Evidence Center features
The mechanics behind the headline.
Bidirectional links
Composite indexes on each side so forward and reverse evidence questions answer in one hop.
Manual prompts for complicated equipment
Rooftop units, switchgear, elevators get a 'upload the manual' prompt so the takeoff carries the right accessories.
Reviewable AI claims
Low-confidence claims enter a queue; estimators confirm, correct, or reject — and the symbol library learns.
