All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | Under emulated prefers-color-scheme: dark, the body remains rgb(255,255,255), computed color-scheme is normal, the screenshot is unchanged, and CSS inspection finds no colour-scheme implementation. F01 medium: The site ignores the user’s dark colour-scheme preference. |
respect-user-preferencesrespects-reduced-motion | pass | high | evaluate probe under reduced motion found zero active animations and CSS includes a reduced-motion media treatment. |
respect-user-preferencesrespects-contrast | pass | medium | Lighthouse contrast audit passed and the high-contrast screenshot retained visible text and controls. |
implement-natural-interactionsview-transitions | issues | medium | CSS inspection across the rendered homepage found no view-transition rules or names; navigation remains a full-document abrupt swap. F02 low: Route changes do not use View Transitions. |
implement-natural-interactionsscroll-driven-animations | pass | medium | CSS probe found no scroll-driven effect and observed scrolling remained native with no long-task scroll animation. |
implement-natural-interactionsphysical-gestures | pass | medium | Mobile topic navigation uses native horizontal scrolling and the page did not expose custom pointer-driven gesture handlers in tested flows. |
provide-guided-navigationscroll-state-aware-chrome | issues | medium | The 31,227px-tall mobile homepage has static chrome; CSS inspection found no scroll timeline or scroll-state implementation and no reading/progress cue. F03 low: The page chrome does not communicate scroll state. |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip/popover/menu positioning defect was exposed in the representative flows, so anchor positioning is not required for the tested surfaces. |
provide-guided-navigationdirects-attention | pass | high | Selected topic chips, headings, skip link, and descriptive navigation labels preserve orientation across tested templates. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | Mobile screenshots show “Activez les notifications” fixed over the bottom of search and 404 content before a user asks for notifications. F04 medium: A notification activation prompt intrudes on search and error journeys. |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | DOM/CSS probe found 11 elements with role=dialog or aria-modal, but zero dialog, popover, or details elements. F05 medium: Overlays are implemented as custom dialog-like structures rather than native primitives. |
maximize-content-reduce-noisereduced-chrome | pass | high | Mobile screenshots prioritize headline imagery and readable content with compact persistent header chrome. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | The layout primitive measured scrollWidth 403px against clientWidth 360px on /monde/, a 43px overflow. F06 medium: The section template overflows horizontally on a 360px viewport. |
adapt-to-the-form-factorcomponent-level-responsiveness | pass | high | Rendered CSS contains @container rules and homepage/article components reflow between desktop and 360px views. |
adapt-to-the-form-factorinput-modality-aware | issues | high | The focus probe found visible elements whose computed outline is none and box-shadow none, including menu/list anchors and buttons; axe also reports structural accessibility failures. F07 high: Some keyboard-focusable controls have no visible focus indicator. |
support-core-task-successclear-purpose-and-primary-action | pass | high | First viewports clearly identify current news, section purpose, article headline, and search action. |
support-core-task-successprimary-flow-completion | pass | high | The labelled search form completed to 100 matching results, and headline links expose real href destinations. |
support-core-task-successclear-system-state-and-recovery | pass | high | A true HTTP 404 presents a clear explanation, search field, homepage/live/TV/radio recovery actions. |
be-fast-and-stablegood-core-web-vitals | issues | high | Lighthouse measured LCP at 4.0s (score 0.50) and FCP at 2.3s; the first-party trace was faster but still confirms load work before content settles. F08 high: Mobile Largest Contentful Paint misses the good Core Web Vitals range. |
be-fast-and-stablevisual-stability | pass | high | Layout observers measured CLS 0 on home and article; Lighthouse CLS was 0.004. |
