### 前端合并与渲染（回合唯一归属，连续工具成块）
- 加载对话时按历史条目进入 `project.jsonl` 的原始顺序投影：用户消息、文本与工具块保持原序，连续工具合为一块、遇到文本另起一块，不按 `turnId` 重新归并、也不再有 `seq` 交替。
-- 回合完成后，中间文本及所有工具块统一收进默认关闭的“执行过程”；最终回复及失败提示留在外面。展开后仍按原顺序查看中间输出和工具详情；运行中不使用外层折叠区。用户消息的发送时间从消息自身的历史时间读取，不能拿工具起点补造。
+- 回合完成后，中间文本及所有工具块统一收进默认展开的“执行过程”；最终回复及失败提示留在外面。用户仍可收起过程块，重开项目后过程默认再次可见；运行中不使用外层折叠区。用户消息的发送时间从消息自身的历史时间读取，不能拿工具起点补造。
- 实时与回读共用同一投影，正文、工具和耗时不另建实时/未归属渲染出口。先在完整历史按消息身份关联，再分页；禁止按第 N 个工具回合匹配第 N 条用户消息。详情通过当前回合 `callId` 关联；同项目回读与实时增量幂等合并，切项目清空旧状态。完整合同见 [AGC 实施计划](./【技术方案】AI游戏创作智能体App实施计划-2026-06-24.md) 的“DirectProject 回合展示唯一归属”。
