Coverage complete
Coverage complete: all 58 catalog checks have conclusive outcomes. Representative coverage includes home, listing, detail, reader, search, login, registration, and recovery; checkout/payment completion, post-auth account management, adult surfaces, community, and every genre template were not covered because they require credentials/commitment or duplicate the sampled catalog templates.

All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | The dark-condition screenshot is visually identical to the light surface, and the CSS probe reports color-scheme: normal with a white body. F01 medium: The public catalog is light-only. |
respect-user-preferencesrespects-reduced-motion | pass | high | Under prefers-reduced-motion: reduce the page reports zero active animations and scroll-behavior auto. |
respect-user-preferencesrespects-contrast | issues | high | Lighthouse failed color-contrast, while the contrast-preference screenshot remains unchanged from default. F16 high: Text and controls fail minimum contrast. |
implement-natural-interactionsview-transitions | issues | high | DOM/CSS inspection found no authored view-transition rules; representative page changes are full abrupt swaps. F02 low: Navigation and content changes do not use authored view transitions. |
implement-natural-interactionsscroll-driven-animations | pass | high | DOM/CSS and runtime probes found no scroll-linked animation or scroll event-driven visual effect, so there is no main-thread scroll animation anti-pattern. |
implement-natural-interactionsphysical-gestures | pass | high | Representative catalog, detail, search, and reader paths use native scrolling/click activation and showed no custom pointer gesture that fights platform behavior. |
provide-guided-navigationscroll-state-aware-chrome | issues | high | The homepage is over 11,000 CSS px tall, while DOM/CSS inspection found no scroll-state container query or progress treatment. F03 low: Long pages provide static chrome with no scroll-position feedback. |
provide-guided-navigationanchored-positioning | issues | high | CSS places sideRightMenu absolutely at top:69px/right:14px and the account menu at fixed offsets; no anchor-name/position-anchor/position-try was found. F04 low: Header menus are manually positioned rather than anchored. |
provide-guided-navigationdirects-attention | pass | high | Breadcrumbs, explicit section headings, descriptive links, and highlighted genre tabs preserve location and next-step context. |
maximize-content-reduce-noiseno-intrusive-interruptions | pass | high | Fresh-load screenshots across home, listing, detail and auth show no content-blocking modal or full-viewport interstitial. |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | The probe found zero dialog, popover, or details elements while DOM CSS shows class-toggled custom menu overlays and close controls. F05 medium: Custom div menus replace semantic dismissible primitives. |
maximize-content-reduce-noisereduced-chrome | issues | high | The first mobile-scaled viewport contains multiple navigation bars, a safety-search block, sidebar calls to action, and several stacked campaign banners before/alongside core books. F06 high: Dense promotional chrome crowds the actual catalog. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | issues | high | At a 360x800 emulation, layout metrics report clientWidth/innerWidth 1024 because the viewport is width=1024; screenshots show tiny desktop text and controls. F07 critical: Mobile receives a 1024px desktop layout scaled down to fit. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | high | The probe found zero container rules; authored CSS repeatedly fixes the main shell and common regions at 990px. F08 medium: Reusable catalog components do not adapt at component level. |
adapt-to-the-form-factorinput-modality-aware | issues | high | The probe counted 120 visible targets below 24px in one dimension, Lighthouse failed target-size, and the scaled mobile shell makes controls materially smaller. F09 high: Many controls are too small for touch. |
support-core-task-successclear-purpose-and-primary-action | pass | high | Homepage, listing and detail clearly identify comics and expose search, free reading, sample, registration and purchase actions. |
support-core-task-successprimary-flow-completion | pass | high | The catalog-to-detail-to-free-reader journey completed; the reader redirected to a populated speedreader page with the correct title. |
support-core-task-successclear-system-state-and-recovery | pass | high | A deliberately missing route renders a detailed error state with back/retry advice and links to search, rankings, free content, help and top. |
