Principle / checkStatusConfidenceEvidence or reason
respect-user-preferences
respects-color-scheme
issueshighUnder prefers-color-scheme: dark, the search page remains white; the probe reports body rgb(255,255,255), color-scheme normal, and no prefers-color-scheme/light-dark() rules in readable CSS.
F001 medium: The storefront ignores the user’s dark colour preference.
respect-user-preferences
respects-reduced-motion
passhighReduced-motion emulation matched and document.getAnimations() returned none while carousel controls remained available.
respect-user-preferences
respects-contrast
issueshighReadable CSS contained no prefers-contrast or forced-colors rules; control visibility therefore relies on the default palette rather than the user preference.
F002 low: No explicit high-contrast or forced-colours adaptation was found.
implement-natural-interactions
view-transitions
passhighReadable CSS contained view-transition rules, providing declarative transition support.
implement-natural-interactions
scroll-driven-animations
passhighReadable CSS contained scroll-timeline and scroll-snap features; trace showed only two modest long tasks rather than sustained scroll-handler work.
implement-natural-interactions
physical-gestures
passhighReadable CSS contained scroll-snap and overscroll-behavior, indicating platform gesture primitives.
provide-guided-navigation
scroll-state-aware-chrome
passhighHomepage CSS includes scroll-timeline support and persistent navigation remains visually anchored across templates.
provide-guided-navigation
anchored-positioning
passhighReadable CSS contained anchor-name, position-anchor, and position-try support.
provide-guided-navigation
directs-attention
passhighSearch terms, result count, headings, selected states, and a 3px keyboard focus outline make destination and focus changes visible.
maximize-content-reduce-noise
no-intrusive-interruptions
passhighNormal homepage and search captures retained access to primary content without a full-viewport modal or consent wall.
maximize-content-reduce-noise
semantic-dismissible-primitives
issueshighThe DOM/CSS probe found 25 role=dialog elements but zero <dialog>, popover, or <details> elements on the homepage.
F003 medium: Overlay implementations rely on custom ARIA dialogs instead of native overlay primitives.
maximize-content-reduce-noise
reduced-chrome
issueshighHomepage, search, and product screenshots show stacked global nav, promotional strips, flyouts, carousels, and tightly packed cards occupying most of the first viewport.
F004 medium: Dense merchandising and navigation chrome competes with product content.
adapt-to-the-form-factor
responsive-no-horizontal-scroll
issueshighAll three audited templates omit meta viewport. At 360x800, the browser uses a 1000 CSS-pixel layout scaled to 0.36; the homepage layout probe also measured 640px overflow.
F005 critical: Desktop pages are scaled down on narrow screens instead of reflowing.
adapt-to-the-form-factor
component-level-responsiveness
passhighReadable CSS contained @container and container-type rules, and product/search cards vary by available region.
adapt-to-the-form-factor
input-modality-aware
issueshighOn the product page, 191 of 228 visible interactive elements were below 44px in at least one dimension; many links were 14–20px high and several controls were 8x4px.
F006 high: Many interactive targets are too small for reliable touch input.
support-core-task-success
clear-purpose-and-primary-action
passhighSearch and product screenshots clearly expose query/results, product title, media, reviews, and purchase controls.
support-core-task-success
primary-flow-completion
blockedhighA complete purchase requires an authenticated account, delivery details, and a real financial transaction. Search-to-product and add-to-cart were attempted, but the cart remained at zero in the anonymous test session; no real order was placed.
support-core-task-success
clear-system-state-and-recovery
passhighEmpty sign-in submission focuses the email field and exposes explicit alert text; WAF recovery offers a Continue shopping action.
be-fast-and-stable
good-core-web-vitals
issueshighLighthouse measured 3.5s LCP and 3.5s FCP; the independent trace measured 2.28s LCP, showing variable but material startup cost.
