All 58 atomic check outcomes

Principle / checkStatusConfidenceEvidence or reason
respect-user-preferences
respects-color-scheme
issueshighThe dark-emulated screenshot is pixel-identical in appearance and file size to the light capture; white surfaces and dark text remain unchanged.
F01 medium: The site ignores the user’s dark color-scheme preference.
respect-user-preferences
respects-reduced-motion
passhighUnder prefers-reduced-motion: reduce, the active-animation probe reported zero animations; no auto-advance or essential motion appeared on representative pages.
respect-user-preferences
respects-contrast
issueshighLighthouse measured date/time text at 2.95:1 (#969696 on white), while the prefers-contrast: more capture retained the same palette.
F02 medium: Low-contrast metadata does not adapt for contrast preferences.
implement-natural-interactions
view-transitions
issueshighDOM/CSS probe found no `view-transition` CSS on this multi-page news site; representative category, ranking, and article navigations perform full abrupt swaps.
F03 low: Cross-document navigation swaps abruptly.
implement-natural-interactions
scroll-driven-animations
not-applicablehighNo parallax, scrollytelling, reveal, or other scroll-linked animation exists on the audited templates.
implement-natural-interactions
physical-gestures
not-applicablehighThe audited news templates expose ordinary links and scrolling, with no custom swipe, pull, draggable, or carousel gesture surface.
provide-guided-navigation
scroll-state-aware-chrome
issueshighScreenshots show long multi-section pages, while CSS inspection found no scroll-state container-query or progress treatment; page chrome does not communicate reading position.
F04 low: The long news pages provide no scroll-state-aware navigation or progress cue.
provide-guided-navigation
anchored-positioning
not-applicablehighNo tooltip, menu, or popover overlay was present in the audited states.
provide-guided-navigation
directs-attention
passhighSelected category tabs use a strong blue state, breadcrumbs identify location on inner pages, and content headings clearly cue the destination after navigation.
maximize-content-reduce-noise
no-intrusive-interruptions
passhighLoad-state screenshots across home, category, ranking, and article show content immediately with no consent wall, interstitial, or obscuring popup.
maximize-content-reduce-noise
semantic-dismissible-primitives
not-applicablehighNo transient overlay, modal flow, or custom disclosure was present in the audited states.
maximize-content-reduce-noise
reduced-chrome
passhighScreenshots show compact global navigation and predominantly news lists/article copy; chrome does not obscure the content.
adapt-to-the-form-factor
responsive-no-horizontal-scroll
issueshighAt a requested 360×800 viewport, layout metrics reported `innerWidth: 769`, visual scale 0.46875, and the screenshot shows desktop columns and tiny text compressed into the screen. The viewport meta is only `width=device-width`.
F05 high: Mobile viewports receive a scaled-down 768px tablet layout.
adapt-to-the-form-factor
component-level-responsiveness
issueshighThe probe found no `@container`; the same cards stay in tablet-scale columns on 360px instead of reflowing for the narrow container.
F06 medium: Repeated news components do not respond to their available container.
adapt-to-the-form-factor
input-modality-aware
issueshighThe focus probe repeatedly returned outline style `none`; Lighthouse also found 16px-tall publisher links with less than the 24px WCAG 2.2 target-size floor. The scaled tablet viewport further shrinks effective controls.
F07 high: Keyboard focus is suppressed and some touch targets are undersized.
support-core-task-success
clear-purpose-and-primary-action
passhighThe H1, selected news tab, category labels, ranking heading, and article headline make each page purpose and next link clear.
support-core-task-success
primary-flow-completion
passhighThe representative flow from listing/category to a direct article URL completed and exposed the full article plus publisher/context links without an account wall.
support-core-task-success
clear-system-state-and-recovery
passhighA nonexistent route displays a specific Japanese not-found explanation, preserved global navigation, and a prominent “ニューストップへ” recovery link.
be-fast-and-stable
good-core-web-vitals
issueshighLighthouse measured FCP 7.4s, LCP 11.6s, Speed Index 13.5s, TBT 360ms, and a performance score of 47. The separate trace still measured LCP 3.35s, above the 2.5s good threshold.
