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/light-grey surface and the DOM reports color-scheme: normal under prefers-color-scheme: dark. F01 high: The public experience ignores the system dark-colour preference. |
respect-user-preferencesrespects-reduced-motion | pass | high | evaluate under prefers-reduced-motion: reduce found zero active animations. |
respect-user-preferencesrespects-contrast | pass | high | Lighthouse passed colour contrast and the preference probe confirmed prefers-contrast emulation with relevant CSS rules present. |
implement-natural-interactionsview-transitions | issues | high | The interaction video shows the consent layer disappearing and content changing without a directional or continuity cue; no active View Transition was observed. F02 medium: Major state changes are abrupt. |
implement-natural-interactionsscroll-driven-animations | pass | high | The recorded smooth scroll produced no long interaction task and no active scripted animation was found under reduced motion. |
implement-natural-interactionsphysical-gestures | pass | high | The public page relies on native scrolling; the recorded scroll remained controllable and no custom gesture trap was observed. |
provide-guided-navigationscroll-state-aware-chrome | issues | high | The interaction video shows a long content page with no progress or scroll-state response in its navigation chrome. F03 medium: The site chrome does not communicate scroll state. |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip, anchored popover, or edge-positioned menu was present in the audited unauthenticated paths. |
provide-guided-navigationdirects-attention | issues | high | The interaction video shows the consent layer disappearing and content changing without a directional or continuity cue; no active View Transition was observed. F02 medium: Major state changes are abrupt. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | Desktop, Explore and login captures all open with a viewport-dimming consent or login layer over the content; Explore is blocked by login before interaction. F04 high: Load-time overlays repeatedly obscure the primary content. |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | The document probe finds a DIV role=dialog aria-modal=true; no <dialog> is present. F05 medium: The cookie modal is an ad-hoc ARIA dialog rather than the platform dialog primitive. |
maximize-content-reduce-noisereduced-chrome | pass | high | Desktop captures devote the page body to imagery and discovery content with a compact top navigation outside the prompted overlays. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | At 360x800, layout reports scrollWidth 929 versus visual viewport 360, 569 px overflow; the screenshot clips headings and most of the consent dialog off-screen. F06 critical: The mobile homepage is horizontally clipped and unusable. |
adapt-to-the-form-factorcomponent-level-responsiveness | pass | high | Document probe confirms container-query CSS is shipped, and desktop cards adapt across the homepage and Explore layouts. |
adapt-to-the-form-factorinput-modality-aware | issues | high | The focused skip link computes outline:none and box-shadow:none; Lighthouse fails target-size for the Pinterest app controls. F07 high: Keyboard focus and touch-target treatment are insufficient. |
support-core-task-successclear-purpose-and-primary-action | pass | high | The first viewport clearly states “Create the life you love on Pinterest” with Join and Log in actions. |
support-core-task-successprimary-flow-completion | pass | high | The representative unauthenticated login journey reaches a labelled email/password form with login, Google and signup choices; completion requiring real credentials was not fabricated. |
support-core-task-successclear-system-state-and-recovery | issues | high | A nonexistent URL renders the normal homepage rather than a clear 404/recovery state, while HAR records two 404 API calls and Lighthouse logs them as console errors. F08 high: Failure and recovery states are misleading or absent. |
be-fast-and-stablegood-core-web-vitals | issues | high | Lighthouse reports LCP 18.4 s, CLS 0.463 and TBT 510 ms (performance score 0.23); trace corroborates 4.21 s LCP and two long tasks in a separate run. F09 critical: Core Web Vitals are far outside good thresholds. |
be-fast-and-stablevisual-stability | issues | high | Lighthouse reports LCP 18.4 s, CLS 0.463 and TBT 510 ms (performance score 0.23); trace corroborates 4.21 s LCP and two long tasks in a separate run. F09 critical: Core Web Vitals are far outside good thresholds. |
