All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | The dark-emulation screenshot is visually identical to the light capture; computed html color-scheme is normal and the page background remains light. F01 medium: The site does not adapt to the user’s dark colour preference. |
respect-user-preferencesrespects-reduced-motion | pass | high | Reduced-motion emulation was active; document.getAnimations() returned none, so no non-essential motion persisted. |
respect-user-preferencesrespects-contrast | pass | high | Representative screenshots, DOM/runtime probes, Lighthouse, network and interaction evidence directly supported respect-user-preferences/respects-contrast on the audited paths. |
implement-natural-interactionsview-transitions | issues | high | The CSS/runtime probe found no View Transition declarations on the listing/detail journey. F06 low: Primary navigation and state changes use abrupt swaps. |
implement-natural-interactionsscroll-driven-animations | not-applicable | medium | No scroll-linked animation exists on the representative pages, so there is no scroll-animation implementation to judge. |
implement-natural-interactionsphysical-gestures | not-applicable | medium | The audited browse, detail, registration and reader flows expose no gesture-driven control. |
provide-guided-navigationscroll-state-aware-chrome | issues | high | The homepage is about 34,841 CSS px tall on mobile, while screenshots and CSS inspection show static navigation and no progress or scroll-state treatment. F07 low: The very long update feed provides no scroll-aware orientation. |
provide-guided-navigationanchored-positioning | not-applicable | medium | No tooltip, popover or anchored menu was present in the exercised paths. |
provide-guided-navigationdirects-attention | pass | high | The chapter landing provides clearly labelled INICIAR LECTURA and VER CAPÍTULOS actions, preserving orientation between detail and reader. |
maximize-content-reduce-noiseno-intrusive-interruptions | pass | high | Desktop, mobile, detail, registration and reader screenshots show content immediately with no obstructing interstitial. |
maximize-content-reduce-noisesemantic-dismissible-primitives | not-applicable | medium | No overlay or transient rich control appeared in the representative paths. |
maximize-content-reduce-noisereduced-chrome | pass | high | Screenshots show a compact 68 px navigation bar and content-dominant listing/detail layouts. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | pass | high | At 360x800, layout measured scrollWidth 360, clientWidth 360 and zero horizontal overflow on home and reader. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | high | The runtime CSS probe found no @container rules even though cards and update rows appear in multiple column widths. F04 low: Reusable content components only react to global viewport breakpoints. |
adapt-to-the-form-factorinput-modality-aware | issues | high | After programmatically focusing the first control, its computed outline is none; the mobile screenshot confirms the toggle is a primary control. F05 medium: Keyboard focus is not visibly exposed on the navigation toggle. |
support-core-task-successclear-purpose-and-primary-action | pass | high | The first viewport identifies popular Spanish manga and exposes title/chapter links; chapter detail labels the reading action. |
support-core-task-successprimary-flow-completion | pass | high | The exercised home → chapter detail → /manga/leer/725822 journey reached the reading view through real href links. |
support-core-task-successclear-system-state-and-recovery | pass | high | The invalid registration form exposes native required-field messages, and the 404 page gives a clear missing-content explanation and navigation. |
be-fast-and-stablegood-core-web-vitals | issues | high | Lighthouse measured LCP at 11.0 s and FCP at 3.4 s; the trace corroborated LCP at 3.34 s under a different run, showing material run-to-run network sensitivity. F08 high: Largest Contentful Paint is far outside the good range. |
be-fast-and-stablevisual-stability | pass | high | Mobile home CLS was 0.00048 and reader CLS 0.0409, both within the good range. |
be-fast-and-stableefficient-main-thread | pass | high | Trace found one 61 ms long task and only 11 ms total blocking time. |
be-fast-and-stableefficient-resource-delivery | issues | high | HAR recorded 634 requests and 12,928,452 transferred bytes, including 602 image requests and 12,195,824 image bytes; Lighthouse estimates 8,318 KiB cache and 3,255 KiB image-delivery savings. F09 high: The homepage transfers an excessive number and weight of image resources. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | Lighthouse estimates 241 KiB unused JavaScript and 61 KiB unused CSS; the DOM lists jQuery, jQuery UI, Bootstrap and multiple plugins loaded globally. F10 medium: The page ships avoidable legacy and unused CSS/JavaScript. |
be-inclusivenames-roles-labels | pass | high | Images have alt text, registration inputs have associated labels, and Lighthouse did not flag name/role/label failures. |
be-inclusivesufficient-contrast | issues | high | Lighthouse reports the section heading at 3.86:1, Popular badges at 3.68:1, and inline links at 1.51:1 against surrounding text. F02 high: Text and link treatments fail minimum contrast requirements. |
be-inclusivestructure-and-focus | issues | high | Lighthouse finds skipped heading levels and no main landmark; the focused mobile navigation button computes outline: none. F03 medium: Semantic structure and keyboard focus are incomplete. |
be-inclusivelegible-text | pass | high | Screenshots show readable 16 px body copy and stable wrapping across desktop/mobile, apart from separately reported contrast. |
be-inclusivezoom-reflow-targets-and-media | pass | high | Viewport permits scaling; 360 px captures reflow without horizontal overflow, and sampled primary targets are generously sized. |
follow-best-practicesno-console-errors | pass | high | Lighthouse completed without an errors-in-console failure or uncaught-exception audit failure. |
