All 58 atomic check outcomes

Principle / checkStatusConfidenceEvidence or reason
respect-user-preferences
respects-color-scheme
issueshighThe dark/reduced screenshot remains a white/cream light theme; the probe reports colorScheme "normal" and no authored prefers-color-scheme rule.
F-01 medium: Dark preference is ignored
respect-user-preferences
respects-reduced-motion
passhighThe reduced-motion probe reported zero active animations; no auto-advance or essential animated flow was present.
respect-user-preferences
respects-contrast
passhighText, links, controls and consent actions remain visibly differentiated under forced-colors active.
implement-natural-interactions
view-transitions
issueshighThe CSS probe found no authored view-transition rule or startViewTransition use across this multi-page site.
F-02 low: Route changes are abrupt
implement-natural-interactions
scroll-driven-animations
not-applicablehighNo parallax, scrollytelling, reveal animation or other scroll-linked motion exists to implement declaratively.
implement-natural-interactions
physical-gestures
passmediumCore pages rely on native page scrolling and links; no custom swipe/pointer interaction was found fighting platform behavior.
provide-guided-navigation
scroll-state-aware-chrome
issueshighThe 8,518px homepage and 5,816px article use fixed shared chrome, but the CSS probe found no scroll-state or scroll-timeline behavior.
F-03 low: Long pages provide static rather than scroll-aware navigation
provide-guided-navigation
anchored-positioning
not-applicablehighNo tooltip/popover/menu requiring element-relative anchor positioning was present on the audited core paths.
provide-guided-navigation
directs-attention
passmediumArticle breadcrumbs, descriptive links, red active navigation and direct result links give users visible orientation.
maximize-content-reduce-noise
no-intrusive-interruptions
issueshighDesktop, homepage mobile, results, and statistics screenshots all show a modal consent wall covering the lottery results or form before interaction.
F-04 high: Consent wall obscures the primary content on first load
maximize-content-reduce-noise
semantic-dismissible-primitives
issueshighDOM recon found multiple `div[role=dialog]` consent surfaces rather than native `<dialog>`, while the modal injects hundreds of vendor headings into the document.
F-05 medium: Consent UI is custom dialog chrome
maximize-content-reduce-noise
reduced-chrome
issueshighThe consent interface lists 210 partners and the tracker probe sees 17 third-party origins; article Lighthouse also loads in-article advertising controls around the content.
F-06 medium: Advertising and consent chrome compete with content
adapt-to-the-form-factor
responsive-no-horizontal-scroll
issueshighAt a 390px visual viewport, article layout metrics report scrollWidth/client layout width 496px and horizontalOverflowPx 106.
F-07 high: Article template overflows mobile by 106px
adapt-to-the-form-factor
component-level-responsiveness
issueshighThe article CSS probe found no authored `@container` rule despite cards, sidebars and result tables being reused across narrow and wide regions.
F-08 medium: Shared components only use viewport-level adaptation
adapt-to-the-form-factor
input-modality-aware
issueshighThe focused first link computed to `outline-style:none`; the probe also found multiple visible targets under 24px high.
F-09 medium: Focus and target sizing are inconsistent
support-core-task-success
clear-purpose-and-primary-action
passhighThe H1 and result tables immediately identify current three-region lottery results, with direct regional result links.
support-core-task-success
primary-flow-completion
passhighCurrent results are readable without sign-in and regional/history links use real destinations; the primary lookup does not dead-end.
support-core-task-success
clear-system-state-and-recovery
passhighThe server returns HTTP 404 with a clear bilingual not-found message, home link and alternative region links.
be-fast-and-stable
good-core-web-vitals
issueshighMobile Lighthouse measured LCP 11.1s, TTI 11.5s and performance 67; the independent trace measured LCP 3.68s.
F-10 high: Homepage LCP is far outside the good range
be-fast-and-stable
visual-stability
passhighCLS was 0.013 home, 0.060 results, 0.028 stats and 0.063 article, all within the good threshold.
be-fast-and-stable
efficient-main-thread
issueshighArticle Lighthouse measured 530ms TBT and 28.6s TTI; mobile layout observed 90ms and 52ms long tasks.
F-11 high: Article scripting blocks interaction
be-fast-and-stable
efficient-resource-delivery
issueshighHAR recorded 2.44MB, including 2.21MB of scripts; 2.41MB came from third parties and a 414KB Prebid script was uncompressed.
F-12 high: Third-party script delivery dominates the load
be-fast-and-stable
trim-unused-and-duplicate-code
issueshighLighthouse estimated 624KiB unused JS on home and 2,034KiB on the article, including duplicated gtag/ad stacks.
F-13 high: Large amounts of shipped JavaScript are unused
be-inclusive
names-roles-labels
issueshighArticle Lighthouse found six ad links with no discernible name; the statistics probe found date/select/button controls with no associated labels.
F-14 medium: Some article and statistics controls lack accessible names
be-inclusive
sufficient-contrast
passmediumLighthouse accessibility scored 100 on home and 97 on article without a reported contrast failure; forced colors remains readable.
be-inclusive
structure-and-focus
issueshighThe page probe found no visible outline on the first focused link and consent markup injects several H1s plus hundreds of vendor H2s into the document.
F-15 medium: Injected consent structure and focus styling weaken navigation
be-inclusive
legible-text
passhighArticle body uses large black text on white, clear hierarchy and comfortable line spacing in the visible reading column.
be-inclusive
zoom-reflow-targets-and-media
issueshighThe article has 106px horizontal overflow at 390px, and the interaction probe found multiple targets under 24px high.
F-16 high: Mobile reflow and target sizing fail on the article
follow-best-practices
no-console-errors
issueshighLighthouse reported “Not signed in with the identity provider” as a console error on home and article.
