All 58 atomic check outcomes

Principle / check	Status	Confidence	Evidence or reason
respect-user-preferences `respects-color-scheme`	pass	high	Light preference produces a light surface and dark preference produces a dark surface; both remain usable.
respect-user-preferences `respects-reduced-motion`	pass	high	Three 300 ms animations exist normally; under reduce, getAnimations() returned none and scroll behavior remained auto.
respect-user-preferences `respects-contrast`	pass	high	Forced-colors mode mapped links to yellow, text to white, and surfaces to black with visible borders and controls.
implement-natural-interactions `view-transitions`	issues	high	No View Transition declarations were found for this multi-page site. F01 medium: Page-to-page changes are abrupt because cross-document View Transitions are not enabled.
implement-natural-interactions `scroll-driven-animations`	pass	medium	No scroll-linked effects or scroll-handler-driven animation were observed; therefore no main-thread scroll animation anti-pattern is present.
implement-natural-interactions `physical-gestures`	pass	high	Horizontal content rows use native scrolling with scroll-snap declarations, and no custom pointer-driven gesture was required for the core flow.
provide-guided-navigation `scroll-state-aware-chrome`	issues	high	The homepage is 18,490 px tall and has no scroll-state-aware chrome or progress indicator. F02 low: Long pages provide no scroll-state-aware header or progress feedback.
provide-guided-navigation `anchored-positioning`	not-applicable	high	No tooltip, anchored popover, or edge-sensitive menu is part of the representative paths, so anchor positioning has no applicable target.
provide-guided-navigation `directs-attention`	pass	high	Breadcrumbs, a named jump link to #ms, and descriptive download controls guide users from the track heading to the primary action.
maximize-content-reduce-noise `no-intrusive-interruptions`	pass	high	No popup or interstitial obscures content on load; primary content begins immediately.
maximize-content-reduce-noise `semantic-dismissible-primitives`	pass	high	The transient homepage search UI uses a native dialog; no ad-hoc modal was present on audited paths.
maximize-content-reduce-noise `reduced-chrome`	pass	medium	Chrome is limited to compact navigation/search and content cards; the music and download content dominates each path.
adapt-to-the-form-factor `responsive-no-horizontal-scroll`	pass	high	Both templates report scrollWidth=clientWidth=360, zero horizontal overflow, and a valid viewport meta tag.
adapt-to-the-form-factor `component-level-responsiveness`	pass	high	Rendered CSS contains @container/container-type and cards reflow across desktop and mobile captures.
adapt-to-the-form-factor `input-modality-aware`	issues	high	Focus outlines are present, but several key controls measure below comfortable touch size. F03 medium: Several navigation and search controls are too small for comfortable touch use.
support-core-task-success `clear-purpose-and-primary-action`	pass	high	The site purpose, search, categories, track names, and detail-page download intent are explicit in Persian.
support-core-task-success `primary-flow-completion`	pass	high	A listing leads to a detail page with a jump link, playable audio, and direct 320/128/64 kbps MP3 links.
support-core-task-success `clear-system-state-and-recovery`	issues	high	A nonexistent path redirects to the homepage with no error state or explanation. F04 high: Unknown URLs silently redirect to the homepage instead of showing a clear not-found state.
be-fast-and-stable `good-core-web-vitals`	issues	high	Lighthouse LCP is 7.1 s and performance is 0.66; CLS is 0 and TBT is 80 ms. F05 high: Mobile Largest Contentful Paint is well outside the good range.
be-fast-and-stable `visual-stability`	pass	high	Home and detail observed CLS=0 with no shifts; Lighthouse also reports CLS 0.
be-fast-and-stable `efficient-main-thread`	pass	high	Trace TBT is 40 ms with one 90 ms long task; Lighthouse TBT is 80 ms, both indicating a light main thread.
be-fast-and-stable `efficient-resource-delivery`	issues	high	Ten parser-inserted high-priority stylesheets and weak image caching create avoidable delivery cost. F06 medium: Image caching and render-blocking CSS leave substantial delivery savings.
be-fast-and-stable `trim-unused-and-duplicate-code`	pass	medium	Only 66.8 KB of scripts transferred and Lighthouse did not flag large unused/duplicate JavaScript; the only minification saving was about 3 KiB CSS.
be-inclusive `names-roles-labels`	issues	high	Twenty-six images lack alt text, search is unlabeled, and the detail template contains many unnamed links. F07 high: Search, imagery, and many detail-page links lack usable accessible names.
be-inclusive `sufficient-contrast`	issues	high	Lighthouse fails the color-contrast audit and muted search text is visibly faint. F08 high: Some foreground/background combinations fail WCAG contrast minimums.
be-inclusive `structure-and-focus`	issues	high	Focus is visible, but the homepage has no main landmark and H1 follows several H2s. F09 medium: The homepage lacks a main landmark and uses a non-sequential heading hierarchy.
be-inclusive `legible-text`	pass	medium	Body and heading text are unclipped and comfortably spaced in RTL layouts on audited mobile pages.
be-inclusive `zoom-reflow-targets-and-media`	issues	high	Scaling is permitted and pages reflow, but several core targets are below 44×44 px. F10 medium: Touch-target sizing weakens usability under mobile reflow.
follow-best-practices `no-console-errors`	pass	high	Lighthouse best-practices score is 1.0 and errors-in-console passed.
