All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	issues	high	Dark screenshot stays light; CSS contains no color-scheme adaptation. F01 medium: The site ignores the user’s dark color-scheme preference.
respect-user-preferences `respects-reduced-motion`	pass	high	Reduced-motion emulation matched and reported zero running animations; the menu has no non-essential motion to suppress.
respect-user-preferences `respects-contrast`	pass	high	Forced-colors/high-contrast screenshot retains visible text, icons, controls and media boundaries.
implement-natural-interactions `view-transitions`	issues	high	Menu state swaps without View Transition or equivalent spatial cue. F02 low: Mobile menu state changes are abrupt.
implement-natural-interactions `scroll-driven-animations`	not-applicable	high	The audited templates contain no parallax, scrollytelling, reveal, or other scroll-linked animation.
implement-natural-interactions `physical-gestures`	not-applicable	high	No swipe, pull, draggable carousel, or gesture-driven control was present in the representative paths.
provide-guided-navigation `scroll-state-aware-chrome`	issues	high	The long listing has no position-aware navigation or progress cue. F03 low: Long listings provide no scroll-position-aware orientation.
provide-guided-navigation `anchored-positioning`	not-applicable	high	No tooltip, popover, floating menu, or viewport-edge overlay requiring anchored positioning was found.
provide-guided-navigation `directs-attention`	pass	high	Route H1s, active sort/quality states, and the large player action make focus movement and current context visually clear.
maximize-content-reduce-noise `no-intrusive-interruptions`	pass	high	No load-time modal, full-screen interstitial, or obscuring banner appeared on any representative path.
maximize-content-reduce-noise `semantic-dismissible-primitives`	not-applicable	high	No dialog, disclosure, transient popover, or modal flow was present; the semantic probe found zero dialog/popover/details elements.
maximize-content-reduce-noise `reduced-chrome`	pass	high	Mobile removes the desktop sidebar and gives nearly the full viewport to the two-column content/player surfaces.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	pass	high	Homepage and detail report 360px scroll/client width, viewport meta, and zero horizontal overflow.
adapt-to-the-form-factor `component-level-responsiveness`	issues	high	Reusable preview cards adapt through page-level layout only; no container query support is present. F04 low: Repeated content cards respond only to viewport rules, not their container.
adapt-to-the-form-factor `input-modality-aware`	issues	high	Visible keyboard outline passes, but several main controls are below 44px in one or both dimensions. F05 medium: Several primary controls are too small for reliable touch input.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	Listing, search and detail headings state the current task; the detail’s large play control is immediately visible.
support-core-task-success `primary-flow-completion`	pass	high	Search POST redirects to /find/music/ with 40 results, and a representative detail loads a readyState=4 player with a visible play action.
support-core-task-success `clear-system-state-and-recovery`	issues	high	The 404 is labelled but offers no explicit recovery action beside the error. F06 medium: The custom 404 state does not offer an explicit recovery action.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse LCP is 2.2s and TBT 0ms, but CLS is 0.208 and therefore outside the good range. F07 high: Load-time layout stability misses the good Core Web Vitals range.
be-fast-and-stable `visual-stability`	issues	high	Lab CLS is 0.208; 48 images lack explicit dimensions, a clear late-layout risk. F07 high: Load-time layout stability misses the good Core Web Vitals range. F08 medium: Image and critical-resource delivery is inefficient.
be-fast-and-stable `efficient-main-thread`	pass	high	Trace found one 60.88ms task, only 10.88ms TBT; Lighthouse TBT was 0ms.
be-fast-and-stable `efficient-resource-delivery`	issues	high	Below-fold images are eager, most lack dimensions/srcset, and confirmed synchronous classic scripts/styles occupy the critical path. F08 medium: Image and critical-resource delivery is inefficient.
be-fast-and-stable `trim-unused-and-duplicate-code`	issues	high	Lighthouse estimates 199 KiB unused JS, including repeated ad-provider and page-inapplicable video code. F09 medium: The page ships substantial unused JavaScript.
be-inclusive `names-roles-labels`	issues	high	Search lacks an associated label, page landmarks are absent, and two images lack alt. F10 medium: Search and page regions are not fully exposed semantically.
be-inclusive `sufficient-contrast`	issues	high	Lighthouse found 2.72:1 brand and 3.02:1 active-control contrast failures. F11 medium: Some branded and active-control text fails minimum contrast.
be-inclusive `structure-and-focus`	issues	high	Focus is visible and heading order is logical, but no main/nav landmarks exist. F12 medium: Document landmarks are missing.
be-inclusive `legible-text`	issues	high	Single-line uppercase card titles are repeatedly clipped mid-phrase on narrow screens. F13 low: Card titles are clipped rather than allowed to communicate complete meaning.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	Reflow has no horizontal overflow and viewport allows scaling, but multiple controls are only 28px high. F05 medium: Several primary controls are too small for reliable touch input.
follow-best-practices `no-console-errors`	issues	high	Lighthouse recorded an uncaught notify.js TypeError and two 404 thumbnails. F14 medium: The page loads with uncaught and network errors.
follow-best-practices `sound-document-and-assets`	issues	high	Doctype/UTF-8 are valid, but 48 images omit intrinsic dimensions and two assets return 404. F15 medium: Image markup does not reserve intrinsic space.
