- A public post that links to a page gets a preview card: from the post's own data first (FEP-8967 Link preview, the object's image, title and summary); otherwise the server reads the page once, 0-60 s after the post arrives, never when someone reads it. OpenGraph and Twitter tags give title, description and image; one LinkPreview per address is cached for 7 days and shared by the whole server, so a fetch never points at a persona. - Lemmy link posts, which carry no title or description, get them filled in. - The page fetch uses the guarded client (public addresses, three redirects, HTML only, first 512 KB). - Federation:FetchLinkPreviews switches page fetching off. - Local public posts get cards too. Checked live: a link to a GoToSocial profile page becomes a card with its title, description and proxied image.
