Function create 

pub async fn create(
    client: &DriveClient,
    opts: &CreateOptions,
    rules: &[FolderPermissionRule],
) -> CreateOutcome

Creates opts.name inside opts.parent_folder_id, gated by rules (the active account’s write_permissions.rules).

Every real (non-dry-run) attempt — created, blocked, or failed — is logged via request_log::record_drive_mutation, even when the gate refused before any Drive API call was made. A --dry-run preview is never logged, matching drive move’s existing precedent (its CLI layer calls file_move::plan but never execute under --dry-run, and only execute logs).
