The summary is written by the turn's own model unless `[context] summarizer_model` (`OPENHUMAN_CONTEXT_SUMMARIZER_MODEL`) names another; that model is called on the turn's provider route, with the same credentials and endpoint (`inference/turn_models.rs`). Each turn logs its choice at debug as `[context_compression] summarizer model= source=config|turn`.
