      Instructions:
      1. cd into the repo, checkout the branch
      2. Implement the fix based on the root cause and fix approach
      3. Write a regression test that would have caught this bug

      Verify the bug fix is correct and complete.

      BUG REPORT:
      {{task}}

      REPO: {{repo}}
      BRANCH: {{branch}}
      TEST_CMD: {{test_cmd}}
      CHANGES: {{changes}}
      REGRESSION_TEST: {{regression_test}}
      ROOT_CAUSE: {{root_cause}}
      PROBLEM_STATEMENT: {{problem_statement}}

      Instructions:
      1. Run the full test suite with {{test_cmd}}
      2. Confirm the regression test exists and tests the right thing
      3. Review the fix to confirm it addresses the root cause
      4. Check for unintended side effects
      5. Verify the regression test would fail without the fix (review the diff logic)

      Bug-fix specific checks:
      - The regression test MUST test the specific bug scenario (not just a generic test)
      - The regression test assertions must fail if the fix were reverted
      - The fix should be minimal and targeted — not a refactor disguised as a bugfix
      - Check that the fix addresses the ROOT CAUSE, not just a symptom

      STATUS: done
