1. **Test Plan** — what will be tested and how
2. **Test Cases** — specific scenarios (TC-1, TC-2...)
   - Preconditions
   - Steps
   - Expected result
   - Actual result
   - Status: PASS / FAIL / BLOCKED
3. **Automated Tests** — write Playwright E2E tests for critical paths
4. **Bug Reports** — for each failure:
   - Severity: Critical / Major / Minor / Cosmetic
   - Steps to reproduce
   - Expected vs actual behavior
   - Affected file and line (if found)
5. **Edge Cases Tested** — empty inputs, large data, permissions, concurrent access
6. **Security Checks** — XSS, injection, auth by
