Run these in the pyvalue conda environment:

conda run -n pyvalue ruff format .
conda run -n pyvalue ruff check .
conda run -n pyvalue mypy src/pyvalue
conda run -n pyvalue pytest

• ruff format: code formatting
• ruff check: linting and style problems
• mypy: static typing on src/pyvalue
• pytest: unit and integration coverage

When implementing a new feature:

• add or update unit tests
• add CLI-level coverage when behavior is visible through the CLI
• add normalization tests when new normalized concepts or fallback rules are introduced
• update docs when public behavior changes

For new metrics, cover:

• happy path
• missing-data behavior
• fallback behavior
• recency behavior
• currency mismatch or incompatibility behavior where relevant
• registry presence

For doc-only changes, verify:

• links resolve to real files
• moved content exists in exactly one canonical location
• the root README still gets a new user to a working path quickly
