+ How to verify: Every number on this page was generated live by the server responding to your browser request. + Hit refresh — the queries run again. These are not cached or pre-computed. The SQL tests execute on ${totalRows.toLocaleString()} real rows. + The hybrid search finds real workers with real names, skills, and certifications — every result marked sql_verified: true. +
