All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	The dark-mode screenshot remains a light #f6f8fc surface; ui-probe reports prefers-color-scheme: dark matched while root color-scheme is normal and body text remains dark on a light background. F01 medium: The news experience ignores the requested dark colour scheme.
respect-user-preferences `respects-reduced-motion`	pass	high	prefers-reduced-motion matched and document.getAnimations() returned no active animations.
respect-user-preferences `respects-contrast`	pass	high	Forced-colours mode preserves readable text, controls and boundaries; Lighthouse color-contrast scored 1.
implement-natural-interactions `view-transitions`	issues	high	DOM and stylesheet inspection across home, topic and story templates found no view-transition declarations or named transition elements. F19 low: Template changes use abrupt full-state swaps rather than declarative view transitions.
implement-natural-interactions `scroll-driven-animations`	pass	high	No scroll-linked visual effect is present, and no animation-timeline or active animation was found, so the feed does not implement a main-thread scroll-animation anti-pattern.
implement-natural-interactions `physical-gestures`	pass	high	The feed uses native document scrolling and ordinary links/buttons; no custom swipe, drag or pointer-driven interaction was present in the representative reading flow.
provide-guided-navigation `scroll-state-aware-chrome`	issues	high	The 6,591 px home capture and 26,590 px topic DOM show very long listings, while DOM/CSS inspection found no scroll-state query, scroll progress indicator or adaptive header state. F20 low: The long feed offers no scroll-state progress or adaptive chrome.
provide-guided-navigation `anchored-positioning`	pass	high	No tooltip or detached floating menu is required for the primary signed-out reading flow; visible controls remain attached and unclipped in the captured states.
provide-guided-navigation `directs-attention`	pass	high	Descriptive topic links, story titles, section headings and See more headlines controls provide clear orientation from home to topic and story overview.
maximize-content-reduce-noise `no-intrusive-interruptions`	issues	high	Navigating to https://news.google.com redirects to consent.google.com and replaces the feed with a full-page Before you continue decision surface. F02 high: A full-page consent interstitial blocks the requested news content on first visit.
maximize-content-reduce-noise `semantic-dismissible-primitives`	pass	high	The consent choice uses native buttons with explicit Reject all and Accept all actions; the news reading surfaces do not introduce custom modal divs in the exercised path.
maximize-content-reduce-noise `reduced-chrome`	pass	high	The home, topic and story templates devote the main viewport to headlines and source context; application chrome is compact relative to the long content feed.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	issues	high	The mobile layout primitive reports visualViewportWidth 360, scrollWidth 1024 and horizontalOverflowPx 664; the full-page capture is 1024 px wide. F03 high: The layout exposes a desktop-width canvas in a 360 px visual viewport.
adapt-to-the-form-factor `component-level-responsiveness`	issues	high	Computed styles on home, topic and story report container-type normal, and the captured CSS contains no @container rules; the narrow-viewport run falls back to a 1024 px layout. F21 medium: Reusable feed cards do not expose container-driven responsive behaviour.
adapt-to-the-form-factor `input-modality-aware`	issues	high	The focus probe reports outline-style none on the first focusable anchor and five rendered links with heights from 12 to 20 px. F04 high: Keyboard focus is not visibly indicated on the first focusable link and several links have undersized hit areas.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	Google News, Your briefing, Top stories and source-labelled headlines make the page purpose and next reading actions explicit.
support-core-task-success `primary-flow-completion`	pass	high	The exercised home, topic and multi-source story URLs loaded and exposed crawlable headline links without requiring sign-in.
support-core-task-success `clear-system-state-and-recovery`	pass	high	Signed-out personalisation is clearly labelled with a Sign in action, while source and story states remain understandable; the separate HTTP failure weakness is recorded under resilience.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse reports performance 0.41, FCP 6.0 s, LCP 10.1 s, TBT 830 ms and time to interactive 14.1 s. The raw-CDP trace corroborates LCP 2.78 s and one 188.83 ms long task in a less-throttled run. F05 high: Cold-load performance is well outside the good range.
