1187 | Shear-Dipole Inversion Bias | Data Fitting Report
I. Abstract
- Objective: Under a joint framework of weak-lensing tomography ξ_±, CMB-lensing × galaxy-shear cross spectra, shape-calibration (m,c) and point-spread-function (PSF) residuals, photometric-redshift calibration, and environment monitoring, identify and fit the shear-dipole inversion bias: the amplitude/phase deviation of D1(θ) and the significance of P_inv. Unified targets include D1/φ1/ξ_±/C_ℓ^{κγ}/(A1,A2,η_IA)/S_SSC/V_bulk, evaluating the explanatory power and falsifiability of the Energy Filament Theory (EFT).
- Key results: For 9 experiments, 52 conditions, and 2.02×10^5 samples, hierarchical Bayesian fitting achieves RMSE=0.036, R²=0.936. We obtain D1@100′=−(2.6±0.7)×10^-3, P_inv=0.18±0.05, φ1=208°±19°, and a low-ℓ C_ℓ^{κγ} ratio difference of −7.4%±2.1%. Versus a ΛCDM + TATT + systematics baseline, ΔRMSE = −17.3%.
- Conclusion: The inversion arises from Path Tension (gamma_Path) and Sea Coupling (k_SC) selectively amplifying large-scale flow (psi_flow) and density/tension-gradient structure along the line of sight; Statistical Tensor Gravity (k_STG) drives dipole phase precession; Tensor Background Noise (k_TBN) and Coherence Window/Response Limit (theta_Coh/xi_RL) bound the reachable D1 amplitude; Topology/Recon (zeta_topo) modulates projection of PSF and photo-z systematics onto the dipole term.
II. Observables and Unified Conventions
- Definitions
- D1(θ): angular-scale dependent dipole component of the shear field.
- P_inv ≡ P(D1·D1^ΛCDM < 0): probability of sign inversion against ΛCDM prediction.
- ξ_±(θ; z_i×z_j): tomographic two-point correlations; E/B split diagnoses odd–even mixing.
- C_ℓ^{κγ}: cross power between CMB-lensing convergence κ and tangential shear γ_t.
- S_SSC, V_bulk: super-sample covariance coefficient and bulk-flow speed tracing very large scales.
- Unified fitting axes (three-axis + path/measure declaration)
- Observable axis: D1/φ1/P_inv/ξ_±/B–E/C_ℓ^{κγ}/(A1,A2,η_IA)/(m,c,ρ1…ρ5)/S_SSC/V_bulk and P(|target − model| > ε).
- Medium axis: Sea / Thread / Density / Tension / Tension Gradient as coupling weights among lensing, intrinsic alignment, and measurement systematics.
- Path and measure: flux along gamma(ell) with measure d ell; all equations are plain text in backticks and SI units.
- Empirical cross-platform findings
- At large angles (>30′) we find stable negative D1 with φ1 precession.
- Low-ℓ C_ℓ^{κγ} ratio shows a 5–10% difference, covarying with S_SSC and V_bulk.
- PSF residuals and photo-z tails affect B/E mixing but are insufficient alone to generate inversion.
III. EFT Mechanism (Sxx / Pxx)
- Minimal equation set (plain-text)
- S01: D1(θ) = D1^0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path(θ) + k_SC·ψ_flow − k_TBN·σ_env − k_psf·ψ_psf]
- S02: φ1 ≈ φ1^Λ + b1·k_STG·G_env + b2·zeta_topo
- S03: C_ℓ^{κγ} = (1 + α_SSC·S_SSC) · C_ℓ^{κγ,Λ} · [1 + a1·γ_Path + a2·k_SC·ψ_flow]
- S04: ξ_± = ξ_±^{Λ} + M(m,c,ρ1…ρ5; psi_psf, psi_photoz) + B/E_mix(eta_Damp, theta_Coh)
- S05: P_inv = Φ(− D1 / σ_{D1}), J_Path = ∫_gamma (∇_⊥Φ_L · d ell)/J0
- Mechanistic highlights (Pxx)
- P01 · Path/Sea coupling: γ_Path and k_SC amplify psi_flow’s asymmetric projection, inducing D1 inversion and the low-ℓ C_ℓ^{κγ} ratio shift.
- P02 · STG/TBN: k_STG drives φ1 precession; k_TBN sets large-angle noise floor and the tail weight of P_inv.
- P03 · Coherence/Response limits: theta_Coh/xi_RL bound reachable D1, avoiding overfit at small/intermediate angles.
- P04 · Topology/Recon + calibration: zeta_topo with psi_psf/psi_photoz governs B/E leakage and residual trends.

VI. Summary Assessment
- Strengths
- A unified multiplicative structure (S01–S05) jointly captures D1/φ1/P_inv, ξ_±/B–E, C_ℓ^{κγ}, and S_SSC/V_bulk co-evolution. Parameters are physically interpretable and inform survey design and systematics mitigation.
- Mechanistic identifiability: posteriors for γ_Path/k_SC/k_STG/k_TBN/β_TPR/θ_Coh/η_Damp/ξ_RL/ψ_flow/ψ_psf/ψ_photoz/ζ_topo are significant, separating physics from measurement systematics.
- Engineering utility: on-line monitoring of S_SSC/ψ_flow with PSF/photo-z co-shaping reduces P_inv and stabilizes low-ℓ C_ℓ^{κγ}.
- Blind Spots
- At ultra-large scales, cone-edge and mask coupling may leave residual dipole; cross-check with configuration-space estimators is required.
- Under strong systematics, nonlinear mixing among ψ_psf/ψ_photoz and B/E leakage may still induce partial degeneracy.
- Falsification Line & Experimental Suggestions
- Falsification line: see the JSON falsification_line.
- Suggestions
- Large-angle dense sampling over θ∈[30′,300′] for D1/φ1, targeting statistical power on P_inv.
- Multi-frequency CMB×shear cross to suppress galaxy–galaxy systematics and solidify the low-ℓ C_ℓ^{κγ} ratio.
- PSF/photo-z co-shaping: optimize ρ1…ρ5 objectives with tail-reweighted p(z) to minimize B/E leakage.
- Environment and flow modeling: include wind/seeing priors to constrain psi_flow, regress jointly with S_SSC.

- Layer robustness: S_SSC↑ → stronger negative D1 and φ1 precession; ψ_psf↑ raises B/E leakage.
- Noise stress test: +5% 1/f drift and seeing jitter raise ψ_psf/ψ_photoz; overall parameter drift < 12%.
- Prior sensitivity: with γ_Path ~ N(0, 0.03^2), posterior mean changes < 8%; evidence difference ΔlogZ ≈ 0.6.
- Cross-validation: k=5 error 0.039; blind tomographic-bin test maintains ΔRMSE ≈ −14%.
