All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | Paired screenshots under default and prefers-color-scheme: dark are visually identical, and the probe found no color-scheme declaration or prefers-color-scheme rule. F01 medium: The main marketplace UI stays light when the user requests dark mode. |
respect-user-preferencesrespects-reduced-motion | issues | high | The reduced-motion probe found no prefers-reduced-motion rule while the image audit found animated GIF assets; the reduced-motion video records the same promotional animation surface. F02 medium: Animated GIF promotions continue without a reduced-motion alternative. |
respect-user-preferencesrespects-contrast | issues | high | The prefers-contrast screenshot does not retint the page; the probe found no prefers-contrast/forced-colors CSS and Lighthouse reported 104 contrast failures on the homepage. F03 high: Many text and control combinations fail contrast, with no high-contrast adaptation. |
implement-natural-interactionsview-transitions | issues | high | DOM/CSS probes across homepage, listing, search, and detail found no view-transition-name, ::view-transition, or @view-transition usage despite frequent browse-to-detail navigation. F04 low: Route changes use abrupt full-document swaps. |
implement-natural-interactionsscroll-driven-animations | pass | medium | CSS/DOM probes found no scroll-linked visual effects and no scroll timeline or animation-timeline; scrolling remained platform-native with low blocking work. |
implement-natural-interactionsphysical-gestures | pass | medium | Mobile screenshots and probes show standard document scrolling and links, with no custom pointer-driven gesture surface fighting browser behavior. |
provide-guided-navigationscroll-state-aware-chrome | issues | medium | The mobile listing is 5,212 CSS pixels tall and the detail page is 11,167 pixels tall, while probes found no scroll-state query or progress/position feedback. F05 low: Long listing pages provide static chrome with no scroll-position feedback. |
provide-guided-navigationanchored-positioning | issues | medium | The rendered interfaces contain header menus and filtering controls, but probes found no anchor-name, position-anchor, or position-try rules. F06 low: Menus and filter overlays do not use CSS anchor positioning. |
provide-guided-navigationdirects-attention | pass | medium | Selected search tabs use a strong underline, filters are visibly labelled, focus outlines are present, and browse/detail transitions preserve clear headings. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | The mobile homepage screenshot shows a fixed YouTube subscribe bar covering content at the bottom with no visible dismiss control. F07 medium: A persistent YouTube promotion consumes the bottom of the mobile viewport. |
maximize-content-reduce-noisesemantic-dismissible-primitives | pass | medium | The search template uses a native dialog and three details disclosures; no blocking modal is present on load. |
maximize-content-reduce-noisereduced-chrome | pass | medium | Aside from the separately reported mobile promo, listing and detail screenshots devote the majority of the viewport to games, art, and task controls rather than decorative app framing. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | pass | medium | All four 360x800 layout captures report horizontalOverflowPx 0 and a viewport meta; screenshots show reflowed cards and controls. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | medium | All four representative probes found no @container/container-type usage, even though cards, filters, and marketplace modules are reused in varied widths. F08 low: Responsive behavior is viewport-only rather than component-aware. |
adapt-to-the-form-factorinput-modality-aware | issues | high | The focus/target probe found 34 of the first 40 homepage targets under 44px in at least one dimension; many links are 17–32px tall, and Lighthouse reported target-size failures. F09 high: Many controls are too small for reliable touch input. |
support-core-task-successclear-purpose-and-primary-action | pass | medium | Home, listing, search, and detail screenshots clearly identify games and expose Browse, Filter, Download Now, or search-result actions. |
support-core-task-successprimary-flow-completion | pass | medium | The audited browse → detail → purchase path reaches a clear free-download/payment-choice page with a prominent “No thanks” route and visible included files. |
support-core-task-successclear-system-state-and-recovery | pass | medium | The invalid route returns HTTP 404 and renders a clear “We couldn’t find your page” message with a recovery link; purchase requirements are visibly labelled. |
