All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	Dark preference leaves light surfaces unchanged. F-001 medium: The interface is hard-coded to a light palette.
respect-user-preferences `respects-reduced-motion`	pass	high	getAnimations() returned zero and no auto-advance or non-essential motion was visible.
respect-user-preferences `respects-contrast`	issues	high	Several text styles fail WCAG contrast and there is no contrast-mode adaptation. F-002 high: Low-contrast text and controls fail the accessibility floor.
implement-natural-interactions `view-transitions`	issues	medium	No view-transition declarations or transition animations were found for route/state changes. F-003 low: Listing, topic and pagination navigation swaps abruptly without directional continuity.
implement-natural-interactions `scroll-driven-animations`	pass	high	No scroll-linked animation or custom animated scrollytelling exists, so no main-thread scroll animation anti-pattern was observed.
implement-natural-interactions `physical-gestures`	pass	medium	The site relies on native page scrolling and link activation; no custom pointer gesture that fights platform behaviour was observed.
provide-guided-navigation `scroll-state-aware-chrome`	issues	medium	The 139,047px topic page has static chrome and no progress/scroll-state response. F-004 medium: Very long pages provide weak position and attention cues.
provide-guided-navigation `anchored-positioning`	not-applicable	high	No tooltip, popover or anchored menu was present on the representative templates.
provide-guided-navigation `directs-attention`	issues	medium	Pagination/list-to-topic changes have no directional transition or destination highlight, and overlapping mobile tabs weaken orientation. F-004 medium: Very long pages provide weak position and attention cues.
maximize-content-reduce-noise `no-intrusive-interruptions`	pass	high	No full-screen popup, consent wall or content-obscuring interstitial appeared on load.
maximize-content-reduce-noise `semantic-dismissible-primitives`	pass	medium	No transient modal overlay was triggered in tested flows; disclosures and navigation remained ordinary document content.
maximize-content-reduce-noise `reduced-chrome`	pass	medium	The visual frame is simple and topic/list content occupies the main surface without ornamental application chrome.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	issues	high	Topic overflows by 88px and list navigation overlaps at narrow width. F-005 high: Core listing and topic components do not reliably reflow on narrow screens.
adapt-to-the-form-factor `component-level-responsiveness`	issues	high	No container-responsive component was found and reused ranking/new tabs visibly collide at 360px. F-005 high: Core listing and topic components do not reliably reflow on narrow screens.
adapt-to-the-form-factor `input-modality-aware`	issues	high	Many links remove focus outlines; pagination targets measure 34x28px. F-007 high: Keyboard focus and target sizing are inadequate, and zoom is disabled on mobile.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	Ranking, new topics, search and comment actions are visible and Japanese labels make each template purpose clear.
support-core-task-success `primary-flow-completion`	pass	medium	Users can open topics, paginate comments and complete a search without an account wall or dead end.
support-core-task-success `clear-system-state-and-recovery`	pass	high	The 404 state explains the problem and provides a prominent return-to-top action.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse LCP is 8.6s and TBT 10,680ms; performance score is 0.28. F-008 critical: Mobile loading and main-thread responsiveness are critically slow.
be-fast-and-stable `visual-stability`	pass	high	Homepage CLS was 0 and topic CLS was 0.0011, both in the good range.
be-fast-and-stable `efficient-main-thread`	issues	high	TBT is 10,680ms in Lighthouse; trace also observed a 199ms long task. F-008 critical: Mobile loading and main-thread responsiveness are critically slow.
be-fast-and-stable `efficient-resource-delivery`	issues	high	A non-deferred classic script, render-blocking CSS, uncached font and uncompressed script are present. F-009 high: Resource delivery includes blocking, uncached and largely unused work.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Estimated savings are 189KiB JS and 15KiB CSS; two large Google tag bundles appear in the Lighthouse load. F-009 high: Resource delivery includes blocking, uncached and largely unused work.
be-inclusive `names-roles-labels`	issues	high	Missing alt, unnamed links/iframes and unlabeled inputs were directly enumerated. F-006 high: Essential controls, images and page regions are not exposed cleanly to assistive technology.
be-inclusive `sufficient-contrast`	issues	high	Pink on white is measured at 2.2:1 and other grey labels at 3.94:1. F-002 high: Low-contrast text and controls fail the accessibility floor.
be-inclusive `structure-and-focus`	issues	high	No main landmark and multiple focused links have no visible outline. F-006 high: Essential controls, images and page regions are not exposed cleanly to assistive technology. F-007 high: Keyboard focus and target sizing are inadequate, and zoom is disabled on mobile.
be-inclusive `legible-text`	issues	high	Tabs overlap dates/labels and topic content exceeds the viewport, harming reading and scanability. F-005 high: Core listing and topic components do not reliably reflow on narrow screens.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	Mobile markup disables user scaling and pagination targets are only 34x28px. F-007 high: Keyboard focus and target sizing are inadequate, and zoom is disabled on mobile.
follow-best-practices `no-console-errors`	pass	high	errors-in-console passed with no captured console errors.
follow-best-practices `sound-document-and-assets`	issues	high	Doctype/charset exist, but image accessibility/responsiveness is poor and asset structure causes multiple audits to fail. F-010 medium: Long listings eagerly load poorly described, non-responsive image assets.
