All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | The dark-mode screenshot is visually identical to the light capture, and the CSS probe found no color-scheme declaration or prefers-color-scheme rule. F01 medium: The site does not honour the user’s dark colour-scheme preference. |
respect-user-preferencesrespects-reduced-motion | pass | high | Emulated prefers-reduced-motion: reduce; getAnimations() returned none and the home CSS contains a reduced-motion rule. |
respect-user-preferencesrespects-contrast | pass | high | Forced-colors capture retained visible text, controls, outlines and content with strong system contrast. |
implement-natural-interactionsview-transitions | issues | high | DOM/CSS probes on home, search and product found no view-transition rules; page changes are abrupt full navigations. F02 medium: Route and major state changes do not use View Transitions. |
implement-natural-interactionsscroll-driven-animations | pass | medium | No scroll-linked decorative motion was observed on sampled paths, and probes found no scroll-timeline anti-pattern requiring migration. |
implement-natural-interactionsphysical-gestures | pass | medium | Carousels and standard scrolling remained browser-driven; no sampled core gesture fought native scrolling or required custom pointer handling. |
provide-guided-navigationscroll-state-aware-chrome | issues | high | Desktop and mobile captures show two persistent navigation rows; CSS probes found no scroll-state query or scroll-timeline signal. F03 medium: Dense navigation chrome does not respond to scroll state. |
provide-guided-navigationanchored-positioning | issues | high | The home probe found 27 dialog-role elements and no anchor-name/position-anchor signal; the visible consent surface is a FORM with role=dialog. F04 low: Overlay infrastructure relies on many custom dialog-role containers rather than anchored platform primitives. |
provide-guided-navigationdirects-attention | pass | high | Search/product templates provide breadcrumbs, skip links and clearly labelled result/product destinations. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | At 1440x900 the consent dialog begins around y=437 and occupies the entire lower half; on the product page it covers product details and buying controls. F05 high: The first-load consent surface obscures most primary content. |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | The probe identifies #cos-banner as a FORM with role=dialog, not <dialog>; no aria-modal is present. F06 medium: The consent overlay is not implemented with the native dialog primitive. |
maximize-content-reduce-noisereduced-chrome | issues | high | Desktop captures show two dense navigation rows plus a horizontally clipped card rail; the home page has no single content heading and starts with competing promotional cards. F07 medium: Navigation and merchandising chrome crowd the content. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | The mobile layout primitive reported no viewport meta, a 1000px CSS content width, 360px visual viewport and 640px horizontal overflow; the screenshot shows a clipped desktop canvas. F08 critical: The anonymous home page does not reflow to a 360px viewport. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | high | The home probe found a container-query signal, but search and product probes found none and both use desktop-sized structures without a viewport meta tag. F09 medium: Container-level responsiveness is inconsistent across templates. |
adapt-to-the-form-factorinput-modality-aware | issues | high | Lighthouse failed target-size and found 15px-high footer links; probes counted 13-22 sub-24px targets per template and many focused controls computed outline:none. F10 high: Many controls are too small or lose a visible focus indicator. |
support-core-task-successclear-purpose-and-primary-action | pass | high | Search clearly labels results and product detail exposes title, price, stock and purchase action; empty basket explains its state. |
support-core-task-successprimary-flow-completion | pass | medium | Anonymous search -> listing -> product -> basket/sign-in boundary was reachable without a dead end; order placement was excluded to avoid a transaction. |
support-core-task-successclear-system-state-and-recovery | pass | high | Empty basket gives sign-in/sign-up/deals options and the 404 page explains the failure with a home link. |
be-fast-and-stablegood-core-web-vitals | pass | medium | Trace measured LCP/FCP 1,924ms, one 77ms long task and 27ms TBT; mobile CLS observer measured 0. INP field data was unavailable. |
be-fast-and-stablevisual-stability | issues | high | The image audit found 39 of 40 images missing width/height. Observed CLS was 0 in this capture, but reserved space is absent for late or alternate loads. F11 medium: Images are shipped without intrinsic dimensions, creating avoidable shift risk. |
