// NOTE: the `:Data_Bank` label is required so the planner uses the
// `constraint_2cc4938c` RANGE index on `:Data_Bank(ref_id)`. Without the label
// the planner falls back to AllNodesScan + filter (462k+ DB hits per UNWIND
// row in production), which holds write locks on every matched node for
// multiple minutes per batch and blocks any concurrent
// `remove_nodes_by_files` from the standalone sync path.
