All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	Dark-media computed-style probe compared app and editorial surfaces. F1 medium: The knowledge article ignores the user’s dark color preference.
respect-user-preferences `respects-reduced-motion`	issues	high	Reduced-motion emulation plus getAnimations and CSS media-rule inspection. F2 medium: The main app does not reduce its continuous animation for reduced-motion users.
respect-user-preferences `respects-contrast`	issues	medium	prefers-contrast emulation plus computed styles and Lighthouse contrast audit. F3 low: The app has no explicit response to increased-contrast preference.
implement-natural-interactions `view-transitions`	pass	high	Recorded core journey and DOM API/state inspection showed immediate, coherent state transitions without disorienting motion.
implement-natural-interactions `scroll-driven-animations`	not-applicable	high	No scroll narrative, carousel, parallax, or progress animation is required on the audited core, settings, login, results or article templates.
implement-natural-interactions `physical-gestures`	not-applicable	high	The audited desktop/mobile web task uses tap/click controls and has no gesture-only surface that needs physical gesture mapping.
provide-guided-navigation `scroll-state-aware-chrome`	pass	high	Representative screenshots and route probes show persistent, compact navigation that does not obscure content.
provide-guided-navigation `anchored-positioning`	pass	high	Menus and contextual controls remain associated with their triggers in the inspected DOM and viewport captures.
provide-guided-navigation `directs-attention`	pass	high	The GO control and speed gauge provide a singular visual target; the recorded flow visibly progresses through measurement to results.
maximize-content-reduce-noise `no-intrusive-interruptions`	pass	high	The consent dialog is legally contextual and offers same-layer Reject All and Accept actions; rejecting proceeds to the task.
maximize-content-reduce-noise `semantic-dismissible-primitives`	pass	high	Consent controls are named BUTTON elements with explicit reject and preference-center actions.
maximize-content-reduce-noise `reduced-chrome`	issues	high	Core-flow visual capture shows multiple ad blocks competing with the gauge. F4 medium: Advertising competes heavily with the primary speed-test task.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	pass	high	360x800 layout measured 0px horizontal overflow on both app and article templates.
adapt-to-the-form-factor `component-level-responsiveness`	pass	high	App and article content reflowed to 360px without clipping; desktop and mobile captures retained core controls.
adapt-to-the-form-factor `input-modality-aware`	issues	high	Geometry and focus probes measured undersized menu/result controls. F5 medium: Several interactive controls are too small for reliable touch input.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	Homepage DOM exposes Speedtest by Ookla and a prominent GO action; screenshot/video confirm visual priority.
support-core-task-success `primary-flow-completion`	pass	high	The 70-second active probe completed at /result/19459942607 with download 30.96, upload 56.81 and ping 13.
support-core-task-success `clear-system-state-and-recovery`	pass	high	Video showed progress gauge, server identity, metrics and completion; result offers Change Server and a repeat GO action.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse and trace timings directly measured startup performance. F6 high: Cold-load performance misses the LCP target by a wide margin.
be-fast-and-stable `visual-stability`	pass	high	Mobile layout CLS was 0.0087, article CLS was 0 and Lighthouse CLS was 0.00004.
be-fast-and-stable `efficient-main-thread`	issues	high	Lighthouse and trace long-task/TBT measurements. F7 medium: Script execution blocks responsiveness during startup.
be-fast-and-stable `efficient-resource-delivery`	issues	high	HAR totals and third-party byte attribution. F8 high: The initial page transfers a disproportionate third-party script payload.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Lighthouse unused JavaScript audit. F9 high: Most of the shipped JavaScript is unused during startup.
be-inclusive `names-roles-labels`	issues	high	axe-core full-document violation scan after rejecting consent. F10 high: Focusable hidden ad containers and unnamed image roles create serious accessibility failures.
be-inclusive `sufficient-contrast`	pass	high	Lighthouse accessibility score 0.96 had no color-contrast failure; visual captures show strong light/dark contrast.
be-inclusive `structure-and-focus`	issues	high	axe landmark, region and heading checks. F11 medium: The app lacks a main landmark and has heading-order errors.
be-inclusive `legible-text`	pass	high	Computed body text is 16px in the app and 14.496px in the article; desktop/mobile captures remain readable.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	Mobile reflow metrics plus objective target geometry. F12 medium: Touch targets remain undersized across app and content templates.
follow-best-practices `no-console-errors`	pass	high	Lighthouse errors-in-console audit scored 1 with no logged browser errors.
