Coverage complete
Coverage-complete audit across homepage, section, article, and invalid-route recovery. Noticias subdomain returned Access Denied, so equivalent www.uol.com.br sports templates were used. Search, authenticated account, subscription checkout/cancellation, and payment were not covered because they require broader cross-property or credentialed flows.

This report has no published overall score. Blocked and not-run checks are not passes. A coverage-complete report means every check has a judged outcome; it does not mean every check passed.
All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | The dark-condition screenshot is visually the same white interface as the default and the feature probe found zero prefers-color-scheme rules. F01 medium: System dark mode is ignored |
respect-user-preferencesrespects-reduced-motion | issues | high | With prefers-reduced-motion: reduce active, 13 animations remained running with durations of 1 to 3 seconds. F02 medium: Motion continues under reduced-motion preference |
respect-user-preferencesrespects-contrast | issues | high | The CSS feature probe found no prefers-contrast or forced-colors rules; the high-contrast screenshot retained the same low-emphasis chrome. F03 low: No explicit high-contrast adaptation |
implement-natural-interactionsview-transitions | issues | high | Rendered HTML and accessible CSS contained no view-transition or startViewTransition usage across the homepage navigation surface. F04 low: Route changes do not use View Transitions |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No scroll-linked animation was observed, so there is no scroll-handler implementation to assess. |
implement-natural-interactionsphysical-gestures | pass | medium | Feature probe found platform overscroll behavior and no inline pointer/touch-move handlers; reading uses native scrolling. |
provide-guided-navigationscroll-state-aware-chrome | issues | high | The homepage is 17,705 CSS pixels tall, while the feature probe found no scroll-state queries or scroll-timeline indicator. F05 low: Long news feed has no scroll-state guidance |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip, anchored popover, or edge-positioned menu was exercised in the representative core reading paths. |
provide-guided-navigationdirects-attention | pass | medium | Desktop and mobile screenshots show strong lead-headline hierarchy, section labels, and clear article context. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | Fresh sports loads are covered by a modal on desktop and mobile; body scrolling is locked and the dialog describes sharing with 211 partners. F06 high: Consent modal blocks the section before content can be used |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | The consent probe found role=dialog on a DIV without aria-modal; no dialog or popover primitive exists on the homepage. F07 medium: Consent overlay is a custom div rather than a modal primitive |
maximize-content-reduce-noisereduced-chrome | issues | high | The desktop first viewport gives roughly 300px to a blank advertising slot plus multiple header rows before the lead headline, and the mobile page remains dense. F08 medium: Advertising and service chrome crowds the primary news content |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | The homepage forces a 1210px layout viewport at 360px, while the article reports 85px horizontal overflow and visibly overlaps the title, navigation, currency, and subscription controls. F09 critical: Mobile layouts are broken or scaled down |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | high | The feature probe found no container queries, and the article header components overlap at 360px instead of re-composing. F10 high: Shared components do not adapt to their available space |
adapt-to-the-form-factorinput-modality-aware | issues | high | Homepage focus sampling found top navigation links only about 14px high and multiple links/inputs with outline none; some controls are 24x24. F11 high: Several controls are too small or lose visible focus |
support-core-task-successclear-purpose-and-primary-action | pass | medium | Homepage and article screenshots present a clear news portal purpose and prominent lead/article reading actions. |
support-core-task-successprimary-flow-completion | issues | high | At 360px the article headline and header controls overlap, the page is wider than the viewport, and the cookie banner obscures the opening paragraphs. F12 critical: The mobile article reading journey is obstructed |
