+# Phase 02 Plan 02: 实名激活架构重构 Summary
+
+将 `enable_realname_activation` 布尔字段替换为 `expiry_base` 枚举（from_activation/from_purchase），重构激活决策为三维判断（卡类型+购买路径+expiry_base），全链路原子完成。

+| Task | Description | Commits |
+|------|-------------|---------|
+| 1 | DB 迁移 + Model + Store 清理（REALNAME-01） | `344850f` |
+| 2a | DTO 更新（REALNAME-05） | `244a274` |
+| 2b | activateMainPackage 三维决策（REALNAME-02） | `7dd5563` |
+| 2c | C 端实名检查按卡类型（REALNAME-03） | `0ebb3d7` |
+| 2d | ActivateByRealname 按 ExpiryBase 选时间基准（REALNAME-04） | `60b43bb` |
+| 2e | auto_purchase.go 废弃引用清除（偏差修复） | `4be473c` |
+
+## Verification
+
+```
+migrate-version: 89, dirty=false ✓
+EnableRealnameActivation/enable_realname_activation/packagesNeedRealname 零引用 ✓
+ExpiryBase 引用出现在 package.go、package_dto.go、order/service.go、
+          client_order/service.go、activation_service.go ✓
+go build ./internal/... 零错误 ✓
+```

+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] auto_purchase.go 含废弃 EnableRealnameActivation 引用**
+- **发现于：** Task 2 完成后编译验证
+- **问题：** `internal/task/auto_purchase.go:433` 引用已删除的 `pkg.EnableRealnameActivation` 字段，导致编译失败
+- **修复：** 识别 auto_purchase 为 C 端充值触发路径，不适用 expiry_base 三维决策，删除该分支并添加注释说明
+- **文件：** `internal/task/auto_purchase.go`
+- **Commit：** `4be473c`
+
+**2. [Rule 1 - Bug] package/service.go DTO 映射引用 EnableRealnameActivation**
+- **发现于：** Task 2 DTO 替换后 LSP 报错
+- **问题：** `service.go` 的 Create/Update/toResponse 函数仍映射旧字段
+- **修复：** 同步更新三处映射为 `ExpiryBase`
+- **文件：** `internal/service/package/service.go`
+- **Commit：** 含于 `244a274`
+
+## Known Stubs
+
+无已知留桩。全链路变更已完整实现。
