    "潮汐扭矩与自旋—轨道共振：`Ω_prec/Ω_pat ≈ m:n` 时可能发生相位捕获；盘条纹/棒的图样速度 `Ω_pat` 与卫星轨道进动 `Ω_prec` 接近时提升停留时间与对齐概率。",
    "三轴势与进动：非球对称主晕导致轨道结点与近心线进动；进动率受 `q≡M_sat/M_host`、轨道倾角与半径控制。",
    "动力摩擦与共振漂移：`t_df ∝ V_c R^2/(G m_sat lnΛ)`；摩擦使轨道半径缓慢衰减并穿越共振带，存在“捕获—逃逸”竞争。",
    "盘—晕耦合与对齐：宿主盘自旋与宇宙网丝状结构存在统计对齐；卫星轨道极向分布受宿主形状/自旋影响。",
    "观测系统学：分群/去混淆、主轴/图样速度测定、投影几何、星流与低表面亮度结构的检测阈值影响锁定分数估计。"

    "EFT 前向：引入 Path（丝状能/角动量通道提升相位牵引）、TensionGradient（∇T 重标 `Ω_prec` 与潮汐项）、CoherenceWindow（相位/时间相干 `L_coh,φ/L_coh,t`）、Mode/SeaCoupling（环境触发）、Damping（跨相阻尼）、ResponseLimit（锁定上下限 `f_floor_lock/f_cap_lock`），幅度由 STG 统一；Recon 重构几何与探针选择耦合。"
