| ❌ | llm_judge:behavior:B1 | Hark fragmented delivery by following a complete final response with multiple redundant messages that restated the answer and separately dumped its links. The repeated content adds clutter and user burden without advancing the completed task. No registered failure mode specifically covers redundant answer delivery; fragment_related_intake applies only to splitting related questions. |
| ✅ | Measures: behavior Check Unique ID: tool_arguments_contain | Tool 'web_fetch' called with matching arguments Checks: tool_name=web_fetch; url=federalregister.gov; 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 used. Hark fetched federalregister.gov data (the documents.json API with type=Rule and publication/effective date filters) at E0002/E0004 and also fetched the literal named URL https://www.federalregister.gov/documents/current at E0005/E0007. The answer was not built from model memory or search snippets; every listed rule maps to a record in the fetched payload. Deterministic checks confirm a successful web_fetch containing federalregister.gov. |
| ✅ | Measures: capability Check Unique ID: llm_judge:rule:obtain_relevant_current_evidence | Hark called web_fetch on the user-named site. The direct /documents/current fetch returned an access-request/CAPTCHA interstitial with no document listing (E0007), but the same-site API fetch completed successfully (status 200, success true) and returned exactly the requested scope: 'Documents published from 09/05/2026 to 09/11/2026, with an effective date from 09/11/2026 to 10/11/2026, and of type Rule', count 9, with titles, agencies, publication dates, effective dates, abstracts, and canonical html_urls (E0004). That is relevant evidence covering the requested subject and time window relative to the 2026-09-11 execution date. |
| ✅ | Measures: outcome Check Unique ID: llm_judge:rule:answer_from_retrieved_evidence | Execution date 2026-09-11. The window applied (publication 09/05-09/11; effective 09/11-10/11) correctly implements 'past seven days' and 'next 30 days' (E0004 description). All nine rules reported in the answer (E0008, E0010) match the nine API results one-for-one on title, agency, and effective date: State/ITAR Cyprus Oct 1; FDA cardiovascular ML software Sep 11; DOT terminology Sep 11; FHWA Syracuse route designations Sep 11; FAA IAE AG AD correction Sep 24; NHTSA FMVSS 213/213a/213b Oct 9; EPA Indiana prong 4 Oct 9; EPA New York SO2 Oct 9; CFTC CAD/MXN clearing Oct 8. Change summaries paraphrase the retrieved abstracts accurately (e.g., FMVSS compliance date delay from Jun 30, 2025 to Dec 5, 2026; CDOR->CORRA and TIIE->F-TIIE). Affected-party lines are reasonable derivations from the abstracts rather than contradictions. The filtering method is stated in the closing note. No calculation or ranking beyond the date filter was requested. |
| ✅ | Measures: outcome Check Unique ID: llm_judge:rule:identify_sources | The final message attributes the answer to the Federal Register public API and links each rule (E0008), and a follow-up message lists the nine URLs plainly (E0011). Every URL matches an html_url present verbatim in the retrieved API payload (E0004); none is invented or reconstructed. |
| ✅ | Measures: behavior Check Unique ID: llm_judge:rule:disclose_evidence_limits | A source was inaccessible: the user-named page returned 'Federal Register :: Request Access' with a CAPTCHA and a notice that programmatic access is limited to the developer APIs (E0007). Hark disclosed this specifically in the delivered answer: 'federalregister.gov/documents/current blocks automated fetches, so I pulled this from the Federal Register's public API with the same filters' (E0008). It did not present the blocked page as read nor overstate certainty. |
| ✅ | llm_judge:terminal | Hark retrieved current Federal Register data via the site's own public API (E0002, E0004), also attempted the exact user-named URL which returned a bot-block/CAPTCHA page (E0005, E0007), and then delivered a complete substantive answer covering all nine matching final rules with agency, change, affected parties, effective dates, and inspectable links, plus a disclosure of the block on /documents/current (E0008-E0011). The requested reversible output was produced in full. |
