All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	The desktop capture and the prefers-color-scheme: light capture are byte-identical (44,198 bytes), while CSS hard-codes body background #242428 and has no preference rule. F01 medium: The site forces one dark palette instead of following the user’s light/dark preference.
respect-user-preferences `respects-reduced-motion`	pass	high	The preference matched and document.getAnimations() returned no active animations; there is no non-essential motion to suppress.
respect-user-preferences `respects-contrast`	issues	high	Under prefers-contrast: more, the page has no prefers-contrast/forced-colors rules; Lighthouse measured the share count at 2.49:1. F02 medium: High-contrast preferences are not handled and already-low-contrast text remains unchanged.
implement-natural-interactions `view-transitions`	issues	high	The CTA has no href, dispatching its click returned false and changed neither location nor opened window; CSS has no view-transition rules. F03 high: The primary state change is an inert, abrupt dead end rather than a working transition.
implement-natural-interactions `scroll-driven-animations`	not-applicable	high	The page has no scroll-linked animation, parallax, reveal, carousel, or scrollytelling interaction to implement.
implement-natural-interactions `physical-gestures`	not-applicable	high	The static landing page exposes no gesture-driven, swipe, pull, snap, or intrinsic-size interaction.
provide-guided-navigation `scroll-state-aware-chrome`	issues	high	Mobile layout measured 7,737px document height, while the screenshot/DOM show no sticky navigation, progress marker, or scroll-state chrome. F04 medium: The very long page offers no position-aware navigation or progress feedback.
provide-guided-navigation `anchored-positioning`	not-applicable	high	No tooltip, popover, menu, or other anchored overlay exists on this page.
provide-guided-navigation `directs-attention`	issues	high	The prominent “View Full Site” anchor has no href or click handler and the click probe produced no navigation. F05 high: The main call to action looks actionable but provides no navigational focus change or destination.
maximize-content-reduce-noise `no-intrusive-interruptions`	pass	high	No modal, interstitial, consent wall, or obscuring banner appeared on load.
maximize-content-reduce-noise `semantic-dismissible-primitives`	not-applicable	high	The DOM contains no overlays, disclosures, pickers, dialogs, or transient controls requiring a semantic primitive.
maximize-content-reduce-noise `reduced-chrome`	pass	high	The page uses a content-first single column with restrained chrome; the first viewport is not crowded by application framing.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	pass	high	scrollWidth and clientWidth were both 360px, horizontalOverflowPx was 0, and a viewport meta tag is present.
adapt-to-the-form-factor `component-level-responsiveness`	issues	high	CSS inspection found no @container rules; components such as the share block are controlled by max-width media queries only. F06 low: Responsiveness is implemented only with global viewport breakpoints.
adapt-to-the-form-factor `input-modality-aware`	issues	high	The first focusable anchor computed outline:none and box-shadow:none; the probe found visible link boxes only 20px high. F07 high: Keyboard focus is invisible and some links have undersized hit areas.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	The H1 identifies the movie-site proposition and the high-contrast full-width CTA is visually dominant.
support-core-task-success `primary-flow-completion`	issues	high	The “View Full Site” control is an anchor without href or handler; the click probe opened nothing and stayed on the landing page. F08 critical: The only primary journey cannot be completed.
support-core-task-success `clear-system-state-and-recovery`	issues	high	After an attempted click, location and opened-window state were unchanged and no error/status UI appeared. F09 high: The failed CTA gives no state, explanation, retry, or fallback destination.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse measured LCP at 2.8s (good is <=2.5s), although TBT was 0ms and CLS 0.058. F10 medium: Lab LCP misses the good Core Web Vitals threshold.
be-fast-and-stable `visual-stability`	pass	high	The mobile layout observer measured CLS 0.0013 and Lighthouse measured 0.058, both in the good range.
be-fast-and-stable `efficient-main-thread`	pass	high	The trace and layout evidence recorded zero long tasks and 0ms total blocking time.
