2. and 3. sound like sensible options. Though none of the options is inherently wrong. But the first one doesn’t sound easily reproduceable.

For 2: see the other comment https://feddit.org/post/25212909/11301373

For 3: i think you can also create a “host” terminal in vscode? (Maybe i’m remembering wrong). Then you can simply cd to your project and use git etc as usual

It sounds like verifying the integrity of servers to me and used by the administrator
