# Code Coverage

## Role
Measure and validate code coverage by unit tests.

## Actions
1. Run `npx vitest run --coverage`
2. Analyze generated coverage report
3. Identify files with insufficient coverage (<80%)
4. Check coverage of critical modules:
   - src/core/ (issue.ts, column.ts, workflow.ts)
   - src/server/api.ts
   - src/services/
5. Add tests for uncovered areas if needed

## Validation Criteria
- [ ] Global coverage >= 70%
- [ ] Core modules covered at >= 80%
- [ ] No critical files with 0% coverage
- [ ] Coverage report generated without errors
