// by IIceMapValidationRuleDAL.GetEnabledValidatorKeysAsync for the IceMap being executed.
//
// Interface note: ParsedImportDataSetDTO is threaded in alongside the resolved row so
// HeaderFieldExistenceValidator can check raw column presence (the resolved row's Fields are
// already coerced/keyed by DestinationMemberMemberName, not raw source headers, so it has no other
// way to see the original file's columns) — a deliberate, minimal refinement of the interface
// shape the plan sketched, documented here rather than silently deviating.