be-fast-and-stable `efficient-resource-delivery`	issues	high	HAR confirms three parser-inserted VeryHigh-priority stylesheets and synchronous jQuery/Bootstrap scripts; Lighthouse estimates 400ms render-blocking savings and flags cache/font issues. F11 medium: Render-blocking and cache policy choices delay a small static page.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Lighthouse estimates 109KiB unused JS and 35KiB unused CSS; HAR shows 265,915 script bytes, including jQuery 3.3.1, Bootstrap 4.1.3, duplicate ShareThis configuration, and analytics. F12 medium: Most script bytes deliver little value and duplicate/legacy dependencies are loaded.
be-inclusive `names-roles-labels`	issues	high	Lighthouse reports no main landmark and invalid list children; two href-less anchors are exposed as links without a destination. F13 high: The document structure and interactive semantics are invalid despite images having alt text.
be-inclusive `sufficient-contrast`	issues	high	Lighthouse measured #555 text on #121315 at 2.49:1 for the “58.2k Shares” text, below the required 4.5:1. F14 medium: Share-count text fails minimum contrast.
be-inclusive `structure-and-focus`	issues	high	Computed focus on the first anchor was outline:none with no box shadow; Lighthouse found no main landmark and non-li children inside a ul. F15 high: Keyboard focus is invisible and landmark/list structure is malformed.
be-inclusive `legible-text`	pass	high	Body copy reflows cleanly without clipping; heading hierarchy is visually distinct and line lengths are comfortable on mobile.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	The viewport declares maximum-scale=1; Lighthouse fails meta-viewport, and the target probe found visible links only 20px high. F16 high: The viewport disables user zoom and some targets are too short.
follow-best-practices `no-console-errors`	issues	high	Lighthouse captured a ShareThis configuration error and two uncaught TypeErrors from ShareThis count/config scripts. F17 medium: Third-party scripts throw errors during load.
follow-best-practices `sound-document-and-assets`	issues	high	Lighthouse reports no HTML doctype; the images primitive found all six images missing width/height and one oversized SVG. F18 high: The page runs in quirks mode and images lack intrinsic dimensions.
follow-best-practices `browser-platform-hygiene`	issues	high	Lighthouse reports three BFCache blockers caused by cache-control:no-store/cookie modification; it also records exceptions from old third-party integrations. F19 medium: The page prevents BFCache and relies on stale/broken libraries.
be-discoverable `title-and-description`	issues	high	The raw and rendered page both expose title “HDHub4u” and a description, but the title omits the page purpose represented by the H1. F20 low: The title is too generic to distinguish the page in results.
be-discoverable `crawlable-and-mobile-friendly`	issues	high	Lighthouse flags two anchors without href, including “View Full Site”; only a minor body link has a real destination. F21 high: The prominent logo and primary CTA are not crawlable links.
be-discoverable `canonical-and-indexing-signals`	issues	high	The page has no canonical link; /sitemap.xml returns the homepage HTML, while robots.txt advertises indexing and does not provide a valid sitemap URL. F22 medium: Indexing signals are inconsistent and the sitemap endpoint is not a sitemap.
be-discoverable `structured-and-shareable-metadata`	issues	high	The page has no JSON-LD and only og:type; it lacks Open Graph title, description, image, URL, and Twitter card metadata. F23 medium: Share and entity metadata are incomplete.
be-private-and-secure `secure-transport-and-headers`	issues	high	Headers evidence shows no CSP, HSTS, nosniff, clickjacking, referrer, or permissions policy; both analytics cookies lack Secure and use SameSite=None. F24 high: HTTPS is used, but baseline security headers and cookie protections are absent.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	Trackers found 15 third-party origins and Google Analytics; HAR attributes 23/26 requests and 394,881/414,499 bytes to third parties, with 400-day analytics cookies. F25 high: A simple landing page sends most bytes through a large tracking/third-party footprint.
