All 58 atomic check outcomes
| Principle / check | Status | Confidence | Evidence or reason |
|---|---|---|---|
respect-user-preferencesrespects-color-scheme | issues | high | The light/default and prefers-color-scheme: dark captures retain the same black page; the probe reports colorScheme "normal" and no prefers-color-scheme, color-scheme, or light-dark() CSS. F01 medium: The fixed black palette does not follow the user’s light/dark preference. |
respect-user-preferencesrespects-reduced-motion | pass | high | The reduced-motion capture and animation probe found zero running animations; there is no auto-advance or non-essential motion to suppress. |
respect-user-preferencesrespects-contrast | issues | high | Darken affected channel colors or use an accessible foreground token, test every channel palette, and add forced-colors/high-contrast styles that retain control boundaries. F02 high: Lighthouse accessibility found white text on Rai 3 green at 3.77:1, white text on Italia 1 blue at 4.47:1, and the Pagina 2 button at 3.65:1. The stylesheet also has no forced-colors or prefers-contrast adaptation. |
implement-natural-interactionsview-transitions | issues | high | Progressively enhance same-origin page changes with cross-document View Transitions and a no-motion fallback. F03 low: Static MPA links were exercised between four templates; the probe finds no authored view-transition CSS and no cross-document @view-transition rule. |
implement-natural-interactionsscroll-driven-animations | not-applicable | high | No scroll-linked animation or scrollytelling surface exists; the long page is a static listing. |
implement-natural-interactionsphysical-gestures | not-applicable | high | No swipe, drag, carousel, or gesture-driven control exists on the representative templates. |
provide-guided-navigationscroll-state-aware-chrome | issues | high | Keep a compact channel/date navigator available while scrolling and expose position/progress without obscuring content. F04 low: The mobile full-page capture shows a very long sequence of channel cards; CSS inspection found no scroll-state query, sticky shrinking header, or progress indicator, and navigation controls disappear far above the current card. |
provide-guided-navigationanchored-positioning | not-applicable | high | No authored tooltip, popover, or anchored menu was present; the third-party consent surface is modal. |
provide-guided-navigationdirects-attention | issues | high | Keep a compact channel/date navigator available while scrolling and expose position/progress without obscuring content. F04 low: The mobile full-page capture shows a very long sequence of channel cards; CSS inspection found no scroll-state query, sticky shrinking header, or progress indicator, and navigation controls disappear far above the current card. |
maximize-content-reduce-noiseno-intrusive-interruptions | issues | high | Minimise pre-consent collection and present a compact, accessible consent choice with equally direct accept/reject actions; avoid blocking the schedule where consent is not required. F05 high: Desktop, mobile, and channel screenshots show a modal covering the first viewport before interaction, with the page dimmed behind it. |
maximize-content-reduce-noisesemantic-dismissible-primitives | pass | high | The only modal surface is exposed as role=dialog by the consent provider; authored programme disclosures use real links/buttons rather than clickable divs. |
maximize-content-reduce-noisereduced-chrome | issues | high | Collapse unfilled ad slots, reserve only bounded ad space, and simplify repeated icon/navigation chrome around the schedule. F06 medium: The full-page mobile capture contains large blank regions between programme groups and repeated icon grids at both ends; useful schedule content occupies a minority of several viewport-height segments. |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | pass | high | Raw-CDP layout at 360×800 measured scrollWidth=clientWidth=360 and horizontalOverflowPx=0 on home and channel templates; viewport scaling remains allowed to 10×. |
adapt-to-the-form-factorcomponent-level-responsiveness | issues | high | Add container-type to reusable listing regions and use size-aware container queries for card composition, with current media rules as fallback. F07 low: The site stylesheet has three @media blocks but zero @container rules; reused channel cards are laid out by global viewport assumptions. |
adapt-to-the-form-factorinput-modality-aware | issues | high | Give controls at least a 24×24 CSS px target (prefer 44×44 for touch), add spacing around inline links, and define a high-contrast :focus-visible ring. F08 high: The probe measured [continua] links at 56×15 px and programme buttons at 223×21 px; focusing the first navigation link produced outline-style none. |
