Coverage complete

Coverage-complete representative audit of five public templates/journeys. Not covered: authenticated account internals, completed payment, personalized logged-in states, live search submission, and real offline transport because they require credentials, financial commitment, or broader destructive/environmental controls.

All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	pass	high	Under explicit light and dark emulation the body changes from transparent/light to rgb(33,33,33); the site also exposes a day/night mode.
respect-user-preferences `respects-reduced-motion`	pass	high	With prefers-reduced-motion: reduce, the probe found no active animations or autoplay media.
respect-user-preferences `respects-contrast`	issues	high	Lighthouse found three contrast failures, including 1.82:1 in the consent control; no high-contrast adaptation was visible. F02 medium: Some text and controls fail minimum contrast, including inside the consent UI.
implement-natural-interactions `view-transitions`	issues	medium	Representative MPA route changes showed no observed transition animation. F03 low: Full-page route changes do not expose a view-transition treatment.
implement-natural-interactions `scroll-driven-animations`	pass	high	No scroll-linked visual effect was present on sampled templates, so no main-thread scroll-animation anti-pattern affected the experience.
implement-natural-interactions `physical-gestures`	pass	medium	Primary interactions use native links, scrolling, checkboxes and buttons; no gesture surface that fights platform scrolling was observed.
provide-guided-navigation `scroll-state-aware-chrome`	issues	high	The primary header is position:static on a 17,149px feed and no progress/state cue was observed. F04 low: The primary header is static rather than scroll-state aware.
provide-guided-navigation `anchored-positioning`	pass	medium	The sampled overlays are centered modal surfaces rather than edge-attached tooltips/popovers; no drifting anchored UI was observed.
provide-guided-navigation `directs-attention`	pass	high	Section labels, story hierarchy and the 404 recovery page visibly direct users to relevant next destinations.
maximize-content-reduce-noise `no-intrusive-interruptions`	issues	high	A blocking consent modal obscures every sampled primary page on first load. F01 high: A consent wall obscures every sampled content and commercial page on first load.
maximize-content-reduce-noise `semantic-dismissible-primitives`	issues	high	Probe found four role=dialog containers, one dialog and no popovers; visible consent UI is custom modal chrome. F05 low: Modal UI relies predominantly on custom role=dialog containers.
maximize-content-reduce-noise `reduced-chrome`	issues	high	Multiple stacked promo/navigation bands plus the blocking CMP dominate the first viewport. F06 medium: The first viewport is crowded with promos, live-topic bars and ad/consent chrome.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	pass	high	At 360x800, scrollWidth equals clientWidth (360px), horizontal overflow is 0 and viewport meta is present.
adapt-to-the-form-factor `component-level-responsiveness`	issues	medium	Sampled core containers report container-type:normal; no component-level container adaptation was evidenced. F07 low: Core sampled containers do not expose component-level responsiveness.
adapt-to-the-form-factor `input-modality-aware`	issues	high	Focused menu control has no outline/box-shadow and 110 rendered targets are under 24px in one dimension. F08 high: Keyboard focus and touch-target support are incomplete.
support-core-task-success `clear-purpose-and-primary-action`	issues	high	The editorial purpose is clear behind the page, but a first-load consent wall hides it on all core paths. F01 high: A consent wall obscures every sampled content and commercial page on first load.
support-core-task-success `primary-flow-completion`	pass	medium	Homepage links lead to a readable article and section; subscription offers expose prices and subscribe actions without a dead end in the sampled pre-purchase flow.
support-core-task-success `clear-system-state-and-recovery`	pass	high	The missing route explains that content is unavailable and offers portada, latest-news, dollar, games and horoscope recovery links.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse: LCP 7.0s, TBT 2,110ms, performance 28; independent trace LCP 8.79s. F09 high: Cold-load performance is poor.
be-fast-and-stable `visual-stability`	pass	high	Measured CLS is 0.078 in Lighthouse, 0.082 mobile and 0.013 desktop, all below the 0.1 good threshold.
be-fast-and-stable `efficient-main-thread`	issues	high	Lighthouse TBT is 2,110ms; trace records five long tasks up to 118ms. F10 high: Heavy scripting blocks the main thread.
be-fast-and-stable `efficient-resource-delivery`	issues	high	557 requests transfer 13.44MB and a parser-inserted zonda script is neither async nor defer. F11 high: The homepage network dependency graph is extremely large.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Lighthouse estimates 1,674KiB unused JS and 61KiB unused CSS. F12 high: The page ships substantial unused JavaScript and CSS.
be-inclusive `names-roles-labels`	issues	high	Lighthouse fails link-name; probe finds eight unlabelled controls and 70 empty unnamed links. F13 medium: Some interactive controls lack usable accessible names or labels.
be-inclusive `sufficient-contrast`	issues	high	Lighthouse finds three insufficient-contrast nodes, including a 1.82:1 consent label. F02 medium: Some text and controls fail minimum contrast, including inside the consent UI.
be-inclusive `structure-and-focus`	issues	high	No main landmark exists; consent markup adds multiple H1s; keyboard focus is visually absent on the menu control. F14 high: Landmark and heading structure is polluted by consent markup. F08 high: Keyboard focus and touch-target support are incomplete.
be-inclusive `legible-text`	pass	medium	Article headline, deck and listing copy render at readable sizes with clear typographic hierarchy in sampled desktop/mobile screenshots.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	Viewport permits user scaling and mobile reflow has no overflow, but 110 interactive targets are below 24px in one dimension. F08 high: Keyboard focus and touch-target support are incomplete.
