All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	Preference-emulated screenshots and computed media/style probes were compared. F003 medium: The site does not adapt to the user’s dark color preference.
respect-user-preferences `respects-reduced-motion`	issues	high	Preference-emulated screenshots and computed media/style probes were compared. F004 low: Reduced-motion preference leaves smooth scrolling enabled.
respect-user-preferences `respects-contrast`	pass	high	Preference-emulated screenshots and computed media/style probes were compared.
implement-natural-interactions `view-transitions`	pass	medium	The covered MPA links use ordinary full-document navigation; no SPA state morph or abrupt custom transition was present, so native navigation remained predictable.
implement-natural-interactions `scroll-driven-animations`	pass	medium	CSS inspection found no animation-timeline and layout observers found no scroll long tasks; the site uses native scrolling rather than main-thread scroll animation.
implement-natural-interactions `physical-gestures`	pass	medium	Core tasks use links, form submission, and map controls rather than gesture-only handlers; no custom pointer trap was observed.
provide-guided-navigation `scroll-state-aware-chrome`	pass	medium	Mobile captures retain a compact branded header/search entry and clear section headings while content scrolls.
provide-guided-navigation `anchored-positioning`	issues	medium	Desktop/mobile screenshots, semantic navigation inspection, and overlay geometry were reviewed. F001 critical: The consent wall interrupts content before any user request and is not exposed as a semantic modal.
provide-guided-navigation `directs-attention`	pass	medium	The first content viewport clearly labels “Wetter für Deutschland heute” and puts forecast/radar/warning choices directly above the map.
maximize-content-reduce-noise `no-intrusive-interruptions`	issues	high	Load screenshots, fixed-overlay probe, and full-page mobile length were reviewed. F001 critical: The consent wall interrupts content before any user request and is not exposed as a semantic modal.
maximize-content-reduce-noise `semantic-dismissible-primitives`	issues	high	Load screenshots, fixed-overlay probe, and full-page mobile length were reviewed. F001 critical: The consent wall interrupts content before any user request and is not exposed as a semantic modal.
maximize-content-reduce-noise `reduced-chrome`	issues	high	Load screenshots, fixed-overlay probe, and full-page mobile length were reviewed. F015 medium: The landing page buries core weather content in a very long mixed feed.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	issues	high	Five archetypes were measured at 360×800 and keyboard focus/control geometry was probed. F002 critical: The consent UI is wider than a phone viewport and clips both primary choices.
adapt-to-the-form-factor `component-level-responsiveness`	issues	high	Five archetypes were measured at 360×800 and keyboard focus/control geometry was probed. F002 critical: The consent UI is wider than a phone viewport and clips both primary choices.
adapt-to-the-form-factor `input-modality-aware`	issues	high	Five archetypes were measured at 360×800 and keyboard focus/control geometry was probed. F010 medium: Some controls are too small or lose a visible focus indicator.
support-core-task-success `clear-purpose-and-primary-action`	issues	high	Homepage, Berlin forecast, radar, search result, article, and 404 recovery journeys were exercised. F017 high: The core local-forecast and article journeys can be blocked by an unusable consent step.
support-core-task-success `primary-flow-completion`	issues	high	Homepage, Berlin forecast, radar, search result, article, and 404 recovery journeys were exercised. F017 high: The core local-forecast and article journeys can be blocked by an unusable consent step.
support-core-task-success `clear-system-state-and-recovery`	pass	high	Radar displays a plain-language loading state; search returns named results; the real 404 names the error and links to news, home, and search.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse, trace summary, layout observers, HAR summary, and image evidence were combined. F005 high: Largest Contentful Paint is slow on the primary landing page.
be-fast-and-stable `visual-stability`	pass	high	Layout observers measured CLS 0 on home/listing/radar/search, 0.00002 on city, and 0.025 on article, all below the 0.1 good threshold.
be-fast-and-stable `efficient-main-thread`	pass	high	Trace and layout observers found zero long tasks and Lighthouse TBT was 49.7ms.
be-fast-and-stable `efficient-resource-delivery`	issues	high	Lighthouse, trace summary, layout observers, HAR summary, and image evidence were combined. F006 medium: Render-blocking and unused/duplicated front-end code delay useful content.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Lighthouse, trace summary, layout observers, HAR summary, and image evidence were combined. F006 medium: Render-blocking and unused/duplicated front-end code delay useful content.
be-inclusive `names-roles-labels`	issues	high	axe-core, Lighthouse accessibility, semantics, focus/control geometry, and screenshots were combined. F009 medium: Accessibility semantics and reading order contain repeatable defects.
be-inclusive `sufficient-contrast`	issues	high	axe-core, Lighthouse accessibility, semantics, focus/control geometry, and screenshots were combined. F008 high: Several text elements fail minimum color contrast.
be-inclusive `structure-and-focus`	issues	high	axe-core, Lighthouse accessibility, semantics, focus/control geometry, and screenshots were combined. F009 medium: Accessibility semantics and reading order contain repeatable defects.
be-inclusive `legible-text`	issues	high	axe-core, Lighthouse accessibility, semantics, focus/control geometry, and screenshots were combined. F008 high: Several text elements fail minimum color contrast.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	axe-core, Lighthouse accessibility, semantics, focus/control geometry, and screenshots were combined. F007 critical: The viewport configuration disables user zoom.
follow-best-practices `no-console-errors`	issues	high	Lighthouse diagnostics plus doctype/charset/image and DOM probes were reviewed. F011 low: A JavaScript console error occurs during load.
