All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | Under prefers-color-scheme: dark, the probe reports color-scheme: normal and body background rgb(255,255,255); the dark screenshot remains light. F01 medium: The site does not adapt to dark color preference. |
respect-user-preferencesrespects-reduced-motion | issues | high | With prefers-reduced-motion: reduce active, getAnimations() still reports a running 20,000 ms animation. F02 medium: The auto-advancing hero continues animating when reduced motion is requested. |
respect-user-preferencesrespects-contrast | issues | high | The prefers-contrast: more probe matched the condition but found no prefers-contrast or forced-colors CSS. F03 low: No high-contrast preference styling is present. |
implement-natural-interactionsview-transitions | issues | high | The feature probe found no authored view-transition CSS while the page uses a Slick carousel with 80 cloned slides and a running 20-second animation. F04 medium: Carousel and route changes rely on abrupt or JavaScript-driven motion rather than preference-aware platform transitions. |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No scroll-linked parallax, scrollytelling, or reveal behavior was observed on representative pages, so there is no scroll-linked animation implementation to judge. |
implement-natural-interactionsphysical-gestures | issues | high | The feature probe found no authored view-transition CSS while the page uses a Slick carousel with 80 cloned slides and a running 20-second animation. F04 medium: Carousel and route changes rely on abrupt or JavaScript-driven motion rather than preference-aware platform transitions. |
provide-guided-navigationscroll-state-aware-chrome | pass | high | After scrolling 1000px, the primary nav remained at the top while the header moved away, preserving orientation without covering content. |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip or edge-sensitive anchored popover was present in the representative content, listing, article, or contact paths. |
provide-guided-navigationdirects-attention | pass | high | Article screenshots show a visible breadcrumb trail and grouped share/follow actions that preserve location and next steps. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | The tracker audit saw 13 third-party origins and six known tracker domains. The Vietnamese fresh load starts trackers without a visible consent choice, while English is covered by a consent modal naming 210 partners. F11 high: Tracking is extensive and consent is inconsistent across locale entry points. |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | The tracker audit saw 13 third-party origins and six known tracker domains. The Vietnamese fresh load starts trackers without a visible consent choice, while English is covered by a consent modal naming 210 partners.

be-private-and-securesecure-transport-and-headers | issues | high | HTTPS is used, but the headers audit found no CSP, HSTS, nosniff, clickjacking, Referrer-Policy, or Permissions-Policy. All five observed cookies lacked Secure and used SameSite=None. F10 high: Core browser security headers are absent and cookies use weak attributes. |
be-private-and-securedata-minimisation-and-third-parties | issues | high | The tracker audit saw 13 third-party origins and six known tracker domains. The Vietnamese fresh load starts trackers without a visible consent choice, while English is covered by a consent modal naming 210 partners.

be-resilientprogressive-enhancement | pass | high | Discoverability found 98% raw/rendered content overlap, title/H1/description in raw HTML, and no JS shell. |
be-resilientresilient-runtime-behaviour | issues | high | The English page correctly sets lang=en, but keeps the Vietnamese document title. Its consent panel overflows the mobile viewport and clips controls/text. F13 medium: Localized metadata and the English consent layout are not fully adapted. |
be-resilientoffline-and-installable | not-applicable | high | This is a public news/content publication rather than an install-oriented application; offline installation is not required for the primary reading task. |
be-resilientnetwork-and-http-failure-states | pass | high | A nonexistent route returned HTTP 404 with an actionable recovery page and home link. |
be-internationalisedlang-dir-and-logical-properties | issues | high | The English page correctly sets lang=en, but keeps the Vietnamese document title. Its consent panel overflows the mobile viewport and clips controls/text. F13 medium: Localized metadata and the English consent layout are not fully adapted. |
be-internationalisedlocale-aware-data | pass | high | Vietnamese article dates use day/month/year and localized pages expose locale-specific content and hreflang alternatives. |
be-internationalisedtime-zone-correctness | not-applicable | high | Representative pages display publication dates but expose no scheduled cross-time-zone event or user-entered time workflow requiring DST/time-zone conversion. |
be-trustworthyno-dark-patterns | pass | high | The inspected primary reading and contact paths showed no forced continuity, disguised ads, confirmshaming, or hidden pricing. |
be-trustworthyhumane-error-handling | issues | high | Inputs have empty name/autocomplete and required=false. Empty submission sets aria-invalid=true, but exposes no validation message or visible error text in the captured body. F12 medium: The contact form lacks input metadata and gives weak empty-submission feedback. |
be-trustworthytrustworthy-input-assistance | issues | high | Inputs have empty name/autocomplete and required=false. Empty submission sets aria-invalid=true, but exposes no validation message or visible error text in the captured body. F12 medium: The contact form lacks input metadata and gives weak empty-submission feedback. |
be-trustworthysafe-commercial-and-account-flows | issues | high | The exercised login screen shows Google, Apple, and email entry; no passkey option is visible. F14 medium: Authentication offers social/email-password entry but no visible phishing-resistant passkey path. |
be-sustainableoptimised-assets | issues | high | The image audit found 44/100 without dimensions, 57 without srcset, and 47 in legacy formats; Lighthouse also failed unsized-images. F09 medium: Images are not consistently dimensioned, responsive, or efficiently encoded. |
be-sustainableno-wasteful-work | issues | high | HAR transferred 7.25MB, including 3.58MB images and 1.95MB media, while the tracker probe found 13 third-party origins and the hero auto-animates. F15 medium: Resource use is disproportionate for a news homepage. |
be-sustainablethird-party-and-media-budget | issues | high | HAR transferred 7.25MB, including 3.58MB images and 1.95MB media, while the tracker probe found 13 third-party origins and the hero auto-animates. F15 medium: Resource use is disproportionate for a news homepage. |
be-agent-readystructured-agent-capabilities | pass | high | For this non-transactional publication, 98% of content is available without JS and NewsArticle/Organization/Breadcrumb JSON-LD gives agents structured, scrape-free content metadata. |
be-agent-readyon-device-inference | not-applicable | high | The site provides published editorial content but no user-facing summarization or generative task where built-in inference is necessary. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | After ten real Next-carousel activations in one session, DOM elements and slide count remained exactly stable at 3,670 and 80; heap rose about 3.1MB before collection, which does not demonstrate unbounded retained growth. |
be-memory-efficientbounded-footprint | issues | high | Heap summaries contain roughly 631k-641k nodes and 39.5-41.5MB self size; the DOM probe found 3,670 elements and 80 carousel slides. F16 medium: The homepage memory footprint is high for a content page. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | low | Across ten carousel activations, live DOM and slide populations did not grow; the two heap totals changed modestly rather than multiplying. Confidence is limited because listener internals were not enumerable. |
