Where are articles from the Sandbox visible on Habré, except for the address habrahabr.ru/sandbox/?

Question

Habr

Indeed, during the creation of an article, it is possible to specify profile hubs. But I didn’t see the article in those hubs. Or will the article appear in the hub after receiving an invite?
I indicated the hub with an asterisk if it means something in my case. I have a read-only account.
("Will appear in the hub" I wrote for completeness of the question, because it's hard to believe in such a possibility, looking at the average number of comments in the sandbox).

Answer 1

Until the post is in the Sandbox and an invite is issued for it, it will only be in the Sandbox.
It gets into the hubs only after the issuance of an invite for the post and, accordingly, after the automatic transfer of the account from readonly to a full-fledged one.
Well, about the comments in the Sandbox, they are not there, as it were)
