    • Applies an OutputMappingConfig against a work result. Single-primary-key entities only (composite keys throw a clear error). Field/child values are resolved from the result via the shared resolver, so "$.path" reads result.path.

      Dry-run (dryRun: true): the mapped values are still resolved and the target entity/field metadata is still validated, but NO entity is saved and NO child is created — the would-be values are returned in previewFields / previewChild so a dry-run preview can show exactly what an apply would write. This is what lets a dry-run of any wrapped work type (Action / Agent / Infer / ML Model) compute its effect without mutating data, mirroring the FieldRulesProcessor dry-run preview.

      Parameters

      Returns Promise<WriteBackResult>
