All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | medium | The dark-emulated screenshot is pixel-identical in palette to the default light capture, and the CSS probe found no prefers-color-scheme, light-dark(), or color-scheme support. F02 medium: The interface ignores the user’s dark color preference. |
respect-user-preferencesrespects-reduced-motion | pass | medium | No active animations were reported under prefers-reduced-motion: reduce, so there is no non-essential motion to suppress. |
respect-user-preferencesrespects-contrast | issues | medium | The prefers-contrast capture is unchanged; the CSS probe found no prefers-contrast/forced-colors rules, while Lighthouse failed color-contrast. F03 medium: High-contrast preferences are not handled and existing contrast fails. |
implement-natural-interactionsview-transitions | issues | medium | The CSS probe found no View Transition rules or API use on a multi-page portal with listing and authentication navigation. F04 low: Route and state changes are abrupt. |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No scroll-linked animation or scrollytelling surface exists on the representative public pages. |
implement-natural-interactionsphysical-gestures | not-applicable | high | No gesture-driven carousel, swipe, pull-to-refresh, or custom pointer interaction was observed. |
provide-guided-navigationscroll-state-aware-chrome | issues | medium | The 2,882 px page has static chrome and no scroll-state query, progress indicator, or responsive scroll cue in the screenshot/CSS probe. F05 low: Long-page navigation chrome does not respond to scroll position. |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip, popover, or edge-positioned menu was exposed in the audited public state. |
provide-guided-navigationdirects-attention | issues | medium | Representative listing/news routes switch or redirect without directional transition, marker, highlight, or focus cue; the CSS probe found none of the corresponding primitives. F06 low: Navigation changes provide weak attention cues. |
maximize-content-reduce-noiseno-intrusive-interruptions | pass | medium | Load captures show no modal interstitial or content-obscuring consent wall; the error toast is small and separately judged for recovery. |
maximize-content-reduce-noisesemantic-dismissible-primitives | issues | medium | The DOM contains hidden drawer controls and custom layer classes, while the platform probe found no dialog, popover, or details element. F07 medium: The custom navigation drawer is not built with a semantic dismissible primitive. |
maximize-content-reduce-noisereduced-chrome | issues | medium | The desktop screenshot stretches list rows and rules across 1,280 px while retaining phone-like chrome; the mobile first viewport is dominated by nav, campaign, and section bars. F08 medium: Dense legacy chrome crowds the content and scales poorly on wide screens. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | pass | medium | At 360×800 the layout reported scrollWidth=clientWidth=360, viewport meta present, and zero horizontal overflow. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | medium | The CSS probe found no @container/container-type rules; the desktop screenshot shows phone-oriented list components stretched full width. F09 medium: Components rely on page-wide sizing rather than container-aware adaptation. |
adapt-to-the-form-factorinput-modality-aware | issues | medium | The focus probe measured registration/login controls at 45×31 px and several elements reported outline-style none; the game navigation is only 38 px high. F10 high: Several primary controls are too small or have no visible custom focus. |
support-core-task-successclear-purpose-and-primary-action | issues | medium | The requested farm-game URL resolves to a generic Mobage portal, so the intended purpose and next action are lost. F01 critical: The requested game URL does not reach the requested service. |
support-core-task-successprimary-flow-completion | issues | medium | The recon probe navigated https://nouen.sp.mbga.jp and finished at https://sp.mbga.jp/, a generic Mobage game/news portal. The farm game journey is therefore unavailable from its public entry URL. F01 critical: The requested game URL does not reach the requested service. |
support-core-task-successclear-system-state-and-recovery | issues | medium | Both mobile and desktop captures display “システムエラーが発生しました。” over the game list, with no retry, details, or support action. F11 high: A generic system error appears without a recovery action. |
