    "外部收敛与剪切：将环境/LOS 结构压缩为有效 `κ_ext, γ_ext`，以模拟时延 `Δt ∝ (D_Δt/c)·φ(θ)`；空洞（欠密）沿 LOS 提供 `κ_ext<0` 的系统偏置，影响 H0 推断与时延残差。",
    "环境统计与校正：通过 `δ_g`、`n_{gal}`、弱透镜 `κ_κ`、2M++/SDSS/HSC 体密度等构建环境权重或回归校正，假设 LOS 结构近似独立、相干尺度有限。",
    "退化与不确定性：质量片退化（MSD）、源位与势模型耦合、时变/微透镜、PSF/配准与时延测光系统学，导致 `Δt` 与环境指标之间的相关被弱化或误判。",
    "观测系统学：扇区/空洞识别阈、红移完备度、光度极限、射线追踪栅格与先验选择均能改变 `κ_ext` 与空洞度估计的显著性。"