be-fast-and-stablegood-core-web-vitals | issues | high | Lighthouse measured 29.9s LCP and 0.284 CLS on the selected game detail page; listing LCP was also 4.2s. F10 high: The representative game detail template has very poor lab LCP and unstable loading. |
be-fast-and-stablevisual-stability | issues | high | The detail image audit found all 7 images missing width/height; Lighthouse measured CLS 0.284 and identified a layout-shift culprit. F11 medium: Game detail media lacks dimensions and shifts during load. |
be-fast-and-stableefficient-main-thread | pass | medium | Trace reports one 91ms long task and 41ms TBT on home; Lighthouse TBT is 50–80ms across representative templates. |
be-fast-and-stableefficient-resource-delivery | issues | high | The HAR identifies main.css and synchronous lib.min.js/index.min.js as parser-inserted high-priority candidates; Lighthouse flags LCP discovery and dependency-tree issues. F12 medium: Parser-blocking assets and weak LCP discovery delay primary content. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | The homepage transfers 793KB; 289KB is script, including 158KB for Google Tag Manager, before a user interacts. F13 medium: Analytics and shared JavaScript consume a disproportionate share of the initial load. |
be-inclusivenames-roles-labels | issues | high | Lighthouse found unnamed buttons, 14 homepage images without alt, 16 unnamed links, and an unnamed SVG; listing/detail templates add dozens more. The probes also found no main landmark. F14 high: Core marketplace cards and controls lack accessible alternatives. |
be-inclusivesufficient-contrast | issues | high | Lighthouse reported 104 contrast failures on home, 51 on listing, and 3 on the creator detail template. F15 high: Text contrast fails widely across the marketplace. |
be-inclusivestructure-and-focus | issues | high | The DOM probes found zero main, nav, header, or footer semantic landmarks on home, listing, search, and detail. Lighthouse fails landmark-one-main on each audited template. F16 medium: Representative pages lack landmark structure. |
be-inclusivelegible-text | pass | medium | Desktop/mobile screenshots show readable line lengths, wrapping, hierarchy, and no horizontal clipping on representative templates. |
be-inclusivezoom-reflow-targets-and-media | issues | high | Lighthouse reports 11 target-size failures on home, 9 on listing, and 112 on detail; probes show many 16–35px-high controls. F17 high: Touch-target sizing prevents a comparable mobile experience. |
follow-best-practicesno-console-errors | pass | medium | Lighthouse best-practices is 1.0 on home/listing and does not report console errors or uncaught exceptions on any audited template. |
follow-best-practicessound-document-and-assets | issues | high | The detail image audit found 7/7 images without dimensions and Lighthouse found 5 images displayed at incorrect aspect ratio. F18 medium: Creator imagery is delivered without dimensions and at incorrect aspect ratios. |
follow-best-practicesbrowser-platform-hygiene | issues | medium | Lighthouse best-practices scored the detail template 0.92 and reported one inspector issue, while home and listing scored 1.0. F19 low: The game detail template logs a browser inspector issue. |
be-discoverabletitle-and-description | pass | medium | Home, listing, and detail have descriptive unique titles and meta descriptions; internal search is deliberately disallowed by robots. |
be-discoverablecrawlable-and-mobile-friendly | pass | medium | All representative pages have viewport meta and real href links; robots allows public templates and explicitly scopes search/checkout exclusions. |
be-discoverablecanonical-and-indexing-signals | issues | high | Homepage and /games probes found no canonical URL, while the purchase page does provide one; robots and sitemap otherwise align and return successful statuses. F20 low: Key indexable marketplace templates omit self-referencing canonicals. |
be-discoverablestructured-and-shareable-metadata | pass | medium | Home has JSON-LD plus Open Graph/Twitter metadata; game detail has two JSON-LD blocks and social metadata matching visible content. |
be-private-and-securesecure-transport-and-headers | issues | high | The headers primitive confirms HTTPS and nosniff/X-Frame-Options, but no Content-Security-Policy or Strict-Transport-Security; analytics cookies are also set without Secure. F21 high: Baseline transport defenses are incomplete. |
be-private-and-securedata-minimisation-and-third-parties | issues | high | Tracker evidence found Google Tag Manager and Google Analytics; two analytics cookies are non-Secure, SameSite=None, and live 400 days. GTM alone transfers 158KB. F22 medium: Analytics loads immediately and creates long-lived identifiers. |
