All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	Under emulated prefers-color-scheme: dark, the body remained rgb(237,242,242), the root color-scheme was normal, and the dark screenshot retained light surfaces. F01 medium: Under emulated prefers-color-scheme: dark, the body remained rgb(237,242,242), the root color-scheme was normal, and the dark screenshot retained light surfaces..
respect-user-preferences `respects-reduced-motion`	pass	high	Under prefers-reduced-motion: reduce, getAnimations() returned no active animations on the loaded homepage.
respect-user-preferences `respects-contrast`	pass	high	The forced-colors/high-contrast screenshot retained visible text, controls, dialog boundaries and actions; Lighthouse also passed color contrast.
implement-natural-interactions `view-transitions`	issues	medium	Rendered CSS inspection found zero view-transition declarations across the multi-route marketplace; route changes use full page swaps without continuity. F02 low: Rendered CSS inspection found zero view-transition declarations across the multi-route marketplace.
implement-natural-interactions `scroll-driven-animations`	pass	medium	CSSOM found no animation-timeline/scroll-timeline usage, and recon found no scroll-linked visual effect that required a main-thread or declarative implementation.
implement-natural-interactions `physical-gestures`	pass	medium	The tested marketplace paths used native scrolling and conventional button/link controls; no custom pointer-driven gesture that fights platform behavior was observed.
provide-guided-navigation `scroll-state-aware-chrome`	issues	medium	CSSOM found no scroll-state or scroll-timeline signal; the long listing keeps static chrome and provides no progress/position feedback. F03 low: CSSOM found no scroll-state or scroll-timeline signal.
provide-guided-navigation `anchored-positioning`	not-applicable	high	No tooltip or edge-positioned transient menu was required on the representative public paths; the visible country/consent surfaces are modal dialogs, not anchored popovers.
provide-guided-navigation `directs-attention`	pass	high	Catalog and item paths expose breadcrumbs, clear headings and visible focus cues, preserving orientation from listing to detail.
maximize-content-reduce-noise `no-intrusive-interruptions`	issues	high	A first-visit screenshot shows two simultaneous interruptions before interaction: a centered country modal obscures the page while a full-width consent banner covers the lower viewport; on 360x800 the country modal consumes nearly the whole screen. F04 high: A first-visit screenshot shows two simultaneous interruptions before interaction: a centered country modal obscures the page while a full-width consent banner covers the lower viewport.
maximize-content-reduce-noise `semantic-dismissible-primitives`	issues	high	Overlay inventory found three custom DIV role=dialog surfaces and no native dialog/popover elements; the visible country modal is manually implemented rather than using the platform dialog primitive. F05 medium: Overlay inventory found three custom DIV role=dialog surfaces and no native dialog/popover elements.
maximize-content-reduce-noise `reduced-chrome`	pass	medium	After accounting for first-visit overlays, the homepage and item template devote the main area to products, imagery, price and primary actions with restrained persistent chrome.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	pass	high	At 360x800, homepage and item layout probes both reported scrollWidth=clientWidth=360, horizontalOverflowPx=0, and a viewport meta tag.
adapt-to-the-form-factor `component-level-responsiveness`	issues	medium	CSSOM inspection found zero @container rules despite cards, header controls and commerce panels being reused across listing/detail and narrow/wide contexts. F06 low: CSSOM inspection found zero @container rules despite cards, header controls and commerce panels being reused across listing/detail and narrow/wide contexts..
adapt-to-the-form-factor `input-modality-aware`	pass	medium	Visible keyboard-focused controls had a browser focus outline, navigation controls were generally 36-44px high, and the mobile layouts remained operable.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	The homepage first content clearly asks users to sell and offers “Commencer à vendre”; item pages expose price, “Acheter”, offer and message actions.
support-core-task-success `primary-flow-completion`	pass	medium	The representative browse journey reached catalog, a live item with price and protection details, and the clearly-labelled purchase/signup entry without a dead end; account creation was not completed to avoid side effects.
support-core-task-success `clear-system-state-and-recovery`	pass	high	An invalid route rendered an explicit Page not found state with “Explore Vinted” and “Visit Help Center” recovery actions.
be-fast-and-stable `good-core-web-vitals`	issues	high	Mobile Lighthouse measured LCP 7.5s, FCP 6.1s, TBT 1,180ms and performance 0.33; the first-party trace still recorded LCP 2.26s and 435ms TBT under a separate run. F07 high: Mobile Lighthouse measured LCP 7.5s, FCP 6.1s, TBT 1,180ms and performance 0.33.
be-fast-and-stable `visual-stability`	pass	high	Homepage mobile CLS was 0.060 and item mobile CLS 0.053, both below the 0.1 good threshold.
