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).

However, the drawing index on G11.01 does not include a structural engineer or any S-series drawings for this tenant improvement project. This improperly transfers design liability to the contractor and creates a significant risk that the support cannot be built as detailed or that the existing structure cannot safely carry the unspecified load.

However, the drawings do not show the routing for these lines from the roof into the building, nor do they indicate a specific, coordinated termination point on the plumbing plans.
