Runs a four-part QC pass on investment banking decks before they go to clients. It extracts numbers from every slide and checks consistency (same metric showing different values across slides, which happens more than it should), verifies that narrative claims match the actual data in charts, scans language for anything too casual or off-register for IB standards, and flags visual issues like missing source citations or inconsistent formatting. Works in both the PowerPoint add-in and chat. The number checking piece uses a script that normalizes units and catches conflicts you'd miss on the fifth read-through. Outputs a severity-ranked report so you know what blocks delivery versus what's just polish.
