All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | The dark-emulated listing screenshot is byte-identical to the light desktop capture and remains white; DOM tokens include dark values but the rendered page stays light. F01 medium: Dark preference is ignored on public content pages |
respect-user-preferencesrespects-reduced-motion | issues | high | The live CSS probe found one active animation and no prefers-reduced-motion rule on the listing surface. F02 medium: Motion is not reduced for users who request it |
respect-user-preferencesrespects-contrast | issues | high | Lighthouse accessibility reported a failing color-contrast audit on the mobile listing. F03 medium: Automated contrast checks fail |
implement-natural-interactionsview-transitions | issues | high | The rendered CSS probe found no view-transition declarations across the listing SPA surface. F04 low: Route and state changes do not use View Transitions |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No parallax, scrollytelling, or scroll-linked reveal experience is part of the audited public templates. |
implement-natural-interactionsphysical-gestures | pass | high | Screenshots and DOM show native document scrolling and standard controls; no custom pointer-driven gesture surface was present. |
provide-guided-navigationscroll-state-aware-chrome | issues | high | The long mobile capture shows a 5,608px feed with no progress indication; the CSS probe found no scroll-state or scroll-timeline implementation. F05 low: Long listing chrome does not communicate scroll state |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip or edge-sensitive anchored overlay was opened or required in the representative logged-out flow. |
provide-guided-navigationdirects-attention | pass | high | Listing tabs, selected tag treatment, artwork hierarchy, and the 404 Back to Homepage action visibly direct the next step. |
maximize-content-reduce-noiseno-intrusive-interruptions | pass | high | Public listing, artwork, and profile captures expose content without a full-screen interstitial; account prompts remain inline. |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | DOM probes across listing and login found zero dialog, popover, and details elements despite menus and the privacy notice surface. F06 low: Transient UI is implemented without semantic overlay primitives |
maximize-content-reduce-noisereduced-chrome | pass | high | Screenshots show artwork grids and content occupying most of the viewport with restrained persistent chrome. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | At the requested 360x800 condition, layout metrics exposed a 1,366 CSS-pixel layout viewport scaled to 0.2635 and the screenshot shows extremely small text and controls. F07 high: Mobile renders a scaled desktop canvas instead of a mobile layout |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | high | The CSS probe found no @container rules; mobile behavior relies on a scaled, fixed-width page and viewport-wide rules. F08 medium: Reusable content grids do not respond at component level |
adapt-to-the-form-factorinput-modality-aware | issues | high | The live probe counted 193 rendered targets below 24px in at least one dimension; the first focused button computed to outline-style none. Lighthouse also failed target-size. F09 high: Many targets are too small and keyboard focus is not visible |
support-core-task-successclear-purpose-and-primary-action | pass | high | Listing heading, artwork content, search, Create an account, and Log in actions communicate purpose and next steps. |
support-core-task-successprimary-flow-completion | pass | high | A logged-out user can browse listing to artwork/profile and reach a complete login form; no avoidable dead end occurred in that representative flow. |
support-core-task-successclear-system-state-and-recovery | pass | high | Unavailable artwork produced a clear Page not found state with a Back to Homepage action. |
be-fast-and-stablegood-core-web-vitals | issues | high | Trace measured LCP 6.98s; Lighthouse lab LCP was 21.0s, TBT 751ms, and CLS 0.111. Artwork layout CLS reached 0.358. F10 high: Core Web Vitals are outside good thresholds |
be-fast-and-stablevisual-stability | issues | high | Layout observers measured CLS 0.205 on listing and 0.358 on artwork, with individual shifts up to 0.223. F11 high: Late content causes substantial layout shift |
be-fast-and-stableefficient-main-thread | issues | high | Trace found five long tasks and 168ms TBT; Lighthouse measured 751ms TBT. F12 high: Startup JavaScript blocks the main thread |
be-fast-and-stableefficient-resource-delivery | issues | high | HAR recorded 127 requests and 3.16MB transferred, including 2.84MB of script; trace LCP occurred at 6.98s. F13 high: Critical delivery is slow and script-heavy |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | HAR recorded 69 script requests and 2.84MB transferred for a public listing, with many ad-tech origins. F14 high: The page ships an excessive script payload |
be-inclusivenames-roles-labels | issues | high | Lighthouse failed image-alt, link-name, frame-title, landmark-one-main, and accessibility-tree audits; probe counted 121 unnamed links. F15 high: Controls and links lack accessible names and landmarks |
be-inclusivesufficient-contrast | issues | high | Lighthouse failed the color-contrast audit on the mobile listing. F16 medium: Some text fails WCAG contrast |
be-inclusivestructure-and-focus | issues | high | The page has no main element, 121 unnamed links, and the focused button computed outline-style none. F17 high: Focus and document structure are not robust |
be-inclusivelegible-text | issues | high | The 360x800 screenshot fits a 1,366px-wide desktop canvas into the phone viewport, reducing text and controls to a fraction of intended size. F18 high: Scaled mobile rendering makes text illegible |
be-inclusivezoom-reflow-targets-and-media | issues | high | The narrow capture is a scaled desktop layout and Lighthouse failed target-size; the probe found 193 undersized targets. F19 high: Reflow and target sizing fail on mobile |
follow-best-practicesno-console-errors | issues | high | Lighthouse recorded CORS failures and failed resource loads from Geniee and Adingo advertising endpoints. F20 medium: Advertising requests generate console errors |