F08 high: Cold mobile loading is far outside the good LCP range.
be-fast-and-stable
visual-stability
passhighLayout observation measured CLS 0.00017 on home and 0 on ranking; Lighthouse measured CLS 0.009, all within the ≤0.1 good range.
be-fast-and-stable
efficient-main-thread
issueshighLighthouse reported 5.3s main-thread work, 3.1s JavaScript execution, TTI 28s, and TBT 360ms; the trace recorded a 79ms long task.
F09 high: Third-party and legacy JavaScript consume substantial main-thread time.
be-fast-and-stable
efficient-resource-delivery
issueshighHAR plus DOM confirmation found six classic scripts in `<head>` with neither async nor defer, including 282KB `swiper.js`; Lighthouse estimated 4.64s render-blocking savings and flagged cache, font-display, HTTP, and dependency-tree issues.
F10 high: Parser-blocking scripts and weak delivery delay content.
be-fast-and-stable
trim-unused-and-duplicate-code
issueshighLighthouse estimated 1,392KiB unused JavaScript, 157KiB unused CSS, 130KiB legacy JavaScript, and 82KiB unminified JavaScript; HAR attributes 1.30MB to scripts.
F11 medium: The page ships large amounts of unused and legacy code.
be-inclusive
names-roles-labels
issueshighaxe reported a critical `label` violation for `input#search`; Lighthouse independently found unlabeled search input `#queryft`.
F12 high: A search field lacks an accessible label.
be-inclusive
sufficient-contrast
issueshighLighthouse measured repeated 12px timestamp text at 2.95:1 against white, below the required 4.5:1.
F13 medium: News timestamps fail WCAG contrast.
be-inclusive
structure-and-focus
issueshighaxe found skipped heading levels and non-unique landmarks; the probe ends an H1/H2/H3 sequence with H4 and found no visible computed outline on focused controls.
F14 medium: Heading/landmark structure and focus presentation are inconsistent.
be-inclusive
legible-text
issueshighAll representative 360px screenshots show the 768px tablet design scaled to roughly 47%, producing very small article metadata, navigation, and list copy.
F15 high: Text is not legible at a narrow mobile viewport.
be-inclusive
zoom-reflow-targets-and-media
issueshighSee linked finding.
F16 high: The experience fails narrow reflow and includes undersized targets.
follow-best-practices
no-console-errors
issueshighLighthouse captured repeated CORS failures to `hb.adingo.jp` plus unresolved/failed resources; the HAR also recorded ORB-blocked scripts.
F17 medium: Advertising requests produce repeated console/network errors.
follow-best-practices
sound-document-and-assets
issueshighThe images primitive found all 15 images missing at least one dimension and all 15 served as PNG/JPEG; eight below-fold images were not lazy-loaded.
F18 medium: Image markup omits intrinsic dimensions and uses only legacy formats.
follow-best-practices
browser-platform-hygiene
issueshighLighthouse found three deprecations, including the main-frame unload listener, and confirmed that handler blocks BFCache restoration; source-map and Inspector Issues audits also failed.
F19 medium: Deprecated APIs and an unload handler reduce platform compatibility.
be-discoverable
title-and-description
passhighHome and article probes found unique descriptive titles and populated descriptions that match the visible Japanese content.
be-discoverable
crawlable-and-mobile-friendly
issueshighRecon found many article links using `/redirector?...`; robots.txt disallows `/redirector` for all crawlers. Some header actions also expose empty href values.
F20 high: Primary story links route through URLs explicitly blocked from crawling.
be-discoverable
canonical-and-indexing-signals
issueshighThe home probe found no `rel=canonical`, although the page redirects to `?redirect=1`; the article template does provide a correct canonical and sitemaps are present.
F21 low: The homepage lacks a canonical URL.
be-discoverable
structured-and-shareable-metadata
issueshighThe article has accurate title, description, canonical, and Open Graph values, but the probe found zero JSON-LD blocks and no semantic `<time datetime>` values.
F22 medium: Article pages omit NewsArticle structured data.
be-private-and-secure
secure-transport-and-headers
issueshighThe headers primitive found no CSP, HSTS, nosniff, frame protection, Referrer-Policy, or Permissions-Policy. Cookie audit found five insecure cookies, including three 400-day analytics cookies.
F23 high: Security headers are absent and several cookies are not Secure.
be-private-and-secure
data-minimisation-and-third-parties
issueshighTracker evidence found 13 third-party origins and Google Analytics, GTM, Facebook, and Google ads; Lighthouse observed 18 third-party cookies. HAR attributes 52/55 requests and 1.61MB/1.63MB transferred bytes to third parties.
