All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | The dark-condition probe reports color-scheme normal and a white body background while prefers-color-scheme: dark matches; the dark screenshot is visually unchanged. F01 medium: System dark-mode preference is ignored. |
respect-user-preferencesrespects-reduced-motion | pass | high | Reduced-motion probe matched the emulated preference and reported no active document animations. |
respect-user-preferencesrespects-contrast | pass | high | High-contrast screenshot retained visible text and controls, although ordinary-color contrast has separate WCAG issues. |
implement-natural-interactionsview-transitions | issues | high | CSS/DOM probe found zero view-transition rules across the home template. F02 low: Route and state changes do not use View Transitions. |
implement-natural-interactionsscroll-driven-animations | issues | high | CSS inspection found zero animation-timeline or scroll-timeline rules while the page ships Slick carousel JavaScript. F03 low: Carousel/scroll effects rely on legacy scripting rather than declarative timelines. |
implement-natural-interactionsphysical-gestures | pass | high | Carousel uses CSS transforms/transitions and click controls; no custom pointermove gesture handler was observed. |
provide-guided-navigationscroll-state-aware-chrome | issues | high | CSS inspection found no scroll-state container rules or scroll-timeline rules on a 10,563px-tall mobile page. F04 low: Page chrome does not respond to scroll state. |
provide-guided-navigationanchored-positioning | issues | high | DOM/CSS inspection found no anchor-name, position-anchor, or position-try rules; overlays are Bootstrap div modals. F05 low: Menus and overlays use manually positioned legacy components. |
provide-guided-navigationdirects-attention | pass | high | Listing and detail screenshots show breadcrumbs and clearly labeled next actions. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | Desktop and 360px screenshots show a modal and backdrop obscuring the manga content before interaction. F06 high: A large notification modal blocks the primary content on every home-page load. |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | DOM probe found zero dialog and popover elements while the screenshot shows a modal built from div.modal markup. F07 medium: The blocking notification is an ad-hoc div modal rather than a native dialog/popover. |
maximize-content-reduce-noisereduced-chrome | pass | high | Outside the separately reported auto-modal, detail/listing templates devote the viewport primarily to content. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | pass | medium | Representative screenshots and DOM/evaluate inspection found the expected outcome for Layout adapts to narrow viewports with no horizontal overflow and no fixed pixel widths forcing a desktop layout on mobile; viewport meta present; fluid scaling and intrinsic sizing rather than brittle breakpoints. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | high | CSS inspection found zero container rules despite cards and sidebars being reused at varied widths. F08 low: Components only use viewport-era responsiveness. |
adapt-to-the-form-factorinput-modality-aware | issues | high | Focus probe returned outline none and box-shadow none for sampled links and inputs; multiple interactive targets are only 16px high. F09 high: Keyboard focus is visually absent and many targets are too short. |
support-core-task-successclear-purpose-and-primary-action | pass | high | Detail page names the manga, summarizes it, and prominently presents START READING. |
support-core-task-successprimary-flow-completion | issues | high | The detail-page probe resolved START READING to aovheroes.com/rds/... rather than a chapter on vymanga.com. F10 critical: The main “START READING” action points to an unrelated advertising redirect. |
support-core-task-successclear-system-state-and-recovery | pass | high | The exercised unknown route renders a clear 404 explanation and Home recovery link. |
be-fast-and-stablegood-core-web-vitals | issues | high | Lighthouse measured LCP 20.3s, Speed Index 8.0s, and performance score 0.61; an unthrottled trace measured LCP 2.257s, showing network/device sensitivity. F11 high: Mobile loading performance misses the LCP target badly. |
be-fast-and-stablevisual-stability | pass | high | Layout primitive measured CLS 0.0196 and Lighthouse measured 0.0104, both in the good range. |
