All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	White surfaces remain unchanged under dark preference. F01 medium: The site does not adapt its surfaces to a dark color preference.
respect-user-preferences `respects-reduced-motion`	issues	high	15 two-second skeleton animations remain active and no reduced-motion media rule was found. F02 low: Loading animations continue when reduced motion is requested.
respect-user-preferences `respects-contrast`	pass	medium	The document permits UA forced-color adaptation (forced-color-adjust:auto) and advertises light/dark color scheme.
implement-natural-interactions `view-transitions`	issues	medium	No view-transition treatment was present for route or state changes. F03 low: Route and state changes do not use coherent view transitions.
implement-natural-interactions `scroll-driven-animations`	issues	medium	The 67,509 px feed has no scroll-timeline or progress treatment. F04 low: The long feed has no scroll-linked progress or spatial feedback.
implement-natural-interactions `physical-gestures`	pass	medium	Native vertical scrolling remains available without horizontal overflow; persistent mobile navigation targets are 42 px high.
provide-guided-navigation `scroll-state-aware-chrome`	pass	medium	A persistent bottom navigation keeps Home, Sections, Foodit, Club and Account available across tested templates.
provide-guided-navigation `anchored-positioning`	pass	medium	Menus, consent dialog and bottom navigation are positioned relative to their intended viewport/component without clipping.
provide-guided-navigation `directs-attention`	pass	high	Lead headline, section label and dollar data are visually prioritized above secondary cards once prompts are dismissed.
maximize-content-reduce-noise `no-intrusive-interruptions`	issues	high	A viewport-filling consent dialog blocks each path; desktop also stacks a notification prompt. F05 high: Consent and notification prompts obscure the primary news content on every tested archetype.
maximize-content-reduce-noise `semantic-dismissible-primitives`	pass	high	The consent surface is exposed as role=dialog with a label, focus target and option controls.
maximize-content-reduce-noise `reduced-chrome`	issues	high	Prompts, ad inventory and mixed modules dominate the opening and create a 67,509 px homepage. F06 medium: Advertising, prompts and a very long mixed-content feed compete with the primary news task.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	pass	high	All four layouts report scrollWidth=clientWidth=360 and horizontalOverflowPx=0.
adapt-to-the-form-factor `component-level-responsiveness`	pass	high	Cards collapse to mobile columns and navigation changes to a bottom bar without clipping.
adapt-to-the-form-factor `input-modality-aware`	pass	medium	Primary mobile navigation targets are 42 px high and standard button/link semantics preserve keyboard and touch input.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	The publication purpose and lead story are explicit; article, section and dollar templates expose task-specific headings.
support-core-task-success `primary-flow-completion`	issues	high	Every primary path is initially blocked by consent. F07 high: Reading is interrupted before the primary flow can begin.
support-core-task-success `clear-system-state-and-recovery`	pass	medium	Consent presents labeled choices and the dollar template exposes current values; standard page navigation remains available.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse LCP 8.6 s, FCP 5.6 s and TBT 1,070 ms; trace LCP was 1.67 s unthrottled. F08 high: Mobile load performance is poor despite acceptable visual stability.
be-fast-and-stable `visual-stability`	pass	high	Observed CLS ranges 0.021–0.052 with no horizontal overflow, within the good threshold.
be-fast-and-stable `efficient-main-thread`	issues	high	Lighthouse TBT is 1,070 ms and TTI 33.8 s; trace captured tasks up to 95 ms. F09 high: Main-thread work delays interactivity.
be-fast-and-stable `efficient-resource-delivery`	issues	high	188 requests transfer 4.07 MB, including 2.82 MB script. F10 high: The homepage transfers a large, script-heavy payload.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Multiple GTM/gtag and ad-tech scripts dominate transferred bytes. F11 high: Third-party and duplicated tag code dominates the payload.
be-inclusive `names-roles-labels`	issues	high	A focusable Prode link and several visible controls have no discernible name. F12 medium: Some interactive controls and links lack accessible names.
be-inclusive `sufficient-contrast`	issues	high	Consent text ratios of 1.82:1 and 2.8:1 fail 4.5:1. F13 medium: Consent dialog text fails contrast requirements.
be-inclusive `structure-and-focus`	pass	medium	Pages use a single content H1 before section headings; the consent dialog is labeled and focusable.
be-inclusive `legible-text`	pass	medium	Article and headline text remains readable and reflows at 360 px without clipping.
be-inclusive `zoom-reflow-targets-and-media`	pass	medium	No horizontal overflow occurs and primary mobile navigation targets are 42 px high.
follow-best-practices `no-console-errors`	issues	high	Normal load logs FedCM, CORS, network and 404 errors. F14 medium: Production loads emit console and network errors.
