All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	Light and dark captures are byte-identical (254,136 bytes), and the dark capture retains white/light-grey surfaces. F01 medium: The site ignores the user’s dark colour-scheme preference.
respect-user-preferences `respects-reduced-motion`	pass	high	Reduced-motion emulation was active; no running animations were found and only a hidden modal carried a 0.3s transition.
respect-user-preferences `respects-contrast`	pass	high	Forced-colors capture retained readable high-contrast text, controls, borders and content.
implement-natural-interactions `view-transitions`	issues	high	Representative landing, listing, article and registration navigations expose no authored view-transition CSS or route transition; page probe found no transition rules. F02 low: Navigation swaps are abrupt rather than continuity-preserving.
implement-natural-interactions `scroll-driven-animations`	not-applicable	high	No parallax, scrollytelling, scroll reveal or other scroll-linked animation exists on the representative pages, so there is no scroll-linked implementation to assess.
implement-natural-interactions `physical-gestures`	not-applicable	high	No swipe, pull, drag, carousel or other gesture-driven control exists on the audited public surfaces.
provide-guided-navigation `scroll-state-aware-chrome`	issues	high	The 2,882px landing page uses static chrome and the CSS probe found no scroll-state query or progress treatment. F03 low: Long pages provide no scroll-state-aware orientation aid.
provide-guided-navigation `anchored-positioning`	not-applicable	high	No visible tooltip, popover or anchored menu was present on the audited public states.
provide-guided-navigation `directs-attention`	issues	high	The long landing and catalogue screens use abrupt section/page changes with no current-location cue, transition, or post-navigation highlight. F04 low: Navigation does not visibly guide attention between dense sections.
maximize-content-reduce-noise `no-intrusive-interruptions`	pass	high	No load-time modal, consent wall or full-viewport interruption obscured the entry page.
maximize-content-reduce-noise `semantic-dismissible-primitives`	not-applicable	high	No user-visible transient overlay, modal flow or disclosure was present in the exercised states.
maximize-content-reduce-noise `reduced-chrome`	issues	high	The article first viewport is dominated by stacked game ads, anniversary promotion, AndApp transfer panel and cross-device promotion; article text is not visible in the captured viewport. F05 high: Promotional chrome overwhelms the news article content.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	issues	high	At 390px, the catalogue and article render multi-column desktop compositions with tiny text and controls, unlike the reflowed landing page. F06 high: Secondary templates shrink a desktop layout instead of reflowing for mobile.
adapt-to-the-form-factor `component-level-responsiveness`	issues	high	Stylesheet inspection found no @container rules; cards and promotional modules remain desktop-dense on narrow secondary templates. F07 medium: Reusable components do not adapt at component level.
adapt-to-the-form-factor `input-modality-aware`	issues	high	The interaction probe found 32 of 52 visible interactive elements under 44px in at least one dimension; footer links are only 15px high. F08 high: Many interactive targets are too small for touch.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	The first viewport clearly identifies Mobage and provides registration, login, new games, rankings and genre actions.
support-core-task-success `primary-flow-completion`	issues	high	The rendered landing-page probe found ten named new-game cards with an empty href, making the discovery path dependent on script handlers and unavailable to crawlers or standard link actions. F09 high: Several prominent game cards are not real links.
support-core-task-success `clear-system-state-and-recovery`	issues	high	The deliberately invalid URL rendered the full game portal/article-style promotional page with no 404 explanation, retry, search, or route recovery message. F10 high: Unknown URLs silently show unrelated portal content instead of a recovery state.
be-fast-and-stable `good-core-web-vitals`	issues	high	Trace measured FCP/LCP at 4.42s; Lighthouse measured FCP 4.0s and LCP 4.6s (performance 0.73). F11 high: Initial content is slow on the tested mobile load.
be-fast-and-stable `visual-stability`	pass	high	Layout observer measured CLS 0.0000375 with image dimensions present on all audited img elements.
be-fast-and-stable `efficient-main-thread`	pass	high	Trace and layout observers recorded zero long tasks and 0ms total blocking time.
be-fast-and-stable `efficient-resource-delivery`	issues	high	HAR recorded two redirects and five render-blocking candidates; Lighthouse estimates 1.49s redirect, 1.2s render-blocking and 1.1MB cache-lifetime savings. F12 high: Redirects, blocking resources and weak cache/font delivery delay content.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Lighthouse estimates 35KiB unused CSS and 42KiB unused JavaScript on a simple portal page. F13 medium: The landing page ships avoidable unused CSS and JavaScript.
be-inclusive `names-roles-labels`	issues	high	Image audit found 44 of 45 images without alt text; page probe also found an unnamed button and an unlabelled visible textarea. F14 high: Important images and controls lack accessible alternatives.
be-inclusive `sufficient-contrast`	issues	high	Lighthouse measured 2.86:1 for 11px blue footer links on #d0d0d0, below the required 4.5:1. F15 high: Footer links fail minimum text contrast.
be-inclusive `structure-and-focus`	issues	high	The interaction probe found zero main and zero navigation landmarks; Lighthouse failed landmark-one-main. Keyboard outline was visible, but structure remains weak. F16 medium: The page lacks main and navigation landmarks.
be-inclusive `legible-text`	issues	high	At 390px, listing and article templates retain dense desktop columns and tiny card/caption text that is difficult to read. F17 high: Text becomes uncomfortably small on secondary mobile templates.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	Viewport is width=device-width, maximum-scale=1.0, user-scalable=no; Lighthouse failed meta-viewport and the target probe found 32 under 44px. F18 high: The viewport disables pinch zoom and many targets are undersized.
