All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	Desktop screenshots under default and prefers-color-scheme: dark are pixel-identical; the page remains a bright white surface. F001 medium: The portal does not adapt to the user’s dark color preference.
respect-user-preferences `respects-reduced-motion`	issues	high	The reduced-motion probe matched the preference but found three 7,000 ms animations and no reduced-motion CSS rules. F002 medium: Long animations continue when reduced motion is requested.
respect-user-preferences `respects-contrast`	issues	high	Lighthouse’s axe-backed color-contrast audit failed; its overall accessibility score was 0.74. F003 high: Text and controls include insufficient color contrast.
implement-natural-interactions `view-transitions`	issues	high	DOM/CSS inspection found no view-transition, animation-timeline, scroll-timeline, scroll-snap, or container-query support on the interaction-heavy portal. F004 low: Route, tab, scroll, and drawer interactions use legacy state changes rather than modern natural-interaction affordances.
implement-natural-interactions `scroll-driven-animations`	issues	high	DOM/CSS inspection found no view-transition, animation-timeline, scroll-timeline, scroll-snap, or container-query support on the interaction-heavy portal. F004 low: Route, tab, scroll, and drawer interactions use legacy state changes rather than modern natural-interaction affordances.
implement-natural-interactions `physical-gestures`	issues	high	DOM/CSS inspection found no view-transition, animation-timeline, scroll-timeline, scroll-snap, or container-query support on the interaction-heavy portal. F004 low: Route, tab, scroll, and drawer interactions use legacy state changes rather than modern natural-interaction affordances.
provide-guided-navigation `scroll-state-aware-chrome`	pass	high	Search-result CSS includes a fixed search state on scroll and the screenshots preserve clear global/category navigation.
provide-guided-navigation `anchored-positioning`	issues	high	The probe found 13 custom modal-class elements but zero dialog or popover elements; CSS implements fixed overlays and manual visibility. F005 medium: Overlays and menus are custom div-based implementations rather than semantic top-layer primitives.
provide-guided-navigation `directs-attention`	pass	high	Selected tabs use persistent underline/color states and article/search screenshots maintain clear section cues.
maximize-content-reduce-noise `no-intrusive-interruptions`	issues	high	Desktop and 360×800 screenshots show a large pink reward modal and backdrop blocking search, news, and navigation before user interaction. F006 high: A promotional reward interstitial obscures the primary portal content on load.
maximize-content-reduce-noise `semantic-dismissible-primitives`	issues	high	The probe found 13 custom modal-class elements but zero dialog or popover elements; CSS implements fixed overlays and manual visibility. F005 medium: Overlays and menus are custom div-based implementations rather than semantic top-layer primitives.
maximize-content-reduce-noise `reduced-chrome`	issues	high	Desktop and 360×800 screenshots show a large pink reward modal and backdrop blocking search, news, and navigation before user interaction. F006 high: A promotional reward interstitial obscures the primary portal content on load.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	issues	high	At a 360×800 capture, the article renders a dense multi-column desktop page scaled into the viewport, with very small text; its viewport declaration is only width=device-width. F007 high: The article template does not present a mobile-first layout at a narrow viewport.
adapt-to-the-form-factor `component-level-responsiveness`	issues	high	At a 360×800 capture, the article renders a dense multi-column desktop page scaled into the viewport, with very small text; its viewport declaration is only width=device-width. F007 high: The article template does not present a mobile-first layout at a narrow viewport.
adapt-to-the-form-factor `input-modality-aware`	issues	high	Lighthouse failed button-name, image-alt, link-name, and accessibility-tree audits. The focus probe found many early anchors with outline:none, and the home probe found multiple empty H1 elements and unlabeled search inputs. F008 high: Accessible names, semantic structure, and keyboard focus are unreliable.
support-core-task-success `clear-purpose-and-primary-action`	issues	high	Desktop and 360×800 screenshots show a large pink reward modal and backdrop blocking search, news, and navigation before user interaction. F006 high: A promotional reward interstitial obscures the primary portal content on load.
support-core-task-success `primary-flow-completion`	pass	high	The direct search-results path loaded 1,000 of 2,569 matching news results with query continuity and sorting controls.
support-core-task-success `clear-system-state-and-recovery`	pass	high	The search template contains explicit empty/error states and /sitemap.xml’s 404 page explains the failure and links back to dmenu TOP.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse performance was 0.03 with FCP 9.1 s, LCP 18.3 s, TBT 2,210 ms and CLS 0.921. The raw-CDP trace corroborated FCP 10.79 s, LCP 12.46 s, TBT 318.55 ms and a 320.79 ms longest task; layout measured CLS 0.43 mobile and 0.61 desktop. F009 critical: The entry page is extremely slow and unstable.
be-fast-and-stable `visual-stability`	issues	high	The image primitive found all 100 images missing explicit dimensions, 55 below-fold images without lazy loading, 40 oversized images, 44 legacy-format images, and 42 missing alt text. F011 high: Image markup wastes bytes and contributes to instability and accessibility gaps.
