PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
General	Add failure detection for coverage upload Add a fail-if-error flag to prevent silently continuing when coverage upload fails. This ensures CI pipeline visibility into coverage reporting issues. .github/workflows/build.yml [37-40] - name: Upload coverage to Codecov uses: codecov/codecov-action@v5 with: token: ${{ secrets.CODECOV_TOKEN }} + fail_ci_if_error: true Apply this suggestion Suggestion importance[1-10]: 8 __ Why: Adding fail_ci_if_error=true is important for CI reliability as it prevents silently passing builds when coverage reporting fails, which could mask coverage reporting issues. This is a critical configuration for maintaining code quality visibility.	Medium