be-fast-and-stableefficient-main-thread | issues | high | The DevTools trace recorded a 465.22ms task and 421.71ms total blocking time across two long tasks. F09 medium: A long main-thread task blocks responsiveness during load. |
be-fast-and-stableefficient-resource-delivery | issues | high | HAR captured 138 requests: 37 stylesheets and 61 scripts. Scripts transferred 853,978 bytes and the summary identifies many parser-inserted stylesheet candidates. F10 medium: The critical delivery path is fragmented across many CSS and script requests. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | Lighthouse estimates 55KiB unused JavaScript and 16KiB unused CSS on the mobile load. F11 low: The homepage ships avoidable unused CSS and JavaScript. |
be-inclusivenames-roles-labels | issues | high | axe found critical aria-allowed-attr and aria-valid-attr-value violations, 10 malformed lists, 40 orphan list items, a duplicate landmark name, and content outside landmarks; Lighthouse accessibility score is 0.80. F12 high: Invalid ARIA and broken list semantics weaken assistive-technology output. |
be-inclusivesufficient-contrast | pass | high | Lighthouse color-contrast audit passed; screenshots show strong body/control contrast. |
be-inclusivestructure-and-focus | issues | high | The focus probe found visible elements whose computed outline is none and box-shadow none, including menu/list anchors and buttons; axe also reports structural accessibility failures. axe found critical aria-allowed-attr and aria-valid-attr-value violations, 10 malformed lists, 40 orphan list items, a duplicate landmark name, and content outside landmarks; Lighthouse accessibility score is 0.80. F07 high: Some keyboard-focusable controls have no visible focus indicator. F12 high: Invalid ARIA and broken list semantics weaken assistive-technology output. |
be-inclusivelegible-text | pass | high | Article and listing screenshots show readable sizing, spacing, line length, and unclipped wrapping at 360px. |
be-inclusivezoom-reflow-targets-and-media | issues | high | The layout primitive measured scrollWidth 403px against clientWidth 360px on /monde/, a 43px overflow. F06 medium: The section template overflows horizontally on a 360px viewport. |
follow-best-practicesno-console-errors | pass | high | Lighthouse errors-in-console audit passed. |
follow-best-practicessound-document-and-assets | issues | high | The images primitive found 7 images without dimensions, 72 below-fold images without lazy loading, 61 without srcset, 16 legacy-format images, and 25 missing alt attributes. F13 medium: Image delivery and semantics are inconsistent. |
follow-best-practicesbrowser-platform-hygiene | pass | high | Lighthouse best-practices score is 1.0 and no permission prompt appeared at browser level during load. |
be-discoverabletitle-and-description | pass | high | Homepage, section, article, and search have descriptive titles; homepage/section/article expose descriptions. |
be-discoverablecrawlable-and-mobile-friendly | pass | high | Real href links, viewport meta, a crawlable robots policy for search engines, and responsive homepage/article evidence were observed. |
be-discoverablecanonical-and-indexing-signals | pass | high | Homepage/section/article expose canonical URLs, return successful statuses, and are represented in sitemap indexes without accidental noindex. |
be-discoverablestructured-and-shareable-metadata | pass | high | Article exposes NewsArticle JSON-LD plus matching Open Graph title, description, URL, type, and image metadata. |
be-private-and-securesecure-transport-and-headers | issues | high | Headers probe found no CSP, frame protection, Referrer-Policy, or Permissions-Policy. Cookie audit found 14 cookies classed insecure, including non-Secure and SameSite=None values; HSTS and nosniff are present. F15 high: Browser security policies and cookie flags are incomplete. |
be-private-and-securedata-minimisation-and-third-parties | issues | high | HAR attributes 759,325 of 1,235,913 transferred bytes (61%) to third parties; tracker capture found 19 third-party origins and known Facebook, Google, Outbrain and other trackers. F16 high: Third-party tracking dominates transferred bytes. |
be-private-and-securein-context-permissions-and-modern-auth | pass | high | No browser permission prompt fired during capture; authentication is not part of the public news-reading core flow. |