follow-best-practices `sound-document-and-assets`	issues	high	Lighthouse diagnostics plus doctype/charset/image and DOM probes were reviewed. F012 medium: Image delivery and dimensions waste bandwidth and create avoidable layout risk.
follow-best-practices `browser-platform-hygiene`	pass	high	Lighthouse diagnostics plus doctype/charset/image and DOM probes were reviewed.
be-discoverable `title-and-description`	pass	high	All six representative pages retained title, H1, and meta description in raw HTML.
be-discoverable `crawlable-and-mobile-friendly`	pass	high	Discoverability coverage was 53–81%, no page was a JS shell, anchors have hrefs, and a viewport meta is present (zoom restriction is reported under inclusivity).
be-discoverable `canonical-and-indexing-signals`	pass	high	Homepage returned 200 with canonical, INDEX/FOLLOW robots meta, hreflang, robots.txt, and a populated sitemap; the error test returned HTTP/2 404.
be-discoverable `structured-and-shareable-metadata`	pass	high	The page exposes ItemList, VideoObject, WebSite SearchAction, Organization JSON-LD plus complete Open Graph fields.
be-private-and-secure `secure-transport-and-headers`	issues	high	HTTPS headers, cookies, secrets scan, tracker inventory, and HAR third-party summary were reviewed. F013 high: Defensive browser policy is incomplete and one cookie is insecurely scoped.
be-private-and-secure `data-minimisation-and-third-parties`	pass	high	Tracker inventory found no known tracker domains before consent; third parties were chiefly first-party asset subdomains and Usercentrics CMP endpoints.
be-private-and-secure `in-context-permissions-and-modern-auth`	not-applicable	high	No permission request or authentication flow exists on the representative public, read-only paths, so passkey/auth judgement is not applicable.
be-private-and-secure `defensive-browser-policies`	issues	high	HTTPS headers, cookies, secrets scan, tracker inventory, and HAR third-party summary were reviewed. F013 high: Defensive browser policy is incomplete and one cookie is insecurely scoped.
be-resilient `progressive-enhancement`	pass	high	Raw server HTML preserved 53–81% of rendered words and title/H1/description across all six templates; none was an empty JS shell.
be-resilient `resilient-runtime-behaviour`	pass	high	No-JS crawler views, manifest/service-worker probe, loading surface, search result, and real HTTP 404 recovery were reviewed.
be-resilient `offline-and-installable`	not-applicable	high	The audited surface is a public MPA content/weather service and no offline intent is declared; the manifest supports home-screen presentation, but offline operation is not treated as a required core outcome.
be-resilient `network-and-http-failure-states`	pass	high	A real HTTP/2 404 renders a clear German explanation with routes back to current news, homepage, and search.
be-internationalised `lang-dir-and-logical-properties`	pass	medium	html lang is de-DE and alternate locales are declared via hreflang; no RTL locale is offered on this German page.
be-internationalised `locale-aware-data`	pass	medium	Berlin renders German dates (Do 23.07.2026), decimal commas, narrow no-break spacing, °C, l/m², km/h, and hPa.
be-internationalised `time-zone-correctness`	pass	medium	Location-specific sunrise/sunset and hourly forecast times are rendered for Berlin alongside the place forecast; no contradictory client-local conversion was observed.
be-trustworthy `no-dark-patterns`	issues	high	Consent choice geometry, search form semantics, and humane 404 recovery were reviewed. F016 high: The consent choice architecture is visually coercive and hard to compare on mobile.
be-trustworthy `humane-error-handling`	pass	high	The required search form produces a clear result page; the 404 explains the failure without blame and offers recovery links.
be-trustworthy `trustworthy-input-assistance`	pass	high	Search inputs use type=search, name=q, required, and explicit accessible labels; autocomplete off is reasonable for live place suggestions.
be-trustworthy `safe-commercial-and-account-flows`	not-applicable	high	No checkout, subscription management, account, or authentication journey was in the representative public scope.
be-sustainable `optimised-assets`	issues	high	HAR transfer/third-party totals, image audit, trace, and idle long-task signals were reviewed. F012 medium: Image delivery and dimensions waste bandwidth and create avoidable layout risk.
be-sustainable `no-wasteful-work`	pass	high	Trace/layout observers found no long tasks, and the no-consent tracker run found no known analytics tracker activity.
be-sustainable `third-party-and-media-budget`	issues	high	HAR transfer/third-party totals, image audit, trace, and idle long-task signals were reviewed. F006 medium: Render-blocking and unused/duplicated front-end code delay useful content. F012 medium: Image delivery and dimensions waste bandwidth and create avoidable layout risk.
be-agent-ready `structured-agent-capabilities`	issues	high	Raw discoverability, structured metadata, Lighthouse agentic signal, and WebMCP/built-in AI probes were reviewed. F014 medium: The public weather/search experience has no structured agent capability surface.
be-agent-ready `on-device-inference`	not-applicable	high	The core task is retrieval of authoritative server weather data, not local summarisation or generation; an on-device inference feature has no demonstrated use case.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	high	After one warm-up menu cycle, DOM nodes remained exactly 2,558 after 10 and 20 further cycles; heap fell after warm-up and changed only from 9.18MB to 9.59MB between cycles 10 and 20.
be-memory-efficient `bounded-footprint`	pass	high	The baseline heap summary was 7.10MB self size and 108,750 snapshot nodes; the warmed same-session series settled near 9–10MB JS heap for this content-heavy page.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	high	The same-session repeated menu test accumulated zero DOM nodes after warm-up, and the sampled live DOM reported no detached nodes.
