Legacy ``fallback_model`` entries are appended afterwards unless they target the same provider/model/base_url route as an earlier entry. The returned list always contains fresh dict copies. )fallback_providersfallback_model)setrrr!addr)configchainseenkeyridentitys r get_fallback_chainr,3sn\rF"$E&)eD7+FJJsOr3s"L"% :r
