Problem

The SRE team is triaging compound error conditions where multiple signals fire at once. An error record is flagged if it matches more than one of these: err_type contains 'Error', message contains 'null', svc_name contains 'api', severity is 'error' or 'ERROR'. Return all flagged rows with their error ID, type, message, service, severity, occurrence count, and first occurrence time.
