key_decisions:
|
|||
|
|
- decision: "复用现有 OutputFilter 组件，通过 OutputGuardrailExecutor 封装"
|
|||
|
|
reason: "避免重复实现，保持代码一致性"
|
|||
|
|
impact: "OutputGuardrailExecutor 在 dialogue.py 中注入并强制调用"
|
|||
|
|
- decision: "全链路超时从 30000ms 调整为 8000ms"
|
|||
|
|
reason: "AC-MARH-09 要求全链路 <=8000ms"
|
|||
|
|
impact: "timeout_governor.py 的 DEFAULT_END_TO_END_TIMEOUT_MS 已调整为 8000"
|
|||
|
|
- decision: "新增 InterruptContextEnricher 组件处理 interrupted_segments"
|
|||
|
|
reason: "AC-MARH-03/04 要求打断语义可消费、可兜底"
|
|||
|
|
impact: "新建组件文件，在 respond 流程中调用"
|
|||
|
|
- decision: "新增 MetadataFilterBuilder 组件实现元数据驱动过滤"
|
|||
|
|
reason: "支持动态参数生成，无需改代码即可生效"
|
|||
|
|
impact: "复用现有元数据字段定义能力，基于字段配置动态装配过滤参数"
|
|||
|
|
- decision: "新增 kb_search_dynamic 工具替代固定入参的 KB 检索"
|
|||
|
|
reason: "AC-MARH-05 要求 Agent 默认基于 KB 事实回答"
|
|||
|
|
impact: "工具注册到 ToolRegistry，在 Agent 模式下自动调用"
|
|||
|
|
- decision: "新增 high_risk_check 工具实现元数据驱动的高风险检测"
|
|||
|
|
reason: "AC-IDMP-05/20 要求高风险场景最小集可配置，支持多租户隔离"
|
|||
|
|
impact: "工具从 HighRiskPolicy 表读取规则，支持关键词+正则匹配，高风险优先于普通意图路由"
|
|||
|
|
- decision: "新增 memory_recall 工具实现短期可用记忆注入"
|
|||
|
|
reason: "AC-IDMP-13 要求对话前读取用户可用记忆，减少重复追问"
|
|||
|
|
impact: "工具读取 profile/facts/preferences/last_summary/slots，超时 <=1000ms，失败不阻断主链路"
