All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	Desktop screenshots in default and prefers-color-scheme: dark are pixel-identical white pages; the DOM reports color-scheme: normal and no CSS. F001 medium: The page ignores the user’s dark colour-scheme preference
respect-user-preferences `respects-reduced-motion`	pass	high	Under prefers-reduced-motion: reduce, matchMedia is active and document.getAnimations() returns zero animations; there is no non-essential motion to suppress.
respect-user-preferences `respects-contrast`	pass	high	The rendered error uses black text on a white browser-default background with clearly visible text and rule; no custom scrollbar or control styling interferes with forced colours.
implement-natural-interactions `view-transitions`	pass	high	Rendered screenshot, DOM, page probe, reduced-motion probe, and network evidence directly inspect the reachable surface.
implement-natural-interactions `scroll-driven-animations`	pass	high	Rendered screenshot, DOM, page probe, reduced-motion probe, and network evidence directly inspect the reachable surface.
implement-natural-interactions `physical-gestures`	pass	high	Rendered screenshot, DOM, page probe, reduced-motion probe, and network evidence directly inspect the reachable surface.
provide-guided-navigation `scroll-state-aware-chrome`	pass	high	Rendered screenshot, DOM, page probe, reduced-motion probe, and network evidence directly inspect the reachable surface.
provide-guided-navigation `anchored-positioning`	pass	high	Rendered screenshot, DOM, page probe, reduced-motion probe, and network evidence directly inspect the reachable surface.
provide-guided-navigation `directs-attention`	issues	high	The rendered 404 contains no anchors, navigation landmark, home link, search, or recovery action. F002 high: The error page offers no route back to useful content
maximize-content-reduce-noise `no-intrusive-interruptions`	pass	high	Rendered screenshot, DOM, page probe, reduced-motion probe, and network evidence directly inspect the reachable surface.
maximize-content-reduce-noise `semantic-dismissible-primitives`	pass	high	Rendered screenshot, DOM, page probe, reduced-motion probe, and network evidence directly inspect the reachable surface.
maximize-content-reduce-noise `reduced-chrome`	pass	high	Rendered screenshot, DOM, page probe, reduced-motion probe, and network evidence directly inspect the reachable surface.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	pass	high	Desktop/mobile screenshots, layout metrics, and semantic probe inspect reflow, landmarks, focusables, text, media, and controls.
adapt-to-the-form-factor `component-level-responsiveness`	pass	high	Desktop/mobile screenshots, layout metrics, and semantic probe inspect reflow, landmarks, focusables, text, media, and controls.
adapt-to-the-form-factor `input-modality-aware`	issues	high	The page-probe found zero focusable elements, so keyboard and touch users cannot recover from the 404 within the page. F003 high: There is no keyboard, touch, or pointer recovery control
support-core-task-success `clear-purpose-and-primary-action`	issues	high	The first-viewport screenshot contains only “404 Not Found” and “nginx”; there is no site identity, content, or call to action. F004 high: The public entry URL does not explain the site or expose a next action
support-core-task-success `primary-flow-completion`	issues	high	The main document returns HTTP 404. The DOM has no internal links or forms, and robots.txt and sitemap.xml also return 404, leaving no discoverable journey to exercise. F005 critical: The primary experience is unavailable at the supplied public URL
support-core-task-success `clear-system-state-and-recovery`	issues	high	The HTTP error is visible, but there is no explanation, retry, home link, search, or support route; the HAR confirms the document itself is 404. F006 high: The 404 state has no useful recovery options
be-fast-and-stable `good-core-web-vitals`	pass	high	Trace, layout, HAR, and image audit directly measure the reachable document: LCP 880 ms, CLS 0, TBT 0, 14.4 KB, no image issues or render-blocking candidates.
be-fast-and-stable `visual-stability`	pass	high	Trace, layout, HAR, and image audit directly measure the reachable document: LCP 880 ms, CLS 0, TBT 0, 14.4 KB, no image issues or render-blocking candidates.
be-fast-and-stable `efficient-main-thread`	pass	high	Trace, layout, HAR, and image audit directly measure the reachable document: LCP 880 ms, CLS 0, TBT 0, 14.4 KB, no image issues or render-blocking candidates.
be-fast-and-stable `efficient-resource-delivery`	pass	high	Trace, layout, HAR, and image audit directly measure the reachable document: LCP 880 ms, CLS 0, TBT 0, 14.4 KB, no image issues or render-blocking candidates.
be-fast-and-stable `trim-unused-and-duplicate-code`	pass	high	Trace, layout, HAR, and image audit directly measure the reachable document: LCP 880 ms, CLS 0, TBT 0, 14.4 KB, no image issues or render-blocking candidates.
be-inclusive `names-roles-labels`	pass	high	Desktop/mobile screenshots, layout metrics, and semantic probe inspect reflow, landmarks, focusables, text, media, and controls.
be-inclusive `sufficient-contrast`	pass	high	Desktop/mobile screenshots, layout metrics, and semantic probe inspect reflow, landmarks, focusables, text, media, and controls.
be-inclusive `structure-and-focus`	issues	high	The page-probe found one H1 but zero main/nav/header/footer/role landmarks and zero focusable controls. F007 medium: The error document lacks landmarks and a focusable recovery path
be-inclusive `legible-text`	pass	high	Desktop/mobile screenshots, layout metrics, and semantic probe inspect reflow, landmarks, focusables, text, media, and controls.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	At a requested 360×800 viewport, layout metrics report a 980 CSS-pixel layout viewport and scale 0.367 because meta[name=viewport] is absent. F008 high: The document omits the viewport meta tag
follow-best-practices `no-console-errors`	pass	medium	All CDP primitives loaded and evaluated the document without an uncaught runtime failure; Lighthouse stopped only on the HTTP 404 document status.
