⚡ Cost Scenarios
📊 Baseline (baseline) $2.4M/yr
93.5% probability / year
Normal uneventful year with routine monitoring, maintenance, research and staffing at planned levels.
no anomalous escalation routine maintenance and research
🚨 Minor Incident $2.4M/yr
5.0% probability / year +$50K vs baseline
Localized damage or short-duration anomalous activation requiring small repairs, MTF rapid-response deployment and downtime.
single-trunk damage short MTF deployment minor equipment repair
🚨 Major Breach $2.7M/yr
1.0% probability / year +$300K vs baseline
Significant anomalous event with extended high-decibel output or storm-driven activation causing personnel injuries, structural repairs and larger remediation.
extended high-output activation multiple-trunk damage medical treatment & heavy-equipment repair
🚨 Catastrophic Breach $4.4M/yr
0.5% probability / year +$2.0M vs baseline
Public exposure or catastrophic escalation requiring large-scale emergency response, potential site relocation or long-term remediation and legal action.
widespread public exposure extended multi-day anomalous weather major legal/relocation expenses

📋 Confidence Notes
Line items are granular and many mid-range estimates are available, but large uncertainties remain in land-price variance, locale-dependent permitting costs, and unpredictable anomaly-driven escalations; contingency allowances reflect that uncertainty.
