All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | Under prefers-color-scheme: dark, the screenshot remains light and the probe reports colorScheme "normal" with a white body background. F003 medium: The site ignores the user’s dark color-scheme preference. |
respect-user-preferencesrespects-reduced-motion | issues | high | The reduced-motion probe found five running shape-flow animations, each with a 20,000 ms duration, while prefers-reduced-motion: reduce matched. F004 medium: Long-running decorative motion continues under reduced motion. |
respect-user-preferencesrespects-contrast | pass | high | Lighthouse color-contrast passed; prefers-contrast emulation matched and the live CSS included contrast rules. |
implement-natural-interactionsview-transitions | issues | high | The platform-feature CSS probe found no view-transition rules across the representative category interface. F005 low: Page and state changes do not use declarative View Transitions. |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No scroll-linked animation was present on the audited templates, so implementation technique does not apply. |
implement-natural-interactionsphysical-gestures | not-applicable | high | No swipe, pull, carousel gesture, or other gesture-driven core control was present in the audited public paths. |
provide-guided-navigationscroll-state-aware-chrome | issues | medium | The 4,991 px category page screenshot and CSS probe show a static desktop header with no scroll-state or scroll progress treatment. F006 low: The long catalog lacks scroll-state-aware navigation cues. |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip or edge-positioned popover was required in the exercised category and search states. |
provide-guided-navigationdirects-attention | pass | high | The category breadcrumb, selected category, product count, and product headings provide explicit orientation. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | Desktop and mobile screenshots after a 5 second wait show a large Accio Work trial modal dimming and blocking the primary Alibaba marketplace content. F001 high: A promotional trial interstitial obscures the homepage on arrival. |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | medium | The homepage DOM snapshot taken while the overlay was visible contained no <dialog> or popover element, while the screenshot shows modal behavior. F002 medium: The load-time overlay is not exposed through a native modal primitive in the captured DOM. |
maximize-content-reduce-noisereduced-chrome | issues | high | At 360 px the fixed desktop filter rail occupies most of the visible width, leaving only a clipped product column. F007 medium: Dense persistent filters and navigation crowd the product content. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | Layout evidence reports scrollWidth 1200, clientWidth 360, and 840 px horizontal overflow; the screenshot shows clipped header, breadcrumb, filters, and products. F008 critical: The category template renders a 1,200 px desktop layout on a 360 px viewport. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | high | The category’s filter/product composition remains desktop-sized at 360 px, and the platform CSS probe found no container-query rules. F009 high: Catalog components do not adapt to their available container. |
adapt-to-the-form-factorinput-modality-aware | issues | high | Lighthouse found 35 target-size failures; the focus probe found many anchors with outline-style none and no box shadow. F010 high: Many controls are too small and several links have no visible focus indicator. |
support-core-task-successclear-purpose-and-primary-action | pass | high | The category first viewport clearly names “Solar Panels”, product count, filters, products, prices, MOQ, and search. |
support-core-task-successprimary-flow-completion | issues | high | Fresh search, manufacturer, and product-detail captures all returned “Captcha Interception” and a slide-to-verify challenge instead of results or product content. F011 high: Search, manufacturer, and product-detail navigation can dead-end at an anti-bot challenge. |
support-core-task-successclear-system-state-and-recovery | issues | high | The challenge shows only a slider, QR code, and “Click to feedback”; it does not explain how to resume the search or preserve the query. F012 medium: The traffic challenge provides weak recovery and no path back to the intended task. |
be-fast-and-stablegood-core-web-vitals | issues | high | The raw trace measured homepage LCP at 5,256.64 ms. Category Lighthouse measured 2.1 s, showing a template-specific regression. F013 high: Homepage LCP is slow despite the category template performing well. |
be-fast-and-stablevisual-stability | pass | high | Mobile category layout recorded CLS 0.00015; category Lighthouse CLS was 0.00013. |
be-fast-and-stableefficient-main-thread | pass | high | Homepage trace total blocking time was 80.1 ms and category Lighthouse TBT was 67 ms. |
be-fast-and-stableefficient-resource-delivery | issues | high | HAR evidence records 465 requests and 7,776,049 transferred bytes, including 102 scripts (3.60 MB), 222 images (1.61 MB), and multiple parser-inserted stylesheets. F014 high: The homepage ships a very large request graph. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | The HAR shows large messenger/RFQ bundles on homepage load; Lighthouse found 44 KiB unused in one category bundle (72.7% of that resource). F015 medium: Non-critical and partly unused JavaScript is shipped up front. |
be-inclusivenames-roles-labels | issues | high | Lighthouse failed button-name and link-name; the DOM probe counted 114 empty links and 78 images without an alt attribute on the category page. F016 high: Important controls and links lack accessible names. |
be-inclusivesufficient-contrast | pass | high | Lighthouse color-contrast audit passed on the category template. |
be-inclusivestructure-and-focus | issues | high | Lighthouse failed landmark-one-main; focus sampling found many anchors with no outline or focus shadow. F017 high: The category page has no main landmark and focus styling is inconsistent. |
be-inclusivelegible-text | pass | high | Desktop/category screenshots show readable type hierarchy and Lighthouse found no contrast failure. |
be-inclusivezoom-reflow-targets-and-media | issues | high | At 360 px the category overflows by 840 px and Lighthouse reports 35 undersized or crowded targets. F018 high: The interface fails narrow reflow and target-size requirements. |
