All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | With prefers-color-scheme: dark active, the computed probe reported color-scheme: normal, body background rgb(251,251,253), and text rgb(44,44,44), the same light palette. F1 medium: The site does not adapt its main surfaces to the user’s dark color-scheme preference. |
respect-user-preferencesrespects-reduced-motion | pass | medium | Reduced-motion emulation was active and the deep animation probe found zero running animations. |
respect-user-preferencesrespects-contrast | pass | medium | Forced-colors capture preserved the top navigation and controls; Lighthouse contrast checks did not fail. |
implement-natural-interactionsview-transitions | pass | medium | The deep style probe found elements with non-none view-transition names and no blocking main-thread animation. |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No scroll-linked decorative animation is part of the tested core experience. |
implement-natural-interactionsphysical-gestures | pass | medium | Mobile captures use native scrolling with no horizontal overflow; no custom pointer-drag dependency blocked navigation. |
provide-guided-navigationscroll-state-aware-chrome | pass | medium | Homepage navigation remains compact while content scrolls and the tested scrolling produced no long tasks. |
provide-guided-navigationanchored-positioning | not-applicable | high | No tooltip, contextual popover, or anchored overlay was encountered on the representative paths. |

maximize-content-reduce-noiseno-intrusive-interruptions | pass | medium | No interstitial or unsolicited modal obscured any tested first viewport. |
maximize-content-reduce-noisesemantic-dismissible-primitives | pass | medium | No blocking custom modal appeared; menus and native media controls remained dismissible/navigable in the tested states. |
maximize-content-reduce-noisereduced-chrome | pass | medium | The first view prioritizes Wayback search/library content; item view gives most space to media and metadata. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | pass | medium | All four mobile layout captures reported horizontalOverflowPx: 0 at 360px. |
adapt-to-the-form-factorcomponent-level-responsiveness | pass | medium | At 360px, tested templates fit the viewport with no horizontal overflow and the item content stacks vertically. |
adapt-to-the-form-factorinput-modality-aware | issues | high | The focus probe programmatically focused the first 30 controls; Wayback Machine, Texts, Video, Audio, Software, Images and several menu links computed outline-style:none, while Sign up and Log in had 0px outlines. F2 high: Keyboard focus is invisible on many primary navigation links. |
support-core-task-successclear-purpose-and-primary-action | pass | medium | Homepage and signup screenshots state the service purpose and present clear search/signup actions. |
support-core-task-successprimary-flow-completion | issues | high | After 8 seconds the Movies listing remained on an unlabeled spinner, search for “public domain” showed 0 results, and the item player displayed “failed to load (Error Code: 101104)” with no retry action. F3 high: Primary browse, search, and playback journeys can stall or fail without useful recovery. |
support-core-task-successclear-system-state-and-recovery | issues | high | After 8 seconds the Movies listing remained on an unlabeled spinner, search for “public domain” showed 0 results, and the item player displayed “failed to load (Error Code: 101104)” with no retry action.

be-inclusivenames-roles-labels | issues | high | Lighthouse reported heading-order failures and label-content-name-mismatch on collection tile links, where aria-label did not include the full visible text. F5 medium: Homepage collection tiles and heading structure expose accessibility defects. |
be-inclusivesufficient-contrast | pass | medium | Lighthouse accessibility scores were 0.99 and 0.96 and no contrast failure was reported; forced-colors capture remained legible. |
be-inclusivestructure-and-focus | issues | high | The focus probe programmatically focused the first 30 controls; Wayback Machine, Texts, Video, Audio, Software, Images and several menu links computed outline-style:none, while Sign up and Log in had 0px outlines.

