All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | Dark-media screenshot and computed-style probe show colorScheme "normal", transparent body, and black text; no dark scheme is declared. F002 medium: Dark-mode preference is not declared |
respect-user-preferencesrespects-reduced-motion | pass | high | The reduced-motion probe matched the requested preference and found zero active animations. |
respect-user-preferencesrespects-contrast | not-applicable | high | No text or controls exist whose visibility under forced colors can be judged; the blank state is reported under core task success instead. |
implement-natural-interactionsview-transitions | pass | high | No route or state swap exists, so the inspected page performs no abrupt or jarring transition. |
implement-natural-interactionsscroll-driven-animations | pass | high | No scroll-linked animation or JavaScript scroll handler exists; the page does not use the main-thread anti-pattern. |
implement-natural-interactionsphysical-gestures | pass | high | No custom pointer handler, overscroll override, or gesture implementation fights platform behavior. |
provide-guided-navigationscroll-state-aware-chrome | pass | high | No static or JavaScript-driven navigation chrome obscures or misrepresents scroll position. |
provide-guided-navigationanchored-positioning | pass | high | No manually positioned tooltip, menu, or popover can drift from an anchor. |
provide-guided-navigationdirects-attention | pass | high | No navigation action moves focus or context without an attention cue. |
maximize-content-reduce-noiseno-intrusive-interruptions | pass | high | Load screenshots and DOM show no overlay, banner, or interstitial. |
maximize-content-reduce-noisesemantic-dismissible-primitives | not-applicable | high | No overlays or rich controls exist. |
maximize-content-reduce-noisereduced-chrome | pass | high | The rendered viewport contains no non-content chrome or borders. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | At requested 360x800, the layout primitive reports no viewport meta and a 980 CSS-pixel layout viewport scaled to 0.367. F003 high: The mobile viewport is not configured |
adapt-to-the-form-factorcomponent-level-responsiveness | not-applicable | high | No authored component exists in any container. |
adapt-to-the-form-factorinput-modality-aware | not-applicable | high | No interactive target exists for touch, hover, or keyboard testing. |
support-core-task-successclear-purpose-and-primary-action | issues | high | Rendered DOM contains zero text characters, headings, controls, or landmarks; the desktop screenshot is blank. F001 critical: The homepage is completely blank |
support-core-task-successprimary-flow-completion | issues | high | There is no action or flow to complete: zero links, controls, and forms are present. F001 critical: The homepage is completely blank |
support-core-task-successclear-system-state-and-recovery | issues | high | The homepage is blank and a nonexistent route returns HTTP 200 with "empty OK", providing neither state explanation nor recovery action. F004 high: Error and recovery states are misleading |
be-fast-and-stablegood-core-web-vitals | issues | high | Lighthouse aborts with NO_FCP because the page never paints content; the trace also records null FCP and LCP. F005 critical: The page never paints content |
be-fast-and-stablevisual-stability | pass | high | Layout observer recorded CLS 0 with no shifts. |
be-fast-and-stableefficient-main-thread | pass | high | Trace reports zero long tasks and 0 ms total blocking time; there are no authored scripts. |
be-fast-and-stableefficient-resource-delivery | pass | high | HAR contains only two tiny first-party requests, 234 transferred bytes, no render-blocking candidates, redirects, or HTTP errors. |
be-fast-and-stabletrim-unused-and-duplicate-code | pass | high | The page ships no JavaScript or CSS and no third-party code. |
be-inclusivenames-roles-labels | not-applicable | high | No controls, forms, images, canvas, or expressive content exists to name or label. |
be-inclusivesufficient-contrast | not-applicable | high | No rendered text or essential UI exists for a contrast ratio test. |
be-inclusivestructure-and-focus | issues | high | DOM probe reports zero headings and zero landmarks, leaving no semantic reading structure. F006 high: The document has no semantic structure |
be-inclusivelegible-text | issues | high | The rendered page contains zero text characters, so no information is available to read. F001 critical: The homepage is completely blank |
be-inclusivezoom-reflow-targets-and-media | issues | high | The viewport meta element is absent; Chrome uses a 980px layout viewport at the 360px device width. F003 high: The mobile viewport is not configured |
follow-best-practicesno-console-errors | pass | high | No authored scripts exist and the page load produced no observed uncaught application exception; Lighthouse failed solely because no content painted. |
