All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	The dark-condition screenshot remains the same white/light-blue theme as the default, and the DOM/CSS probe found no adaptive dark surface behavior. F003 medium: The portal does not adapt its visual theme to the user’s dark color-scheme preference.
respect-user-preferences `respects-reduced-motion`	pass	high	Under prefers-reduced-motion: reduce, matchMedia matched and getAnimations() returned no active animations.
respect-user-preferences `respects-contrast`	pass	high	Lighthouse accessibility audit passed the color-contrast checks on the sampled homepage.
implement-natural-interactions `view-transitions`	issues	high	The CSS probe found zero view-transition rules and the MPA navigation has no transition affordance. F005 low: Primary page/state changes do not use view transitions.
implement-natural-interactions `scroll-driven-animations`	pass	high	CSS/runtime probe found no custom animation timeline or scroll animation; scrolling remains browser-native with no main-thread scroll animation anti-pattern.
implement-natural-interactions `physical-gestures`	pass	high	The sampled portal uses native page scrolling and ordinary controls; no pointermove-driven gesture replacement or scroll-jacking was observed.
provide-guided-navigation `scroll-state-aware-chrome`	issues	medium	The 5,474 px mobile homepage uses conventional static chrome; the platform probe found no scroll-timeline rules and screenshots show no progress or section cue. F004 low: Long portal pages provide no scroll-progress or scroll-state-aware navigation cue.
provide-guided-navigation `anchored-positioning`	pass	high	No tooltip/menu overlay requiring anchored edge positioning appears in the primary content; ordinary navigation remained aligned at tested viewports.
provide-guided-navigation `directs-attention`	pass	high	Screenshots show a clear portal title, hero/news area, and labeled service cards that direct users to the main tasks.
maximize-content-reduce-noise `no-intrusive-interruptions`	issues	high	Desktop and 360 px screenshots show a fixed, dimming consent layer covering roughly half the viewport before any interaction; on mobile it blocks the article and primary service cards. F001 high: The cookie consent layer obscures the primary content on every gov.br template tested.
maximize-content-reduce-noise `semantic-dismissible-primitives`	issues	high	The platform probe found one full-width fixed .br-cookiebar but zero dialog, popover, or details elements; screenshots show modal-like behavior. F002 medium: The blocking cookie layer is a custom fixed div rather than a semantic dialog or popover.
maximize-content-reduce-noise `reduced-chrome`	issues	high	Desktop and 360 px screenshots show a fixed, dimming consent layer covering roughly half the viewport before any interaction; on mobile it blocks the article and primary service cards. F001 high: The cookie consent layer obscures the primary content on every gov.br template tested.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	pass	high	Layout at 360×800 measured scrollWidth 360, clientWidth 360, and 0 px horizontal overflow on both homepage and consultation.
adapt-to-the-form-factor `component-level-responsiveness`	pass	high	Homepage and form components reflow to 360 px without horizontal overflow; mobile screenshots show stacked cards/fields.
adapt-to-the-form-factor `input-modality-aware`	issues	high	The focus/target probe measured the menu at 28×28 px and several social/icon links at roughly 19–33 px; mobile screenshots show dense floating accessibility controls over content. F019 medium: Several primary interactive targets are smaller than recommended touch dimensions.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	The H1 identifies the NFS-e portal and prominent cards expose Emitir Nota Fiscal, Consultar Nota Fiscal, municipality and documentation tasks.
support-core-task-success `primary-flow-completion`	issues	high	All business fields report required=false despite visible asterisks; clicking submit at 360 px leaves the page at the form/captcha with no visible field-specific errors in the captured state. F006 high: The public consultation form does not expose native required-state or usable invalid-submit feedback.
support-core-task-success `clear-system-state-and-recovery`	issues	high	All business fields report required=false despite visible asterisks; clicking submit at 360 px leaves the page at the form/captcha with no visible field-specific errors in the captured state. F006 high: The public consultation form does not expose native required-state or usable invalid-submit feedback.
be-fast-and-stable `good-core-web-vitals`	issues	high	Trace measured FCP 5.69 s and LCP 12.03 s; Lighthouse measured mobile LCP 23.3 s with performance 0.49; HAR recorded 13,419,727 transferred bytes, including 11,020,326 image bytes and individual PNGs up to 2.21 MB. F007 high: Homepage loading is very slow and transfers 13.4 MB, mostly oversized PNG imagery.
be-fast-and-stable `visual-stability`	issues	high	Lighthouse measured CLS 0.144 and identified five layout-shift culprits, although the short post-load layout observer measured 0 after settling. F008 medium: The homepage is not visually stable during a throttled mobile load.
