📋 Confidence Notes
Analyst notes provide detailed line items and ranges, but many items have wide ranges (one-time engineering options, sovereign agreements, breadth of subterranean operations) and anomalous behavior increases uncertainty; medium confidence reflects detailed inputs but significant tails.
