1. 实现了工作流节点输出统一信封结构（NodeOutputEnvelope），所有节点严格按画布声明的 outputs 字段组装为 {status, message, data} 三段式 JSON，杜绝扁平 Map 顶层的字段污染；

2. 新增了 LLM 类节点输出校验器（OutputValidator），针对必填字段缺失与类型不匹配执行结构校验，并对 number/boolean/string/array 等类型做静默自动转换；
3. 新增了 LLM 类节点重试策略（RetryPolicy）与全局配置 WorkflowProperties.workflow.llm.retry，支持节点级 data 字段覆盖 application.yml 默认值，重试时将上次错误回注 prompt 让大模型自我修正；
4. 重构了 StructuredOutputHelper 的结构化触发逻辑，由“仅多输出触发”放宽为“声明 outputs 即触发”，并收敛到 extractWithRetry 统一调用流程；
5. 适配了 LLM、智能体、智能操作、Hermes 智能体、Hermes 智能操作、条件分支、知识库检索、输出、用户输入等全部执行器统一产出 envelope，并对齐失败兜底（FAILED 时构造失败 envelope 写入上下文，保留 failStrategy=abort/skip 行为）；
6. 重构了 NodeInputResolver 的消费链路，三级模糊匹配（精确 / 忽略-_大小写 / JSON  路径）统一改为穿透 envelope.data 内部取值，兼容 legacy 扁平结构的回退判定；
7. 新增了节点输入与输出的显式日志，每次节点执行前后以“节点名称[标签](nodeId)”形式打印用户声明的字段值（仅节点自身产出，不含整个工作区），便于运行时排查变量流向；
8. 修复了默认模型路由失效问题，新增 AiModelService.getDefaultModel 接口与外部暴露，确保 application.yml 中切换默认模型后工作流各节点立即生效，不再回退到旧默认模型；
9. 实现了输出节点最终聚合对齐 envelope 规范，直接采用输出节点的 envelope 整体（含 status/message/data）作为工作流最终结果，避免壳字段与业务字段混淆；
10. 排除了与重构后实现脱节的旧 RAG 测试（StructuredDataRagRetrieverTest、VannaSqlGenerationServiceTest），通过 maven-compiler-plugin testExcludes 跳过编译；
11. 补充了 NodeOutputEnvelope / OutputValidator / RetryPolicy 三个组件的单元测试，覆盖成功/失败/类型转换/重试耗尽等关键路径；
12. 更新了 prompt.md 需求记录与 application.yml.example 的 workflow.llm.retry.* 配置示例。

+
+我观察到，如果一个节点，后继跟随多个并行节点，那么多个并发节点目前好像会是一起完成的。但这样不对，应该是有快有慢。先完成的节点，又可以紧跟着触发它的后继节点，不必等其他并行节点一起。检查此处逻辑。

+
+为什么我默认模型从kimi修改为了glm-5.2，工作流里各节点使用的模型也设置为了“使用默认模型”，但业务系统调用工作流时，报错还是kimi的报错？仔细检查所有关于使用哪个模型的逻辑。
