-             * @description Optional cap on each individual prior turn's text, applied before classifier_context_budget_chars bounds the block. Unset by default, so one long turn may spend the whole budget, which is usually what a follow-up needs; set it when no single turn should dominate the context the classifier sees. A capped turn keeps its opening and its ending with the middle elided. Only applies when classifier_type is 'llm'.
