follow-up suggestion count must be between 1 and 5

Error message

follow-up suggestion count must be between 1 and 5

What it means

Configuration validation in QuestionSuggestionConfig.Validate: the follow-up suggestion Count is outside the allowed 1–5 range. The tighter cap (versus 8 for starters) reflects per-turn follow-up cost; the config is rejected before persistence to avoid expensive suggestion generation with an invalid count.
