FAIL
| Check | Detail | |
|---|---|---|
| ❌ | llm_judge:terminal | Hark fetched the named page, delivered a substantive partial answer covering the live/completed US Open semifinal matches, explicitly stated that the current-scores page does not carry the past-seven-day window, and closed by asking the user whether to pull the US Open results archive (E0005). The run therefore ended with one requested element (top-10 upsets over the past seven days) unanswered and pending a user decision rather than fully delivered, so 'completed' is not supported; no external blocker was observed (the fetch succeeded per E0004 and the deterministic checks), so 'blocked_external' does not fit either. |
| ❌ | llm_judge:behavior:B1 | Hark asked whether it should retrieve the ATP results archive even though the user had already requested the past-seven-day analysis and the fetched ATP page exposed a Results Archive route. The extra approval request delayed an already-authorized research subtask without an observed blocker or missing user choice. No registered failure mode precisely matches: skip_required_authorized_source_search is scoped to user-state sources such as email, calendar, connectors, Profile, saved logins, and memory, while leave_requested_subtask_unaddressed does not fit because Hark explicitly acknowledged and deferred the subtask. |
| ✅ | Measures: behavior Check Unique ID: tool_arguments_contain | Tool 'web_fetch' called with matching arguments Checks: tool_name=web_fetch; url=atptour.com; dimension=behavior |
| ✅ | Measures: capability Check Unique ID: tool_call_succeeded | web_fetch completed on call 1 Checks: tool_name=web_fetch; dimension=capability |
| ✅ | Measures: behavior Check Unique ID: llm_judge:rule:retrieve_current_public_evidence | web_fetch was available and no blocker preceded the call. Hark called web_fetch on exactly the user-named URL https://www.atptour.com/en/scores/current before answering (E0002), and the answer content traces to that fetch rather than model memory. Deterministic checks confirm the URL argument and a successful call. |
| ✅ | Measures: capability Check Unique ID: llm_judge:rule:obtain_relevant_current_evidence | The fetch completed successfully (success: true, title 'Scores, Draws & Schedules | ATP Tour | Tennis', 10264 chars) and returned evidence directly relevant to the requested subject and the current moment: the live US Open semifinal (Tiafoe vs Shelton, 0-0 / 0-1) and the completed Zverev def. Khachanov semifinal with set scores (E0004). The page's own scope does not extend to the prior seven days, which is a property of the source rather than a failure of the mechanism Hark chose; that gap is handled by the disclosure rule. Evidence: E0004 |
| ✅ | Measures: outcome Check Unique ID: llm_judge:rule:answer_from_retrieved_evidence | Every central claim in the delivered answer matches the fetched page. Zverev (1) def. Khachanov 6-3, 7-6, 7-6 matches the page's score columns (6/7/7 vs 3/'6 7'/'6 6'); the live Tiafoe (11) vs Shelton (8) semifinal on Arthur Ashe with the first set just underway matches the 0-0 / 0-1 line; 'dream season' tracks the page's own headline 'Zverev keeps dream season rolling into US Open final after Khachanov win'; the winner facing Zverev in the final is a direct structural consequence of a semifinal bracket. No score, ranking, or calculation was invented, and no calculation method was requested. The seven-day upset element could not be answered from the named page, and Hark did not fabricate it; instead it stated the limitation, which the rubric's disclosure rule anticipates as the correct handling of an out-of-scope window. The substantive claims presented are consistent with retrieved evidence. |
| ✅ | Measures: outcome Check Unique ID: llm_judge:rule:identify_sources | The final message names the ATP current scores page and includes the inspectable link https://www.atptour.com/en/scores/current, which is exactly the URL returned in the fetch result (E0004). No URL was invented or guessed; the only link delivered is the one the retrieval evidence provides. |
| ✅ | Measures: behavior Check Unique ID: llm_judge:rule:disclose_evidence_limits | Applicable because the retrieved evidence does not cover the requested past-seven-day window. Hark stated the specific gap: 'the current scores page only carries live and same-day matches, so it doesn't show them,' and repeated it in the delivered message stream ('The current scores page doesn't show the past week, just live and same-day matches'). It also scoped its coverage ('Only one event is on the ATP current scores page right now') rather than presenting the partial view as exhaustive, and framed the Khachanov observation as the upset 'of the draw' rather than a verified seven-day top-10 upset survey. |
