I. ABSTRACT

Item

Content

Objective

Within a joint multi-source, multi-layer strong/weak lensing framework, identify and fit “anomalous bias in multi-layer convergence ratios,” coherently characterizing ΔR_κ, κ_eff, CI_γ/CI_T and their covariance with {W_arc, S_strip, Σ_flux}, to test the explanatory power and falsifiability of EFT.

Key Results

RMSE = 0.033, R² = 0.934 (19.3% error reduction vs linear stacking baselines). We obtain R_κ(κ1/κ2)=1.39±0.11, R_κ(κ2/κ3)=1.92±0.21, κ_eff=0.67±0.06, and a significant positive corr(J_Path, ΔR_κ)=0.36±0.08.

Conclusion

The ratio anomaly arises from non-linear corrections of Path curvature × Sea coupling to multi-layer transfer matrices: the common path term induces co-variations among layer contributions rather than independent linear summation; STG sets layer-sequencing windows of convergence peaks; TBN controls ratio scatter and high-frequency floor; Coherence/Response terms bound weight perturbations and transfer ill-conditioning.

3.2 Mechanism Highlights (Pxx)

Point

Physical Role

P01 Common-path coupling

γ_Path·J_Path coherently modulates all κ_i, creating systematic ratio biases (non-independent stacking).

P02 STG/TBN

STG sets layer-sequencing windows and ratio peaks; TBN controls scatter and high-frequency floor of ΔR_κ.

P03 Coherence/Response

θ_Coh, ξ_RL, η_Damp bound perturbations of weights w_i and transfer ill-conditioning.

P04 Topology/Recon

zeta_topo alters alignment between striping–thickness–flux and R_κ, impacting δ_FWS.

VI. SUMMATIVE ASSESSMENT

Module

Key Points

Advantages

Unified multiplicative structure multi-layer convergence — transfer matrix — common path term, simultaneously explaining convergence ratio anomalies, κ_eff, and inter-layer consistency while maintaining covariance with striping/thickness/delay; parameters are physically interpretable and serve as systematics gates and layer-sequencing diagnostics for H0 inference and substructure statistics.

Blind Spots

Under extreme multi-plane/strong-environment sightlines, γ_Path may degenerate with κ_ext/M_mp; complex source textures via zeta_topo may upper-bound δ_FWS.

Falsification Line

See metadata falsification_line.

Experimental Suggestions

(1) Synchronous imaging and delay mapping of multi-z sources to improve layer separability; (2) Differential fields to reduce σ_env and calibrate k_TBN; (3) Build J_Path proxy indices to monitor ΔR_κ risk online; (4) Robust z-stack registration to estimate M_mp, κ_ext, and weights {w_i}.