be-fast-and-stable `efficient-main-thread`	issues	high	Trace recorded six long tasks, a 271ms longest task and 434.76ms total blocking time; Lighthouse measured 1,180ms TBT. F08 high: Trace recorded six long tasks, a 271ms longest task and 434.76ms total blocking time.
be-fast-and-stable `efficient-resource-delivery`	issues	high	HAR recorded 144 requests and 3,169,147 transferred bytes, including 73 scripts (1.30MB) and 29 images (834KB), while loadEventEnd was about 4.88s in the runtime probe. F09 high: HAR recorded 144 requests and 3,169,147 transferred bytes, including 73 scripts (1.30MB) and 29 images (834KB), while loadEventEnd was about 4.88s in the runtime probe..
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Lighthouse estimated 267KiB unused JavaScript and 95KiB unused CSS; individual chunks were 57-87% unused and a primary CSS file was 93% unused. F10 medium: Lighthouse estimated 267KiB unused JavaScript and 95KiB unused CSS.
be-inclusive `names-roles-labels`	pass	high	Lighthouse accessibility scored 0.97 and passed button-name, link-name and form-label audits; product images carried detailed alt text.
be-inclusive `sufficient-contrast`	pass	high	Lighthouse passed its color-contrast audit and the forced-colors capture retained readable controls and copy.
be-inclusive `structure-and-focus`	pass	medium	The page has header/nav/main/footer landmarks, a skip link, sequential heading audit pass, and visible outlines on focused visible links, inputs and category buttons.
be-inclusive `legible-text`	pass	high	Representative desktop and mobile screenshots show readable text sizing, unclipped product details and clear action labels; no horizontal overflow was measured.
be-inclusive `zoom-reflow-targets-and-media`	pass	high	Viewport permits scaling, both 360px probes reflowed without overflow, and no essential audio/video needing captions appeared on audited paths.
follow-best-practices `no-console-errors`	pass	high	Lighthouse reported “No browser errors logged to the console” with an empty details list.
follow-best-practices `sound-document-and-assets`	issues	high	The document has valid doctype/UTF-8 and correct displayed aspect ratios, but all 30 img elements lacked width/height attributes, 25 below-fold images were not lazy, and 22 lacked srcset. F11 medium: The document has valid doctype/UTF-8 and correct displayed aspect ratios, but all 30 img elements lacked width/height attributes, 25 below-fold images were not lazy, and 22 lacked srcset..
follow-best-practices `browser-platform-hygiene`	issues	high	Lighthouse found four BFCache blockers and three deprecated-API warnings from the challenge script, including deprecated Shared Storage and persistent storage usage. F12 medium: Lighthouse found four BFCache blockers and three deprecated-API warnings from the challenge script, including deprecated Shared Storage and persistent storage usage..
be-discoverable `title-and-description`	pass	high	Homepage, catalog/item and signup surfaces have descriptive titles; homepage has a substantive meta description.
be-discoverable `crawlable-and-mobile-friendly`	pass	high	Lighthouse passed crawlable anchors and descriptive link text; the DOM has real href links, index robots meta and a valid viewport tag.
be-discoverable `canonical-and-indexing-signals`	pass	high	The homepage returns 200, declares canonical https://www.vinted.fr/, exposes 27 hreflang alternatives, robots and sitemap are reachable, and robots meta is index.
be-discoverable `structured-and-shareable-metadata`	pass	high	Homepage provides WebPage/Organization JSON-LD and complete Open Graph/Twitter metadata; the audited item provides matching Product/Offer JSON-LD with price, currency, availability and image.
be-private-and-secure `secure-transport-and-headers`	issues	high	The page is HTTPS, but the header primitive found no CSP, HSTS or nosniff header; 12 of 16 first-party cookies lacked Secure, including long-lived identifiers/session-adjacent cookies. F13 high: The page is HTTPS, but the header primitive found no CSP, HSTS or nosniff header.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	The consent UI states 800 partners and purposes including precise geolocation/device identification; network recon contacted 12 non-document origins and multiple metrics/log ingress services on first load. F14 high: The consent UI states 800 partners and purposes including precise geolocation/device identification.
be-private-and-secure `in-context-permissions-and-modern-auth`	issues	medium	No browser permission was granted or prompted on load, but the signup path exposed Google/Apple/Facebook/email methods and no passkey/WebAuthn option or credential registration surface. F15 medium: No browser permission was granted or prompted on load, but the signup path exposed Google/Apple/Facebook/email methods and no passkey/WebAuthn option or credential registration surface..
