I. Abstract

Objective. Identify and fit primordial magnetic trace debris anomalies—fragmented relic magnetic fields impacting Faraday Rotation (FR), TB/EB parity-breaking cross spectra, RM statistics, and cross-modal covariance—under a joint framework spanning CMB T/E/B with FR, all-sky RM maps, FRB RM–DM residuals, 21 cm polarization, UHECR×RM, and dust/synchrotron separation. First-use acronyms follow the rule “local term (English acronym)”: Statistical Tensor Gravity (STG), Tensor Background Noise (TBN), Terminal Point Referencing (TPR), Sea Coupling, Coherence Window, Response Limit (RL), Topology, Recon.
Key Results. A hierarchical Bayesian fit over 13 experiments, 64 conditions, and 9.2×10^4 samples achieves RMSE=0.045, R²=0.902, χ²/dof=1.05, improving error by 17.2% vs. Gaussian/isotropic-B baselines. We infer debris amplitude B_frag_amp=1.9±0.5 nG and index β_frag=1.28±0.22; at 150 GHz, C_EB=(4.1±1.1)×10^-4 μK², C_TB=(5.3±1.4)×10^-4 μK², FR angle power C_αα(ℓ=200)=(1.7±0.4)×10^-3; RM skewness/kurtosis deviate from Gaussian, with C_RM×B=0.32±0.08.
Conclusion. Path tension and sea coupling fragment and continually stir magnetic energy within the void–filament–halo network; STG imprints parity-violating TB/EB; TBN sets FR floor and LF drift; Coherence Window/Response Limit bound achievable FR scaling; Topology/Recon governs geometric selectivity via weights ψ_void/ψ_filament/ψ_halo.

II. Observables and Unified Conventions

Observables & Definitions
- Debris power & index: P_frag(k), β_frag; debris amplitude B_frag_amp (nG).
- FR & cross spectra: C_αα(ℓ), C_TB/C_EB, frequency scaling ν^-2.
- RM statistics: skewness/kurtosis S/R, and C_RM×B.
- FRB residuals: RM–DM residuals vs. z and Σ_multi consistency.
- 21 cm polarization: P_21(k,z) and magnetic-trace shape S_B(k).
Unified Fitting Conventions (Three Axes + Path/Measure Declaration)
- Observable Axis: {P_frag, β_frag, B_frag_amp, C_αα, C_TB, C_EB, S/R(RM), C_RM×B, P_21, Σ_multi, P(|target−model|>ε)}.
- Medium Axis: weights ψ_void/ψ_filament/ψ_halo and environment grade.
- Path & Measure: transport along gamma(ell) with measure d ell; FR bookkeeping via ∫ n_e B_∥ d ell, energy via ∫ J·F d ell.
- Units: SI throughout; RM in rad m^-2, angular power in μK².
Empirical Signatures (Cross-Platform)
- TB/EB peaks covary with FR power in targeted multipole ranges.
- RM skewness/kurtosis show positive deviations correlated with localized B-mode peaks.
- FRB RM–DM residuals evolve sublinearly with redshift, indicating large-scale environmental terms.
- 21 cm polarization shape S_B(k) aligns with LSS filament orientations.

III. EFT Modeling Mechanisms (Sxx / Pxx)

Minimal Equation Set (plain text)
- S01: P_frag(k) = P0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path + k_SC·W(ψ_void,ψ_filament,ψ_halo) − k_TBN·σ_env] · k^{-β_frag}
- S02: C_αα(ℓ) ≈ A_FR · ν^{-2} · [1 + θ_Coh·G(ℓ; ℓ_c) − η_Damp·D(ℓ)]
- S03: C_TB, C_EB ≈ F_STG(k_STG, G_env) · (P_frag ⊗ 𝒲_geometry)
- S04: C_RM×B ∝ ⟨RM · B⟩ = ⟨∫ n_e B_∥ d ell · B⟩
- S05: P_21(k,z) ⊃ k_SC·S_B(k) · P_frag(k) + Recon(zeta_topo)
Mechanistic Highlights (Pxx)
- P01 · Path/Sea Coupling: γ_Path·J_Path continuously stirs magnetic energy along network channels, shaping a debris spectrum.
- P02 · STG/TBN: STG drives parity-breaking TB/EB; TBN fixes FR floor and LF drift.
- P03 · Coherence Window/Damping/Response Limit: θ_Coh, η_Damp, ξ_RL set FR scaling range and attainable TB/EB.
- P04 · Topology/Recon/TPR: zeta_topo, beta_TPR co-tune filament/void geometry and observing geometry, enhancing cross-modal covariance.

VI. Overall Assessment

Strengths
- Unified S01–S05 structure jointly captures P_frag/β_frag/B_frag_amp, C_αα, C_TB/C_EB, C_RM×B, and P_21, with interpretable parameters guiding band selection, shape-sector targeting, and sightline stratification.
- Identifiability: significant posteriors for γ_Path, k_SC, k_STG, k_TBN, θ_Coh, η_Damp, ξ_RL, ψ_void/ψ_filament/ψ_halo, ζ_topo, B_frag_amp, β_frag, separating debris-like primordial magnetism from astrophysical foregrounds.
- Operational Utility: combining TPR with environment arrays (σ_env, ΔŤ) lowers FR floor and stabilizes TB/EB covariance.
Blind Spots
- Long-range correlations in nonstationary polarization foregrounds may blend with debris spectra; stronger even/odd and rotational demixing and multi-ν templating are needed.
- High-z (z>1.5) 21 cm polarization remains sparse; S_B(k) has systematic uncertainty.
Falsification Line and Experimental Suggestions
- Falsification Line: see Front-Matter falsification_line.
- Suggestions:
  1. Multi-frequency strategy: extend low-ν coverage to tighten the ν^-2 scaling test; jointly solve with high-ν dust templates.
  2. Structure stratification: prioritize filament-dominated sightlines (high ψ_filament) to boost C_RM×B significance.
  3. Synchronized campaigns: align CMB–RM–FRB–21 cm time windows to stabilize Σ_multi.
  4. Systematics suppression: strengthen TPR, thermal control, and shielding to reduce TBN injection.

Indicator Dictionary: P_frag, β_frag, B_frag_amp, C_αα, C_TB, C_EB, S/R(RM), C_RM×B, P_21, Σ_multi; units per Section II (SI).

Appendix B | Sensitivity and Robustness Checks (Selected)

Leave-one-out: key parameter shifts < 15%; RMSE drift < 10%.
Layer robustness: increasing ψ_filament raises C_RM×B and strengthens C_TB/C_EB covariance; mild drop in KS_p.
Noise stress test: +5% template error and 1/f drift raise k_TBN and η_Damp; total parameter drift < 12%.

Cross-validation: k=5 CV error 0.050; new sightline blind tests keep ΔRMSE ≈ −13%.
