All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	The normal and prefers-color-scheme: dark screenshots are pixel-identical; the CSS probe found no color-scheme declaration, prefers-color-scheme rule, or light-dark() usage. F1 medium: The entry surface is fixed to a light palette and does not honor the user’s dark color-scheme preference.
respect-user-preferences `respects-reduced-motion`	pass	high	Animation and CSS probes found no animations or reduced-motion-sensitive motion on the gate, so no non-essential motion persists under the preference.
respect-user-preferences `respects-contrast`	pass	high	The prefers-contrast screenshot keeps text, outlines, and both controls visible with the same high-legibility presentation.
implement-natural-interactions `view-transitions`	pass	high	The accessible gate has no in-page state swap; its two actions are ordinary cross-origin/document navigations, so there is no abrupt custom state transition to smooth.
implement-natural-interactions `scroll-driven-animations`	not-applicable	high	The accessible gate has no scroll-linked motion to implement; CSS and animation probes found none.
implement-natural-interactions `physical-gestures`	not-applicable	high	The accessible gate exposes only ordinary links and no gesture-driven interaction.
provide-guided-navigation `scroll-state-aware-chrome`	not-applicable	high	The accessible gate has no sticky or scroll-dependent chrome.
provide-guided-navigation `anchored-positioning`	not-applicable	high	The accessible gate has no tooltip, popover, or menu requiring anchored positioning.
provide-guided-navigation `directs-attention`	pass	high	Desktop and mobile screenshots use a clear question followed immediately by two labelled choices, with the primary action visually emphasized.
maximize-content-reduce-noise `no-intrusive-interruptions`	pass	high	Load screenshots show the required age gate directly, without an additional popup, ad interstitial, or content-obscuring banner layered over it.
maximize-content-reduce-noise `semantic-dismissible-primitives`	not-applicable	high	No overlay, disclosure, dialog, picker, or transient rich control appears on the accessible gate.
maximize-content-reduce-noise `reduced-chrome`	pass	high	The accessible gate devotes its layout to explanatory text and two decisions, with minimal framing and no competing navigation chrome.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	issues	high	The 360x800 screenshot shows the entire denial UI compressed into a tiny cluster; DOM evidence reports no viewport meta tag and fixed pixel sizing. F2 high: The regional-denial state does not adapt to mobile and renders at a desktop scale that is extremely difficult to read.
adapt-to-the-form-factor `component-level-responsiveness`	not-applicable	high	The accessible gate has no component reused in meaningfully different containers; its simple layout responds at the page level.
adapt-to-the-form-factor `input-modality-aware`	issues	high	The active-element/target probe measured both “I Agree” and “Reject” links at 240x40 CSS pixels. Keyboard focus is visible, but touch target height is only 40px. F3 low: The two primary touch targets are shorter than the recommended 44 CSS pixel target size.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	The first viewport states that this is an adult site, asks whether the visitor is at least 18, and exposes “I Agree” and “Reject” directly.
support-core-task-success `primary-flow-completion`	blocked	high	The audit attempted to continue through the age-confirmation journey, but the service redirected this audit location to https://special.fanza.jp/not-available-in-your-region/. Catalog, product, search, authentication, account and checkout surfaces could not be executed.
support-core-task-success `clear-system-state-and-recovery`	pass	high	After continuation is denied by region, the recovery page clearly states the condition and links to available services and the top page.
be-fast-and-stable `good-core-web-vitals`	pass	high	Lighthouse measured LCP 0.9s and CLS 0; the trace saw no long tasks and mobile layout observed CLS 0. TBT was 210ms, below the 300ms Lighthouse good threshold.
be-fast-and-stable `visual-stability`	pass	high	The mobile layout observer recorded CLS 0 with no shift entries, and Lighthouse also reports CLS 0.
be-fast-and-stable `efficient-main-thread`	issues	high	Lighthouse measured LCP at 0.9s but Time to Interactive at 8.4s and TBT at 210ms; the HAR attributes 1.04MB transferred to scripts. F4 medium: A two-action gate becomes interactive much later than its content appears because of avoidable script work.
