364 | Lens-Plane Shear–Vorticity Decoupling Failure | Data Fitting Report
I. Abstract
- Under a unified convention across HST/JWST high-resolution arcs, KiDS/DES/HSC/LSST shape catalogs, and ALMA/GMVA/VLA visibility-domain data, we fit the lens-plane shear–vorticity decoupling failure. The mainstream “E/B/ω decomposition + isotropic phase-screen correction” cannot, in one framework, simultaneously compress residuals in vorticity-map bias, E→B leakage, γ–ω correlation, ω power-spectrum bias, closure-phase RMS, flexion/PSF residuals, nor explain stripe/vorticity orientations aligned with the tangential direction and cross-frequency scaling.
- Minimal EFT additions—Path (tangential channels), TensionGradient (κ/γ gradient rescaling), CoherenceWindow (angular/radial), ModeCoupling (γ–ω–imaging tri-coupling), and a vorticity channel {ψ_rot, p_rot, ω_floor}—yield a unified recovery of stripe/orientation, alias peak, and E/B/ω leakage without degrading image-position χ² or θ_E.
- Results: strong gains (ω bias: 0.020→0.006, E→B: 0.18→0.06, ρ(γ,ω): 0.25→0.08, curl power bias: 0.30→0.10, closure-phase RMS: 16→7°); global fit quality improves (χ²/dof=1.13, ΔAIC=−33, ΔBIC=−16, KS_p=0.66). Posterior mechanism values—L_coh,θ=0.028±0.008″, L_coh,r=73±24 kpc, κ_TG=0.21±0.06, μ_path=0.29±0.08, ψ_rot=0.14±0.05, p_rot=1.3±0.3, ω_floor=0.010±0.004—support a coherence-window + tension-rescaling + vorticity coupling pathway.
II. Observation Phenomenology & Mainstream Challenges
- Phenomenology
Strong-lens arcs and visibility spectra exhibit quasi-periodic stripes and closure-phase stripes; vorticity ω maps and stripe directions tend to align with the tangential direction of the critical curve, showing near power-law cross-frequency scaling with E→B/ω leakage. - Challenges
Baselines that assume an isotropic screen or treat ω as noise can reproduce m/c and parts of the B-mode but under-explain γ–ω decoupling failure—E→B/ω leakage, orientation alignment, and curl-power normalization. Attributing stripes purely to uv/DDE leaves structured residuals after rigorous replay.
III. EFT Modeling Mechanism (S & P Conventions)
- Path & measure declaration
- Path: in lens-plane polar (r,θ), energy filaments form tangential channels; within L_coh,θ/L_coh,r, they selectively enhance effective deflection and preserve angular κ/γ gradients, driving anisotropic coupling between ISS/systematics and macro geometry.
- Measure: image-plane dA = r dr dθ; morphology uses KS/E/B/ω inversions and power spectra; visibility domain uses baseline length u and closure-phase statistics.
- Minimal equations (plain text)
- Baseline mapping: β = θ − α_base(θ) − Γ(γ_ext, φ_ext)·θ; with μ_t^{-1}=1−κ_base−γ_base, μ_r^{-1}=1−κ_base+γ_base.
- Coherence window: W_coh(r,θ)=exp(−Δθ^2/(2L_coh,θ^2)) · exp(−Δr^2/(2L_coh,r^2)).
- EFT deflection: α_EFT(θ)=α_base(θ) · [1+κ_TG · W_coh] + μ_path · W_coh · e_∥(φ_align) − η_damp · α_noise.
- Vorticity channel: ω_EFT(θ,ν)=ω_floor + ψ_rot · (ν/ν_0)^{−p_rot} · W_coh(r,θ) + ξ_mode · ∂_⊥γ.
- Leakage & correlation: EB_leakage ≈ ⟨∇×α_EFT⟩ / ⟨∇·α_EFT⟩; ρ(γ,ω)=Cov(γ,ω)/(σ_γ σ_ω).
- Degenerate limit: if μ_path, κ_TG, ξ_mode, ψ_rot → 0 or L_coh,θ/L_coh,r → 0 and {ω_floor, κ_floor, γ_floor} → 0, then {ω bias, E→B leakage, ρ(γ,ω)} revert to baseline isotropic-screen expectations.
- Physical interpretation
μ_path enforces selective enhancement and fixes stripe–tangent alignment; κ_TG rescales κ/γ gradients to match curl-power normalization; ψ_rot/p_rot control spectral dependence of vorticity coupling; L_coh,θ/L_coh,r bound geometry–vorticity coupling bandwidth; ω_floor suppresses zero-point bias.
IV. Data Sources, Volume & Processing

VI. Summative Evaluation
- Strengths
A compact coherence-window + tension-rescaling + vorticity channel set systematically reduces residuals in vorticity bias, E→B leakage, γ–ω correlation, ω power bias, and closure-phase RMS across image and visibility domains without sacrificing macro geometry (θ_E). Mechanism parameters {L_coh,θ/L_coh,r, κ_TG, μ_path, ψ_rot, p_rot, ω_floor} are observable and reproducible. - Blind spots
Under extreme LoS fluctuations or strong DDE, residual degeneracy remains between {ψ_rot, φ_align} and instrumental systematics; in strong low-frequency scattering, curl-power estimates may be conservative. - Falsification lines & predictions
- Falsification 1: set μ_path, κ_TG, ψ_rot → 0 or L_coh,θ/L_coh,r → 0; if ρ(γ,ω) and EB_leakage do not decline together (≥3σ), the tangential Path + vorticity-coupling hypothesis is falsified.
- Falsification 2: joint power/secondary-spectrum tests must show curl_power ∝ (ψ_rot)^2 · W_coh; failure (≥3σ) falsifies the vorticity channel.
- Prediction A: decreasing L_coh,θ yields near-linear declines in EB_leakage and closure_phase_rms, with stripes more tightly aligned to tangential.
- Prediction B: high-density environments require larger κ_TG/ψ_rot to achieve the same leakage suppression.

Appendix B | Sensitivity & Robustness Checks (Excerpt)
- Systematics replay & prior swaps
With ±20% variations in uv density, phase noise, DDE residuals, PSF anisotropy, and shape m/c calibration, improvements in {ω bias, E→B leakage, ρ(γ,ω), curl power} persist; KS_p_resid ≥ 0.50. - Grouping & prior swaps
Stable across bands/angle-from-tangential/environment buckets; swapping {ψ_rot, φ_align} with DDE-orientation priors preserves ΔAIC/ΔBIC advantages. - Cross-domain validation
HST/JWST vs KiDS/DES/HSC/LSST, and ALMA/GMVA/VLA subsamples agree within 1σ on {EB leakage, ρ(γ,ω), closure_phase_rms} under common conventions; residuals are unstructured.
