All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	The dark-mode screenshot is visually identical to the light capture, and the computed root color-scheme is “normal”. F01 medium: The page ignores the user’s dark color-scheme preference.
respect-user-preferences `respects-reduced-motion`	pass	medium	Direct review of the rendered landing, DOM probe, and supporting objective artifacts found the check outcome satisfied for this surface.
respect-user-preferences `respects-contrast`	issues	high	The prefers-contrast: more screenshot is unchanged, while Lighthouse independently finds a 2.45:1 text contrast failure. F02 medium: The page does not visibly adapt to increased-contrast preferences.
implement-natural-interactions `view-transitions`	issues	high	CSS inspection found no view-transition rules; the primary action performs a document navigation. F03 low: Navigation is an abrupt full-document swap with no transition treatment.
implement-natural-interactions `scroll-driven-animations`	pass	high	CSS inspection found no scroll-linked effects and trace/layout evidence found no scroll long tasks, so the page does not implement a main-thread scroll anti-pattern.
implement-natural-interactions `physical-gestures`	pass	high	DOM and CSS inspection found no gesture-driven widget, pointer-drag handler, or custom overscroll behavior that fights native interaction.
provide-guided-navigation `scroll-state-aware-chrome`	pass	high	The short landing page has no sticky/affixed chrome requiring scroll-state adaptation and no obstructive scroll behavior was observed.
provide-guided-navigation `anchored-positioning`	pass	high	The rendered landing contains no tooltip, popover, or menu overlay requiring anchored positioning.
provide-guided-navigation `directs-attention`	pass	high	The central red start control and two clearly underlined help links provide a visible navigation hierarchy on the desktop landing.
maximize-content-reduce-noise `no-intrusive-interruptions`	pass	high	Load screenshots and DOM inspection show no modal, interstitial, consent wall, or content-obscuring banner.
maximize-content-reduce-noise `semantic-dismissible-primitives`	pass	high	DOM inspection found no transient overlay or rich control implemented with an ad-hoc div.
maximize-content-reduce-noise `reduced-chrome`	issues	high	At 360×800 the 980 CSS-pixel desktop canvas is scaled down to 0.367 and most of the viewport below the 320px content column is empty. F04 low: Fixed decorative framing dominates the layout and leaves substantial unused space on narrow screens.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	issues	high	The 360×800 capture renders a 980px layout scaled to 36.7%; layout evidence reports no viewport meta on the desktop variant, and Lighthouse finds user-scalable=no on the mobile variant. F05 high: The landing page does not genuinely adapt to a narrow viewport.
adapt-to-the-form-factor `component-level-responsiveness`	issues	high	Rendered CSS inspection found no container queries; narrow evidence shows the desktop composition merely scaled down. F06 medium: Components rely on legacy page-level variants rather than adapting to their container.
adapt-to-the-form-factor `input-modality-aware`	issues	high	The focus/target probe measured footer links at only 14 CSS px high and a navigation link at 24px, below common 24/44px target guidance. F07 medium: Several interactive targets are too small for comfortable touch use.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	The first viewport names Mogg, describes it as a cooking game, and gives the start action visual prominence.
support-core-task-success `primary-flow-completion`	issues	high	Navigating directly to /my/index returns to the same /session/index login landing with no form or next step. F08 critical: The primary “start Mogg” action does not advance the unauthenticated user.
support-core-task-success `clear-system-state-and-recovery`	issues	high	After /my/index loops back, the page remains visually unchanged and provides no error, retry, or explanation. F09 high: The failed primary action gives no visible status or recovery path.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse measured FCP 5.7s and LCP 6.5s (performance 0.62); the independent trace measured LCP 4.61s. F10 high: The landing page loads well outside the good LCP range.
be-fast-and-stable `visual-stability`	pass	high	Layout observer and Lighthouse both measured CLS 0 with no recorded shifts.
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 records four document redirects, including an HTTPS→HTTP→HTTPS hop, five parser-blocking stylesheets, and classic scripts without async/defer; Lighthouse reports a 2.97s critical chain. F11 high: A long redirect and render-blocking chain delays the first content.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	The page transfers a 242,686-byte common stylesheet and jQuery 1.7 (33,915 bytes) for a mostly static 320px landing page. F12 medium: Legacy CSS and JavaScript dominate a simple landing page.
be-inclusive `names-roles-labels`	issues	high	The images audit finds five missing alt attributes; the focus probe shows the primary CTA and logo links have empty accessible text. F13 high: Meaningful images and image links lack accessible alternatives.
be-inclusive `sufficient-contrast`	issues	high	Lighthouse measured #ff6633 on #def2cc at 2.45:1, below the 4.5:1 minimum for 16px normal text. F14 medium: Orange instructional text fails WCAG contrast.
be-inclusive `structure-and-focus`	issues	high	The DOM probe found zero h1–h6 elements and only header/footer landmarks; Lighthouse flags the missing main landmark. F15 medium: The document has no heading hierarchy or main landmark.
be-inclusive `legible-text`	issues	high	The 980px desktop layout is scaled to 36.7% in the 360px capture, shrinking instructional and footer text to a few device pixels. F16 high: Text becomes too small to read comfortably on narrow screens.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	Lighthouse finds viewport content with user-scalable=no/maximum-scale=1, while the alternate desktop response omits viewport metadata. F17 high: The mobile variant prevents user zoom.
