    "benchmark_issue_note": "The instruction, visual target, and success trigger appear aligned; human and all agent modes completed the task.",
    "cross_run_summary": "This task was solved cleanly in every provided run. The three browsergym modes matched the human in a single direct click on the day cell for February 5, 2026, while browser_use took a longer but still straightforward path with navigation, wait, click, and explicit done. No run shows confusion about the calendar idiom, target location, or post-click state.",
    "primary_task_story": "The task is a low-difficulty check of whether agents can ground a simple date-selection instruction onto a visible embedded calendar when the correct month is already open. Its diagnostic value comes mainly from comparing observation modes: all of them were sufficient for direct date targeting, suggesting the component exposes the day cell clearly in DOM, accessibility tree, and pixels.",
    "keep_revise_expand_retire_hint": "retire",
    "keep_revise_reason": "Because all modes and frameworks succeeded immediately or near-immediately, the task offers little separation on grounding or interaction competence beyond confirming basic calendar clicking.",

The target date was already visible in the initially loaded February 2026 grid, the instruction exactly matched the UI copy, and the completion signal appeared immediately after selecting the correct day. Across ax_tree, som, and pixel, the agent could identify and click the same date cell in one step; browser_use only added framework overhead before making the same effective selection.",