HSTS was present. F8 high: Defensive browser policies leave avoidable XSS, MIME-sniffing, framing, and feature-control exposure. |
be-private-and-securedata-minimisation-and-third-parties | pass | medium | Tracker probe found zero known trackers/third-party origins; HAR attributed 0 transferred bytes to the only nominal third-party origin. |
be-private-and-securein-context-permissions-and-modern-auth | pass | medium | No permission prompts or allow-bearing iframes appeared on load; signup offers established Google and email-code paths. |

be-resilientprogressive-enhancement | issues | high | Raw homepage/listing HTML is a bare <app-root> plus a “Javascript is required” message. Discoverability found only 33% shared words, no raw H1, and crawler screenshots contain no library content; the item template, by contrast, reached 96%. F7 medium: Homepage and listing content is effectively unavailable without JavaScript. |
be-resilientresilient-runtime-behaviour | pass | medium | The 404 endpoint returns a real 404 and tested responsive layouts remained stable; no viewport-edge overlay failure was encountered. |
be-resilientoffline-and-installable | not-applicable | high | Archive.org is a network-dependent public digital library and exposes no install intent; offline/installability is contextual here. |
be-resilientnetwork-and-http-failure-states | issues | high | After 8 seconds the Movies listing remained on an unlabeled spinner, search for “public domain” showed 0 results, and the item player displayed “failed to load (Error Code: 101104)” with no retry action. F3 high: Primary browse, search, and playback journeys can stall or fail without useful recovery. |
be-internationalisedlang-dir-and-logical-properties | issues | medium | The item showed ISO date 2009-12-09 and comma-grouped 457,169; stylesheet inspection found 395 physical left properties versus 6 logical inline properties, despite a global public audience. F9 medium: Internationalisation support is partial and the tested item renders locale-sensitive data in fixed formats. |
be-internationalisedlocale-aware-data | issues | medium | The item showed ISO date 2009-12-09 and comma-grouped 457,169; stylesheet inspection found 395 physical left properties versus 6 logical inline properties, despite a global public audience. F9 medium: Internationalisation support is partial and the tested item renders locale-sensitive data in fixed formats. |
be-internationalisedtime-zone-correctness | not-applicable | high | The representative public paths expose archival dates but no scheduling or cross-time-zone event workflow. |
be-trustworthyno-dark-patterns | pass | medium | Signup clearly offers Google, email-code and email/password options with a visible log-in alternative; no forced consent or preselected marketing was visible. |
be-trustworthyhumane-error-handling | pass | medium | Submitting empty signup fields invoked native, field-specific “Please fill in this field” messages for email, screen name and password. |
be-trustworthytrustworthy-input-assistance | issues | high | The signup probe found email and screen-name inputs with empty autocomplete values, and the new account password field used autocomplete=current-password instead of new-password. F10 medium: Signup fields omit or misuse autofill purpose tokens. |
be-trustworthysafe-commercial-and-account-flows | issues | high | The signup probe found email and screen-name inputs with empty autocomplete values, and the new account password field used autocomplete=current-password instead of new-password. F10 medium: Signup fields omit or misuse autofill purpose tokens. |
be-sustainableoptimised-assets | issues | high | Lighthouse’s LCP discovery insight reported priorityHinted:false for the video preview image; resource-load delay was 15.81s. F11 medium: The representative item’s LCP preview is not prioritized as a critical asset. |

be-sustainablethird-party-and-media-budget | pass | medium | HAR showed 309KB transferred and no third-party byte payload; no autoplaying media was observed on load. |
be-agent-readystructured-agent-capabilities | issues | high | Raw homepage/listing HTML is a bare <app-root> plus a “Javascript is required” message. Discoverability found only 33% shared words, no raw H1, and crawler screenshots contain no library content; the item template, by contrast, reached 96%. F7 medium: Homepage and listing content is effectively unavailable without JavaScript. |
be-agent-readyon-device-inference | not-applicable | high | No page task requires on-device summarisation or language-model inference; this contextual capability is not part of the observed product intent. |
be-memory-efficientno-leak-under-repeated-interaction | issues | medium | Baseline heap summary was 126,348 nodes / 7.36 MB self size; after ten bottom/top scroll cycles it was 166,653 nodes / 10.91 MB, a 32% node and 48% size increase. No Detached* constructor appeared, so the source of retention is not established. F12 medium: Heap retention grew substantially after repeated homepage scrolling. |
be-memory-efficientbounded-footprint | issues | medium | Baseline heap summary was 126,348 nodes / 7.36 MB self size; after ten bottom/top scroll cycles it was 166,653 nodes / 10.91 MB, a 32% node and 48% size increase.