follow-best-practices `sound-document-and-assets`	pass	high	DOM confirms HTML doctype, UTF-8-rendered content, viewport metadata and modern SVG imagery with alt text.
follow-best-practices `browser-platform-hygiene`	pass	high	Lighthouse best-practices scored 1.00; resource DOM confirms high-priority scripts are async or module, not parser-blocking classic scripts.
be-discoverable `title-and-description`	pass	high	All five representative paths expose distinct titles, descriptions and H1 content.
be-discoverable `crawlable-and-mobile-friendly`	pass	high	Discoverability found non-shell raw HTML with title/H1/description and 47% word coverage; mobile layouts had viewport metadata and no overflow.
be-discoverable `canonical-and-indexing-signals`	pass	high	Canonical URLs exist on representative pages; robots.txt and sitemap.xml returned 200 with explicit route indexes.
be-discoverable `structured-and-shareable-metadata`	issues	high	Article has canonical/description/Open Graph title but no JSON-LD. F13 low: The public knowledge article lacks Article structured data.
be-private-and-secure `secure-transport-and-headers`	pass	high	HTTPS plus HSTS preload, nosniff, DENY framing, referrer and permissions policies were directly observed.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	Tracker and HAR origin attribution. F14 high: The pre-task page has an excessive tracking and third-party footprint.
be-private-and-secure `in-context-permissions-and-modern-auth`	pass	high	Permissions Policy limits sensitive features; no unsolicited permission prompt occurred; email/password fields use email/current-password autocomplete.
be-private-and-secure `defensive-browser-policies`	issues	high	Headers and cookie primitives directly inspected policy values and flags. F15 medium: Cookie and CSP defenses are incomplete.
be-resilient `progressive-enhancement`	pass	high	Raw HTML is not a JS shell and retains title, H1 and description; editorial content is server-visible.
be-resilient `resilient-runtime-behaviour`	pass	high	The full active speed test completed without console errors and exposed repeat/server-change controls.
be-resilient `offline-and-installable`	not-applicable	high	A bandwidth measurement requires a live network, and the site manifest contains icons only; offline/installability is not a meaningful core-task expectation here.
be-resilient `network-and-http-failure-states`	issues	high	Invalid-route test directly exercised the site error state. F16 medium: The 404 state provides no explanation or clear recovery action.
be-internationalised `lang-dir-and-logical-properties`	pass	high	English and German probes set lang correctly; CSS inspection found logical properties and locale links include RTL Arabic.
be-internationalised `locale-aware-data`	issues	high	German settings route and selected date/time defaults were directly inspected. F17 medium: German localisation keeps US date/time defaults and leaves substantial account copy untranslated.
be-internationalised `time-zone-correctness`	not-applicable	medium	Audited flows show instantaneous local measurements, not scheduled or cross-zone events; no user-visible time-zone conversion surface was present.
be-trustworthy `no-dark-patterns`	pass	high	Consent screenshot shows explicit Reject All and I Accept actions with equivalent visual weight and one-click operation.
be-trustworthy `humane-error-handling`	issues	high	Invalid-route DOM directly inspected the recovery copy and actions. F18 low: The not-found page states only an error code.
be-trustworthy `trustworthy-input-assistance`	pass	high	Expanded login form has labels plus autocomplete=email and current-password; settings radios are labeled.
be-trustworthy `safe-commercial-and-account-flows`	pass	high	No purchase/checkout was in scope; login presents privacy/terms links and no irreversible or coercive action was observed.
be-sustainable `optimised-assets`	pass	high	Images primitive found five SVG assets, all with alt text and no legacy raster formats.
be-sustainable `no-wasteful-work`	issues	high	Lighthouse main-thread and unused-JS evidence shows avoidable startup work. F7 medium: Script execution blocks responsiveness during startup.
be-sustainable `third-party-and-media-budget`	issues	high	HAR and tracker captures quantify third-party byte/origin cost. F14 high: The pre-task page has an excessive tracking and third-party footprint.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	No declared agent-facing intent, machine action surface, or workflow delegation requirement exists for this public speed-measurement UI.
be-agent-ready `on-device-inference`	not-applicable	high	The product exposes no AI summarisation/generation feature, so on-device model selection is not applicable.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	high	Rejected-consent baseline vs 10 repeated theme interactions grew only 915,583 bytes (1.5%), with no Detached/listener/timer constructor among top retained constructors.
be-memory-efficient `bounded-footprint`	pass	high	Post-consent retained self size was about 62–63 MB and remained bounded across the repeated interaction comparison.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	Heap constructor summaries found no Detached DOM, listener or timer constructor in top retained objects after repetition.
