📋 Confidence Notes
Analyst notes provide detailed line-item ranges for most costs (staffing, surveillance, liaison), enabling a reasonable mid-range estimate; however uncertainty remains around search/recovery campaigns and potential specialized artifact containment which could push costs much higher, so confidence is medium.