support-core-task-successclear-purpose-and-primary-action | pass | high | The first content state names today’s TV schedule, date, channels, times, programme titles, and direct links to full channel programming. |
support-core-task-successprimary-flow-completion | pass | high | The representative journey from today’s listing to Rai 1 details and to tomorrow/first-run listings completed through real href links without an account wall. |
support-core-task-successclear-system-state-and-recovery | pass | high | Current date, channel colours/names, LIVE markers, and programme times make the normal loaded state explicit; navigation back to dated listings remains available. |
be-fast-and-stablegood-core-web-vitals | issues | high | Reserve all late content, prioritise the actual LCP element, and delay consent/ad work that competes with primary schedule rendering. F10 high: Lighthouse measured LCP 13.9 s and CLS 0.222; raw-CDP mobile layout measured CLS 0.109 on home and 0.243 on the Rai 1 detail. The trace was fast in a separate warm-like run (LCP 1.15 s), so the slow-path variance itself needs attention. |
be-fast-and-stablevisual-stability | issues | high | Reserve all late content, prioritise the actual LCP element, and delay consent/ad work that competes with primary schedule rendering. F10 high: Lighthouse measured LCP 13.9 s and CLS 0.222; raw-CDP mobile layout measured CLS 0.109 on home and 0.243 on the Rai 1 detail. The trace was fast in a separate warm-like run (LCP 1.15 s), so the slow-path variance itself needs attention. |
be-fast-and-stableefficient-main-thread | pass | high | The raw-CDP trace recorded zero long tasks and 0 ms total blocking time over 9.15 s; Lighthouse corroborated low 90 ms TBT. |
be-fast-and-stableefficient-resource-delivery | issues | high | Reserve all late content, prioritise the actual LCP element, and delay consent/ad work that competes with primary schedule rendering. Load analytics/advertising only after the relevant consent and need, remove duplicate integrations, and conditionally load below-fold media. F10 high: Lighthouse measured LCP 13.9 s and CLS 0.222; raw-CDP mobile layout measured CLS 0.109 on home and 0.243 on the Rai 1 detail. The trace was fast in a separate warm-like run (LCP 1.15 s), so the slow-path variance itself needs attention. F11 medium: HAR recorded 580,101 script bytes out of 774,849 total transferred bytes; Lighthouse estimated 266 KiB of unused JavaScript and 14 KiB of unused CSS. |
be-fast-and-stabletrim-unused-and-duplicate-code | issues | high | Load analytics/advertising only after the relevant consent and need, remove duplicate integrations, and conditionally load below-fold media. F11 medium: HAR recorded 580,101 script bytes out of 774,849 total transferred bytes; Lighthouse estimated 266 KiB of unused JavaScript and 14 KiB of unused CSS. |
be-inclusivenames-roles-labels | issues | high | Add concise programme-title alt text where artwork is meaningful, empty alt for decoration, and descriptive title attributes for every embedded video. F12 high: The image primitive found 8 of 11 images without alt text; the DOM probe found untitled YouTube iframes, and Lighthouse failed the frame-title audit. |
be-inclusivesufficient-contrast | issues | high | Darken affected channel colors or use an accessible foreground token, test every channel palette, and add forced-colors/high-contrast styles that retain control boundaries. F02 high: Lighthouse accessibility found white text on Rai 3 green at 3.77:1, white text on Italia 1 blue at 4.47:1, and the Pagina 2 button at 3.65:1. The stylesheet also has no forced-colors or prefers-contrast adaptation. |
be-inclusivestructure-and-focus | issues | high | Add semantic landmarks and one page H1, keep consent headings within a coherent dialog structure, and make focus order/rings match reading order. F13 high: The probe found no header/nav/main/aside/footer landmarks. On home, consent markup introduced multiple H1s plus hundreds of vendor H2s, while focused navigation had outline-style none. |
be-inclusivelegible-text | issues | high | Increase body/interactive text size and line-height, group times and titles semantically, and use text wrapping and spacing tokens for scanability. F14 medium: The mobile screenshot shows long 14 px schedule lines and 15 px-high continuation links packed into saturated cards, with little line spacing or grouping. |
