+# MainMenuP0 Sample
+
+## 目的
+
+`MainMenuP0` 是 FlowScope 当前最小接入样例。它用于验证 P0/P1 Runtime 的推荐装配方式，而不是完整游戏模板。
+
+当前样例覆盖：
+
+- `GameBootstrap` 创建根 `Container`。
+- 注册 `IConfigProvider`、`IResourceService`、`ISaveService`、`IAudioService`、`UIManager`、`IUIPreloadService`、`IUIScreenNavigator`。
+- 使用 `RegisterTransient` 注册 `MainMenuFeature`。
+- 通过 `UIPreloadService` 预加载 `MainMenuPanel`。
+- 通过 `UIScreenNavigator` 打开主菜单面板。
+- 点击按钮修改 `PlayerData.Gold` 并刷新 UI。
+- `ShutdownAsync` 保存数据、关闭 `GameFlow` 并释放预加载资源。
+
+## 当前路径
+
+第一阶段仍保留在项目内开发模式：
+
+```text
+Assets/FlowScope/Samples/MainMenuP0
+```
+
+P2 第一阶段不把它移动到 `Samples~`，原因是当前 PlayMode 测试、场景引用、prefab 引用和 generated csproj 路径都依赖现有位置。等 P2 第二阶段开始本地 package 试迁移后，再把它作为候选包样例整理到：
+
+```text
+Samples~/MainMenuP0
+```
+
+## 如何运行
+
+在 Unity 中打开：
+
+```text
+Assets/FlowScope/Samples/MainMenuP0/Scenes/MainMenuP0.unity
+```
+
+进入 Play Mode 后，画面应显示主菜单面板、Gold 文本和递增按钮。
+
+## 验收点
+
+- 首次启动显示默认 Gold。
+- 点击按钮后 Gold 文本立即递增。
+- 调用 `ShutdownAsync` 后写入 `main-menu-player` 存档。
+- 再次启动后恢复上次保存的 Gold。
+- 关闭时释放预加载资源。
+- Console 不出现未预期 Error 或 Exception。
+
+## 自动化测试
+
+对应 PlayMode 测试位于：
+
+```text
+Assets/FlowScope/Tests/PlayMode/Samples/MainMenuP0Tests.cs
+```
+
+当前测试覆盖启动可见、按钮刷新、保存恢复、资源释放、启动任务可观察以及 shutdown 失败时的 best-effort cleanup。
+
+## 已知限制
+
+- 样例使用 `SampleResourceBackend`，不是 Addressables 真实资源验收。
+- 样例中有运行时 fallback UI，用于避免缺引用时完全不可运行；人工验收仍应优先检查场景和 prefab 引用是否完整。
+- 当前仍处于 `Assets/FlowScope` 开发模式，不代表 package sample 已完成迁移。

+# FlowScope 安装与最小接入
+
+日期：2026-05-26
+
+本文说明 FlowScope 在 P2 第一阶段面向使用者的安装路径、项目内开发模式，以及基于当前真实 API 的最小 Bootstrap 写法。当前仓库尚未完成标准 Unity Package 物理搬迁，package path 与 Git URL 方式是目标接入形态；项目内 `Assets/FlowScope` 开发模式是当前可用形态。
+
+## 安装方式
+
+### 本地 package path
+
+当后续完成标准包目录后，可在使用方 Unity 项目的 `Packages/manifest.json` 中使用本地路径：
+
+```json
+{
+  "dependencies": {
+    "com.flowscope.gamecore": "file:../FlowScope/Packages/com.flowscope.gamecore"
+  }
+}
+```
+
+适用场景：
+
+- 本机同时开发 FlowScope 与游戏项目。
+- 需要在包仓库中调试 Runtime、Addressables、Editor 或 Samples。
+- 希望由 Unity Package Manager 识别包结构与 `Samples~`。
+
+注意：P2 第一阶段当前仓库还没有 `Packages/com.flowscope.gamecore` 物理目录，因此此方式需要等第二阶段本地 package 试迁移完成后再用于实装验证。
+
+### Git URL
+
+当包目录与发布分支稳定后，可在 `Packages/manifest.json` 中使用 Git URL：
+
+```json
+{
+  "dependencies": {
+    "com.flowscope.gamecore": "<最终发布仓库 Git URL>?path=/Packages/com.flowscope.gamecore#v0.2.0"
+  }
+}
+```
+
+适用场景：
+
+- 使用方只消费稳定版本，不直接修改 FlowScope 源码。
+- 团队希望通过 tag 或固定 commit 控制接入版本。
+
+当前仓库 `origin` 仍带有旧项目名，不应直接写入对外安装文档。发布前需要由团队确认最终 FlowScope 包仓库地址；使用 Git URL 时应固定 tag 或 commit，避免使用浮动分支导致使用方项目在不同时间解析到不同代码。
+
