This report has no published overall score. Blocked and not-run checks are not passes. A coverage-complete report means every check has a judged outcome; it does not mean every check passed.
All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | pass | high | Dark-condition and normal captures show a coherent dark surface; CSS probe found color-scheme support. |
respect-user-preferencesrespects-reduced-motion | issues | high | With prefers-reduced-motion:reduce matched, getAnimations() still returned a running 3000ms animation with an unbounded iteration count. F05 medium: An animation continues under reduced-motion preference |
respect-user-preferencesrespects-contrast | pass | high | Text and controls remain visible in captured dark UI; no forced-colors-specific failure was observed. |
implement-natural-interactionsview-transitions | pass | high | The audited pages use direct navigation and do not add disorienting state-transition motion. |
implement-natural-interactionsscroll-driven-animations | pass | high | CSS probe found scroll-timeline support and layout observation found no scroll-induced long-task pattern on the templates. |
implement-natural-interactionsphysical-gestures | not-applicable | high | No swipe, drag, carousel, or gesture-driven control exists on the audited templates. |
provide-guided-navigationscroll-state-aware-chrome | pass | high | The long services directory keeps compact navigation chrome and content remains directly reachable while scrolling. |

maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | DOM probing found no `<dialog>`, popover, or role=dialog; consent actions are `div[role=button]`, while the panel overlays content on both templates. F09 medium: Cookie consent uses custom controls without a semantic dialog |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | DOM probing found no `<dialog>`, popover, or role=dialog; consent actions are `div[role=button]`, while the panel overlays content on both templates. F09 medium: Cookie consent uses custom controls without a semantic dialog |
maximize-content-reduce-noisereduced-chrome | pass | high | The homepage dedicates nearly all visible space to the search task; services are grouped without ads in the captured state. |

support-core-task-successprimary-flow-completion | issues | high | A direct navigation to the search results URL redirected to “Please confirm that you are not a robot”; the cookie panel also overlaps the challenge in the captured viewport. F01 high: Automated search reaches a CAPTCHA instead of results |
support-core-task-successclear-system-state-and-recovery | issues | high | A direct navigation to the search results URL redirected to “Please confirm that you are not a robot”; the cookie panel also overlaps the challenge in the captured viewport. F01 high: Automated search reaches a CAPTCHA instead of results |
be-fast-and-stablegood-core-web-vitals | issues | high | The trace and Lighthouse independently measured LCP at about 5.85s; Lighthouse performance was 0.76 and LCP score 0.15. F06 high: Largest Contentful Paint is slow |

be-inclusivelegible-text | pass | high | Desktop screenshots show readable hierarchy and body copy at the native desktop viewport. |
be-inclusivezoom-reflow-targets-and-media | issues | high | DOM measurements show consent actions are 32px high, and the 360px screenshots are scaled desktop layouts because the viewport meta tag is absent. F15 medium: Consent targets are short and the page does not reflow at mobile width |

follow-best-practicessound-document-and-assets | pass | high | DOM/Lighthouse confirmed HTML doctype, charset, language, and no img dimension/alt failures (the page uses no img elements). |

be-private-and-securesecure-transport-and-headers | issues | high | Headers evidence found CSP allows unsafe-eval and lacks Permissions-Policy; the CSP does otherwise use a nonce and HSTS/XFO/nosniff are present. F08 medium: Defensive browser policy coverage is incomplete |
be-private-and-securedata-minimisation-and-third-parties | issues | high | The screenshot shows the consent banner while HAR recorded 18 third-party requests (296,026 bytes), including mc.yandex.ru, and the cookie audit found 14 first-party cookies, many SameSite=None and up to 400 days. F07 high: Tracking requests and persistent identifiers occur while consent is still being requested |
be-private-and-securein-context-permissions-and-modern-auth | not-applicable | high | Authentication and permission-grant flows were not part of the public search/templates audited. |

be-resilientresilient-runtime-behaviour | pass | high | Captured controls and consent panel render without clipping at desktop and expose explicit settings/recovery actions. |
be-resilientoffline-and-installable | issues | high | The manifest declares display:standalone and a start_url, but the page probe found no controlling service worker. F14 medium: The installable manifest has no service-worker-backed offline behaviour |
be-resilientnetwork-and-http-failure-states | issues | high | A direct navigation to the search results URL redirected to “Please confirm that you are not a robot”; the cookie panel also overlaps the challenge in the captured viewport. F01 high: Automated search reaches a CAPTCHA instead of results |

be-trustworthyhumane-error-handling | issues | high | A direct navigation to the search results URL redirected to “Please confirm that you are not a robot”; the cookie panel also overlaps the challenge in the captured viewport. F01 high: Automated search reaches a CAPTCHA instead of results |

be-trustworthysafe-commercial-and-account-flows | not-applicable | high | No commercial, subscription, checkout, or account-management flow exists on the audited public templates. |

be-sustainablethird-party-and-media-budget | issues | high | HAR measured 387,242 transferred bytes, of which 296,026 bytes (76%) and 18 of 30 requests were third-party; the simple homepage has no `<img>` content. F12 medium: Most transferred bytes come from third-party origins |
be-agent-readystructured-agent-capabilities | issues | high | The page probe found no WebMCP capability, Lighthouse agentic-browsing scored 0.5, and the representative search URL redirected to an anti-bot challenge. F13 medium: The public search task has no structured agent capability and blocks automation |
be-agent-readyon-device-inference | not-applicable | high | The core task is remote web search; on-device generation or summarisation is not required for this surface. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | After ten real search-input edit/focus cycles, DOM node count changed only 201 to 203; heap snapshot size rose about 2.8%, insufficient evidence of retained unbounded growth. |
be-memory-efficientbounded-footprint | pass | high | Heap summaries measured about 8.7 to 9.0MB self size, proportionate for this React-like search homepage. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | No Detached* constructor appeared in the summary; repeated interaction added only two live DOM nodes. |