be-inclusivezoom-reflow-targets-and-media | issues | high | Give controls at least a 24×24 CSS px target (prefer 44×44 for touch), add spacing around inline links, and define a high-contrast :focus-visible ring. Add concise programme-title alt text where artwork is meaningful, empty alt for decoration, and descriptive title attributes for every embedded video. F08 high: The probe measured [continua] links at 56×15 px and programme buttons at 223×21 px; focusing the first navigation link produced outline-style none. F12 high: The image primitive found 8 of 11 images without alt text; the DOM probe found untitled YouTube iframes, and Lighthouse failed the frame-title audit. |
follow-best-practicesno-console-errors | issues | high | Change every same-site asset URL to HTTPS or relative URLs, then resolve the reported inspector and BFCache blockers. F15 medium: Lighthouse captured repeated blocked requests for http://www.staseraintv.com/favicon.ico, reported an inspector issue, and found a BFCache failure. |
follow-best-practicessound-document-and-assets | issues | high | Set intrinsic width/height or aspect-ratio, use responsive srcset/sizes, lazy-load below-fold artwork, and encode suitable assets as WebP/AVIF. F16 medium: The image primitive found 11/11 images without width/height, 9/11 without srcset, 8 below-fold images without lazy loading, and all 11 in legacy PNG/JPEG formats. |
follow-best-practicesbrowser-platform-hygiene | issues | high | Change every same-site asset URL to HTTPS or relative URLs, then resolve the reported inspector and BFCache blockers. F15 medium: Lighthouse captured repeated blocked requests for http://www.staseraintv.com/favicon.ico, reported an inspector issue, and found a BFCache failure. |
be-discoverabletitle-and-description | pass | high | Home and Rai 1 pages have distinct descriptive titles and non-empty Italian meta descriptions in both raw and rendered HTML. |
be-discoverablecrawlable-and-mobile-friendly | pass | high | The probe found real hrefs on essentially all links, a scalable viewport meta, index,follow, and descriptive channel/programme labels. |
be-discoverablecanonical-and-indexing-signals | issues | high | Publish robots.txt and an XML sitemap, add self-referencing canonicals, and keep those signals consistent across today/tomorrow/channel templates. F17 medium: The probe found no canonical URL, while /robots.txt and /sitemap.xml both returned HTTP 404. Public pages otherwise returned 200 and explicitly allowed indexing. |
be-discoverablestructured-and-shareable-metadata | issues | high | Add accurate schema.org BroadcastEvent/TVSeries or ItemList data where appropriate, plus Open Graph title, description, image, and canonical URL. F18 low: Across home and Rai 1 templates the probe found zero JSON-LD blocks and zero Open Graph tags despite visible programme/channel entities. |
be-private-and-securesecure-transport-and-headers | issues | high | Set HSTS, a restrictive CSP including frame-ancestors, nosniff, Referrer-Policy and Permissions-Policy; use HTTPS-only Secure cookies and the least-permissive SameSite value. F19 high: The headers primitive found no CSP, HSTS, nosniff, clickjacking, Referrer-Policy, or Permissions-Policy. All five observed cookies lacked Secure and used SameSite=None; Lighthouse also found an HTTP favicon request. |
be-private-and-securedata-minimisation-and-third-parties | issues | high | Default to no optional tracking, reduce vendors and retention, gate all analytics/ads until consent, and provide a one-click reject choice equal to accept. F20 high: Before any visible consent choice was made, the tracker primitive saw 8 third-party origins and four known tracker hosts; the consent dialog states that 210 partners may process device/personal data, while long-lived analytics/consent cookies last 390–400 days. |
be-private-and-securein-context-permissions-and-modern-auth | not-applicable | high | No authentication flow or browser permission request exists on this public read-only schedule. |
be-private-and-securedefensive-browser-policies | issues | high | Set HSTS, a restrictive CSP including frame-ancestors, nosniff, Referrer-Policy and Permissions-Policy; use HTTPS-only Secure cookies and the least-permissive SameSite value. F19 high: The headers primitive found no CSP, HSTS, nosniff, clickjacking, Referrer-Policy, or Permissions-Policy. All five observed cookies lacked Secure and used SameSite=None; Lighthouse also found an HTTP favicon request. |
be-resilientprogressive-enhancement | pass | high | Discoverability found 81% raw-content coverage on home and 70% on Rai 1, with titles/descriptions and core programme text available without JavaScript; neither page is a JS shell. |
