maximize-content-reduce-noisesemantic-dismissible-primitives | issues | high | 0 native dialogs/popovers and 2 custom role=dialog overlays. F03 medium: Consent overlays use custom role=dialog containers rather than native dialog |
maximize-content-reduce-noisereduced-chrome | issues | high | Mobile match view is dominated by ad cards, navigation, and consent before match content. F04 high: Advertising and chrome crowd the core match task on mobile |
adapt-to-the-form-factorresponsive-no-horizontal-scroll | pass | high | Home, match, and article at 360px report scrollWidth=clientWidth=360 and no overflow; viewport meta exists. |

support-core-task-successclear-system-state-and-recovery | pass | medium | Live/scheduled match states are visible and the invalid route returns a readable error with a Diretta.it recovery link. |
be-fast-and-stablegood-core-web-vitals | issues | high | Lighthouse LCP 14.5s, CLS 0.32 and TBT 900ms. F05 critical: Mobile load performance is far outside good Core Web Vitals |

follow-best-practicessound-document-and-assets | issues | high | Doctype/UTF-8 pass, but one image has wrong aspect ratio and all sampled images lack intrinsic dimensions. F11 medium: Document assets include unsized and incorrectly proportioned images |
follow-best-practicesbrowser-platform-hygiene | issues | high | Lighthouse found a BFCache blocker and two missing source maps. F13 medium: Platform hygiene prevents BFCache and omits source maps |

be-private-and-securedefensive-browser-policies | issues | high | HSTS, frame protection, Referrer-Policy, Permissions-Policy and CSP are absent. F19 high: Browser-enforced security policies are not configured |

be-internationalisedtime-zone-correctness | pass | low | Match detail presents an unambiguous full local date and time for the Italian locale rather than a partial timestamp. |
be-trustworthyno-dark-patterns | issues | high | Full consent wall and 1001-partner scope precede core content, although reject remains equally prominent. F21 high: The consent experience is a nagging wall with extreme vendor scope |

be-trustworthytrustworthy-input-assistance | not-applicable | high | No input fields are present in the representative public paths. |
be-trustworthysafe-commercial-and-account-flows | issues | high | Consent is a relevant commercial/privacy flow and blocks the task with exceptionally broad vendor scope. F21 high: The consent experience is a nagging wall with extreme vendor scope |
be-sustainableoptimised-assets | issues | high | 100 legacy-format images, 100 missing dimensions, four missing srcset, zero modern formats. F22 medium: Images use legacy formats without responsive delivery metadata |
be-sustainableno-wasteful-work | issues | high | 109 requests/42 scripts, 900ms TBT, and many persistent reduced-motion animations indicate avoidable work. F24 medium: Background and startup work is not proportionate |

be-agent-readyon-device-inference | not-applicable | high | No declared or visible agent-facing workflow was found. |
be-memory-efficientno-leak-under-repeated-interaction | issues | low | Post-interaction snapshot is +30.0MB and +455,288 nodes versus baseline; separate sessions make this a low-confidence leak signal. F26 high: Heap grows substantially after repeated consent interaction |
be-memory-efficientbounded-footprint | issues | high | Baseline is 62.5MB self size with 937,483 nodes and 4.31M edges. F25 high: The initial memory footprint is unusually large for a score listing |
be-memory-efficientno-detached-dom-or-unbounded-listeners | pass | medium | No Detached* constructor appears among top constructors and EventItemImpl remains exactly 284 before/after; no direct accumulation signal was found. |
