All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | The prefers-color-scheme: dark screenshot is pixel-identical to the light screenshot; the page instead exposes a manual toggle. F01 medium: System dark-mode preference is ignored |
respect-user-preferencesrespects-reduced-motion | pass | high | No animations or non-zero transitions were present while prefers-reduced-motion: reduce matched. |
respect-user-preferencesrespects-contrast | issues | high | Lighthouse measured link contrast as low as 3.46:1 on the green notice and 4.19:1 for dark-theme tabs, below 4.5:1. F02 medium: Some controls and links do not preserve sufficient contrast |
implement-natural-interactionsview-transitions | issues | high | The structure probe found no view-transition CSS and the page uses ordinary MPA navigation and Bootstrap tab swaps. F03 low: Navigation and tab state swaps are abrupt |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No scroll-linked animation, parallax, reveal, or scrollytelling surface exists on the representative pages. |
implement-natural-interactionsphysical-gestures | not-applicable | high | No custom gesture-driven interaction exists; forum navigation uses native links and controls. |
provide-guided-navigationscroll-state-aware-chrome | issues | high | The mobile layout is 28,788px tall, while screenshots show static header/navigation and the DOM contains no scroll-state/container-query feature. F04 low: Very long listing pages provide no scroll-position feedback |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip, popover, or viewport-edge menu requiring anchored positioning was found. |
provide-guided-navigationdirects-attention | pass | high | Thread pages provide TOP and category breadcrumbs, and the homepage labels each list state with visible tabs. |
maximize-content-reduce-noiseno-intrusive-interruptions | pass | high | Initial desktop and mobile captures showed content immediately with no modal, consent wall, or interstitial obscuring it. |
maximize-content-reduce-noisesemantic-dismissible-primitives | not-applicable | high | No modal, disclosure, tooltip, or transient overlay was present on the representative successful pages. |
maximize-content-reduce-noisereduced-chrome | pass | high | The first viewport is dominated by recommended threads, notice text, and listing navigation rather than decorative application framing. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | pass | high | At 360x800, scrollWidth and clientWidth were both 360, horizontal overflow was 0, and a viewport meta tag was present. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | high | The live CSS probe found zero @container rules despite cards/navigation being reused in narrow and wide contexts. F05 low: Repeated components adapt only at page level |
adapt-to-the-form-factorinput-modality-aware | issues | high | The focus probe found 18 of the first 30 focusable controls below 44px in one dimension; the category link reported outline-style:none and no box shadow. F06 medium: Many controls are too small and one menu loses visible keyboard focus |
support-core-task-successclear-purpose-and-primary-action | pass | high | The title, recommended threads, category/list tabs, search control, and thread cards make the forum purpose and next actions apparent. |
support-core-task-successprimary-flow-completion | issues | high | Submitting the visible search for ドラゴンボール redirected to /search/... and produced “Sorry, you have been blocked” rather than results. F07 high: The primary search journey is blocked by Cloudflare |
support-core-task-successclear-system-state-and-recovery | issues | high | The search result is a generic Cloudflare block whose only recovery is to email the site owner; it does not preserve the query or offer retry/back-to-results. F08 high: Blocked search offers no in-product recovery |
be-fast-and-stablegood-core-web-vitals | issues | high | Mobile Lighthouse measured LCP 3.3s, TBT 320ms, Speed Index 13.6s, and time-to-interactive 33.6s; the trace also measured FCP/LCP 4.50s. F09 high: Load responsiveness misses the good performance range |
be-fast-and-stablevisual-stability | pass | high | Observed CLS was 0 in the mobile layout primitive and approximately 0.00008 in Lighthouse. |
be-fast-and-stableefficient-main-thread | issues | high | Lighthouse measured 320ms TBT and 33.6s time-to-interactive, despite the shorter native trace observing only 2.08ms TBT in its window. F10 medium: Third-party work blocks interactivity |
