⚡ Cost Scenarios
📊 Baseline (baseline) $41.0M/yr
89.0% probability / year
Normal operational year with no major incidents; routine containment, monitoring, and tourism/heritage management as budgeted.
no major breaches routine astronomical events handled as planned
🚨 Minor Incident $43.0M/yr
8.0% probability / year +$2.0M vs baseline
Limited containment incident (e.g., localized exposure, failed sensor, vehicle/detector damage) requiring emergency response, medical treatment, and short-term repairs.
localized breach equipment failure small-scale public exposure
🚨 Major Breach $66.0M/yr
2.0% probability / year +$25.0M vs baseline
Significant containment breach (e.g., lunar-eclipse correlated mass emergence or major reality-displacement event) causing casualties, large equipment loss, legal/public-relations costs and partial site rebuild.
lunar eclipse related displacement mass SCP-5536-2 emergence major infrastructure damage
🚨 Full Physical Containment $121.0M/yr
1.0% probability / year +$80.0M vs baseline
Strategic decision-year to pursue heavy permanent containment (domes/encasement, full shielding, large-scale civil works) in response to risk escalation or policy decision.
policy/O5 mandate unacceptable incident frequency new research indicating necessity of active shielding
👥 Personnel 84 total
Role Count Notes
Security Officer / MTF Agent 75 Operational payroll pool to maintain at least 20 armed personnel on site 24/7 (≈70–80 total active guards / supervisors / backfill) [#4].
Research Scientist 9 Physicists, radiochemists, astronomers, conservators and data analysts represented as research FTEs (6–12 FTEs total in analyst notes) [#20].
📋 Confidence Notes
High uncertainty driven by the national/heritage value of Stonehenge (item #1, #24) and the wide ranges for land/legal settlements, tourism compensation and full-shielding options; anomalous behavior (eclipse-driven breaches) adds episodic heavy-tail risk. Estimates use midpoints of analyst ranges and assume an exclusion-first posture for baseline containment.
