 事实 key 的写入校验拒绝首尾空白，默认 SQL 范围过滤兼容已有 key 的 Unicode 空白，与 Go 判断一致；读取不会批量改名或迁移旧记录。索引成功构建为空时会移除旧索引块，其他系统内容及用户账本保持；数据库读取失败时继续保留原索引。
 
 黑板短标签优先使用第 8 节中已经生成的证据检索线索；没有可用线索则沿用原先的标签取法。只更改索引标签，不改摘要第 1–7 节、完整正文或原始用户账本，不增加模型调用。新增 `Context memory` CI 在 macOS、Ubuntu、Windows 上直接运行 agent/app/database/handler/multiagent/project/projectprompt 的并发回归测试；Windows 不检查其文件系统不支持的 Unix 权限位。

+计划执行和重新规划的用户角色消息是系统生成模板，包含计划与模型/工具结果，不等于用户新输入。模板使用独立的允许列表来源字段，生成前从未拼接的原始消息保存受限用户账本，再进入重写/压缩；角色与来源也保留在输入文本和快照中。恢复轨迹及框架的用户消息区块不会把模板内容归入用户原文，模板中的工作进展仍保留给模型使用。普通用户引用计划或摘要文字继续作为真实输入处理。
+
+上下文超限或临时故障重新启动时，移除旧指令与索引，但保留并按当前预算重建结构化原始用户账本。首条长输入的预算计算包含编号、分隔符和省略号，避免有空间却整条丢弃；只保留原文的受限片段，不增加用户输入的模型摘要。预算仍不能保存无限原文，精确细节按需回读快照。
+
+已有首尾空白 key 的事实可按原 ID、项目和完整 key 更新摘要/正文，不改名、不修改历史关系引用；新建及更改为非规范 key 仍被拒绝。真实 HTTP 部分更新回归覆盖这一兼容路径。
+
+验收还覆盖长工具输出先保存为原文文件、压缩与恢复后从快照获得文件引用，再通过 read_file 后端分段回读精确 Cookie。合成 Cookie 放在 2001 行输出的中间，不出现在截断预览或摘要中；classic/native 两种路径均可完整恢复。这里只保证证据与读取入口可用，模型是否主动回读取决于任务与模型行为。
+
+页面、聊天输入、审批交互和 API 路由没有改动；常规操作沿用原流程。新增可见内容是自动续接记录和简短读取提示，同项目其他会话的自动工作记录默认不注入，普通共享事实与手工 note 保持原有读取方式。本地快照随不同压缩内容累计，沿用会话产物删除生命周期。