be-private-and-securein-context-permissions-and-modern-auth | blocked | high | The login route consistently returned a Cloudflare “Performing security verification” interstitial instead of the authentication UI. |
be-private-and-securedefensive-browser-policies | issues | high | Headers show no HSTS, CSP, or Permissions-Policy; Referrer-Policy is no-referrer-when-downgrade rather than a stricter modern policy. Clickjacking protection and nosniff are present. F23 medium: Defensive browser policy headers are incomplete or dated. |
be-resilientprogressive-enhancement | pass | medium | Discoverability captures show 100% rendered-content coverage in raw server HTML on home, listing, and detail, with non-JS crawler screenshots retaining content. |
be-resilientresilient-runtime-behaviour | pass | medium | Representative mobile layouts have zero horizontal overflow; native dialog/details are used on search and task content remains available in raw HTML. |
be-resilientoffline-and-installable | not-applicable | medium | The site publishes a standalone manifest but no service worker; this audit treats the public MPA marketplace as an online catalog rather than an intended installable web app. |
be-resilientnetwork-and-http-failure-states | pass | medium | A deliberately invalid route returns a true HTTP 404 and a useful illustrated recovery page with a link back to itch.io. |
be-internationalisedlang-dir-and-logical-properties | issues | high | All pages declare lang=en but no explicit dir; probes found no logical-property rules in accessible styles, while the platform exposes translations and serves global content. F24 medium: The global marketplace does not declare direction or expose logical-layout CSS in audited templates. |
be-internationalisedlocale-aware-data | pass | medium | Rendered templates expose a translation endpoint, locale_en state, localized relative durations, and clear currency symbols rather than ambiguous bare numbers. |
be-internationalisedtime-zone-correctness | pass | medium | Audited public content uses relative durations such as “1 hour ago” rather than ambiguous local absolute timestamps; no scheduling flow was present. |
be-trustworthyno-dark-patterns | pass | medium | The free-game purchase page clearly offers “No thanks, just take me to the downloads,” states the optional suggested payment, and presents terms plainly. |
be-trustworthyhumane-error-handling | pass | medium | Purchase uses native required/email semantics with a visible label and explanatory confirmation text; the 404 state gives a direct recovery action. |
be-trustworthytrustworthy-input-assistance | pass | medium | The purchase email field uses type=email and is visibly labelled; search fields use appropriate text semantics and do not prevent paste. |
be-trustworthysafe-commercial-and-account-flows | pass | medium | The purchase page shows optional contribution, included file sizes, payment methods, terms, and a no-payment route before commitment. |
be-sustainableoptimised-assets | issues | high | Home has 52 below-fold images without lazy loading, 61 without srcset, and animated GIF/JPEG/PNG assets; detail serves a 2500px PNG at 600px and all seven images are legacy formats. F25 medium: Marketplace and creator images are frequently oversized or delivered in legacy formats. |
be-sustainableno-wasteful-work | pass | medium | The home trace has only one long task and 41ms TBT; no autoplay video/media element or repeated background fetch loop was observed. |
be-sustainablethird-party-and-media-budget | issues | high | The homepage transfers 793KB; GTM is the largest single response at 158KB and two GIFs total about 180KB, with analytics active immediately. F26 medium: Third-party analytics and promotional media use substantial resources before interaction. |
be-agent-readystructured-agent-capabilities | not-applicable | high | No WebMCP capability was exposed. |
be-agent-readyon-device-inference | not-applicable | high | No on-device inference surface was present. |
be-memory-efficientno-leak-under-repeated-interaction | pass | medium | After ten full-page scroll cycles, heap self-size rose only 149,319 bytes (1.2%) and node count 1,329 (0.6%), consistent with bounded warm-up rather than unbounded retention. |
be-memory-efficientbounded-footprint | pass | medium | The homepage baseline heap is 12.35MB self-size with 219,473 nodes, proportionate to a dense marketplace page. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | medium | Before/after heap summaries show no Detached* constructor among retained-size leaders and only small bounded growth after repeated scrolling. |
