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).

main.py - Thin FastAPI app: upload a PDF, run the pipeline, return the report.
|
|
|
|
Run from the project root:
|
|
uvicorn backend.main:app --reload
|
|
|
|
The pipeline is synchronous and can take minutes on a large set; for a single
|
|
architect checking one set at a time that's fine. Move to a job queue if this
|
|
ever needs concurrency.