be-fast-and-stablegood-core-web-vitals | issues | medium | Lighthouse measured LCP 3.1 s and FCP 2.5 s; the independent trace measured LCP/FCP about 2.82 s. CLS and TBT were good. F12 medium: Largest Contentful Paint misses the good threshold. |
be-fast-and-stablevisual-stability | pass | medium | Layout observation and Lighthouse both reported CLS 0 with no observed shifts. |
be-fast-and-stableefficient-main-thread | pass | medium | Trace and Lighthouse reported no long tasks and 0 ms total blocking time. |
be-fast-and-stableefficient-resource-delivery | issues | medium | HAR recorded 66 requests/1.20 MB, including 1.04 MB of images, parser-blocking CSS/scripts, and many large assets without useful cache headers. F13 medium: Resource delivery is image-heavy and weakly cached. |
be-fast-and-stabletrim-unused-and-duplicate-code | pass | medium | Only about 59 KB of script and 42 KB of CSS transferred; Lighthouse did not report a failing code-hygiene audit. |
be-inclusivenames-roles-labels | issues | medium | The image audit found 44 of 45 img elements without alt; the home form probe also found an unlabeled textarea. F14 high: Accessible names and image alternatives are incomplete. |
be-inclusivesufficient-contrast | issues | medium | Lighthouse’s color-contrast audit failed on the public home page. F15 high: Text contrast fails WCAG minimums. |
be-inclusivestructure-and-focus | issues | medium | Lighthouse found no main landmark; the DOM probe found no semantic landmarks and several focusable items computed outline-style none. F16 high: Landmarks and focus treatment are incomplete. |
be-inclusivelegible-text | pass | medium | Representative screenshots show readable body text without clipping at 360 px; line presentation remains intact despite the separate contrast finding. |
be-inclusivezoom-reflow-targets-and-media | issues | medium | The viewport declares maximum-scale=1 and user-scalable=no; Lighthouse failed meta-viewport and the focus probe measured 31–38 px controls. F17 high: The viewport disables user zoom and some targets are undersized. |
follow-best-practicesno-console-errors | pass | medium | Lighthouse best-practices scored 1.0 with no console-error audit failure. The visible system error is judged under task recovery/resilience. |
follow-best-practicessound-document-and-assets | pass | medium | DOM reports HTML doctype, UTF-8 charset, and the image audit found dimensions on all 45 images and no oversized/aspect-ratio failures. |
follow-best-practicesbrowser-platform-hygiene | pass | medium | Lighthouse best-practices scored 1.0 and no load-time permission prompt, deprecated API failure, or paste prevention was observed. |
be-discoverabletitle-and-description | pass | medium | The rendered and raw page both expose title “モバゲー” and a descriptive meta description. |
be-discoverablecrawlable-and-mobile-friendly | issues | medium | Lighthouse failed crawlable-anchors; recon found multiple links implemented as javascript:void(0) and anchors without href. F18 medium: Some links are not crawlable. |
be-discoverablecanonical-and-indexing-signals | issues | medium | The probe found no canonical or hreflang; sitemap.xml could not be fetched, and the requested nouen host redirects to another host. F19 medium: Canonical and sitemap signals are incomplete. |
be-discoverablestructured-and-shareable-metadata | issues | medium | The page has no JSON-LD and og:description is empty despite representing a game platform; the requested subdomain has no distinct share target. F20 low: Share and entity metadata are incomplete. |
be-private-and-securesecure-transport-and-headers | issues | medium | HTTPS is used, but CSP, HSTS, nosniff and all other inspected policies are absent. All four cookies lack Secure and use SameSite=None. F21 high: Transport defenses and cookie attributes are unsafe. |
be-private-and-securedata-minimisation-and-third-parties | pass | medium | Tracker scan found no known trackers and only two third-party origins; no secret exposure was found. The insecure aborted analytics URL is covered by transport/runtime findings. |
be-private-and-securein-context-permissions-and-modern-auth | issues | medium | The public login offers password and federated providers but no WebAuthn/passkey path; the password field also omits a current-password autocomplete token. F22 medium: Authentication lacks a phishing-resistant passkey option. |
