后端： 1. 服务级 outbox 基础设施全量落地——新增 service route / service catalog / route registry，重构 outbox engine、repository、event bus 和 model，按 `event_type -> service -> table/topic/group` 统一写入与投递，保留 `agent` 兼容壳但不再依赖共享 outbox 2. Kafka 投递、消费与启动装配同步切换——更新 kafka config、consumer、envelope，接入服务级 topic 与 consumer group，并同步调整 mysql 初始化、start/main/router 装配，保证各服务 relay / consumer 独立装配 3. 业务事件处理器按服务归属重接新 bus——`active-scheduler` 触发链路，以及 `agent` / `memory` / `notification` / `task` 相关 outbox handler 统一切到新路由注册与服务目录，避免新流量回流共享表 4. 同步更新《微服务四步迁移与第二阶段并行开发计划》，把阶段 1 改成当前基线并补齐结构图、阶段快照、风险回退和多代理执行口径

// 2. MarkTriggerFailedBestEffort 负责事务外的失败回写，避免 outbox retry 前完全没有业务态可查；

//
|
||
// 步骤化说明：
|
||
// 1. 先做 envelope -> contract DTO 解析与版本校验，明显坏消息直接标记 dead；
|
||
// 2. 再通过 ConsumeAndMarkConsumed 把“业务落库 + consumed 推进”收敛在同一事务里；
|
||
// 3. 若事务返回 error，则 best-effort 回写 trigger failed，并把错误交给 outbox 做 retry；
|
||
// 4. 这里不直接 import active_scheduler 的具体实现，避免 service/events 和业务编排层互相反向耦合。
