Principle / checkStatusConfidenceEvidence or reason
respect-user-preferences
respects-color-scheme
issueshighDark 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-preferences
respects-reduced-motion
passhighThe page has no scripts, no auto-advance, and getAnimations() returned an empty list under reduce.
respect-user-preferences
respects-contrast
passhighText, links, rules, and focusable content remain visible in forced colors.
implement-natural-interactions
view-transitions
not-applicablehighThe delivered geographic notice has no same-document state change or same-origin route transition to animate.
implement-natural-interactions
scroll-driven-animations
not-applicablehighThe notice has no scroll-linked animation, parallax, reveal, or scroll listener.
implement-natural-interactions
physical-gestures
passhighThe page uses native document scrolling and ordinary anchors with no custom pointer handlers that fight platform gestures.
provide-guided-navigation
scroll-state-aware-chrome
not-applicablehighThe single static notice has no sticky or affixed chrome whose state needs to react to scrolling.
provide-guided-navigation
anchored-positioning
not-applicablehighNo tooltip, popover, menu, or floating overlay exists on the delivered page.
provide-guided-navigation
directs-attention
passhighClear headings, blue link styling, descriptive Japanese service/help labels, and visible browser focus direct attention without in-page jumps.
maximize-content-reduce-noise
no-intrusive-interruptions
passhighNo popup, banner overlay, or interstitial obscures the notice.
maximize-content-reduce-noise
semantic-dismissible-primitives
not-applicablehighNo disclosure, transient overlay, modal flow, custom select, or rich control is present.
maximize-content-reduce-noise
reduced-chrome
passhighThe page is content-first with a compact brand header and simple cards; no app frame crowds the notice.
adapt-to-the-form-factor
responsive-no-horizontal-scroll
passhighAt 360 px the content reflows to one column; horizontalOverflowPx is 0 and viewport meta is present.
adapt-to-the-form-factor
component-level-responsiveness
not-applicablehighThe 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-factor
input-modality-aware
issueshighMultiple 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-success
clear-purpose-and-primary-action
passhighThe page immediately explains the EEA/UK restriction and presents available services and help links.
support-core-task-success
primary-flow-completion
blockedhighThe 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-success
clear-system-state-and-recovery
passhighThe restriction state is plainly stated in Japanese and English and provides alternative service and support links.
be-fast-and-stable
good-core-web-vitals
issueshighLab 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-stable
visual-stability
passhighCLS measured 0.0159 desktop and 0 mobile, both in the good range.
be-fast-and-stable
efficient-main-thread
passhighThe trace recorded no long tasks and 0 ms total blocking time.
be-fast-and-stable
efficient-resource-delivery
issueshighFive 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-stable
trim-unused-and-duplicate-code
passhighNo JavaScript is shipped and the complete transfer is only 73.7 KB; there is no evidence of a large duplicate or legacy bundle.
be-inclusive
names-roles-labels
passhighThe image has alt text, all 20 links have text names, and no invalid roles or unlabeled form controls were found.
be-inclusive
sufficient-contrast
issueshighaxe 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-inclusive
structure-and-focus
issueshighThere 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-inclusive
legible-text
passhighBody text reflows cleanly with comfortable line height and no clipping at desktop or 360 px.
be-inclusive
zoom-reflow-targets-and-media
issueshighuser-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-practices
no-console-errors
passhighThe 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-practices
sound-document-and-assets
issueshighDoctype 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-practices
browser-platform-hygiene
passhighNo scripts, deprecated API use, paste prevention, or load-time permission prompts were present on this notice.
be-discoverable
title-and-description
issueshighThe title is descriptive but meta description is absent.
F-META medium: The notice has a descriptive title but no meta description.
be-discoverable
crawlable-and-mobile-friendly
passhighAll 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-discoverable
canonical-and-indexing-signals
blockedhighThe 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-discoverable
structured-and-shareable-metadata
issueshighThe 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-secure
secure-transport-and-headers
issueshighHTTPS 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-secure
data-minimisation-and-third-parties
passhighNo cookies, known trackers, analytics calls, or exposed secrets were found; the only other origin is Yahoo’s static asset host.
be-private-and-secure
in-context-permissions-and-modern-auth
not-applicablehighThe geographic notice has no permission request or authentication surface on which passkey support can be judged.
be-private-and-secure
defensive-browser-policies
issueshighX-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-resilient
progressive-enhancement
passhigh100% of rendered content tokens are present in raw HTML; the page has no JavaScript shell.
be-resilient
resilient-runtime-behaviour
passhighThe static page has no fragile async dependency, overlay, menu, or client state; content remains available without scripts.
be-resilient
offline-and-installable
not-applicablehighThe 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-resilient
network-and-http-failure-states
passhighThe server intentionally renders a complete explanatory notice with support links rather than a blank shell for the regional 403 state.
be-internationalised
lang-dir-and-logical-properties
issueshighThe 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-internationalised
locale-aware-data
passhighThe fixed publication dates are rendered in conventional Japanese and English forms in their respective content sections; there is no dynamic numeric/currency input.
be-internationalised
time-zone-correctness
not-applicablehighThe notice contains calendar dates but no event time, recurring interval, deadline, or cross-zone timestamp.
be-trustworthy
no-dark-patterns
passhighThe restriction is explained directly, alternatives are clearly labeled, and there is no consent wall, upsell, disguised ad, or forced continuity.
be-trustworthy
humane-error-handling
not-applicablehighNo form or editable input exists on the delivered notice.
be-trustworthy
trustworthy-input-assistance
not-applicablehighNo input exists on the delivered notice.
be-trustworthy
safe-commercial-and-account-flows
not-applicablehighNo checkout, subscription, consent, authentication, or account-management flow is exposed by this notice.
be-sustainable
optimised-assets
issueshighA 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-sustainable
no-wasteful-work
passhighThe page ships no JavaScript, performs only nine requests, and has no long tasks or background analytics.
be-sustainable
third-party-and-media-budget
passhighThere 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-ready
structured-agent-capabilities
not-applicablehighThe 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-ready
on-device-inference
not-applicablehighOn-device inference would not improve this fixed, short access notice; no summarization or language-model workflow is needed.
be-memory-efficient
no-leak-under-repeated-interaction
not-applicablehighThe static, script-free notice has no representative stateful interaction to repeat ten times; synthetic scrolling would not test a real allocation lifecycle.
be-memory-efficient
bounded-footprint
passhighThe 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-efficient
no-detached-dom-or-unbounded-listeners
passhighNo Detached* constructor appears among retained constructors, and the page has no scripts, inline handlers, timers, or client observers that can accumulate.