+### 项目内 Assets 开发模式
+
+当前可用模式是将 FlowScope 放在 Unity 项目内：
+
+```text
+Assets/
+  FlowScope/
+    Runtime/
+    Addressables/
+    Samples/
+    Tests/
+```
+
+本仓库当前路径为：
+
+```text
+My project/Assets/FlowScope
+```
+
+适用场景：
+
+- P2 第一阶段继续验证 P0/P1 Runtime 行为。
+- 并行开发 Addressables 验收、Editor 诊断与 package 文档。
+- 在包迁移前保持 `MainMenuP0` 示例与测试路径稳定。
+
+使用此模式时，不需要在 `manifest.json` 中声明 `com.flowscope.gamecore`。仍需要确保项目已有当前代码依赖的包，例如 `com.cysharp.r3`、`com.unity.addressables` 与 `com.unity.ugui`。
+
+## 最小 Bootstrap 示例
+
+下面示例只使用当前代码中已经存在的 API 名称。示例使用 Addressables 作为资源后端，适合未来包接入；如果项目暂时没有 Addressables 资源，也可以参考 `MainMenuP0` 示例中的自定义 `IResourceBackend` 做本地验证。
+
+```csharp

+
+    private sealed class ExampleFeature : IFeature
+    {
+        private readonly IUIScreenNavigator _screenNavigator;
+
+        public ExampleFeature(IUIScreenNavigator screenNavigator)
+        {
+            _screenNavigator = screenNavigator;
+        }
+
+        public Task LoadAsync(FeatureContext context)
+        {
+            return Task.CompletedTask;
+        }
+
+        public Task EnterAsync(FeatureContext context)
+        {
+            return Task.CompletedTask;
+        }
+
+        public Task ExitAsync(FeatureContext context)
+        {
+            return Task.CompletedTask;
+        }
+
+        public void Dispose()
+        {
+        }
+    }
+}
+```
+
+接入要点：
+
+- `GameFlow.StartupAsync<TInitialFeature>(Container root, CancellationToken cancellationToken)` 会先解析并加载 `IConfigProvider`。
+- 初始 Feature 必须实现 `IFeature`，并能从 Feature scope 中解析；示例使用 `_root.RegisterTransient(_ => new ExampleFeature(screenNavigator))`。
+- 业务资源统一通过 `IResourceService` 或 `IResourceGroup` 加载，不直接在业务层调用 Addressables。
+- UI 层使用 `UIManager.RegisterLayer(...)` 建立层级，再由 `UIScreenNavigator` 或业务 Feature 打开面板。
+- Shutdown 时应调用 `GameFlow.ShutdownAsync(...)`，并释放 UI 预加载资源，例如 `_preloadService.ReleaseAll()`。
+
+## Addressables 接入说明
+
+使用 Addressables 时，推荐注册：
+
+```csharp
+IResourceService resources = new AddressablesResourceService(
+    new AddressablesResourceBackend());
+```
+
+这会把业务层依赖收敛到 `IResourceService`。`AddressablesResourceBackend` 只位于 Addressables 适配程序集，Runtime 不需要知道 Addressables 的存在。
+
+如果某个系统需要独立资源生命周期，应通过 `resources.CreateGroup()` 创建 `IResourceGroup`，让 Feature 的资源释放跟随 `FeatureContext.Resources.Dispose()`。
+
+## 常见误用
+
+- 不要让业务 Feature 直接调用 `UnityEngine.AddressableAssets.Addressables`；应通过 `IResourceService` 或 `IResourceGroup` 访问资源。
+- 不要把短生命周期对象注册成 `RegisterInstance` 或 `RegisterSingletonFactory`；临时对象优先使用 `RegisterTransient`，需要随 Feature 生命周期释放的对象放在 Feature scope。
