    # Runs inside the target application via `rails runner`. Requires only the
    # standard library beyond what the app already loads, and is held to a Ruby
    # 2.6 syntax floor because it runs in the app's Ruby, not pinspec's.
    #
    # Every case is wrapped in the plan's isolation regime and reversed
    # afterwards. Nothing here writes outside a transaction unless the plan says
    # the suite is untransacted, in which case the tables it touched are
    # truncated instead.