be-fast-and-stable `efficient-main-thread`	pass	high	Trace found one 87.81 ms long task and only 37.81 ms total blocking time; the dominant delay is network/media rather than sustained main-thread blocking.
be-fast-and-stable `efficient-resource-delivery`	issues	high	Trace measured FCP 5.69 s and LCP 12.03 s; Lighthouse measured mobile LCP 23.3 s with performance 0.49; HAR recorded 13,419,727 transferred bytes, including 11,020,326 image bytes and individual PNGs up to 2.21 MB. HAR recorded 19 stylesheets, 28 scripts and 16 fonts; Lighthouse flagged three large first-party scripts without valid source maps; Swiper 3.4.2 is loaded from a third-party CDN. F007 high: Homepage loading is very slow and transfers 13.4 MB, mostly oversized PNG imagery. F009 medium: The page ships a fragmented, partly legacy resource graph.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	HAR recorded 19 stylesheets, 28 scripts and 16 fonts; Lighthouse flagged three large first-party scripts without valid source maps; Swiper 3.4.2 is loaded from a third-party CDN. F009 medium: The page ships a fragmented, partly legacy resource graph.
be-inclusive `names-roles-labels`	issues	high	Lighthouse found one unnamed button and seven links without discernible names, plus a visible-label/accessibility-name mismatch; the focus probe also recorded multiple visible links with empty text. The consultation probe found an empty html lang, zero headings, and no associated labels for the main text/select controls; its first visual content begins directly with a fieldset-like block. F010 high: Interactive controls and links lack accessible names. F011 high: The consultation form lacks basic document and form structure.
be-inclusive `sufficient-contrast`	pass	high	Lighthouse accessibility score was 0.92 and did not report a color-contrast failure.
be-inclusive `structure-and-focus`	issues	high	Lighthouse found one unnamed button and seven links without discernible names, plus a visible-label/accessibility-name mismatch; the focus probe also recorded multiple visible links with empty text. The consultation probe found an empty html lang, zero headings, and no associated labels for the main text/select controls; its first visual content begins directly with a fieldset-like block. F010 high: Interactive controls and links lack accessible names. F011 high: The consultation form lacks basic document and form structure.
be-inclusive `legible-text`	pass	high	Article and portal screenshots show readable text sizing, line spacing, and left alignment at desktop and 360 px.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	The focus/target probe measured the menu at 28×28 px and several social/icon links at roughly 19–33 px; mobile screenshots show dense floating accessibility controls over content. F019 medium: Several primary interactive targets are smaller than recommended touch dimensions.
follow-best-practices `no-console-errors`	pass	high	Lighthouse best-practices scored 1.0 and reported no runtime console-error audit failure.
follow-best-practices `sound-document-and-assets`	issues	high	HAR recorded 19 stylesheets, 28 scripts and 16 fonts; Lighthouse flagged three large first-party scripts without valid source maps; Swiper 3.4.2 is loaded from a third-party CDN. F009 medium: The page ships a fragmented, partly legacy resource graph.
follow-best-practices `browser-platform-hygiene`	issues	high	HAR recorded 19 stylesheets, 28 scripts and 16 fonts; Lighthouse flagged three large first-party scripts without valid source maps; Swiper 3.4.2 is loaded from a third-party CDN. F009 medium: The page ships a fragmented, partly legacy resource graph.
be-discoverable `title-and-description`	issues	high	The platform probe returned description:null and Lighthouse failed the meta-description SEO audit; article pages do include descriptions. F012 medium: The homepage has no meta description.
be-discoverable `crawlable-and-mobile-friendly`	pass	high	Raw HTML contains the H1/title and descriptive href links; both main templates have viewport metadata and mobile layouts have no overflow.
be-discoverable `canonical-and-indexing-signals`	pass	high	Homepage has a canonical URL; robots.txt permits this section and advertises a sitemap; the section sitemap returned 200 with current article URLs.
be-discoverable `structured-and-shareable-metadata`	pass	high	Homepage probe found two JSON-LD blocks and seven Open Graph properties; the article content and title are present in raw HTML.
be-private-and-secure `secure-transport-and-headers`	pass	high	HTTPS is used and the final document headers include HSTS, nosniff, X-Frame-Options DENY, referrer policy, and frame-ancestors CSP.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	Tracker/HAR capture found seven third-party origins and 84 of 86 requests classified cross-origin from the requested host, totaling 13.42 MB; no known analytics tracker was detected. F018 medium: The page relies on a large third-party delivery footprint even before consent.
