Coverage complete
Atomic audit completed. The origin returned HTTP 200 with a zero-byte body, so the only representative public route is a blank synthesized document.
All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | The dark-mode screenshot remains a white blank surface; DOM evidence contains no color-scheme declaration or CSS. F001 medium: The page does not adapt to dark color preference |
respect-user-preferencesrespects-reduced-motion | not-applicable | high | No authored animation or transition exists to reduce; the emulated reduced-motion probe found zero animations. |
respect-user-preferencesrespects-contrast | not-applicable | high | No text, control, image, or authored color exists on which a contrast preference could operate. |
implement-natural-interactionsview-transitions | not-applicable | high | There is no route, state change, link, or control to transition. |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | The empty document has no scroll-driven content or animation. |
implement-natural-interactionsphysical-gestures | pass | high | DOM and layout probes show no custom gesture handlers, overlays, scroll traps, or competing interaction; native browser interaction remains unobstructed. |
provide-guided-navigationscroll-state-aware-chrome | not-applicable | high | There is no navigation chrome or scrollable content. |
provide-guided-navigationanchored-positioning | not-applicable | high | There is no tooltip, popover, menu, or anchored UI. |
provide-guided-navigationdirects-attention | issues | high | The rendered document has no text, links, headings, landmarks, or controls, so users cannot orient or proceed. F002 medium: No navigation or meaningful attention path exists |
maximize-content-reduce-noiseno-intrusive-interruptions | pass | high | Desktop and mobile screenshots and DOM inspection show no interstitial, popup, notification prompt, or overlay. |
maximize-content-reduce-noisesemantic-dismissible-primitives | not-applicable | high | There is no overlay, disclosure, picker, dialog, or popover to implement. |
maximize-content-reduce-noisereduced-chrome | issues | high | Both browser and crawler captures are wholly blank; the server sends zero body bytes. This is not content-first minimalism because no content survives. F003 medium: Content has been reduced to nothing |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | At a 360x800 emulation, layout reports hasViewportMeta=false and a 980 CSS-pixel layout viewport scaled to 0.367. F004 medium: The document omits the mobile viewport contract |
adapt-to-the-form-factorcomponent-level-responsiveness | pass | high | The document has no authored components; the single empty body itself introduces no fixed-width component overflow. |
adapt-to-the-form-factorinput-modality-aware | not-applicable | high | There are no interactive targets to inspect with keyboard, pointer, touch, or hover. |
support-core-task-successclear-purpose-and-primary-action | issues | high | HTTP 200 returns Content-Length: 0; rendered DOM body is empty and the screenshot is blank. F005 critical: The page has no perceivable purpose or primary action |
support-core-task-successprimary-flow-completion | issues | high | The DOM has zero links, controls, and forms, leaving no user flow to exercise. F006 critical: No primary journey can begin or complete |
support-core-task-successclear-system-state-and-recovery | issues | high | The server returns a successful 200 with an empty body rather than explaining unavailable content or offering retry/navigation. F007 medium: The blank response offers no status or recovery |
be-fast-and-stablegood-core-web-vitals | issues | high | The trace records no FCP and no LCP; Lighthouse aborts with NO_FCP. A fast blank response is not successful rendering. F008 high: The page never paints content |
be-fast-and-stablevisual-stability | pass | high | Layout observation reports CLS 0 with no shifts during load. |
be-fast-and-stableefficient-main-thread | pass | high | Trace summary reports zero long tasks and 0 ms total blocking time. |
be-fast-and-stableefficient-resource-delivery | pass | high | HAR summary records only 2 requests and 227 transferred bytes, with no render-blocking candidates or cache/redirect errors. |
be-fast-and-stabletrim-unused-and-duplicate-code | pass | high | DOM reports zero scripts and stylesheets; HAR contains no JavaScript or CSS to duplicate or leave unused. |
be-inclusivenames-roles-labels | issues | high | Rendered HTML is only empty html/head/body; there are no headings, landmarks, links, controls, names, roles, or labels. F009 medium: No semantic content or accessible interface is exposed |
be-inclusivesufficient-contrast | not-applicable | high | No foreground text or control exists against which to calculate a contrast ratio. |
be-inclusivestructure-and-focus | issues | high | DOM evidence shows zero body children; keyboard and assistive-technology users receive no structure to navigate. F010 medium: The document has no landmarks, headings, or focus path |
be-inclusivelegible-text | issues | high | Rendered and raw text character counts are both zero, confirmed by blank screenshots. F011 medium: There is no text to read |
be-inclusivezoom-reflow-targets-and-media | issues | high | The mobile probe reports no viewport meta and a default 980 CSS-pixel viewport; no targets or media exist to offer a comparable experience. F012 medium: Mobile and zoom readiness cannot meet the baseline without viewport metadata |
follow-best-practicesno-console-errors | pass | high | The empty document loads without authored scripts; DOM and trace inspection found no runtime script execution capable of emitting application errors. |