be-fast-and-stable `efficient-resource-delivery`	issues	high	The HAR records three consecutive first-party 302 redirects before the localized age gate; Lighthouse estimates 870ms redirect savings and reports 1,650ms document-request latency savings. F5 medium: Multiple redirects and third-party script chains delay the entry document.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Lighthouse estimates 374KiB of unused JavaScript; the HAR shows 21 script requests and 920,347 third-party bytes, including six Google Tag Manager/gtag payloads totaling about 857KB. F6 high: The minimal age gate ships a disproportionate amount of unused and duplicated analytics JavaScript.
be-inclusive `names-roles-labels`	pass	high	The two meaningful controls are native anchors with clear text; Lighthouse accessibility is 0.98 and reports no accessible-name failure. Decorative/tracking images do not carry user-facing meaning.
be-inclusive `sufficient-contrast`	pass	high	Lighthouse reports no color-contrast failure, and normal/high-contrast screenshots keep all essential text and controls visibly distinct.
be-inclusive `structure-and-focus`	issues	high	The DOM probe found no headings and no main, nav, header, footer, or aside landmarks; Lighthouse specifically fails landmark-one-main. Focus on the links remains visible. F7 medium: The age gate lacks semantic page structure despite having clear visual hierarchy.
be-inclusive `legible-text`	pass	high	The entry page uses readable line lengths, spacing, and type at desktop and mobile sizes without clipping or cramped wrapping.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	At 360x800 the complete desktop layout is scaled into a tiny central cluster; DOM evidence confirms that the template omits meta viewport. F8 high: The post-confirmation denial state fails mobile reflow and presents text and controls at an unusably small scale.
follow-best-practices `no-console-errors`	pass	high	Lighthouse does not report the errors-in-console audit as failing during the captured load.
follow-best-practices `sound-document-and-assets`	pass	high	DOM evidence shows an HTML doctype and UTF-8 charset; layout records CLS 0, and the visible assets are SVG at appropriate rendered resolution.
follow-best-practices `browser-platform-hygiene`	issues	high	Lighthouse reports one deprecated API warning, logged inspector issues, and three BFCache failure reasons. F9 medium: The entry page triggers deprecated API, DevTools Issues, and back/forward cache failures.
be-discoverable `title-and-description`	pass	high	The entry gate has the descriptive title “年齢認証 - FANZA” and an English meta description explaining the adult-site restriction.
be-discoverable `crawlable-and-mobile-friendly`	issues	high	Lighthouse fails the robots-txt audit; the fetched robots.txt artifact is retained for correction. Entry links themselves use real href values and the age gate has a viewport meta tag. F10 medium: The site’s robots.txt is not valid according to Lighthouse.
be-discoverable `canonical-and-indexing-signals`	blocked	high	The audit attempted to continue through the age-confirmation journey, but the service redirected this audit location to https://special.fanza.jp/not-available-in-your-region/. Catalog, product, search, authentication, account and checkout surfaces could not be executed.
be-discoverable `structured-and-shareable-metadata`	not-applicable	high	The gate is an age check, not an article/product/event/entity intended for rich-result or social-preview representation.
be-private-and-secure `secure-transport-and-headers`	issues	high	The headers primitive found no CSP, HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, or Permissions-Policy. The cookie audit found 3 cookies without Secure and 11 using SameSite=None. F11 high: The HTTPS entry document omits baseline transport and content security headers, and several cookies are not Secure.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	The tracker scan found 15 third-party origins and known DoubleClick, Google Tag Manager, and AppNexus trackers. HAR evidence shows 25 third-party requests and 920,347 third-party bytes on a two-link gate. F12 high: Extensive tracking starts on the age gate before the user can enter the service or express a privacy choice.
be-private-and-secure `in-context-permissions-and-modern-auth`	blocked	high	The audit attempted to continue through the age-confirmation journey, but the service redirected this audit location to https://special.fanza.jp/not-available-in-your-region/. Catalog, product, search, authentication, account and checkout surfaces could not be executed.
