All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	The dark-preference screenshots are pixel-identical in palette to the light screenshots; the probe reports color-scheme normal and no prefers-color-scheme CSS. F001 high: The site stays light when the user requests dark mode.
respect-user-preferences `respects-reduced-motion`	pass	high	Reduced-motion emulation reported zero active animations and no auto-advancing motion in the observed first viewport.
respect-user-preferences `respects-contrast`	pass	high	Forced-colors/high-contrast screenshot retains visible text, separators, controls and the primary headline.
implement-natural-interactions `view-transitions`	issues	high	Rendered CSS inspection found no view-transition rules, while navigation is a core interaction across the MPA. F002 medium: Route and menu state changes do not use View Transitions.
implement-natural-interactions `scroll-driven-animations`	not-applicable	high	No scroll-linked decorative motion was observed, so there is no scroll-event animation implementation to judge.
implement-natural-interactions `physical-gestures`	issues	high	The mobile probe found an initialized Swiper with a transformed wrapper, but no scroll-snap CSS. F003 medium: The horizontal game carousel is script-driven without platform scroll snapping.
provide-guided-navigation `scroll-state-aware-chrome`	issues	high	CSS inspection found no scroll-state container query or scroll progress implementation across a 15,712px homepage. F004 medium: The long news page has no scroll-state-aware navigation or progress cue.
provide-guided-navigation `anchored-positioning`	not-applicable	high	No tooltip or viewport-edge popover is part of the representative reading and listing flows.
provide-guided-navigation `directs-attention`	pass	high	Current section labels, strong hierarchy and prominent article headlines make location and next destinations clear across section and article templates.
maximize-content-reduce-noise `no-intrusive-interruptions`	issues	high	Desktop and mobile screenshots show a fixed subscription banner covering the lower 175px, about 22% of the mobile viewport, immediately on load. F005 high: A fixed subscription promotion obscures primary content on the homepage.
maximize-content-reduce-noise `semantic-dismissible-primitives`	issues	high	The DOM probe identifies ASIDE#banda_suscripcion as a fixed 360x175 overlay; no dialog or popover primitive is used. F006 medium: The subscription interruption is an ad-hoc fixed aside rather than a semantic overlay.
maximize-content-reduce-noise `reduced-chrome`	pass	high	Outside the subscription interruption, article and section templates use restrained borders and keep headlines/content visually dominant.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	issues	high	Layout evidence on both homepage and article reports scrollWidth 720px at innerWidth 360px, with 360px horizontal overflow. F007 high: Mobile layouts create a document twice the viewport width.
adapt-to-the-form-factor `component-level-responsiveness`	issues	high	Rendered CSS inspection found no @container or container-type despite card components being reused across homepage, section, and sidebars. F008 medium: Repeated cards and navigation rely on viewport rules, not component containment.
adapt-to-the-form-factor `input-modality-aware`	issues	high	Lighthouse target-size failed; the focus probe also measured many topical links at only 11px high. F009 medium: Several mobile controls are too small or tightly spaced.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	Homepage, section and latest pages immediately identify themselves and expose current headlines as direct links.
support-core-task-success `primary-flow-completion`	pass	high	The homepage-to-article journey loaded a full headline, dek, image and server-rendered article content without an account wall.
support-core-task-success `clear-system-state-and-recovery`	pass	high	The tested missing sitemap URL returns HTTP 404 with an explicit Spanish page-not-found template rather than a blank or false-success page.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse measured LCP 28.6s, FCP 10.7s, TBT 1,120ms and a 0.32 performance score; the CDP trace corroborated a 563ms longest task and 549ms TBT. F010 critical: The primary landing page is very slow and main-thread heavy.
be-fast-and-stable `visual-stability`	issues	high	The mobile layout observer recorded CLS 2.001 with two late shifts of 1.0 around 6.5s, coinciding with late fixed/personalization UI. F011 high: Late homepage UI causes severe observed layout movement.
