⚡ Cost Scenarios
📊 Baseline (baseline) $1.8M/yr
91.0% probability / year
Normal year with active containment posture, no major incidents.
no incidents routine monitoring planned maintenance
🚨 Minor Incident $2.0M/yr
8.0% probability / year +$185K vs baseline
Localized incident similar to 4920-A requiring investigation, additional repairs, counseling and targeted testing.
sensor failure in fog temporary loss of subject limited site damage needing repair
🚨 Major Breach $3.2M/yr
1.0% probability / year +$1.4M vs baseline
Significant breach/recurrence requiring large-scale response, legal/PR mobilization, and potential decommissioning/cleanup.
widespread personnel exposure public exposure / whistleblower reactivation or spread of anomalous effects

📋 Confidence Notes
Analyst notes provide detailed line-item ranges for most categories, enabling midpoint estimates; uncertainty remains due to wide one-time ranges (esp. contingency/legal reserves), unknown recurrence likelihood of anomalous behavior, and discretionary decisions about posture (active containment vs. minimal monitoring).