be-private-and-securedefensive-browser-policies | issues | high | Headers probe found no CSP, frame protection, Referrer-Policy, or Permissions-Policy. Cookie audit found 14 cookies classed insecure, including non-Secure and SameSite=None values; HSTS and nosniff are present. F15 high: Browser security policies and cookie flags are incomplete. |
be-resilientprogressive-enhancement | pass | high | Discoverability comparison found 100% rendered-content coverage in raw server HTML and no JavaScript shell. |
be-resilientresilient-runtime-behaviour | pass | high | Menus, topic strips, search and recovery states rendered usable across tested mobile templates; service worker is registered. |
be-resilientoffline-and-installable | pass | high | A valid manifest with standalone display and 192/512 icons is linked, and a service-worker registration controls the origin. |
be-resilientnetwork-and-http-failure-states | pass | high | A real HTTP 404 returns status 404 and offers explanatory copy, search, home, live, TV and radio recovery actions. |
be-internationalisedlang-dir-and-logical-properties | pass | high | html lang is fr and rendered CSS includes logical inline properties; French reading order is correct. |
be-internationalisedlocale-aware-data | pass | medium | Article publication date, time, duration and French typography are rendered in the declared fr locale. |
be-internationalisedtime-zone-correctness | not-applicable | high | The representative public-news pages do not coordinate user events across time zones or accept partial-time input; no time-zone-sensitive flow applies. |
be-trustworthyno-dark-patterns | issues | medium | Search-result DOM starts with a notification activation panel and screenshots show it over unrelated tasks; the user did not initiate a notification flow. F17 medium: The notification nudge is shown without task context. |
be-trustworthyhumane-error-handling | pass | high | Search uses a labelled native search input; newsletter email is labelled, required, and relies on native validation semantics. |
be-trustworthytrustworthy-input-assistance | pass | high | Newsletter email field has autocomplete=email and a visible label; search has a visible label. |
be-trustworthysafe-commercial-and-account-flows | not-applicable | high | No checkout, subscription purchase, consent purchase, authentication, or account-management journey is part of the representative public-news scope. |
be-sustainableoptimised-assets | issues | high | The images primitive found 7 images without dimensions, 72 below-fold images without lazy loading, 61 without srcset, 16 legacy-format images, and 25 missing alt attributes. F13 medium: Image delivery and semantics are inconsistent. |
be-sustainableno-wasteful-work | issues | high | HAR attributes 759,325 of 1,235,913 transferred bytes (61%) to third parties; tracker capture found 19 third-party origins and known Facebook, Google, Outbrain and other trackers. F16 high: Third-party tracking dominates transferred bytes. |
be-sustainablethird-party-and-media-budget | issues | high | HAR attributes 759,325 of 1,235,913 transferred bytes (61%) to third parties; tracker capture found 19 third-party origins and known Facebook, Google, Outbrain and other trackers. F16 high: Third-party tracking dominates transferred bytes. |
be-agent-readystructured-agent-capabilities | issues | high | robots.txt disallows GPTBot, ChatGPT-User, ClaudeBot, Claude-Web, PerplexityBot and other AI agents, while Lighthouse agentic-browsing score is 0.33; server-rendered content itself has 100% crawler coverage. F14 medium: The public news corpus explicitly blocks major AI agents and offers no structured agent capability. |
be-agent-readyon-device-inference | not-applicable | high | No user task on the tested news-reading/search surfaces requires on-device generation or summarisation; absence is not a defect for this emerging capability. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | After ten full-page scroll cycles, heap self-size rose only 173,655 bytes (0.54%) and node count 0.81%, with no unbounded trend demonstrated. |
be-memory-efficientbounded-footprint | issues | medium | Baseline heap summary contains 547,086 nodes, 2,227,476 edges, and 32,032,181 self-size bytes. Repeated full-page scroll grew self-size only 0.54%, so this is footprint rather than demonstrated leakage. F18 medium: The initial page memory/DOM footprint is large for a news landing page. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | Before/after heap summaries show no Detached* constructor among top retained constructors and only small bounded growth after repeated scrolling. |
