How Entries Are Kept
A name ending in … is a prefix: it covers every
cookie whose name starts that way. Some short names mean something only on
the sites that own them, and those entries say which sites.
A cookie missing from this list is not a verdict on it. Several large companies publish no citable name for their cookies, and an entry without a source that names the cookie would be a guess. Those stay unknown.
"Needed to work" means the site breaks, or signs you out, without it. Most of those are security features: fraud checks, request-forgery protection and sign-in sessions.
