All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | Dark emulation left the document and header white; html computed color-scheme was normal and the CSS probe found no prefers-color-scheme rule. F01 medium: No user-preference dark theme |
respect-user-preferencesrespects-reduced-motion | pass | high | Under prefers-reduced-motion: reduce there were no running animations, all 12 media elements were paused without autoplay, and two stylesheets contained reduced-motion handling. |
respect-user-preferencesrespects-contrast | issues | high | The high-contrast capture remained the ordinary palette and CSS inspection found no prefers-contrast or forced-colors handling. F02 medium: No explicit high-contrast adaptation |
implement-natural-interactionsview-transitions | pass | high | Rendered CSS contained view-transition rules, showing state changes use the platform transition mechanism. |
implement-natural-interactionsscroll-driven-animations | pass | high | Rendered CSS contained animation-timeline/scroll-timeline rules rather than relying only on imperative scrolling. |
implement-natural-interactionsphysical-gestures | pass | high | Rendered CSS uses scroll-snap and the homepage carousel presents native-like previous, next, pause, and position controls. |
provide-guided-navigationscroll-state-aware-chrome | pass | high | Scroll-timeline/scroll-snap styling and explicit carousel position controls provide state-aware navigation feedback. |
provide-guided-navigationanchored-positioning | pass | high | Rendered CSS contains anchor positioning rules, and no sampled menu was visibly detached from its trigger. |
provide-guided-navigationdirects-attention | pass | high | The hero, carousel markers, labelled category navigation, and strong section headings make current context and next destinations visible. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | The consent banner obscures roughly the lower quarter of desktop and almost the entire remaining mobile viewport before interaction. F03 high: Consent UI obscures core content on load |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | The page exposed many custom DIV role=dialog nodes but zero native dialog, popover, or details elements. F04 medium: Overlays rely on custom dialog DIVs |
maximize-content-reduce-noisereduced-chrome | pass | high | After consent rejection, the main surface is content-led with a compact two-row header and no enclosing application frame. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | At a 360px visual viewport, layout reported 407px scroll width and 47px horizontal overflow. F05 medium: Mobile layout overflows horizontally |
adapt-to-the-form-factorcomponent-level-responsiveness | pass | high | CSS inspection found 25 container rules, and header/content composition changes between 1440px and 360px. |
adapt-to-the-form-factorinput-modality-aware | pass | high | Programmatic keyboard focus produced a visible auto outline; Lighthouse target-size passed and primary controls remain available without hover. |
support-core-task-successclear-purpose-and-primary-action | pass | high | Homepage, category, and deals surfaces clearly identify eBay browse/search and expose prominent search and offer actions. |
support-core-task-successprimary-flow-completion | issues | high | A direct search for “iphone 15” and a live item linked from Deals both returned the generic “Something went wrong on our end” error, preventing browse-to-item completion. F06 critical: Search and item journeys fail |
support-core-task-successclear-system-state-and-recovery | pass | high | Both generic failures and the intentional not-found route explain the state and offer a homepage/back or help recovery path. |
be-fast-and-stablegood-core-web-vitals | issues | high | Lighthouse measured LCP 17.0s, FCP 8.3s, TBT 410ms and performance 0.46; trace corroborated LCP 4.83s. F07 high: LCP is outside the good range |
be-fast-and-stablevisual-stability | pass | high | The mobile layout observer and Lighthouse both measured CLS 0 with no recorded layout-shift entries. |
be-fast-and-stableefficient-main-thread | issues | high | Lighthouse reported 9.5s main-thread work and 4.2s JavaScript execution; trace found three long tasks up to 97.6ms. F08 high: Initial load performs excessive main-thread work |
be-fast-and-stableefficient-resource-delivery | issues | high | HAR transferred 3.38MB over 89 requests; Lighthouse found 750ms render-blocking savings and weak caching, while DOM inspection confirmed several parser scripts lacked async/defer. F09 high: Resource delivery delays primary content |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | Lighthouse estimated 563KiB unused JavaScript, 138KiB unused CSS, and 55KiB legacy JavaScript; HAR transferred 1.08MB of script. F10 medium: Large unused and legacy payloads ship on load |
be-inclusivenames-roles-labels | issues | high | Lighthouse failed aria-hidden-focus and label/content-name matching; the image primitive reported 29 images without alt. F11 high: Accessible names and hidden focus state are inconsistent |
be-inclusivesufficient-contrast | pass | high | Lighthouse color-contrast passed with no failing elements. |
be-inclusivestructure-and-focus | issues | high | Keyboard focus was visible, but Lighthouse found no valid main landmark and focusable descendants inside aria-hidden content. F12 high: Main landmark and focus structure are invalid |
be-inclusivelegible-text | pass | high | Desktop and mobile captures show readable type, consistent alignment, and no observed text clipping in the sampled content. |
be-inclusivezoom-reflow-targets-and-media | issues | high | Although Lighthouse target-size and viewport checks passed, the 360px layout still overflowed horizontally by 47px, so reflow is incomplete. F13 medium: Narrow reflow is incomplete |
follow-best-practicesno-console-errors | pass | high | Lighthouse reported no browser errors logged to the console. |
