- Its example flags a 168 m² arithmetic discrepancy and a 0.60 m height mismatch across dossier documents.
Field notes
The walkthrough follows a dossier through extraction, recalculation, and source citation; each figure is associated with a document and page. The fictional example includes a mismatch between a form and building description, while the project’s own test reports three discrepancies in 11 dossiers across eight procedures. The page says plans are outside the tool’s scope and that reviewers retain the decision.
