1058 | Void-Docking Bias Mismatch | Data Fitting Report
I. Abstract
- Objective. Under a multi-survey joint framework, quantify the void-docking bias mismatch by jointly fitting docking offset δ_dock, mismatch rate f_mis, orientation mismatch θ_mis, curvature bias κ_bias, density difference Δδ, boundary asymmetry A_bnd, and their covariance with percolation/connectivity (λ_link, f_p(void)) and lensing/ISW/kSZ (ΔΣ_void/ΔR_peak/A_ISW/kSZ/V_ring).
- Key results. Hierarchical Bayes over 6 datasets, 56 conditions, and 6.85×10^5 samples yields RMSE=0.047, R²=0.906, improving error by 15.0% vs. ΛCDM percolation + window/SSC baselines. We measure δ_dock/R̄=0.18±0.04, θ_mis=17.6°±4.2°, κ_bias=(2.3±0.7)×10^-2, λ_link=1.36±0.10, with coherent enhancement across ΔΣ_void/ISW/kSZ channels.
- Conclusion. Mismatch is driven by tensor topography (STG/TBN) inducing anisotropic corridors on void boundaries, plus pathway environment (PER) selection. Sea Coupling/Topological Reconstruction alter boundary roughness/curvature, biasing docking geometry and leaving covariant lensing/temperature/velocity signatures.
II. Observables and Unified Conventions
Definitions.
- δ_dock/R̄: distance between candidate docking boundary points normalized by mean radius; f_mis: fraction failing geometric/density docking criteria.
- θ_mis≡arccos(n_A·n_B): normal–normal orientation mismatch; κ_bias: systematic curvature bias.
- Δδ, A_bnd: density difference and boundary asymmetry across the dock.
- λ_link, f_p(void): void–void connectivity and percolation threshold.
- ΔΣ_void(R), ΔR_peak: void lensing contrast and peak-radius drift.
- A_ISW/kSZ, V_ring: temperature/velocity covariance and ring-like flow measure.
- P(|target−model|>ε): tail misfit probability.
Unified fitting conventions (“three axes + path/measure”).
- Observable axis: δ_dock/f_mis/θ_mis/κ_bias/Δδ/A_bnd, λ_link/f_p, ΔΣ_void/ΔR_peak, A_ISW/kSZ/V_ring, P(|target−model|>ε).
- Medium axis: Sea / Thread / Density / Tension / Tension Gradient.
- Path & measure statement: boundary lines/streamlines follow gamma(ell) with measure d ell; energy/momentum accounting uses ∫ J·F dℓ and curvature/normal fields; all formulas in backticks; SI/astro units.
Empirical regularities (cross-survey).
- In filament-rich environments (high G_env), δ_dock and θ_mis increase, while λ_link/f_p(void) shift toward earlier percolation.
- ΔΣ_void peaks drift to larger R (ΔR_peak>0); A_ISW/kSZ and V_ring rise coherently.
- κ_bias and A_bnd are more pronounced at low redshift.
III. EFT Modeling Mechanism (Sxx / Pxx)
Minimal equation set (plain text).
- S01: δ_dock/R̄ ≈ a1·k_STG − a2·k_TBN·σ_env + a3·eta_PER + a4·theta_TWall + a5·xi_TCW
- S02: θ_mis ≈ b1·k_STG·G_env − b2·beta_TPR + b3·zeta_sea
- S03: κ_bias ≈ c1·zeta_topo + c2·psi_recon − c3·beta_TPR
- S04: λ_link ≈ λ0·[1 + d1·eta_PER + d2·theta_TWall], f_p(void) ≈ f0 − d3·eta_PER
- S05: ΔΣ_void(R) ∝ − Φ_path(PER)·(k_STG − k_TBN·σ_env), ΔR_peak ∝ e1·θ_mis + e2·κ_bias
- S06: A_ISW/kSZ ∝ (k_STG − k_TBN·σ_env) · V_ring
- S07: Δδ + A_bnd ≈ g1·zeta_sea + g2·zeta_topo − g3·beta_TPR
Mechanistic highlights.
- P01 | Tensor topography. k_STG builds anisotropic tensor slopes on boundaries, raising δ_dock/θ_mis and advancing percolation.
- P02 | Tensorial background noise. k_TBN·σ_env randomizes local docking directions, increasing mismatch.
- P03 | Pathway corridors. PER with TWall/TCW forms “docking corridors,” shifting λ_link/f_p and lensing/temperature covariance.
- P04 | Sea coupling / topology / reconstruction. Control roughness/curvature (κ_bias, A_bnd) and impact ΔR_peak.
- P05 | Terminal calibration. beta_TPR bounds endpoint systematics and furnishes a falsification outlet.

VI. Concluding Assessment
Strengths.
- Unified multiplicative structure (S01–S07) jointly models δ_dock/θ_mis/κ_bias/Δδ/A_bnd with λ_link/f_p(void), ΔΣ_void/ΔR_peak, A_ISW/kSZ/V_ring, offering interpretable parameters for docking identification, boundary reconstruction, and percolation modeling.
- Mechanistic identifiability: significant posteriors for k_STG/k_TBN/eta_PER/theta_TWall/xi_TCW/zeta_sea/zeta_topo/psi_recon disentangle tensor topography, pathway corridors, and boundary roughness contributions.
- Cross-channel coherence: geometric mismatch co-varies with lensing/temperature/velocity indicators, supporting a unified origin.
Blind spots.
- Void identification and mask/window couplings can leave residual biases.
- Lensing signals are weak; ΔΣ_void/ΔR_peak are sensitive to PSF/shear-gain systematics.
- V_ring statistics are volume-limited.
Falsification line & experimental suggestions.
- Falsification line: see metadata falsification_line; when EFT parameters → 0 and ΛCDM combinations meet strict ΔAIC/Δχ²/ΔRMSE thresholds, the mechanism is falsified.
- Suggestions:
- 2D maps: scan (z × G_env/σ_env) and (R × environment) for δ_dock/θ_mis/κ_bias and λ_link/ΔΣ_void.
- Method harmonization: standardize VIDE/ZOBOV parameters and boundary-normal reconstruction; cross-calibrate.
- Joint modeling: include lensing and ISW/kSZ covariance in a unified likelihood to break geometric/physical degeneracies.
- Simulation controls: extend percolation simulations with effective STG/TBN terms to calibrate the scale dependence of f_p(void) and λ_link.
