All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	The prefers-color-scheme: dark screenshot remains white, the computed body surface is rgb(255, 254, 251), and the CSS probe found no prefers-color-scheme, light-dark(), or color-scheme support. F-001 medium: The global and commerce surfaces remain light when the user requests a dark colour scheme.
respect-user-preferences `respects-reduced-motion`	pass	high	Emulated reduced-motion probes found 23 relevant CSS rules on the homepage; article autoplay was disabled, all videos were paused, and no animations ran.
respect-user-preferences `respects-contrast`	pass	high	Forced/high-contrast CSS was present and Lighthouse found no color-contrast failures on either audited template.
implement-natural-interactions `view-transitions`	issues	high	CSS probes on the homepage, article, listing, and product found no view-transition rules or names. F-004 low: Page and route changes do not use View Transitions, so template changes are abrupt.
implement-natural-interactions `scroll-driven-animations`	pass	high	The global templates use animation-timeline/scroll-timeline CSS; no main-thread long tasks were observed during load.
implement-natural-interactions `physical-gestures`	pass	high	CSS probes found scroll-snap and overscroll behavior on editorial and commerce surfaces, with reduced-motion behavior verified.
provide-guided-navigation `scroll-state-aware-chrome`	pass	high	The fixed responsive header and scroll-timeline styles adapt navigation chrome to long pages.
provide-guided-navigation `anchored-positioning`	issues	high	The listing accessibility probe found multiple role=tooltip elements while CSS inspection found no anchor-name, position-anchor, or position-try usage. F-005 low: The listing exposes tooltip overlays but does not use CSS anchor positioning or fallback positions.
provide-guided-navigation `directs-attention`	pass	high	Visible breadcrumbs, category carousels, directional controls, headings, and clear search result counts consistently orient the user.
maximize-content-reduce-noise `no-intrusive-interruptions`	issues	high	Initial desktop, listing, product, and 360x800 screenshots show the consent panel covering the main content. On mobile only the header and consent text/actions are visible. F-002 high: Cookie consent obscures the primary content on every first visit, consuming almost the entire mobile viewport.
maximize-content-reduce-noise `semantic-dismissible-primitives`	issues	high	DOM probes across global and UK pages found a visible DIV role=dialog with no aria-modal and no native dialog element. F-003 medium: The consent modal is an ad-hoc div with role=dialog rather than the platform dialog primitive.
maximize-content-reduce-noise `reduced-chrome`	pass	high	Once consent is set aside, first viewports prioritize imagery, product information, and primary actions with restrained borders.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	pass	high	At 360x800 the homepage and listing both reported scrollWidth equal to clientWidth (360px), viewport meta present, and zero horizontal overflow.
adapt-to-the-form-factor `component-level-responsiveness`	pass	high	CSS probes found container queries on article, listing, and product templates, and mobile screenshots show genuine component reflow.
adapt-to-the-form-factor `input-modality-aware`	issues	high	Lighthouse failed target-size on the global homepage. DOM probes found a 32x28 menu-adjacent button and many 40x40 commerce controls, below a 44x44 target. F-006 medium: Several interactive targets are smaller than the recommended touch target size.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	Homepage, listing, story, search, and product screenshots expose descriptive headings and clear next actions such as Go shopping, search, and Add to shopping bag.
support-core-task-success `primary-flow-completion`	pass	high	A direct search for chair returned 217 products with filters, prices and links; a representative product page exposed price, availability steps, quantity, and add-to-bag action.
support-core-task-success `clear-system-state-and-recovery`	pass	high	Search reports result counts and the invalid-route test showed a clear “Page cannot be found” state with search and homepage recovery paths.
be-fast-and-stable `good-core-web-vitals`	issues	high	Mobile Lighthouse measured LCP at 7.0s on the homepage and 6.2s on the product page. A separate desktop trace measured 1.47s and 2.84s respectively, showing the mobile/throttled path is the risk. F-008 high: Largest Contentful Paint is slow on both the global homepage and product detail template.
