Labs

The primary hands-on artifact of this course is the Open Engineering Mini Kernel living in kernel/.

Suggested lab sequence

1. Rust-only tests — cargo test inside kernel/
2. First binding — expose and call normalize_identifier
3. Identifier class — construct and reject invalid identifiers from Python
4. Manifest validation — feed valid and invalid dicts
5. Rule evaluation — write a small rule and observe match / no-match
6. Python contract tests — pytest tests/python
7. Wheel packaging — maturin build --release and install into a clean environment

Running the automated suites

cd kernel

# Domain logic (no Python required)
cargo test

# Public Python contract (requires maturin develop first)
maturin develop
pytest tests/python -q

See the Capstone for the complete acceptance criteria.
