      G-019 Layer C surface for the escalation-drift scanner (T-1555).
      The daily <code>escalation-drift-daily</code> cron scans completed tasks
      for symptom-fix candidates: <strong>H1</strong> (bug-class without
      <code>## RCA</code>), <strong>H2</strong> (same learning ID repeated
      across 3+ tasks in 30 days), <strong>H3</strong> (bug-class without
      RCA AND no learning capture).