be-fast-and-stable `efficient-main-thread`	issues	high	Lighthouse measured LCP 28.6s, FCP 10.7s, TBT 1,120ms and a 0.32 performance score; the CDP trace corroborated a 563ms longest task and 549ms TBT. F010 critical: The primary landing page is very slow and main-thread heavy.
be-fast-and-stable `efficient-resource-delivery`	issues	high	The HAR recorded 264 requests and 4.71MB transferred, including 82 scripts totaling 3.41MB; Lighthouse estimated 4.92s render-blocking savings. F012 high: The page ships an oversized, third-party-dominated dependency graph.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Lighthouse estimated 1,480KiB of unused JavaScript and 35KiB unused CSS; third-party scripts dominate the largest transfer list. F013 high: Large amounts of JavaScript are unused during the initial news-reading task.
be-inclusive `names-roles-labels`	issues	high	Lighthouse failed frame-title; the article probe found multiple untitled advertising/paywall iframes, and the images primitive counted 33 images without alt attributes. F014 high: Embedded frames and many images lack accessible text alternatives.
be-inclusive `sufficient-contrast`	pass	high	Lighthouse accessibility scored 0.94 with no color-contrast failure, and forced-colors preserved readable text.
be-inclusive `structure-and-focus`	pass	high	Pages expose main/nav landmarks and skip links; focused controls receive a visible browser outline in the keyboard probe.
be-inclusive `legible-text`	pass	high	Article and listing screenshots show readable line lengths, clear serif hierarchy, and no text clipping in the main content column.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	Layout evidence on both homepage and article reports scrollWidth 720px at innerWidth 360px, with 360px horizontal overflow. Lighthouse target-size failed; the focus probe also measured many topical links at only 11px high. F007 high: Mobile layouts create a document twice the viewport width. F009 medium: Several mobile controls are too small or tightly spaced.
follow-best-practices `no-console-errors`	issues	high	Lighthouse failed errors-in-console, and HAR hygiene recorded SSL, ORB, aborted analytics, and localhost connection failures. F015 medium: The page logs browser errors during a normal load.
follow-best-practices `sound-document-and-assets`	issues	high	The images primitive found three images without width/height; Lighthouse also failed unsized-images. The document reports ISO-8859-15 rather than UTF-8. F016 medium: Some images lack intrinsic dimensions and the document uses a legacy encoding.
follow-best-practices `browser-platform-hygiene`	issues	high	Lighthouse reported three deprecation warnings, two BFCache failure reasons, and DevTools inspector issues. F017 medium: Deprecated APIs and platform lifecycle blockers remain.
be-discoverable `title-and-description`	pass	high	Homepage and article expose descriptive titles and meta descriptions, with article-specific values.
be-discoverable `crawlable-and-mobile-friendly`	issues	high	Lighthouse failed crawlable-anchors; the article probe counted 45 href="#" anchors. F018 medium: Some visible actions are exposed as hash links rather than crawlable destinations.
be-discoverable `canonical-and-indexing-signals`	issues	high	/sitemap.xml returned 404 and the fetched robots.txt contained no Sitemap declaration, while pages themselves had valid canonicals and index directives. F019 low: No sitemap is advertised at the conventional endpoint or in robots.txt.
be-discoverable `structured-and-shareable-metadata`	pass	high	The article exposes NewsArticle/ReportageNewsArticle and BreadcrumbList JSON-LD plus complete Open Graph title, description, URL, image and type.
be-private-and-secure `secure-transport-and-headers`	issues	high	The headers primitive found no CSP, HSTS, nosniff, clickjacking protection, or Permissions-Policy and found Referrer-Policy unsafe-url. All 44 observed cookies were flagged insecure by the cookie audit. F020 high: Core security headers are absent and cookies are broadly insecure.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	The tracker audit found 64 third-party origins and 14 known tracker hosts. HAR classified 255 of 264 requests and 4.61MB of 4.71MB as third-party. F021 critical: Tracking and advertising dominate the initial page load.
be-private-and-secure `in-context-permissions-and-modern-auth`	issues	high	No passkey, WebAuthn, or navigator.credentials marker appeared in the server HTML, although sign-in is a prominent account action; no permission prompt fired on load. F022 medium: The visible sign-in surface has no detectable passkey/WebAuthn support.
