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 | Dark preference matched but root color-scheme remained normal and the primary dialog stayed light. F02 medium: The site does not honor the user’s dark color-scheme preference. |
respect-user-preferencesrespects-reduced-motion | pass | high | The emulated preference matched and document.getAnimations() returned no active animations. |
respect-user-preferencesrespects-contrast | pass | high | Text, links, form controls, and focus outlines remained visible in the forced-colors/high-contrast capture. |
implement-natural-interactionsview-transitions | issues | medium | The route capture shows a direct swap and no authored view-transition rule was detected. F03 low: Cross-page navigation swaps views without an authored View Transition. |
implement-natural-interactionsscroll-driven-animations | pass | medium | No scroll-linked decorative effect or main-thread scroll animation was present; ordinary page/document scrolling remained native. |
implement-natural-interactionsphysical-gestures | pass | medium | The covered surfaces use native scrolling and platform controls; no custom pointer-driven gesture that fights scrolling was observed. |
provide-guided-navigationscroll-state-aware-chrome | pass | medium | Persistent header/search and the reader toolbar/page controls keep navigation context visible across long surfaces. |
provide-guided-navigationanchored-positioning | not-applicable | medium | No tooltip, edge menu, or transient popover requiring anchor positioning was exposed in the covered unauthenticated states; the only open overlay was the viewport-fixed consent modal. |
provide-guided-navigationdirects-attention | pass | medium | Category headings, reader page controls, and recovery links make location and the next destination apparent. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | The consent dialog obscures most or all first-load content. F01 high: The consent experience obscures the page on first load, especially on mobile. |
maximize-content-reduce-noisesemantic-dismissible-primitives | pass | high | The consent overlay is labelled role=dialog/aria-modal and exposes close, save, accept, and reject controls with visible focus. |
maximize-content-reduce-noisereduced-chrome | pass | medium | The document reader gives the majority of its central viewport to the document; chrome remains compact and task-related. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | pass | high | Both mobile captures reported scrollWidth=clientWidth=360 with 0px horizontal overflow and a viewport meta tag. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | medium | No container query rules were detected although viewport reflow works. F04 low: Responsive behavior is viewport-driven rather than component-aware. |
adapt-to-the-form-factorinput-modality-aware | issues | high | Several actions computed outline-style none and some targets were below 44×44 CSS pixels. F05 medium: Several controls have weak keyboard focus indication or undersized touch geometry. |
support-core-task-successclear-purpose-and-primary-action | pass | high | Headings and primary controls clearly identify explore/search, read/download, contribute/upload, and create-account purposes. |
support-core-task-successprimary-flow-completion | pass | medium | A category exposes real document hrefs and the selected public document opens in the reader; signup exposes labelled email/password and federated paths. Account-only purchase/download completion was outside the unauthenticated public scope. |
support-core-task-successclear-system-state-and-recovery | pass | high | Native form validity returns actionable messages, polite/assertive live regions exist, and the 404 names the error and links back home/content. |
be-fast-and-stablegood-core-web-vitals | issues | high | Lighthouse LCP was 18.6s and TBT 650ms; the separate trace LCP was 1.90s with 76ms TBT, indicating variable but unacceptable cold-load evidence. F06 high: Cold-load performance is far outside the good user-experience range. |
be-fast-and-stablevisual-stability | pass | high | Observed CLS was 0 on home and 0.0011 on the document, with image dimensions present. |
be-fast-and-stableefficient-main-thread | issues | high | Lighthouse TBT was 650ms; the separate trace recorded one 126ms long task. F20 medium: Cold-load scripting blocks the main thread for too long. |
be-fast-and-stableefficient-resource-delivery | issues | high | The page transferred 2.85MB, including 2.13MB script; HTML was uncompressed and one head script was synchronous. F07 medium: The critical network path includes excessive scripts and an uncompressed document response. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | Lighthouse estimated 905KiB unused JavaScript and 28KiB unused CSS. F08 medium: The landing page ships a large amount of unused JavaScript. |
be-inclusivenames-roles-labels | issues | high | Lighthouse found category card label/content mismatches; axe found no additional violations. F09 medium: Some category links expose accessible names that do not match their visible labels. |
be-inclusivesufficient-contrast | pass | high | axe found no violations, Lighthouse scored accessibility 1.0, and essential UI remained visible in forced colors. |
be-inclusivestructure-and-focus | issues | high | Category accessible-name mismatches and multiple controls with outline-style none prevent a fully reliable focus/name experience. F05 medium: Several controls have weak keyboard focus indication or undersized touch geometry. F09 medium: Some category links expose accessible names that do not match their visible labels. |
be-inclusivelegible-text | pass | high | Body and heading copy uses readable sizing, spacing and wrapping without clipping across covered screenshots. |
be-inclusivezoom-reflow-targets-and-media | issues | high | Reflow succeeds without overflow, but the menu control is 24×40px and consent checkbox boxes are 16×16px. No required media-caption case was present. F05 medium: Several controls have weak keyboard focus indication or undersized touch geometry. |
follow-best-practicesno-console-errors | pass | high | Lighthouse errors-in-console scored 1 with no recorded items. |
follow-best-practicessound-document-and-assets | pass | high | The page uses HTML doctype, UTF-8, correctly proportioned/dimensioned modern-format images, and Lighthouse aspect-ratio audits passed. |