be-fast-and-stable `efficient-main-thread`	issues	high	Lighthouse performance was 0.03 with FCP 9.1 s, LCP 18.3 s, TBT 2,210 ms and CLS 0.921. The raw-CDP trace corroborated FCP 10.79 s, LCP 12.46 s, TBT 318.55 ms and a 320.79 ms longest task; layout measured CLS 0.43 mobile and 0.61 desktop. F009 critical: The entry page is extremely slow and unstable.
be-fast-and-stable `efficient-resource-delivery`	issues	high	HAR recorded 137 requests and 3.20 MB transferred, including 49 scripts (2.55 MB) and 2.05 MB third-party bytes. Confirmed head scripts top_index_libs7.js and top_index_com.js have neither async nor defer; cache and compression gaps are also present. F010 high: The page ships excessive, poorly prioritized script and third-party work.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	HAR recorded 137 requests and 3.20 MB transferred, including 49 scripts (2.55 MB) and 2.05 MB third-party bytes. Confirmed head scripts top_index_libs7.js and top_index_com.js have neither async nor defer; cache and compression gaps are also present. F010 high: The page ships excessive, poorly prioritized script and third-party work.
be-inclusive `names-roles-labels`	issues	high	Lighthouse failed button-name, image-alt, link-name, and accessibility-tree audits. The focus probe found many early anchors with outline:none, and the home probe found multiple empty H1 elements and unlabeled search inputs. F008 high: Accessible names, semantic structure, and keyboard focus are unreliable.
be-inclusive `sufficient-contrast`	issues	high	Lighthouse’s axe-backed color-contrast audit failed; its overall accessibility score was 0.74. F003 high: Text and controls include insufficient color contrast.
be-inclusive `structure-and-focus`	issues	high	Lighthouse failed button-name, image-alt, link-name, and accessibility-tree audits. The focus probe found many early anchors with outline:none, and the home probe found multiple empty H1 elements and unlabeled search inputs. F008 high: Accessible names, semantic structure, and keyboard focus are unreliable.
be-inclusive `legible-text`	issues	high	At a 360×800 capture, the article renders a dense multi-column desktop page scaled into the viewport, with very small text; its viewport declaration is only width=device-width. F007 high: The article template does not present a mobile-first layout at a narrow viewport.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	Home, services, and search templates set maximum-scale=1 and user-scalable=no; Lighthouse failed meta-viewport. The article screenshot also shows tiny scaled desktop text at 360 px. F012 high: The portal disables user zoom and has weak narrow-screen reflow.
follow-best-practices `no-console-errors`	issues	high	Lighthouse failed errors-in-console, deprecations (4 warnings), inspector-issues, bfcache, and valid-source-maps. HAR also recorded ORB-blocked scripts. F013 medium: The page logs runtime/platform errors and uses deprecated or recovery-hostile patterns.
follow-best-practices `sound-document-and-assets`	issues	high	The image primitive found all 100 images missing explicit dimensions, 55 below-fold images without lazy loading, 40 oversized images, 44 legacy-format images, and 42 missing alt text. F011 high: Image markup wastes bytes and contributes to instability and accessibility gaps.
follow-best-practices `browser-platform-hygiene`	issues	high	Lighthouse failed errors-in-console, deprecations (4 warnings), inspector-issues, bfcache, and valid-source-maps. HAR also recorded ORB-blocked scripts. F013 medium: The page logs runtime/platform errors and uses deprecated or recovery-hostile patterns.
be-discoverable `title-and-description`	pass	high	All four representative pages expose specific non-empty titles and descriptions; the article description matches visible content.
be-discoverable `crawlable-and-mobile-friendly`	issues	high	Lighthouse failed crawlable-anchors and canonical audits. Recon found javascript:void(0) and HTTP links; /sitemap.xml returns 404; the home OG URL is HTTP; no JSON-LD is present. The no-JS crawler view exposes navigation but omits the main dynamic news content. F014 medium: Crawler and indexing signals are incomplete or inconsistent.
be-discoverable `canonical-and-indexing-signals`	issues	high	Lighthouse failed crawlable-anchors and canonical audits. Recon found javascript:void(0) and HTTP links; /sitemap.xml returns 404; the home OG URL is HTTP; no JSON-LD is present. The no-JS crawler view exposes navigation but omits the main dynamic news content. F014 medium: Crawler and indexing signals are incomplete or inconsistent.
be-discoverable `structured-and-shareable-metadata`	issues	high	Lighthouse failed crawlable-anchors and canonical audits. Recon found javascript:void(0) and HTTP links; /sitemap.xml returns 404; the home OG URL is HTTP; no JSON-LD is present. The no-JS crawler view exposes navigation but omits the main dynamic news content. F014 medium: Crawler and indexing signals are incomplete or inconsistent.