be-private-and-secure `defensive-browser-policies`	issues	high	The headers primitive found no CSP, HSTS, nosniff, clickjacking protection, or Permissions-Policy and found Referrer-Policy unsafe-url. All 44 observed cookies were flagged insecure by the cookie audit. F020 high: Core security headers are absent and cookies are broadly insecure.
be-resilient `progressive-enhancement`	pass	high	Non-JavaScript crawler coverage is 96% on home, 99% on section and 89% on article; none is a JS shell.
be-resilient `resilient-runtime-behaviour`	pass	high	Representative mobile and desktop pages render usable navigation and content without clipped primary controls or broken shells.
be-resilient `offline-and-installable`	not-applicable	high	This public news publication is content-first rather than an installed application; offline installability is not required for the audited core reading journey.
be-resilient `network-and-http-failure-states`	pass	high	The representative HTTP 404 response is intentional, descriptive and does not masquerade as a success state.
be-internationalised `lang-dir-and-logical-properties`	pass	high	The root language is correctly es and visible content uses Spanish reading order; no bidirectional content appears in scope.
be-internationalised `locale-aware-data`	pass	high	Dates are rendered in Spanish long-date form, for example “Domingo, 26 de julio de 2026”.
be-internationalised `time-zone-correctness`	not-applicable	high	The audited news reading and listing paths contain publication dates but no scheduled cross-time-zone event or recurring-time flow.
be-trustworthy `no-dark-patterns`	pass	high	Navigation labels and article links are descriptive, and no confirmshaming control or disguised ad action was observed in the representative paths.
be-trustworthy `humane-error-handling`	not-applicable	high	No authored data-entry form or invalid-submission flow appeared in the representative news reading paths.
be-trustworthy `trustworthy-input-assistance`	not-applicable	high	No authored sign-up, address, payment, or account input was exposed in the audited paths; account UI is externally mediated.
be-trustworthy `safe-commercial-and-account-flows`	issues	high	The fixed offer says 0.50 euros per month and more than 90% discount, but the visible viewport does not state the renewal price or commitment. F023 medium: The subscription teaser does not disclose the price after the introductory month in context.
be-sustainable `optimised-assets`	issues	high	The images audit found 36 images without srcset, 44 legacy-format image URLs, no modern-format img sources, and eight below-fold images not lazy-loaded. F024 high: Image delivery is not consistently responsive or modern.
be-sustainable `no-wasteful-work`	issues	high	Third parties account for 4.61MB and 255 requests, including many advertising, experimentation, social and analytics SDKs before interaction. F025 high: Third-party resource use is disproportionate to initial article discovery.
be-sustainable `third-party-and-media-budget`	issues	high	Third parties account for 4.61MB and 255 requests, including many advertising, experimentation, social and analytics SDKs before interaction. F025 high: Third-party resource use is disproportionate to initial article discovery.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	The publication exposes machine-readable articles but no transactional capability that would justify WebMCP tools in this audit.
be-agent-ready `on-device-inference`	not-applicable	high	On-device summarization is an emerging optional enhancement, not required for the publication’s core reading task.
be-memory-efficient `no-leak-under-repeated-interaction`	issues	medium	Within one session, ten open/close cycles increased DOM elements from 2,824 to 2,854 and used JS heap from 70.7MB to 82.5MB. Separate heap snapshots grew from 69.1MB to 72.3MB self size. F026 medium: Repeated menu toggling leaves measurable growth after the interaction ends.
be-memory-efficient `bounded-footprint`	issues	medium	The baseline heap snapshot contained 1,168,886 heap nodes and 69.1MB self size after load, alongside 3.41MB of transferred scripts. F027 medium: The baseline memory footprint is heavy for a mobile news landing page.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	issues	medium	Within one session, ten open/close cycles increased DOM elements from 2,824 to 2,854 and used JS heap from 70.7MB to 82.5MB. Separate heap snapshots grew from 69.1MB to 72.3MB self size. F026 medium: Repeated menu toggling leaves measurable growth after the interaction ends.
