Initial setup and mitigation are capital-intensive (approximately $6.45M) driven by property acquisition, structural remediation/capped contingency, and a large one-time escalation reserve; ongoing operations are estimated at about $2.51M/year, driven primarily by security staff, research/monitoring personnel, and insurance/response contracts.

🚨 Major Breach $3.5M/yr
2.0% probability / year +$1.0M vs baseline
Significant containment event requiring heavy equipment, extended contractor deployments, temporary evacuations, and intensive remediation.
partial collapse or rapid sinkhole growth unauthorized entry with recovery operations requirement for large-scale shoring/excavation
🚨 Catastrophic Escalation $7.5M/yr
0.5% probability / year +$5.0M vs baseline
Severe escalation (expansion/activation) requiring major intervention, possible demolition, city-level emergency response, or martial law-level actions.

Role Count Notes
Security Officer / MTF Agent 11 [#7] Rotating 24/7 guard force (10–12 guards estimated).
Research Scientist 2 [#14] Lead + senior scientist(s) for sampling and analysis.
Research Technician / Lab Technician 2 [#14, #15] Technicians for sample handling and onsite support.

📋 Confidence Notes
Estimates use midpoints of analyst-provided ranges and split items with one-time vs recurring components; reasonable clarity on most line items but uncertainty remains around chosen mitigation strategy (cap vs shaft), insurance model, and actual frequency/severity of anomalous events, so confidence is medium.
