All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | pass | high | Light and dark screenshots show complete surface/logo retinting, and computed html color-scheme follows the selected/system theme. |
respect-user-preferencesrespects-reduced-motion | pass | high | Under prefers-reduced-motion: reduce, getAnimations returned only a finished zero-duration reveal; no auto-advance or essential motion remained. |
respect-user-preferencesrespects-contrast | pass | high | High-contrast screenshot preserves controls and content; the separate normal-theme notice contrast defect is recorded under be-inclusive/sufficient-contrast. |
implement-natural-interactionsview-transitions | issues | medium | The CSS/animation probe found no view-transition rules or API evidence; the only animation under reduced motion was a finished zero-duration reveal. F09 low: State and route changes expose no View Transitions integration. |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No scrollytelling, parallax, carousel, or scroll-linked motion exists on the reachable home/settings archetypes. |
implement-natural-interactionsphysical-gestures | not-applicable | high | No gesture-driven component or scroll carousel exists on the reachable archetypes. |
provide-guided-navigationscroll-state-aware-chrome | not-applicable | high | The reachable homepage is a single viewport and settings uses ordinary document scrolling without affixed chrome needing state adaptation. |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip, anchored menu, or edge-positioned popover was present in the exercised states. |
provide-guided-navigationdirects-attention | pass | high | Settings uses a stable page title, grouped labeled sections, and a clear close route; the 404 gives a direct return action. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | Desktop, light, dark, mobile, results, and settings screenshots all show the persistent notice before interaction. It is dismissible, but it repeatedly consumes prominent viewport space. F03 medium: A metrics notice occupies the full bottom edge on every fresh load and competes with the primary search task. |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | medium | DOM probes report zero <dialog> and zero [popover] elements on home/settings despite the Quick settings overlay surface; controls are assembled from generic page structures. F06 low: Transient settings UI is implemented without dialog or popover semantics. |
maximize-content-reduce-noisereduced-chrome | pass | high | Homepage devotes the main surface to the search control with minimal header/footer chrome. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | Both 360x800 layout captures report hasViewportMeta=false, clientWidth=980 and visualViewport scale=0.367; the mobile screenshots show a miniature desktop interface. F01 high: The page omits a viewport meta tag, so mobile Chrome lays it out at 980 CSS pixels and scales the entire interface down. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | medium | The authored CSS exposed by the DOM and the dedicated probe contained no @container or container-type rules. F10 low: No container-query evidence was found for reusable search/settings components. |
adapt-to-the-form-factorinput-modality-aware | pass | high | Lighthouse target-size passed; primary controls expose names and keyboard focusability, and settings uses native selects/radios/checkboxes. |
support-core-task-successclear-purpose-and-primary-action | pass | high | First viewport clearly presents Brave branding and a single prominent “Ask anything, find anything” search control. |
support-core-task-successprimary-flow-completion | blocked | high | The results route presented a drag-the-slider bot challenge, so result selection and end-to-end completion could not be exercised. F04 high: The representative search flow is blocked by a drag-the-slider bot challenge in the audit environment. |
support-core-task-successclear-system-state-and-recovery | pass | high | The bot state names the verification requirement and the 404 explicitly states failure with “Get back to searching privately”. |
be-fast-and-stablegood-core-web-vitals | issues | medium | Mobile Lighthouse reports LCP 4.1s and FCP 3.2s (performance 80), while the desktop trace records LCP 1.68s and TBT 0ms. The slower common mobile condition is the divergence. F05 medium: Mobile lab loading misses the good LCP threshold despite a fast desktop trace. |
be-fast-and-stablevisual-stability | pass | high | Layout observer measured CLS 0.0065 desktop and 0 mobile; images are SVG and no meaningful jump was observed. |
be-fast-and-stableefficient-main-thread | pass | high | Trace and layout observers recorded zero long tasks and 0ms total blocking time. |
be-fast-and-stableefficient-resource-delivery | pass | high | HAR found no redirects, HTTP errors, missing cache headers, uncompressed text, or render-blocking candidates. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | medium | HAR summary records 72 requests and 516,673 transferred bytes, including 55 scripts (286,474 bytes) and a 128,942-byte stylesheet for a sparse search shell. F11 low: The minimal homepage loads a fragmented script-heavy startup payload. |
be-inclusivenames-roles-labels | pass | high | Lighthouse button-name, link-name and label audits passed; both images have meaningful alt text. |
be-inclusivesufficient-contrast | issues | high | Lighthouse measures #909093 on #39393b at 3.61:1 for 13px text, below the WCAG 4.5:1 minimum. F02 medium: The private-usage-metrics notice uses low-contrast body text. |
be-inclusivestructure-and-focus | issues | high | The document probe found no h1-h6 elements; main and footer landmarks exist, but the page purpose is represented only by logo/controls. F07 low: The homepage has no heading structure. |
be-inclusivelegible-text | pass | high | Desktop/light/dark screenshots show comfortable main text sizing and unclipped labels; the specific notice contrast issue is separately recorded. |
