All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | pass | high | Light emulation produced rgb(253,252,252) and a light-theme body; dark emulation produced the dark surface, so the page follows the system scheme. |
respect-user-preferencesrespects-reduced-motion | issues | high | Ten animations remained running under prefers-reduced-motion: reduce, including morph, scale, sweep, rotate, and gradient loops with 4.3s to 1,498.5s durations. F01 medium: Motion preference is ignored |
respect-user-preferencesrespects-contrast | pass | high | Forced-colors/high-contrast capture preserves text, controls, borders, icons, and links. |
implement-natural-interactionsview-transitions | issues | high | Rendered DOM/CSS evidence contains no view-transition declarations for accessible state/navigation changes; navigation is implemented without the modern transition primitive. F02 low: State changes do not use View Transitions |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No scroll-linked parallax, scrollytelling, carousel, or reveal interaction was present on the audited Gemini app entry surface. |
implement-natural-interactionsphysical-gestures | not-applicable | high | No swipe, pull-to-reveal, removable list, or other physical gesture surface was available in the signed-out representative flow. |
provide-guided-navigationscroll-state-aware-chrome | not-applicable | high | The signed-out app entry is a single-viewport prompt surface; the long release-notes route redirects to a separate gemini.google origin and was treated as a related path, not app chrome. |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip or edge-positioned popover was exposed in the signed-out primary flow; the consent surface is a modal dialog, not an anchored transient overlay. |
provide-guided-navigationdirects-attention | pass | high | Entry, download, help, release-notes, and sign-in screenshots each expose a clear heading and visually dominant next control. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | On first load the consent dialog obscures the primary prompt; at 360x800 it fills almost the entire viewport and initially exposes only “Read more”, not the accept/reject controls. F03 high: Consent blocks the product on first load |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | The consent UI is a custom MAT-DIALOG-CONTAINER with role=dialog, aria-modal=false, and no accessible name, despite visually blocking the app. F04 high: Consent dialog semantics do not match its modal behavior |
maximize-content-reduce-noisereduced-chrome | pass | high | Behind the consent layer the signed-out app devotes the viewport to a single prompt composer and minimal navigation; download and help pages retain clear content hierarchy. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | pass | high | At 360x800 the app and release notes reported 0px horizontal overflow, valid viewport metadata, and mobile-specific layout. |
adapt-to-the-form-factorcomponent-level-responsiveness | pass | high | Runtime CSS inspection found a container rule, and app/download controls reflow from wide to narrow captures without overflow. |
adapt-to-the-form-factorinput-modality-aware | issues | high | The target probe found multiple actionable links only 17–18px high and a “More options” button 22px high, below robust touch-target expectations. F05 medium: Several targets are too short for dependable touch use |
support-core-task-successclear-purpose-and-primary-action | pass | high | The H1 “Meet Gemini, your personal AI assistant” and prominently labelled prompt textbox communicate purpose and next action. |
support-core-task-successprimary-flow-completion | issues | high | The representative signed-out prompt flow cannot begin until the full-screen consent layer is expanded and answered; the core composer is visibly present but blocked. F06 high: Consent adds a blocking detour to the primary prompt flow |
support-core-task-successclear-system-state-and-recovery | pass | high | Sign-in state, model selection, disabled/open sidebar states, AI accuracy disclaimer, and explicit consent choices are visibly labelled. |
be-fast-and-stablegood-core-web-vitals | issues | high | Mobile Lighthouse measured LCP 28.5s, FCP 6.7s, TBT 940ms, Speed Index 11.5s, and performance score 0.35; a separate trace measured LCP 2.32s, showing strong condition sensitivity but confirming the throttled experience is poor. F07 high: Throttled mobile load misses the Core Web Vitals performance bar |
be-fast-and-stablevisual-stability | pass | high | Lighthouse CLS was 0.002 and the mobile layout observer measured 0.048, both within the good range; release notes measured zero shift. |
