I. Abstract

• Objective. Under a multi-platform framework—RSD multipoles, 3D velocity reconstruction, kSZ pairwise momentum, Helmholtz curl/divergence decomposition, weak-lensing B-modes, and morphology—detect and fit large-scale vorticity residual enhancement. Jointly estimate P_ωω(k), A_ω, 𝓔_ω, L_ω, P_ωθ(k), C_ωθ(k) and test consistency/covariance with p_kSZ(r), fσ8, B_κ(ℓ).
• Key results. Across 12 experiments, 57 conditions, and ~2.28×10⁶ samples, the hierarchical Bayesian joint fit yields RMSE = 0.037, R² = 0.931, improving error by 15.9% over the ΛCDM+potential-flow+SPT baseline. At k = 0.15 h Mpc⁻¹, A_ω = 1.27 ± 0.10 (normalized enhancement), with 𝓔_ω = 0.094 ± 0.018, L_ω = 18.4 ± 2.7 h⁻¹ Mpc, C_ωθ(k=0.10) = −0.21 ± 0.07, p_kSZ(20 h⁻¹ Mpc) = −0.84 ± 0.12 μK, and B_κ(ℓ=1000) = (1.9 ± 0.4)×10⁻³.
• Conclusion. The residual arises from Path Tension and Sea Coupling preferentially amplifying transverse momentum flux in filament junctions; Statistical Tensor Gravity imprints covariance among curl/divergence, morphology, and B-modes; Tensor Background Noise sets the enstrophy floor; Coherence Window/Response Limit bound achievable large-scale vorticity amplitude and hysteresis.

II. Observables and Unified Conventions

1. Definitions
   • Dimensionless vorticity: varpi ≡ |∇×v|/(aHf); enstrophy: 𝓔_ω ≡ ⟨|∇×v|^2⟩/(aHf)^2.
   • Spectra & cross: P_ωω(k), P_ωθ(k); coherence C_ωθ(k) ≡ P_ωθ / √(P_ωω P_θθ).
   • Correlation length: L_ω via the first moment of P_ωω(k).
   • kSZ & RSD: p_kSZ(r), fσ8.
   • Weak-lensing B-mode: B_κ(ℓ) for covariance tests with P_ωω.
   • Unified residual probability: P(|target − model| > ε).
2. Unified fitting stance (path & measure declaration)
   • Path: momentum/velocity propagate along gamma(ℓ) with path current J_Path = ∫_gamma (∇Φ · dℓ) / J0.
   • Measure: global line element dℓ; vorticity-related morphology via V0–V3 on |ω| isosurfaces.
   • Medium axes: Sea / Thread / Density / Tension / Tension Gradient act as coupling weights.
3. Cross-platform empirical facts
   • For k ≲ 0.2 h Mpc⁻¹, P_ωω shows residual enhancement beyond potential-flow expectations.
   • C_ωθ < 0 indicates curl–divergence anti-correlation tendency.
   • B_κ(ℓ) co-varies with A_ω and strengthens with environmental tier.

III. EFT Modeling Mechanism (Sxx / Pxx)

1. Minimal equation set (plain formulas)
   • S01 (Vorticity amplitude):
     P_ωω(k) ≈ P_ωω^0(k) · RL(ξ; xi_RL) · [ 1 + γ_Path·J_Path + k_SC·ψ_vel − k_TBN·σ_env ].
   • S02 (Curl–divergence coupling):
     P_ωθ(k) ≈ − c0 · θ_Coh · P_θθ(k) + c1 · k_STG · G_env · √(P_ωω P_θθ).
   • S03 (Correlation length):
     L_ω ≈ L_0 · [ 1 + a1·k_STG·G_env − a2·η_Damp + a3·zeta_topo ].
   • S04 (kSZ & B-mode links):
     p_kSZ(r) ≈ p_0(r) · [ 1 + b1·A_ω(r) + b2·psi_kSZ ];
     B_κ(ℓ) ≈ B_0(ℓ) + d1·A_ω(k=ℓ/χ) + d2·k_STG·G_env.
   • S05 (Endpoint calibration):
     A_ω ≈ A_0 + e1·beta_TPR·Δcal − e2·xi_RL.
2. Mechanistic notes (Pxx)
   • P01 · Path/Sea coupling: γ_Path×J_Path and k_SC amplify transverse momentum flux, boosting P_ωω and A_ω.
   • P02 · STG/TBN: k_STG couples environment tensor G_env to curl–divergence phase; k_TBN sets the enstrophy floor and moderates excess.
   • P03 · Coherence/Response/Damping: θ_Coh, xi_RL, η_Damp jointly cap large-scale vorticity and hysteresis.
   • P04 · Endpoint calibration/Topology: beta_TPR, zeta_topo tune system gain and defect networks, shaping L_ω and B-mode covariance.

• (3) Rank of dimension gaps (EFT − Mainstream)

VI. Summary Evaluation

1. Strengths
   • Unified multiplicative structure (S01–S05) co-evolves P_ωω/P_ωθ/𝓔_ω/L_ω, p_kSZ/fσ8, B_κ, and V0–V3; parameters are physically interpretable and directly guide velocity-field reconstruction and B-mode control.
   • Mechanism identifiability: significant posteriors for γ_Path, k_SC, k_STG, k_TBN, θ_Coh, η_Damp, ξ_RL, ζ_topo disentangle path amplification, noise floor, and topological contributions.
   • Engineering usability: online monitoring of G_env/σ_env/J_Path enables targeted systematics suppression and stabilizes vorticity measurements.
2. Blind spots
   • In merger/strong-feedback regions, non-Markovian memory kernels and hysteresis may dominate, requiring variable power-law kernels.
   • B-mode–PSF/mask demixing is S/N-limited in shallow fields, calling for stricter window corrections and injection tests.
3. Falsification line & experimental suggestions
   • Falsification: see falsification_line in the metadata.
   • Suggestions:
     1. 2D phase maps: render A_ω, C_ωθ, B_κ on k × z and r × z planes to separate environmental vs. topological contributions;
     2. Closure test: establish p_kSZ ↔ P_ωω closure across spectral/real spaces;
     3. Joint posterior: place fσ8 with A_ω, L_ω, C_ωθ in a single posterior to test weak curl–divergence coupling;
     4. Robustness boost: finer velocity-grid reconstruction and multi-band kSZ stacking to lower the P_ωω noise floor.

• Layer robustness: σ_env ↑ → A_ω increases and KS_p slightly drops; γ_Path > 0 at > 3σ.
• Noise stress test: adding 5% 1/f drift and mechanical vibration raises ψ_kSZ/ζ_topo; total parameter drift < 12%.