be-private-and-secure `in-context-permissions-and-modern-auth`	not-applicable	high	The page has no authentication flow and does not request geolocation/notification permissions, so modern-auth and prompt timing are not applicable.
be-private-and-secure `defensive-browser-policies`	issues	high	The headers primitive found HSTS, clickjacking protection, Referrer-Policy, Permissions-Policy, and CSP all absent. F26 high: No browser-enforced defensive policies are configured.
be-resilient `progressive-enhancement`	pass	high	Raw HTML returned 200 and contained 100% of rendered content tokens, title, H1 and description; the page is not a JS shell.
be-resilient `resilient-runtime-behaviour`	issues	high	The CTA has no href or handler and clicking it produces no state change, while third-party scripts throw uncaught errors. F27 high: The primary runtime action is fragile and non-semantic.
be-resilient `offline-and-installable`	not-applicable	high	This is a static gateway/content landing page rather than an app; installability and offline app behavior are not proportionate requirements.
be-resilient `network-and-http-failure-states`	issues	high	A request to /web-uplift-definitely-missing-404 returned HTTP 200 and the full homepage, with no 404 explanation or recovery links. F28 medium: Unknown URLs return a misleading successful homepage instead of a recoverable not-found state.
be-internationalised `lang-dir-and-logical-properties`	issues	high	html lang=en is correct, but CSS inspection found no logical properties and 24 rules using physical left/right positioning or spacing. F29 medium: The language is declared, but layout CSS is built from physical directions.
be-internationalised `locale-aware-data`	not-applicable	high	The page renders no dates, numbers requiring locale formatting, prices, currencies, durations, or calendar data.
be-internationalised `time-zone-correctness`	not-applicable	high	The page presents no times, events, recurring schedules, or time-zone-sensitive data.
be-trustworthy `no-dark-patterns`	issues	high	Visible copy claims “Secure and Safe Browsing” and an ad-free experience, while evidence shows 15 third-party origins, analytics tracking, insecure 400-day cookies, absent security headers, and a dead primary CTA. F30 high: Safety claims conflict with observable tracking and security posture.
be-trustworthy `humane-error-handling`	not-applicable	high	There are no forms or user-editable inputs on the audited page.
be-trustworthy `trustworthy-input-assistance`	not-applicable	high	There are no address, payment, sign-in, sign-up, or other input fields requiring autocomplete assistance.
be-trustworthy `safe-commercial-and-account-flows`	not-applicable	high	No checkout, subscription, consent, authentication, or account-management flow is present on this landing page.
be-sustainable `optimised-assets`	pass	high	All six image resources use WebP or SVG and total image transfer is only 13,563 bytes; the one oversized item is a tiny vector icon.
be-sustainable `no-wasteful-work`	issues	high	Third parties account for 394,881 of 414,499 transferred bytes; Lighthouse estimates 109KiB unused JS and 35KiB unused CSS. F31 medium: Most transferred code is avoidable third-party work for a static page.
be-sustainable `third-party-and-media-budget`	issues	high	HAR records 23 third-party requests and 394,881 third-party bytes; GTM alone transfers 154,903 bytes and ShareThis spans multiple origins. F32 high: Third-party scripts and fonts dominate a page whose core content is static HTML.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	The site exposes no transactional or productivity capability for an agent beyond reading content and following one link; WebMCP tooling would not be proportionate.
be-agent-ready `on-device-inference`	not-applicable	high	The static gateway has no inference task where an on-device model or summarizer would improve the core experience.
be-memory-efficient `no-leak-under-repeated-interaction`	not-applicable	high	The page has no functioning representative repeated interaction: its only primary CTA is inert, so fabricating a ten-cycle interaction would not test real use.
be-memory-efficient `bounded-footprint`	pass	high	The rendered page retained 149,737 nodes and 7,849,687 bytes self-size, a modest bounded footprint for the loaded page and third-party widgets.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	No Detached* constructor appears among the leading retained constructors; with no repeatable interaction, the static state shows no direct detached-DOM signal.