be-fast-and-stableefficient-main-thread | issues | high | Lighthouse reported 4.2s main-thread work, 2.1s JavaScript execution, and 940ms TBT; the trace also recorded three long tasks and 48ms TBT. F08 high: JavaScript keeps the main thread busy during startup |
be-fast-and-stableefficient-resource-delivery | issues | high | Initial load transferred 5.33MB across 95 requests, including 3.71MB scripts and 1.37MB fonts; Lighthouse found redirect, document-latency, cache, font-display, and dependency-tree opportunities. F09 high: Critical resource delivery is too heavy and delayed |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | Lighthouse estimated 1,106KiB unused JavaScript and 58KiB unused CSS on the signed-out entry surface. F10 medium: Large unused CSS and JavaScript ship on the entry surface |
be-inclusivenames-roles-labels | issues | high | Lighthouse found the role=dialog surface has no accessible name and a visible-label/accessibility-name mismatch. F11 high: The blocking dialog lacks a reliable accessible name |
be-inclusivesufficient-contrast | pass | high | Lighthouse accessibility scored 0.96 without a contrast failure, and forced-colors capture retained readable text/control boundaries. |
be-inclusivestructure-and-focus | pass | high | The app exposes H1s and named controls; keyboard focus probes show UA or custom focus outlines on the tested menu, tool, link, language, and consent controls. |
be-inclusivelegible-text | pass | high | Across desktop, 360px mobile, Arabic RTL, download, help, and release-notes captures, text remains unclipped and readable with clear line spacing. |
be-inclusivezoom-reflow-targets-and-media | pass | high | Viewport metadata does not disable scaling and 360px layouts reflow without horizontal overflow; no essential audio/video content was present on the audited surfaces. |
follow-best-practicesno-console-errors | pass | high | Lighthouse best-practices scored 1.00 and did not report browser errors or uncaught exceptions. |
follow-best-practicessound-document-and-assets | issues | high | The document has HTML doctype and UTF-8, but all five img elements lack width/height attributes and one visible SVG is delivered at 150px intrinsic width for a 40px display. F12 low: Image elements omit intrinsic dimensions |
follow-best-practicesbrowser-platform-hygiene | issues | high | Lighthouse reports three reasons preventing back/forward cache restoration, despite the overall best-practices category passing. F13 medium: The page is not eligible for reliable BFCache restoration |
be-discoverabletitle-and-description | pass | high | The entry has title “Google Gemini” and a descriptive meta description; download and release notes provide path-specific descriptions. |
be-discoverablecrawlable-and-mobile-friendly | pass | high | Lighthouse SEO scored 1.00; viewport metadata is present, robots allows the root and download route, and crawlable policy/help links use real hrefs. |
be-discoverablecanonical-and-indexing-signals | pass | high | The root returned HTTP 200 with canonical https://gemini.google.com/, robots references a successful 315-URL sitemap, and locale/path variants are represented. |
be-discoverablestructured-and-shareable-metadata | pass | high | Entry and release-notes pages expose JSON-LD plus Open Graph metadata consistent with visible Gemini content. |
be-private-and-securesecure-transport-and-headers | issues | high | HTTPS, CSP, nosniff, and X-Frame-Options are present, but the CSP permits unsafe-inline/unsafe-eval, HSTS and Referrer-Policy are absent, and GOOGLE_ABUSE_EXEMPTION is reported without Secure and with SameSite=None. F14 high: Defensive response policy has material gaps |
be-private-and-securedata-minimisation-and-third-parties | pass | high | The consent surface offers Reject all; tracker matching found no known tracker domains. Eight service origins were contacted, all within Google-controlled infrastructure, so no independent leaky third party was demonstrated. |
be-private-and-securein-context-permissions-and-modern-auth | pass | high | No geolocation/notification request was observed on load; authentication hands off to Google Accounts over HTTPS, whose first step is clearly labelled. |
be-private-and-securedefensive-browser-policies | issues | high | Clickjacking and Trusted Types defenses are present, but HSTS and Referrer-Policy are absent and the broad CSP includes unsafe-inline/unsafe-eval. F14 high: Defensive response policy has material gaps |
