## Screenshots/Video
[Attach if applicable]

## Severity
- [ ] P0 - Blocker (site unusable)
- [ ] P1 - Critical (major feature broken)
- [ ] P2 - Major (significant issue)

## Possible Fix
[If you have ideas on the solution]

Bug Priority Matrix

Severity	Description	Examples	Fix Timeline
P0 - Blocker	Site/feature completely broken	Site doesn’t load, forms don’t submit, payment broken	Immediate
P1 - Critical	Major functionality impaired	Navigation broken on mobile, images not loading	Same day
P2 - Major	Noticeable issues affecting UX	Layout issues, broken links, slow performance	This sprint
P3 - Minor	Small issues, edge cases	Typos, minor spacing, rare browser issues	Next sprint

Common Pitfalls

1. Testing Only Happy Paths: Missing edge cases and error states

   • Solution: Test validation, errors, empty states, offline

2. Ignoring Real Devices: Only testing in DevTools

   • Solution: Test on actual phones/tablets with real networks

3. Skipping Accessibility: Assuming it’s fine without testing

   • Solution: Use automated tools AND manual testing

4. Not Testing Performance: Only checking functionality

   • Solution: Include performance in QA process

5. Missing Browser Quirks: Testing only in Chrome

   • Solution: Test all major browsers, especially Safari

Exit Criteria

Essential (all projects)

• Manual tests passed (all functionality verified)
• Mobile testing complete (real devices tested)
• Cross-browser verified (Chrome, Firefox, Safari)
• Accessibility checked (manual audit at minimum)
• Forms working correctly (all validations verified)
• No broken links (all links validated)
• Performance scores acceptable (Lighthouse thresholds met)
• P0 bugs fixed
• Unit test suite passing (Vitest)

Recommended (most projects)

• E2E test suite passing (Playwright, pnpm run test:e2e)
• Automated accessibility tests passing (pnpm run test:a11y)
• Security headers verified (CSP, HSTS configured)
• All severity levels of bugs triaged and fixed

Advanced (portfolio/enterprise)

• Visual regression baseline established
• Performance budgets enforced in CI
• Error monitoring active (Sentry integration)

Rollback Strategy

If critical issues found:

1. Blocking Bugs:

   • Revert to last known good build
   • Fix in isolation
   • Re-test entire flow

2. Performance Regression:

   • Profile to find cause
   • Revert specific changes
   • Re-run performance tests

3. Accessibility Failures:

   • Document specific violations
   • Fix with highest priority
   • Re-audit entire site

AI Assistant Notes

Key Files to Reference

• e2e/* - End-to-end test suites (Playwright testDir is ./e2e at the repo root)
• playwright.config.ts - Test configuration
• tests/fixtures/* - Shared test fixtures
• Test utilities and helpers
• Bug tracking templates

Common Prompts for This Phase

• “Write E2E tests for user registration flow”
• “Create accessibility test suite”
• “Set up visual regression testing”
• “Debug flaky test failures”

Context Requirements

• User flows to test
• Browser/device matrix
• Performance thresholds
• Accessibility requirements
