All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	The dark-mode screenshot is pixel-for-pixel equivalent in palette to the light capture; the body remains white and the notice panel remains light peach. F01 medium: The service notice ignores the user’s dark color-scheme preference.
respect-user-preferences `respects-reduced-motion`	pass	high	Reduced-motion emulation reports zero animations and zero transitions, so no unavoidable motion is present.
respect-user-preferences `respects-contrast`	issues	high	Lighthouse/axe reports both red #ff0000 spans on white at 3.99:1, below the required 4.5:1 for 16px normal text. F02 high: Important red status and recovery text fails WCAG AA contrast.
implement-natural-interactions `view-transitions`	not-applicable	high	No applicable surface was present.
implement-natural-interactions `scroll-driven-animations`	not-applicable	high	No applicable surface was present.
implement-natural-interactions `physical-gestures`	pass	high	The notice uses native anchors for pointer/touch activation and has no custom pointer handlers, gesture traps, or scroll interference.
provide-guided-navigation `scroll-state-aware-chrome`	not-applicable	high	No applicable surface was present.
provide-guided-navigation `anchored-positioning`	not-applicable	high	No applicable surface was present.
provide-guided-navigation `directs-attention`	pass	high	Desktop screenshot clearly prioritises the red out-of-hours status and bordered schedule panel immediately after the “お知らせ” heading.
maximize-content-reduce-noise `no-intrusive-interruptions`	pass	high	Initial screenshot and DOM show content directly, with no overlay or interstitial.
maximize-content-reduce-noise `semantic-dismissible-primitives`	not-applicable	high	No applicable surface was present.
maximize-content-reduce-noise `reduced-chrome`	pass	high	The viewport is almost entirely status content and links, with only a compact branded header/footer.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	issues	high	At a 360x800 device viewport, layout reports clientWidth 980 and visual scale 0.367 because no viewport meta exists; the screenshot shows tiny text and controls. F03 high: The page has no mobile viewport and is rendered as a 980px desktop canvas scaled down to 360px.
adapt-to-the-form-factor `component-level-responsiveness`	issues	high	At a 360x800 device viewport, layout reports clientWidth 980 and visual scale 0.367 because no viewport meta exists; the screenshot shows tiny text and controls. F03 high: The page has no mobile viewport and is rendered as a 980px desktop canvas scaled down to 360px.
adapt-to-the-form-factor `input-modality-aware`	issues	high	At a 360x800 device viewport, layout reports clientWidth 980 and visual scale 0.367 because no viewport meta exists; the screenshot shows tiny text and controls. F03 high: The page has no mobile viewport and is rendered as a 980px desktop canvas scaled down to 360px.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	The title, “お知らせ” heading, red status line, and schedule make the current purpose explicit.
support-core-task-success `primary-flow-completion`	not-applicable	high	No applicable surface was present.
support-core-task-success `clear-system-state-and-recovery`	pass	high	The page names the out-of-hours state, gives exact opening times, and links to troubleshooting when shown during reception hours.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse records LCP 2.6s and a 740ms root response; HAR records the document at 2297ms and all three images missing cache headers despite only 15KB total transfer. F04 medium: A tiny static notice is delayed by document latency and uncached assets.
be-fast-and-stable `visual-stability`	pass	high	Mobile layout observation records CLS 0 with no shift entries.
be-fast-and-stable `efficient-main-thread`	pass	high	Trace records zero long tasks and 0ms total blocking time; the page has no scripts.
be-fast-and-stable `efficient-resource-delivery`	issues	high	Lighthouse records LCP 2.6s and a 740ms root response; HAR records the document at 2297ms and all three images missing cache headers despite only 15KB total transfer. F04 medium: A tiny static notice is delayed by document latency and uncached assets.
be-fast-and-stable `trim-unused-and-duplicate-code`	pass	high	DOM probe finds zero scripts and HAR contains only one document plus three images/favicon, with no duplicate JS/CSS payload.
be-inclusive `names-roles-labels`	pass	high	Both images have non-empty alt text and all eight anchors have accessible text; Lighthouse did not report name/role failures.
be-inclusive `sufficient-contrast`	issues	high	Lighthouse/axe reports both red #ff0000 spans on white at 3.99:1, below the required 4.5:1 for 16px normal text. F02 high: Important red status and recovery text fails WCAG AA contrast.
be-inclusive `structure-and-focus`	issues	high	The DOM probe finds no header/nav/main/aside/footer landmarks, and Lighthouse reports landmark-one-main failure on the html element. F05 medium: The document has no main landmark.
be-inclusive `legible-text`	issues	high	At a 360x800 device viewport, layout reports clientWidth 980 and visual scale 0.367 because no viewport meta exists; the screenshot shows tiny text and controls. F03 high: The page has no mobile viewport and is rendered as a 980px desktop canvas scaled down to 360px.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	At a 360x800 device viewport, layout reports clientWidth 980 and visual scale 0.367 because no viewport meta exists; the screenshot shows tiny text and controls. F03 high: The page has no mobile viewport and is rendered as a 980px desktop canvas scaled down to 360px.
follow-best-practices `no-console-errors`	pass	high	The script-free page completed Lighthouse and CDP evaluation without an uncaught runtime/console error audit.
