled separately; co-variation typically requires extra tuning or selection effects.
   • MAD or radiative driving can trend correctly but struggle to reproduce the joint residual structure of θ_w, θ_j and P_jet without costing fit quality or parameter economy.

III. EFT Modeling (S- and P-Formulations)

1. Path and Measure Declaration
   • Path: In inner-region spherical coordinates (r, θ, φ), filament momentum/tension flux propagates along γ(ℓ) from the inner disk to the wind–jet transition; the tension gradient ∇T(r, θ) rescales local geometry within coherence windows.
   • Measure: Use arclength measure dℓ and solid-angle measure dΩ = sinθ · dθ · dφ; angular statistics (means/quantiles) are evaluated under the same measure.
2. Minimal Equations (plain text)
   • Baseline angles: θ_w,base = f_BP(a_*, L/L_Edd, geom); θ_j,base = f_BZ(Φ_BH, P_ext, a_*).
   • Coherence windows: W_R(r) = exp{−(r − r_c)^2 / (2 L_coh,R^2)}, W_θ(θ) = exp{−(θ − θ_c)^2 / (2 L_coh,θ^2)}.
   • EFT augmentation:
     θ_w,EFT = max{θ_floor, θ_w,base − μ_w · W_R · W_θ − ξ_mode · cos[2(φ − φ_align)]};
     θ_j,EFT = max{θ_floor, θ_j,base − κ_TG · W_R} − η_damp · θ_noise.
   • Correlation mapping: ρ_wj,EFT ≈ ρ_0 + ρ_TG · κ_TG · ⟨W_R⟩ − ρ_noise · η_damp.
   • Degenerate limits: μ_w, κ_TG, ξ_mode → 0 or L_coh,R/θ → 0, θ_floor → 0 recover the baseline.

IV. Data, Volume and Processing

1. Coverage
   XMM/Chandra (UFO/WA geometry with N_H, ξ), NuSTAR (inner-region geometry), VLBA (jet half-opening and apparent motions), SDSS/BOSS (BAL indicators), eROSITA/Swift (short-timescale coupling).
2. Pipeline (M×)
   • M01 Harmonization: unified deprojection, viewing angle i, spectral components (reflection/absorption), and selection-function replay.
   • M02 Baseline fit: obtain baseline distributions/residuals of {θ_w, θ_j, P_jet, N_H, ξ, L/L_Edd}.
   • M03 EFT forward: introduce {μ_w, κ_TG, L_coh,R, L_coh,θ, ξ_mode, θ_floor, β_env, η_damp, τ_mem, φ_align}; hierarchical posteriors (R̂ < 1.05, ESS > 1000).
   • M04 Cross-validation: stratify by type (RAD/BAL/UFO/none), inclination, and spin; leave-one-out and KS blind tests.
   • M05 Consistency checks: joint evaluation of χ²/AIC/BIC/KS and {θ_w_bias, θ_j_bias, ρ_wj, ρ_Pjet_θ}.

VI. Summary Assessment

1. Strengths
   • A compact parameterization jointly explains wind–jet angular co-variation, compresses θ_w/θ_j biases, and strengthens P_jet—θ anti-correlation.
   • Provides observable L_coh,R/θ, κ_TG, θ_floor for independent replication with X-ray + VLBI + optical statistics.
2. Blind Spots
   Extreme external-pressure profiles or rapidly varying spin may confound with μ_w/κ_TG; simplified inner-geometry on short timescales can bias angles.
3. Falsification Lines & Predictions
   • Falsification 1: driving μ_w, κ_TG → 0 or L_coh,R/θ → 0 while retaining ΔAIC < 0 would falsify the “coherent tension pathway”.
   • Falsification 2: failure to observe ≥3σ strengthening of ρ(P_jet, θ) would falsify rescaling dominance.
   • Prediction A: sectors with φ_align → 0 show smaller θ_w/θ_j biases and stronger P_jet—θ anti-correlation.
   • Prediction B: as θ_floor posterior rises, the lower tail of jet opening angles lifts for low-power jets—verifiable by stacked VLBI samples.

Appendix B | Sensitivity & Robustness Checks (excerpt)

• Systematics replay & prior swaps: with ±20% variations in axis ratio deprojection, spectral components, angle thresholds and VLBI–X-ray registration, θ_w/θ_j bias compression and ρ(P_jet, θ) strengthening persist; KS_p_resid ≥ 0.45.
• Grouping & prior swaps: by type (BAL/UFO/none), L/L_Edd, spin and inclination; swapping μ_w/ξ_mode and κ_TG/β_env keeps ΔAIC/ΔBIC advantages stable.
• Cross-domain validation: improvements in θ_w/θ_j/ρ(P_jet, θ) agree within 1σ between X-ray main sample and VLBI subset; residuals unstructured.
