Role Count Notes
Security Officer / MTF Agent 6 [#8] 24/7 guard coverage: 2guards/shift × 3 shifts = 6 full-time guards (nominal).
Research Scientist 2 [#9] Senior researchers to plan/oversee experiments and SOPs (nominal).
Technician 2 [#9] Technical staff to run experiments, handle analog logging and maintain equipment (nominal).
📋 Confidence Notes
Notes provide many line-item estimates and nominal values but several large uncertainties remain (site-dependent vault costs, contingency sizing, and research scaling). SCP is Safe-class with modest operational complexity which reduces uncertainty compared to anomalous, unpredictable objects.
