+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

+Output JSON lines:
