📋 Confidence Notes
Estimates are midpoints of wide provided ranges; large uncertainties stem from negotiation outcomes with the Holy See/City of Rome, archaeological surprises during excavation, and the scale of required insurance/escrow for priceless frescoes. Recurring staffing/logistics estimates are better-defined but still variable.