be-fast-and-stablegood-core-web-vitals | issues | high | Mobile Lighthouse measured LCP 16.3s, CLS 0.662, TBT 230ms and performance 0.33; an unconstrained desktop trace was faster (LCP 1.41s), showing the mobile/throttled risk. F10 critical: Lab Core Web Vitals are poor. |
be-fast-and-stablevisual-stability | issues | high | Lighthouse reported CLS 0.662 and two layout shifts; the image audit found 31 homepage images without dimensions. F11 high: Late content causes major layout shift under mobile lab conditions. |
be-fast-and-stableefficient-main-thread | issues | high | Lighthouse reported 2.6s main-thread work and 1.3s JavaScript execution; the page loads 58 scripts. F12 high: JavaScript startup is heavy. |
be-fast-and-stableefficient-resource-delivery | issues | high | HAR confirms parser-inserted blocking jQuery, Axios and cookie scripts plus five stylesheets; Lighthouse estimates 1.03s render-blocking and 2,209KiB cache savings. F13 high: The critical path and caching are inefficient. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | Lighthouse estimates 862KiB unused JavaScript and 13KiB unused CSS; DOM inspection shows duplicate Axios, jquery.cookie, Yahoo and LINE/TikTok loaders. F14 high: The page ships substantial unused and duplicate client code. |
be-inclusivenames-roles-labels | issues | high | Lighthouse fails image-alt, input-image-alt and link-name; search inspection found unlabeled text/select fields, and the detail image audit found 74 images without alt. F15 high: Forms, links, and images have incomplete accessible names. |
be-inclusivesufficient-contrast | issues | high | Lighthouse failed color-contrast, while the contrast-preference screenshot remains unchanged from default. F16 high: Text and controls fail minimum contrast. |
be-inclusivestructure-and-focus | issues | high | Lighthouse reports non-sequential headings and no main landmark; the page jumps from H2/H3 to H4 and uses many role-bearing fragments without a main region. F17 high: Document structure is incomplete for assistive navigation. |
be-inclusivelegible-text | issues | high | The 360px screenshots render a 1024px canvas at 0.3516 scale, reducing already-small 9px to 13px labels to a few physical pixels. F18 high: The scaled desktop layout makes text illegible on phones. |
be-inclusivezoom-reflow-targets-and-media | issues | high | Homepage uses width=1024; the login viewport includes maximum-scale=1 and user-scalable=0; Lighthouse fails meta-viewport and target-size. F19 high: Viewport policy and fixed layout obstruct zoom and reflow. |
follow-best-practicesno-console-errors | issues | high | Lighthouse explicitly failed errors-in-console; HAR also records blocked/aborted marketing requests. F20 medium: The homepage logs browser errors. |
follow-best-practicessound-document-and-assets | issues | high | The image audit found 31 homepage and 42 detail images missing dimensions; Lighthouse also failed unsized-images. F21 medium: Image dimensions and asset structure are inconsistent. |
follow-best-practicesbrowser-platform-hygiene | issues | high | Lighthouse failed inspector-issues and BFCache with three failure reasons; the page also loads many legacy scripts and duplicated integrations. F22 medium: Chrome reports platform hygiene problems. |
be-discoverabletitle-and-description | pass | high | Homepage and product have unique descriptive titles and meta descriptions in raw and rendered HTML. |
be-discoverablecrawlable-and-mobile-friendly | issues | high | Lighthouse failed crawlable-anchors. This coexists with 100% raw-content coverage and hundreds of valid href links, so the defect is limited rather than a JS-shell failure. F23 medium: Some links are not crawlable despite strong server rendering. |
be-discoverablecanonical-and-indexing-signals | pass | high | Both tested public pages returned 200, expose matching canonicals, and are present in server-rendered HTML without accidental noindex. |
be-discoverablestructured-and-shareable-metadata | pass | high | Product includes Product, Book and Breadcrumb JSON-LD plus matching Open Graph title, description, URL and image. |
be-private-and-securesecure-transport-and-headers | issues | high | HTTPS and frame-ancestors are present, but HSTS and nosniff are missing; 27 of 29 cookies lack Secure and many use SameSite=None. F24 high: Transport policy and cookie attributes are weak. |
be-private-and-securedata-minimisation-and-third-parties | issues | high | The tracker capture sees 42 third-party origins and Google, Facebook, DoubleClick, TikTok, Twitter, LINE, Yahoo and others; HAR records 328 third-party requests and about 5.09MB transferred. F25 high: Tracking and third-party collection are excessive on first load. |
