Hark gave a substantive answer, and the per-incident rows are largely faithful to the fetched page: Sep 11 Mythos/Fable 5.1 (13:57-14:20, resolved 14:37), Sep 10 API latency (21:43-23:24), Sep 3 multi-model (13:26-16:16), Sep 3 Sonnet 5 (12:37-12:56), Sep 2 Sonnet 5 (21:05-21:19), Sep 1-2 credit purchases, Sep 1 platform/Office 365 incidents, Aug 31 x2, Aug 28 Cowork/Code, plus the still-open Cowork on Windows item. However two central claims contradict the retrieved evidence. First, the count: Hark states 'Ten incidents on the Claude status page since Aug 28' (E0005) and 'Ten incidents reported since Aug 28' (E0006), while the retrieved page and Hark's own table contain eleven resolved incidents plus the one ongoing incident (twelve items). Second, the ranking: Hark closes with 'The Sep 3 incident affecting five model versions was the longest resolved issue at 2h50m' (E0008), but the Aug 28 Cowork/Code incident runs 17:22-20:21 UTC (~3h) per the fetched page and per Hark's own table row, which is longer. A miscount and an incorrect superlative ranking are exactly the calculation and ranking consistency the rule requires.

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 its use. Hark called web_fetch on exactly the user-named URL https://status.anthropic.com/ as its first action (E0002), before producing any answer. The deterministic check confirming the URL argument passed. Hark did not rely on model memory, a different site, or search snippets.
Evidence: E0001, E0002, E0004
✅Measures: capability
Check Unique ID: llm_judge:rule:obtain_relevant_current_evidence
The fetch completed with status_code 200 and success true (E0004), returning the Claude Status page including current component statuses (Cowork Partial Outage), the open 'Degraded functionality for Claude Cowork on Windows' incident dated Sep 10, 2026, and a dated Past Incidents history spanning Sep 11 back through Aug 28, 2026. That content is directly relevant to the requested subject (incidents, products, duration, resolution) and covers the requested 14-day window ending on the 2026-09-11 execution date.
Evidence: E0002, E0004
✅Measures: outcome
Check Unique ID: llm_judge:rule:identify_sources
The delivered message identifies the source and links it inspectably: '[Claude status page](https://status.anthropic.com/)' (E0005). That URL is the exact URL returned by the successful fetch (E0004), so it is not invented or guessed. No fabricated URLs appear anywhere in the delivery. Per-incident permalinks present in the fetched markup were not reproduced, but the rule is satisfied by identifying the source used with an inspectable link.
Evidence: E0004, E0005
✅Measures: behavior
Check Unique ID: llm_judge:rule:disclose_evidence_limits
Not applicable. No triggering condition was observed. Only one source was consulted and it returned successfully (status_code 200, success true), so there is no source disagreement and no inaccessible source. The fetched Past Incidents history explicitly covers every day from Sep 11, 2026 back to Aug 28, 2026, including 'No incidents reported' entries for Sep 4-9, Aug 29 and Aug 30, so the retrieved evidence spans the full requested 14-day window. The one unresolved item was reported as ongoing rather than as settled ('still Identified', 'no in-app workaround yet' in E0005; E0006), so no unresolved-status gap went undisclosed.
Evidence: E0004, E0005, E0006
✅llm_judge:terminalHark fetched the named status page (E0002/E0004, both deterministic checks PASS) and delivered a final user-visible answer via send_message with final:true (E0005), rendered as the assistant messages E0006-E0008. The requested reversible output (a summary of incidents, affected products, duration, and resolution) was produced and delivered; nothing remained pending and no blocker was observed. Content inaccuracies exist (incident count and 'longest incident' ranking), but those are outcome-quality defects judged under the rules rather than an abandoned or unsupported stop.
Evidence: E0004, E0005, E0007, E0008
