How CTI / blue team should read this

  • Prefer the full SCORECARD over quick for operational decisions.
  • Check δ_C carefully — values below 1.0 mean the Safety Gate reduced composite UHQS.
  • Module C is harness visibility, not your SIEM pipeline; wire log shipping yourself.
  • See READING-UHQS.md for module A–F interpretation.
