All 58 atomic check outcomes

Principle / checkStatusConfidenceEvidence or reason
respect-user-preferences
respects-color-scheme
issueshighThe dark-emulated screenshot is pixel-identical to the light capture; the preference probe reports color-scheme normal and body background rgb(255,255,255).
F01 medium: Dark preference is ignored
respect-user-preferences
respects-reduced-motion
passhighReduced-motion emulation was active; getAnimations() returned no running page animations, so no non-essential motion persisted in the sampled load state.
respect-user-preferences
respects-contrast
passhighHigh-contrast emulation was active and screenshots/probes retained dark text and clearly outlined controls; Lighthouse contrast audit scored 1.
implement-natural-interactions
view-transitions
passmediumCSS inspection found view-transition rules, and tested navigational surfaces remained coherent rather than showing a broken intermediate state.
implement-natural-interactions
scroll-driven-animations
not-applicablemediumNo parallax, scrollytelling, or scroll-linked reveal was observed on the four representative templates, so there is no scroll-linked motion implementation to judge.
implement-natural-interactions
physical-gestures
not-applicablemediumNo custom swipe, pull-to-reveal, carousel drag, or other gesture-driven primary interaction was present on the exercised news reading paths.
provide-guided-navigation
scroll-state-aware-chrome
passhighScreenshots and DOM show a persistent, compact fixed header and clear current-section state across homepage, listing and article.
provide-guided-navigation
anchored-positioning
not-applicablemediumNo tooltip, anchored popover, or edge-positioned menu requiring anchor positioning was present in the exercised paths; the load-time interruption is a modal and judged separately.
provide-guided-navigation
directs-attention
passhighRepresentative navigation uses descriptive links, active-section colour, a skip link, and a prominent article hero to preserve orientation.
maximize-content-reduce-noise
no-intrusive-interruptions
issueshighDesktop, mobile, homepage, and article screenshots show a centered notification modal covering the lead story before interaction.
F02 high: Notification solicitation obscures core news on every fresh load
maximize-content-reduce-noise
semantic-dismissible-primitives
issueshighThe overlay probe finds a DIV role=button with aria-modal=true; there is no dialog element and no role=dialog.
F03 medium: Modal uses an invalid ad-hoc role instead of dialog
maximize-content-reduce-noise
reduced-chrome
issueshighDesktop screenshots devote roughly the first 150px below navigation to empty reserved space before the lead story, while the notification overlay further obscures content.
F23 low: Large reserved advertising area delays the news visually
adapt-to-the-form-factor
responsive-no-horizontal-scroll
passhighAt 360x800 the layout primitive measured scrollWidth=clientWidth=360 and zero horizontal overflow; viewport meta is present.
adapt-to-the-form-factor
component-level-responsiveness
issueshighThe preference/CSS probe found no @container rules, despite cards and navigation being reused across wide and narrow columns.
F04 low: Components rely on viewport layout rather than container responsiveness
adapt-to-the-form-factor
input-modality-aware
issueshighThe active-focus probe found no outline or box-shadow on most sampled links/buttons, including logo, top navigation, menu, and article links; several top-nav targets are only 14-16px high.
F06 high: Keyboard focus is not visibly exposed on primary controls
support-core-task-success
clear-purpose-and-primary-action
passhighHomepage, category, search, and article screenshots make news reading and article selection immediately understandable with descriptive headings/links.
support-core-task-success
primary-flow-completion
passhighThe representative flow from homepage headline to a complete article loaded successfully without an account wall.
support-core-task-success
clear-system-state-and-recovery
issueshighThe exercised unknown URL says the page could not load but exposes no retry, home, search, or relevant-content links in main.
F07 medium: 404 state is a dead end
be-fast-and-stable
good-core-web-vitals
issueshighTrace recorded FCP 2.78s, LCP 5.58s, four long tasks, longest 452ms, and 808ms total blocking time. Lighthouse on the mandatory privacy-gate journey corroborated 3.9s LCP.
F08 high: Initial rendering is slow and main-thread work is heavy
be-fast-and-stable
visual-stability
issueshighThe image primitive reports all 100 inspected images lack width and height attributes; Lighthouse also flags unsized images, even though the short layout observation saw CLS 0.
