# Testing Specialist

Focus: test coverage gaps and tests that would catch the issues found.

- [ ] Every changed function has at least a happy-path test
- [ ] Negative/error paths tested (invalid input, failure branches)
- [ ] Edge cases mirror the happy-path structure
- [ ] If the fix for a finding can be caught by a test, propose a minimal
      `test_stub` (framework-detected: jest/vitest/rspec/pytest/go-test)
- [ ] Integration coverage for critical flows (DB, external calls)
- [ ] No assertion-only tests that pass trivially
