Struct ProviderUse 

pub struct ProviderUse {
    pub index: usize,
    pub model: String,
    pub location: String,
    pub files: usize,
}

One provider’s share of a run.

The backend location is carried, not just the model, because “gpt-5.6-sol” does not tell a user whether they paid for it - two entries can name the same model at a local proxy and at the vendor.