follow-best-practices `no-console-errors`	pass	high	Lighthouse best-practices scored 1.0 and its console-errors audit passed.
follow-best-practices `sound-document-and-assets`	pass	high	DOM reports HTML doctype, UTF-8, viewport metadata and all images with explicit dimensions; Lighthouse best-practices scored 1.0.
follow-best-practices `browser-platform-hygiene`	pass	high	Lighthouse best-practices scored 1.0 with no detected deprecated API, prompt-on-load or vulnerable-library failure.
be-discoverable `title-and-description`	pass	high	Rendered HTML includes title “モバゲー” and a descriptive Japanese meta description.
be-discoverable `crawlable-and-mobile-friendly`	issues	high	Lighthouse failed crawlable-anchors; the DOM probe found multiple visible game cards with empty href values, and viewport disables scaling. F19 high: Prominent links are not crawlable and scaling is disabled.
be-discoverable `canonical-and-indexing-signals`	issues	high	The public landing page has no canonical link; /sitemap.xml returns a normal HTML marketing page rather than an XML sitemap. F20 medium: Canonical and sitemap signals are unreliable.
be-discoverable `structured-and-shareable-metadata`	issues	high	The page has no JSON-LD, og:description is empty, and no canonical URL is supplied despite representing a public game portal. F21 medium: Entity and social-preview metadata is incomplete.
be-private-and-secure `secure-transport-and-headers`	issues	high	HTTPS is used, but CSP, HSTS, nosniff, frame protection, Referrer-Policy and Permissions-Policy are absent. All three cookies lack Secure and use SameSite=None. F22 critical: Security headers and cookie protections are missing.
be-private-and-secure `data-minimisation-and-third-parties`	pass	high	No known external tracker domains or exposed secrets were detected; network origins were Mobage-controlled subdomains.
be-private-and-secure `in-context-permissions-and-modern-auth`	issues	high	The public registration entry offers only registration and login links; page/source probes found no WebAuthn/passkey capability. No permission prompt fired on load. F23 medium: The account journey exposes no phishing-resistant sign-in option.
be-private-and-secure `defensive-browser-policies`	issues	high	Header evidence found no HSTS, CSP/frame-ancestors or X-Frame-Options, Referrer-Policy, Permissions-Policy or nosniff. F24 high: Browser-enforced defensive policies are absent.
be-resilient `progressive-enhancement`	pass	high	Raw HTML was a substantive 25,665-byte document with title, h1 and description; 52% rendered-word coverage and no empty SPA shell.
be-resilient `resilient-runtime-behaviour`	pass	high	Representative public pages rendered complete content without cut-off overlays, infinite loading or uncaught runtime errors.
be-resilient `offline-and-installable`	not-applicable	high	This public game directory hands off to intrinsically online services and does not present itself as an installable app; offline/installability is not required for the audited portal.
be-resilient `network-and-http-failure-states`	issues	high	A deliberately unknown path rendered unrelated portal content with no error status/message or recovery action visible. F25 high: Route failure has no explicit recovery state.
be-internationalised `lang-dir-and-logical-properties`	not-applicable	high	The site is deliberately Japanese-only (lang=ja) and no alternate-language or bidi surface is offered; broader translation layout was judged out of scope.
be-internationalised `locale-aware-data`	not-applicable	high	No dates, currencies, locale-switching or other locale-sensitive data appeared in the representative public task surfaces.
be-internationalised `time-zone-correctness`	not-applicable	high	No event scheduling, stored times, recurring intervals or cross-time-zone flow appeared in scope.
be-trustworthy `no-dark-patterns`	pass	high	No consent nag, confirmshaming, forced continuity or disguised control appeared on the audited public and registration-entry surfaces.
be-trustworthy `humane-error-handling`	not-applicable	high	The public registration entry exposes no editable form fields; submitting account credentials was outside this unauthenticated audit.
be-trustworthy `trustworthy-input-assistance`	not-applicable	high	No visible address, payment, sign-in or sign-up input fields were exposed on the audited public pages.
be-trustworthy `safe-commercial-and-account-flows`	not-applicable	high	No checkout, subscription, cancellation or authenticated account-management flow was available without creating or using an account.
be-sustainable `optimised-assets`	issues	high	Image audit found 39 legacy PNG/GIF assets, 16 below-fold images without lazy loading and no modern-format images; Lighthouse estimates 573KiB image savings. F26 high: Image delivery is substantially unoptimised.
be-sustainable `no-wasteful-work`	pass	high	Trace observed no long tasks or continuing animation work; network capture found one XHR/fetch and no known analytics tracker.
be-sustainable `third-party-and-media-budget`	issues	high	HAR recorded 1,197,467 transferred bytes, including 1,038,457 image bytes; four legacy sprites alone total about 670KiB. F27 medium: Decorative image sprites dominate a 1.2MB landing-page transfer.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	No developer intent for agent-operated transactions or tools is declared; this emerging capability is optional for the public game directory.
be-agent-ready `on-device-inference`	not-applicable	high	No summarisation, generation or other inference task exists where an on-device model would improve the audited core journey.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	high	After ten full-page scroll cycles, heap changed from 5,020,189 to 5,045,313 bytes (+0.5%) and 89,392 to 89,497 nodes (+0.12%), with stable closure count.
be-memory-efficient `bounded-footprint`	pass	high	Heap summary was about 5.0MB and 89k nodes, proportionate to the image-heavy static portal, with no dominating application-object population.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	Repeated interaction left closure count unchanged at 2,856 and application constructors stable; summary showed no growing Detached* population.
