All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | The desktop and prefers-color-scheme: dark screenshots are pixel-identical at 136,328 bytes and remain white, even though the CSS contains a dark media query and the UI offers a manual appearance setting. F01 medium: The default experience does not follow the system dark-color preference. |
respect-user-preferencesrespects-reduced-motion | pass | high | The media query matched, the stylesheet includes reduced-motion handling, and no active animations were present. |
respect-user-preferencesrespects-contrast | pass | high | Lighthouse passed color contrast and controls/text remained legible in captured templates. |
implement-natural-interactionsview-transitions | issues | high | CSS inspection found no view-transition rules or names on the multi-page reading experience. F02 low: Article and navigation changes are abrupt rather than using cross-document View Transitions. |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No scroll-linked animation exists on the representative templates, so there is no implementation to judge. |
implement-natural-interactionsphysical-gestures | pass | high | Reading uses native scrolling and controls; no custom pointermove gesture layer was found fighting platform behavior. |
provide-guided-navigationscroll-state-aware-chrome | pass | high | The article exposes a persistent contents rail and clear reading chrome without obstructing content; no broken JS scroll toggling was observed. |
provide-guided-navigationanchored-positioning | issues | medium | The article exposes several checkbox-driven dropdown controls, while full stylesheet inspection found no anchor-name, position-anchor, or position-try usage. F03 low: Dropdown and tooltip surfaces do not use CSS anchor positioning. |
provide-guided-navigationdirects-attention | pass | high | Article title, active Read tab, contents rail, section headings and in-page links provide clear location and attention cues. |
maximize-content-reduce-noiseno-intrusive-interruptions | pass | high | No modal, interstitial, consent wall, or content-obscuring banner appeared on load. |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | DOM and axe evidence show role=button checkbox toggles for main, appearance, language and tools menus; the page contains zero popover elements, dialogs, or details. F04 medium: Transient menus are implemented with checkbox inputs rather than popover semantics. |
maximize-content-reduce-noisereduced-chrome | pass | high | The article template gives most of the viewport to readable content with restrained navigation and no advertising chrome. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | At a requested 360x800 viewport, layout reported clientWidth and scrollWidth 1120 with visual scale 0.3214; the mobile screenshot shows tiny text and controls. The viewport meta is width=1120 rather than device-width. F05 high: The desktop experience forces a 1120 CSS-pixel layout at a 360px viewport, shrinking the whole page to unreadable scale. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | high | Full stylesheet inspection found no @container rule, while the narrow-viewport evidence retained the entire 1120px desktop composition. F06 medium: Components do not adapt to available container width. |
adapt-to-the-form-factorinput-modality-aware | issues | high | After programmatically focusing the article search input, computed outline was rgb(32,33,34) none 3px and the only box-shadow was transparent/inset. F07 medium: Keyboard focus on the primary search field is not visibly outlined. |
support-core-task-successclear-purpose-and-primary-action | pass | high | Main, article, search and help templates state their purpose through clear headings and task-specific navigation. |
support-core-task-successprimary-flow-completion | pass | high | The user can enter through Main Page, reach articles/search results, and navigate to help without an account wall. |
support-core-task-successclear-system-state-and-recovery | pass | high | A non-existent title shows a specific explanation plus search, spelling, sister-project, wizard and request alternatives. |
be-fast-and-stablegood-core-web-vitals | pass | high | Lighthouse measured LCP 1.6s, CLS 0 and TBT about 0ms; trace measured LCP 1.167s and no long tasks. |
be-fast-and-stablevisual-stability | pass | high | Article CLS was 0; Main Page CLS was 0.000215 after 3s, both well inside the good range. |
be-fast-and-stableefficient-main-thread | pass | high | Trace found zero long tasks and 0ms TBT; Lighthouse TBT was 2.5ms. |
be-fast-and-stableefficient-resource-delivery | pass | high | The article loaded in 26 requests/434,636 transferred bytes; startup script is async, compression is present, and LCP remained fast. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | Lighthouse estimated 87 KiB unused JavaScript in a 241,047-byte bundle and about 42 KiB unused CSS, including one inline ruleset with 97.2% waste. F08 medium: The reading page ships substantial unused JavaScript and CSS. |
be-inclusivenames-roles-labels | issues | high | axe-core found one critical image-alt violation and five aria-allowed-role violations on the Vector menu checkbox controls. F09 high: The article template includes an image without alternative text and invalid ARIA roles on checkbox menu toggles. |
be-inclusivesufficient-contrast | pass | high | Lighthouse passed color contrast; axe reported only four items requiring manual contrast review, with no confirmed violation. |
be-inclusivestructure-and-focus | pass | high | A main landmark, nav/header/footer structure and ordered visible article headings are present; Lighthouse heading-order passed. |
be-inclusivelegible-text | pass | high | Desktop article and help text use readable line lengths, spacing and stable serif/sans hierarchy. |
