What you get before you submit
One review built for verification—not a black-box score.
PlanPort organizes what it found into three practical views: what is in the package, where documents disagree, and which findings need a person to act.

Rule sources and authority
Maintain sources once. Keep their authority distinct.
Platform sources can be reused across projects, while municipality, project type, source status, and explicit project selections determine which configured records enter a review.
National model-code context remains separate from provincial and municipal authority.
