All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	Dark emulation remains visually light and computed color-scheme is normal. f01 medium: The anonymous desktop experience does not follow the system dark-color preference.
respect-user-preferences `respects-reduced-motion`	pass	high	The preference matched and zero active animations were present.
respect-user-preferences `respects-contrast`	pass	medium	Loaded CSS includes forced-colors handling and Lighthouse color-contrast passed; essential UI remains visible in screenshots.
implement-natural-interactions `view-transitions`	issues	high	No view-transition rules are present for cross-document article navigation. f02 low: Cross-document article navigation swaps abruptly.
implement-natural-interactions `scroll-driven-animations`	not-applicable	high	No parallax, scrollytelling, reveal, carousel, or other scroll-linked motion exists to implement. No JS scroll animation anti-pattern was observed.
implement-natural-interactions `physical-gestures`	pass	medium	Reading uses native scrolling and links; no custom pointer handlers, hijacked scrolling, or gestures that fight platform behavior were observed.
provide-guided-navigation `scroll-state-aware-chrome`	issues	high	The article main region is 86,786px tall and no progress or scroll-state CSS was found. f03 low: Very long articles provide no scroll-position progress cue.
provide-guided-navigation `anchored-positioning`	issues	high	Menus are present but no CSS anchor positioning declarations are loaded. f04 low: Menus and transient controls do not use CSS anchor positioning.
provide-guided-navigation `directs-attention`	pass	medium	Current location tabs, article headings/table of contents, language control, and a visible focused skip link provide orientation and attention cues.
maximize-content-reduce-noise `no-intrusive-interruptions`	pass	high	No pop-up, consent wall, ad, or interstitial obscures primary content on load.
maximize-content-reduce-noise `semantic-dismissible-primitives`	issues	high	Mobile main navigation uses a checkbox with role=button rather than a button plus disclosure/popover primitive. f05 medium: The mobile navigation trigger is a checkbox presented as a button instead of a semantic disclosure/popover control.
maximize-content-reduce-noise `reduced-chrome`	pass	high	The anonymous homepage and article prioritize encyclopedia content; chrome is compact and there are no ads.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	issues	high	The desktop response declares width=1120 and is scaled down instead of reflowed. f06 high: The desktop skin fixes its layout viewport at 1120px and scales down at a 360px viewport.
adapt-to-the-form-factor `component-level-responsiveness`	issues	high	No container query rules are present for reused card/navigation components. f07 low: Reusable components rely on page/viewport rules rather than container queries.
adapt-to-the-form-factor `input-modality-aware`	issues	high	Focus is visible, but several article links have target dimensions/separation below 24px. f08 medium: Some article links have touch targets below the recommended minimum.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	The encyclopedia purpose, article title, search/navigation, and login action are explicit and visually prominent.
support-core-task-success `primary-flow-completion`	pass	high	Core content is available without an account and article links are real crawlable hrefs; login has a concise labelled form.
support-core-task-success `clear-system-state-and-recovery`	pass	high	The missing-page state clearly says the article does not exist and offers search, similarly titled pages, help, and creation paths.
be-fast-and-stable `good-core-web-vitals`	issues	high	Article LCP was 6.6s and FCP 4.7s; homepage LCP was 2.42s. f09 high: The representative article loads too slowly under Lighthouse mobile conditions.
be-fast-and-stable `visual-stability`	pass	high	Homepage observed CLS was 0.00043 and article Lighthouse CLS was 0.
be-fast-and-stable `efficient-main-thread`	pass	high	Homepage trace had no long tasks/TBT; article Lighthouse TBT was 83ms.
be-fast-and-stable `efficient-resource-delivery`	issues	high	Script bytes dominate and early parser-inserted resources plus a 328KB script delay the content path. f10 medium: Large startup bundles and blocking styles delay primary content.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Lighthouse estimates 91KiB unused JS and 45KiB unused CSS. f11 medium: The article ships substantial unused JavaScript and CSS.
be-inclusive `names-roles-labels`	issues	high	The article has unnamed images/links and a mis-exposed menu checkbox. f12 high: The article template contains unnamed links/images and an incorrectly exposed menu toggle.
be-inclusive `sufficient-contrast`	issues	high	Inline links fail the non-color distinction requirement against surrounding text. f13 medium: Inline links are distinguished from surrounding prose by color alone with insufficient non-text contrast.
be-inclusive `structure-and-focus`	pass	medium	One H1, hierarchical section headings, main/nav landmarks, a skip link, and a 2px solid visible focus outline were observed.
be-inclusive `legible-text`	pass	medium	Body text has comfortable line-height and content width on the purpose-built mobile article skin; no clipping was reported by Lighthouse.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	Viewport permits scaling and article reflows for mobile UA, but multiple touch targets are too small. f08 medium: Some article links have touch targets below the recommended minimum.
follow-best-practices `no-console-errors`	pass	high	Lighthouse errors-in-console audit passed.
follow-best-practices `sound-document-and-assets`	issues	medium	Doctype/charset are valid and aspect ratios pass, but the homepage has one image missing dimensions and oversized assets. f17 medium: The homepage leaves many below-fold and legacy-format images unoptimized.
