All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | pass | high | The same homepage switches from a white surface/light controls to a black surface/dark controls under prefers-color-scheme; root computed color-scheme is dark in the dark condition. |
respect-user-preferencesrespects-reduced-motion | pass | high | The reduced-motion capture remained static and document.getAnimations() returned no active animations on the four representative pages. |
respect-user-preferencesrespects-contrast | issues | high | The forced-colors screenshot removes the visible H1 while surrounding navigation and cards remain visible. F01 high: Forced-colors mode hides the primary page heading. |
implement-natural-interactionsview-transitions | issues | medium | The recorded listing-to-detail navigation is an abrupt full-document replacement; CSS inspection found no authored view-transition rules. F02 low: Primary navigation swaps documents abruptly. |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No parallax, scroll reveal, scrollytelling, or other scroll-linked motion exists on the audited templates. |
implement-natural-interactionsphysical-gestures | pass | medium | The promoted-listing rail uses native scrollable content with explicit previous/next buttons and no observed custom pointermove gesture layer. |
provide-guided-navigationscroll-state-aware-chrome | issues | medium | The 8,354px listing has static page chrome and no scroll-state query, progress indicator, or position-responsive navigation. F03 low: The long listing offers no position-aware navigation aid. |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip or transient edge-positioned overlay is part of the audited browse-to-detail journey. |
provide-guided-navigationdirects-attention | pass | high | Breadcrumbs, selected filter tabs, descriptive card links, and the detail-page H1 preserve orientation across the browse journey. |
maximize-content-reduce-noiseno-intrusive-interruptions | pass | high | Homepage, listing, detail, and initial sign-in loads show primary content without a marketing modal, consent wall, or obscuring interstitial. |
maximize-content-reduce-noisesemantic-dismissible-primitives | pass | medium | The audited browse flow uses native buttons, links, form controls, and a disclosure button; no custom modal or transient overlay was encountered. |
maximize-content-reduce-noisereduced-chrome | pass | high | The primary viewport is dominated by listings, filters, vehicle imagery, price, and specifications; site chrome is one compact header. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | At a 360px viewport with desktop UA, Chrome lays the page out at 1,024 CSS px and scales it to 0.3516, making text and controls extremely small instead of reflowing. F04 high: Narrow desktop-UA viewports receive a scaled desktop layout rather than responsive reflow. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | high | Across reusable listing cards, filters, and detail panels, CSS inspection found no @container or container-type usage; adaptation depends on whole-page/device treatment. F05 low: Reusable cards and filters have no component-level responsive rules. |
adapt-to-the-form-factorinput-modality-aware | issues | high | Lighthouse passed target size, but the focus probe found 30 sampled interactive elements with neither an outline nor box-shadow in their focused state. F06 high: Keyboard focus is not reliably visible. |
support-core-task-successclear-purpose-and-primary-action | pass | high | The homepage says “Дром Авто - Продажа автомобилей”, immediately exposes vehicle filters, and gives clear listing and “Подать объявление” actions. |
support-core-task-successprimary-flow-completion | pass | high | A user can browse location-filtered listings, open a specific vehicle, and reach price, specifications, VIN information, seller content, and related inventory without a dead end. |
support-core-task-successclear-system-state-and-recovery | pass | high | The 404 state names the problem, provides a prominent homepage recovery link and sitemap link, and retains global navigation. |
be-fast-and-stablegood-core-web-vitals | issues | high | Lighthouse measured LCP 6,757ms (performance 0.68), outside the good range; CLS was 0 and TBT 102ms. The unthrottled trace measured LCP 1,269ms. F07 high: Mobile lab LCP is well outside the good range. |
be-fast-and-stablevisual-stability | pass | high | Layout observer and Lighthouse both measured CLS 0 on the homepage; no visible first-load jump appeared in captures. |
be-fast-and-stableefficient-main-thread | pass | high | The trace reported 2 long tasks, longest 127.3ms, and 81.75ms total blocking time; Lighthouse TBT was 102ms, a bounded rather than dominant main-thread cost. |
