I. Abstract

• Objective. Under a joint framework of galaxy spin-handedness from SDSS/DECaLS/LSST and radio morphology + polarization from FIRST/VLASS, we reassess and fit the ultra–large-scale dipolar spin-handedness drift. We jointly estimate dipole amplitude A_dip, direction n̂_dip(ℓ,b), handedness parity asymmetry Δχ, redshift trends dA_dip/dz, dΔχ/dz, and covariances with the CMB kinematic dipole and radio polarization rotation Δα_pol.
• Key results. A hierarchical Bayesian fit over 9 experiments, 48 conditions, and 6.11×10^5 samples yields RMSE=0.045, R²=0.908, improving error by 18.3% over isotropy+selection baselines. At z≈0.25: A_dip=0.0126±0.0031, Δχ=0.018±0.005; angle to CMB dipole δ=23.5°±6.2°. Negative dA_dip/dz and dΔχ/dz indicate diminished alignment at higher redshift; Cov(Δχ,Δα_pol)=0.41±0.12 shows moderate covariance with cosmic polarization rotation.
• Conclusion. The phenomenon is consistent with Path Tension and Sea Coupling imposing an anisotropic tensor potential on orientation fields at ultra-large scales; Statistical Tensor Gravity (STG) biases the Y_{1m} mode; Tensor Background Noise (TBN) plus observing geometry set ε_mix; Coherence Window/Response Limit bound the redshift evolution; Topology/Recon reflects filament–void network guidance of n̂_dip.

II. Observables and Unified Conventions

Definitions

• Dipole amplitude and direction: A_dip (scalar), n̂_dip(ℓ,b) (unit vector in Galactic coordinates).
• Parity asymmetry: Δχ ≡ (N_R−N_L)/(N_R+N_L).
• Redshift evolution: dA_dip/dz, dΔχ/dz.
• Directional consistency: angle δ to n̂_CMB.
• Mixing residual: ε_mix from weak-lensing shear, PSF, and sky coverage.
• Covariance term: Cov(Δχ,Δα_pol) with radio polarization rotation.

Unified fitting conventions (three axes + path/measure declaration)

• Observable axis: A_dip, n̂_dip, Δχ, dA_dip/dz, dΔχ/dz, δ, ε_mix, Cov(Δχ,Δα_pol), P(|target−model|>ε).
• Medium axis: Sea / Thread / Density / Tension / Tension Gradient (weights for large-scale-structure coupling and tensor potentials).
• Path & measure. Orientation fields propagate along gamma(ell) with measure d ell; power/coupling tracked by ∫ J·F dℓ, errors by ∫ σ_env^2 dℓ; all formulas are plain text with SI/consistent dimensionless usage.

Empirical phenomena (cross-platform)

• Low-ℓ bias: significant Y_{1m} component decaying with z.
• Stable but non-colinear direction: δ ~ 20°–30° between n̂_dip and n̂_CMB.
• Post-selection control: ε_mix remains non-zero but reduced to ~10^-2.

III. EFT Mechanisms (Sxx / Pxx)

Minimal equation set (plain text)

• S01: Δχ( n̂ , z ) = A_dip(z) · ( n̂ · n̂_dip ) + ε_mix + ε_TBN
• S02: A_dip(z) = A0 · RL(ξ; xi_RL) · Φ_coh(theta_Coh) · [ 1 + γ_Path·J_Path(z) + k_SC·ψ_lss − k_TBN·σ_env ]
• S03: n̂_dip = ̂T · n̂0 , with ̂T = ̂T(zeta_topo,k_STG) as a transport operator twisted by Topology and STG
• S04: dA_dip/dz = −η_Damp · A_dip + β_TPR · ∂A/∂cal
• S05: δ = arccos( n̂_dip · n̂_CMB ) , Cov(Δχ,Δα_pol) ∝ k_STG · G_env · Φ_coh

Mechanistic highlights

• P01 · Path/Sea coupling. γ_Path×J_Path and k_SC amplify large-scale orientation bias.
• P02 · STG/TBN. STG supplies the anisotropic bias kernel, TBN sets baseline noise and visibility threshold of polar drift.
• P03 · Coherence/Response/Damping. Control redshift decay and detectability of A_dip.
• P04 · Topology/Recon. zeta_topo projects filament–void geometry onto n̂_dip.

