31{"item_id":"fi-0001","verdict":"drop","alt_quality":"weak","reason":"Functional: the logo links to the site root. But the alt is the bare brand name, and the destination is what a person needs announced. \"ThriftBooks home\" would be good; \"ThriftBooks\" is weak.","subtype":null}
{"item_id":"fi-1590","verdict":"drop","alt_quality":"weak","reason":"Functional: the SVG wordmark links to the site root, so the sub-type is a linked logo rather than a navigational link. The SVG title is the bare brand name and does not say where the link goes.","subtype":"linked-standalone-logo"}
{"item_id":"fi-1802","verdict":"keep","alt_quality":"good","reason":"Functional: an icon-only reset button in a form. The button's aria-label names the action, not the red circled X drawing, which is exactly the standard for a functional image.","subtype":null}
{"item_id":"fi-4921","verdict":"keep","alt_quality":"good","reason":"Functional: an area of a clickable US forecast map linking to the Miami office. The alt names the region the area covers, which is the destination, and no two areas share a name.","subtype":null}
{"item_id":"fi-9378","verdict":"keep","alt_quality":"good","reason":"Functional: an input type=image that submits a donation form. The alt names the outcome of pressing it rather than describing the PayPal badge artwork.","subtype":null}
{"item_id":"fi-5773","verdict":"drop","alt_quality":"weak","reason":"Functional, but the reference is ambiguous: the link's aria-label announces \"home page\" while the image's own alt says \"AP Logo\". One is good and one names the picture, so there is no single shipped alt to score against.","subtype":null}
{"item_id":"fi-10607","verdict":"drop","alt_quality":"weak","reason":"Functional: the Wikipedia wordmark links to the main page, so it is a linked logo. The alt is the bare brand name and says nothing about the destination.","subtype":"linked-standalone-logo"}
{"item_id":"fi-0380","verdict":"drop","alt_quality":"weak","reason":"Functional: a menu toggle button. The SVG labels itself \"AngleDown\", which names the glyph shape rather than what the control does, and it competes with the button's own \"menu\" label.","subtype":null}
{"item_id":"fi-1784","verdict":"keep","alt_quality":"good","reason":"Functional: an input type=image that submits the site search. The alt names the action performed rather than the magnifier drawing.","subtype":null}
{"item_id":"fi-5153","verdict":"keep","alt_quality":"good","reason":"Functional: an area of the national forecast map linking to the Gaylord office. The alt names the region, which is the destination. The stray attributes in the markup are the site's own malformed HTML, sliced verbatim.","subtype":null}
{"item_id":"fi-1800","verdict":"drop","alt_quality":"weak","reason":"Functional: the MIT logo links to the site root. But the announced name comes from a visually hidden heading next to it, and the graphic itself carries no description at all, so there is no image and alt pair to confirm.","subtype":null}
{"item_id":"fi-5774","verdict":"drop","alt_quality":"weak","reason":"Functional: the hamburger opens the site menu. The button already has the visible text \"Menu\", so the icon is decorative by context and no alternative text was written for it.","subtype":null}
{"item_id":"fi-10608","verdict":"drop","alt_quality":"weak","reason":"The tagline wordmark is one of three images making up the logo link, and its alt transcribes the graphic instead of naming the destination. As a functional image the alt is weak.","subtype":null}
{"item_id":"fi-9379","verdict":"drop","alt_quality":"good","reason":"Not functional: a book cover thumbnail inside a link to the book. The cover conveys what the book looks like, and the link text next to it carries the label, so this is an informative image in a link, not a functional one. The empty alt is correct.","subtype":null}
{"item_id":"fi-5297","verdict":"keep","alt_quality":"good","reason":"Functional: an area of the marine forecast map linking to the Fairbanks office. The alt names that office, which is the destination.","subtype":null}
{"item_id":"fi-0002","verdict":"drop","alt_quality":"weak","reason":"Functional: a second ThriftBooks logo variant linking to the site root. Same finding as the first: bare brand name, no destination.","subtype":null}
{"item_id":"fi-1591","verdict":"keep","alt_quality":"good","reason":"Functional: the search toggle in the MDN header. The announced name \"Search the site\" names the action and the scope, which is what a person needs from an icon-only control.","subtype":null}
{"item_id":"fi-1841","verdict":"keep","alt_quality":"good","reason":"Functional: aria-expanded shows this is a search panel toggle rather than a plain navigational link, so the sub-type is corrected. The aria-label names the action the icon performs.","subtype":"action-or-toggle-icon"}
{"item_id":"fi-9406","verdict":"drop","alt_quality":"weak","reason":"Functional: the Project Gutenberg logo links to the site root. The alt is the bare project name and does not say the link leads home.","subtype":null}
{"item_id":"fi-10750","verdict":"keep","alt_quality":"good","reason":"Functional: a menu button. Two correct decisions together: the icon carries alt=\"\" because the button is labelled, and the button's label names the action. This is the pattern the corpus should teach.","subtype":null}
{"item_id":"fi-6349","verdict":"drop","alt_quality":"weak","reason":"The chevron sits beside the visible link text \"World\" and adds nothing a person needs announced. It is decorative by context and carries no alternative text.","subtype":null}
{"item_id":"fi-5375","verdict":"keep","alt_quality":"good","reason":"Functional: an area of the western region climate map linking to the Fairbanks office. The alt names that office. A different map image from fi-5297, so not a duplicate.","subtype":null}
{"item_id":"fi-0412","verdict":"drop","alt_quality":"wrong","reason":"Functional: the account button. But the label \"User1\" is an internal component or asset name leaking into the interface. It names neither the action nor the destination and would confuse anyone hearing it.","subtype":null}
{"item_id":"fi-1880","verdict":"drop","alt_quality":"weak","reason":"Functional: the footer logo links to the university home page. The alt is the bare institution name, not the destination.","subtype":null}
{"item_id":"fi-9422","verdict":"drop","alt_quality":"weak","reason":"Functional: a link to the project's Facebook page. The alt describes the picture and repeats its type with the word \"icon\" instead of naming the destination.","subtype":null}
{"item_id":"fi-6689","verdict":"drop","alt_quality":"weak","reason":"Functional: the NPR logo links to the site root. The alt is the brand name plus the word \"logo\", which describes the image rather than where it goes.","subtype":null}
{"item_id":"fi-1639","verdict":"drop","alt_quality":"weak","reason":"Functional: a play control on the W3C home page. The SVG is deliberately aria-hidden and the button's own visually hidden text carries the label, so no alternative text was written for the graphic.","subtype":null}
{"item_id":"fi-10679","verdict":"drop","alt_quality":"weak","reason":"Functional: the Wikimedia Commons wordmark links to the main page, so it is a linked logo. The alt is the bare project name.","subtype":"linked-standalone-logo"}
{"item_id":"fi-2615","verdict":"drop","alt_quality":"weak","reason":"Functional: the accordion toggle in the federal site banner. The button already reads \"Here's how you know\", and the chevron carries no alternative text of its own.","subtype":null}
{"item_id":"fi-10709","verdict":"drop","alt_quality":"weak","reason":"Functional: the Wikimedia Foundation logo links to the foundation site. The alt is the bare organisation name and does not name the destination.","subtype":null}
