All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | Homepage light and dark screenshots are byte-identical (41,016-byte source PNGs); computed color-scheme is normal and CSS has no prefers-color-scheme rule. F01 medium: Dark preference is ignored on the homepage |
respect-user-preferencesrespects-reduced-motion | pass | high | Reduced-motion emulation matched and document.getAnimations() returned an empty list; no non-essential motion remained. |
respect-user-preferencesrespects-contrast | pass | high | The prefers-contrast screenshot retained visible text and native controls; Lighthouse accessibility scored 1.00. |
implement-natural-interactionsview-transitions | issues | high | CSS probe found no view-transition rules and sampled route changes render as full abrupt navigations. F02 low: Route and state changes have no View Transition treatment |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No scroll-linked decorative or scrollytelling effect was present on the representative paths. |
implement-natural-interactionsphysical-gestures | pass | medium | Representative listing/feed paths retained native document scrolling and exposed no custom pointer-driven gesture layer. |
provide-guided-navigationscroll-state-aware-chrome | issues | high | The long homepage/feed has 24,842 px content height, while CSS inspection found no scroll-state query or progress treatment. F03 low: Long feeds provide no scroll-state-aware navigation cue |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip, popover, or edge-positioned menu was exposed in the sampled rendered states. |
provide-guided-navigationdirects-attention | pass | high | Screenshots and DOM show skip links, selected search tabs, descriptive links, headings, and clear “Up next” direction. |
maximize-content-reduce-noiseno-intrusive-interruptions | pass | high | Initial screenshots across five templates show no interstitial, consent wall, or content-obscuring overlay. |
maximize-content-reduce-noisesemantic-dismissible-primitives | pass | high | No custom modal overlay was present; sampled search controls are native buttons/inputs and navigation uses anchors. |
maximize-content-reduce-noisereduced-chrome | pass | high | The watch screenshot devotes nearly all space below the compact header to the player/content region. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | Mobile layout reported scrollWidth 1,138 vs clientWidth 360, horizontalOverflowPx 778; screenshot shows desktop-width content. F04 critical: The homepage overflows by 778 px at a 360 px viewport |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | high | CSS probe found no @container/container-type despite repeated cards reused across homepage, category, channel, and search grids. F05 medium: Repeated cards do not adapt at component scope |
adapt-to-the-form-factorinput-modality-aware | issues | high | Probe enumerated many 17–21 px-high links/buttons and 13 px search-filter inputs; multiple interactive targets are below 24 px. F06 high: Many controls and links are below minimum target size |
support-core-task-successclear-purpose-and-primary-action | pass | high | Homepage H1, feed labels, search control, video titles, and category/channel headings communicate each page purpose. |
support-core-task-successprimary-flow-completion | issues | high | Watch screenshot is a blank black player area; /search/news/videos visibly returns panda results rather than news. F07 critical: Core watch and search journeys do not complete reliably |
support-core-task-successclear-system-state-and-recovery | issues | high | Blank watch player and mismatched search results show no explanatory error, retry, or actionable recovery control. F08 high: The blank player and failed search provide no recovery state |
be-fast-and-stablegood-core-web-vitals | issues | high | Lighthouse performance was 0.54 with LCP 20.5 s, FCP 8.0 s and TTI 20.6 s. F09 critical: Lighthouse measured a 20.5 s LCP |
be-fast-and-stablevisual-stability | pass | high | Layout observer reported CLS 0 with no recorded shifts; Lighthouse also measured CLS 0. |
be-fast-and-stableefficient-main-thread | pass | high | The trace recorded zero long tasks and zero TBT; Lighthouse’s separate throttled run recorded 210 ms TBT. |
be-fast-and-stableefficient-resource-delivery | issues | high | HAR records the parser-blocking stylesheet as net::ERR_BLOCKED_BY_ORB, a 404 image, and a failed manifest. F10 critical: The sole stylesheet is blocked by ORB and supporting assets fail |
be-fast-and-stabletrim-unused-and-duplicate-code | pass | medium | The observed HAR shipped no JavaScript payload on the SEO-rendered homepage and no duplicate script transfer was observed. |
be-inclusivenames-roles-labels | pass | high | Lighthouse accessibility scored 1.00; buttons have accessible text and image links have adjacent descriptive link names. |
be-inclusivesufficient-contrast | pass | high | Lighthouse accessibility scored 1.00 and screenshots retain readable high-contrast foreground/background pairs. |
be-inclusivestructure-and-focus | pass | high | DOM probes show HEADER and MAIN landmarks, one page-level heading on key templates, skip links, and Lighthouse accessibility 1.00. |
be-inclusivelegible-text | issues | high | Homepage screenshot displays browser-default serif text, bullets, and unstyled controls because the stylesheet is blocked. F11 high: Blocked CSS leaves the homepage as cramped browser-default text |
be-inclusivezoom-reflow-targets-and-media | issues | high | At 360×800 the page overflows 778 px; probe also found many 13–21 px-high controls. F12 high: Mobile reflow fails and targets are undersized |
follow-best-practicesno-console-errors | issues | high | Lighthouse audit errors-in-console scored 0. F13 medium: Lighthouse observed browser console errors |
follow-best-practicessound-document-and-assets | issues | high | HAR records blocked CSS and a 404; images probe found all 92 images lack width/height attributes. F14 high: Assets are unsound: blocked CSS, a 404 image, and 92 images without dimensions |
