Partial after retries
The EEA/UK geographic HTTP 403 gate allowed a complete audit of the delivered notice but blocked the representative Yahoo News reading flow and normal robots/sitemap/indexing signals.
All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | Dark preference was active but color-scheme remained normal and the light palette did not retint. F-DARK medium: The notice ignores the user’s dark color-scheme preference. |
respect-user-preferencesrespects-reduced-motion | pass | high | The page has no scripts, no auto-advance, and getAnimations() returned an empty list under reduce. |
respect-user-preferencesrespects-contrast | pass | high | Text, links, rules, and focusable content remain visible in forced colors. |
implement-natural-interactionsview-transitions | not-applicable | high | The delivered geographic notice has no same-document state change or same-origin route transition to animate. |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | The notice has no scroll-linked animation, parallax, reveal, or scroll listener. |
implement-natural-interactionsphysical-gestures | pass | high | The page uses native document scrolling and ordinary anchors with no custom pointer handlers that fight platform gestures. |
provide-guided-navigationscroll-state-aware-chrome | not-applicable | high | The single static notice has no sticky or affixed chrome whose state needs to react to scrolling. |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip, popover, menu, or floating overlay exists on the delivered page. |
provide-guided-navigationdirects-attention | pass | high | Clear headings, blue link styling, descriptive Japanese service/help labels, and visible browser focus direct attention without in-page jumps. |
maximize-content-reduce-noiseno-intrusive-interruptions | pass | high | No popup, banner overlay, or interstitial obscures the notice. |
maximize-content-reduce-noisesemantic-dismissible-primitives | not-applicable | high | No disclosure, transient overlay, modal flow, custom select, or rich control is present. |
maximize-content-reduce-noisereduced-chrome | pass | high | The page is content-first with a compact brand header and simple cards; no app frame crowds the notice. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | pass | high | At 360 px the content reflows to one column; horizontalOverflowPx is 0 and viewport meta is present. |
adapt-to-the-form-factorcomponent-level-responsiveness | not-applicable | high | The notice has no reused component shown in independently sized containers; its single card context does not establish a container-query requirement. |
adapt-to-the-form-factorinput-modality-aware | issues | high | Multiple standalone links are only 14–24 px high; keyboard focus exists but is only the 1 px browser auto outline. F-INPUT-TARGETS medium: Touch targets are too short even though keyboard focus remains visible. |
support-core-task-successclear-purpose-and-primary-action | pass | high | The page immediately explains the EEA/UK restriction and presents available services and help links. |
support-core-task-successprimary-flow-completion | blocked | high | The audit host is in a restricted region: every news route returns the same HTTP 403 geographic notice, so the representative news-reading flow and normal templates cannot be exercised. |
support-core-task-successclear-system-state-and-recovery | pass | high | The restriction state is plainly stated in Japanese and English and provides alternative service and support links. |
be-fast-and-stablegood-core-web-vitals | issues | high | Lab LCP/FCP was 2885 ms, above the 2500 ms good threshold; CLS was low and TBT was zero. F-PERF medium: The small static notice misses the good LCP threshold in the captured load. |
be-fast-and-stablevisual-stability | pass | high | CLS measured 0.0159 desktop and 0 mobile, both in the good range. |
be-fast-and-stableefficient-main-thread | pass | high | The trace recorded no long tasks and 0 ms total blocking time. |
be-fast-and-stableefficient-resource-delivery | issues | high | Five ordinary parser-inserted stylesheet links are on the critical path; a 19 KB icon font is also fetched. F-RESOURCE-CHAIN low: Five parser-blocking stylesheets and an icon font delay a 99-element static document. |
be-fast-and-stabletrim-unused-and-duplicate-code | pass | high | No JavaScript is shipped and the complete transfer is only 73.7 KB; there is no evidence of a large duplicate or legacy bundle. |
be-inclusivenames-roles-labels | pass | high | The image has alt text, all 20 links have text names, and no invalid roles or unlabeled form controls were found. |
be-inclusivesufficient-contrast | issues | high | axe identifies 21 blue link nodes at 4.04:1 or 4.17:1, below the 4.5:1 WCAG AA minimum. F-CONTRAST high: Blue links do not meet WCAG AA contrast against white. |
be-inclusivestructure-and-focus | issues | high | There is no H1, the sequence starts H3 then H2, and contentinfo is nested inside main; focus itself remains visible. F-STRUCTURE medium: The document has no H1 and nests the contentinfo landmark inside main. |
be-inclusivelegible-text | pass | high | Body text reflows cleanly with comfortable line height and no clipping at desktop or 360 px. |
be-inclusivezoom-reflow-targets-and-media | issues | high | user-scalable=no disables zoom; many standalone links are 14–24 px high. F-MOBILE-A11Y high: Mobile zoom is disabled and many links have undersized activation areas. |
follow-best-practicesno-console-errors | pass | high | The delivered page contains no scripts or inline handlers, so there is no page JavaScript capable of throwing; no failed subresource appears in the HAR. |
follow-best-practicessound-document-and-assets | issues | high | Doctype and UTF-8 are valid, but the lone 1933 px PNG is displayed at 170 px and omits intrinsic height. F-ASSET low: The only image is oversized and lacks an intrinsic height. |