follow-best-practices `sound-document-and-assets`	pass	high	HTML doctype, UTF-8 charset, viewport metadata and canonical metadata are present; missing image dimensions are handled under performance/sustainability.
follow-best-practices `browser-platform-hygiene`	issues	high	Deprecated Attribution Reporting use and an unload handler preventing bfcache were reported. F15 medium: Deprecated APIs and an unload handler reduce browser compatibility and navigation performance.
be-discoverable `title-and-description`	pass	high	Home and article have descriptive titles and meta descriptions in raw HTML.
be-discoverable `crawlable-and-mobile-friendly`	pass	high	Raw HTML coverage is 96% home and 89% article; robots allows public content and four mobile templates have no overflow.
be-discoverable `canonical-and-indexing-signals`	pass	high	Canonical URLs, max-image-preview robots metadata and multiple declared sitemap indexes are present.
be-discoverable `structured-and-shareable-metadata`	pass	high	Home has three JSON-LD blocks and Open Graph metadata; article has five JSON-LD blocks and Open Graph metadata.
be-private-and-secure `secure-transport-and-headers`	issues	high	HTTPS is used, but HSTS, nosniff, Referrer-Policy and Permissions-Policy are absent. F16 high: HTTPS is used, but important transport and response protections are absent.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	53 third-party origins, 14 known tracker domains, 134 third-party requests and insecure/long-lived cookies were observed. F17 high: The page exposes readers to an unusually broad tracking and advertising surface.
be-private-and-secure `in-context-permissions-and-modern-auth`	pass	medium	Notification permission is requested through an in-page prompt rather than immediate browser permission; sign-in is user initiated. No sensitive secrets were found.
be-private-and-secure `defensive-browser-policies`	issues	high	CSP only declares frame-ancestors and other defensive policies are absent. F18 high: Defensive browser policies are incomplete.
be-resilient `progressive-enhancement`	pass	high	Core content is server-rendered: 96% home and 89% article token coverage without JavaScript.
be-resilient `resilient-runtime-behaviour`	issues	high	Optional identity/ad integrations emit multiple errors during normal load. F19 medium: Third-party failures leak into the production runtime.
be-resilient `offline-and-installable`	pass	medium	A standalone manifest with icons/screenshots and an active service worker registration are present.
be-resilient `network-and-http-failure-states`	issues	medium	Fresh Cache Storage is empty and a missing route returns an unadorned 404 response. F20 medium: The installable surface has no observable cached fallback in a fresh session.
be-internationalised `lang-dir-and-logical-properties`	pass	high	The document declares lang=es; Spanish content and responsive layouts render in the expected left-to-right direction.
be-internationalised `locale-aware-data`	pass	medium	Argentine peso/dollar values, decimal commas and Spanish labels are localized consistently on home and dollar paths.
be-internationalised `time-zone-correctness`	pass	medium	Article publication/current-market context is presented consistently for the Argentine edition without contradictory timezone rendering.
be-trustworthy `no-dark-patterns`	issues	high	The first layer offers Accept and Manage but no equally direct Reject all while blocking content. F21 high: Consent choice architecture favors acceptance.
be-trustworthy `humane-error-handling`	pass	medium	No user-entered form error is shown on the audited public paths; consent controls use plain Spanish labels and remain reversible through management.
be-trustworthy `trustworthy-input-assistance`	not-applicable	high	No user data-entry form is present on the home/article/section/dollar templates.
be-trustworthy `safe-commercial-and-account-flows`	pass	medium	Subscription price and account links are visibly labeled; no checkout was entered because it leaves the audited origin.
be-sustainable `optimised-assets`	issues	high	93 images lack dimensions, 87 lack srcset and 93 use legacy formats. F22 high: Image delivery is not responsive or format-efficient.
be-sustainable `no-wasteful-work`	issues	high	4.07 MB/188 requests load initially and 15 skeleton animations continue under reduced motion. F23 high: Substantial work runs before the reader has chosen optional processing.
be-sustainable `third-party-and-media-budget`	issues	high	Third parties account for 2.90 MB and 134 requests. F24 high: Third-party bytes exceed a reasonable news-page budget.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	This is a public editorial reading surface, not an agent-operable application; discoverability is covered separately.
be-agent-ready `on-device-inference`	not-applicable	high	No summarization or local-AI feature is offered or required for the core reading task.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	medium	Separate fresh runs show a modest 2.4 MB (3%) difference with no Detached constructor among top retained types; this does not establish a leak.
be-memory-efficient `bounded-footprint`	issues	medium	Baseline has 1.32 million nodes and 79.3 MB self size, high for an initial news page. F25 medium: The homepage has a high baseline heap and DOM footprint.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	medium	No Detached DOM constructor appears among top retained constructors after repeated scrolling; object growth is modest and non-diagnostic.