be-fast-and-stableefficient-main-thread | pass | high | Trace found one long task, longest 77.3ms, with 27.3ms total blocking time over 7.1s. |
be-fast-and-stableefficient-resource-delivery | issues | high | HAR: 131 requests and 2,388,945 transferred bytes, including 739,736 font bytes, 648,982 script bytes, six VeryHigh parser-inserted stylesheets and two parser scripts confirmed without async/defer. F12 medium: The critical path carries many blocking resources and a heavy font/script payload. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | HAR records 26 scripts (648,982 bytes) and 114 third-party-origin requests; a video-card bundle alone transfers 171,088 bytes. F13 medium: JavaScript and third-party delivery are disproportionate for the first viewport. |
be-inclusivenames-roles-labels | issues | high | Lighthouse found invalid aria-expanded on the searchbox, aria-setsize on an incompatible list, and a basket link whose visible “0” is missing from its accessible name. F14 high: Accessible names and ARIA roles are inconsistent. |
be-inclusivesufficient-contrast | pass | high | Lighthouse accessibility score was 0.93 without a colour-contrast failure; forced-colors capture remained legible. |
be-inclusivestructure-and-focus | issues | high | The home has no H1; the product template exposes multiple H1 elements. Probe focus checks found many active controls with outline:none, including navigation and submit controls. F15 high: Heading hierarchy and focus visibility are inconsistent. |
be-inclusivelegible-text | pass | high | Desktop and product screenshots show readable body and heading text with no visible clipping in the sampled desktop condition. |
be-inclusivezoom-reflow-targets-and-media | issues | high | There is no viewport meta tag, the 360px capture retains a 1000px layout, and Lighthouse failed touch-target sizing. F16 high: Mobile reflow and target sizing do not meet an inclusive baseline. |
follow-best-practicesno-console-errors | issues | high | Lighthouse captured a console.error for a late-loading @m/mash module from an Amazon JavaScript resource. F17 medium: The page logs a browser console error on load. |
follow-best-practicessound-document-and-assets | issues | high | Lighthouse found multiple footer images rendered at 1.49 aspect ratio from 2.69-ratio sources; the image audit also found 39 missing intrinsic dimensions. F18 medium: Image asset sizing is unsound. |
follow-best-practicesbrowser-platform-hygiene | issues | high | Lighthouse reports use of the deprecated Shared Storage API from the main document. F19 low: A deprecated browser API remains in use. |
be-discoverabletitle-and-description | issues | high | The search probe found a descriptive title but description:null. Home and product pages do include descriptions. F20 medium: Search result pages omit a meta description. |
be-discoverablecrawlable-and-mobile-friendly | issues | high | Discoverability measured 0% raw-to-rendered content coverage, isJsShell:true, no raw title/H1/description, and a blank crawler screenshot; Lighthouse also found javascript:void(0) links. F21 critical: Non-JavaScript crawlers receive an empty page and some links are not crawlable. |
be-discoverablecanonical-and-indexing-signals | issues | high | Home/product expose canonicals, but search has none, no hreflang links were found, and /sitemap.xml returned 404. F22 high: Indexing signals are incomplete across templates. |
be-discoverablestructured-and-shareable-metadata | issues | high | No JSON-LD was found on home or product; product has no Open Graph tags, while home only exposes og:description. F23 high: Product and home entities lack complete structured/share metadata. |
be-private-and-securesecure-transport-and-headers | issues | high | Headers primitive found no CSP, HSTS, nosniff, frame protection, Referrer-Policy or Permissions-Policy on the main document. Cookie audit found 8/8 flagged, including non-Secure values and session-id cookies without HttpOnly. F24 critical: The main document lacks baseline security headers and sets weak cookies. |
be-private-and-securedata-minimisation-and-third-parties | issues | high | The consent copy names 129 third parties; HAR records 114 third-party-origin requests and 1,889,978 third-party bytes, including ads and telemetry origins. F25 high: The initial page has a broad third-party and advertising footprint. |
be-private-and-securein-context-permissions-and-modern-auth | issues | high | Sign-in exposes username autocomplete but the password input has no current-password token; no passkey/WebAuthn affordance was visible in the anonymous flow. F26 medium: The observed authentication flow does not expose a modern passkey path and password autocomplete is incomplete. |