follow-best-practicesbrowser-platform-hygiene | pass | high | No scripts, deprecated API use, paste prevention, or load-time permission prompts were present on this notice. |
be-discoverabletitle-and-description | issues | high | The title is descriptive but meta description is absent. F-META medium: The notice has a descriptive title but no meta description. |
be-discoverablecrawlable-and-mobile-friendly | pass | high | All 20 links have real href values with visible text, the viewport declares device width, and the rendered page reflows without horizontal overflow. Zoom policy is recorded separately under inclusion. |
be-discoverablecanonical-and-indexing-signals | blocked | high | The current region receives HTTP 403 and the geographic notice for the homepage, robots.txt, sitemap.xml, and unknown paths, so normal indexing policy and sitemap consistency cannot be determined. |
be-discoverablestructured-and-shareable-metadata | issues | high | The dated notice contains zero Open Graph tags and zero JSON-LD blocks. F-SHARE low: The public notice exposes no share-preview or structured metadata. |
be-private-and-securesecure-transport-and-headers | issues | high | HTTPS is used and no cookies/mixed content were observed, but CSP, HSTS, and nosniff are absent. F-HEADERS high: The geographic-gate response omits several baseline browser security headers. |
be-private-and-securedata-minimisation-and-third-parties | pass | high | No cookies, known trackers, analytics calls, or exposed secrets were found; the only other origin is Yahoo’s static asset host. |
be-private-and-securein-context-permissions-and-modern-auth | not-applicable | high | The geographic notice has no permission request or authentication surface on which passkey support can be judged. |
be-private-and-securedefensive-browser-policies | issues | high | X-Frame-Options is present, but HSTS, CSP/frame-ancestors, Referrer-Policy, and Permissions-Policy are missing. F-HEADERS high: The geographic-gate response omits several baseline browser security headers. |
be-resilientprogressive-enhancement | pass | high | 100% of rendered content tokens are present in raw HTML; the page has no JavaScript shell. |
be-resilientresilient-runtime-behaviour | pass | high | The static page has no fragile async dependency, overlay, menu, or client state; content remains available without scripts. |
be-resilientoffline-and-installable | not-applicable | high | The delivered surface is a static access notice rather than an app; installability and an offline app shell are not proportionate requirements for this page. |
be-resilientnetwork-and-http-failure-states | pass | high | The server intentionally renders a complete explanatory notice with support links rather than a blank shell for the regional 403 state. |
be-internationalisedlang-dir-and-logical-properties | issues | high | The bilingual document has no html lang and no language marker on its English section. F-LANG high: The bilingual Japanese/English document does not declare its language. |
be-internationalisedlocale-aware-data | pass | high | The fixed publication dates are rendered in conventional Japanese and English forms in their respective content sections; there is no dynamic numeric/currency input. |
be-internationalisedtime-zone-correctness | not-applicable | high | The notice contains calendar dates but no event time, recurring interval, deadline, or cross-zone timestamp. |
be-trustworthyno-dark-patterns | pass | high | The restriction is explained directly, alternatives are clearly labeled, and there is no consent wall, upsell, disguised ad, or forced continuity. |
be-trustworthyhumane-error-handling | not-applicable | high | No form or editable input exists on the delivered notice. |
be-trustworthytrustworthy-input-assistance | not-applicable | high | No input exists on the delivered notice. |
be-trustworthysafe-commercial-and-account-flows | not-applicable | high | No checkout, subscription, consent, authentication, or account-management flow is exposed by this notice. |
be-sustainableoptimised-assets | issues | high | A 1933 px PNG is rendered at 170 px without responsive sources and accounts for 13 KB of the 73.7 KB page. F-SUSTAINABLE-IMAGE medium: The logo transfers far more source pixels than its rendered size needs. |
be-sustainableno-wasteful-work | pass | high | The page ships no JavaScript, performs only nine requests, and has no long tasks or background analytics. |
be-sustainablethird-party-and-media-budget | pass | high | There is no video/audio/autoplay or known tracker; total transfer is 73.7 KB and third-party traffic is limited to Yahoo static assets. |
be-agent-readystructured-agent-capabilities | not-applicable | high | The delivered notice exposes information and outbound links but no transactional capability for WebMCP or agentic tools; raw semantic content is already machine-readable. |
be-agent-readyon-device-inference | not-applicable | high | On-device inference would not improve this fixed, short access notice; no summarization or language-model workflow is needed. |
be-memory-efficientno-leak-under-repeated-interaction | not-applicable | high | The static, script-free notice has no representative stateful interaction to repeat ten times; synthetic scrolling would not test a real allocation lifecycle. |
be-memory-efficientbounded-footprint | pass | high | The steady-state heap summary is 1.92 MB self size with 44,072 snapshot nodes for a 99-element, script-free page, a proportionate footprint. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | No Detached* constructor appears among retained constructors, and the page has no scripts, inline handlers, timers, or client observers that can accumulate. |
