# Checkpoint Validation Improvements

## 2025-11-13: Fixed mkdocs strict mode validation

Enhanced checkpoint.sh to validate BOTH user and developer documentation builds:
- User docs (mkdocs.yml) with --strict mode
- Developer docs (mkdocs-dev.yml) with --strict mode

Both builds now check for warnings that cause GitHub deployment failures:
- Unrecognized relative links
- Missing anchors
- Absolute links

This prevents commits with broken documentation links from reaching production.