be-fast-and-stableefficient-main-thread | issues | high | Lighthouse reports LCP 18.4 s, CLS 0.463 and TBT 510 ms (performance score 0.23); trace corroborates 4.21 s LCP and two long tasks in a separate run. F09 critical: Core Web Vitals are far outside good thresholds. |
be-fast-and-stableefficient-resource-delivery | issues | high | HAR captures 159 requests and 6,436,533 transferred bytes, including 78 scripts (2.90 MB), 45 images (2.46 MB) and 4 media requests (820 KB). F10 high: The unauthenticated landing page ships a very heavy dependency graph. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | HAR records 78 script requests and 2.90 MB script transfer; Lighthouse identifies large first-party bundles and missing/403 source maps. F11 high: JavaScript dominates the initial load. |
be-inclusivenames-roles-labels | pass | high | Lighthouse passed image-alt and accessible naming audits; login inputs have programmatic Email and Password labels. |
be-inclusivesufficient-contrast | pass | high | Lighthouse colour-contrast audit passed on the homepage. |
be-inclusivestructure-and-focus | issues | high | The focused skip link computes outline:none and box-shadow:none; Lighthouse fails target-size for the Pinterest app controls. F07 high: Keyboard focus and touch-target treatment are insufficient. |
be-inclusivelegible-text | pass | high | Desktop screenshots show readable typography, comfortable line lengths and clear heading hierarchy on the public landing and Explore pages. |
be-inclusivezoom-reflow-targets-and-media | issues | high | The 360 px screenshot is clipped with 569 px horizontal overflow and Lighthouse fails the target-size audit. F12 medium: Reflow and touch target accessibility fail on mobile. |
follow-best-practicesno-console-errors | issues | high | Lighthouse records a FedCM NetworkError and two first-party 404 requests during load; HAR confirms 404 responses. F13 medium: The page logs avoidable runtime and network errors. |
follow-best-practicessound-document-and-assets | issues | high | The image probe reports 36/36 images without width/height, 27 oversized, 35 below-fold not lazy, 11 without srcset and no modern-format images. F14 medium: Image delivery lacks robust sizing and responsive optimisation. |
follow-best-practicesbrowser-platform-hygiene | issues | high | Lighthouse reports a BFCache blocker and missing/403 source maps for large first-party modules. F15 medium: Browser platform hygiene has measurable regressions. |
be-discoverabletitle-and-description | pass | high | DOM reports title “Pinterest - India” and a descriptive meta description. |
be-discoverablecrawlable-and-mobile-friendly | issues | high | Discoverability reports 1% rendered-word coverage, isJsShell:true and no raw-HTML h1; the crawler screenshot contains almost no core content. F17 high: The homepage core content is effectively a JavaScript shell for non-JS crawlers. |
be-discoverablecanonical-and-indexing-signals | issues | high | The live DOM canonical is https://www.pinterest.com/ while the audited URL is https://in.pinterest.com/; Lighthouse fails the canonical audit. F16 high: The India homepage publishes an invalid cross-locale canonical. |
be-discoverablestructured-and-shareable-metadata | pass | high | The page exposes JSON-LD plus six Open Graph tags matching Pinterest’s visible public identity. |
be-private-and-securesecure-transport-and-headers | issues | high | Cookies audit finds five cookies flagged insecure, including non-Secure g_state, _b and _routing_id and multiple SameSite=None cookies; CSP permits unsafe-inline and Permissions-Policy is missing. No client secrets were found. F18 high: Cookie and CSP posture is weaker than the transport baseline. |
be-private-and-securedata-minimisation-and-third-parties | issues | high | Tracker evidence finds nine third-party origins and Pinterest tracker endpoints; HAR attributes 137/159 requests and 6.28 MB to cross-origin hosts before consent was acted on. F19 high: Substantial tracking and third-party activity occurs on the initial experience. |
be-private-and-securein-context-permissions-and-modern-auth | issues | high | Login exposes email/password and Google/QR options; no passkey/WebAuthn affordance was observed. F20 medium: The observed login surface does not offer phishing-resistant authentication. |
be-private-and-securedefensive-browser-policies | issues | high | Cookies audit finds five cookies flagged insecure, including non-Secure g_state, _b and _routing_id and multiple SameSite=None cookies; CSP permits unsafe-inline and Permissions-Policy is missing. No client secrets were found. F18 high: Cookie and CSP posture is weaker than the transport baseline. |
