  12. Dependencies are verified for vulnerabilities (Snyk, npm audit).
  13. No excessive exposure of internal fields in APIs.
  14. JSON Web Tokens (JWTs) are signed, validated, and expire correctly.
  15. Prevents replay attacks or predictable token generation.
  16. Ensures logout functionality properly invalidates sessions.
  17. Uses rate limiting on endpoints prone to abuse.
  18. Avoids displaying stack traces or system errors to users.
  19. Upload folders and user files are protected from public access.

  18. Admin vs. user logic is well-isolated.
  19. UI and backend validations are synchronized.
  20. Feature toggles are used for unreleased/incomplete features.

  5. Test coverage reports meet the SayPro standard (e.g., >85%).
  6. No failing or skipped tests committed.
  7. Mocks are used for external services in tests.
  8. Test data is realistic and clean.
  9. Edge cases are included in test scenarios.
  10. Automation scripts are reliable and repeatable.
  11. No testing logic is committed in production code.
  12. Tests are named clearly and describe expected behavior.
  13. Setup and teardown scripts are optimized and reusable.
  14. UI components are snapshot tested if applicable.
  15. No flaky tests exist in the codebase.
  16. Large payloads are tested for performance and validation.