be-private-and-secure `defensive-browser-policies`	issues	high	Headers lacked clickjacking protection, Referrer-Policy and Permissions-Policy as well as CSP/HSTS. F16 high: Headers lacked clickjacking protection, Referrer-Policy and Permissions-Policy as well as CSP/HSTS..
be-resilient `progressive-enhancement`	pass	medium	Raw server HTML returned 200 with title and meta description, was not a JS shell, and contained 53% of rendered content vocabulary; core marketplace copy/links remained present to a no-JS crawler.
be-resilient `resilient-runtime-behaviour`	pass	medium	Country and privacy dialogs remained contained/scrollable at narrow width, mobile paths had no horizontal clipping, and repeated modal interaction did not increase retained heap.
be-resilient `offline-and-installable`	not-applicable	high	The audited public marketplace has no manifest or controlling service worker and purchasing depends on live inventory, identity and payment; installability/offline transaction support is not a reasonable requirement for this scoped public-web audit.
be-resilient `network-and-http-failure-states`	pass	high	A representative missing route produced an actionable error state rather than a blank shell, with links back to marketplace and help.
be-internationalised `lang-dir-and-logical-properties`	issues	medium	The page correctly declares lang=fr-FR and 27 hreflang variants, but CSSOM found zero logical-property signals and 147 physical left/right declarations, weakening writing-mode resilience. F17 low: The page correctly declares lang=fr-FR and 27 hreflang variants, but CSSOM found zero logical-property signals and 147 physical left/right declarations, weakening writing-mode resilience..
be-internationalised `locale-aware-data`	pass	high	French price rendering uses decimal commas, nonbreaking spaces and EUR symbols consistently, and locale metadata declares fr-FR across representative listing/item paths.
be-internationalised `time-zone-correctness`	not-applicable	high	The public audited paths show relative recency labels and product commerce data, but no scheduled cross-zone event, stored appointment or exact civil time requiring DST/time-zone arithmetic.
be-trustworthy `no-dark-patterns`	pass	medium	The consent banner provides equally visible “Accepter tout” and “Cookies requis uniquement” choices plus management, item prices show both base and buyer-protection-inclusive totals, and purchase commitments are labelled.
be-trustworthy `humane-error-handling`	pass	medium	The tested 404 error uses neutral language and clear recovery actions; Lighthouse passed labels and accessible names. No premature validation was observed on the exposed search/signup entry.
be-trustworthy `trustworthy-input-assistance`	pass	medium	The public signup entry offers established identity providers and an email route; the exposed search fields do not collect address/payment/account data requiring specialized autocomplete tokens.
be-trustworthy `safe-commercial-and-account-flows`	pass	high	The item page clearly displays item price, buyer-protection-inclusive total, shipping starting price, safety policy and distinct Buy/Offer/Message actions before signup.
be-sustainable `optimised-assets`	issues	high	Although 27 of 30 images were modern formats, 25 below-fold images were eager, 22 lacked responsive srcset, one hero was oversized and three assets used legacy formats. F18 medium: Although 27 of 30 images were modern formats, 25 below-fold images were eager, 22 lacked responsive srcset, one hero was oversized and three assets used legacy formats..
be-sustainable `no-wasteful-work`	issues	high	First load transferred 3.17MB over 144 requests with 73 scripts, while Lighthouse identified 267KiB unused JS and the trace recorded 435ms blocking time. F19 medium: First load transferred 3.17MB over 144 requests with 73 scripts, while Lighthouse identified 267KiB unused JS and the trace recorded 435ms blocking time..
be-sustainable `third-party-and-media-budget`	issues	high	Twelve non-document origins participated in load; third-party-style asset, consent, metrics, logging and bot-defense services contributed to a 144-request, 3.17MB first visit. F20 medium: Twelve non-document origins participated in load.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	No declared agent-facing intent or WebMCP surface was found. Although product JSON-LD aids extraction, this emerging capability is not assumed without site intent.
be-agent-ready `on-device-inference`	not-applicable	high	No summarisation or language-model task was present on the representative commerce paths that would justify built-in on-device inference.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	medium	After ten open/close attempts of the locale modal, heap totals were lower than the independent baseline: 822,402 vs 827,084 nodes and 45.29MB vs 45.58MB self size; no retained-growth signal appeared.
be-memory-efficient `bounded-footprint`	pass	medium	The loaded page used about 74.4MB JS heap and 2,713 live DOM elements; heap snapshot self size was about 45.6MB, proportionate to a product-rich marketplace page.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	medium	The repeated-interaction heap summary did not grow in node count or total self size versus baseline; no accumulating detached-node footprint was signalled by the summaries.