be-fast-and-stableefficient-resource-delivery | issues | high | The HAR recorded 663 requests and 4.19MB transferred, including 557 image requests and 545 HTTP 403 responses; parser-inserted jQuery/Bootstrap and four stylesheets are candidate blockers. F11 high: The listing performs hundreds of wasteful requests |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | Lighthouse estimated 529KiB unused JavaScript and 22KiB unused CSS, including 93% of Bootstrap CSS and substantial ad/analytics code. F12 medium: Large unused third-party bundles dominate the page |
be-inclusivenames-roles-labels | issues | high | The image audit found 100/100 images without alt; Lighthouse also failed image-alt and found an unlabeled upload input, while DOM probes found unlabeled search controls. F13 high: Images and form controls lack accessible names |
be-inclusivesufficient-contrast | issues | high | Lighthouse measured 3.46:1 for notice links and 4.19:1 for dark-theme tab links, below the 4.5:1 text minimum. F14 medium: Link and tab colors fail WCAG contrast |
be-inclusivestructure-and-focus | issues | high | The homepage probe found no headings and no <main>; the category control computed outline:none and box-shadow:none when focused. F15 high: The homepage lacks a heading/main structure and one menu has no focus indicator |
be-inclusivelegible-text | issues | high | The 360px screenshot shows 更新順 and シャッフル split vertically into individual characters, making navigation slow to scan. F16 medium: Mobile tab labels wrap one character per line |
be-inclusivezoom-reflow-targets-and-media | issues | high | The focus/geometry probe found 18 of 30 sampled controls below 44px in one dimension, including 17px-high utility links. F17 medium: Small touch targets undermine reflow usability |
follow-best-practicesno-console-errors | issues | high | Lighthouse failed errors-in-console with repeated CORS failures from Geniee and GMO advertising endpoints. F18 medium: Advertising code emits repeated console errors |
follow-best-practicessound-document-and-assets | issues | high | The image audit found 100 images without dimensions; screenshots show the logo broken, and the HAR contains 545 HTTP 403 responses, mostly thumbnails. F19 medium: Image assets are broken and unsized |
follow-best-practicesbrowser-platform-hygiene | issues | high | Lighthouse reported four deprecation warnings, inspector cookie issues, and five BFCache failure reasons including cache-control:no-store. F20 medium: Deprecated APIs and BFCache blockers remain |
be-discoverabletitle-and-description | pass | high | Homepage and thread pages expose descriptive titles and meta descriptions in server-rendered HTML. |
be-discoverablecrawlable-and-mobile-friendly | issues | high | Lighthouse found an <a onclick="location.reload()"> without href, and the page declares meta robots index,nofollow despite a public forum; viewport metadata is present. F21 medium: Some navigation is not crawlable and all page links are marked nofollow |
be-discoverablecanonical-and-indexing-signals | issues | high | The homepage has no canonical URL, declares index,nofollow, and /sitemap.xml returned a Cloudflare block, although robots.txt allows general search crawling. F22 medium: Homepage indexing signals are inconsistent |
be-discoverablestructured-and-shareable-metadata | issues | high | Open Graph metadata exists, but the homepage probe found no JSON-LD and the thread exposes no DiscussionForumPosting schema. F23 low: Forum threads lack structured discussion metadata |
be-private-and-securesecure-transport-and-headers | issues | high | HTTPS is used, but PHPSESSID lacks Secure and HttpOnly; seven other cookies lack Secure. CSP and nosniff are missing, and HSTS is effectively disabled with max-age=0. F24 critical: Session and analytics cookies are insecure and core security headers are absent |
be-private-and-securedata-minimisation-and-third-parties | issues | high | The tracker probe found 41 third-party origins and 12 known tracker domains; the HAR measured 99 third-party requests and 1.19MB transferred. F25 high: The page contacts an excessive tracking ecosystem |
be-private-and-securein-context-permissions-and-modern-auth | not-applicable | high | No authentication surface or browser permission request was present on the representative public forum pages. |
