Role Count Notes
Horticultural Technician 1 [#8] Responsible for weekly watering/inspection under the 30-minute exposure rule; incremental cost reflected in staff_wages.
Security Officer / MTF Agent 1 [#9] Incremental guard scheduling and one additional patrol checkpoint; cost reflected in staff_wages/security overhead.
📋 Confidence Notes
Analyst notes provide ranges and clear line items for all expected costs but many items are range-based and some optional (robotics, contingency reserve) making point estimates uncertain; confidence rated medium.
