  "limitations": [
    "One-host remote submission with one TaskManager JVM; not separate TaskManager JVMs for every subtask.",

    "Both processes explicitly enable the flag; inconsistent planner/task flags are not admitted by this evidence.",
    "No performance claim; 1.18 uses matching copied candidate Java sources and the pinned candidate library."
