Initial capital/setup costs are estimated at approximately $22.81M, driven primarily by underground site build-out, BSL-4 lab/R&D setup and a dedicated contingency reserve. Annual recurring operations are roughly $15.78M/yr, dominated by specialized personnel (musicians, supervisors, MTF), power/facilities maintenance and ongoing research/monitoring.

⚡ Cost Scenarios
📊 Baseline (baseline) $15.8M/yr
88.0% probability / year
Normal operational year with continuous Auseuil protocol maintained and no major containment incidents.
continuous_music_maintained routine_turnover_and_maintenance
🚨 Minor Incident $16.8M/yr
10.0% probability / year +$1.0M vs baseline
Localized interruption or short-term failure (e.g., brief lapse in music, localized SCP-4140-2 manifestation) requiring emergency response, replacement musicians, small blocking operation and extra medical treatment.

🚨 Major Breach $45.8M/yr
2.0% probability / year +$30.0M vs baseline
Significant spread of SCP-4140-2 requiring large-scale engineering interventions, large use of contingency capital, mass evacuations and extensive legal/cover-up operations.

📋 Confidence Notes
Many cost drivers are well-described (personnel, facilities, power) allowing medium confidence in recurring estimates; uncertainty remains around mortality rates, frequency/scale of blocking operations, and BSL-4 lab/contingency sizing which prevent high confidence.