be-private-and-secure `defensive-browser-policies`	issues	high	The header audit reports no clickjacking defense, Referrer-Policy, Permissions-Policy, CSP/frame-ancestors, or HSTS. F13 high: Browser-enforced defensive policies are absent from the entry response.
be-resilient `progressive-enhancement`	pass	high	Discoverability evidence reports 100% raw-HTML content coverage, no empty shell, and identical meaningful content without JavaScript.
be-resilient `resilient-runtime-behaviour`	pass	high	The accessible gate has no overlay/menu state or asynchronous content dependency; its ordinary links remain usable and the page renders fully from raw HTML.
be-resilient `offline-and-installable`	not-applicable	high	The entry gate is a short prerequisite document rather than an installable app; offline installation is not a proportionate requirement.
be-resilient `network-and-http-failure-states`	pass	high	The regional denial is an intentional, explanatory state with two recovery links rather than a blank shell or infinite spinner.
be-internationalised `lang-dir-and-logical-properties`	issues	high	The rendered content and description are English, while the DOM probe reports <html lang="ja">. The inspected CSS also contains no logical property usage. F14 medium: The localized English gate declares Japanese as the document language.
be-internationalised `locale-aware-data`	not-applicable	high	No dates, numbers, currency, durations, or calendar data appear on the accessible surfaces.
be-internationalised `time-zone-correctness`	not-applicable	high	No event or time-zone-sensitive data appears on the accessible surfaces.
be-trustworthy `no-dark-patterns`	pass	high	The age decision presents plainly labelled Agree and Reject options together; rejection is not hidden or confirm-shamed in the observed gate.
be-trustworthy `humane-error-handling`	not-applicable	high	No form or validation interaction exists on the accessible gate.
be-trustworthy `trustworthy-input-assistance`	not-applicable	high	No text, address, payment, sign-in, or sign-up inputs exist on the accessible gate.
be-trustworthy `safe-commercial-and-account-flows`	blocked	high	The audit attempted to continue through the age-confirmation journey, but the service redirected this audit location to https://special.fanza.jp/not-available-in-your-region/. Catalog, product, search, authentication, account and checkout surfaces could not be executed.
be-sustainable `optimised-assets`	pass	high	Visible visual assets are small SVGs at their displayed resolution; the images probe found no oversized image and no legacy raster format.
be-sustainable `no-wasteful-work`	issues	high	The HAR records 43 requests and 1,067,565 transferred bytes for a page containing two primary links; 21 requests and 1,041,721 bytes are scripts. F15 high: Background analytics work is disproportionate to the tiny gate’s user value.
be-sustainable `third-party-and-media-budget`	issues	high	Third parties account for 920,347 bytes and 25 requests; Google Tag Manager/gtag alone contributes roughly 857KB across six requests. F16 high: Third-party scripts dominate the page-weight budget.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	The accessible surface is a safety gate with no agent-facing task to expose; deeper commerce capabilities were geo-blocked and cannot be inferred.
be-agent-ready `on-device-inference`	not-applicable	high	No summarisation or language-model use case is present on the accessible gate; this emerging capability is not required here.
be-memory-efficient `no-leak-under-repeated-interaction`	not-applicable	high	The accessible gate is static and has no representative open/close, route-and-back, feed, or editor interaction to repeat without leaving the blocked flow.
be-memory-efficient `bounded-footprint`	issues	medium	A heap summary after load contains 340,289 nodes, 1,414,953 edges, and 18,817,003 bytes of self size; this aligns with the unusually heavy analytics/script payload, though deeper retained-path analysis was not possible. F17 medium: The initial heap footprint is large for a static two-action gate.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	blocked	high	The audit attempted to continue through the age-confirmation journey, but the service redirected this audit location to https://special.fanza.jp/not-available-in-your-region/. Catalog, product, search, authentication, account and checkout surfaces could not be executed.
