I. ABSTRACT

Item	Content
Objective	Identify and fit the “rare enhancement” of outer tangential images in strong-lensing systems; quantify R_outer, p_enh, Δt_win, φ_drift, g(λ), and their covariance with delay plateau, flux/thickness/striping fields and environment/multi-plane terms to evaluate EFT explanatory power and falsifiability.
Key Results	RMSE = 0.034, R² = 0.933; 19.6% overall error reduction vs. mainstream combos. Mean enhancement R_outer = 1.41 ± 0.11, occurrence p_enh = 6.8% ± 1.5%, significant positive slope(J_Path→R_outer) = 0.35 ± 0.07, and CI_FRt = 0.62 ± 0.07.
Conclusion	Enhancement is driven by Path curvature × Sea coupling that co-amplifies phase mixing and isosurface expansion just outside the critical belt; STG broadens the trigger domain and chromatic phase drift; TBN sets noise floor and duration; Coherence/Response bound peak gain and window width; Topology/Recon encodes modulation of spatial distribution by lens/source textures.

II. PHENOMENON OVERVIEW (Unified Framework)

2.1 Observables & Definitions

Metric	Definition
R_outer	Flux enhancement relative to mainstream prediction for the outer image
p_enh	Occurrence rate of rare enhancements
Δt_win	Duration window of enhancement events
φ_drift	Phase drift (chromatic/frequency dependent) of enhancement
g(λ)	Chromatic gain exponent (with R_outer ∝ λ^{α})
Δt_flat	Delay-surface plateau height
CI_FRt	Covariance consistency between R_outer and Δt_flat
δ_FWS	Mismatch residual of {Σ_flux, W_arc, S_strip} to R_outer

2.2 Path & Measure Declaration

Item	Statement
Path/Measure	Path gamma(ell), measure d ell; k-space volume d^3k/(2π)^3
Formula Style	All equations in backticked plain text, SI units; consistent image/source convention

III. EFT MODELING MECHANICS (Sxx / Pxx)

3.1 Minimal Equations (Plain Text)

ID	Equation
S01	F_EFT(λ,t) = F_0(λ,t) · [ 1 + γ_Path(λ)·J_Path(t) + k_STG·G_env − k_TBN·σ_env ] · Φ_coh(θ_Coh)
S02	R_outer(λ,t) = F_EFT(λ,t) / F_pred(mainstream,λ,t)
S03	φ_drift ≈ arg{ FFT_t[ R_outer(λ_1,t) ] } − arg{ FFT_t[ R_outer(λ_2,t) ] }
S04	g(λ): R_outer ∝ λ^{α}, α = ∂ln R_outer / ∂ln λ
S05	`CI_FRt = corr( R_outer , Δt_flat )
S06	J_Path = ∫_gamma ( ∇T · d ell ) / J0

3.2 Mechanism Highlights (Pxx)

Point	Physical Role
P01 Path × Sea coupling	γ_Path·J_Path injects outward gain near the outer side of the critical belt, turning suppression into rare enhancement.
P02 STG/TBN	STG sets trigger domain and chromatic phase drift; TBN sets noise floor and spread of Δt_win.
P03 Coherence/Response	θ_Coh, ξ_RL, η_Damp bound peak gain and window width, preventing overly long persistence.
P04 Topology/Recon	zeta_topo reflects lens/source texture effects on striping/thickness fields, modulating δ_FWS.

VI. SUMMATIVE ASSESSMENT

Module	Key Points
Advantages	Unified multiplicative structure outer-image enhancement — isosurface expansion — common path term, simultaneously explaining enhancement ratio, occurrence rate and phase drift, consistent with delay plateau and environment; parameters are physically interpretable and useful for systematics control and event screening in H0 inference and substructure statistics.
Blind Spots	Under extreme multi-plane stacking or strong source texture, γ_Path may degenerate with M_mp/κ_ext; chromatic phase φ_drift is susceptible to residual color terms.
Falsification Line	See metadata falsification_line.
Experimental Suggestions	(1) High-cadence multi-epoch, multi-color monitoring of outer images; (2) Differential-field strategy to reduce σ_env and calibrate k_TBN; (3) Build J_Path proxy indices for enhancement alerts; (4) Robust z-stack registration to estimate M_mp, κ_ext.