be-private-and-securein-context-permissions-and-modern-auth | issues | high | The login screenshot exposes email/password and six social identity choices; inspected auth markup contains no WebAuthn/passkey signal. No permission prompt fired on load. F26 medium: Authentication offers password and federated identity but no phishing-resistant passkey path. |
be-private-and-securedefensive-browser-policies | issues | high | Headers lack HSTS, Referrer-Policy and nosniff; Permissions-Policy only grants client-hint features and CSP only sets frame-ancestors. F27 high: Browser-enforced defenses are incomplete. |
be-resilientprogressive-enhancement | pass | high | Discoverability measured 100% homepage and 95% product content coverage without JavaScript; core content is server-rendered. |
be-resilientresilient-runtime-behaviour | issues | high | Header dropdowns are class-toggled absolute boxes with fixed widths/offsets and no anchor fallback; the main site is fixed at 990px. F28 medium: Custom fixed-offset overlays are fragile at viewport edges. |
be-resilientoffline-and-installable | not-applicable | high | This is a public commerce/content site rather than an installed app; an offline catalog/reader was not an evidenced product requirement. |
be-resilientnetwork-and-http-failure-states | pass | high | The deliberately missing route presents a content-rich recovery screen with actionable destination links rather than a blank shell. |
be-internationalisedlang-dir-and-logical-properties | pass | high | The Japanese pages consistently set html lang=ja and render in the expected LTR reading direction; no alternate locale was declared. |
be-internationalisedlocale-aware-data | not-applicable | high | The representative Japanese pages expose no user-entered or dynamic locale-sensitive date, number, currency, duration, or calendar workflow to test. |
be-internationalisedtime-zone-correctness | not-applicable | high | No events, schedules, or user-facing time-zone-sensitive values occur in the representative paths. |
be-trustworthyno-dark-patterns | pass | high | The sampled pages show explicit free, sale, login and registration actions without confirmshaming, forced continuity, or a blocking consent wall. |
be-trustworthyhumane-error-handling | pass | high | The tested site error state explains likely causes and offers concrete recovery routes in neutral language. |
be-trustworthytrustworthy-input-assistance | issues | high | Search fields have empty autocomplete and no programmatic labels; homepage search explicitly disables autocomplete. F29 medium: Search and sign-in input assistance is incomplete. |
be-trustworthysafe-commercial-and-account-flows | pass | high | Product pricing/free status and login/registration choices are visibly separated; the audit did not trigger a purchase or observe hidden continuity. |
be-sustainableoptimised-assets | issues | high | Of 100 homepage images, 99 use legacy formats, 35 are oversized, 53 lack srcset and 70 below-fold images are not lazy; images transfer 3.31MB. F30 high: Image delivery is wasteful. |
be-sustainableno-wasteful-work | issues | high | The load makes 330 requests and runs repeated vendor loaders, with Lighthouse estimating 862KiB unused JavaScript. F31 high: Background marketing work dominates a page view. |
be-sustainablethird-party-and-media-budget | issues | high | Tag Manager/gtag transfer more than 500KB, TikTok variants over 300KB, Facebook 175KB, amid 42 third-party origins; total load is 5.13MB. F32 high: Third-party script cost is disproportionate to visible user value. |
be-agent-readystructured-agent-capabilities | not-applicable | high | No declared agent-facing intent was available; the emerging WebMCP capability is treated as an opportunity, not a requirement. |
be-agent-readyon-device-inference | not-applicable | high | No summarisation or language-model feature is part of the observed product intent, so on-device inference is not required. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | After ten real safe-search state changes, the post heap was smaller than baseline (340,766 vs 497,714 nodes; 18.3MB vs 28.9MB self size), with no retained-growth signal. |
be-memory-efficientbounded-footprint | pass | high | Heap snapshots measured a bounded 18.3MB to 28.9MB self-size range for this image-heavy catalog; no monotonic growth was observed. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | medium | The repeated interaction did not increase total heap/node population; this provides no evidence of accumulating detached DOM/listeners, though constructor-level confidence is medium. |