F10 medium: Images do not reserve intrinsic space
be-fast-and-stable
efficient-main-thread
issueshighTrace recorded FCP 2.78s, LCP 5.58s, four long tasks, longest 452ms, and 808ms total blocking time. Lighthouse on the mandatory privacy-gate journey corroborated 3.9s LCP.
F08 high: Initial rendering is slow and main-thread work is heavy
be-fast-and-stable
efficient-resource-delivery
issueshighHAR captured 191 requests and 2.57MB transferred, including 1.57MB script and 1.80MB from third-party origins; two classic head scripts are parser-blocking.
F09 high: Network delivery is dominated by scripts and third parties
be-fast-and-stable
trim-unused-and-duplicate-code
issueshighHAR recorded 61 scripts and 1.57MB script transfer; Lighthouse estimates 58KiB unused JavaScript, while advertising and experimentation bundles are among the largest resources.
F11 medium: Large script payload includes avoidable unused and duplicate work
be-inclusive
names-roles-labels
issueshighThe DOM probe found four unnamed controls, including search/settings and carousel arrows; the image audit found three missing alt values in its loaded sample.
F05 high: Several controls and images lack accessible names
be-inclusive
sufficient-contrast
passhighLighthouse color-contrast audit scored 1 and visual screenshots show legible text/control contrast on the sampled surfaces.
be-inclusive
structure-and-focus
issueshighThe category and search templates expose no h1; the focus probe shows most controls without a visible focus style. Lighthouse also found invalid heading order on the consent journey.
F24 medium: Heading and focus structure is inconsistent across templates
be-inclusive
legible-text
passhighArticle screenshot shows readable line length, spacing, and hierarchy without clipping at the tested viewport.
be-inclusive
zoom-reflow-targets-and-media
issueshighThe active-focus probe found no outline or box-shadow on most sampled links/buttons, including logo, top navigation, menu, and article links; several top-nav targets are only 14-16px high.
F06 high: Keyboard focus is not visibly exposed on primary controls
follow-best-practices
no-console-errors
passhighLighthouse errors-in-console audit scored 1 with an empty details list.
follow-best-practices
sound-document-and-assets
issueshighThe image primitive reports all 100 inspected images lack width and height attributes; Lighthouse also flags unsized images, even though the short layout observation saw CLS 0.
F10 medium: Images do not reserve intrinsic space
follow-best-practices
browser-platform-hygiene
issueshighLighthouse reports a cookie issue and three BFCache blockers on the privacy-gate journey; a third-party source map also returns 404.
F12 medium: Browser hygiene is weakened by inspector and BFCache issues
be-discoverable
title-and-description
passhighHomepage and article probes found unique descriptive titles and meta descriptions.
be-discoverable
crawlable-and-mobile-friendly
issueshighDiscoverability reports 0% homepage and 1% article raw-content coverage, no raw title/h1/description, and isJsShell=true. robots.txt disallows GPTBot, ClaudeBot, OAI-SearchBot and other AI agents.
F13 high: Core content is absent from raw HTML and AI crawlers are explicitly blocked
be-discoverable
canonical-and-indexing-signals
passhighHomepage/article expose canonical URLs and index/follow; robots.txt returns 200 and names four working sitemap endpoints.
be-discoverable
structured-and-shareable-metadata
passhighArticle probe found NewsArticle/WebSite JSON-LD plus accurate Open Graph title, description, URL, type and image.
be-private-and-secure
secure-transport-and-headers
issueshighHeaders show CSP allows unsafe-inline and unsafe-eval; 22 of 26 observed first-party-domain cookies lack Secure and many use SameSite=None. HTTPS, HSTS, and nosniff are present.
F14 high: Cookie and CSP posture is too permissive
be-private-and-secure
data-minimisation-and-third-parties
issueshighTracker capture found 52 third-party origins and nine known tracker domains; HAR attributes 157 requests and 1.80MB to third parties, while fresh-load cookies include long-lived advertising/experiment identifiers.
F15 high: Tracking footprint is disproportionate
be-private-and-secure
in-context-permissions-and-modern-auth
passhighNotification permission remained default on load and Lighthouse notification/geolocation-on-start audits scored 1; no browser permission prompt fired before user action.
be-private-and-secure
defensive-browser-policies
issueshighCSP has no frame-ancestors directive, X-Frame-Options and Referrer-Policy are absent, and Permissions-Policy grants only a client-hint rule rather than explicitly restricting sensitive features.