be-private-and-securedefensive-browser-policies | issues | high | The main response had no clickjacking protection, Referrer-Policy, Permissions-Policy, CSP/Trusted Types policy or HSTS according to the headers primitive. F27 high: Browser-enforced defensive policies are absent on the main document. |
be-resilientprogressive-enhancement | issues | high | Raw HTML was only 2,161 bytes with zero content tokens while the rendered page had 384; browser view was populated and crawler view blank. F28 critical: Core content is unavailable without JavaScript to a plain crawler. |
be-resilientresilient-runtime-behaviour | pass | medium | Sampled search, product, cart and 404 states rendered actionable content; overlays remained attached within the desktop viewport. |
be-resilientoffline-and-installable | not-applicable | high | Amazon retail depends on live price, inventory, identity and checkout state; offline/installability was judged out of scope for this public commerce audit. |
be-resilientnetwork-and-http-failure-states | pass | high | A real 404 returned a concise error explanation and a clear home recovery link rather than a blank shell. |
be-internationalisedlang-dir-and-logical-properties | issues | high | Pages set lang=en-gb, but no dir attribute or hreflang links are present and CSS probes found no logical-property signal on the sampled templates. F29 medium: Locale markup is only partially internationalisation-ready. |
be-internationalisedlocale-aware-data | pass | high | Observed prices use euros and locale formatting (€14.39 displayed as €14 with 39 cents); delivery copy uses a localized weekday/date. |
be-internationalisedtime-zone-correctness | not-applicable | medium | No user-scheduled events or time-zone-sensitive timestamps were present in the representative anonymous shopping journey. |
be-trustworthyno-dark-patterns | pass | medium | Consent offers adjacent Accept and Decline actions without confirmshaming; product price, delivery and stock are visible before basket action. Intrusiveness is reported separately. |
be-trustworthyhumane-error-handling | pass | medium | The sampled sign-in uses a single clearly described email/phone step; basket and 404 recovery states are plain and actionable. Destructive or payment validation was not triggered. |
be-trustworthytrustworthy-input-assistance | issues | high | The observed email field uses autocomplete=username, but the password field returns an empty autocomplete value. F30 medium: The sign-in password field omits the expected autocomplete token. |
be-trustworthysafe-commercial-and-account-flows | pass | medium | Product price, delivery, stock and quantity are visible; basket clearly states it is empty and sign-in is required before protected account work. Transaction submission was not attempted. |
be-sustainableoptimised-assets | issues | high | Image audit: 32 legacy-format images, zero modern-format images, 38 missing srcset, 24 below-fold images not lazy-loaded and 39 missing dimensions. F31 high: Image delivery misses modern responsive optimisation. |
be-sustainableno-wasteful-work | issues | high | HAR includes 131 requests, telemetry beacons and 4 media requests; a 171KB video-card bundle loads on the initial page despite no user interaction. F32 medium: First-load background and media work is not tightly budgeted. |
be-sustainablethird-party-and-media-budget | issues | high | Third-party origins transfer 1.89MB; fonts transfer 739,736 bytes, scripts 648,982 bytes, and media code/resources load before interaction. F33 high: Third-party, font and media costs dominate the page budget. |
be-agent-readystructured-agent-capabilities | issues | high | No WebMCP/modelContext signal was found; robots.txt disallows GPTBot, ClaudeBot, OAI-SearchBot, ChatGPT-User and other agents, while non-JS content coverage is 0%. F34 medium: Commerce capabilities are not exposed safely to agents, and agent crawlers are explicitly blocked. |
be-agent-readyon-device-inference | not-applicable | high | On-device generative inference is not necessary for the representative search, product and basket tasks; absence was not penalised. |
be-memory-efficientno-leak-under-repeated-interaction | pass | medium | After ten menu open/close attempts, heap self size changed from 31.61MB to 31.84MB (+0.23MB, 0.7%) and node count by +776, consistent with bounded variance rather than an unbounded leak. |
be-memory-efficientbounded-footprint | pass | medium | Baseline heap summary was 31.61MB across 461,370 nodes; substantial but proportionate to a large commerce homepage and stable after interaction. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | medium | Before/post heap summaries show no Detached* constructor among top retained constructors and only 0.7% self-size growth after repeated menu interaction. |