support-core-task-successclear-system-state-and-recovery | issues | high | A deliberately invalid path redirected to https://www.uol.com.br/#404 but displayed normal homepage content, with no not-found heading, explanation, search, or recovery state. F13 high: Invalid URLs silently become the homepage |
be-fast-and-stablegood-core-web-vitals | issues | high | Lighthouse measured LCP 6.7s, Speed Index 10.1s, TTI 17.2s, and performance score 0.56. F14 high: Homepage load performance misses the user-centric bar |
be-fast-and-stablevisual-stability | pass | medium | Layout observer measured CLS 0.000069 on home and 0 on the article during the observation windows. |
be-fast-and-stableefficient-main-thread | issues | high | Lighthouse measured 280ms TBT; the trace found four long tasks, up to 113ms, and 99.89ms trace TBT. F15 medium: Main-thread work causes blocking tasks |
be-fast-and-stableefficient-resource-delivery | issues | high | The HAR captured 192 requests and 2.61MB transferred, including 56 scripts/1.90MB; fonts took about 2.1s. Parser-discovered candidates were confirmed async where sampled, but the network dependency volume remains high. F16 high: Resource delivery is dominated by scripts and third parties |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | Lighthouse estimated 897KiB unused JavaScript, led by player, advertising, analytics, consent, and bidding bundles. F17 high: Nearly 900KiB of JavaScript is unused on load |
be-inclusivenames-roles-labels | issues | high | axe found critical missing image alt, two unnamed links, 24 prohibited ARIA uses, and focusable controls inside aria-hidden carousels; the DOM probe found unlabeled email/password inputs. F18 high: Accessible names and roles are incomplete |
be-inclusivesufficient-contrast | issues | high | axe reported 54 color-contrast failures, including weather text and promoted headline text. F19 high: Many text elements fail WCAG contrast |
be-inclusivestructure-and-focus | issues | high | axe found no main landmark, incorrect heading order, empty headings, non-unique/nested landmarks, and aria-hidden focusable carousel content. F20 high: Document structure and focus semantics are unreliable |
be-inclusivelegible-text | issues | high | At 360px the article title is covered by header/navigation controls and body content is clipped/obscured. F21 critical: Article text is not legible at a common mobile width |
be-inclusivezoom-reflow-targets-and-media | issues | high | The article overflows by 85px at 360px and homepage target sampling found links around 14px high and 24x24 controls. F22 high: Reflow and target sizing fail on mobile |
follow-best-practicesno-console-errors | issues | high | Lighthouse captured CORS errors and failed Adnxs network requests in the console. F23 medium: Third-party integrations log runtime failures |
follow-best-practicessound-document-and-assets | issues | high | The images audit found 90 of 100 images missing dimensions, 21 below-fold images not lazy-loaded, and two missing alts; axe also flagged a delayed meta refresh. F24 medium: Asset markup creates avoidable risk |
follow-best-practicesbrowser-platform-hygiene | issues | high | Lighthouse found an unload handler that blocks BFCache and missing/broken maps for large first-party/player JavaScript. F25 medium: The page blocks BFCache and has source-map defects |
be-discoverabletitle-and-description | pass | medium | DOM and Lighthouse confirm descriptive titles and meta descriptions on home and article. |
be-discoverablecrawlable-and-mobile-friendly | issues | high | Lighthouse found an anchor without href, and the homepage viewport is hard-coded to width=1210 rather than device width. F26 medium: A login action is not crawlable and homepage mobile metadata is non-responsive |
be-discoverablecanonical-and-indexing-signals | pass | medium | Home and article return 200, expose canonical URLs, index/follow metadata, and robots.txt lists section news sitemaps. |
be-discoverablestructured-and-shareable-metadata | pass | medium | DOM probes found JSON-LD WebSite/Organization on home, two JSON-LD blocks on article, and Open Graph metadata. |
be-private-and-securesecure-transport-and-headers | issues | high | Although HTTPS, HSTS, and frame-ancestors are present, X-Content-Type-Options is missing and all 19 observed cookies were flagged insecure by the primitive; several analytics/consent cookies lack Secure. F27 high: Cookie and response protections are incomplete |
be-private-and-securedata-minimisation-and-third-parties | issues | high | The tracker probe saw 62 third-party origins and 12 known trackers; the HAR attributed 185/192 requests and 2.44MB to non-main origins, while consent copy names 211 partners. F28 critical: The page activates an exceptionally broad tracking surface |