follow-best-practices `browser-platform-hygiene`	issues	high	Deprecated API, BFCache, source-map, prompt and paste audits pass; third-party cookie inspector issues remain. F16 low: Browser inspector issues are generated by third-party cookie behavior.
be-discoverable `title-and-description`	pass	high	Homepage, search and detail each have descriptive, route-specific titles/descriptions; title/H1/description survive raw HTML.
be-discoverable `crawlable-and-mobile-friendly`	pass	high	Real href links, viewport meta and valid robots are present; Lighthouse SEO scored 100 and crawler content is non-empty.
be-discoverable `canonical-and-indexing-signals`	pass	high	Public routes return successful status in normal operation, expose route-specific canonicals, and are not noindex; robots allows normal crawling.
be-discoverable `structured-and-shareable-metadata`	issues	high	Detail video Open Graph/JSON-LD is strong, but homepage Organization.name is empty and homepage has no Open Graph metadata. F17 low: Homepage entity/share metadata is incomplete.
be-private-and-secure `secure-transport-and-headers`	issues	high	HTTPS passes, but key security headers are absent and __suvt is insecure/SameSite=None/400-day. F18 high: Transport is HTTPS, but browser defenses and cookie flags are weak.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	82/96 requests and ~3.0MB are third-party across eight origins, with third-party cookies. F19 high: Third-party advertising and tracking dominate the request surface.
be-private-and-secure `in-context-permissions-and-modern-auth`	pass	high	No geolocation/notification prompt occurs on load and audited public paths expose no authentication flow requiring a passkey assessment.
be-private-and-secure `defensive-browser-policies`	issues	high	HSTS, clickjacking, CSP, referrer and permissions defenses are all absent. F20 high: Defensive browser policies are absent.
be-resilient `progressive-enhancement`	pass	high	Raw HTML is 47.9KB, not a JS shell, and preserves title/H1/description plus substantial content; crawler screenshot remains usable.
be-resilient `resilient-runtime-behaviour`	pass	high	Mobile menu and player remain in-viewport; detail/search/listing render without clipped overlays, and normal player route reaches readyState=4.
be-resilient `offline-and-installable`	not-applicable	high	This is a server-backed public media/search MPA rather than an install-oriented app; its minimal manifest has no name/icons/start_url and no service worker controls the page.
be-resilient `network-and-http-failure-states`	issues	high	An audited detail request intermittently reached a raw Cloudflare 522 page with no site retry/recovery state. F21 medium: Origin/network failures fall through to an infrastructure error page.
be-internationalised `lang-dir-and-logical-properties`	issues	high	lang=en is correct, but physical left/right CSS is present with no observed logical/dir adaptation. F22 low: The English page declares lang correctly but its layout is not translation/writing-mode ready.
be-internationalised `locale-aware-data`	issues	high	Relative-age labels are rendered as hard-coded English across public routes, without observed locale adaptation. F23 low: Relative dates are hard-coded in English.
be-internationalised `time-zone-correctness`	not-applicable	high	No event scheduling, absolute timestamps, recurrence, user time zones or DST-sensitive task is exposed.
be-trustworthy `no-dark-patterns`	issues	high	Ad tiles mimic content recommendation cards and lack a prominent Advertisement label. F24 high: Advertising cards imitate content recommendations.
be-trustworthy `humane-error-handling`	not-applicable	high	The search form has no required or constrained fields and no validation flow; blank/term searches are navigation rather than data mutation.
be-trustworthy `trustworthy-input-assistance`	pass	high	The only input is a simple free-text search; its purpose is clear from placeholder/context and no personal, address, payment or credential autofill is relevant.
be-trustworthy `safe-commercial-and-account-flows`	not-applicable	high	No checkout, subscription, consent setting, sign-in, or account-management flow is exposed in the audited public routes.
be-sustainable `optimised-assets`	issues	high	Most images are WebP and not oversized, but nearly all lack responsive sources and below-fold loading is eager. F25 medium: Responsive asset delivery leaves avoidable bytes and work.
be-sustainable `no-wasteful-work`	issues	high	Initial listing observation fetches 2.26MB by XHR, led by three third-party preview MP4s before explicit intent. F26 high: The listing fetches megabytes of third-party media before explicit user intent.
be-sustainable `third-party-and-media-budget`	issues	high	Third parties consume ~3.0MB and 82 requests, disproportionate to a thumbnail listing. F27 high: Third-party/media cost is disproportionate to the listing’s core thumbnails.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	No WebMCP/agent-tool intent is exposed, and the emerging capability is not necessary to complete the public browse/search/play tasks.
be-agent-ready `on-device-inference`	not-applicable	high	No summarisation, generation, language assistance, or other inference task is part of the observed experience.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	medium	After 20 real mobile-menu toggles, the post snapshot remained small (7.17MB); no Detached constructor surfaced. Variation versus the 6.70MB fresh-load baseline is confounded by random content/ads and does not establish retained unbounded growth.
be-memory-efficient `bounded-footprint`	pass	medium	Heap summaries are 6.70–7.17MB with about 101k–106k heap nodes; DOM probe reports 1,395 elements, proportionate to a 50-card media listing.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	medium	No Detached* constructor appears in either summary’s top constructors and 20 menu toggles do not show evidence of accumulating detached UI.