follow-best-practices `no-console-errors`	issues	high	Lighthouse records seven console/network errors including CORS, FedCM and JW Player failures. F15 medium: The page logs multiple runtime and network errors.
follow-best-practices `sound-document-and-assets`	issues	high	Doctype and UTF-8 are valid, but image audit finds 9 missing dimensions and broad sizing/format inefficiency. F16 high: Image delivery is wasteful across the long news feed.
follow-best-practices `browser-platform-hygiene`	issues	high	Lighthouse detects notification permission requested on load and a BFCache failure. F17 high: The page requests notification permission on load and is not BFCache eligible.
be-discoverable `title-and-description`	pass	high	Homepage and article have unique descriptive titles and meta descriptions.
be-discoverable `crawlable-and-mobile-friendly`	pass	high	All 1,038 sampled anchors have hrefs, viewport metadata is present, robots permits indexing and raw content is available.
be-discoverable `canonical-and-indexing-signals`	pass	high	Homepage and article expose matching canonicals; robots says all/max-image-preview and sitemap/robots endpoints respond with indexing directives.
be-discoverable `structured-and-shareable-metadata`	pass	high	Homepage has six JSON-LD blocks and seven Open Graph tags; article has five JSON-LD blocks and complete article OG title/description/image/url metadata.
be-private-and-secure `secure-transport-and-headers`	issues	high	HTTPS is used, but all six inspected security header families are absent and many cookies lack Secure. F18 critical: Baseline browser security policies and cookie flags are missing.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	63 third-party origins, 16 known trackers, 355 third-party requests and 6.61MB third-party transfer occur on first load. F19 critical: The anonymous first load has an outsized third-party tracking footprint.
be-private-and-secure `in-context-permissions-and-modern-auth`	issues	high	Lighthouse detected a notification prompt on load, which is not contextual; account entry exists but modern auth could not be verified before sign-in. F17 high: The page requests notification permission on load and is not BFCache eligible.
be-private-and-secure `defensive-browser-policies`	issues	high	HSTS, clickjacking protection, CSP, Referrer-Policy and Permissions-Policy are all absent. F18 critical: Baseline browser security policies and cookie flags are missing.
be-resilient `progressive-enhancement`	pass	high	Raw HTML contains 91% of rendered content words, including title/H1/description; crawler view is substantive, not a JS shell.
be-resilient `resilient-runtime-behaviour`	pass	medium	Sampled centered overlays remain within desktop/mobile viewports and missing-route navigation remains usable.
be-resilient `offline-and-installable`	not-applicable	high	Clarín is primarily a public news/content MPA rather than an installed app; offline installability was not treated as a required core task.
be-resilient `network-and-http-failure-states`	pass	high	A missing URL renders a complete, explanatory recovery page with multiple useful destinations instead of a blank shell.
be-internationalised `lang-dir-and-logical-properties`	pass	high	The document declares lang=es and Spanish reading order is correct on all sampled templates.
be-internationalised `locale-aware-data`	pass	medium	Visible dates and Argentine subscription prices are formatted in Spanish/Argentine conventions, e.g. “sábado, 18 de julio de 2026” and $1.978.
be-internationalised `time-zone-correctness`	not-applicable	high	The sampled public pages expose publication/calendar text but no user-scheduled or cross-time-zone transaction to validate.
be-trustworthy `no-dark-patterns`	pass	medium	The CMP is intrusive, but accept and reject are both explicit, similarly styled actions; subscription cards disclose introductory and later monthly prices plus cancellation copy.
be-trustworthy `humane-error-handling`	issues	high	Required-field messages are English on a Spanish page and invalid controls lack aria-invalid/aria-describedby. F20 medium: The Spanish subscription form falls back to unconnected English browser error messages.
be-trustworthy `trustworthy-input-assistance`	issues	high	Personal-data fields in the subscription form omit autocomplete tokens. F21 high: The subscription contact form omits autocomplete tokens for personal data.
be-trustworthy `safe-commercial-and-account-flows`	pass	medium	Subscription offers show promotional and subsequent monthly prices, “Cancelá cuando quieras. Sin cargos”, login and telephone options before commitment.
be-sustainable `optimised-assets`	issues	high	Image audit reports 91 non-lazy below-fold, 79 without srcset, 94 legacy-format and 37 oversized images. F16 high: Image delivery is wasteful across the long news feed.
be-sustainable `no-wasteful-work`	issues	high	First load performs 557 requests including 163 XHR/fetch and remains interactive only after 74.6s. F22 high: Background integrations perform disproportionate work before core content settles.
be-sustainable `third-party-and-media-budget`	issues	high	Third parties account for 355 requests and 6.61MB; player imagery and scripts are among the top byte offenders. F19 critical: The anonymous first load has an outsized third-party tracking footprint. F11 high: The homepage network dependency graph is extremely large.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	The public news site exposes crawlable SSR content but no declared agent transaction/tool surface requiring WebMCP.
be-agent-ready `on-device-inference`	not-applicable	high	No user-facing on-device summarization or language-model feature is part of the sampled core news/subscription journeys.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	medium	After ten full-feed bottom/top cycles, heap self-size changed only +6,997 bytes and entry count +1,395 between comparable isolated captures; major object/closure populations did not grow.
be-memory-efficient `bounded-footprint`	issues	high	Baseline heap summary is 144,877,541 self-size bytes across 2,452,687 entries, disproportionate for a news listing. F23 high: The homepage has a very large steady-state heap for a news listing.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	medium	No Detached* constructor appears among summarized dominant constructors, and closures decline from 166,932 to 165,782 after repeated scrolling.
