Historical URLs are reviewed individually. A past URL is not automatically a page we can or should restore.
Bibliographic record
A limited record may name the historical title, date and URL without copying the article body or implying current ownership.

Unknown, spammed or rights-unclear paths remain genuinely unavailable. They are not sent to the homepage for the sake of link equity.
New publication
New articles have their own URLs and stand on their own evidence. They do not impersonate a historical continuation.