be-fast-and-stable `visual-stability`	pass	high	The layout observer measured CLS 0 in the capture window and Lighthouse measured CLS 0.006.
be-fast-and-stable `efficient-main-thread`	issues	high	Lighthouse measured 830 ms total blocking time and a 670 ms maximum potential input delay; the CDP trace found a 188.83 ms long task. F06 medium: Startup JavaScript blocks the main thread.
be-fast-and-stable `efficient-resource-delivery`	issues	high	The HAR records 120 requests and 1.46 MB transferred, including 367 KB of fonts. The Google Fonts stylesheet is parser-inserted at VeryHigh priority; Lighthouse flags LCP discovery and network dependency failures. F07 medium: Font and script delivery delays the critical path.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Lighthouse estimates 352 KiB of unused JavaScript and 199 KiB of unused CSS on the audited load. F08 medium: The home feed ships substantial unused JavaScript and CSS.
be-inclusive `names-roles-labels`	issues	high	Lighthouse identifies Top stories and Local news anchors where aria-label is prohibited because the elements have no valid role in the computed accessibility model. F09 medium: Some headline links carry prohibited ARIA attributes.
be-inclusive `sufficient-contrast`	pass	high	Lighthouse color-contrast scored 1 and forced-colours mode kept content readable.
be-inclusive `structure-and-focus`	issues	high	Lighthouse fails heading-order for article h4 elements. ui-probe records h1 followed by h3 sections and six empty h3 elements; it also records no nav landmark. F10 medium: Heading levels skip from section headings to h4 article headlines, and multiple source headings are empty.
be-inclusive `legible-text`	pass	high	Headline and metadata text remains readable with clear grouping and no visible clipping on the representative templates, apart from the separately reported viewport overflow.
be-inclusive `zoom-reflow-targets-and-media`	pass	high	The viewport meta audit passes and the page permits normal scaling; no essential audio/video requiring captions appeared. Target-size and horizontal reflow issues are separately recorded under input and form-factor checks.
follow-best-practices `no-console-errors`	pass	high	Lighthouse errors-in-console scored 1 and reported no console error items.
follow-best-practices `sound-document-and-assets`	pass	high	Lighthouse doctype, charset, image-alt, aspect-ratio and deprecated API audits pass; observed CLS is low despite missing explicit img dimensions.
follow-best-practices `browser-platform-hygiene`	issues	high	Lighthouse reports a large first-party script without a source map and three BFCache blockers, including cache-control: no-store on the main resource. F11 low: Large JavaScript lacks source maps and the page cannot use the back-forward cache.
be-discoverable `title-and-description`	pass	high	Home, topic and story each expose descriptive titles and meta descriptions.
be-discoverable `crawlable-and-mobile-friendly`	pass	high	Headline links have real href values, viewport meta passes, robots allows home/topics/stories for general crawlers, and Lighthouse SEO scores 1.
be-discoverable `canonical-and-indexing-signals`	pass	high	The audited URLs return 200, expose canonical URLs, appear under allowed robots patterns, and the fetched sitemap is populated.
be-discoverable `structured-and-shareable-metadata`	pass	high	Home, topic and story expose Organization or page JSON-LD plus matching Open Graph title, URL, description and image metadata.
be-private-and-secure `secure-transport-and-headers`	issues	high	The headers primitive confirms HTTPS and nosniff, but finds no HSTS or Referrer-Policy and a CSP containing unsafe-inline/unsafe-eval. F12 medium: The observed response weakens browser-enforced transport and script protections.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	The HAR attributes 83 of 120 requests and 1.12 MB of 1.46 MB transferred to other origins, including a 153 KB Google Tag Manager script. The tracker probe found no listed tracker match, but analytics collection appears in the HAR. F13 medium: Third-party delivery and analytics dominate the initial transfer.
be-private-and-secure `in-context-permissions-and-modern-auth`	pass	high	No geolocation, notification or media permission request was detected on load; the platform exposes WebAuthn and sign-in is optional for core reading.
be-private-and-secure `defensive-browser-policies`	issues	high	The headers primitive confirms HTTPS and nosniff, but finds no HSTS or Referrer-Policy and a CSP containing unsafe-inline/unsafe-eval. F12 medium: The observed response weakens browser-enforced transport and script protections.
