I. Abstract


II. Observation Phenomenology & Mainstream Challenges


III. EFT Modeling Mechanism (S & P Conventions)

  1. 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.
  2. 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.
  3. 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

  1. Coverage
    HST/ACS+WFC3, JWST/NIRCam (arc morphology/chromaticity/PSF); KiDS/DES/HSC/LSST (shape catalogs and KS/E/B inversions); ALMA/GMVA/VLA (visibility-domain phase and stripes).
  2. Workflow (M×)
    • M01 Unification: unify PSF and shape m/c; harmonize channelization & uv weighting; same-epoch registration; replay DDE/RIME.
    • M02 Baseline fit: SIE/SPEMD + external shear + isotropic phase screen → residuals in {ω bias, E→B leakage, ρ(γ,ω), curl power, closure phase}.
    • M03 EFT forward: introduce {μ_path, κ_TG, L_coh,θ, L_coh,r, ξ_mode, ψ_rot, p_rot, ω_floor, κ_floor, γ_floor, β_env, η_damp, φ_align}; NUTS/HMC (R̂<1.05, ESS>1000).
    • M04 Cross-validation: buckets by band/azimuth (relative to tangential)/environment; KS blind tests; power-spectrum/secondary-spectrum verification.
    • M05 Consistency: jointly assess χ²/AIC/BIC/KS with {ω bias, E→B leakage, ρ(γ,ω), curl power, closure phase, flexion/PSF residuals}.
  3. Key outputs (examples)
    • Params: ψ_rot=0.14±0.05, p_rot=1.3±0.3, 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, ω_floor=0.010±0.004.
    • Metrics: omega_map_bias=0.006, EB_leakage=0.06, ρ(γ,ω)=0.08, curl_power_bias=0.10, closure_phase_rms=7°, KS_p_resid=0.66, χ²/dof=1.13.

VI. Summative Evaluation

  1. 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.
  2. 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.
  3. 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.