be-resilientprogressive-enhancement | issues | high | Raw server HTML contains only 3% of rendered content words, no H1, and produces an almost blank crawler screenshot; the primary app content depends on JavaScript. F15 high: Primary content is an almost empty no-JavaScript shell |
be-resilientresilient-runtime-behaviour | pass | high | App controls, consent layer, Arabic RTL layout, and 360px layouts rendered without clipping or horizontal overflow; repeated sidebar state changes did not increase heap totals. |
be-resilientoffline-and-installable | issues | high | This app-like site exposes no web app manifest and the CSP sets manifest-src none; no installable/offline web fallback was found. F16 medium: The web app has no installable or offline fallback |
be-resilientnetwork-and-http-failure-states | issues | high | A representative unknown route returns a bare 404 page with “That’s all we know” and no retry, home, search, or recovery action. F17 medium: Unknown routes offer no recovery action |
be-internationalisedlang-dir-and-logical-properties | pass | high | The Arabic route sets lang=ar and dir=rtl, mirrors the layout, and has no horizontal overflow; English routes set appropriate en-US/en-GB language values. |
be-internationalisedlocale-aware-data | pass | high | The sitemap publishes 63 locale variants for each major path and the Arabic UI is translated rather than merely relabelled at the document level. |
be-internationalisedtime-zone-correctness | not-applicable | high | No time-zone-sensitive event, appointment, deadline, or local-time transaction appears in the audited app entry, download, help, or release-note surfaces. |
be-trustworthyno-dark-patterns | issues | high | On mobile, consent choices are withheld behind “Read more” while the modal blocks the core product; users cannot initially choose Accept all or Reject all. F18 high: Consent choices are initially hidden behind disclosure |
be-trustworthyhumane-error-handling | not-applicable | high | Gemini’s audited surfaces contain no conventional editable form with required/invalid submission states; the Google Accounts form is a separate origin and was not submitted. |
be-trustworthytrustworthy-input-assistance | not-applicable | high | The Gemini prompt is a free-form contenteditable, not an address, payment, sign-in, or sign-up field where autocomplete tokens apply. |
be-trustworthysafe-commercial-and-account-flows | pass | high | The audited account handoff clearly identifies Google sign-in, offers account creation and guest-mode guidance, and exposes privacy/terms links; no purchase or subscription commitment was entered. |
be-sustainableoptimised-assets | pass | high | Only 15.4KB of images transferred and three of five image resources use modern SVG; the one PNG is a 24px brand mark. |
be-sustainableno-wasteful-work | issues | high | A nearly empty signed-out prompt surface transfers 5.33MB, including 3.71MB scripts and 1.37MB fonts, before the user performs a task. F19 high: Startup work is disproportionate to the signed-out surface |
be-sustainablethird-party-and-media-budget | issues | high | 70 of 95 initial requests and 5.19MB of 5.33MB are classified off the gemini.google.com origin; Google-owned gemini.gstatic.com and fonts.gstatic.com dominate bytes. F20 medium: Cross-origin service assets dominate the load budget |
be-agent-readystructured-agent-capabilities | not-applicable | high | WebMCP is emerging and no explicit agent-facing scope is declared. A probe found no navigator MCP surface or registered machine-readable tools, so this is recorded as an opportunity rather than a failure. |
be-agent-readyon-device-inference | not-applicable | high | Gemini is itself a server-backed AI product, but no audited user task established a need for browser built-in on-device LanguageModel or Summarizer APIs. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | After ten representative sidebar open/close attempts, heap nodes fell from 1,193,867 to 1,186,030 and self size fell from 66.39MB to 65.37MB; no retained-growth signal was observed. |
be-memory-efficientbounded-footprint | issues | high | The signed-out entry retains about 65–66MB across roughly 1.19M V8 heap nodes before a conversation begins, disproportionate to the visible single prompt surface and consistent with the 5.33MB/46-script load. F21 medium: Initial heap footprint is high for a one-control entry state |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | No Detached* constructor appears among top retained constructors; closure count fell from 111,177 to 109,746 after repeated interaction and overall heap totals decreased. |
