Package examples

The repository contains executable examples, not merely snippets:

• Minimal MCF 1.1 course
• MCF 1.1 feature showcase
• Calculus I reference course
• Standalone module, lesson, question bank, and asset collection
• MCF 1.0 compatibility fixtures

Run python3 scripts/check_conformance.py PATH from a repository checkout to validate a directory package or .mcf.zip archive with the reference runner.