follow-best-practices `sound-document-and-assets`	issues	high	The active DOM reports doctype null and compatMode BackCompat; Lighthouse’s doctype audit fails. F06 medium: The response omits an HTML doctype and renders in quirks mode.
follow-best-practices `browser-platform-hygiene`	issues	high	Direct HTTP probes show /robots.txt, /sitemap.xml, /manifest.webmanifest, and /nonexistent-audit-probe all return 200 text/html with the same notice; Lighthouse also reports bfcache disabled by no-store. F07 medium: Every tested utility and nonexistent path returns the out-of-service HTML with HTTP 200.
be-discoverable `title-and-description`	issues	high	The DOM probe reports description null and Lighthouse’s meta-description audit fails, although the title is present. F08 medium: The page has no meta description.
be-discoverable `crawlable-and-mobile-friendly`	issues	high	At a 360x800 device viewport, layout reports clientWidth 980 and visual scale 0.367 because no viewport meta exists; the screenshot shows tiny text and controls. The DOM probe lists seven of eight anchors with identical text “こちら”, obscuring destination and purpose when scanned or read out of context. F03 high: The page has no mobile viewport and is rendered as a 980px desktop canvas scaled down to 360px. F09 medium: Most links use the repeated generic label “こちら” (“here”).
be-discoverable `canonical-and-indexing-signals`	issues	high	/robots.txt and /sitemap.xml return the service notice as 200 text/html; Lighthouse reports 83 robots.txt errors, and the DOM has no canonical URL. F10 high: Indexing endpoints and canonical signals are malformed or absent.
be-discoverable `structured-and-shareable-metadata`	issues	high	The DOM probe finds zero JSON-LD blocks and zero Open Graph properties. F11 low: The public service notice has no structured or social-preview metadata.
be-private-and-secure `secure-transport-and-headers`	issues	high	The headers primitive reports no CSP, HSTS, X-Content-Type-Options, X-Frame-Options/frame-ancestors, Referrer-Policy, or Permissions-Policy. F12 high: HTTPS is used, but all audited defensive response headers are absent.
be-private-and-secure `data-minimisation-and-third-parties`	pass	high	HAR/trackers/cookies report zero third-party origins, zero trackers, and zero cookies; secrets scan finds no exposed credential.
be-private-and-secure `in-context-permissions-and-modern-auth`	not-applicable	high	No applicable surface was present.
be-private-and-secure `defensive-browser-policies`	issues	high	The headers primitive reports no CSP, HSTS, X-Content-Type-Options, X-Frame-Options/frame-ancestors, Referrer-Policy, or Permissions-Policy. F12 high: HTTPS is used, but all audited defensive response headers are absent.
be-resilient `progressive-enhancement`	pass	high	Discoverability comparison reports 100% visible content without JavaScript and isJsShell false.
be-resilient `resilient-runtime-behaviour`	pass	high	The page uses no scripts, asynchronous UI, menus, or overlays; its visible notice is available directly in server HTML.
be-resilient `offline-and-installable`	not-applicable	high	No applicable surface was present.
be-resilient `network-and-http-failure-states`	issues	high	Direct HTTP probes show /robots.txt, /sitemap.xml, /manifest.webmanifest, and /nonexistent-audit-probe all return 200 text/html with the same notice; Lighthouse also reports bfcache disabled by no-store. F07 medium: Every tested utility and nonexistent path returns the out-of-service HTML with HTTP 200.
be-internationalised `lang-dir-and-logical-properties`	pass	high	The document declares html lang="ja" and the Japanese-only LTR notice renders coherently.
be-internationalised `locale-aware-data`	pass	high	All visible dates, weekdays, and times are presented consistently in Japanese notation for the site’s Japanese audience.
be-internationalised `time-zone-correctness`	pass	high	The static schedule uses explicit local clock times and weekday labels without client-side Date conversion or ambiguous offset math.
be-trustworthy `no-dark-patterns`	pass	high	The status page contains no consent, upsell, disguised control, forced action, or preselected choice.
be-trustworthy `humane-error-handling`	pass	high	The unavailable state is explained in plain language with schedules and a troubleshooting link rather than blame or a dead end.
be-trustworthy `trustworthy-input-assistance`	not-applicable	high	No applicable surface was present.
be-trustworthy `safe-commercial-and-account-flows`	not-applicable	high	No applicable surface was present.
be-sustainable `optimised-assets`	issues	high	The images primitive finds two legacy PNG images, no modern formats, and no srcset for the larger logo; Lighthouse flags low-resolution responsive image delivery. F13 low: Small decorative raster assets lack modern/resolution-aware variants.
be-sustainable `no-wasteful-work`	pass	high	HAR shows five small first-party requests and the trace shows no long tasks; there is no script or background processing.
be-sustainable `third-party-and-media-budget`	pass	high	HAR totals 14,987 transferred bytes with zero third-party bytes, fonts, audio, or video.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	No applicable surface was present.
be-agent-ready `on-device-inference`	not-applicable	high	No applicable surface was present.
be-memory-efficient `no-leak-under-repeated-interaction`	not-applicable	high	No applicable surface was present.
be-memory-efficient `bounded-footprint`	pass	high	Heap summary is proportionate for this static page: 27,563 nodes/heap records and 863,948 bytes self size, with no application framework.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	The single-state heap summary contains no Detached* constructor among reported populations, and the page has zero scripts that could register accumulating listeners/timers.
