+
+## 目标

+
+## 范围
+
+- DocTaskPlan / PreviewSummary / ProjectSettings 扩展
+- ResolveDocTaskDuty、Save/Preview/Activate 消费 U1 策略
+- Goose 00051 token revision 列
+- app 适配器装配、HTTP 错误码映射
+- 单元测试
+
+## 非目标
+
+- Heal/文档投影（U3）
+- 前端 UI（U5）
+- 运行时动作多职责（U4/U6）
+
+## 步骤
+
+1. [x] 类型与解析器
+2. [x] service/store/迁移
+3. [x] app 装配与 handler
+4. [x] 测试与提交
+
+## 验收标准
+
+- [x] 一位成员兼任可存/预览/激活（总开关开）
+- [x] 总开关关时 Save 拒绝
+- [x] 预览后 revision 变化旧 token 409
+- [x] 未开模式只填作者仍 partial 拒绝
+- [x] 旧快照缺 duty_policy 时 hash 稳定