be-resilientresilient-runtime-behaviour | pass | high | Four MPA templates loaded their core content and navigation under fresh sessions; the modal consent surface remained bounded to the viewport and page links stayed usable after reload. |
be-resilientoffline-and-installable | not-applicable | high | This is a public MPA content listing rather than an app; installability/offline operation is not essential to its core task. |
be-resilientnetwork-and-http-failure-states | issues | high | Serve an intentional branded 404/error page with a route back to today’s schedule; distinguish retryable network failures from missing pages. F09 medium: Both /robots.txt and /sitemap.xml returned the default Apache 404 document, which provides no site navigation, search, or route back to the schedule. |
be-internationalisedlang-dir-and-logical-properties | issues | high | Format dates/times with Intl.DateTimeFormat for the declared locale and replace layout-critical left/right properties with inline/block logical equivalents. F21 low: The probe found Italian lang but rendered fixed numeric dates such as 19/07/2026; stylesheet inspection found 29 left/right physical-property uses and no evidence of locale-aware formatting or logical properties. |
be-internationalisedlocale-aware-data | issues | high | Format dates/times with Intl.DateTimeFormat for the declared locale and replace layout-critical left/right properties with inline/block logical equivalents. F21 low: The probe found Italian lang but rendered fixed numeric dates such as 19/07/2026; stylesheet inspection found 29 left/right physical-property uses and no evidence of locale-aware formatting or logical properties. |
be-internationalisedtime-zone-correctness | not-applicable | high | The schedules describe one local Italian broadcast context and expose no cross-zone event coordination flow. |
be-trustworthyno-dark-patterns | issues | high | Default to no optional tracking, reduce vendors and retention, gate all analytics/ads until consent, and provide a one-click reject choice equal to accept. F20 high: Before any visible consent choice was made, the tracker primitive saw 8 third-party origins and four known tracker hosts; the consent dialog states that 210 partners may process device/personal data, while long-lived analytics/consent cookies last 390–400 days. |
be-trustworthyhumane-error-handling | not-applicable | high | No authored form or editable input exists in the representative site templates. |
be-trustworthytrustworthy-input-assistance | not-applicable | high | No authored form or editable input exists in the representative site templates. |
be-trustworthysafe-commercial-and-account-flows | not-applicable | high | No checkout, subscription, authentication, or account-management flow exists. |
be-sustainableoptimised-assets | issues | high | Set intrinsic width/height or aspect-ratio, use responsive srcset/sizes, lazy-load below-fold artwork, and encode suitable assets as WebP/AVIF. F16 medium: The image primitive found 11/11 images without width/height, 9/11 without srcset, 8 below-fold images without lazy loading, and all 11 in legacy PNG/JPEG formats. |
be-sustainableno-wasteful-work | pass | high | The trace recorded no long main-thread tasks and the network capture settled at 40 requests; no continuous autoplay animation or background processing was observed. |
be-sustainablethird-party-and-media-budget | issues | high | Set a route-level byte budget, defer below-fold embeds/images, self-host or trim fonts, and remove or consent-gate low-value third parties. F22 medium: HAR transferred 775 KB across 40 requests, including 580 KB of script; 8 third-party origins loaded and 8 below-fold images were eager, despite the core experience being text schedules and small artwork. |
be-agent-readystructured-agent-capabilities | not-applicable | high | No declared agent-facing intent or transactional capability exists; this public schedule is already largely server-rendered for machine reading. |
be-agent-readyon-device-inference | not-applicable | high | No user task on this simple schedule requires on-device inference. |
be-memory-efficientno-leak-under-repeated-interaction | pass | high | After ten full-page scroll down/up cycles, heap self size was 15.87 MB versus 15.80 MB baseline (+0.43%) and Array count decreased by two, with no unbounded retained-growth signal. |
be-memory-efficientbounded-footprint | pass | high | Heap snapshots measured about 15.8 MB self size and 285k snapshot nodes, proportionate to a page whose large population is mostly the third-party consent UI. |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | high | Neither baseline nor post-scroll heap summaries contained a Detached* constructor; post-scroll constructor populations were essentially unchanged. |