be-private-and-securedefensive-browser-policies | issues | high | The header probe found no CSP/frame-ancestors or X-Frame-Options, no Referrer-Policy, no Permissions-Policy, and HSTS max-age=0. F26 high: Browser-enforced defensive policies are mostly absent |
be-resilientprogressive-enhancement | pass | high | Raw server HTML contained 100% of rendered content tokens, with title and description intact; the page is not a JS shell. |
be-resilientresilient-runtime-behaviour | pass | high | Successful homepage and thread loads use ordinary links/forms and showed no cut-off overlay or fragile custom top-layer UI. |
be-resilientoffline-and-installable | not-applicable | high | This public MPA discussion forum is not presented as an installable app; no offline editing or app-like promise was identified. |
be-resilientnetwork-and-http-failure-states | issues | high | Category, settings, contact, sitemap, and an ordinary search were intermittently replaced by Cloudflare “Sorry, you have been blocked” pages. F27 high: Network/security failures replace the site with an unrecoverable generic page |
be-internationalisedlang-dir-and-logical-properties | not-applicable | high | The site is deliberately Japanese-language and Japan-locale community content with no locale switch, currency, scheduling, or cross-time-zone workflow in the audited scope. |
be-internationalisedlocale-aware-data | not-applicable | high | The site is deliberately Japanese-language and Japan-locale community content with no locale switch, currency, scheduling, or cross-time-zone workflow in the audited scope. |
be-internationalisedtime-zone-correctness | not-applicable | high | The site is deliberately Japanese-language and Japan-locale community content with no locale switch, currency, scheduling, or cross-time-zone workflow in the audited scope. |
be-trustworthyno-dark-patterns | pass | high | No forced continuity, confirmshaming, disguised action, subscription pressure, or nagging consent wall appeared in the audited public flows. |
be-trustworthyhumane-error-handling | pass | high | The visible search input uses native required validation; no premature custom invalid state appeared before interaction. |
be-trustworthytrustworthy-input-assistance | issues | high | The DOM probe found empty autocomplete values and no labels on search and upload controls. F28 low: Form controls omit useful input metadata |
be-trustworthysafe-commercial-and-account-flows | not-applicable | high | No checkout, subscription, authentication, account-management, or payment flow exists in the audited public scope. |
be-sustainableoptimised-assets | issues | high | The image audit found 99 below-fold images without lazy loading and all 100 sampled images without dimensions; the HAR recorded 557 image requests and 2.96MB transferred. F29 high: Hundreds of thumbnails are fetched eagerly without intrinsic sizing |
be-sustainableno-wasteful-work | issues | high | The HAR recorded 663 requests with 545 HTTP 403 responses, while Lighthouse reported repeated advertising CORS failures. F30 high: Failed advertising and thumbnail work consumes resources without user value |
be-sustainablethird-party-and-media-budget | issues | high | The HAR attributes 1.19MB and 99 requests to third parties; tracker evidence lists 41 third-party origins and 12 known trackers. F31 high: Third-party cost is disproportionate to a text forum |
be-agent-readystructured-agent-capabilities | not-applicable | high | No developer intent for agent-executed forum capabilities is evident; robots.txt explicitly restricts several AI crawlers, so absence of WebMCP is not penalised. |
be-agent-readyon-device-inference | not-applicable | high | No summarisation or language-model task is promised by this conventional public forum, so built-in inference is optional rather than required. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | After 10 dark-mode/tab interaction cycles, heap nodes decreased from 509,665 to 507,687 and self size decreased from 27,511,079 to 27,456,329 bytes. |
be-memory-efficientbounded-footprint | pass | high | The loaded long listing used about 27.5MB heap self-size with 3,347 DOM elements; substantial but bounded for the 21k-28k px feed and ad integrations. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | No Detached* constructor appeared in either heap summary and repeated interaction reduced total nodes/edges rather than accumulating them. |