follow-best-practicessound-document-and-assets | issues | high | Document doctype and UTF-8 are valid, but 79 of 80 images lacked explicit dimensions and 35 were oversized. F14 medium: Images omit intrinsic dimensions and are oversized |
follow-best-practicesbrowser-platform-hygiene | issues | high | Lighthouse reported one deprecated API, a BFCache blocker, missing source maps for large first-party JavaScript, and best-practices score 0.81. F15 medium: Deprecated API and BFCache/source-map hygiene gaps remain |
be-discoverabletitle-and-description | pass | high | The homepage has a descriptive German title and detailed meta description. |
be-discoverablecrawlable-and-mobile-friendly | pass | high | Real href links, viewport metadata, readable robots.txt, and Lighthouse SEO 1.00 establish crawlability and mobile indexing signals. |
be-discoverablecanonical-and-indexing-signals | pass | high | Homepage returned 200, canonical points to https://www.ebay.de/, hreflang enumerates localized variants, and no accidental noindex was observed. |
be-discoverablestructured-and-shareable-metadata | pass | high | JSON-LD/Open Graph metadata was present in the rendered profile and Lighthouse SEO scored 1.00. |
be-private-and-securesecure-transport-and-headers | issues | high | HTTPS/HSTS/nosniff/frame protection are present, but CSP is absent and 16 cookies were flagged without Secure by CDP. F16 high: CSP and cookie transport defenses are incomplete |
be-private-and-securedata-minimisation-and-third-parties | issues | high | Before consent, the page set 16 cookies and contacted eight non-main origins; HAR classified 76 requests and 2.70MB outside the main origin. F17 medium: Pre-consent data footprint is broad |
be-private-and-securein-context-permissions-and-modern-auth | pass | medium | No notification/geolocation prompt appeared on load; credential APIs are available and no password-only wall was introduced in sampled public paths. |
be-private-and-securedefensive-browser-policies | issues | high | HSTS and SAMEORIGIN are set, but CSP, Referrer-Policy, and Permissions-Policy are absent. F18 medium: Referrer and permissions policies are absent |
be-resilientprogressive-enhancement | pass | high | Raw HTML returned 200 with 84% rendered-word coverage and retained title, h1, and description; it is not a JS shell. |
be-resilientresilient-runtime-behaviour | pass | high | Sampled category/deals overlays remained within viewport bounds, and explicit error states replaced broken or blank shells. |
be-resilientoffline-and-installable | not-applicable | high | eBay is an intrinsically network-dependent commerce marketplace; installability and a general offline transaction flow are not appropriate to this representative public journey. |
be-resilientnetwork-and-http-failure-states | pass | high | Search/item failures and a 404 each render a clear message and recovery link rather than an infinite spinner or blank shell. |
be-internationalisedlang-dir-and-logical-properties | pass | high | html lang is de-DE, hreflang variants are extensive, and rendered CSS uses logical inline properties. |
be-internationalisedlocale-aware-data | pass | high | German copy and locale-appropriate EUR prices such as “EUR 189,99” are rendered consistently. |
be-internationalisedtime-zone-correctness | pass | medium | The event time is explicitly presented in localized German date/time form, providing an unambiguous local user-facing value. |
be-trustworthyno-dark-patterns | issues | high | The consent wall blocks content and, on mobile, its reject/customize actions are below the first viewport, creating avoidable consent friction. F24 high: Consent choice is obstructive on mobile |
be-trustworthyhumane-error-handling | pass | high | Failure screens use neutral language, explain that the problem is on eBay’s side, retain a reference ID, and offer recovery without blaming the user. |
be-trustworthytrustworthy-input-assistance | pass | high | Search input and category select have explicit accessible labels, appropriate types, and predictable actions. |
be-trustworthysafe-commercial-and-account-flows | issues | high | A live offer linked from Deals cannot reach its item page and instead returns a generic server error, breaking a commercial flow before pricing/commitment can be completed. F25 high: Deal-to-item commercial flow is unavailable |
be-sustainableoptimised-assets | issues | high | 35 images were oversized, 52 lacked srcset, and 20 used legacy formats; images transferred about 2.0MB. F21 medium: Image delivery wastes bytes |
be-sustainableno-wasteful-work | issues | high | The page shipped 563KiB estimated unused JS, 138KiB unused CSS, and 89 requests on initial load. F22 medium: Initial page ships avoidable work |
be-sustainablethird-party-and-media-budget | issues | high | Non-main-origin delivery accounted for 76 requests and 2.70MB; initial total transfer was 3.38MB despite no user-started media. F23 medium: Third-party/media budget is disproportionate |
be-agent-readystructured-agent-capabilities | issues | high | Content is crawler-visible, but no WebMCP, agentic-form, or agentic JavaScript tool registration was exposed for this commerce surface. F19 low: Commerce capabilities are not exposed structurally to agents |
be-agent-readyon-device-inference | not-applicable | high | No bounded on-device inference task was present in the sampled browse, search, deal, or product journey; absence is not a defect for this emerging contextual check. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | After ten carousel-next clicks, snapshot totals were lower (759,595 nodes; 44.6MB) than baseline (813,980 nodes; 63.5MB), with no retained-growth signal. |
be-memory-efficientbounded-footprint | issues | high | Baseline heap contained 813,980 nodes, 3.29M edges, and 63.5MB self size, a high initial footprint for a marketplace landing page. F20 medium: Initial memory footprint is high |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | medium | Ten repeated carousel actions did not increase aggregate nodes, edges, or heap self size; no accumulating detached/listener signal was observed at summary level. |
