验收指标对照表:

验收项原始问题修复方案验证结果
INTENT['greeting'] 关键词非空且≥3个原只有2个关键词 ['你好', 'hello'],被截断补全为5个:['你好', 'hello', 'hi', '嗨', '早上好']✅ 通过
INTENT['product_info'] 关键词非空且≥3个原有6个关键词,无问题保持不变✅ 通过
INTENT['price_inquiry'] 关键词非空且≥3个原有5个关键词,无问题保持不变✅ 通过
INTENT['technical_support'] 关键词非空且≥3个原有6个关键词,无问题保持不变✅ 通过
INTENT['feature_request'] 关键词非空且≥3个原只有2个关键词 ['新功能', '建议'],被截断补全为5个:['新功能', '建议', '改进', '优化', '需求']✅ 通过
INTENT['complaint'] 关键词非空且≥3个原有5个关键词,无问题保持不变✅ 通过
模块可正常导入并执行路由逻辑原代码因截断导致字典定义不完整,import报错修复后完整定义所有6种意图的关键词列表✅ 通过
