  "result": {
    "verdict": "FAILURE",
    "explanation": "The Web Task Instruction required finding hotels in London with specific criteria (price, duration, date, number of options). The Reference Answer indicates that these criteria were met. However, the Result Response explicitly states 'Task failed: page.evaluate: Execution context was destroyed, most likely because of a navigation'. This clearly indicates that the task was not completed, and therefore, none of the sub-components of the instruction were fulfilled. The Result Response does not align with the Reference Answer.",
    "agentAnswer": "Task failed: page.evaluate: Execution context was destroyed, most likely because of a navigation",
    "expectedAnswer": "hotel in London found with price under ~$250/night; 3+ hotel options found; duration 4 days confirmed; starts December 25",
    "failureClassification": "browser_crash",
    "classificationExplanation": "The browser's execution context was destroyed during navigation, indicated by the error 'Execution context was destroyed, most likely because of a navigation'. This, combined with very few events (11) and failure at the pre-action stage, suggests the browser process crashed or the tab closed unexpectedly before loading the page.",
