Phase 3 能力: - DAG 并行执行 (workflow_engine): asyncio.gather 并行执行就绪节点 - Debate 并行 (orchestrator): for 循环改为 asyncio.gather - 粒度进度上报 (workflow_engine + tasks + websocket): Redis 推送 + DB 降级 - 工具结果缓存 (tool_manager): 确定性工具默认开启缓存 - LLM 响应缓存 (core): messages[-4:] + model 哈希，5min TTL AgentChat bug 修复 (Gitea #1-#5): - #1 SSE 降级重复空消息: fallback POST 前移除占位消息 - #2 streamTimeout 泄漏: while 正常退出后 clearTimeout - #3 loading 闪烁: final/error 事件中提前设 loading=false - #4 SSE 事件类型对齐: 确认匹配，未知类型加 console.warn - #5 retryMessage 流式残留: 重试时清理占位消息 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