follow-best-practicessound-document-and-assets | issues | high | The origin serves Content-Type: application/octet-stream with Content-Length: 0; browser synthesizes empty html/head/body with no doctype or charset metadata. F013 high: The response is not a sound HTML document |
follow-best-practicesbrowser-platform-hygiene | issues | high | Raw headers identify the public document as application/octet-stream rather than text/html, preventing a trustworthy authored-document contract. F014 medium: The main resource uses the wrong media type |
be-discoverabletitle-and-description | issues | high | Discoverability and DOM evidence show an empty title and no meta description. F015 medium: Search and browser surfaces have no title or description |
be-discoverablecrawlable-and-mobile-friendly | issues | high | The raw response is zero bytes, renderedEmpty=true, and there is no viewport meta or crawlable link. F016 high: Crawlers and mobile users receive no content |
be-discoverablecanonical-and-indexing-signals | issues | high | There is no canonical link; /sitemap.xml returns an 8-byte non-sitemap response, while the empty page still returns 200. F017 medium: Indexing signals are incomplete |
be-discoverablestructured-and-shareable-metadata | issues | high | The empty head has no JSON-LD, Open Graph, or social preview metadata. F018 low: No structured or social metadata is present |
be-private-and-securesecure-transport-and-headers | issues | high | HTTPS and nosniff are present, but HSTS is max-age=1 and CSP is absent; raw headers also omit Referrer-Policy. F019 medium: Transport protection is underconfigured |
be-private-and-securedata-minimisation-and-third-parties | pass | high | Tracker, cookie, secret, and HAR probes found zero third-party origins, zero cookies, zero trackers, and zero exposed secret patterns. |
be-private-and-securein-context-permissions-and-modern-auth | not-applicable | high | The page requests no permission and exposes no sign-in or account flow. |
be-private-and-securedefensive-browser-policies | issues | high | Raw headers contain no CSP/frame-ancestors, X-Frame-Options, Permissions-Policy, or Referrer-Policy. F020 medium: Defensive browser policies are missing |
be-resilientprogressive-enhancement | issues | high | The server HTML is zero bytes and both JS-enabled and no-JS screenshots are blank. F021 critical: No core content exists at the network or DOM layer |
be-resilientresilient-runtime-behaviour | not-applicable | high | No application runtime, asynchronous UI, overlay, or stateful component exists to exercise. |
be-resilientoffline-and-installable | not-applicable | high | The blank public document exposes no application capability or install intent; installability is not meaningful until content is restored. |
be-resilientnetwork-and-http-failure-states | issues | high | The main document is empty but responds 200, with no error, retry, stale content, or recovery state. F022 medium: The origin masks a failed experience as HTTP 200 |
be-internationalisedlang-dir-and-logical-properties | issues | high | DOM evidence reports lang=null and dir is absent, leaving pronunciation and bidi defaults unspecified. F023 low: The document language is undeclared |
be-internationalisedlocale-aware-data | not-applicable | high | No dates, numbers, currencies, forms, or locale-sensitive data exist. |
be-internationalisedtime-zone-correctness | not-applicable | high | No date, time, event, recurrence, or scheduling data exists. |
be-trustworthyno-dark-patterns | pass | high | Visual and DOM inspection found no consent, account, payment, subscription, or persuasive controls that could implement a dark pattern. |
be-trustworthyhumane-error-handling | issues | high | A user sees a blank screen with no explanation, progress, retry, contact route, or navigation. F024 high: The outage-like blank state is silent |
be-trustworthytrustworthy-input-assistance | not-applicable | high | There are no inputs or forms. |
be-trustworthysafe-commercial-and-account-flows | not-applicable | high | There is no account, payment, checkout, pricing, subscription, or cancellation flow. |
be-sustainableoptimised-assets | pass | high | Image and HAR probes found no images, fonts, scripts, styles, or media assets wasting transfer bytes. |
be-sustainableno-wasteful-work | pass | high | Trace reports zero long tasks and the document loads no application scripts or background work. |
be-sustainablethird-party-and-media-budget | pass | high | HAR and tracker probes show zero third-party requests and no media; total transfer is 227 bytes. |
be-agent-readystructured-agent-capabilities | not-applicable | high | No application capability or user task is exposed for an agent; this contextual check does not apply to the current blank response. |
be-agent-readyon-device-inference | not-applicable | high | No inference or summarisation feature exists and the site states no such intent. |
be-memory-efficientno-leak-under-repeated-interaction | not-applicable | high | The page has no representative interaction, route, modal, feed, or state change to repeat; a synthetic repetition would not test real behavior. |
be-memory-efficientbounded-footprint | pass | high | Single-state heap summary is small (741,336 self-size bytes) and DOM probe has only 3 elements with zero body children. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | The page has no authored scripts or interactions, only 3 live DOM elements, and heap summary shows no Detached* constructor population among notable constructors. |
