 本文件记录 `ShrinkEventBus` 在当前工作区中的包内变更。
 
+## [2.2.3] - 2026-10-03
+
+- Unity 可独立通过 Git URL 安装，必装依赖仅保留 UniTask 和官方 Mono.Cecil。
+- Shared Runtime 与 Shared CodeGen 改为可选集成，由包版本宏自动启用。
+- 内置独立特性订阅织入器，支持实例、静态、UniTask 和 MonoBehaviour 生命周期绑定；安装 Shared CodeGen 后由共享生成器接管。
+- Unity 主线程调度契约改为 `IShrinkEventBusMainThreadDispatcher`；共享接口通过 `ShrinkSharedMainThreadDispatcher` 适配，.NET/Godot 接口不变。
+- 独立验证工程取消私有 registry 要求，增加外部消费程序集的生成绑定测试及可选调度适配测试。
+
 ## [2.0.1] - 2026-08-28

-# ShrinkEventBus 2.0
+# ShrinkEventBus
 
 ShrinkEventBus 2.0 是面向 Unity、普通 C# 宿主和 Entities/Burst 生产端的统一事件总线。运行时只有一种事件模型、一个订阅入口和一组发布 API；不同 Bus 只表达生命周期、所有权与调度策略。
 
 Godot 和普通 .NET 项目安装 `ShrinkSDK.EventBus`；可打包源码位于 `DotNet~`，订阅注册由 `ShrinkSDK.CodeGen` 在构建时织入。
 
+## Unity 安装
+
+要求 Unity 2022.3 或更新版本。在 Package Manager 中使用 **Add package from git URL**，依次安装：
+
+```text
+https://github.com/Cysharp/UniTask.git?path=src/UniTask/Assets/Plugins/UniTask#7c0f199fe0d3fc528024488ccd671e6c7b27745b
+https://github.com/cneicy/ShrinkEventBus.git
+```
+
+第一个地址固定 UniTask 2.5.10。Mono.Cecil 1.11.4 由 Unity 官方 registry 自动解析；无需配置 ShrinkSDK registry。需要锁定 EventBus 版本时，在 Git URL 后添加 `#<commit>`。
+
+### 可选 ShrinkSDK 集成
+
+| 已安装的共享包 | 行为 |
+|---|---|
+| 无 | 使用包内调度接口和 EventBus 专用 ILPostProcessor |
+| Runtime Abstractions 0.1.0+ | 额外启用共享主线程调度器适配程序集 |
+| Shared CodeGen 0.2.1+ | 停用包内织入，交给共享 CodeGen 统一生成订阅 |
+| 两者都有 | 同时启用上述两项集成 |
+
+通过 asmdef `versionDefines` 自动生成 `SHRINK_EVENTBUS_HAS_SHARED_RUNTIME` 和 `SHRINK_EVENTBUS_HAS_SHARED_CODEGEN`，不需要手工设置宏。两个共享包由完整工程自行安装，EventBus 不再强制拉取它们。
+
+Unity 自定义调度器现在实现 `IShrinkEventBusMainThreadDispatcher`。已有的共享 `IShrinkMainThreadDispatcher` 实现使用以下适配方式：
+
+```csharp
+using ShrinkEventBus;
+using ShrinkEventBus.Integration;
+
+ShrinkEventBusRuntime.ConfigureMainThreadDispatcher(
+    new ShrinkSharedMainThreadDispatcher(sharedDispatcher));
+```
+
+使用自定义 asmdef 的业务程序集还需引用 `ShrinkEventBus.Integration.Runtime`。默认 UniTask PlayerLoop 调度无需配置；请在创建需要自定义调度的 Bus 前完成配置。此调整只影响 Unity，现有 .NET/Godot 配置接口保持不变。
+
+### 最小使用示例
+
+业务 asmdef 引用 `ShrinkEventBus.Runtime`，使用 UniTask 时再引用 `UniTask`。无需 `partial`、反射注册或手工生成绑定：
+
+```csharp
+using ShrinkEventBus;
+using UnityEngine;
+
+public readonly struct PlayerJoined : IShrinkEvent { }
+
+[ShrinkEventSubscriber]
+public sealed class PlayerHandlers
+{
+    [ShrinkSubscribe]
+    private void OnJoined(PlayerJoined value) => Debug.Log("Player joined");
+}
+
+// 在 Unity 主线程执行；binding 应由实际宿主持有并在生命周期结束时释放。
+using (var binding = EventBus.Attach(new PlayerHandlers()))
+{
+    EventBus.Post(new PlayerJoined());
+}
+```
+
+包内 `Development~/UnityProject` 是独立验证工程，包含外部消费程序集的同步/异步订阅测试。使用 Unity Test Runner 运行 EditMode 和 PlayMode 测试；包本身的测试通过 manifest 的 `testables` 开启。
+
 ## 核心契约

 - 外部 Mod DLL 必须携带生成合同；没有合同的生产 DLL 不自动反射注册。
 - Editor 诊断是可选观察层，不参与正式无诊断热路径。
 
-架构审计与来源说明见 `Docs/JustAnyProjectArchitectureAudit.md` 和根目录 `DESIGN.md`。
+Unity 独立安装不包含 Entities/Burst 适配包；需要时由宿主额外安装。