F007 high: Largest Contentful Paint is outside the good range.
be-fast-and-stable
visual-stability
passhighLayout observers measured CLS 0 on homepage/search and 0.00056 on product.
be-fast-and-stable
efficient-main-thread
passhighTrace measured two long tasks, 86ms maximum, and 48.6ms TBT; mobile layout observers showed only short isolated tasks.
be-fast-and-stable
efficient-resource-delivery
issueshighHAR recorded 108 requests and 2.37MB transferred, including 735KB fonts, 707KB scripts, five very-high-priority parser-inserted stylesheets, and a 291KB WAF challenge script.
F008 high: The homepage has a heavy, render-blocking delivery path.
be-fast-and-stable
trim-unused-and-duplicate-code
issueshighLighthouse estimated 124KiB unused JavaScript and 18KiB unused CSS.
F009 medium: The homepage ships avoidable unused code.
be-inclusive
names-roles-labels
issueshighThe product probe found 42 visible buttons, links, or submit inputs with no text, value, aria-label, or alt-derived name; the image audit also reported missing alt text.
F010 high: The product template exposes visible controls without reliable text alternatives.
be-inclusive
sufficient-contrast
passhighLighthouse accessibility scored 0.96 and reported no colour-contrast failure; visible focus uses a 3px blue outline.
be-inclusive
structure-and-focus
issueshighLighthouse’s landmark-one-main audit failed, and the DOM probe returned no <main> element on the homepage.
F011 medium: The homepage lacks a main landmark.
be-inclusive
legible-text
issueshighAt 360px the product and search templates retain a 1000px layout scaled to 0.36, making body copy, prices, and controls extremely small.
F012 high: Narrow-screen text is rendered as a miniature desktop page.
be-inclusive
zoom-reflow-targets-and-media
issueshighMissing viewport metadata forces desktop-width scaling on all audited templates, while 191/228 product controls fall below 44px in one dimension.
F013 high: The experience fails the reflow and target-size quality bar.
follow-best-practices
no-console-errors
passhighLighthouse best-practices scored 1.0 and its errors-in-console audit did not appear among failing audits.
follow-best-practices
sound-document-and-assets
issueshighThe image audit found 45/46 images without width/height, 32 without srcset, and 45 legacy-format images.
F014 medium: Image delivery lacks dimensions and modern responsive markup.
follow-best-practices
browser-platform-hygiene
passhighLighthouse best-practices scored 1.0, no permission prompt appeared on load, and document probes found standard platform metadata.
be-discoverable
title-and-description
issueshighThe search probe found a descriptive title but no meta[name=description], while homepage and product templates did include descriptions.
F015 medium: Search results lack a meta description.
be-discoverable
crawlable-and-mobile-friendly
issueshighThe homepage probe found prominent javascript:void(0) anchors, and homepage/search/product probes all found no viewport meta tag.
F016 high: Discovery signals include non-crawlable links and no viewport metadata.
be-discoverable
canonical-and-indexing-signals
issueshighThe search results page had no canonical URL, and /sitemap.xml returned HTTP 404; robots.txt otherwise allows ordinary public pages.
F017 medium: Listing/indexing signals are inconsistent.
be-discoverable
structured-and-shareable-metadata
issueshighThe product probe found zero application/ld+json blocks despite visible product, review, and offer content.
F018 medium: The audited product page exposes no JSON-LD product data.
be-private-and-secure
secure-transport-and-headers
issueshighThe headers primitive found HTTPS but no CSP, HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, or Permissions-Policy.
F019 high: Core security headers are absent on the main response observed by Chrome.
be-private-and-secure
data-minimisation-and-third-parties
issueshighTrackers/HAR recorded eight non-main origins and 104/108 requests classified as third-party by origin, including amazon-adsystem and telemetry endpoints; no exposed secrets were found.