be-fast-and-stableefficient-main-thread | pass | high | Trace found one 86.69ms long task and 36.69ms TBT; Lighthouse measured 17ms TBT. |
be-fast-and-stableefficient-resource-delivery | issues | high | HAR reports 68 requests, 5,754,771 transferred bytes, 4.38MB images, four VeryHigh-priority stylesheets, and synchronous legacy scripts. F12 high: The initial page is a 5.75MB load dominated by images and parser-discovered CSS/scripts. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | Lighthouse estimates 308KiB unused JS and 153KiB unused CSS, including duplicate Google tag scripts and 98% unused all.min.css. F13 high: Large amounts of unused CSS and JavaScript ship on the landing page. |
be-inclusivenames-roles-labels | issues | high | Image audit found 18 missing alt attributes; Lighthouse failed image-alt and link-name, including the home logo and icon-only links. F14 high: Images and controls lack accessible names. |
be-inclusivesufficient-contrast | issues | high | Lighthouse measured ratios of 2.96:1 and 3.28:1 against yellow/white surfaces, below 4.5:1. F15 high: Primary green links and modal text fail WCAG contrast. |
be-inclusivestructure-and-focus | issues | high | The page has no header/nav/main/footer landmarks, starts sections at h4, contains 16 carousel h1 elements, Lighthouse failed heading-order, and sampled focus outlines are none. F16 high: Heading and landmark structure is illogical, and focus is not visible. |
be-inclusivelegible-text | pass | medium | Representative screenshots and DOM/evaluate inspection found the expected outcome for Text is legible and inclusively rendered: comfortable line layout, precise alignment, stable rendering across mixed fonts, no clipping or cramped wrapping that harms comprehension. |
be-inclusivezoom-reflow-targets-and-media | issues | high | Viewport content includes user-scalable=no; the target probe found many 16px-high links. F17 high: The viewport disables user zoom and target sizing is weak. |
follow-best-practicesno-console-errors | pass | high | Lighthouse errors-in-console audit passed with no items. |
follow-best-practicessound-document-and-assets | issues | high | Image audit found 89 of 100 images missing width/height, 47 missing srcset, nine oversized, and 71 legacy-format assets. F18 medium: Image markup is not dimensioned or responsive. |
follow-best-practicesbrowser-platform-hygiene | pass | high | Lighthouse found no deprecations or BFCache blocker and the page made no on-load permission request. |
be-discoverabletitle-and-description | issues | high | Rendered probes show the Action listing and Login page both titled “VyManga - Read Manga Online For Free | VyManga”; route metadata confirms repetition. F19 medium: Listing, login, and error pages reuse the generic home title/description. |
be-discoverablecrawlable-and-mobile-friendly | issues | high | Lighthouse failed crawlable-anchors for javascript:void(0) links; viewport uses user-scalable=no. F20 medium: Some actions are fake javascript links and the viewport blocks scaling. |
be-discoverablecanonical-and-indexing-signals | issues | high | Platform probe found no canonical link; robots and sitemap exist and return successfully. F21 medium: Pages omit canonical URLs. |
be-discoverablestructured-and-shareable-metadata | issues | high | Home has one JSON-LD block, but route probes and metadata show generic social/title treatment on non-detail templates and no evidenced Manga/Book entity for the inspected detail. F22 medium: Manga detail pages lack entity-specific structured/share metadata. |
be-private-and-securesecure-transport-and-headers | issues | high | Headers primitive found no CSP, HSTS, or nosniff; all five cookies lack Secure, including vyvymanga_session and XSRF-TOKEN. F23 critical: Sensitive cookies are not Secure and baseline security headers are missing. |
be-private-and-securedata-minimisation-and-third-parties | issues | high | HAR reports 49 third-party requests and 4.72MB third-party bytes; tracker scan finds Google Tag Manager and Analytics, with three tag scripts. F24 high: The page loads extensive third-party code and multiple analytics tags. |
be-private-and-securein-context-permissions-and-modern-auth | issues | high | Login DOM contains username/password/captcha fields with no WebAuthn/passkey affordance; no permission prompt calls were found on load. F25 medium: Login is password-only and exposes no phishing-resistant option. |