follow-best-practices `no-console-errors`	pass	high	Lighthouse best-practices evidence recorded no console-error audit failure during load.
follow-best-practices `sound-document-and-assets`	issues	high	Seven of 11 images lack complete width/height, five lack responsive sources, and all 11 are GIFs. F18 medium: Image assets omit dimensions and use legacy delivery patterns.
follow-best-practices `browser-platform-hygiene`	issues	high	HAR records common_swf_disable.js, swf2.js, swine2.min.js, and jquery-1.7.min.js as parser-inserted scripts. F19 medium: The page ships obsolete SWF-era code and jQuery 1.7.
be-discoverable `title-and-description`	issues	high	The probe reports title “ﾛｸﾞｲﾝ \| mogg” and description=null; Lighthouse fails meta-description. F20 medium: The page has no meta description and its title is minimally descriptive.
be-discoverable `crawlable-and-mobile-friendly`	issues	high	robots.txt returns 404, the desktop response lacks viewport metadata, and Lighthouse finds a javascript:void(0) link. F21 medium: Crawler and mobile signals are incomplete.
be-discoverable `canonical-and-indexing-signals`	issues	high	The page has no canonical URL; robots.txt and sitemap.xml both return 404 while the page declares index,follow. F22 medium: Indexing signals are missing or inconsistent.
be-discoverable `structured-and-shareable-metadata`	issues	high	The probe found no JSON-LD and no Open Graph properties. F23 low: The public game landing page has no structured or social-share metadata.
be-private-and-secure `secure-transport-and-headers`	issues	high	CSP, HSTS and X-Content-Type-Options are missing; both first-party cookies lack Secure and use SameSite=None. F24 high: Transport defenses and cookie attributes are incomplete.
be-private-and-secure `data-minimisation-and-third-parties`	pass	high	HAR/trackers found three asset origins, 52,752 third-party bytes, no known trackers, and no exposed secrets; no data-entry form is present.
be-private-and-secure `in-context-permissions-and-modern-auth`	issues	high	The primary /my/index route returns to the same login landing with no authentication form, passkey option, explanation, or recovery. F25 high: The only visible authentication entry fails before exposing a usable sign-in method.
be-private-and-secure `defensive-browser-policies`	issues	high	Header inspection finds no clickjacking protection, Referrer-Policy, Permissions-Policy, HSTS, or CSP frame-ancestors. F26 high: Browser-enforced defensive policies are absent.
be-resilient `progressive-enhancement`	issues	high	The discoverability raw fetch failed and the JavaScript-disabled crawler screenshot is a CloudFront 403, while the browser-rendered view succeeds. F27 high: A non-browser crawler is blocked before core content can be retrieved.
be-resilient `resilient-runtime-behaviour`	pass	high	The static landing has no overlay/async widget to cut off; its rendered state remains stable during load.
be-resilient `offline-and-installable`	issues	high	The DOM probe finds no web app manifest; no service-worker-backed fallback is exposed by the page. F28 medium: This game surface has no installability or offline fallback metadata.
be-resilient `network-and-http-failure-states`	pass	high	A representative unknown route returns HTTP 404 with an explanatory Japanese error page, navigation options, and a visible sorry illustration.
be-internationalised `lang-dir-and-logical-properties`	not-applicable	high	This Japanese-only game landing targets a single locale; rendered lang=ja is correct and no alternate writing-mode scope is declared.
be-internationalised `locale-aware-data`	not-applicable	high	No dates, currencies, durations, or other locale-sensitive data appear on the audited public landing surface.
be-internationalised `time-zone-correctness`	not-applicable	high	No time or event data appears on the audited public landing surface.
be-trustworthy `no-dark-patterns`	pass	high	Load and flow evidence shows no consent wall, confirmshaming, disguised advertisement, forced continuity, or preselected purchase.
be-trustworthy `humane-error-handling`	not-applicable	high	No user-editable form is present on the audited public landing.
be-trustworthy `trustworthy-input-assistance`	not-applicable	high	No user-editable input is present on the audited public landing.
be-trustworthy `safe-commercial-and-account-flows`	not-applicable	high	No checkout, subscription, consent, or account-management controls are reachable on the audited public landing.
be-sustainable `optimised-assets`	issues	high	All 11 images are GIF; five lack srcset and seven lack complete dimensions. F29 medium: Decorative assets are delivered only as legacy GIFs without responsive selection.
be-sustainable `no-wasteful-work`	pass	high	Trace reports no long tasks and HAR totals only 29 requests; no background polling or autoplay media was observed.
be-sustainable `third-party-and-media-budget`	pass	high	Third-party transfer is 52,752 bytes, no trackers or media autoplay were detected, and the landing ships no audio/video.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	No agent-facing capability is indicated for this consumer game landing; this emerging contextual check does not apply.
be-agent-ready `on-device-inference`	not-applicable	high	No summarisation or language-model task is present on this landing surface.
be-memory-efficient `no-leak-under-repeated-interaction`	not-applicable	high	The unauthenticated landing has no representative in-page interaction to repeat; its primary link performs a navigation loop.
be-memory-efficient `bounded-footprint`	pass	high	The heap summary is proportionate for the static page: 47,030 nodes in the V8 snapshot graph and 2.15 MB total self size.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	The single-state heap constructor summary contains no Detached* population and the page has no repeated in-page state lifecycle.