follow-best-practicesbrowser-platform-hygiene | issues | high | Lighthouse valid-source-maps scored 0 for large first-party JavaScript. F15 low: Large first-party JavaScript lacks valid source maps |
be-discoverabletitle-and-description | pass | high | All five probes returned descriptive titles and descriptions, including content-specific video/channel metadata. |
be-discoverablecrawlable-and-mobile-friendly | pass | high | The viewport meta exists, representative links use real href values, and robots.txt allows the audited public paths. |
be-discoverablecanonical-and-indexing-signals | issues | high | Category and search probes returned no rel=canonical; Lighthouse also reports invalid hreflang/canonical signals. F16 medium: Category and search templates omit canonical signals |
be-discoverablestructured-and-shareable-metadata | pass | high | The video detail includes JSON-LD plus complete Open Graph video fields; homepage/channel include Open Graph previews. |
be-private-and-securesecure-transport-and-headers | issues | high | Headers probe confirms HTTPS and HSTS, but CSP and X-Content-Type-Options are missing. F17 high: The document lacks CSP and nosniff despite HTTPS/HSTS |
be-private-and-securedata-minimisation-and-third-parties | pass | high | Tracker probe found no known tracker domains and cookies probe found zero cookies; third-party origins were Dailymotion CDN hosts. |
be-private-and-securein-context-permissions-and-modern-auth | issues | high | Attempting the visible Connect action left the broken homepage unchanged; no in-context authentication UI or modern auth option became available. F18 medium: The authentication entry point does not activate in the observed homepage |
be-private-and-securedefensive-browser-policies | issues | high | Headers probe found no X-Frame-Options/frame-ancestors, Referrer-Policy, or Permissions-Policy. F19 high: Clickjacking, referrer and permissions defenses are absent |
be-resilientprogressive-enhancement | issues | high | Discoverability primitive measured 0% raw/rendered word coverage, raw text 11 characters, no raw title/H1/description, and isJsShell=true. F20 high: Raw HTML exposes none of the rendered content |
be-resilientresilient-runtime-behaviour | issues | high | ORB blocks the only parser-inserted stylesheet, leaving the homepage unstyled while the watch surface presents a blank player. F21 critical: A blocked critical stylesheet collapses the homepage runtime presentation |
be-resilientoffline-and-installable | issues | high | PWA probe found zero service-worker registrations and the linked manifest failed to fetch. F22 medium: The manifest fetch fails and no service worker is registered |
be-resilientnetwork-and-http-failure-states | issues | high | Observed stylesheet/manifest/player failures result in an unstyled page or blank player without retry or offline/error messaging. F23 high: Network/resource failure produces blank or unstyled surfaces without recovery |
be-internationalisedlang-dir-and-logical-properties | issues | high | html lang=en-US and dir=ltr are correct, but sampled CSS contains no logical-property signal for bidi/writing-mode adaptation. F24 low: Locale attributes exist but sampled CSS uses no logical properties |
be-internationalisedlocale-aware-data | pass | medium | The selected en-US document renders relative-duration and content labels consistently with its declared locale; no malformed numeric/currency formatting was observed. |
be-internationalisedtime-zone-correctness | not-applicable | high | The sampled public pages do not provide a user-managed event or scheduling flow requiring time-zone arithmetic. |
be-trustworthyno-dark-patterns | pass | high | Five initial-state screenshots show no consent nag, confirmshaming, disguised ad, forced continuity, or preselected upsell. |
be-trustworthyhumane-error-handling | not-applicable | high | No authored data-entry form was exposed on the public representative paths. |
be-trustworthytrustworthy-input-assistance | not-applicable | high | No address, payment, sign-in, or sign-up form fields were exposed in the sampled public DOM. |
be-trustworthysafe-commercial-and-account-flows | not-applicable | high | No checkout, subscription, or account-management flow was entered; credentials and purchases were intentionally out of scope. |
be-sustainableoptimised-assets | issues | high | Images probe: 92/92 missing dimensions, 48 missing srcset, 2 legacy-format, and zero modern-format images. F25 high: Images omit dimensions, responsive sources, and modern formats |
be-sustainableno-wasteful-work | issues | high | Images probe reports 91 below-fold images without loading=lazy. F26 high: Ninety-one below-fold images load eagerly |
be-sustainablethird-party-and-media-budget | issues | high | HAR loads 74 requests/475,527 bytes; 71 requests and 438,204 bytes are on Dailymotion CDN subdomains, including 69 eager images. F27 medium: The homepage loads 69 images and 438 KB from CDN subdomains up front |
be-agent-readystructured-agent-capabilities | issues | high | DOM/source probes found no WebMCP or agent-tool registration even though search and content retrieval are core capabilities. F28 low: Search/content capabilities are not exposed in a structured agent interface |
be-agent-readyon-device-inference | not-applicable | high | No user-facing summarisation or generative task was offered where on-device inference is required. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | After ten full-feed scroll cycles, retained heap grew only 73,652 bytes (2.9%) and 1,426 nodes, consistent with bounded loading rather than runaway growth. |
be-memory-efficientbounded-footprint | pass | high | Baseline heap summary reports 45,472 nodes and 2.54 MB self size, proportionate to the server-rendered feed state. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | Baseline/post heap summaries show no Detached* constructor among top retained constructors and only small bounded growth after ten cycles. |