be-private-and-securedefensive-browser-policies | issues | high | Headers primitive found no HSTS, Referrer-Policy, Permissions-Policy, CSP/frame-ancestors, or nosniff; X-Frame-Options is the sole defense present. F26 high: Browser-enforced defenses are incomplete. |
be-resilientprogressive-enhancement | pass | high | Discoverability comparison found 87% raw-HTML content coverage, title/H1/description present, and no JS shell. |
be-resilientresilient-runtime-behaviour | pass | high | Mobile and desktop screenshots show the active modal within viewport bounds and dismiss controls remain visible. |
be-resilientoffline-and-installable | not-applicable | high | This public content MPA is not presented as an installable application; offline installability is not required for the inspected reading discovery flow. |
be-resilientnetwork-and-http-failure-states | pass | high | The exercised 404 route gives an explanation and a direct Home recovery action. |
be-internationalisedlang-dir-and-logical-properties | issues | high | html lang=en is present, but CSS inspection found zero logical-property rules and no dir declaration. F27 medium: The layout is not prepared for bidirectional/localized presentation. |
be-internationalisedlocale-aware-data | issues | high | Representative pages render values such as “7,640” and “3 hours ago”; no locale alternatives or hreflang were exposed. F28 low: Displayed counts and times are emitted as fixed English strings. |
be-internationalisedtime-zone-correctness | not-applicable | high | The sampled pages expose relative activity labels but no scheduled events, booking, or cross-zone time flow requiring time-zone coordination. |
be-trustworthyno-dark-patterns | issues | high | The detail-page probe resolved START READING to aovheroes.com/rds/... rather than a chapter on vymanga.com. F10 critical: The main “START READING” action points to an unrelated advertising redirect. |
be-trustworthyhumane-error-handling | issues | high | Invalid-form probe reports a native “Please fill in this field” for captcha but no aria-invalid state or accessible announced error summary. F29 medium: Login validation relies on browser bubbles and an unlabeled captcha state. |
be-trustworthytrustworthy-input-assistance | issues | high | Login probe shows blank autocomplete on username and password fields. F30 medium: Authentication inputs omit autocomplete tokens. |
be-trustworthysafe-commercial-and-account-flows | issues | high | Login screenshot shows image arithmetic captcha; DOM exposes password-only authentication and no passkey option. F31 high: The account entry flow uses an inaccessible visual captcha and lacks modern authentication. |
be-sustainableoptimised-assets | issues | high | HAR reports 4.38MB of images; one thumbnail is 1.51MB, 71 images use legacy formats, and 47 lack responsive sources. F32 high: Image delivery is disproportionately heavy and unoptimized. |
be-sustainableno-wasteful-work | issues | high | Three Google tag scripts are loaded; 82 below-fold images lack native lazy loading and Lighthouse finds hundreds of KiB unused code. F33 medium: Redundant analytics and offscreen loading waste network and CPU. |
be-sustainablethird-party-and-media-budget | issues | high | Third parties account for 4.72MB; a decorative Discord GIF is 575KB and analytics scripts exceed 460KB. F34 high: Third-party and decorative media costs dominate the page. |
be-agent-readystructured-agent-capabilities | not-applicable | high | No explicit agent-facing transaction/tool surface was declared; crawler-visible HTML is judged under discoverability instead. |
be-agent-readyon-device-inference | not-applicable | high | No user task on the sampled listing, reading discovery, or login paths requires on-device inference. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | Baseline heap was 23,676,129 bytes/410,724 nodes; after ten carousel-next cycles it was 23,839,171 bytes/413,265 nodes, a small bounded delta across independent captures. |
be-memory-efficientbounded-footprint | pass | high | Heap summary was about 23.7MB with 410,724 snapshot nodes; Performance metrics reported about 10MB used JS heap and 2,862 live DOM elements, proportionate to the content-heavy page. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | Repeated carousel exercise produced only a small snapshot delta; no interval signals were found and there is no evidence of unbounded growth in this bounded test. |