follow-best-practicesbrowser-platform-hygiene | pass | high | Deprecation, BFCache, geolocation/notification-on-load, paste prevention, and source-map audits all scored as passing; security findings are recorded under the dedicated security principle. |
be-discoverabletitle-and-description | pass | high | The homepage has a descriptive title and meta description. |
be-discoverablecrawlable-and-mobile-friendly | issues | high | Links are crawlable and viewport metadata is present, but Lighthouse found two generic Learn more links. F10 low: A small set of links uses generic text. |
be-discoverablecanonical-and-indexing-signals | pass | high | The public page returns 200, declares a canonical, exposes hreflang links, and robots.txt points to locale-specific sitemap indexes without blocking ordinary indexing. |
be-discoverablestructured-and-shareable-metadata | pass | high | The homepage exposes WebSite SearchAction and Organization JSON-LD plus matching og:title, og:description, and og:site_name. |
be-private-and-securesecure-transport-and-headers | issues | high | HTTPS/HSTS and no exposed secrets pass, but CSP, nosniff and cookie hardening are incomplete. F11 high: Important browser security policies and cookie protections are missing. |
be-private-and-securedata-minimisation-and-third-parties | issues | high | 69/72 requests and 2.46MB were non-www origins; five known trackers were active. F12 high: Third-party tracking and integration code dominates the initial load. |
be-private-and-securein-context-permissions-and-modern-auth | issues | medium | No permission prompt occurred on load, but signup offered no passkey/WebAuthn path. F13 medium: Public signup supports password and federated identity but exposes no passkey route. |
be-private-and-securedefensive-browser-policies | issues | high | HSTS is present, but CSP/frame protection, nosniff, Referrer-Policy, Permissions-Policy, and narrow cookie posture are incomplete. F11 high: Important browser security policies and cookie protections are missing. |
be-resilientprogressive-enhancement | pass | high | Raw HTML returned 200 with 100% rendered-content word coverage, the H1 and description present, and no empty JS shell. |
be-resilientresilient-runtime-behaviour | pass | medium | Covered overlays stay within the viewport with scrolling, mobile templates do not overflow, and navigation failures resolve to a recoverable 404. |
be-resilientoffline-and-installable | not-applicable | high | The public website is a server-rendered, network-dependent document marketplace with native apps promoted separately; an offline/installable web-app promise is not part of the covered public experience. |
be-resilientnetwork-and-http-failure-states | pass | high | An unknown route produces a clear Page not found state, explanation, home/content recovery links, and no broken shell. |
be-internationalisedlang-dir-and-logical-properties | issues | high | The advertised Spanish URL delivered English lang/content at the www URL. F14 medium: The advertised Spanish locale target resolves to English content in a fresh browser session. |
be-internationalisedlocale-aware-data | issues | medium | The explicit Spanish target did not preserve the requested locale, so locale-aware delivery could not be established even though hreflang variants are advertised. F14 medium: The advertised Spanish locale target resolves to English content in a fresh browser session. |
be-internationalisedtime-zone-correctness | not-applicable | high | The covered public landing, listing, document, upload, and signup surfaces expose no events, schedules, or user-facing times for which time-zone or DST handling applies. |
be-trustworthyno-dark-patterns | issues | high | All optional advertising/personalisation purposes are checked by default, though a reject-all action is present. F15 medium: Optional consent purposes are preselected by default. |
be-trustworthyhumane-error-handling | pass | high | Empty required fields produce browser-native messages, with dedicated polite/assertive live regions for email and password feedback. |
be-trustworthytrustworthy-input-assistance | pass | high | Email and password are labelled, required, and use autocomplete=email/new-password; newsletter consent is optional and unchecked. |
be-trustworthysafe-commercial-and-account-flows | pass | medium | The public account entry clearly states one subscription for Scribd and Slideshare, offers multiple sign-up methods, and leaves marketing consent off; no sensitive account action was available without authentication. |
be-sustainableoptimised-assets | issues | high | 33/36 images had no srcset and two were oversized, despite modern formats and dimensions. F16 medium: Most images lack responsive source selection. |
be-sustainableno-wasteful-work | issues | high | Initial load fetches large payment, survey, social and duplicate analytics bundles that are not needed for first content. F17 medium: Third-party scripts consume a disproportionate share of page resources. |
be-sustainablethird-party-and-media-budget | issues | high | Third-party origins consumed 2.46MB, including 858KB from Google Tag Manager. F17 medium: Third-party scripts consume a disproportionate share of page resources. |
be-agent-readystructured-agent-capabilities | issues | high | No WebMCP/agentic tools were present and robots explicitly blocks several major AI crawlers. F18 low: Document capabilities are not exposed through structured agent tools, and several major AI crawlers are explicitly blocked. |
be-agent-readyon-device-inference | not-applicable | high | No user-facing summarisation or generative feature is offered in the covered public UI, so built-in on-device inference has no current task to enhance. |
be-memory-efficientno-leak-under-repeated-interaction | pass | medium | Heap self-size changed from 58.29MB to 59.11MB (+1.4%) and nodes from 1,058,563 to 1,069,632 (+1.0%); across isolated captures this is small enough not to establish unbounded retained growth. |
be-memory-efficientbounded-footprint | issues | medium | The two-page reader baseline had 1.06M heap nodes and 58.3MB self-size; post-scroll remained similarly large. F19 medium: The public two-page document viewer starts with a large JavaScript heap graph. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | medium | Neither summary surfaced Detached* constructors among the largest retained constructor groups, and repeated scrolling did not produce a large population jump; intentional caches and isolated-run noise limit confidence. |