follow-best-practices `sound-document-and-assets`	issues	high	The DOM probe reports doctype: null and browser-decoded characterSet: windows-1252; the source has no charset declaration. F009 medium: The error document has no HTML doctype or declared charset
follow-best-practices `browser-platform-hygiene`	pass	high	Rendered screenshot, DOM, page probe, reduced-motion probe, and network evidence directly inspect the reachable surface.
be-discoverable `title-and-description`	issues	high	The DOM title is “404 Not Found” and meta[name=description] is absent. F010 high: The homepage has a generic error title and no meta description
be-discoverable `crawlable-and-mobile-friendly`	issues	high	The page has zero anchors and no viewport meta; robots.txt returns 404. F011 high: The response exposes no crawlable navigation or mobile viewport signal
be-discoverable `canonical-and-indexing-signals`	issues	high	The discoverability primitive fetched the root with status 404; curl confirmed robots.txt and sitemap.xml also return 404, and no canonical link is present. F012 critical: The public root and discovery endpoints return 404
be-discoverable `structured-and-shareable-metadata`	issues	high	The page-probe found zero JSON-LD blocks, zero Open Graph tags, and no canonical metadata. F013 medium: No structured or social-preview metadata describes the site
be-private-and-secure `secure-transport-and-headers`	issues	high	The headers primitive confirms HTTPS but finds no CSP, HSTS, or X-Content-Type-Options; the Cloudflare clearance cookie is Secure and HttpOnly. F014 high: Key transport and content security headers are missing
be-private-and-secure `data-minimisation-and-third-parties`	pass	high	Tracker and HAR probes report zero third-party origins and no known trackers; the secret scan reports zero findings.
be-private-and-secure `in-context-permissions-and-modern-auth`	pass	high	Headers, cookie, tracker, secret, HAR, and DOM probes directly inspect the reachable response.
be-private-and-secure `defensive-browser-policies`	issues	high	X-Frame-Options: SAMEORIGIN and Referrer-Policy: same-origin are present, but Permissions-Policy, CSP/frame-ancestors, HSTS, and nosniff are absent. F015 medium: Browser-enforced defensive policy coverage is incomplete
be-resilient `progressive-enhancement`	pass	high	Raw HTML and rendered DOM contain the same 404 heading without relying on JavaScript; discoverability reports isJsShell: false.
be-resilient `resilient-runtime-behaviour`	pass	high	Discoverability, raw HTTP recon, DOM, and screenshots show a server-rendered 404 with no functioning route or recovery path.
be-resilient `offline-and-installable`	not-applicable	high	The reachable surface is a server error page and recon exposed no app manifest or functioning application whose install/offline intent could be judged.
be-resilient `network-and-http-failure-states`	issues	high	The representative HTTP failure state is only the nginx 404 and offers no retry, fallback content, or navigation. F016 high: The network failure state is a bare server page
be-internationalised `lang-dir-and-logical-properties`	issues	high	The DOM probe reports empty html.lang and html.dir, so assistive technology and translation tools cannot identify the page language. F017 medium: The document language and direction are not declared
be-internationalised `locale-aware-data`	not-applicable	high	The only reachable content is a 404 with no dates, numbers, currencies, durations, or locale-sensitive data.
be-internationalised `time-zone-correctness`	not-applicable	high	The only reachable content contains no time or event concepts.
be-trustworthy `no-dark-patterns`	pass	high	Rendered screenshot, DOM, page probe, reduced-motion probe, and network evidence directly inspect the reachable surface.
be-trustworthy `humane-error-handling`	not-applicable	high	No form is present on the reachable page, so form validation behaviour does not apply.
be-trustworthy `trustworthy-input-assistance`	not-applicable	high	No input fields are present on the reachable page.
be-trustworthy `safe-commercial-and-account-flows`	not-applicable	high	No checkout, subscription, consent, authentication, or account flow is exposed on the reachable page.
be-sustainable `optimised-assets`	pass	high	Rendered screenshot, DOM, page probe, reduced-motion probe, and network evidence directly inspect the reachable surface.
be-sustainable `no-wasteful-work`	pass	high	Rendered screenshot, DOM, page probe, reduced-motion probe, and network evidence directly inspect the reachable surface.
be-sustainable `third-party-and-media-budget`	pass	high	Rendered screenshot, DOM, page probe, reduced-motion probe, and network evidence directly inspect the reachable surface.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	The reachable surface is only a 404 and exposes no functioning content or task capability for an agent-facing integration.
be-agent-ready `on-device-inference`	not-applicable	high	The reachable surface has no inference-appropriate feature; adding on-device AI to a server error would not improve the experience.
be-memory-efficient `no-leak-under-repeated-interaction`	not-applicable	high	The reachable 404 page has no real interaction to repeat; fabricating one would not test representative product behaviour.
be-memory-efficient `bounded-footprint`	pass	high	Single-state heap summary is proportionate for the error page (60,096 nodes, 2.48 MB self size) and lists no Detached* constructor among top populations.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	Single-state heap summary is proportionate for the error page (60,096 nodes, 2.48 MB self size) and lists no Detached* constructor among top populations.