follow-best-practicessound-document-and-assets | issues | high | Image audit found 17 of 24 images without dimensions, five oversized, five without srcset, and 21 in legacy formats. F21 medium: Images lack dimensions and responsive delivery |
follow-best-practicesbrowser-platform-hygiene | issues | high | Lighthouse reported deprecated Shared Storage, persistent storage, Topics, and Protected Audience use, plus BFCache and inspector-issues failures. F22 medium: Deprecated APIs and browser lifecycle blockers remain |
be-discoverabletitle-and-description | pass | high | Probe found a descriptive title and meta description on the listing; artwork also exposed a descriptive title in raw HTML. |
be-discoverablecrawlable-and-mobile-friendly | pass | high | DOM contains real href links, viewport metadata is present, and robots.txt returned 200 with targeted rather than site-wide disallow rules. |
be-discoverablecanonical-and-indexing-signals | pass | high | Listing returned 200 and exposed canonical https://www.pixiv.net/en/tags/original; robots.txt was reachable and did not block the audited paths. |
be-discoverablestructured-and-shareable-metadata | issues | high | The artwork page has Open Graph metadata, but the live probe found zero JSON-LD blocks on the public content surface. F23 medium: Rich pages omit structured entity metadata |
be-private-and-securesecure-transport-and-headers | issues | high | Header audit found no CSP or X-Content-Type-Options; cookie audit found eight cookies without Secure and all 18 with SameSite=None. F24 high: Security headers and cookie flags are incomplete |
be-private-and-securedata-minimisation-and-third-parties | issues | high | Tracker audit found 34 third-party origins and 12 known tracker domains; multiple analytics identifiers persist for 400 days. F25 high: Public browsing activates a large tracking footprint |
be-private-and-securein-context-permissions-and-modern-auth | pass | high | No permission prompt appeared on load; login inputs use username webauthn and current-password webauthn autocomplete tokens plus federated options. |
be-private-and-securedefensive-browser-policies | issues | high | Headers lacked CSP, Referrer-Policy, Permissions-Policy, and X-Content-Type-Options; HSTS and X-Frame-Options were present. F26 high: Defensive browser policies are missing |
be-resilientprogressive-enhancement | issues | high | Discoverability measured only 7% raw/rendered word coverage and classified the listing as a JS shell; artwork coverage was 14%. F27 high: Core listing content is mostly unavailable without JavaScript |
be-resilientresilient-runtime-behaviour | pass | high | Listing, artwork, profile, login, and error surfaces reached stable rendered states without clipped modal content. |
be-resilientoffline-and-installable | pass | high | Probe found a manifest URL and an active service-worker controller on the app-like listing surface. |
be-resilientnetwork-and-http-failure-states | pass | high | An unavailable artwork rendered an intentional 404 with clear recovery instead of a blank shell. |
be-internationalisedlang-dir-and-logical-properties | pass | high | The English listing and login set html lang=en and expose a visible language selector on login. |
be-internationalisedlocale-aware-data | pass | high | The /en route renders localized English labels and human-readable dates on artwork cards rather than one fixed Japanese UI. |
be-internationalisedtime-zone-correctness | not-applicable | high | The audited public art browsing and login surfaces contain no scheduling or time-zone-sensitive event flow. |
be-trustworthyno-dark-patterns | pass | high | Observed public browsing and login surfaces use explicit Create account and Log in labels without confirmshaming or disguised actions. |
be-trustworthyhumane-error-handling | pass | high | Login uses native text/password inputs and keeps alternative sign-in methods visible; the observed 404 gives neutral, actionable recovery. |
be-trustworthytrustworthy-input-assistance | pass | high | Login probe found autocomplete="username webauthn" and "current-password webauthn" on the credential fields. |
be-trustworthysafe-commercial-and-account-flows | pass | high | Account entry identifies existing-account login separately from account creation and supports federated sign-in plus WebAuthn autocomplete. |
be-sustainableoptimised-assets | issues | high | Image audit found 21 legacy-format images, five oversized images, five without srcset, and 17 without dimensions. F28 medium: Image delivery wastes bytes |
be-sustainableno-wasteful-work | issues | high | HAR recorded 69 script requests and tracker audit found 34 third-party origins, while trace recorded repeated long tasks. F29 high: Background advertising and analytics dominate work |
be-sustainablethird-party-and-media-budget | issues | high | The public listing transferred 3.16MB across 127 requests; 2.84MB was script and 34 third-party origins were contacted. F30 high: Third-party script cost is disproportionate |
be-agent-readystructured-agent-capabilities | issues | high | No structured agent capability was exposed, and non-JS discoverability covered only 7% of listing content despite clear search and browsing tasks. F31 low: Machine clients must scrape a JavaScript-heavy interface |
be-agent-readyon-device-inference | not-applicable | high | No summarisation or language-model task is necessary to complete the audited browsing and authentication journeys. |
be-memory-efficientno-leak-under-repeated-interaction | issues | low | Heap summary rose from 68.45MB and 1,463,236 nodes to 72.79MB and 1,537,506 nodes after 10 bottom/top scroll cycles, a 6.3% size increase. Separate-load noise limits confidence, but the direction warrants profiling. F32 medium: Repeated feed interaction grows the retained heap |
be-memory-efficientbounded-footprint | issues | high | Baseline heap summary contained 1,463,236 nodes and 68.45MB self size before prolonged interaction. F33 medium: The public listing has a large baseline heap footprint |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | Neither baseline nor post-interaction heap summary listed Detached constructors among retained top constructors. |