follow-best-practices `browser-platform-hygiene`	issues	high	Deprecated API and BFCache audits pass, but Lighthouse reports missing/broken source maps for large first-party scripts and a cookie issue in DevTools. f11 medium: The article ships substantial unused JavaScript and CSS. f15 high: A session-labelled cookie lacks Secure and the CSP permits unsafe script execution modes.
be-discoverable `title-and-description`	issues	high	Titles are descriptive, but meta description is absent on homepage and representative article. f14 medium: Public pages omit a meta description.
be-discoverable `crawlable-and-mobile-friendly`	pass	high	All 659 homepage anchors have hrefs, Lighthouse crawlable-anchors/robots passed, and the mobile article has a viewport meta tag.
be-discoverable `canonical-and-indexing-signals`	pass	high	Pages return 200, homepage has a canonical URL, Lighthouse canonical and hreflang pass, and robots.txt declares the REST sitemap.
be-discoverable `structured-and-shareable-metadata`	pass	medium	Homepage exposes Open Graph tags; MediaWiki articles use semantic headings, image metadata and canonical links consistent with visible content, with no misleading schema found.
be-private-and-secure `secure-transport-and-headers`	issues	high	HTTPS/HSTS/nosniff and no secrets are good, but CSP allows unsafe-inline/unsafe-eval and a session-labelled cookie is not Secure. f15 high: A session-labelled cookie lacks Secure and the CSP permits unsafe script execution modes.
be-private-and-secure `data-minimisation-and-third-parties`	pass	medium	No known tracker domains were found; third-party requests are limited to Wikimedia-operated upload/auth origins and no sensitive secret was exposed.
be-private-and-secure `in-context-permissions-and-modern-auth`	pass	medium	No permission prompt appears on load; login uses username webauthn plus current-password autocomplete, indicating passkey-capable conditional authentication.
be-private-and-secure `defensive-browser-policies`	issues	high	HSTS/nosniff pass, but frame-ancestors/X-Frame-Options, Referrer-Policy and Permissions-Policy are absent. f16 medium: Several browser-enforced defensive policies are absent.
be-resilient `progressive-enhancement`	pass	high	98% of rendered content words are present in raw HTML; title and H1 survive without JavaScript.
be-resilient `resilient-runtime-behaviour`	pass	medium	No uncaught errors or BFCache blocker was detected; navigation and recovery work as documents/links without fragile shell state.
be-resilient `offline-and-installable`	not-applicable	high	No manifest is linked on desktop; anonymous Wikipedia is a public reference content site, not an installed app journey.
be-resilient `network-and-http-failure-states`	pass	high	The missing route produces a clear, content-rich recovery state with search/help/navigation rather than a blank shell.
be-internationalised `lang-dir-and-logical-properties`	pass	high	The document declares lang=fr and dir=ltr and exposes 347 language variants; the UI uses localized French labels.
be-internationalised `locale-aware-data`	pass	medium	Dates, number grouping and interface strings are rendered in French locale conventions across homepage/article UI.
be-internationalised `time-zone-correctness`	not-applicable	high	No booking, scheduling, recurring event, or time-zone-sensitive primary flow exists on the audited templates.
be-trustworthy `no-dark-patterns`	pass	high	No ads, confirmshaming, forced continuity, consent nagging or disguised actions were present; donation/account actions are plainly labelled.
be-trustworthy `humane-error-handling`	pass	medium	Blank login preserves the simple labelled form without blame, and missing content gives specific recovery links and search.
be-trustworthy `trustworthy-input-assistance`	pass	high	Username uses autocomplete="username webauthn" and password uses current-password; both have visible labels.
be-trustworthy `safe-commercial-and-account-flows`	pass	medium	No commercial commitment exists; sign-in is optional for reading, session persistence is an unchecked explicit choice, and help/recovery links are visible.
be-sustainable `optimised-assets`	issues	high	15 below-fold images lack lazy loading; 16 use legacy formats; three are oversized. f17 medium: The homepage leaves many below-fold and legacy-format images unoptimized.
be-sustainable `no-wasteful-work`	issues	high	The anonymous reading path downloads large optional bundles and measurable unused code. f10 medium: Large startup bundles and blocking styles delay primary content. f11 medium: The article ships substantial unused JavaScript and CSS.
be-sustainable `third-party-and-media-budget`	pass	medium	No autoplay audio/video or advertising tracker is present; Wikimedia image/auth origins account for 205,869 third-party bytes and directly support page content/account state.
be-agent-ready `structured-agent-capabilities`	pass	medium	98% raw-HTML content coverage, semantic headings and real hrefs make encyclopedia content reliably machine-readable; MediaWiki also exposes canonical structured endpoints even though no WebMCP tool is declared.
be-agent-ready `on-device-inference`	not-applicable	high	No on-device inference feature is offered or required for the audited reading/login paths.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	medium	JS object count changed 9,582→9,595 and closures 7,942→7,944; growth was concentrated in native objects loaded by scrolling, not accumulating JS state.
be-memory-efficient `bounded-footprint`	pass	medium	Baseline self size was 19.46MB with 241,701 nodes, proportionate to the content-rich homepage; common JS constructors remained modest.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	medium	No Detached* constructor appears among retained constructors; Object and closure populations were effectively stable after ten cycles.
