Use whenever the user wants to validate or reconcile loaded data against the source API, check row counts or control totals, verify a load was complete, or confirm that warehouse data matches what the API returned — even if they don't say "validate". Trigger phrases include: "did everything land?", "check the counts", "reconcile the table", "verify the load", "compare API vs warehouse", "are the rows correct?", or any request to confirm that a loaded table matches its source.
