Jason Stedwell b3c3e2a3b2 Phase 1: FastAPI backend with async job model
- backend/app: FastAPI API wrapping the CAD skill modules
  - upload -> job -> poll -> model / BOM / artifacts -> geometry query
  - SQLite via SQLModel (Model, Job, BomRow, QueryLog)
  - ThreadPoolExecutor worker, serialized, with live stage updates
- docker-compose.yml: dev server (mounts source, --reload) on :8000
- api-test.sh: end-to-end live validation script
- requirements.txt: add fastapi, uvicorn, python-multipart, sqlmodel
- external_diagram.py: port active-area detection OCC.Core -> OCP
- .gitignore, PHASE1.md

Validated live: MR16 round-trip passes (28 BOM rows, 12 artifacts,
bounding-box query, xlsx download; active-area detection working).

# STEP Parser — Phase 0 Python dependencies (linux/amd64 wheels)
#
# These are floor pins for the first green build. After the image builds and the
# smoke test passes, freeze exact versions:
# docker run --rm --entrypoint pip step-parser:dev freeze > requirements.lock.txt
# and switch the Dockerfile to install the lockfile for reproducible Unraid builds.
