adapt-to-the-form-factor `component-level-responsiveness`	issues	high	Rendered DOM/CSS inspection of the homepage. F05 low: Responsive behavior relies on viewport breakpoints rather than component containers.
adapt-to-the-form-factor `input-modality-aware`	pass	high	Programmatic keyboard focus matched :focus-visible and computed outline rgb(16,16,16) auto 1px.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	Homepage clearly identifies Walmart, exposes search, departments and direct Shop/Add calls to action.

be-inclusive `zoom-reflow-targets-and-media`	pass	high	No horizontal overflow, scaling is not disabled, and sampled controls remain usable at the narrow viewport.
follow-best-practices `no-console-errors`	issues	high	Lighthouse found 17 browser-console error entries. F11 medium: The page logs many browser errors during load.
follow-best-practices `sound-document-and-assets`	issues	high	Image audit found 8 oversized images, 19 legacy-format images, 3 without srcset and 1 missing alt; all had dimensions. F12 medium: Images are frequently oversized or delivered in legacy formats.
follow-best-practices `browser-platform-hygiene`	issues	high	Lighthouse found 17 browser-console error entries. F13 medium: The cold load emits inspector-visible browser errors.
be-discoverable `title-and-description`	pass	high	Discoverability capture fetched HTTP 200 raw HTML, found 82% rendered-word coverage, no JS shell, and title/H1/meta description in raw HTML. DOM probe found a descriptive title, meta description, canonical URL, viewport and two JSON-LD blocks; robots.txt is valid and lists sitemaps.
be-discoverable `crawlable-and-mobile-friendly`	pass	high	Discoverability capture fetched HTTP 200 raw HTML, found 82% rendered-word coverage, no JS shell, and title/H1/meta description in raw HTML. DOM probe found a descriptive title, meta description, canonical URL, viewport and two JSON-LD blocks; robots.txt is valid and lists sitemaps.

be-private-and-secure `secure-transport-and-headers`	issues	high	HTTPS, CSP, HSTS, frame protections and Permissions-Policy are present, but X-Content-Type-Options and Referrer-Policy are absent. Cookie audit found 16 cookies reported without Secure and several SameSite=None; vtc lasts 400 days. F14 high: Cookie and response-header hardening is incomplete.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	Tracker capture found seven third-party origins and known Google advertising and Criteo endpoints. HAR recorded 422 requests and 3,629,747 transferred bytes, including 266 scripts (2,929,970 bytes) and 390 third-party requests. F15 high: The homepage has a large third-party and tracking footprint.
be-private-and-secure `in-context-permissions-and-modern-auth`	blocked	medium	Attempted clean-CDP navigation was redirected to /blocked and displayed a PerimeterX “Robot or human?” press-and-hold challenge.
be-private-and-secure `defensive-browser-policies`	issues	high	HTTPS, CSP, HSTS, frame protections and Permissions-Policy are present, but X-Content-Type-Options and Referrer-Policy are absent. Cookie audit found 16 cookies reported without Secure and several SameSite=None; vtc lasts 400 days. F16 medium: Defensive policy coverage has material gaps.
be-resilient `progressive-enhancement`	pass	high	Crawler capture retained 82% of homepage content without JavaScript, so the core homepage is server rendered.
be-resilient `resilient-runtime-behaviour`	pass	high	The visible challenge overlay remains within the viewport and provides a close control; core homepage content rendered robustly.
be-resilient `offline-and-installable`	not-applicable	medium	No manifest or controlling service worker was present; offline installability is not applicable to this intrinsically network-dependent retail catalog.
be-resilient `network-and-http-failure-states`	pass	high	Blocked requests show a clear human-verification state rather than a blank shell, with an explicit recovery action.
be-internationalised `lang-dir-and-logical-properties`	issues	high	DOM declares lang=en-US, but rendered CSS contains extensive physical left/right declarations and no document dir. F17 low: Layout CSS is not writing-mode resilient.
be-internationalised `locale-aware-data`	blocked	medium	No representative date/time formatting surface was reachable and source was not provided; the attempted DOM method cannot establish implementation correctness.
be-internationalised `time-zone-correctness`	blocked	medium	No representative date/time formatting surface was reachable and source was not provided; the attempted DOM method cannot establish implementation correctness.
be-trustworthy `no-dark-patterns`	pass	high	The sampled homepage discloses the $1 Walmart+ offer, 30-day duration, $35 minimum and terms link without confirmshaming.

be-trustworthy `trustworthy-input-assistance`	issues	high	The only accessible homepage input is search with autocomplete="off"; search/product/account flows could not be exercised through the bot wall. F18 medium: The primary search input disables browser autocomplete.
be-trustworthy `safe-commercial-and-account-flows`	blocked	medium	Attempted clean-CDP navigation was redirected to /blocked and displayed a PerimeterX “Robot or human?” press-and-hold challenge.
be-sustainable `optimised-assets`	issues	high	Image audit found 8 oversized images, 19 legacy-format images, 3 without srcset and 1 missing alt; all had dimensions. F19 medium: Image delivery wastes bytes and misses modern formats.
be-sustainable `no-wasteful-work`	issues	high	HAR and image evidence show 3.63 MB/422 requests, 2.93 MB script, 19 legacy images and 390 requests classified third-party. F20 high: The homepage performs disproportionate scripting and background requests.
be-sustainable `third-party-and-media-budget`	issues	high	HAR and image evidence show 3.63 MB/422 requests, 2.93 MB script, 19 legacy images and 390 requests classified third-party. F21 high: Third-party requests dominate the network budget.
be-agent-ready `structured-agent-capabilities`	issues	high	DOM probe found two JSON-LD blocks but no WebMCP surface and no on-device inference API usage. F22 low: A major commerce flow exposes no structured agent actions.
be-agent-ready `on-device-inference`	not-applicable	medium	No summarization or local-inference feature was present, and the sampled retail homepage has no clear on-device inference requirement.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	low	Heap summaries were stable after the attempted repeated carousel interaction: 947,685→947,972 nodes (+287) and 57,860,232→57,854,336 bytes (-5,896).
be-memory-efficient `bounded-footprint`	issues	high	Baseline heap contained 947,685 nodes, 63,515 closures and 57.86 MB self size on a single homepage view. F23 medium: The initial homepage JavaScript heap is disproportionately large.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	Heap summaries were stable after the attempted repeated carousel interaction: 947,685→947,972 nodes (+287) and 57,860,232→57,854,336 bytes (-5,896).
