    audits: { open: 0, findings: 0 },
  }

  // Policies
  var ga = new GlideAggregate("sn_compliance_policy")
  ga.addAggregate("COUNT")
  ga.groupBy("state")
  ga.query()

  while (ga.next()) {
    var count = parseInt(ga.getAggregate("COUNT"), 10)
    summary.policies.total += count
    if (ga.getValue("state") === "published") {
      summary.policies.published = count
    }
  }

  // Risks by rating
  ga = new GlideAggregate("sn_risk_risk")
  ga.addQuery("active", true)
  ga.addAggregate("COUNT")
  ga.groupBy("residual_risk_rating")
  ga.query()

  while (ga.next()) {
    var rating = ga.getValue("residual_risk_rating")
    var riskCount = parseInt(ga.getAggregate("COUNT"), 10)
    if (summary.risks.hasOwnProperty(rating)) {
      summary.risks[rating] = riskCount
    }
  }

  return summary
}

Example Workflow

// 1. Query active policies
await snow_query_table({
  table: "sn_compliance_policy",
  query: "state=published",
  fields: "name,category,effective_date,review_date",
})

// 2. Find high risks
await snow_query_table({
  table: "sn_risk_risk",
  query: "residual_risk_rating=high^ORresidual_risk_rating=critical",
  fields: "name,category,residual_risk_score,owner",
})

// 3. Get compliance summary
await snow_execute_script_with_output({
  script: `
        var summary = getComplianceSummary();
        gs.info(JSON.stringify(summary));
    `,
})

Best Practices

1. Clear Ownership - Assign policy/control/risk owners
2. Regular Reviews - Schedule periodic assessments
3. Evidence Collection - Document control effectiveness
4. Risk Quantification - Use consistent scoring
5. Audit Trail - Track all changes
6. Automation - Automate testing where possible
7. Reporting - Regular compliance dashboards
8. ES5 Only - No modern JavaScript syntax
