Description

Tests run in CI but coverage is never measured or reported. Without a baseline it is impossible to tell if PRs are eroding test coverage.

What Needs to Happen

• Add --coverage to backend Vitest config, output lcov, upload to Codecov
• Run cargo tarpaulin on contracts and upload XML to Codecov
• Set minimum thresholds: 60% backend, 70% contracts — fail CI if below
• Add coverage badge to README
• Codecov PR comments showing diff coverage

Files

• .github/workflows/
• backend/vitest.config.ts
• README.md

Acceptance Criteria

• Coverage badge on README
• CI fails if coverage drops below thresholds
• Codecov PR comments appear
