Coverage complete
Atomic coverage complete across 58 checks and five representative paths.
All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | The 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-preferencesrespects-reduced-motion | pass | high | Under prefers-reduced-motion: reduce, the active-animation probe reported zero animations; no auto-advance or essential motion appeared on representative pages. |
respect-user-preferencesrespects-contrast | issues | high | Lighthouse 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-interactionsview-transitions | issues | high | DOM/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-interactionsscroll-driven-animations | not-applicable | high | No parallax, scrollytelling, reveal, or other scroll-linked animation exists on the audited templates. |
implement-natural-interactionsphysical-gestures | not-applicable | high | The audited news templates expose ordinary links and scrolling, with no custom swipe, pull, draggable, or carousel gesture surface. |
provide-guided-navigationscroll-state-aware-chrome | issues | high | Screenshots 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-navigationanchored-positioning | not-applicable | high | No tooltip, menu, or popover overlay was present in the audited states. |
provide-guided-navigationdirects-attention | pass | high | Selected 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-noiseno-intrusive-interruptions | pass | high | Load-state screenshots across home, category, ranking, and article show content immediately with no consent wall, interstitial, or obscuring popup. |
maximize-content-reduce-noisesemantic-dismissible-primitives | not-applicable | high | No transient overlay, modal flow, or custom disclosure was present in the audited states. |
maximize-content-reduce-noisereduced-chrome | pass | high | Screenshots show compact global navigation and predominantly news lists/article copy; chrome does not obscure the content. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | At 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-factorcomponent-level-responsiveness | issues | high | The 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-factorinput-modality-aware | issues | high | The 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-successclear-purpose-and-primary-action | pass | high | The H1, selected news tab, category labels, ranking heading, and article headline make each page purpose and next link clear. |
support-core-task-successprimary-flow-completion | pass | high | The 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-successclear-system-state-and-recovery | pass | high | A 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-stablegood-core-web-vitals | issues | high | Lighthouse 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-stablevisual-stability | pass | high | Layout 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-stableefficient-main-thread | issues | high | Lighthouse 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-stableefficient-resource-delivery | issues | high | HAR 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-stabletrim-unused-and-duplicate-code | issues | high | Lighthouse 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-inclusivenames-roles-labels | issues | high | axe 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-inclusivesufficient-contrast | issues | high | Lighthouse 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-inclusivestructure-and-focus | issues | high | axe 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-inclusivelegible-text | issues | high | All 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-inclusivezoom-reflow-targets-and-media | issues | high | See linked finding. F16 high: The experience fails narrow reflow and includes undersized targets. |
follow-best-practicesno-console-errors | issues | high | Lighthouse 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-practicessound-document-and-assets | issues | high | The 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-practicesbrowser-platform-hygiene | issues | high | Lighthouse 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-discoverabletitle-and-description | pass | high | Home and article probes found unique descriptive titles and populated descriptions that match the visible Japanese content. |
be-discoverablecrawlable-and-mobile-friendly | issues | high | Recon 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-discoverablecanonical-and-indexing-signals | issues | high | The 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-discoverablestructured-and-shareable-metadata | issues | high | The 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-securesecure-transport-and-headers | issues | high | The 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-securedata-minimisation-and-third-parties | issues | high | Tracker 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-securein-context-permissions-and-modern-auth | not-applicable | high | No permission prompt fired on load, and no authentication surface exists in the representative public news-reading paths. |
be-private-and-securedefensive-browser-policies | issues | high | Header 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-resilientprogressive-enhancement | pass | high | Discoverability 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-resilientresilient-runtime-behaviour | pass | high | Representative navigation/list/article templates loaded without clipped overlay state; links remain ordinary server navigations and no fragile overlay/async control was found. |
be-resilientoffline-and-installable | not-applicable | high | No manifest or service worker exists, but this continuously updated public news portal is primarily a content MPA rather than an install-oriented application. |
be-resilientnetwork-and-http-failure-states | pass | high | The tested missing route provides an explanatory state and direct recovery link instead of a blank shell or infinite spinner. |
be-internationalisedlang-dir-and-logical-properties | pass | high | All templates declare valid `lang="ja"`; Japanese reading order is correct for the deliberately Japanese service. |
be-internationalisedlocale-aware-data | issues | high | Article 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-internationalisedtime-zone-correctness | not-applicable | high | No scheduled cross-zone event, user-entered time, recurrence, or DST-sensitive flow exists in the representative news-reading paths. |
be-trustworthyno-dark-patterns | pass | high | Load and article/listing screenshots show no confirmshaming, forced continuity, consent nag, disguised control, or hidden pricing/account commitment. |
be-trustworthyhumane-error-handling | not-applicable | high | The audited core flow has no user-data form; the only form is a basic search and no submitted invalid-data workflow was required. |
be-trustworthytrustworthy-input-assistance | not-applicable | high | The only text input is generic site search; address, payment, authentication, and profile autofill are not relevant. |
be-trustworthysafe-commercial-and-account-flows | not-applicable | high | No checkout, subscription, consent choice, sign-in, or account-management flow is part of this public news-reading surface. |
be-sustainableoptimised-assets | issues | high | All 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-sustainableno-wasteful-work | issues | high | HAR 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-sustainablethird-party-and-media-budget | issues | high | HAR 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-readystructured-agent-capabilities | not-applicable | high | robots.txt explicitly blocks major AI agents and the site exposes no WebMCP tools, indicating no intended agent-facing capability. |
be-agent-readyon-device-inference | not-applicable | high | No summarisation, translation, generative, or other inference feature is offered in the audited news-reading experience. |
be-memory-efficientno-leak-under-repeated-interaction | not-applicable | high | The 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-efficientbounded-footprint | pass | high | The 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-efficientno-detached-dom-or-unbounded-listeners | pass | high | The single-state heap constructor summary showed no Detached* constructor among dominant populations; no repeated long-lived interaction exists on these MPA templates. |