be-inclusivezoom-reflow-targets-and-media | pass | high | Lighthouse mobile checks found no media-caption or tap-target failure, and no audio/video is present; scaling is allowed even though narrow reflow is separately deficient. |
follow-best-practicesno-console-errors | pass | high | Lighthouse errors-in-console passed with no items. |
follow-best-practicessound-document-and-assets | pass | high | HTML doctype and UTF-8 charset are present; Lighthouse passed image aspect ratio and responsive image audits. |
follow-best-practicesbrowser-platform-hygiene | pass | high | BFCache passed; no permission prompt appeared on load and no deprecated API failure was reported. |
be-discoverabletitle-and-description | issues | high | The Main Page and Web article probes returned no meta description; Lighthouse scored the meta-description audit 0. F10 medium: Representative public pages omit a meta description. |
be-discoverablecrawlable-and-mobile-friendly | pass | high | Real href links, robots access and raw HTML content are available; Lighthouse passed crawlable anchors, link text and crawlability. |
be-discoverablecanonical-and-indexing-signals | pass | high | Article returns 200 with canonical URL and indexable robots; robots.txt advertises a sitemap endpoint. |
be-discoverablestructured-and-shareable-metadata | pass | high | Article has matching schema.org Article JSON-LD and Open Graph title/type metadata. |
be-private-and-securesecure-transport-and-headers | issues | high | CDP cookie inspection found enwikimwuser-sessionId with secure=false, httpOnly=false and SameSite=None on an HTTPS page. F11 high: A session-identifier cookie is set without Secure or HttpOnly. |
be-private-and-securedata-minimisation-and-third-parties | pass | high | No known trackers or exposed secrets were found; only 9,369 bytes across four third-party requests, all Wikimedia infrastructure. |
be-private-and-securein-context-permissions-and-modern-auth | pass | high | No permission prompt fired on load. Authentication is optional and outside the primary public reading/search journey. |
be-private-and-securedefensive-browser-policies | issues | high | Headers show CSP script-src permits unsafe-inline and unsafe-eval across a very broad host list, with no frame-ancestors directive or X-Frame-Options, Referrer-Policy, or Permissions-Policy. F12 high: Browser-enforced security policy is broad and incomplete. |
be-resilientprogressive-enhancement | pass | high | Raw server HTML retained 97% of rendered content words, title and H1; the page is not a JS shell. |
be-resilientresilient-runtime-behaviour | pass | high | Loaded article/search/help templates remained usable without runtime errors; native document navigation preserves robust baseline behavior. |
be-resilientoffline-and-installable | not-applicable | high | Wikipedia is a public content MPA rather than an installed app; installability is not required for the audited reading journey. |
be-resilientnetwork-and-http-failure-states | pass | high | The missing-title state explains the condition and offers multiple specific recovery paths rather than a blank shell. |
be-internationalisedlang-dir-and-logical-properties | pass | high | The page declares lang=en and dir=ltr, exposes language selection, and stylesheet inspection found logical inline properties. |
be-internationalisedlocale-aware-data | not-applicable | high | The representative disambiguation/help pages expose no locale-sensitive numeric, currency, or duration UI to exercise. |
be-internationalisedtime-zone-correctness | not-applicable | high | The selected templates contain no scheduled event or user-entered time flow where time-zone math applies. |
be-trustworthyno-dark-patterns | pass | high | No ads, consent nag, forced continuity, confirmshaming, or hidden subscription commitment appeared on the public paths. |
be-trustworthyhumane-error-handling | not-applicable | high | No validation-error form flow is part of the public read/search scope; search accepts free text without required-field errors. |
be-trustworthytrustworthy-input-assistance | issues | high | DOM probe found the Search Wikipedia input has autocomplete="off" rather than an appropriate search autocomplete behavior. F13 low: The primary search field explicitly disables browser autocomplete. |
be-trustworthysafe-commercial-and-account-flows | not-applicable | high | No checkout, subscription, authenticated account-management, or sensitive account action was exercised in the public scope. |
be-sustainableoptimised-assets | pass | high | The text article transfers 72,379 image bytes; most chrome assets are SVG and content PNG thumbnails expose srcset. |
be-sustainableno-wasteful-work | pass | high | The trace recorded no long tasks and no continuous media/background activity; the page remains lightweight for its reading purpose. |
be-sustainablethird-party-and-media-budget | pass | high | Only 9,369 third-party bytes were loaded, no known tracker was found, and there is no autoplay audio/video. |
be-agent-readystructured-agent-capabilities | not-applicable | high | The public encyclopedia surfaces content and links, not agent-invokable transactional capabilities; WebMCP tools are not applicable. |
be-agent-readyon-device-inference | not-applicable | high | No on-device inference feature is necessary to complete the encyclopedia reading or search tasks. |
be-memory-efficientno-leak-under-repeated-interaction | pass | medium | After 10 appearance-menu open/close cycles, node count rose only 0.57% (168,312 to 169,276); growth was mostly strings consistent with lazy initialization, not demonstrated unbounded retention. |
be-memory-efficientbounded-footprint | pass | high | Baseline self size was 10.72 MB with 168,312 heap nodes, proportionate for a script-enhanced encyclopedia article. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | Neither baseline nor post top-constructor summaries exposed a Detached* population; jQuery object count remained 16 after 10 menu cycles. |
