 - `/seen` `(/info)`
 - `/tpsbar`
 - `/essc admin` 管理模式切换
+- `/maintenance` `(/maint)` 维护模式管理
 
 ### 其它功能
 
 - Shift + 右键快捷打开潜影盒
 - 潜影盒交互保护，尽量避免刷物品、吞物品和嵌套放入问题
 - 管理模式独立背包、装备栏与状态切换
+- 维护模式：替换 MOTD、登录拦截、白名单放行和管理员拦截通知
 - Enderman 掉落方块控制
 - JEI 配方同步修复
 
-## 构建变体
+## 模块配置
 
-项目目前提供三个常用构建版本：
+项目现在默认构建一个完整插件，功能是否启用由 `plugins/EssentialsC/modules.yml` 控制。
 
-| 版本 | 产物名 | 说明 |
+| 模块 | 默认状态 | 说明 |
 | --- | --- | --- |
-| 标准版 | `EssentialsC-<version>.jar` | 默认版本，不包含 `mob-drops` 模块 |
+| `blocks` | 开启 | 便捷方块命令、`/essc blocks` 菜单、潜影盒快捷打开 |
-| 完整版 | `EssentialsC-all-<version>.jar` | 包含全部模块 |
+| `player` | 开启 | 飞行、夜视、发光、治疗、喂食、修复、帽子、自杀、隐身、查询玩家 |
-| 精简版 | `EssentialsC-lite-<version>.jar` | 仅排除 `blocks` 模块，保留 `mob-drops` |
+| `admin-mode` | 开启 | `/essc admin` 管理模式与独立状态保存 |
+| `tpsbar` | 开启 | 插件版 TPSBar，仍受 `config.yml` 中 `tpsbar.mode` 控制 |
+| `jei-sync` | 开启 | Fabric / NeoForge JEI 配方同步修复 |
+| `mob-drops` | 关闭 | 末影人掉落控制，默认关闭以保留过去标准版行为 |
+| `maintenance` | 开启 | 维护模式命令、MOTD 替换、登录拦截、白名单和拦截通知 |
 
-如果需要进一步裁剪模块，也可以使用自定义构建参数生成 `custom` 版本。
+修改模块开关后可先使用 `/essc reload` 刷新运行期服务与监听器状态。由于 Bukkit 命令表不适合在运行期完整热增删，若模块是在启动时关闭的，对应直连命令可能仍需重启后才会注册；通过 `/essc <子命令>` 入口通常可立即按新的模块状态执行。

+## 本地测试服
+
+项目包含两个本地测试服目录：
+
+| 测试服 | 端口 | 部署任务 | 启动脚本 |

+| Paper 1.21.11 | `25566` | `deployToPaper12111` | `test-server/paper-1.21.11/start.bat` |

+
+IDEA 运行配置会在启动测试服前自动执行对应部署任务。部署任务会替换 `EssentialsC*.jar`，并删除 `plugins/EssentialsC` 数据目录，以便测试新增默认配置和语言文本。
+
 ## 开发说明
 
 - 使用 `paperweight-userdev` 进行 Paper 开发
-- 运行时通过反射加载可选模块，避免裁剪版本因类缺失而启动失败
+- 使用 Paper Lifecycle Command API 注册命令，避免直接反射 Bukkit CommandMap
+- 运行时通过 `modules.yml` 控制模块加载，命令与监听器按模块状态注册
 - 发布流程基于 GitHub Actions 和 Gradle Wrapper