follow-best-practicesno-console-errors | issues | high | Lighthouse captured TypeError: Cannot read properties of null (reading “2”) in cdn-seo-ai-category-wap/index.js. F019 medium: A category JavaScript exception is logged. |
follow-best-practicessound-document-and-assets | issues | high | The image primitive found all three visible images without width/height, two without srcset, and one 600 px image displayed at 134 px. F020 medium: Image delivery lacks basic sizing and responsive hints in the observed homepage overlay. |
follow-best-practicesbrowser-platform-hygiene | issues | high | Lighthouse reports an unload listener and four BFCache failure reasons, plus a deprecated API warning. F021 medium: Deprecated unload behavior prevents BFCache restoration. |
be-discoverabletitle-and-description | pass | high | Homepage and category expose descriptive titles and meta descriptions in raw and rendered HTML. |
be-discoverablecrawlable-and-mobile-friendly | pass | high | Lighthouse SEO scored 1.0; anchors are crawlable and category viewport metadata is valid, notwithstanding the separate reflow failure. |
be-discoverablecanonical-and-indexing-signals | pass | high | Category returned 200 with canonical URL, index/follow robots meta; robots.txt and sitemap.xml returned 200. |
be-discoverablestructured-and-shareable-metadata | issues | high | Metadata evidence shows complete Open Graph tags but no JSON-LD for the product-list/category entity. F022 low: The category has social metadata but no structured entity data. |
be-private-and-securesecure-transport-and-headers | issues | high | The HTTPS response has no CSP, HSTS, nosniff, frame protection, Referrer-Policy, or Permissions-Policy; two 180-day cookies are not Secure and use SameSite=None. F023 high: Baseline security headers and cookie protections are missing. |
be-private-and-securedata-minimisation-and-third-parties | issues | high | HAR reports 461 of 465 requests and 7.74 of 7.78 MB as third-party by origin, while tracker evidence enumerates 12 third-party origins. F024 high: Nearly the entire homepage transfer is attributed to cross-origin infrastructure and telemetry-heavy dependencies. |
be-private-and-securein-context-permissions-and-modern-auth | pass | high | Login loaded without permission prompts and offered Google, Facebook, LinkedIn, QR, and email routes; passkey-related capability text was present in the document probe. |
be-private-and-securedefensive-browser-policies | issues | high | Header evidence confirms no CSP/frame-ancestors or X-Frame-Options, HSTS, Referrer-Policy, or Permissions-Policy. F025 high: Browser-enforced defense policies are absent. |
be-resilientprogressive-enhancement | issues | high | Discoverability measured 44% homepage and 47% category content coverage without JavaScript. The pages are not empty shells, but substantial product/content detail depends on client rendering. F026 medium: Only about half of rendered catalog vocabulary is available in raw HTML. |
be-resilientresilient-runtime-behaviour | pass | high | The successfully loaded category remained functional and stable with native navigation and no clipped overlay in the desktop state. |
be-resilientoffline-and-installable | not-applicable | high | Alibaba is a transaction marketplace whose current inventory, identity, and ordering require a live connection; an installable/offline app shell was judged non-essential for the audited public web scope. |
be-resilientnetwork-and-http-failure-states | pass | high | The anti-bot response rendered a stable explanatory state and feedback route rather than a blank shell; task recovery limitations are recorded separately. |
be-internationalisedlang-dir-and-logical-properties | pass | high | Category HTML declares lang=en; captured CSS uses inset-inline-start/end and the page exposes region/language selection. |
be-internationalisedlocale-aware-data | pass | high | The page selected delivery region GB and presents explicit currency-valued product prices rather than ambiguous bare numbers. |
be-internationalisedtime-zone-correctness | not-applicable | high | The representative public pages showed no dates, events, schedules, or time-zone-sensitive data. |
be-trustworthyno-dark-patterns | pass | high | The observed promotion has a visible close control and no confirmshaming; listings expose price and MOQ. |
be-trustworthyhumane-error-handling | pass | high | The only exercised exceptional state explains unusual traffic and offers feedback; its weak recovery is recorded under core task success. |
be-trustworthytrustworthy-input-assistance | pass | high | Search has an accessible label; login identifies the email input and offers QR/social alternatives, though autocomplete is off. |
be-trustworthysafe-commercial-and-account-flows | pass | high | Public listings show price and MOQ; login offers multiple routes without requesting payment or hidden commitment. |
be-sustainableoptimised-assets | issues | high | Image evidence found an oversized 600 px PNG displayed at 134 px and missing responsive sources; the homepage transferred 1.61 MB across 222 images. F027 medium: Image assets are not consistently right-sized or responsive. |
be-sustainableno-wasteful-work | issues | high | The homepage HAR includes 600 KB messenger, 554 KB chat, and 465 KB RFQ bundles during initial load. F028 high: Large messaging and RFQ modules load before user intent. |
be-sustainablethird-party-and-media-budget | issues | high | The homepage transfers 7.78 MB across 465 requests, with 7.74 MB attributed to origins outside www.alibaba.com. F029 high: The initial page budget is disproportionate to the marketplace landing task. |
be-agent-readystructured-agent-capabilities | issues | high | The homepage advertises “AI Mode”, but the platform probe found no WebMCP/agent tool registration; Lighthouse agentic-browsing scored 0.33. F030 low: The marketplace exposes no structured agent tools despite an explicit AI-oriented sourcing surface. |
be-agent-readyon-device-inference | not-applicable | high | No summarisation or generative task requiring local inference was exposed in the audited public flow. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | After ten filter toggle cycles, heap self-size decreased from 33,646,286 to 33,549,660 bytes and node count decreased from 444,025 to 443,111. |
be-memory-efficientbounded-footprint | pass | high | The category heap was 33.6 MB self-size for a dense 530-image catalog page, proportionate to the rendered surface. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | Post-interaction heap totals did not grow and no Detached* constructor appeared among the largest constructor populations. |
