All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	The dark screenshot is pixel-equivalent to the light capture; the dark-mode probe reports html background rgb(255,255,255), color-scheme normal, and no color-scheme CSS signal. F001 medium: The page ignores the user’s dark color-scheme preference.
respect-user-preferences `respects-reduced-motion`	pass	high	The preference probe confirms reduce is active, with zero document animations and scroll-behavior auto.
respect-user-preferences `respects-contrast`	issues	high	The platform probe finds no prefers-contrast or forced-colors CSS; axe reports link contrast ratios of 4.04–4.17:1 where 4.5:1 is required. F002 medium: The page has no high-contrast adaptation and some essential links remain below WCAG contrast minimums.
implement-natural-interactions `view-transitions`	not-applicable	high	Not applicable to the static regional restriction surface.
implement-natural-interactions `scroll-driven-animations`	pass	high	The static page has no scroll-linked motion, no animations, and no animation-timeline/scroll-timeline CSS, so it does not misuse main-thread scroll handlers.
implement-natural-interactions `physical-gestures`	pass	high	The notice has no custom pointer gesture handlers or gesture UI and relies on native document scrolling; no conflicting gesture behavior was observed.
provide-guided-navigation `scroll-state-aware-chrome`	pass	high	The page has no sticky or affixed navigation chrome that needs scroll-state adaptation; content scrolls as one continuous document without obstruction.
provide-guided-navigation `anchored-positioning`	not-applicable	high	Not applicable to the static regional restriction surface.
provide-guided-navigation `directs-attention`	pass	high	The single-page notice uses clear article cards and link styling; in-page navigation does not move focus or scroll to hidden destinations.
maximize-content-reduce-noise `no-intrusive-interruptions`	pass	high	The load screenshot shows content immediately with no popup/interstitial; the platform probe reports zero dialogs and zero custom overlays.
maximize-content-reduce-noise `semantic-dismissible-primitives`	pass	high	No transient overlay or disclosure control is present, so there is no ad-hoc div-based control replacing a semantic primitive.
maximize-content-reduce-noise `reduced-chrome`	pass	high	The notice devotes nearly the entire viewport to its availability message, with only a compact logo header and footer.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	pass	high	At 360x800, scrollWidth, clientWidth, and innerWidth are all 360px; horizontalOverflowPx is 0 and viewport meta is present.
adapt-to-the-form-factor `component-level-responsiveness`	not-applicable	high	Not applicable to the static regional restriction surface.
adapt-to-the-form-factor `input-modality-aware`	issues	high	At 360px, the target-size probe measures several primary links at 16–21px tall and footer links at 14px tall; keyboard focus itself remains visible. F003 high: Many mobile link targets are substantially shorter than the recommended touch target.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	The first viewport clearly states that Yahoo! JAPAN is unavailable in the EEA/UK and the body explains the decision and available alternatives.
support-core-task-success `primary-flow-completion`	pass	high	For the delivered restriction state, the complete flow is reading the notice and following available-service/help links; all 20 links have real href destinations and no modal/account detours.
support-core-task-success `clear-system-state-and-recovery`	pass	high	The HTTP 403 state is rendered as a clear bilingual explanation with help and still-available service links instead of a blank shell or spinner.
be-fast-and-stable `good-core-web-vitals`	issues	high	The trace summary reports LCP 2549.39ms, about 49ms beyond the 2.5s good threshold; CLS is only 0.001 and TBT is 13.15ms. F004 low: Observed LCP narrowly misses the good threshold in this test.
be-fast-and-stable `visual-stability`	pass	high	Observed CLS is 0 on mobile and 0.001068 on desktop, with only one negligible shift.
be-fast-and-stable `efficient-main-thread`	pass	high	The trace records one 63.15ms long task and only 13.15ms total blocking time; the page ships no JavaScript.
be-fast-and-stable `efficient-resource-delivery`	issues	high	The HAR summary identifies five render-blocking stylesheet candidates, all confirmed in the rendered DOM; FCP and LCP occur together at 2549.39ms. F005 medium: Five parser-inserted external stylesheets delay first rendering.
be-fast-and-stable `trim-unused-and-duplicate-code`	pass	high	The page ships no JavaScript, only 73,729 transferred bytes over 9 requests, and no third-party tracker code; no large duplicate/legacy bundle is present.
be-inclusive `names-roles-labels`	pass	high	The single image has meaningful alt text, links have text names, and axe reports no accessible-name, role, or image-alt violation.
be-inclusive `sufficient-contrast`	issues	high	axe-core reports 21 affected link nodes at 4.04–4.17:1 against white, below the required 4.5:1 for their sizes and weights. F006 high: Essential links fail WCAG AA text contrast.
be-inclusive `structure-and-focus`	issues	high	The document starts with H3 then H2 elements and has no H1; axe also reports that the contentinfo footer is nested inside main. Focus indication on links is present. F007 medium: The heading and landmark hierarchy is malformed.
be-inclusive `legible-text`	pass	high	Body text reflows without clipping at 360px, uses readable spacing, and remains stable; no media or canvas text is present.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	The viewport is width=device-width,user-scalable=no; axe classifies this as a critical accessibility violation. Narrow reflow itself has no horizontal overflow. F008 high: Mobile pinch zoom is explicitly disabled.
