bem_matching_plane_zhao Module

Matching-plane 用の charge-driven Zhao 外部シース応答。

応答は整合面直下の D_z/eps0 を外部側 interface field とみなし、 上流の準中性条件と Sagdeev 積分を満たす A/B/C branch を解く。 定常表面電流の零電流条件は課さないため、BEACH 側の帯電過程を消去しない。 平面・半無限の外部問題は z 方向に並進対称なので、絶対高度 H は数値式に 入らず、runtime がこの応答を domain の z-high gauge へ結び付ける。 既定policyはqueryごとにstatelessで、opt-inのType A continuationだけが 呼出側から渡されたaccepted endpoint rootをseedとして使う。 この module は公開型と評価の入口を持ち、物理式を physics、Newton 法を numerics、根の選択と継続を roots の非公開 submodule へ委譲する。