be-fast-and-stableefficient-resource-delivery | pass | medium | The load transferred 944KB with no uncompressed text over 2KB, no redirect chain, and an unthrottled 1.27s LCP; five parser stylesheets are the principal blocking resources. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | Lighthouse identified 103KB of unused JavaScript, including 99% unused in one 58KB ui bundle; HAR recorded 46 script requests totaling 564KB. F08 medium: The initial page ships avoidable JavaScript. |
be-inclusivenames-roles-labels | issues | high | Lighthouse found a visible-label/accessibility-name mismatch; the DOM probe found many search controls without explicit labels, and the image audit counted 33 images without alt attributes. F09 medium: Some controls and images lack robust accessible names. |
be-inclusivesufficient-contrast | issues | high | Lighthouse found listing/status text ratios as low as 1.6:1 and repeated 2.17–3.4:1 failures, below WCAG minimums. F10 high: Listing status and secondary text fail minimum contrast. |
be-inclusivestructure-and-focus | issues | high | The document has no main landmark, skips from H1 to H3, and 30 sampled focused controls exposed neither outline nor box-shadow. F06 high: Keyboard focus is not reliably visible. F11 medium: The page lacks a main landmark and has a skipped heading level. |
be-inclusivelegible-text | issues | high | At 360px with desktop UA the 1,024px layout is scaled to 35%, making navigation, filters, and listing metadata too small for comfortable reading. F04 high: Narrow desktop-UA viewports receive a scaled desktop layout rather than responsive reflow. |
be-inclusivezoom-reflow-targets-and-media | issues | high | Touch targets passed Lighthouse, but the narrow desktop-UA viewport does not reflow: it scales a 1,024px page down to 360px, undermining zoom/reflow usability. F04 high: Narrow desktop-UA viewports receive a scaled desktop layout rather than responsive reflow. |
follow-best-practicesno-console-errors | pass | high | Lighthouse errors-in-console audit passed with no items. |
follow-best-practicessound-document-and-assets | issues | high | Doctype and charset are valid and CLS is zero, but 51 of 74 images omit intrinsic dimensions and 57 use legacy formats. F12 medium: Image delivery misses responsive and modern-format opportunities. |
follow-best-practicesbrowser-platform-hygiene | pass | medium | Lighthouse reported no deprecated APIs, no BFCache failure, no console errors, and no notification/geolocation prompt on load; its generic inspector-issues audit was the only failed platform diagnostic. |
be-discoverabletitle-and-description | pass | high | Homepage, listing, and detail pages expose descriptive, route-specific titles and the homepage has a specific meta description. |
be-discoverablecrawlable-and-mobile-friendly | pass | high | Links use real href values, viewport metadata exists, robots allows public listing/detail routes, and Lighthouse SEO scored 1.0. |
be-discoverablecanonical-and-indexing-signals | pass | high | Public pages return 200, the homepage canonical is https://auto.drom.ru/, no accidental noindex was observed, and robots.txt declares generated sitemap indexes. |
be-discoverablestructured-and-shareable-metadata | pass | high | The homepage includes Open Graph title/description/image/url/type, Twitter card metadata, and 23 JSON-LD blocks aligned with the marketplace content. |
be-private-and-securesecure-transport-and-headers | issues | high | HTTPS is used and no sensitive client secret was found, but CSP, HSTS, nosniff, frame protection, Referrer-Policy, and Permissions-Policy are all absent; all 8 observed cookies lack Secure and report SameSite=None. F13 high: Baseline browser security defenses and cookie flags are absent. |
be-private-and-securedata-minimisation-and-third-parties | issues | medium | The page contacts 7 non-origin hosts and emits pageview, visibility-change, viewport, theme, and component-view telemetry automatically; no known third-party tracker signature was detected. F14 medium: The initial view emits granular telemetry before meaningful interaction. |
be-private-and-securein-context-permissions-and-modern-auth | issues | medium | The initial sign-in page offers password and Telegram login only; no passkey/WebAuthn affordance was visible. No browser permission prompt fired on page load. F15 medium: The visible sign-in surface offers no phishing-resistant passkey option. |
be-private-and-securedefensive-browser-policies | issues | high | No HSTS, clickjacking defense, CSP/frame-ancestors, Referrer-Policy, or Permissions-Policy is sent. F13 high: Baseline browser security defenses and cookie flags are absent. |
