Can't identify Personal Vault folder in the API so can't skip them reliably

[ncw]

It isn't possible to read the contents of "Personal Vault" folders via the API so I would like to skip them. However there isn't a unique identifier for these folders that I can see.

Ideas

• Use the name: it might be localized.
• Use absence of webUrl: might be OK but for all I know is missing for other content
• Use siteURL == https://my.microsoftpersonalcontent.com/personal/XXX: that domain is not specific to personal vault it is used all over onedrive

Can we rely on one of these as a unique identifier?

If not can you add one please?

Here is how they appear at the moment

  "createdDateTime": "2025-07-01T03:58:19Z",
  "eTag": "XXX",
  "id": "XXX",

An rclone user reports that the name "Personal Vault" is localised which make detecting the folder even harder.