follow-best-practices `sound-document-and-assets`	pass	high	HTML has doctype/UTF-8; images reserve dimensions, aspect ratio audits pass, and Lighthouse best practices scores 1.0.
follow-best-practices `browser-platform-hygiene`	pass	high	No deprecated API, inspector, prompt-on-load, vulnerable-library, paste-prevention, or BFCache failure was reported.
be-discoverable `title-and-description`	pass	high	Both representative pages expose unique descriptive titles and meta descriptions.
be-discoverable `crawlable-and-mobile-friendly`	pass	high	Links use real hrefs, viewport meta is present, robots permits public content, and Lighthouse SEO is 1.0.
be-discoverable `canonical-and-indexing-signals`	pass	high	Pages return 200, canonical URLs and index/follow metadata are present, and robots.txt points to a populated sitemap index.
be-discoverable `structured-and-shareable-metadata`	pass	high	Home and track detail contain JSON-LD plus accurate Open Graph title, description, URL, and image/audio metadata.
be-private-and-secure `secure-transport-and-headers`	issues	high	HTTPS/HSTS are present and no secrets were found, but CSP is absent and five cookies lack Secure. F11 high: The site lacks a Content Security Policy and sets analytics cookies without Secure or an explicit same-site posture.
be-private-and-secure `data-minimisation-and-third-parties`	issues	high	Legacy Google Analytics sets persistent __utm identifiers, including a 400-day cookie. F12 medium: Legacy Google Analytics tracking creates persistent identifiers without visible minimisation evidence.
be-private-and-secure `in-context-permissions-and-modern-auth`	pass	medium	No permission prompt occurs on load; sign-in offers OTP and Google identity rather than requiring a password alone.
be-private-and-secure `defensive-browser-policies`	issues	high	HSTS, nosniff, SAMEORIGIN and Referrer-Policy are present, but Permissions-Policy and CSP are absent. F13 medium: Permissions-Policy is absent, leaving browser capabilities unrestricted by response policy.
be-resilient `progressive-enhancement`	pass	high	Raw HTML preserves 100% reported content coverage, titles, H1s and descriptions on both core templates.
be-resilient `resilient-runtime-behaviour`	pass	medium	Search/dialog, content rows, audio and download controls render without clipping or broken async state on audited paths.
be-resilient `offline-and-installable`	not-applicable	high	This is a public music/download content MPA rather than an installed application; a service worker exists, but installability is not required for its core task.
be-resilient `network-and-http-failure-states`	issues	high	A nonexistent URL redirects to an ordinary homepage and does not expose a truthful, recoverable 404 state. F14 high: HTTP not-found handling produces a misleading success-like homepage state.
be-internationalised `lang-dir-and-logical-properties`	pass	high	The document uses lang=fa-IR and dir=rtl; rendered CSS includes logical inline properties and RTL layouts are correct.
be-internationalised `locale-aware-data`	pass	medium	The track page presents Persian month/year and RTL-localized date/time content rather than raw machine timestamps.
be-internationalised `time-zone-correctness`	not-applicable	high	Audited music pages do not coordinate cross-zone events, recurring schedules, or user-entered times, so time-zone/DST handling is not applicable.
be-trustworthy `no-dark-patterns`	pass	medium	No confirmshaming, forced continuity, disguised ad control, autoplay, or consent wall appeared; registration is optional.
be-trustworthy `humane-error-handling`	pass	medium	The sign-in UI uses native required-field validation and clear labels; the visible mobile-number step is simple and reversible.
be-trustworthy `trustworthy-input-assistance`	issues	high	Telephone, password and email fields omit relevant autocomplete tokens; only OTP fields use one-time-code. F15 medium: Sign-in fields omit key autocomplete tokens.
be-trustworthy `safe-commercial-and-account-flows`	pass	medium	The account entry clearly offers mobile/email, one-time code and Google sign-in without hidden pricing, continuity, or purchase commitment.
be-sustainable `optimised-assets`	issues	high	All 100 audited images use legacy formats; four are oversized and images transfer 1.37 MB. F16 medium: The homepage ships only legacy image formats and several oversized images.
be-sustainable `no-wasteful-work`	pass	medium	Script transfer is 66.8 KB, TBT is 40–80 ms, no autoplay media exists, and no wasteful background loop was observed.
be-sustainable `third-party-and-media-budget`	pass	medium	Third-party analytics transfers about 18 KB, media does not autoplay, and audio uses preload=none; most subdomain bytes directly serve content images/audio.
be-agent-ready `structured-agent-capabilities`	not-applicable	high	The public music catalogue has no declared agent-facing transaction/tool surface; WebMCP absence is an opportunity, not a failure.
be-agent-ready `on-device-inference`	not-applicable	high	The audited search/download experience has no inference task that requires an on-device language model or summarizer.
be-memory-efficient `no-leak-under-repeated-interaction`	pass	medium	After ten search open/close cycles, DOM nodes were unchanged and JS heap moved only 13 KB; snapshot totals rose about 1.8% with no constructor accumulation.
be-memory-efficient `bounded-footprint`	pass	high	Baseline heap self-size is 9.64 MB for a content-heavy page with 1,436 DOM elements, proportionate to the page.
be-memory-efficient `no-detached-dom-or-unbounded-listeners`	pass	medium	Neither heap summary reports Detached* constructors; constructor counts remain stable and DOM node count does not grow after repeated interaction.