be-private-and-secure `secure-transport-and-headers`	issues	high	Headers primitive found no CSP, HSTS, Referrer-Policy, or Permissions-Policy. Cookie audit found 11 cookies reported without Secure, including a session-named cookie, and several 400-day identifiers; all use SameSite=None. F015 high: Defensive response headers and cookie protections are incomplete.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	Tracker capture found 22 third-party origins and 10 known tracker domains, including DoubleClick, Taboola, Criteo, Google Analytics and Google Ads. HAR attributes 59 requests and 2.05 MB to third parties. F016 high: The portal has a broad advertising and tracking footprint before user interaction.
be-private-and-secure `in-context-permissions-and-modern-auth`	pass	high	No permission prompt fired on load; account/auth destinations remain user-initiated links outside the content path.
be-private-and-secure `defensive-browser-policies`	issues	high	Headers primitive found no CSP, HSTS, Referrer-Policy, or Permissions-Policy. Cookie audit found 11 cookies reported without Secure, including a session-named cookie, and several 400-day identifiers; all use SameSite=None. F015 high: Defensive response headers and cookie protections are incomplete.
be-resilient `progressive-enhancement`	issues	high	The crawler screenshot with scripting disabled displays a warning to enable JavaScript and leaves the primary news/content region empty, while the rendered screenshot contains a large feed. F017 high: Primary portal content depends on JavaScript.
be-resilient `resilient-runtime-behaviour`	pass	high	Representative home, listing, search, and article routes all rendered usable states despite several blocked third-party requests.
be-resilient `offline-and-installable`	not-applicable	high	The audited public portal is not presented as an installable application; offline installation was judged outside this run’s core browsing intent.
be-resilient `network-and-http-failure-states`	pass	high	The observed 404 response provides a Japanese error explanation, likely causes, and a route back to dmenu TOP.
be-internationalised `lang-dir-and-logical-properties`	pass	high	All representative pages declare html lang=ja; sampled layouts rendered Japanese text correctly.
be-internationalised `locale-aware-data`	not-applicable	high	The sampled service is explicitly Japanese and exposed no user-selectable locale or locale-sensitive input flow.
be-internationalised `time-zone-correctness`	not-applicable	high	No scheduling, event coordination, or user-entered time-zone-sensitive flow was present on the representative paths.
be-trustworthy `no-dark-patterns`	issues	high	Desktop and 360×800 screenshots show a large pink reward modal and backdrop blocking search, news, and navigation before user interaction. F006 high: A promotional reward interstitial obscures the primary portal content on load.
be-trustworthy `humane-error-handling`	pass	high	The observed error page explains what happened without blame and offers a clear recovery link; search CSS defines explicit empty/error messaging.
be-trustworthy `trustworthy-input-assistance`	issues	high	Home and search probes show search inputs with autocomplete=off and no associated label or aria-label; Lighthouse also reports naming failures. F018 medium: Search fields suppress browser input assistance and lack explicit labels.
be-trustworthy `safe-commercial-and-account-flows`	not-applicable	high	No checkout, subscription, cancellation, or authenticated account flow was entered in the unauthenticated representative scope.
be-sustainable `optimised-assets`	issues	high	The image primitive found all 100 images missing explicit dimensions, 55 below-fold images without lazy loading, 40 oversized images, 44 legacy-format images, and 42 missing alt text. F011 high: Image markup wastes bytes and contributes to instability and accessibility gaps.
be-sustainable `no-wasteful-work`	issues	high	The 3.20 MB load spends 2.05 MB on third parties, while image inspection found 44 legacy images, 40 oversized images, and 55 below-fold images loaded eagerly. F019 high: Third-party scripts and inefficient assets create a disproportionate transfer and processing budget.
be-sustainable `third-party-and-media-budget`	issues	high	The 3.20 MB load spends 2.05 MB on third parties, while image inspection found 44 legacy images, 40 oversized images, and 55 below-fold images loaded eagerly. F019 high: Third-party scripts and inefficient assets create a disproportionate transfer and processing budget.
be-agent-ready `structured-agent-capabilities`	issues	high	DOM/source inspection found ordinary forms but no WebMCP or agentic tool registration; the public portal has actionable search and service-discovery surfaces. F020 low: The portal’s search and service actions are not exposed as structured agent capabilities.
be-agent-ready `on-device-inference`	not-applicable	high	The portal exposes no summarization or generative feature whose inference placement can be assessed.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	medium	After ten drawer open/close cycles, heap self size rose 1.6% (37.06 MB to 37.66 MB), DOM node count stayed 1,466, and closures stayed effectively flat (37,811 to 37,813); no clear retained-growth leak signal.
be-memory-efficient `bounded-footprint`	pass	medium	Heap summary measured 37.06 MB baseline self size and 37.66 MB post-interaction for a script-heavy portal; large but bounded across the sampled interaction.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	medium	The repeated drawer probe left the live DOM count unchanged at 1,466 and heap summaries showed no Detached constructor among top retained constructors.
