⚡ Cost Scenarios
📊 Baseline (baseline) $8.6M/yr
85.0% probability / year
Normal year with steady operations, routine maintenance, scheduled research and no major security incidents.
no breach routine maintenance scheduled research activity
🚨 Minor Incident $9.8M/yr
10.0% probability / year +$1.2M vs baseline
Limited containment incident or attempted theft requiring rapid-response deployment, short-term facility repairs, and increased PR/legal activity.
attempted theft or intrusion localized damage to access chamber or monitoring hardware limited contamination requiring remediation
🚨 Major Breach $18.6M/yr
5.0% probability / year +$10.0M vs baseline
Large-scale breach or loss of control of extradimensional space requiring reconstruction, major legal exposure, extended research interruption, and possible decommissioning actions.
successful large-scale incursion loss of containment requiring reconstruction public exposure/legal crisis
👥 Personnel 26 total
Role Count Notes
Security Officer / MTF Agent 10 [#4] 24/7 vault guards (8–12 guards covered in recurring security wage estimate #4).
Arborist / Horticulture Technician 9 [#7] Trained arborists and forestry technicians (6–12 specialists referenced in #7).
Research Scientist 7 [#9] Research personnel portion of recurring research budget (personnel included in #9 recurring costs).
📋 Confidence Notes
Analyst notes provide granular line-item ranges for most cost categories enabling mid-range estimates; uncertainty remains from anomalous behavior, political/exposure risk, and how many personnel are formally considered 'caretakers' (affecting clearance and rotation costs), so confidence is medium.
