runbookUrl input renamed to referenceUrl (old key still accepted). Output column is now referenceUrl; runs that still send the old input key also get the old column, which will be removed in a later version.
Charging: each row is saved to the dataset first and charged only after the save succeeds (shared runner). A failed save is never charged; a charging error after a saved row stops the run without adding an error row.
New rowId column (stable per domain) so the uncharged error row written after a save timeout can be matched to the saved row and removed.
Run summary (OUTPUT) adds chargeErrors.
Summary report: REPORT is saved before report-summary is charged; a failed save is never charged, and if the charge is refused the report is removed.
Budget guard: free results (NXDOMAIN, DNS errors) ahead of the max-charge limit no longer stop the run early; every domain your budget covers is audited.
