Scenario: Handling a corrupted file with invalid checksum Given a file named "sp5001.bin" exists in the staging directory And the file content has been corrupted And the calculated checksum does not match the header checksum When I initiate the binary ingestion process Then the system should halt the ingestion process And the system should raise a "DataIntegrityError" And the file should be moved to "/data/error" And an alert with priority "High" should be sent to the Data Engineering team
