// ABOUTME: with_default_model replaces the configured model on Gemini, Groq and the local provider
// ABOUTME: A chain's second tier must resolve its own model name, not the first tier's, or its API 404s

//! A fallback tier constructed with the primary's model name issues requests
//! against a model its API has never heard of — a Gemini secondary asked for
//! a Claude model 404s on every call, and the chain collapses whenever the
//! primary is unavailable. `with_default_model` is the override that gives
//! the tier its own model; these pin that it actually rewrites the field.