F-17 low: Identity integration logs a browser error
follow-best-practices
sound-document-and-assets
issueshighThe image primitive found 21 of 25 images without width/height; 10 below-fold images were not lazy-loaded.
F-18 medium: Most images lack intrinsic dimensions
follow-best-practices
browser-platform-hygiene
issueshighLighthouse failed notification-on-start on both representative pages; article ads also triggered a deprecated Shared Storage warning.
F-19 high: The page requests notifications on load
be-discoverable
title-and-description
passhighHome and article have descriptive unique titles and meta descriptions; Lighthouse passes both title and description audits.
be-discoverable
crawlable-and-mobile-friendly
issueshighLighthouse found `a#curr_living_btn` labelled “➜ Xem ngay” with `href="javascript:void(0)"`.
F-20 medium: A visible action uses a non-crawlable JavaScript URL
be-discoverable
canonical-and-indexing-signals
passhighBoth pages return 200, homepage has canonical URL, robots is valid and sitemap.xml is available without accidental noindex.
be-discoverable
structured-and-shareable-metadata
passhighHomepage exposes Organization and WebSite JSON-LD plus Open Graph/Twitter title, description and image matching visible content.
be-private-and-secure
secure-transport-and-headers
issueshighHTTPS is used, but headers lack CSP, HSTS and nosniff; all seven observed first-party cookies lacked Secure and used SameSite=None.
F-21 high: Core transport defenses and cookie flags are missing
be-private-and-secure
data-minimisation-and-third-parties
issueshighTracker evidence found 17 third-party origins and six known trackers; HAR attributes 51/55 requests and 2.41/2.44MB to third parties before a consent choice.
F-22 high: The initial page has an excessive tracking footprint
be-private-and-secure
in-context-permissions-and-modern-auth
issueshighLighthouse identified a notification permission request on page load. The sign-in surface exists, but no passkey flow was exposed in the audited public path.
F-23 high: Notification permission is requested out of context
be-private-and-secure
defensive-browser-policies
issueshighHeader audit found no HSTS, CSP/frame-ancestors, nosniff, Referrer-Policy or Permissions-Policy; only X-Frame-Options SAMEORIGIN was present.
F-24 high: Browser-enforced defensive policies are incomplete
be-resilient
progressive-enhancement
passhighCore results and article text are server-rendered without JS; home raw/rendered token coverage is 72% and neither page is a JS shell.
be-resilient
resilient-runtime-behaviour
passmediumResults, statistics, article and 404 pages render useful content; no clipped core overlay/menu or blank runtime state was observed.
be-resilient
offline-and-installable
not-applicablehighThis public results/content site is not a long-lived app requiring offline use; a manifest exists but no service-worker registration was found.
be-resilient
network-and-http-failure-states
passhighThe server returns a real 404 and a useful recovery page with a homepage link and suggested result destinations.
be-internationalised
lang-dir-and-logical-properties
passhighThe document declares `lang="vi"`; Vietnamese text renders in the expected LTR reading order.
be-internationalised
locale-aware-data
not-applicablehighThe service deliberately targets Vietnamese lottery data in one locale and exposes no currency or user-selectable locale requiring cross-locale formatting.
be-internationalised
time-zone-correctness
not-applicablehighPublished draw/article dates are local Vietnamese dates; no cross-time-zone scheduling or user-entered time flow is present.
be-trustworthy
no-dark-patterns
passmediumConsent and Do not consent are equally prominent and the public result flow does not force account creation, purchase or continuity.
be-trustworthy
humane-error-handling
not-applicablemediumThe audited public statistics flow has no required free-form submission or validation error state; login was outside the selected public core flow.
be-trustworthy
trustworthy-input-assistance
issueshighThe statistics form probe found an unlabeled text date, unlabeled select and button, all with empty autocomplete values.
F-25 medium: Statistics inputs provide little programmatic assistance
be-trustworthy
safe-commercial-and-account-flows
not-applicablehighNo checkout, subscription, payment, account-management or sensitive account action is part of the audited public lottery lookup journey.
be-sustainable
optimised-assets
issueshighImage evidence reports 21 missing dimensions, 10 below-fold images not lazy-loaded and two images without responsive sources.
F-26 low: Image loading metadata is incomplete
be-sustainable
no-wasteful-work
issueshighHAR shows 51 third-party requests and 2.21MB of scripts for a mostly text/table page; Lighthouse estimates up to 2MB unused JS on the article.
F-27 high: Background advertising work is disproportionate to the core page
be-sustainable
third-party-and-media-budget
issueshigh2.41MB of 2.44MB transferred on home was third party; top costs were tag manager, Prebid, ads, MGID and consent code.
F-28 high: Third-party bytes overwhelm first-party content
be-agent-ready
structured-agent-capabilities
not-applicablehighThe site exposes public informational content rather than an agent-facing transaction/tool surface; WebMCP is not necessary for its declared experience.
be-agent-ready
on-device-inference
not-applicablehighNo summarization, generation or translation task is offered where on-device inference would be an expected product capability.
be-memory-efficient
no-leak-under-repeated-interaction
passlowSelf size changed from 31.93MB to 32.72MB across separate fresh sessions; this does not establish unbounded retained growth, but confidence is low because third-party load variance dominates.
be-memory-efficient
bounded-footprint
issueshighBaseline heap summary contains 575,957 nodes and 31.9MB self size, while the DOM probe counts 6,798 elements; third-party ad/consent code dominates the complexity.
F-29 medium: Heap footprint is high for a mostly text/table page
be-memory-efficient
no-detached-dom-or-unbounded-listeners
passmediumNeither heap top-constructor list contains Detached* nodes; the runtime probe found one inline listener-bearing element and no evidence of accumulating detached DOM.