be-fast-and-stable `visual-stability`	pass	high	Layout observers reported CLS 0 on homepage and listing; Lighthouse measured CLS 0 and 0.002 on homepage/product.
be-fast-and-stable `efficient-main-thread`	pass	high	Both traces reported zero long tasks and zero total blocking time; Lighthouse also measured TBT 0ms.
be-fast-and-stable `efficient-resource-delivery`	issues	high	The product HAR recorded 246 requests, including 134 scripts and 57 stylesheets, with 1.86MB transferred. Many parser-inserted, VeryHigh-priority stylesheets appear in the critical path; mobile LCP was 6.2s. F-009 high: The commerce product template has a highly fragmented critical resource graph.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Lighthouse estimated 337KiB unused JavaScript and 135KiB unused CSS on the product page; individual bundles were 72% to 99% unused in the measured load. F-010 medium: The product template ships substantial unused JavaScript and CSS.
be-inclusive `names-roles-labels`	issues	high	Lighthouse found visible-label/accessibility-name mismatches on both global and product pages and two malformed list structures on the homepage; the global probe also identified an unnamed visible button. F-007 medium: Accessible names and list semantics are inconsistent on representative pages.
be-inclusive `sufficient-contrast`	pass	high	Lighthouse found zero contrast failures on both tested templates and high-contrast emulation remained legible.
be-inclusive `structure-and-focus`	issues	high	Lighthouse found visible-label/accessibility-name mismatches on both global and product pages and two malformed list structures on the homepage; the global probe also identified an unnamed visible button. F-007 medium: Accessible names and list semantics are inconsistent on representative pages.
be-inclusive `legible-text`	pass	high	Desktop and mobile screenshots show readable type, stable wrapping, strong hierarchy, and no clipping or horizontal overflow.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	Lighthouse failed target-size on the global homepage. DOM probes found a 32x28 menu-adjacent button and many 40x40 commerce controls, below a 44x44 target. F-006 medium: Several interactive targets are smaller than the recommended touch target size.
follow-best-practices `no-console-errors`	issues	high	Lighthouse captured console.error: “[expt-store] exptSDK.init did not return a client” from zip-store-DdpxZMer.js. F-011 low: The product page logs an uncaught experiment-store initialization error.
follow-best-practices `sound-document-and-assets`	issues	high	The images primitive found 15 of 26 product-page images without width/height attributes, including the primary product gallery images. F-012 medium: Many product images omit intrinsic width and height attributes.
follow-best-practices `browser-platform-hygiene`	issues	high	Lighthouse reported six source-map failures, including ratings/reviews and shopping-cart agent bundles. F-013 low: Large first-party scripts have missing or broken source maps.
be-discoverable `title-and-description`	pass	high	Homepage, article, listing, and product probes all found unique descriptive titles and meta descriptions.
be-discoverable `crawlable-and-mobile-friendly`	pass	high	All inspected links had hrefs, viewport metadata was present, robots permits public pages, and Lighthouse SEO was 1.0 on the homepage.
be-discoverable `canonical-and-indexing-signals`	pass	high	Representative pages returned 200, declared index/follow and canonical URLs; the global page exposes extensive hreflang and robots points to a sitemap index.
be-discoverable `structured-and-shareable-metadata`	issues	high	The ASPUDDEN article has useful title, description, canonical and Open Graph image, but no JSON-LD and og:type is website rather than article. F-017 medium: Editorial articles lack article-specific structured data and identify themselves as generic websites in Open Graph.
be-private-and-secure `secure-transport-and-headers`	issues	high	Headers include strong CSP, HSTS, and frame-ancestors, but omit X-Content-Type-Options, Referrer-Policy, and Permissions-Policy. The cookies primitive found OptanonConsent set without Secure. F-014 medium: Several browser-enforced security and privacy policies are absent, and one consent cookie is not Secure.
be-private-and-secure `data-minimisation-and-third-parties`	pass	high	Before optional consent, the tracker probe found only two consent-management origins and no known tracker match; third-party transfer was 157KB on the homepage.
