Generator Feature Dashboard

This dashboard shows which LinkML metamodel features each generator supports. The compliance test suite (tests/linkml/test_compliance/) is the source of truth — every cell below is derived from actual test results.

Regenerate with: uv run pytest tests/linkml/test_compliance/ --with-output && uv run python scripts/generate_dashboard.py