follow-best-practicessound-document-and-assets | issues | high | Lighthouse and the images primitive find the logo and all 21 sampled images without explicit width/height; html lacks lang and the page has no main landmark. F11 medium: Document semantics and image dimensions are incomplete. |
follow-best-practicesbrowser-platform-hygiene | issues | high | Lighthouse reports five BFCache failure reasons, including Cache-Control: no-store and WebSocket use, plus DevTools cookie issues. F12 medium: Caching and browser-platform hygiene prevent fast return navigation. |
be-discoverabletitle-and-description | pass | high | DOM recon found a descriptive title and Spanish meta description. |
be-discoverablecrawlable-and-mobile-friendly | pass | high | Links use real href values, viewport metadata is present, robots.txt permits public content, and the no-JS crawler screenshot renders the page. |
be-discoverablecanonical-and-indexing-signals | issues | high | The live DOM has no canonical URL, /sitemap.xml returns 404, and raw fetch/discoverability encountered a repeated Cloudflare redirect while the no-JS browser view itself remained readable. F13 medium: Indexing signals are incomplete and crawler requests encounter redirect friction. |
be-discoverablestructured-and-shareable-metadata | pass | high | Homepage Open Graph metadata includes URL, type, title, description, image, locale and site name, matching visible content. |
be-private-and-securesecure-transport-and-headers | issues | high | HTTPS is used, but headers found no CSP, HSTS or nosniff; PHPSESSID is neither Secure nor HttpOnly and all eight observed cookies use SameSite=None. F14 high: Transport and session-cookie protections are incomplete. |
be-private-and-securedata-minimisation-and-third-parties | issues | high | The trackers primitive found Google Analytics and Yandex Metrika, eight third-party origins, and Yandex cookie-sync traffic; Lighthouse recorded 18 third-party cookies. F15 high: Tracking runs immediately with a broad cookie and request footprint. |
be-private-and-securein-context-permissions-and-modern-auth | not-applicable | medium | No permission prompt fired, and authentication implementation beyond the public registration surface was not part of the unauthenticated core journey. |
be-private-and-securedefensive-browser-policies | issues | high | Headers show X-Frame-Options: SAMEORIGIN, but no Referrer-Policy, Permissions-Policy, CSP frame-ancestors or HSTS. F16 medium: Several browser-enforced defence policies are absent. |
be-resilientprogressive-enhancement | pass | high | The crawler screenshot with JavaScript disabled renders the same core manga titles and links as the browser view. |
be-resilientresilient-runtime-behaviour | pass | high | Navigation, registration and reader screenshots loaded usable stable states; the mobile menu survived ten open/close cycles. |
be-resilientoffline-and-installable | not-applicable | medium | This is a content website rather than an app-like experience; installability/offline application behavior is contextual here. |
be-resilientnetwork-and-http-failure-states | pass | high | A deliberately invalid path renders a clear Spanish 404 explanation and retains site navigation. |
be-internationalisedlang-dir-and-logical-properties | issues | high | The rendered DOM has html lang="" and Lighthouse fails html-has-lang, despite Spanish content and metadata. F17 medium: The Spanish document does not declare its language. |
be-internationalisedlocale-aware-data | pass | high | Visible dates and relative times are presented in familiar Spanish forms; no currency or numeric locale flow is present. |
be-internationalisedtime-zone-correctness | not-applicable | medium | The sampled public content exposes upload dates but no cross-time-zone scheduling or event coordination. |
be-trustworthyno-dark-patterns | pass | high | Representative screenshots show direct browsing/reading and registration choices without forced continuity, consent nagging or disguised actions. |
be-trustworthyhumane-error-handling | pass | high | Required registration fields use native constraint validation with field-specific fill-in messages after validity checking. |
be-trustworthytrustworthy-input-assistance | issues | high | All email, username and password fields return an empty autocomplete property, including the repeated password field. F18 medium: The registration form omits autocomplete assistance. |
be-trustworthysafe-commercial-and-account-flows | not-applicable | medium | No checkout, subscription, payment or authenticated account-management flow is present in the public core reading journey. |
be-sustainableoptimised-assets | issues | high | HAR transferred 12.2 MB across 602 image requests; the image probe found no modern-format sampled images, 20 below-fold images without native lazy loading and missing responsive sources. F19 high: The image-heavy feed is not delivered within a proportionate resource budget. |
be-sustainableno-wasteful-work | pass | high | Trace shows only 11 ms blocking time and no sustained animation; the principal waste is network/media and is reported separately. |
be-sustainablethird-party-and-media-budget | issues | high | Eight third-party origins and active analytics accompany a 12.9 MB, 634-request load before user interaction. F20 medium: Third-party and background resource use is disproportionate for a content index. |
be-agent-readystructured-agent-capabilities | not-applicable | medium | No declared intent suggests agent-facing transactional capabilities; this emerging check is contextual and not applicable. |
be-agent-readyon-device-inference | not-applicable | medium | The content browsing and reading experience has no inference task where built-in AI would clearly improve the core journey. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | After ten mobile-menu open/close cycles, heap nodes fell from 301,648 to 293,395 and self size fell from 18,547,872 to 18,020,481 bytes. |
be-memory-efficientbounded-footprint | pass | high | Heap summary measured 18.5 MB self size and 301,648 nodes for the large content index, proportionate to its rendered feed. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | The repeated-interaction heap did not grow in node or edge count, providing no evidence of accumulating detached DOM/listeners in the tested cycle. |