be-private-and-secure `in-context-permissions-and-modern-auth`	pass	high	Geolocation and notifications remained in prompt state rather than being requested on load. Login uses OAuth2 PKCE and defaults to an emailed one-time code rather than password-only authentication.
be-private-and-secure `defensive-browser-policies`	issues	high	Headers include strong CSP, HSTS, and frame-ancestors, but omit X-Content-Type-Options, Referrer-Policy, and Permissions-Policy. The cookies primitive found OptanonConsent set without Secure. F-014 medium: Several browser-enforced security and privacy policies are absent, and one consent cookie is not Secure.
be-resilient `progressive-enhancement`	pass	high	Raw HTML retained 75% of homepage and 82% of product content; neither was a JS shell, with title and descriptions available without JS.
be-resilient `resilient-runtime-behaviour`	pass	high	Long listing/product templates rendered without horizontal overflow or cut-off core controls; CSS includes container queries, scroll snap, overscroll and logical properties.
be-resilient `offline-and-installable`	issues	high	Homepage, listing, and product probes found no web app manifest and no controlling service worker. The commerce journey depends on networked fragments. F-015 medium: The app-like commerce experience is neither installable nor equipped with an offline fallback.
be-resilient `network-and-http-failure-states`	pass	high	The tested invalid route renders an explicit, actionable recovery page instead of a blank shell or infinite spinner.
be-internationalised `lang-dir-and-logical-properties`	pass	high	Pages declare en/en-GB and ltr correctly, global hreflang variants are extensive, and probes found logical CSS properties.
be-internationalised `locale-aware-data`	pass	high	The UK product and search templates render locale-appropriate pounds, decimal prices and en-GB language while global hreflang routes expose localized alternatives.
be-internationalised `time-zone-correctness`	not-applicable	high	The representative pages contain no event scheduling or time-zone-sensitive values to evaluate.
be-trustworthy `no-dark-patterns`	pass	high	Consent offers equally prominent accept and reject actions; product price, previous price, discount, and availability requirements are explicit.
be-trustworthy `humane-error-handling`	pass	high	Search succeeds without unnecessary required fields, and the tested invalid route explains the problem without blame and offers recovery.
be-trustworthy `trustworthy-input-assistance`	pass	high	The representative search field has a programmatic label, search input type, and predictable GET action; no paste prevention was observed.
be-trustworthy `safe-commercial-and-account-flows`	pass	high	Product pricing, quantity, availability, returns reassurance, and add-to-bag are visible; account login uses a one-time-code default and OAuth2 PKCE.
be-sustainable `optimised-assets`	issues	high	The images primitive classified 39 of 40 images as JPG/PNG/GIF, found seven below-fold images without lazy loading and six oversized images. Lighthouse measured a 2.51MiB page load. F-016 medium: The global editorial homepage relies heavily on legacy image formats and eagerly starts some below-fold media.
be-sustainable `no-wasteful-work`	pass	high	Despite asset issues, traces found no long tasks or ongoing main-thread blocking, and third-party activity before consent was limited to consent management.
be-sustainable `third-party-and-media-budget`	issues	high	The images primitive classified 39 of 40 images as JPG/PNG/GIF, found seven below-fold images without lazy loading and six oversized images. Lighthouse measured a 2.51MiB page load. F-016 medium: The global editorial homepage relies heavily on legacy image formats and eagerly starts some below-fold media.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	No declared agent-facing scope was found; this emerging WebMCP capability is an opportunity, not a requirement for the inspected public pages.
be-agent-ready `on-device-inference`	not-applicable	high	The inspected retail and editorial tasks do not require on-device generative inference; absence is not a user-facing failure.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	high	After ten full listing scroll cycles, heap self-size rose only 108,228 bytes (0.3%); object, array, and closure counts decreased rather than accumulating.
be-memory-efficient `bounded-footprint`	pass	high	The content-heavy listing retained about 35.3MB in the heap summary, proportionate to its 103-image, multi-section template.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	The post-interaction summary showed only +252 nodes, lower object/array/closure populations, and no Detached* constructor among top retained constructors.
