Cross-discipline design-contradiction checker for construction drawing sets. Standalone tool broken out from Iron_Bid; a pipeline stage may later fold back into Iron_Bid. Pipeline: PDF->images -> per-sheet assertion extraction -> deterministic clustering by location -> per-cluster reasoning -> report. Includes CLI (cli/run_check.py) and web UI (backend/main.py).