be-inclusivezoom-reflow-targets-and-media | pass | high | Lighthouse reports no user-scaling restriction and target-size passes; no media requiring captions exists. Mobile reflow defect is recorded under responsive layout. |
follow-best-practicesno-console-errors | pass | high | Lighthouse reports no browser errors logged to the console. |
follow-best-practicessound-document-and-assets | pass | high | DOM and Lighthouse confirm HTML doctype and UTF-8; two SVG images have alt text and observed CLS is minimal. |
follow-best-practicesbrowser-platform-hygiene | pass | high | Lighthouse best-practices scored 100; no permission prompt appeared on load and no paste-blocking input behavior was observed. |
be-discoverabletitle-and-description | pass | high | Homepage and settings expose unique descriptive titles and a detailed meta description. |
be-discoverablecrawlable-and-mobile-friendly | issues | high | DOM and both mobile layout captures report no meta viewport and a 980 CSS-pixel layout viewport at scale 0.367. F13 medium: The public homepage lacks the viewport signal required for mobile-friendly indexing and presentation. |
be-discoverablecanonical-and-indexing-signals | pass | high | Homepage returns successfully in browser, exposes a language-qualified canonical, and robots.txt intentionally excludes query-result indexing. |
be-discoverablestructured-and-shareable-metadata | pass | high | Homepage Open Graph site, URL, title, description, locale, and 1200x630 image metadata accurately describe the visible service. |
be-private-and-securesecure-transport-and-headers | pass | high | HTTPS, HSTS, CSP, nosniff, SAMEORIGIN and secure referrer policy are present; zero cookies and zero exposed secrets were found. |
be-private-and-securedata-minimisation-and-third-parties | pass | high | Tracker primitive found no known trackers/third-party origins and cookies primitive found zero cookies; the metrics notice provides a settings opt-out. |
be-private-and-securein-context-permissions-and-modern-auth | not-applicable | high | No authentication surface was exposed, and the location permission action is user-initiated in settings. |
be-private-and-securedefensive-browser-policies | issues | high | The headers primitive confirms CSP, HSTS, nosniff, SAMEORIGIN, and strict-origin-when-cross-origin, but reports Permissions-Policy missing. F08 low: Permissions-Policy is absent despite otherwise strong defensive headers. |
be-resilientprogressive-enhancement | pass | high | Raw response included substantial HTML and metadata rather than an empty mount; settings controls are server-backed POST forms. The crawler-specific fetch was externally rate-limited. |
be-resilientresilient-runtime-behaviour | pass | high | Reachable settings controls and notification remained bounded in screenshots; no cut-off menu or runtime error was observed. |
be-resilientoffline-and-installable | issues | high | The fetched manifest has blank name and short_name and no start_url; the settings probe reports no controlling service worker. F12 low: The app-like search experience advertises a standalone manifest but is not meaningfully installable or offline-capable. |
be-resilientnetwork-and-http-failure-states | pass | high | A real 404 returns HTTP 404 with plain explanation and a recovery link rather than a blank shell. |
be-internationalisedlang-dir-and-logical-properties | pass | high | html lang is en-gb; settings offers a broad language and region selector, and the CSS probe found no physical left/right property use in exposed top-level rules. |
be-internationalisedlocale-aware-data | not-applicable | high | Reachable home/settings states contain no user-facing dates, currency, or locale-sensitive numbers to format. |
be-internationalisedtime-zone-correctness | not-applicable | high | Reachable home/settings states contain no event or time-zone data. |
be-trustworthyno-dark-patterns | pass | high | Settings exposes usage-metrics control and the notice links directly to settings; no forced continuity, disguised ad, confirmshaming, or hidden pricing appeared. |
be-trustworthyhumane-error-handling | not-applicable | high | The primary search field has no required/invalid form state; no validation workflow exists on reachable settings controls. |
be-trustworthytrustworthy-input-assistance | not-applicable | high | No address, payment, sign-in, or sign-up fields exist on the reachable archetypes. |
be-trustworthysafe-commercial-and-account-flows | not-applicable | high | No checkout, subscription purchase, authentication, or account-management flow was entered; the premium link is only a navigation CTA. |
be-sustainableoptimised-assets | pass | high | Image audit found two lightweight modern SVGs with alt text and no legacy raster formats; total image transfer was 8KB. |
be-sustainableno-wasteful-work | pass | high | Trace recorded no long tasks and trackers found no chatty external analytics; network activity settled after load. |
be-sustainablethird-party-and-media-budget | pass | high | No autoplay/media or known tracker origin loaded; CDN-hosted first-party assets total about 490KB and are cached. |
be-agent-readystructured-agent-capabilities | not-applicable | high | Agent-facing capabilities are emerging and no declared WebMCP/agent surface was observable; absence is treated as an opportunity, not a failure. |
be-agent-readyon-device-inference | not-applicable | high | No page feature calls for optional built-in summarisation/language-model inference on the reachable search shell. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | Ten quick-settings attempts produced a one-time DOM increase to 458 elements, then counts remained exactly 458 for every remaining iteration; no unbounded per-iteration growth was observed. |
be-memory-efficientbounded-footprint | pass | high | Baseline heap was 12.71MB self size for 208,219 heap nodes, proportionate to this app shell. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | Heap summaries showed no Detached* constructor among dominant populations, and repeated-interaction DOM counts plateaued rather than accumulating. |