be-resilientprogressive-enhancement | issues | high | Raw HTML is 1.1 MB yet contains only 7 content tokens and 1% of rendered words; without JavaScript the homepage is a shell. A board detail fares better at 57%. F21 high: The homepage does not progressively expose its core discovery content. |
be-resilientresilient-runtime-behaviour | issues | high | At 360x800, layout reports scrollWidth 929 versus visual viewport 360, 569 px overflow; the screenshot clips headings and most of the consent dialog off-screen. F06 critical: The mobile homepage is horizontally clipped and unusable. |
be-resilientoffline-and-installable | pass | high | Runtime confirms a service worker interface and linked manifest; the public shell has an installability foundation. Offline task completion was not claimed beyond this check’s app foundation. |
be-resilientnetwork-and-http-failure-states | issues | high | The synthetic missing route shows the normal homepage and HAR records failed first-party calls without a visible recovery state. F22 high: HTTP failures do not lead to intentional recovery UI. |
be-internationalisedlang-dir-and-logical-properties | pass | high | HTML lang=en, 37 hreflang variants, and logical-property CSS were observed. |
be-internationalisedlocale-aware-data | not-applicable | high | The representative public paths display no dates, currencies, numbers, durations or calendar data requiring locale formatting. |
be-internationalisedtime-zone-correctness | not-applicable | high | The representative public paths expose no event or time-zone-sensitive data. |
be-trustworthyno-dark-patterns | pass | high | Cookie dialog presents Reject all, Let me choose and Accept all at the same level; login and signup commitments are plainly labelled. |
be-trustworthyhumane-error-handling | issues | high | After requestSubmit() with empty email and password, the captured form remains visually unchanged with no clear inline error or recovery instruction. F23 medium: The login form did not expose visible empty-submit guidance in the exercised state. |
be-trustworthytrustworthy-input-assistance | pass | high | Observed signup/login fields use email, current-password/new-password and bday autocomplete tokens. |
be-trustworthysafe-commercial-and-account-flows | issues | high | Login exposes email/password and Google/QR options; no passkey/WebAuthn affordance was observed. F20 medium: The observed login surface does not offer phishing-resistant authentication. |
be-sustainableoptimised-assets | issues | high | HAR transfers 2.46 MB of images and 820 KB of media; image audit finds 27 oversized and zero modern-format images. F24 high: The media payload is disproportionate for the first unauthenticated viewport. |
be-sustainableno-wasteful-work | issues | high | The landing page performs 159 requests, including 78 scripts and 19 fetch/XHR requests, while Lighthouse reaches only 0.23 performance. F25 high: Initial background work and fetching are excessive. |
be-sustainablethird-party-and-media-budget | issues | high | HAR transfers 2.46 MB of images and 820 KB of media; image audit finds 27 oversized and zero modern-format images. F24 high: The media payload is disproportionate for the first unauthenticated viewport. |
be-agent-readystructured-agent-capabilities | not-applicable | high | Pinterest exposes no declared agent-facing transaction or productivity surface in the audited unauthenticated scope; this emerging capability is treated as an opportunity, not a failure. |
be-agent-readyon-device-inference | not-applicable | high | No audited task calls for on-device generation or summarisation, so built-in inference is not required. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | After ten top-to-bottom scroll cycles, heap self size fell from 71.37 MB to 70.21 MB; node count rose only 1.8% across independently loaded snapshots, with no evidence of unbounded retained growth. |
be-memory-efficientbounded-footprint | issues | high | Heap summary contains about 1.12 million V8 snapshot nodes and 71.4 MB self size; runtime reports 56.0 MB used JS heap and 1,294 DOM elements. Repeated scroll did not increase total self size. F26 medium: The baseline memory footprint is high for an unauthenticated landing page. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | Neither heap summary lists Detached* constructors among retained populations, and total self size did not grow after repeated scrolling. |