F16 medium: Defensive header policy is incomplete
be-resilient
progressive-enhancement
issueshighRaw fetches contain only 22 text characters and no title, h1, or description while rendered pages contain thousands of characters; both tested templates are classified as JS shells.
F17 high: News content depends on JavaScript
be-resilient
resilient-runtime-behaviour
passhighMenu, fixed header, article, and search states rendered without clipped overlays or broken async shells in the exercised JS-enabled paths.
be-resilient
offline-and-installable
not-applicablemediumNU.nl is a public news publication rather than an installed app journey; a service worker is registered, but offline installability was judged contextual and out of scope.
be-resilient
network-and-http-failure-states
issueshighThe tested 404 route shows only an error message and no links or retry/search action.
F18 medium: Failure recovery lacks useful actions
be-internationalised
lang-dir-and-logical-properties
passmediumThe document declares lang=nl, reading order is LTR as expected, and Dutch content/navigation rendered coherently.
be-internationalised
locale-aware-data
passmediumArticle metadata uses ISO 8601 with +02:00 and the UI renders Dutch date/time labels appropriate to nl-NL.
be-internationalised
time-zone-correctness
passmediumArticle JSON-LD stores an explicit +02:00 offset and visible copy clarifies Nederlandse tijd for the international match.
be-trustworthy
no-dark-patterns
passhighThe sampled public reading flow has descriptive actions and the notification solicitation offers a clearly labelled close control; no forced purchase or disguised ad action was observed.
be-trustworthy
humane-error-handling
passhighNo editable user form was present; the exercised 404 explains the failure plainly, while missing recovery is recorded under core task/resilience.
be-trustworthy
trustworthy-input-assistance
not-applicablemediumThe representative public homepage, listing, article, and search-result URL exposed no editable form fields.
be-trustworthy
safe-commercial-and-account-flows
not-applicablemediumCheckout, subscription management, and authenticated account management were not part of the representative public-news journey and no such flow was exercised.
be-sustainable
optimised-assets
issueshighAll 100 inspected images use legacy JPEG URLs, 24 lack srcset, 25 are over twice displayed width, and 10 below-fold images are not lazy loaded.
F19 high: Image delivery wastes bandwidth
be-sustainable
no-wasteful-work
issueshighHAR records 1.80MB third-party transfer versus 0.77MB first-party, with 157 of 191 requests third-party; tag management, ads, and experimentation are leading costs.
F20 high: Third-party budget outweighs first-party delivery
be-sustainable
third-party-and-media-budget
issueshighHAR records 1.80MB third-party transfer versus 0.77MB first-party, with 157 of 191 requests third-party; tag management, ads, and experimentation are leading costs.
F20 high: Third-party budget outweighs first-party delivery
be-agent-ready
structured-agent-capabilities
not-applicablemediumrobots.txt explicitly blocks major AI agents and the site exposes no intended agent-facing task surface; this emerging capability is therefore judged not applicable by site intent.
be-agent-ready
on-device-inference
not-applicablemediumNo summarisation or language-model user feature is offered, and the site explicitly blocks AI agents; on-device inference is not required for the core news-reading experience.
be-memory-efficient
no-leak-under-repeated-interaction
issueshighAfter ten menu open/close cycles, same-session JS heap rose from 47.6MB to 58.4MB while DOM nodes stayed at 2,857; independent post heap was 53.2MB versus 48.1MB baseline. This is medium-confidence retained-growth evidence, not a proven leak trace.
F21 medium: Repeated menu use retains substantial additional heap
be-memory-efficient
bounded-footprint
issueshighThe baseline heap contains 906,269 nodes, 4.52M edges, 48.1MB self-size, 83,032 closures, and 221,969 objects before extended interaction.
F22 medium: Baseline heap is heavy for a news listing
be-memory-efficient
no-detached-dom-or-unbounded-listeners
issueshighAfter ten menu open/close cycles, same-session JS heap rose from 47.6MB to 58.4MB while DOM nodes stayed at 2,857; independent post heap was 53.2MB versus 48.1MB baseline. This is medium-confidence retained-growth evidence, not a proven leak trace.
