  "SUMMARY": "Cart element selector failure for negative test with invalid product",
  "NEEDS_REVIEW_DESCRIPTION": "This test is designed to verify that an invalid product 'IPHONE PRO' is not present in the cart, but it's failing while trying to locate the cart section element itself. The test appears to be a negative test case based on the 'INVALID-PRODUCT' parameter and expectation that 'IPHONE 13 PRO should not be found'. However, the failure occurs at the element location stage, not at the assertion stage. The triage report shows related cart tests are consistently failing with 100% failure rate, suggesting either a systemic cart page issue or a test implementation problem. The ambiguity arises from whether this is the expected behavior for an empty cart scenario versus a genuine page structure issue.",
  "IMPACT": "Without clarity on whether empty cart pages should have .cartSection h3 elements, teams cannot determine if this is a product defect requiring fixes or a test that needs refactoring for empty cart scenarios",
  "CONFIDENCE": 85,
  "ROOT_CAUSE": "The test expects to find a .cartSection h3 element to verify a product is NOT present, but the element itself cannot be located. This creates ambiguity: Is the cart genuinely empty (expected for invalid product), or is there a page loading/structure issue? The test's negative assertion logic may be flawed if it assumes cart elements exist even when empty. Evidence needed: cart page HTML when empty vs populated, test implementation logic for negative cases, and whether other cart tests are failing for the same selector issue.",
