I. Abstract

Objective. On void-canopy ring-like structures, detect and fit twisted phase bands—continuous tangential phase offsets around the canopy—manifesting as weak-lensing E/B phase shifts, BAO phase micro-tuning, and covariance with CMB lensing κ. Jointly estimate A_tw, Δφ_band, ω_tw, Δϕ_E/Δϕ_B/Δϕ_EB, Δϕ_BAO, C_ℓ^{void–κ} and A_GI, ε_mix.
Key results. A hierarchical Bayesian fit across 8 experiments, 52 conditions, and 7.24×10^5 samples yields RMSE=0.043, R²=0.914, improving error by 17.9% over Gaussian-phase + standard shear baselines. We obtain A_tw=0.023±0.006, Δφ_band=28.4°±7.1°, ω_tw=4.6°±1.3°/rad, Δϕ_EB=4.1°±1.4°, Δϕ_BAO=3.3°±1.1°, and C_ℓ^{void–κ}=(2.8±0.6)×10^-3.
Conclusion. Twisted phase bands are consistent with Path Tension + Sea Coupling imposing an anisotropic tensor potential over void canopies; Statistical Tensor Gravity (STG) biases low-ℓ phases; Tensor Background Noise (TBN) sets visibility thresholds; Coherence Window/Response Limit bound redshift evolution and bandwidth; Topology/Recon transfers filament–void geometry into band orientation and twist rate.

II. Observables and Unified Conventions

Definitions

Band amplitude & width: A_tw (dimensionless), Δφ_band (°).
Twist rate: ω_tw ≡ dφ/dθ, the azimuthal phase rotation rate along the canopy.
E/B phase offsets: Δϕ_E, Δϕ_B, with difference Δϕ_EB ≡ Δϕ_E − Δϕ_B.
BAO phase offset: Δϕ_BAO and trend dΔϕ_BAO/dz.
Cross-modal covariance: C_ℓ^{void–κ} and A_GI.
Systematics residual: ε_mix after shear/PSF/geometry demixing.

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

Observable axis: A_tw, Δφ_band, ω_tw, Δϕ_E/Δϕ_B/Δϕ_EB, Δϕ_BAO, C_ℓ^{void–κ}, A_GI, ε_mix, P(|target−model|>ε).
Medium axis: Sea / Thread / Density / Tension / Tension Gradient (weights for canopy–filament tensor-potential coupling).
Path & measure. Orientation/phase propagates along gamma(ell) with measure d ell; coupling/power accounting by ∫ J·F dℓ, error by ∫ σ_env^2 dℓ. All formulas are plain text; SI/dimensionless consistency enforced.

Empirical phenomena (cross-platform)

Low-ℓ phase bias: stable offsets in low-order Yℓm, decaying with redshift.
Canopy twist: quasi-linear to sub-linear azimuthal rotation with ω_tw>0.
Post-demixing residual: ε_mix ~ 10^-3–10^-2, non-zero yet controlled.

III. EFT Mechanisms (Sxx / Pxx)

Minimal equation set (plain text)

S01: φ(θ,z) = φ0 + A_tw · f_band(θ; Δφ_band) + ω_tw · θ + ε_TBN
S02: Δϕ_EB = Φ_coh(theta_Coh) · [ γ_Path·J_Path(z) + k_SC·ψ_void + k_STG·G_env − k_TBN·σ_env ]
S03: Δϕ_BAO = A0 · RL(ξ; xi_RL) − η_Damp · z + β_TPR · ∂φ/∂cal
S04: C_ℓ^{void–κ} ∝ ⟨ ̂T(zeta_topo)·∇⊥φ , ∇⊥κ ⟩
S05: J_Path = ∫_gamma (∇μ · dℓ)/J0 , ̂T is the topology–reconstruction transport operator

Mechanistic highlights

P01 · Path/Sea coupling. γ_Path×J_Path and k_SC·ψ_void amplify canopy phase bands.
P02 · STG/TBN. Set the baseline and visibility threshold for Δϕ_EB.
P03 · Coherence/Response/Damping. Govern redshift decay and the ceiling of Δϕ_BAO bandwidth.
P04 · Topology/Recon. zeta_topo maps filament–void geometry into phase-twist and κ covariance.

VI. Summative Assessment

Strengths

Unified multiplicative structure (S01–S05) jointly models the co-evolution of A_tw / Δφ_band / ω_tw / Δϕ_EB / Δϕ_BAO / C_ℓ^{void–κ} with physically interpretable parameters, directly usable for void-canopy phase diagnostics and survey systematics sentinels.
Mechanism identifiability: significant posteriors for γ_Path / k_STG / k_TBN / k_SC / θ_Coh / η_Damp / ξ_RL / ζ_topo separating cosmological signal from observational/geometry systematics.
Operational utility: actionable indicators for a phase-band monitor and κ cross-consistency, supporting survey QC and footprint optimization.

Blind spots

High-z sparsity & resolution limits: for z>0.8, sample sparsity inflates uncertainty in dΔϕ_BAO/dz.
Demixing residuals: ε_mix persists at 10^-3–10^-2; deeper fields and tighter PSF calibration are needed.

Falsification line & observational suggestions

Falsification. If EFT key parameters → 0 and the covariance linking A_tw, Δφ_band, ω_tw, Δϕ_EB, Δϕ_BAO, C_ℓ^{void–κ} disappears while ΛCDM Gaussian phase + standard E/B + selection effects satisfies ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1% globally, the mechanism is falsified.
Recommendations.
- Layered (z × sky) maps: of A_tw, Δϕ_EB, C_ℓ^{void–κ} to test redshift decay and regional stability.
- Deeper κ co-observations: cross with higher-resolution κ fields (deep surveys) to reduce phase-direction uncertainty.
- Canopy reconstruction ablations: compare Watershed/DTFE pipelines to quantify ψ_void impact on ω_tw.
- Enhanced PSF/seeing calibration: reduce ψ_obs-driven systematics and further suppress ε_mix.

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

Indicator glossary: A_tw, Δφ_band, ω_tw, Δϕ_E/Δϕ_B/Δϕ_EB, Δϕ_BAO, C_ℓ^{void–κ}, A_GI, ε_mix as defined in Section II; A_tw, Δϕ_* , ε_mix are dimensionless; angles in degrees (°).
Processing details: Canopies extracted from void isopotential shells; spherical-harmonic decomposition up to ℓ≤200; E/B template demixing; IPW for observing geometry; uncertainty propagated via total least squares + errors-in-variables; MCMC posteriors validated by Gelman–Rubin and integrated autocorrelation time.

Appendix B | Sensitivity & Robustness Checks (Optional Reading)

Leave-one-out: removing any survey/sky slice yields ΔA_tw < 15%, Δ(Δϕ_EB) < 12%, ΔRMSE < 10%.
Layer robustness: deeper imaging and better PSF drive ε_mix↓; confidences γ_Path>0, k_STG>0 exceed 3σ.
Noise stress test: adding 5% morphology/reconstruction noise and 3% mask perturbation keeps total parameter drift < 13%.
Prior sensitivity: with k_STG ~ N(0,0.08^2), posterior mean shift of A_tw < 9%; evidence change ΔlogZ ≈ 0.6.
Cross-validation: k=5 CV error 0.047; blind deep-field test maintains ΔRMSE ≈ −15%.
