 - **表单一所有者原则 (Single Owner Principle)**：
   - 每张数据表有且仅由一个所有者插件声明与维护（表名使用插件前缀如 `w_order_*`）。

 ### 5.1 彻底根除集中式包与建立 backend/ 顶级总包
 在过去的传统单体架构中，集中式的 `internal/model/`、`internal/repository/` 以及 `internal/` 目录往往成为大杂烩，随着团队扩展导致模块边界失控与隐式耦合。在本次 Cordis 架构重构中，我们实施了彻底的物理清退与顶级前后端分包：
 - **`backend/` 顶级总包**：汇聚所有 Go 后端代码（`cmd/`、`core/`、`plugins/`、`pkg/`、`main.go`），根目录仅保留顶级功能域。
+- **配置读取框架归属内核**：`backend/core/extpoints/` 只承载与实现无关的配置声明与解析引擎（不 import viper），`backend/plugins/infra/config/` 承担文件与环境装载，读哪些字段由各插件自行声明；组合根不再跨插件判断配置选实现，改由 `ConfigGatedPlugin` 门禁 + `FiberSkipped` 决定激活方。
+- **`pkg/config/` 全局单例**：处于退场过渡期。配置声明与解析能力已上收内核，业务侧全量迁移与旧包物理清退由后续迁移计划落地。
 - **`internal/` 目录**：**100% 物理清除**。通用的无状态基础库平移至 `backend/pkg/`，所有业务全部下沉至 `backend/plugins/domain/`。
 - **`pkg/model/` 目录**：**100% 物理清除**。消灭集中式数据模型。

+## 6. Cordis 配置扩展点与条件门禁机制 (Config Extension & Gated Activation)
+
+### 6.1 彻底清退全局配置单例 (Zero-Singleton Architecture)
+在传统单体架构中，`pkg/config.Config` 全局静态变量充斥在各个业务与驱动模块中，导致隐式依赖、无法独立单测、无法多实例共存。Cordis 架构引入了基于微内核上下文的配置扩展点（`ctx.Config()`）：
+- **插件自包含声明**：每个插件实现 `DeclareConfig() []core.ConfigBinding`，声明自身所需的静态启动配置前缀、结构体与字段 tag（`config`、`env`、`default`、`autoEnable`、`secret`）。
+- **统一生命周期解析**：通过 `app.Prepare()` 建立配置解析屏障，统一绑定 YAML 文件与环境变量，支持前缀冲突检测与敏感字段脱敏导出。
+- **纯净依赖隔离**：插件在 `Apply(ctx)` 中通过 `ctx.Config().Bind("<prefix>", &cfg)` 读取自身配置，微内核与 `pkg/` 工具包绝对不依赖任何配置具体实现。
+
+### 6.2 基于配置的动态插件门禁 (Configuration-Gated Plugins)
+为了原生支持**单机单体（Zero-Redis Monolith）**与**分布式集群（Distributed Cluster）**无缝切换，Cordis 提供了 `core.ConfigGatedPlugin` 扩展接口：
+- **门禁契约**：实现 `ConfigEnabled(view core.ConfigView) bool` 方法。微内核在 `Reconcile` / `ApplyPlugins` 阶段依据解析后的配置动态求值。
+- **互斥挂载**：
+  - 当 `redis.enabled = false`（默认）：`cache_memory`、`driver_inproc_worker` 与 `driver_inproc_cron` 自动进入 `ACTIVE` 状态；分布式插件进入 `SKIPPED` 状态，达成零外部中间件极简单体。
+  - 当 `redis.enabled = true`：`cache`、`driver_asynq_worker` 与 `driver_asynq_cron` 自动激活，无缝升级为分布式高可用架构。
+- **动态拔插可组合性**：所有互斥插件可同时通过 `app.Use(...)` 注册，装配根无需编写侵入式的 `if-else` 条件分支，全面实现架构的时空可组合性与高内聚。

+## 8. 落地回写（P1 + P2 已实施）
+
+实施结果与本设计原述的差异，均已按下列口径落地：
+
+| # | 设计原述 | 落地结果 | 缘由 |
+| :--- | :--- | :--- | :--- |
+| R1 | §4.3 C1、§6 把 `app.session_age<=0` 列为内核解析错误 | 引擎不做值域校验，`ErrConfigInvalid` 保留但未在内核使用；值域由声明者在 `Bind` 之后校验（P3 由 auth 承担） | 引擎被设计成不认识任何业务 key 的语义，把业务规则塞进内核会破坏该不变式 |
+| R2 | §3.2 `ConfigView.Source(key)` | 更名 `Origin(key)`；新增 `Value(key) (any, bool)`；`ConfigExtension` 增加 `SetSource`、`Resolved` | `Source` 与类型名 `ConfigSource` 同文件易混淆；`Value` 支撑 `core.ConfigGet[T]`（Go 方法不能带类型参数）；`SetSource` 进接口以免运行时类型断言 |
+| R3 | §3.5 仅有 `WithShutdownTimeout` | 新增 `App.ShutdownTimeout()` 与 `SetShutdownTimeout(d) *App` | 组合根需在 `Prepare()` 之后把已解析预算写回内核，构造期选项无法表达该顺序 |
+| R4 | §4.2 时序图把门禁求值画在 `Prepare()` 内 | `Prepare()` 只建立解析屏障，门禁在 `reconcileLocked` 每轮调和中求值 | `App.Use` 可在 `Prepare()` 之后继续挂载插件；只在 `Prepare` 求值会留下一批永不判定的门禁 |
+| R5 | 未涉及 | `App` 未注入 `ConfigSource` 时配置能力视为未启用，解析屏障直接放行；实现了 `ConfigGatedPlugin` 却无配置源的插件 fail fast 点名原因 | 内核存在大量不使用配置的装配路径（既有测试与嵌入式用法），不能强制要求配置源；但门禁无数据可依时必须报错，而非静默全激活 |
+| R6 | §4.1 隐含"每个 key 都有 env 覆盖" | env 覆盖面完全由声明决定。旧装载器只对部分 key 提供 env（`slow_threshold`、`conn_max_lifetime` 等从未有 env 覆盖），对拍镜像必须精确复刻该覆盖面 | 否则对拍出现假漂移；放宽某 key 的 env 覆盖是 P3 的声明选择，不构成引擎行为变更 |
+| R7 | §4.1 "向上最多 5 层查找 `config.yaml`" | 该向上查找会**越出 git worktree 边界**：从 `backend/pkg/config` 出发第 5 层可命中父级检出的 `config.yaml` | 属既有行为、非本次引入，但在 worktree 中开发会静默使用另一份检出的配置。对拍测试已改为以入库的 `config.example.yaml` 所在目录为锚；`config.yaml` 本身被 gitignore，干净克隆中不存在 |
+
+分期口径：本设计 §7.3 的 P1 + P2 已实施完成；P3（27 个消费文件迁移、`pkg/idgen` 解耦）与 P4（删除 `backend/pkg/config`、移除对拍夹具）由后续计划承接。
