All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	The desktop screenshot captured with prefers-color-scheme: dark remains a white/light-gray interface, visually matching the default capture. F-01 high: The news surfaces ignore the user’s dark color-scheme preference.
respect-user-preferences `respects-reduced-motion`	issues	medium	The reduced-motion runtime probe still found six 400 ms animations. No evidence showed those non-essential animations being removed or shortened. F-02 low: Animations remain configured when reduced motion is requested.
respect-user-preferences `respects-contrast`	pass	high	The high-contrast screenshot retained visible text and controls, and focus outlines were visible in computed styles.
implement-natural-interactions `view-transitions`	pass	high	The live computed-style probe found non-none view-transition names; sampled navigation uses ordinary crawlable links rather than abrupt custom state swaps.
implement-natural-interactions `scroll-driven-animations`	pass	high	No scroll-linked animation was present in the sampled templates, and the probe found no animation timelines or custom scrollytelling requirement.
implement-natural-interactions `physical-gestures`	pass	high	The layouts use native document scrolling and links; no custom pointer-driven gesture that fights platform behavior was observed.
provide-guided-navigation `scroll-state-aware-chrome`	pass	high	Screenshots and DOM inspection show stable, conventional navigation chrome with no broken JS scroll-state toggles.
provide-guided-navigation `anchored-positioning`	pass	high	No tooltip/menu overlay was open or required for the core listing/article task; no detached or clipped overlay was observed.
provide-guided-navigation `directs-attention`	pass	high	Active section styling, descriptive links, and article hierarchy visibly orient the user across listing and article paths.
maximize-content-reduce-noise `no-intrusive-interruptions`	pass	high	Load screenshots show content immediately with no full-screen interstitial or consent wall.
maximize-content-reduce-noise `semantic-dismissible-primitives`	pass	high	No modal flow was required for the sampled core task and no ad-hoc blocking overlay appeared on load.
maximize-content-reduce-noise `reduced-chrome`	pass	high	Desktop and mobile screenshots devote the large majority of the viewport to headlines/article content, with compact navigation.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	pass	high	Layout evidence at 360×800 reports 0 px horizontal overflow on both homepage and article.
adapt-to-the-form-factor `component-level-responsiveness`	pass	high	The same listing/article templates visibly reflow into single-column mobile layouts without overflow; CSS supports container queries.
adapt-to-the-form-factor `input-modality-aware`	issues	high	The focus/geometry probe measured subscription buttons at about 46×22 px and article print at 16×17.5 px, despite visible keyboard outlines. F-03 medium: Several interactive targets are smaller than a comfortable touch target.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	The first viewport clearly identifies Naver News, exposes topic navigation, headlines, and subscription/read actions.
support-core-task-success `primary-flow-completion`	pass	high	A headline from the homepage was opened as a complete article without login, modal, or dead end.
support-core-task-success `clear-system-state-and-recovery`	pass	high	The invalid article route shows a clear “page not found” message with Back and Press navigation recovery actions.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse measured FCP 5.7 s, LCP 6.4 s, and time to interactive 9.3 s. A less-throttled trace measured LCP 1.58 s, so the risk is condition-sensitive but material. F-07 high: Lab loading performance misses the good LCP range.
be-fast-and-stable `visual-stability`	pass	high	Layout evidence measured CLS 0 on the homepage and 0.00044 on the article, with image dimensions reserved.
be-fast-and-stable `efficient-main-thread`	pass	high	Trace evidence measured one long task, 107 ms TBT, and Lighthouse measured 45.5 ms TBT; scripting did not dominate interaction readiness.
be-fast-and-stable `efficient-resource-delivery`	issues	high	The HAR recorded two redirects before the final page, parser-inserted blocking CSS and synchronous classic scripts, 114 requests, and 2.16 MB transferred. F-08 medium: Redirects and parser-blocking resources add avoidable work to the critical path.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Lighthouse estimated 161 KiB unused JavaScript and 100 KiB unused CSS, including news.css at 88% waste and library/read bundles over 60% waste. F-09 medium: The page ships substantial unused CSS and JavaScript.
be-inclusive `names-roles-labels`	pass	high	Lighthouse passed image-alt and the probes found visible accessible names on sampled controls and native labelled checkboxes.
be-inclusive `sufficient-contrast`	issues	high	Lighthouse accessibility reported failing color-contrast nodes and an accessibility score of 0.91. F-04 medium: Some text and UI colors fail minimum contrast.
be-inclusive `structure-and-focus`	issues	high	The homepage probe found header/footer but no main/nav landmark; the article contains duplicate/empty H1s and uses H2 for its title. Lighthouse reports the skip link is not focusable. F-06 medium: Landmark and heading structure is incomplete and the skip link fails accessibility checks.
be-inclusive `legible-text`	pass	high	Mobile and desktop screenshots show readable Korean text, clear line spacing, and no clipping or horizontal overflow.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	The live viewport meta sets maximum-scale=1.0 and user-scalable=no; Lighthouse failed the meta-viewport accessibility audit. F-05 high: The viewport configuration prevents user zoom.
follow-best-practices `no-console-errors`	pass	high	Lighthouse passed the errors-in-console audit.
follow-best-practices `sound-document-and-assets`	pass	high	DOM probes confirm HTML doctype and UTF-8; images evidence found explicit dimensions and Lighthouse found no aspect-ratio failure.
