        The :class:`ResumeDispatcher` (HITL-03 §1) routes a recorded decision
        back to

        the right continuation by this value: a workflow ``ApprovalNode``
        resumes an

        edge (``WORKFLOW_NODE``); a Policy/tool-level gate resumes a partial
        turn

        (``TOOL_CALL``). Persisted to a ``VARCHAR(20)`` — a StrEnum serializes
        to its

        string value, so it needs no migration.