follow-best-practicessound-document-and-assets | issues | high | The server returns zero bytes as application/octet-stream; the browser finds no authored doctype, uses windows-1252, and has no charset declaration. F007 high: The response is not an authored HTML document |
follow-best-practicesbrowser-platform-hygiene | pass | high | No scripts, inputs, permission calls, or libraries are present, so the inspected page exposes no deprecated API, paste-prevention, prompt-on-load, or vulnerable-library behavior. |
be-discoverabletitle-and-description | issues | high | The document title is empty and there is no meta description. F008 high: Title and description are missing |
be-discoverablecrawlable-and-mobile-friendly | issues | high | There are no links, no viewport meta, and /robots.txt contains only "empty OK" rather than robots directives. F009 high: Crawler and mobile discovery basics are missing |
be-discoverablecanonical-and-indexing-signals | issues | high | No canonical is present; sitemap.xml contains "empty OK" rather than XML; every tested nonexistent URL returns 200, creating soft-404 indexing signals. F010 high: Indexing signals are malformed or absent |
be-discoverablestructured-and-shareable-metadata | issues | high | The public homepage has no Open Graph fields and no JSON-LD, so shares and entity discovery have no descriptive metadata. F011 medium: Share and entity metadata are absent |
be-private-and-securesecure-transport-and-headers | issues | high | HTTPS is used, but CSP, HSTS, and X-Content-Type-Options are all absent. F012 high: Baseline transport security headers are absent |
be-private-and-securedata-minimisation-and-third-parties | pass | high | Tracker and HAR captures found zero third-party origins, zero trackers, zero cookies, and no exposed secrets. |

be-private-and-securedefensive-browser-policies | issues | high | The response has no clickjacking protection, Referrer-Policy, or Permissions-Policy. F013 medium: Defensive browser policies are absent |
be-resilientprogressive-enhancement | issues | high | Raw HTML is zero bytes and the rendered DOM is also empty; no core content exists with or without JavaScript. F014 critical: No core content exists with or without JavaScript |
be-resilientresilient-runtime-behaviour | not-applicable | high | No overlays, asynchronous dependencies, or dynamic state exist. |
be-resilientoffline-and-installable | not-applicable | high | This empty public domain exposes no app-like task for which installability is meaningful. |
be-resilientnetwork-and-http-failure-states | issues | high | A deliberately nonexistent path returns 200 with "empty OK" instead of a useful 404 state or recovery navigation. F004 high: Error and recovery states are misleading |
be-internationalisedlang-dir-and-logical-properties | issues | high | The root html element has no lang or dir attribute. F015 medium: Document language is not declared |
be-internationalisedlocale-aware-data | not-applicable | high | No dates, numbers, currency, durations, or locale-sensitive data are rendered. |
be-internationalisedtime-zone-correctness | not-applicable | high | No time or event data exists. |
be-trustworthyno-dark-patterns | pass | high | Load captures contain no consent wall, upsell, disguised ad, or other deceptive interaction. |
be-trustworthyhumane-error-handling | not-applicable | high | No form exists. |
be-trustworthytrustworthy-input-assistance | not-applicable | high | No input exists. |
be-trustworthysafe-commercial-and-account-flows | not-applicable | high | No commercial, consent, authentication, or account flow exists. |
be-sustainableoptimised-assets | not-applicable | high | No images or decorative assets are present. |
be-sustainableno-wasteful-work | pass | high | Trace reports no long tasks and HAR shows only 234 transferred bytes with no background or third-party requests. |
be-sustainablethird-party-and-media-budget | pass | high | No media, fonts, third-party requests, scripts, or animations are present. |
be-agent-readystructured-agent-capabilities | not-applicable | high | The site exposes no task or capability for an agent; agent-facing tooling is not applicable to this blank endpoint. |
be-agent-readyon-device-inference | not-applicable | high | There is no user task that would benefit from on-device inference. |
be-memory-efficientno-leak-under-repeated-interaction | not-applicable | high | The static blank page has no representative interaction to repeat; fabricating one would not test a real session behavior. |
be-memory-efficientbounded-footprint | pass | high | Single-state heap is 741,336 self-size bytes with 26,257 V8 nodes; the authored DOM has only three elements and no scripts, proportionate to an empty page. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | There is no authored script, handler, timer, observer, or dynamic DOM on the inspected page; the heap summary shows no Detached* constructor among top populations. |