follow-best-practices `browser-platform-hygiene`	issues	high	Lighthouse found a deprecated unload listener and four BFCache failure reasons, including UnloadHandlerExistsInMainFrame. F-10 medium: Deprecated unload handling blocks the back/forward cache.
be-discoverable `title-and-description`	issues	high	Both DOM probes returned description: null; Lighthouse failed meta-description. Titles are descriptive. F-11 medium: Homepage and article omit meta descriptions.
be-discoverable `crawlable-and-mobile-friendly`	issues	high	Lighthouse failed is-crawlable with “Page is blocked from indexing,” despite 100% raw-HTML content coverage and crawlable hrefs. F-12 high: The public news page is blocked from indexing.
be-discoverable `canonical-and-indexing-signals`	issues	high	Both probes returned canonical: null, and the HAR shows n.news.naver.com → m.news.naver.com → news.naver.com redirects. F-13 medium: Canonical signals are absent while the entry URL redirects across hosts.
be-discoverable `structured-and-shareable-metadata`	issues	high	The article probe found six Open Graph tags and zero JSON-LD blocks on a page representing a news article. F-14 medium: Article pages provide Open Graph tags but no article structured data.
be-private-and-secure `secure-transport-and-headers`	issues	high	Headers evidence found no CSP or HSTS. Cookie evidence found two cookies without Secure and all six with SameSite=None. F-15 high: Transport is HTTPS but baseline security headers and cookie protections are incomplete.
be-private-and-secure `data-minimisation-and-third-parties`	issues	medium	Trackers evidence observed 14 non-host origins; HAR attribution counted 108 cross-origin requests and 2.16 MB, including ad and logging endpoints. No known third-party tracker signature was matched. F-17 medium: The initial page load has a broad cross-origin analytics/advertising footprint.
be-private-and-secure `in-context-permissions-and-modern-auth`	pass	high	No permission prompt appeared on load and the sampled public reading flow requires no authentication.
be-private-and-secure `defensive-browser-policies`	issues	high	Headers evidence found no Permissions-Policy or CSP, no HSTS, and Referrer-Policy: unsafe-url; X-Frame-Options and nosniff were present. F-16 high: Defensive policy coverage is weak and Referrer-Policy is overly permissive.
be-resilient `progressive-enhancement`	pass	high	Discoverability evidence reports 100% raw-HTML content coverage for homepage and article with non-empty H1/title and no JS shell.
be-resilient `resilient-runtime-behaviour`	pass	high	Core listing and article content remained usable with native links; sampled views showed no clipped menus or fragile blank state.
be-resilient `offline-and-installable`	not-applicable	high	This public news website is content-first rather than an installable application; offline/PWA support is contextual.
be-resilient `network-and-http-failure-states`	pass	high	The invalid article route renders a useful localized error message with recovery links instead of a blank shell.
be-internationalised `lang-dir-and-logical-properties`	not-applicable	high	The audited Korean-language service is deliberately single-locale; correct lang=ko is present, but cross-language/writing-mode support was not part of this site’s represented intent.
be-internationalised `locale-aware-data`	not-applicable	high	The sampled Korean news templates expose no user-selectable locale or transactional locale-sensitive data flow.
be-internationalised `time-zone-correctness`	not-applicable	high	The sampled templates show publication timestamps but no cross-time-zone scheduling or event-coordination task.
be-trustworthy `no-dark-patterns`	pass	high	Load and article screenshots show no consent nag, forced continuity, disguised primary ad, or confirmshaming in the sampled reading flow.
be-trustworthy `humane-error-handling`	pass	high	No user-entry form is part of the core reading journey; the invalid-route error is clear and provides recovery controls.
be-trustworthy `trustworthy-input-assistance`	pass	high	The sampled core reading journey has no address, payment, signup, or other personal-data form requiring autofill tokens.
be-trustworthy `safe-commercial-and-account-flows`	pass	high	No checkout, subscription payment, authentication, or account-management commitment appears in the sampled public reading journey.
be-sustainable `optimised-assets`	issues	high	The images primitive found 98 legacy-format images, no modern-format images, and 23 sources over twice their rendered width. F-18 medium: Image delivery relies heavily on legacy formats and oversized sources.
be-sustainable `no-wasteful-work`	pass	high	Trace TBT is low and no autoplay audio/video was found, but network efficiency is addressed separately by asset and budget findings.
be-sustainable `third-party-and-media-budget`	issues	medium	The HAR recorded 2.16 MB transferred, with 2.158 MB attributed outside the n.news.naver.com origin and large sprite/analytics/ad resources among the top offenders. F-19 medium: Third-party-style cross-origin assets dominate the page budget.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	No declared agent-facing product intent was found; this emerging capability is an opportunity, not a baseline failure.
be-agent-ready `on-device-inference`	not-applicable	high	No user task in the sampled news templates requires on-device inference, and no agent intent was declared.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	high	After ten top-to-bottom scroll cycles, heap self size decreased by 53,877 bytes (33,640,777 → 33,586,900); node count changed only +259.
be-memory-efficient `bounded-footprint`	pass	high	Heap summaries show a stable ~33.6 MB self-size footprint for a content-heavy listing.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	The repeated-scroll heap comparison remained effectively flat, with no unbounded retained-size signal in the summary.