be-resilient `progressive-enhancement`	issues	high	The discoverability primitive reports only 21% rendered-word coverage in raw HTML. Title, h1 and description survive, but the crawler screenshot contains only a small fraction of the rendered feed. F14 high: Most live news content is unavailable to a browser or crawler without JavaScript.
be-resilient `resilient-runtime-behaviour`	pass	high	Home, topic and story templates reached stable rendered states with intact controls and no clipped primary overlays in the desktop captures.
be-resilient `offline-and-installable`	pass	high	A standalone web app manifest with icons and start_url is present, and a service worker controls the news origin.
be-resilient `network-and-http-failure-states`	issues	high	The same-origin missing-route fetch failed with TypeError rather than returning a usable error document, while direct navigation was redirected to the consent surface instead of a contextual 404. F18 medium: A missing same-origin route did not provide a useful recoverable error response in the exercised client context.
be-internationalised `lang-dir-and-logical-properties`	pass	high	The document uses lang=en-GB and ltr direction; localized templates render coherently across home, topic and story.
be-internationalised `locale-aware-data`	pass	high	The UK surface uses en-GB labels, Sunday 19 July, Celsius weather and locale-appropriate relative publication ages.
be-internationalised `time-zone-correctness`	not-applicable	high	The audited reading surfaces contain relative publication ages but no scheduling, recurring-event or time-zone conversion flow.
be-trustworthy `no-dark-patterns`	pass	high	Reject all and Accept all are equally prominent, consent purposes are stated, and reading remains available without signing in once a choice is made.
be-trustworthy `humane-error-handling`	not-applicable	high	No user-submitted form with validation is present in the public signed-out reading paths; search is a suggestion field rather than a submitted validation flow.
be-trustworthy `trustworthy-input-assistance`	not-applicable	high	No address, payment, sign-up or credential form is present in the audited signed-out paths.
be-trustworthy `safe-commercial-and-account-flows`	not-applicable	high	No checkout, subscription purchase or account-management flow is present in the audited signed-out scope.
be-sustainable `optimised-assets`	issues	high	The image probe finds 100 of 100 img elements without width and height attributes and 38 oversized images, commonly 96 px favicon resources displayed at 14 px. Runtime CLS was low, so the risk is primarily waste and future instability rather than observed shift. F15 medium: Many rendered images lack intrinsic dimensions and small favicons are delivered oversized.
be-sustainable `no-wasteful-work`	issues	high	Lighthouse estimates 352 KiB of unused JavaScript and 199 KiB of unused CSS on the audited load. F08 medium: The home feed ships substantial unused JavaScript and CSS.
be-sustainable `third-party-and-media-budget`	issues	high	Third-party origins account for 1.12 MB of 1.46 MB transferred; fonts consume 367 KB and Google Tag Manager 153 KB before user interaction. F16 medium: Third-party scripts and fonts consume a disproportionate share of a text-heavy news feed.
be-agent-ready `structured-agent-capabilities`	issues	high	robots.txt explicitly disallows GPTBot, ChatGPT-User, PerplexityBot, anthropic-ai, ClaudeBot and Claude-Web. Lighthouse reports an agentic-browsing score of 0.33 and no llms.txt recommendation; raw content coverage is 21%. F17 medium: The public news surface is intentionally unavailable to major AI agents and exposes no structured action interface.
be-agent-ready `on-device-inference`	not-applicable	high	No user task in the audited public reading flow requires on-device generation; absence is not itself a failure.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	high	After ten bottom-to-top feed scroll cycles, heap grew from 32,673,352 to 32,909,762 bytes (0.7%) and node count from 559,430 to 562,219 (0.5%), with no unbounded-growth signal.
be-memory-efficient `bounded-footprint`	pass	high	The dense feed settles at about 32.7 MB self size; post-interaction growth is small and proportionate to loaded feed content.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	Top constructor populations remain nearly flat after repetition: closures rise 19,964 to 19,973, sets stay 1,570 and no Detached constructor appears in the reported top populations.