follow-best-practices `browser-platform-hygiene`	issues	high	Synchronous XHR and deprecated Topics API use were captured, and Inspector Issues failed. F-011 medium: Third-party integrations use deprecated and main-thread-hostile browser behaviour.
be-discoverable `title-and-description`	pass	high	Homepage and topic have descriptive titles; homepage has a substantive meta description.
be-discoverable `crawlable-and-mobile-friendly`	issues	high	Links use href and robots allows crawling, but mobile zoom is disabled and narrow content overflows. F-005 high: Core listing and topic components do not reliably reflow on narrow screens. F-007 high: Keyboard focus and target sizing are inadequate, and zoom is disabled on mobile.
be-discoverable `canonical-and-indexing-signals`	pass	high	HTTP is 200, canonical is present, robots allows public pages and advertises a current sitemap index.
be-discoverable `structured-and-shareable-metadata`	issues	medium	Open Graph/Twitter tags exist, but no JSON-LD structured entity was found for content/discussion templates. F-012 low: Topic entities lack machine-readable structured data.
be-private-and-secure `secure-transport-and-headers`	issues	high	HTTPS is used, but CSP/HSTS/nosniff are absent and two cookies are not Secure. F-013 high: The HTTPS response omits all major defensive security headers and analytics cookies are insecurely scoped.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	14 of 19 requests and 258,759 bytes are third-party; known trackers and 400-day cookies are active. F-014 medium: Tracking and third-party work dominate the small content-page transfer budget.
be-private-and-secure `in-context-permissions-and-modern-auth`	not-applicable	high	No geolocation/notification request and no authentication flow was present in scope.
be-private-and-secure `defensive-browser-policies`	issues	high	HSTS, clickjacking protection, Referrer-Policy and Permissions-Policy are all absent. F-013 high: The HTTPS response omits all major defensive security headers and analytics cookies are insecurely scoped.
be-resilient `progressive-enhancement`	pass	high	Raw HTML returned 200 with 100% content coverage; title, H1 and description survive without JavaScript.
be-resilient `resilient-runtime-behaviour`	pass	medium	Core MPA navigation and search rendered without fragile shell, cut-off overlay or async blank state.
be-resilient `offline-and-installable`	not-applicable	high	No manifest is exposed; this is a public discussion/content MPA rather than an installable application.
be-resilient `network-and-http-failure-states`	pass	medium	The invalid route has clear Japanese error copy and a working route back to the homepage.
be-internationalised `lang-dir-and-logical-properties`	issues	high	Desktop/topic variants return an empty html lang for Japanese content. F-015 medium: Some served templates omit the document language.
be-internationalised `locale-aware-data`	not-applicable	high	The scoped flows show Japanese-relative timestamps and no user-entered currency/calendar data requiring multi-locale formatting.
be-internationalised `time-zone-correctness`	not-applicable	high	No scheduling, cross-zone event or editable time concept exists in the representative journeys.
be-trustworthy `no-dark-patterns`	pass	medium	No consent wall, confirmshaming, forced subscription or disguised primary control appeared in the tested journeys.
be-trustworthy `humane-error-handling`	not-applicable	medium	Search has no invalid state and posting was not submitted to avoid publishing content to a live community.
be-trustworthy `trustworthy-input-assistance`	issues	high	Search and comment inputs lack labels and useful autocomplete metadata. F-016 medium: Search and comment inputs lack labels and useful autofill/input assistance.
be-trustworthy `safe-commercial-and-account-flows`	not-applicable	high	No checkout, subscription, account or authentication flow exists in the public anonymous journey.
be-sustainable `optimised-assets`	issues	high	97 below-fold images are not lazy, with oversized/legacy/non-responsive assets. F-010 medium: Long listings eagerly load poorly described, non-responsive image assets.
be-sustainable `no-wasteful-work`	issues	high	Heavy unused JavaScript and analytics work produces 10.68s TBT for a text-focused page. F-008 critical: Mobile loading and main-thread responsiveness are critically slow. F-017 high: Third-party JavaScript is disproportionate to the core text-listing experience.
be-sustainable `third-party-and-media-budget`	issues	high	Third parties are 78% of transfer bytes and duplicate analytics bundles dominate script cost. F-017 high: Third-party JavaScript is disproportionate to the core text-listing experience.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	Content is fully available in raw HTML, but no agent action surface or developer intent for agent tooling is evident.
be-agent-ready `on-device-inference`	not-applicable	high	No summarisation or inference feature exists, and on-device AI is not necessary to complete the core reading/search journey.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	medium	After ten bottom/top scroll cycles, heap self-size changed from 37,604,766 to 37,681,075 bytes (~0.2%) and node count fell from 562,666 to 562,204, showing no unbounded retained growth.
be-memory-efficient `bounded-footprint`	pass	medium	Topic heap is ~37.6MB despite a very long comment page; homepage uses ~3.9MB JS heap with 4,659 live DOM elements, proportionate to the rendered feed.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	medium	The valid repeated-scroll run did not increase node count and total heap remained effectively flat; no accumulating DOM population was observed.
