+`_capture`でOperationsCoordinatorをis_instance_validで分岐し、実nullと正式保存値`coordinator: {}`を区別する。
+全Runtime snapshotは無加工で保持する。fixtureでOperationsをenableせず、既存の境界・保存・replay判定を維持する。
+同GD全体を静的確認し、OperationsCoordinatorの直接呼出しはこの分岐内の2件のみ。
+reservation/request/task/shift、FileAccess、DirAccessには既存のnullガードがある。
+facility/definition/service/guest/worker、_inventory/_request/_worker/_taskの直接参照は既存fixtureの生成・取得成立が前提である。
+これらの前提が崩れた場合のnullリスクは残るが、任意機能Operationsの無効化による同種の無条件アクセスは他にない。
+本修正版のRoot fresh r02 nativeは未実測。workerはcode-ready提出のみで受入・readinessを確定しない。