follow-best-practices `no-console-errors`	pass	high	The delivered document contains no script elements or event-driven application runtime, and all evidence primitives loaded it without a Runtime exception. Lighthouse could not score the intentional 403 response.
follow-best-practices `sound-document-and-assets`	issues	high	The image audit reports a 1933px-wide PNG rendered at 170px, with a width attribute but no height attribute. F009 medium: The logo lacks an intrinsic height and is massively oversized for its rendered slot.
follow-best-practices `browser-platform-hygiene`	pass	high	The static page invokes no deprecated APIs, permissions, notifications, geolocation, paste handlers, or vulnerable client library; it ships no JavaScript.
be-discoverable `title-and-description`	issues	high	DOM and discoverability probes find the title in raw HTML but no meta[name=description]. F010 medium: The page has a descriptive title but no meta description.
be-discoverable `crawlable-and-mobile-friendly`	issues	high	The DOM contains multiple links labelled only “here”; /robots.txt returns the same HTTP 403 restriction document instead of robots text. All anchors do have real href values. F011 low: Some link text is non-descriptive and crawler control endpoints are not available from this region.
be-discoverable `canonical-and-indexing-signals`	pass	high	The delivered state consistently returns HTTP 403 for the root, robots, sitemap, and unknown paths, matching its explicit regional-denial purpose rather than accidentally exposing an indexable success page.
be-discoverable `structured-and-shareable-metadata`	not-applicable	high	Not applicable to the static regional restriction surface.
be-private-and-secure `secure-transport-and-headers`	issues	high	The headers primitive finds no Content-Security-Policy, Strict-Transport-Security, or X-Content-Type-Options; there are no cookies or mixed-content signals. F012 high: The HTTPS response lacks baseline security headers.
be-private-and-secure `data-minimisation-and-third-parties`	pass	high	No cookies, known trackers, analytics calls, or exposed secrets were found. The sole third-party origin is Yahoo’s static asset CDN s.yimg.jp.
be-private-and-secure `in-context-permissions-and-modern-auth`	not-applicable	high	Not applicable to the static regional restriction surface.
be-private-and-secure `defensive-browser-policies`	issues	high	X-Frame-Options is SAMEORIGIN, but Referrer-Policy and Permissions-Policy are missing and no CSP frame-ancestors policy is present. F013 medium: Several browser-enforced defensive policies are absent.
be-resilient `progressive-enhancement`	pass	high	Discoverability reports 100% raw-to-rendered content coverage and no JS shell; the crawler screenshot retains the complete notice.
be-resilient `resilient-runtime-behaviour`	pass	high	The page has no runtime application state, overlays, async dependencies, or scripts; its static links and content remain visible without JavaScript.
be-resilient `offline-and-installable`	not-applicable	high	Not applicable to the static regional restriction surface.
be-resilient `network-and-http-failure-states`	pass	high	The main 403 and unknown-path 403 responses show the same useful bilingual availability explanation and recovery links rather than a broken shell.
be-internationalised `lang-dir-and-logical-properties`	issues	high	The html element has neither lang nor dir; axe reports html-has-lang, while the platform probe finds no logical inline/block properties. F014 high: The bilingual document has no language metadata and no logical-property CSS signal.
be-internationalised `locale-aware-data`	pass	high	The static notice presents its date in conventional Japanese and English forms within separately authored language sections and contains no currencies, quantities, durations, or user-locale calculations.
be-internationalised `time-zone-correctness`	not-applicable	high	Not applicable to the static regional restriction surface.
be-trustworthy `no-dark-patterns`	pass	high	The notice states the restriction directly, shows alternatives, has no consent wall, upsell, disguised advertising, preselected choice, or forced continuity.
be-trustworthy `humane-error-handling`	not-applicable	high	Not applicable to the static regional restriction surface.
be-trustworthy `trustworthy-input-assistance`	not-applicable	high	Not applicable to the static regional restriction surface.
be-trustworthy `safe-commercial-and-account-flows`	not-applicable	high	Not applicable to the static regional restriction surface.
be-sustainable `optimised-assets`	issues	high	The image audit reports a 1933px source displayed at 170px, no srcset, and PNG format; it transfers 13,017 bytes. F015 low: The only content image wastes pixels and uses a legacy PNG without responsive alternatives.
be-sustainable `no-wasteful-work`	pass	high	There is no JavaScript, background processing, analytics, polling, or over-fetch loop; load uses 9 requests and 73,729 transferred bytes.
be-sustainable `third-party-and-media-budget`	pass	high	No video/audio/autoplay exists, no tracker was detected, and the only third-party is Yahoo’s asset CDN; total transfer is 73,729 bytes.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	Not applicable to the static regional restriction surface.
be-agent-ready `on-device-inference`	not-applicable	high	Not applicable to the static regional restriction surface.
be-memory-efficient `no-leak-under-repeated-interaction`	not-applicable	high	Not applicable to the static regional restriction surface.
be-memory-efficient `bounded-footprint`	pass	high	The static 99-element document uses about 0.96MB JS heap at runtime; the heap summary is 1.92MB self size with 44,087 nodes, proportionate for Chrome’s baseline environment.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	The baseline heap top constructors contain no Detached* population; the page has no scripts, timers, observers, or application listeners to accumulate.