F24 high: The page starts a broad tracking/advertising footprint before any visible choice.
be-private-and-secure
in-context-permissions-and-modern-auth
not-applicablehighNo permission prompt fired on load, and no authentication surface exists in the representative public news-reading paths.
be-private-and-secure
defensive-browser-policies
issueshighHeader inspection found no clickjacking protection, Referrer-Policy, Permissions-Policy, CSP/Trusted Types foundation, or HSTS.
F25 medium: Browser-enforced defensive policies are not configured.
be-resilient
progressive-enhancement
passhighDiscoverability fetched HTTP 200 raw HTML with title, H1, description, and 100% measured home content coverage without JavaScript; article raw HTML was substantial and crawler screenshot retained content.
be-resilient
resilient-runtime-behaviour
passhighRepresentative navigation/list/article templates loaded without clipped overlay state; links remain ordinary server navigations and no fragile overlay/async control was found.
be-resilient
offline-and-installable
not-applicablehighNo manifest or service worker exists, but this continuously updated public news portal is primarily a content MPA rather than an install-oriented application.
be-resilient
network-and-http-failure-states
passhighThe tested missing route provides an explanatory state and direct recovery link instead of a blank shell or infinite spinner.
be-internationalised
lang-dir-and-logical-properties
passhighAll templates declare valid `lang="ja"`; Japanese reading order is correct for the deliberately Japanese service.
be-internationalised
locale-aware-data
issueshighArticle metadata is rendered as `7/19(日) 11:04`; the article probe found no `<time datetime>` values, preventing unambiguous machine/locale interpretation.
F26 medium: Publication dates are presented as unstructured locale-specific strings.
be-internationalised
time-zone-correctness
not-applicablehighNo scheduled cross-zone event, user-entered time, recurrence, or DST-sensitive flow exists in the representative news-reading paths.
be-trustworthy
no-dark-patterns
passhighLoad and article/listing screenshots show no confirmshaming, forced continuity, consent nag, disguised control, or hidden pricing/account commitment.
be-trustworthy
humane-error-handling
not-applicablehighThe audited core flow has no user-data form; the only form is a basic search and no submitted invalid-data workflow was required.
be-trustworthy
trustworthy-input-assistance
not-applicablehighThe only text input is generic site search; address, payment, authentication, and profile autofill are not relevant.
be-trustworthy
safe-commercial-and-account-flows
not-applicablehighNo checkout, subscription, consent choice, sign-in, or account-management flow is part of this public news-reading surface.
be-sustainable
optimised-assets
issueshighAll 15 audited images are JPEG/PNG, eight below-fold images are eager, and every image lacks at least one intrinsic dimension; Lighthouse estimated 156KiB image-delivery savings.
F27 medium: Image delivery misses basic efficiency controls.
be-sustainable
no-wasteful-work
issueshighHAR shows 1.30MB of scripts and failed ORB/analytics requests; Lighthouse reports 1,392KiB unused JS and 3.1s execution time.
F28 medium: Large optional scripts and failed ad requests perform wasteful work.
be-sustainable
third-party-and-media-budget
issueshighHAR recorded 1.61MB of 1.63MB transferred from third-party origins in this capture; Lighthouse’s broader run reached 3,491KiB and identified extensive tracking/cookie activity.
F29 high: Third-party code dominates the page budget.
be-agent-ready
structured-agent-capabilities
not-applicablehighrobots.txt explicitly blocks major AI agents and the site exposes no WebMCP tools, indicating no intended agent-facing capability.
be-agent-ready
on-device-inference
not-applicablehighNo summarisation, translation, generative, or other inference feature is offered in the audited news-reading experience.
be-memory-efficient
no-leak-under-repeated-interaction
not-applicablehighThe audited templates are server-navigated content pages with no modal, SPA route cycle, editor, or infinite feed interaction suitable for a meaningful ten-cycle leak test.
be-memory-efficient
bounded-footprint
passhighThe steady home snapshot reported 313,587 heap nodes and 16.85MB self size; Performance memory reported about 14.0MB used heap, proportionate to this content page.
be-memory-efficient
no-detached-dom-or-unbounded-listeners
passhighThe single-state heap constructor summary showed no Detached* constructor among dominant populations; no repeated long-lived interaction exists on these MPA templates.
