Determines the destination of the new share, whether a webhook fires, and what BackupLocation tag is applied. Defaults to `rootUser` for backwards compatibility with clients that don't yet pass the field. * `rootUser` — refresh/rotate the user's primary shares (password change, key rotation). Shares stay on the user's device + Dynamic. * `cloudBackup` — add a cloud-stored share (Google Drive / iCloud). Encrypted with the user's password and uploaded to the third-party provider determined by request context. * `delegation` — add a delegated signing share. Encrypted with the env's delegated-access RSA key and POSTed to the env's `delegatedAccessEndpoint`. Includes an encrypted wallet API key so the developer can sign on behalf of the user. * `offlineRecovery` — add a non-signing recovery share. Same endpoint + RSA key as `delegation`, but no API key in the payload and the resulting share is tagged `BackupLocation: 'offlineRecovery'` so wallet-service refuses to use it for signing.