be-private-and-secure `in-context-permissions-and-modern-auth`	pass	high	No permission prompt fired on load; account entry is a clearly labeled gov.br sign-in rather than an unsolicited permission flow.
be-private-and-secure `defensive-browser-policies`	issues	high	The final gov.br document response includes HTTPS, HSTS, nosniff, X-Frame-Options DENY, strict-origin-when-cross-origin and CSP frame-ancestors, but the CSP does not restrict script/style sources and no Permissions-Policy was observed. F013 medium: Security policy headers are only partially defensive.
be-resilient `progressive-enhancement`	pass	high	Discoverability measured 83% raw/rendered word coverage for homepage and article, 100% for consultation, with no empty SPA shell.
be-resilient `resilient-runtime-behaviour`	pass	high	Server-rendered navigation and consultation form remained usable at desktop and 360 px with no horizontal overflow or runtime error.
be-resilient `offline-and-installable`	not-applicable	high	This informational portal and public lookup were not presented as installable/offline products; offline installation is contextual and not necessary to the audited purpose.
be-resilient `network-and-http-failure-states`	pass	high	The deliberate missing route shows a Portuguese error H1, explanation, support link, and direct home recovery link.
be-internationalised `lang-dir-and-logical-properties`	issues	high	The consultation DOM probe returned an empty html lang while the gov.br content templates correctly use pt-br. F014 medium: The standalone consultation application does not declare its content language.
be-internationalised `locale-aware-data`	not-applicable	high	The sampled surfaces contain no locale-sensitive currency, numeric, duration, or calendar formatting requiring an alternate locale.
be-internationalised `time-zone-correctness`	not-applicable	high	The sampled surfaces do not coordinate user-specific events or display time-zone-sensitive timestamps.
be-trustworthy `no-dark-patterns`	pass	high	Cookie choices present Reject and Accept with equal visual weight and a separate manage option; no confirmshaming or preselected paid choice was observed.
be-trustworthy `humane-error-handling`	issues	high	All business fields report required=false despite visible asterisks; clicking submit at 360 px leaves the page at the form/captcha with no visible field-specific errors in the captured state. F006 high: The public consultation form does not expose native required-state or usable invalid-submit feedback.
be-trustworthy `trustworthy-input-assistance`	issues	high	The consultation probe found empty autocomplete values on all business inputs, generic text input types, and no native required constraints. F015 medium: Consultation fields provide little browser-native input assistance.
be-trustworthy `safe-commercial-and-account-flows`	pass	high	No commercial checkout exists; sign-in is clearly delegated to gov.br and no hidden subscription or payment commitment appears.
be-sustainable `optimised-assets`	issues	high	HAR attributes 11.02 MB to 16 images, with seven PNG/JPEG assets between 0.83 MB and 2.21 MB; total transfer is 13.42 MB for a mostly informational landing page. F016 high: Image delivery is far beyond a proportionate sustainability budget.
be-sustainable `no-wasteful-work`	pass	high	Trace showed low total blocking time and no evidence of autoplay media or persistent idle/background processing in the sampled load.
be-sustainable `third-party-and-media-budget`	issues	high	HAR attributes 11.02 MB to 16 images, with seven PNG/JPEG assets between 0.83 MB and 2.21 MB; total transfer is 13.42 MB for a mostly informational landing page. Tracker/HAR capture found seven third-party origins and 84 of 86 requests classified cross-origin from the requested host, totaling 13.42 MB; no known analytics tracker was detected. F016 high: Image delivery is far beyond a proportionate sustainability budget. F018 medium: The page relies on a large third-party delivery footprint even before consent.
be-agent-ready `structured-agent-capabilities`	issues	medium	The DOM/probe found conventional HTML links/forms but no WebMCP registration or agentic tool metadata; the consultation is a meaningful public task that agents could assist with while preserving confirmation and captcha boundaries. F017 medium: Public service capabilities are not exposed in a structured agent-readable form.
be-agent-ready `on-device-inference`	not-applicable	high	No summarization, generation, or other AI feature is part of the portal’s stated task, so on-device inference is not applicable.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	high	After ten next/previous carousel cycles, heap size fell from 28,773,165 to 28,678,406 bytes and node count fell from 458,491 to 458,297, showing no retained-growth signal.
be-memory-efficient `bounded-footprint`	pass	high	Baseline heap was 28.77 MB for a media-rich portal; despite excessive network image bytes, live JS heap remained bounded and proportionate.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	The repeated-interaction heap did not grow in nodes, closures, arrays, or total self size; no detached-DOM growth signal appeared in the summaries.