be-private-and-securein-context-permissions-and-modern-auth | issues | high | The homepage sign-in markup exposes email/password fields with no autocomplete tokens and no WebAuthn/passkey signal was observed. F29 medium: The exposed sign-in form lacks modern input/auth affordances |
be-private-and-securedefensive-browser-policies | issues | high | Headers lack Permissions-Policy and nosniff; Referrer-Policy remains no-referrer-when-downgrade, and CSP only specifies frame-ancestors. F30 medium: Defensive browser policies are only partial |
be-resilientprogressive-enhancement | pass | medium | Discoverability captures show 97% home and 89% article word coverage in raw server HTML with title, h1, and description present. |
be-resilientresilient-runtime-behaviour | pass | medium | Representative screenshots, DOM/evaluate probes, and active path inspection found the check outcome satisfied without a conflicting signal. |
be-resilientoffline-and-installable | not-applicable | high | UOL is a continuously updated news service; full offline/installable behavior is not necessary for the audited reading journey, although progressive rendering remains applicable. |
be-resilientnetwork-and-http-failure-states | issues | high | An invalid URL is rewritten to #404 and then renders ordinary homepage content rather than a clear error and recovery state. F31 high: HTTP failure recovery is misleading |
be-internationalisedlang-dir-and-logical-properties | pass | medium | The document declares lang=pt-br and the feature probe found logical CSS properties. |
be-internationalisedlocale-aware-data | pass | medium | Rendered currency uses Brazilian decimal comma and article dates use the expected Brazilian day/month/year format. |
be-internationalisedtime-zone-correctness | pass | medium | Article publication context states São Paulo and presents an unambiguous dated local publication time. |
be-trustworthyno-dark-patterns | issues | high | The first consent layer offers Consent and Manage options, but no equally prominent Reject choice; it describes 211 partners. The homepage fallback says continued browsing is agreement and offers only OK. F32 critical: Consent choice is asymmetric and tracking begins before a clear rejection |
be-trustworthyhumane-error-handling | not-applicable | high | No user-submitted primary form was part of the public reading journey; authentication submission was not attempted with credentials. |
be-trustworthytrustworthy-input-assistance | issues | high | The DOM probe found email and password inputs with empty autocomplete values and no programmatic labels. F33 medium: Sign-in fields omit autocomplete assistance |
be-trustworthysafe-commercial-and-account-flows | not-applicable | high | Checkout, subscription completion, cancellation, and authenticated account management were explicitly outside this public, credential-free audit. |
be-sustainableoptimised-assets | issues | high | Of 100 images, 90 lacked dimensions, 40 lacked srcset, 21 below-fold images were not lazy, and four were oversized. F34 medium: Image delivery misses responsive efficiency basics |
be-sustainableno-wasteful-work | issues | high | Lighthouse estimated 897KiB unused JS and the HAR recorded 64 fetch/XHR requests on initial load. F35 high: The page performs substantial work unrelated to immediate content |
be-sustainablethird-party-and-media-budget | issues | high | Third parties accounted for 185 requests and 2.44MB of 2.61MB transferred; 62 third-party origins were observed. F36 high: Third-party code dominates the page budget |
be-agent-readystructured-agent-capabilities | issues | high | Content is server-rendered (89 to 97 percent crawler coverage), but robots.txt explicitly disallows major agent/search user agents and no structured WebMCP capability is exposed. F37 medium: Public article content is deliberately unavailable to most AI agents |
be-agent-readyon-device-inference | not-applicable | high | Built-in on-device inference is an emerging optional enhancement and is not required to deliver the audited news reading journey. |
be-memory-efficientno-leak-under-repeated-interaction | pass | medium | After 10 full-feed scroll down/up cycles, heap self size rose only 3.6% (61.1MB to 63.3MB) and node count 3.0%, bounded for newly loaded feed content. |
be-memory-efficientbounded-footprint | issues | high | The baseline heap contained 1,318,836 nodes and 61.1MB self size before user interaction, with 236,636 closures. F38 medium: Homepage memory footprint is disproportionate for a news index |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | medium | Before/after heap summaries show modest bounded growth and no Detached constructor among top retained constructors; Promise count decreased. |
