Losita b1eb6bedf9 Version: 0.9.1.dev.260406
后端:
  1.新建conv/schedule_persist.go:ScheduleState Diff 持久化,事务内逐变更写库,支持 place/move/unplace 三种操作(当前
  event source)
  2.新建conv/schedule_provider.go:ScheduleState 加载适配,从 DB 合并 existing events + pending task items
  3.新建dao/agent_state_store_adapter.go:Redis 状态快照存取适配,实现 AgentStateStore 接口
  4.新建service/agentsvc/agent_newagent.go:newAgent service 集成层,串联 LLM
  客户端、ScheduleProvider、SchedulePersistor 和 ChunkEmitter
  5.更新node/execute.go:接入 SchedulePersistor(写操作确认后持久化)、完善 confirm resume 路径(PendingConfirmTool
  恢复分支)、correction 机制增加连续失败计数上限
  6.更新api/agent.go + cmd/start.go:接入 newAgent service,完成 API 层路由注册
  7.新建node/execute_confirm_flow_test.go + llm_tool_orchestration_test.go:确认回路 7 个测试 + 端到端排课 5
  个测试全部通过
  8.新建newAgent/ARCHITECTURE.md + ROADMAP.md:全链路架构文档和缺口分析
  9.代码审查整理:提取 prompt/base.go(通用 buildStageMessages 等5个辅助)、tools/args.go(参数解析辅助);write_tools
  尾部辅助移入 write_helpers;修复 queryRangeSpecific sb.Reset() 逻辑缺陷和 Unplace guest Duration
  未恢复;ScheduleStateProvider/SchedulePersistor 归入 state_store.go;emitter 内部 Build*Text 函数降级为私有
前端:无
仓库:无

// NewSSEPayloadEmitter 创建将 chunk 事件写入 outChan 的 emitter。
//
// 职责边界:
// 1. 接收 outChanSSE 输出通道),返回 PayloadEmitter 函数;
// 2. 只把原始 JSON payload 写入通道,不添加 "data: " 前缀和 "\n\n" 后缀;
// 3. SSE 格式化("data: " + payload + "\n\n")由 API 层的 writeSSEData 统一处理;
// 4. 发送失败时返回 error但不关闭通道通道由调用方管理
//
// 使用示例:
//
// emitter := NewSSEPayloadEmitter(outChan)
// chunkEmitter := NewChunkEmitter(emitter, requestID, modelName, created)
// chunkEmitter.EmitAssistantText("", "", "hello", true)
func NewSSEPayloadEmitter(outChan chan<- string) PayloadEmitter {
return func(payload string) error {
if outChan == nil {
return nil
}
if payload == "" {
return nil
}
select {
case outChan <- payload:
return nil
default:
// 通道已满或已关闭:不阻塞,直接返回错误。
return fmt.Errorf("outChan full or closed")
}
}
