  "reason": "The exact cover is retained but a prescriptive selector was not located. A finite transport test can examine a constrained structural explanation without enlarging the census or fitting a selection rule.",

    "No new endpoints, anchors, bridges or phase states",
    "No cumulative/upstream Gear operation",