be-resilientprogressive-enhancement | pass | high | The site is server-rendered rather than a JS shell; browser and crawler views both retain navigation, H1, vehicle cards, prices, and core browse links, with 55–65% rendered-word coverage. |
be-resilientresilient-runtime-behaviour | pass | medium | Server-rendered navigation and native links remain stable across home, listing, detail, and 404 states; no cut-off menu or broken asynchronous shell appeared in the representative journey. |
be-resilientoffline-and-installable | not-applicable | high | This inventory marketplace depends on live vehicle availability and seller data; installability/offline transaction support is not a reasonable requirement for the audited public browse surface. |
be-resilientnetwork-and-http-failure-states | pass | high | The custom 404 clearly explains the missing page and offers direct homepage and sitemap recovery links instead of a blank shell. |
be-internationalisedlang-dir-and-logical-properties | issues | high | The correct lang="ru" is present, but dir is unset and CSS inspection counted 102 physical left/right properties versus zero logical inline/block properties on the listing template. F16 low: Layout CSS is entirely physical-direction based. |
be-internationalisedlocale-aware-data | not-applicable | high | The audited Russian-only surfaces show vehicle model years and ruble prices but no locale-switching, calendar, duration, or user-entered locale-sensitive data flow to test. |
be-internationalisedtime-zone-correctness | not-applicable | high | No events, appointments, recurring intervals, deadlines, or time-zone-sensitive timestamps occur in the audited marketplace journey. |
be-trustworthyno-dark-patterns | pass | medium | Pricing, vehicle condition, seller content, and sign-in choices are presented directly; no confirmshaming, disguised advertising control, preselected continuity, or consent nag was observed. |
be-trustworthyhumane-error-handling | pass | medium | The initial sign-in screen uses visible labels and provides “restore access”; the 404 explains the failure and gives recovery links. No blaming or premature inline error was observed. |
be-trustworthytrustworthy-input-assistance | pass | medium | Search inputs expose task-specific visible prompts, and the sign-in form visibly identifies phone/login and password with an access-recovery route; no paste prevention was observed by Lighthouse. |
be-trustworthysafe-commercial-and-account-flows | pass | medium | Vehicle price and finance terms are prominent on the detail page, and sign-in presents password and Telegram methods plus terms/privacy links without a preselected paid commitment. |
be-sustainableoptimised-assets | issues | high | Of 74 images, 57 use legacy formats, 19 are oversized, 51 lack intrinsic dimensions, and only one uses srcset. F12 medium: Image delivery misses responsive and modern-format opportunities. |
be-sustainableno-wasteful-work | issues | medium | The page automatically sends multiple component-view, visibility, theme, viewport, and page-interaction telemetry requests; 46 script requests are loaded for the initial marketplace view. F14 medium: The initial view emits granular telemetry before meaningful interaction. |
be-sustainablethird-party-and-media-budget | pass | medium | The initial load is under 1MB transferred, has no video/audio or autoplay media, and most non-origin bytes are Drom-owned static assets rather than embedded media platforms. |
be-agent-readystructured-agent-capabilities | not-applicable | high | No WebMCP or agent-tool surface is declared, and this emerging capability was not stated as an intent for the public classifieds site; absence is treated as an opportunity, not a defect. |
be-agent-readyon-device-inference | not-applicable | high | The audited browse/search experience has no summarisation or generative task where built-in on-device inference is necessary. |
be-memory-efficientno-leak-under-repeated-interaction | pass | medium | Heap self size rose 22.25MB to 22.68MB (1.9%) and DOM nodes rose 2,122 to 2,139; this bounded delta does not show unbounded retained growth in the sampled interaction. |
be-memory-efficientbounded-footprint | pass | medium | The homepage retained 22.25MB self size across 363,468 heap nodes and used about 12.8MB JS heap before interaction, proportionate to a media-rich listing page. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | medium | Neither heap summary reports a Detached* constructor among retained populations, and the DOM count changed by only 17 nodes after ten repetitions; no growing detached-node signal was observed. |