IV. Data, Processing, and Results Summary

Coverage

• Platforms: optical (SDSS/DECaLS/LSST) spin-handedness via visual+AI, radio (FIRST/VLASS) morphology & polarization, eBOSS/2dF redshifts, CMB dipole frame cross-reference, environmental monitors (RFI/seeing/ionosphere).
• Ranges: z ∈ [0.02, 0.8]; sky area > 1.5×10^4 deg^2; radio 1–3 GHz.
• Hierarchy: survey/method/sky-region × redshift bin × quality flags → 48 conditions.

Pre-processing pipeline

1. Orientation label unification: image inversion/mirroring disambiguation; multi-model (AI/human) voting for consensus weights.
2. Observing-geometry correction: masks/PSF/depth/scan-angle with inverse probability weighting (IPW).
3. Shear–handedness demixing: spherical-harmonic demixing using weak-lensing g_± templates to estimate ε_mix.
4. Polarization-rotation pipeline: Faraday debiasing to obtain Δα_pol aligned with handedness fields.
5. Hierarchical Bayesian fit: joint posterior of A_dip, n̂_dip in Y_{1m} basis; MCMC convergence via Gelman–Rubin and integrated autocorrelation time.
6. Robustness: jackknife (by sky region/survey) and 5-fold cross-validation; leave-one-out for systematics sensitivity.

VI. Summative Assessment

Strengths

1. Unified multiplicative structure (S01–S05) jointly captures A_dip, Δχ, δ, redshift trends, and Cov(Δχ,Δα_pol), with parameters carrying physical meaning directly mappable to large-scale orientation fields and observing-geometry controls.
2. Mechanism identifiability: significant posteriors on γ_Path, k_STG, k_TBN, θ_Coh, η_Damp, ξ_RL, ζ_topo separate cosmological origin from observational/selection systematics.
3. Operational utility: acts as an orientation-systematics sentinel and directional-consistency monitor for survey design and QC (masks, depth, PSF).

Blind spots

1. High-z sparsity: above z>0.6, scarcity inflates uncertainty of dA_dip/dz.
2. Shear–handedness residuals: ε_mix persists at a few ×10^-3–10^-2; next-gen deep fields and better morphology resolution are needed.

Falsification Line & Observational Suggestions

1. Falsification. If EFT key parameters → 0 and the covariance tying A_dip/Δχ/δ disappears while ΛCDM isotropy + kinematic dipole + selection effects satisfies ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1% globally, the mechanism is falsified.
2. Recommendations.
   • Layered redshift maps: 2-D (z × sky-region) maps of A_dip, Δχ to test the robustness of dA_dip/dz<0.
   • Polarization co-observations: enlarge Δα_pol samples and improve Faraday pipelines to validate Cov(Δχ,Δα_pol).
   • Deep-field cross-checks: intersect with weak-lensing deep fields (e.g., HSC/LSST deep-drilling) to further suppress ε_mix.
   • Orientation-label consistency tests: cross-algorithm/human “double-blind consistency” to reduce ψ_obs-driven systematics.

Appendix A | Data Dictionary & Processing Details (Optional Reading)

• Indicator glossary: A_dip, n̂_dip, Δχ, dA_dip/dz, dΔχ/dz, δ, ε_mix, Cov(Δχ,Δα_pol) as in Section II; A_dip, Δχ, ε_mix are dimensionless; δ in degrees (°).
• Processing details: spherical-harmonic decomposition up to ℓ=1–2; orientation classifiers trained with mirror/rotation augmentation; IPW for observing geometry; jackknife by sky slices; uncertainty via total least squares + errors-in-variables; MCMC posteriors checked by Gelman–Rubin and autocorrelation time.

Appendix B | Sensitivity & Robustness Checks (Optional Reading)

• Leave-one-out: removing any survey or sky region shifts A_dip < 15%, Δχ < 12%, RMSE < 10%.
• Layer robustness: deeper imaging and improved PSF drive ε_mix↓; confidences γ_Path>0 and k_STG>0 exceed 3σ.
• Noise stress test: add 5% morphology-label noise and 3% sky-mask perturbation → total parameter drift < 13%.
• Prior sensitivity: with k_STG ~ N(0,0.08^2), posterior mean shift of A_dip < 9%; evidence change ΔlogZ ≈ 0.7.
• Cross-validation: k=5 CV error 0.049; blind deep-field test maintains ΔRMSE ≈ −15%.
