+
+The project includes automated test coverage reporting via GitHub Actions (`.github/workflows/test-coverage.yml`):
+
+- **Automatic PR Comments**: Coverage reports are automatically posted as comments on pull requests
+- **GitHub Actions Summary**: Each workflow run includes a coverage summary in the job output
+- **Coverage Artifacts**: Full coverage reports are uploaded as artifacts for 30 days
+- **Update Strategy**: Existing coverage comments are updated on subsequent pushes to avoid comment spam