be-private-and-securedefensive-browser-policies | issues | medium | Header evidence shows no clickjacking defense, Referrer-Policy, Permissions-Policy, HSTS, CSP, or origin-isolation signal. F23 high: Defensive browser policies are absent. |
be-resilientprogressive-enhancement | pass | medium | Raw HTML retained 86% of rendered content, including title, H1, and description; the site is not a JS shell. |
be-resilientresilient-runtime-behaviour | issues | medium | The home path renders a system-error toast without recovery while the HAR records an aborted HTTP analytics request. F24 high: Runtime failure handling is not resilient. |
be-resilientoffline-and-installable | not-applicable | high | The public gaming/community portal is intrinsically network-backed; no offline/installable intent is declared, so an offline PWA is not required. |
be-resilientnetwork-and-http-failure-states | issues | medium | The observed system error has no retry/cancel/support action and no explanation of which operation failed. F25 high: Network and HTTP failure states do not provide recovery. |
be-internationalisedlang-dir-and-logical-properties | pass | medium | The Japanese-only surface declares html lang="ja" and uses some logical CSS properties; its left-to-right direction is correctly inherited. |
be-internationalisedlocale-aware-data | not-applicable | high | The audited public surfaces contain no user-facing dates, currencies, durations, or locale-switching requirement to evaluate. |
be-internationalisedtime-zone-correctness | not-applicable | high | No event scheduling or time-zone-sensitive data appears on the representative public surfaces. |
be-trustworthyno-dark-patterns | pass | medium | Public home and login captures show clear Login, cancel, password recovery, first-use, and provider options without confirmshaming or forced consent. |
be-trustworthyhumane-error-handling | issues | medium | After activating Login with empty fields, the screenshot and probe were unchanged; fields were not required/invalid, aria-invalid remained absent, and no role=alert appeared. F26 high: Submitting an empty login form gives no visible or accessible error feedback. |
be-trustworthytrustworthy-input-assistance | issues | medium | Email uses autocomplete="on" and password has no token instead of username and current-password. F27 medium: Login inputs do not expose precise autocomplete semantics. |
be-trustworthysafe-commercial-and-account-flows | pass | medium | The observed account entry clearly exposes cancellation, password recovery, first-use registration, and multiple sign-in alternatives; no purchase commitment was entered. |
be-sustainableoptimised-assets | issues | medium | The image audit found 39 legacy-format images, no modern formats, and 16 below-fold images without lazy loading; HAR attributes 1.04 MB to images. F28 medium: Image assets use legacy formats and eager loading. |
be-sustainableno-wasteful-work | pass | medium | Trace showed no long tasks or ongoing main-thread work, and HAR recorded only one failed XHR rather than chatty background fetching. |
be-sustainablethird-party-and-media-budget | issues | medium | Images account for about 87% of 1.20 MB transferred, including duplicated 181 KB sprites and several 150 KB sprites; 52 requests are from asset/ad subdomains. F29 medium: The page’s visual asset budget is disproportionate to its simple catalog UI. |
be-agent-readystructured-agent-capabilities | not-applicable | high | No developer intent or public agent-facing transactional surface is declared for this legacy portal; absence is treated as an emerging opportunity, not a failure. |
be-agent-readyon-device-inference | not-applicable | high | No summarisation or language-model use case is present on the representative public pages. |
be-memory-efficientno-leak-under-repeated-interaction | pass | medium | After ten full-page scroll cycles, heap self size rose only 22,904 bytes (0.46%) and node count by 134, with stable constructor populations. |
be-memory-efficientbounded-footprint | pass | medium | The public page heap was about 5.0 MB across about 91k snapshot nodes, proportionate to this catalog page. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | medium | The before/after summaries show stable closure/object constructor counts and no Detached* constructor population among leading retained objects. |