F020 medium: The anonymous homepage has a broad telemetry and advertising request surface.
be-private-and-secure
in-context-permissions-and-modern-auth
passhighNo permission prompt appeared on load; sign-in markup contains passkey/WebAuthn support and username autocomplete.
be-private-and-secure
defensive-browser-policies
issueshighNeither CSP/frame-ancestors nor legacy X-Frame-Options was present, and HSTS, Referrer-Policy, and Permissions-Policy were also missing.
F021 high: Browser-enforced defensive policies are not configured.
be-resilient
progressive-enhancement
passhighThe JavaScript-disabled crawler screenshot contains navigation, hero, and merchandising content rather than an empty shell.
be-resilient
resilient-runtime-behaviour
passhighSearch/product controls and dialogs rendered without clipped core content in desktop captures; WAF and sign-in states remained operable.
be-resilient
offline-and-installable
not-applicablehighThe audited commerce transaction is intrinsically online; an offline purchase/installability requirement was not applied, though progressive enhancement was still tested.
be-resilient
network-and-http-failure-states
passhighThe observed WAF/error state explains recovery with a clear Continue shopping button instead of a blank shell.
be-internationalised
lang-dir-and-logical-properties
passhighThe document declares lang=en-au and offers explicit country/language controls; no bidirectional content was present.
be-internationalised
locale-aware-data
passhighThe AU storefront uses en-au, an Australia selector, and Australian-dollar product pricing in search results.
be-internationalised
time-zone-correctness
not-applicablehighNo event scheduling, delivery promise, or other time-zone-sensitive state was available on the audited out-of-stock product and anonymous paths.
be-trustworthy
no-dark-patterns
passhighSampled public pages show offer context, Prime terms, delivery/account state, and conventional navigation without a forced consent wall.
be-trustworthy
humane-error-handling
passhighEmpty sign-in submission focuses the email field and announces “Enter your mobile number or email” through alert containers.
be-trustworthy
trustworthy-input-assistance
passhighSign-in email uses type=email, aria-label, and autocomplete=username; search has an accessible name.
be-trustworthy
safe-commercial-and-account-flows
blockedhighCheckout, cancellation, and account-management completion require authentication and potentially consequential account or financial changes. The public offer and sign-in entry were inspected, but those protected states were not executed.
be-sustainable
optimised-assets
issueshighThe image audit found 45 legacy images, zero modern-format images, 32 without srcset, and 25 below-fold images without lazy loading.
F022 high: Most homepage images use legacy formats without responsive candidates.
be-sustainable
no-wasteful-work
issueshighThe HAR shows 108 requests, including telemetry, ad-system calls, and a 291KB WAF script; 2.08MB of 2.37MB transferred came from non-main origins.
F023 medium: Anonymous loading performs substantial non-content work.
be-sustainable
third-party-and-media-budget
issueshighThe anonymous homepage transfers 2.37MB: 735KB fonts, 522KB images, and 2.08MB from non-main origins before the user acts.
F024 high: Third-party, font, and media weight is disproportionate before interaction.
be-agent-ready
structured-agent-capabilities
issueshighNo WebMCP/agent tool registration was found, while robots.txt disallows GPTBot, ClaudeBot, OAI-SearchBot, ChatGPT-User, and GoogleAgent-Shopping.
F025 low: Agentic commerce capabilities are not exposed and major AI agents are explicitly blocked.
be-agent-ready
on-device-inference
not-applicablehighNo user-facing task in the sampled paths required local generative inference; absence of on-device AI is not itself a defect.
be-memory-efficient
no-leak-under-repeated-interaction
passhighAfter ten hamburger open/close attempts, the in-page probe reported zero heap/DOM delta; independent post heap was smaller than baseline.
be-memory-efficient
bounded-footprint
issueshighThe baseline heap summary contained about 904k heap nodes, 3.39m edges, 54.2MB self size, 66.5k closures, and 6,313 live DOM elements.
F026 medium: The product template has a large in-memory footprint.
be-memory-efficient
no-detached-dom-or-unbounded-listeners
passhighPost-interaction heap totals decreased and no Detached* constructor appeared among the largest retained constructors.
