 A failure is declared once, by the lowest crate that raises it. Every crate above nests that error unchanged (`#[error(transparent)] Auth(#[from] litellm_auth::Error)`) or maps it once at its boundary, as `src/error.rs` does for `litellm_llms::Error`. `RouteError` collects route failures and never re-declares a variant a lower crate raises
