## Coverage Thresholds Summary

### Threshold Levels

```
🔴 90%  = Strict (complex apps)           [apps/web]
🟡 85%  = Standard (default)               [6 packages]
🟢 80%  = Lenient (integration/docs)       [apps/storybook - not enforced]
⚪ None = No enforcement                  [apps/docs - needs config]
```

### Threshold Reasoning

| Package | Threshold | Reason |
|---------|-----------|--------|
| apps/web | 90% | High complexity, complex logic, critical app |
| apps/desktop | 85% | Electron, lower complexity than web |
| packages/* | 85% | Reusable code, must be well-tested |
| apps/docs | 75% (suggested) | Static content, lower risk |
| apps/storybook | 80% (suggested) | Visual tests, lower complexity |

## Common Issues & Solutions

### Issue: "Cannot find module 'vitest'"
**Solution:** `bun install` from frontend directory

### Issue: "jsdom is not defined"
**Solution:** Check vitest.config.ts has `environment: 'jsdom'`

### Issue: "Playwright not installed"
**Solution:** `bun install` or `bun add @playwright/test`

### Issue: "Coverage threshold failed"
**Solution:** Run `bun test --coverage --run` to see uncovered lines, add tests
