- 补 8 个标准字段（还款来源/涉诉/增信/保证金/保险/客户名称），对齐原生方法文档声明的 inputs - 字段守卫改为比对标准字段表，不再把"标准字段但本次无数据"误判为未知字段 - 向模型下发 standard_fields 并在提示词约束字段名，避免自造派生指标 - 补 insurance./deposit. 维度前缀；方案预算 12→18、120s→180s，版本升 1.1.0 实测（临时库 + DeepSeek）：模型类技能由 failed 转为 partial（部分 unknown 属如实标注）， 降级记录为空，工具调用 11 次。字段表三处为代码层改动，对既有库即时生效。 验证：scripts/verify.py 11/11 PASS，531 项单测。 Co-Authored-By: Claude Code <noreply@anthropic.com>
