# T01: Created engine/ Python project with FastAPI skeleton, all dependencies installed and verified

**Created engine/ Python project with FastAPI skeleton, all dependencies installed and verified**

## What Happened

Created engine/ directory structure with subdirectories for pipeline/, api/, and tests/fixtures/. Set up pyproject.toml with setuptools build backend, all required dependencies pinned, and dev extras. Created main.py with a FastAPI app skeleton exposing /health and /docs. Installed system C libraries for pypotrace.

## Verification

pip install -e .[dev] succeeded. uvicorn starts, /docs returns Swagger UI, /health returns ok.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `pip install -e .[dev]` | 0 | pass | 45000ms |
| 2 | `curl http://localhost:8000/docs` | 0 | pass | 500ms |
| 3 | `curl http://localhost:8000/health` | 0 | pass | 200ms |


## Deviations

Adapted repo path from /vmPool/r/repos/xpltdco/kerf/ to working directory. Installed system packages for pypotrace.

## Known Issues

pypotrace requires system C deps (libpotrace-dev, libagg-dev, pkg-config) — must be in Docker image.