+- 不要跳过 `GameFlow.ShutdownAsync(...)`；它负责退出当前 Feature、释放 Feature scope，并处置 root container。
+- 不要把 `UIScreenNavigator` 当成完整页面路由系统；它是当前 UI 导航辅助，不负责 URL、跨 Feature 页面恢复或全局路由。
+- 不要让 `FlowScope.Runtime` 反向依赖 Addressables、Editor、Samples 或 Tests。
+- 不要在没有注册 UI layer 的情况下打开面板；`UIManager.OpenAsync` 会要求面板声明的 layer 已经通过 `RegisterLayer` 注册。
+- 不要在未初始化 `AudioService.Initialize(IResourceService, AudioServiceConfig)` 前调用播放接口。
+- 不要假设 package path 与 Git URL 在 P2 第一阶段已经可安装；当前真实可用形态仍是项目内 `Assets/FlowScope` 开发模式。
+
+## 当前限制
+
+P2 第一阶段文档完成后，FlowScope 仍需要后续 worker 或阶段完成以下验证后，才能把 package 安装方式视为可交付：
+
+1. 建立真实 package 根目录与 `package.json`。
+2. 通过本地 package path 在干净 Unity 项目中验证安装。
+3. 验证 Git URL 安装与依赖解析。
+4. 将 `MainMenuP0` 从 `Assets/FlowScope/Samples` 整理为可导入 package sample。
+5. 在干净 Unity 项目中复验 Addressables 测试资源、settings 与 PlayMode 用例；主项目内的真实 load/release 验收记录已完成。
+6. 保持 generated csproj build 与 Unity Test Runner 记录为 0 error。

+# FlowScope Package 目标结构
+
+日期：2026-05-26
+
+本文说明 FlowScope P2 阶段的目标 Unity Package 目录形态，以及第一阶段暂不搬迁 `Assets/FlowScope` 的边界。本文只描述目标结构与迁移约束，不代表当前仓库已经完成物理搬迁。
+
+## 当前状态
+
+当前 FlowScope 仍处于项目内开发模式：
+
+```text
+My project/
+  Assets/
+    FlowScope/
+      Runtime/
+      Addressables/
+      Samples/
+      Tests/
+```
+
+当前尚未建立标准 Unity Package 根目录，未发现包级 `package.json`、`Samples~`、`Tests~`、`Documentation~` 目录。`MainMenuP0` 示例仍位于 `Assets/FlowScope/Samples/MainMenuP0`。
+
+## 目标包根目录
+
+目标包建议使用独立目录承载，例如：
+
+```text
+Packages/
+  com.flowscope.gamecore/
+    package.json
+    Runtime/
+    Addressables/
+    Editor/
+    Samples~/
+    Tests/
+    Documentation~/
+    README.md
+    CHANGELOG.md
+    LICENSE.md
+```
+
+目录职责如下：
+
+| 目录 | 职责 |
+| --- | --- |
+| `package.json` | Unity Package Manager 元数据，声明包名、显示名、版本、Unity 版本与依赖。 |
+| `Runtime/` | FlowScope 核心运行时代码，包括 Container、Feature、GameFlow、Resource、Config、Save、Audio、UI 等能力。 |
+| `Addressables/` | Addressables 适配层，提供 `AddressablesResourceBackend` 与 `AddressablesResourceService`。 |
+| `Editor/` | 只放编辑器诊断、检查、菜单入口等 Editor-only 内容，不承载运行时逻辑。 |
+| `Samples~/` | Package Manager 可导入示例，例如 `MainMenuP0`。示例可以依赖 Runtime 与所演示的适配包。 |
+| `Tests/` | 包内测试，按 EditMode 与 PlayMode 分层保留测试 asmdef。 |
+| `Documentation~/` | Package Manager 文档入口，包含安装、接入、诊断与示例说明。 |
+
+## package.json 建议形态
+
+目标包元数据建议保持最小可识别：
+
+```json
+{
+  "name": "com.flowscope.gamecore",
+  "displayName": "FlowScope Game Core",
+  "version": "0.2.0",
+  "unity": "2022.3",
+  "description": "A lightweight Unity game flow, resource, config, save, audio, and UI runtime foundation.",
+  "dependencies": {
+    "com.cysharp.r3": "https://github.com/Cysharp/R3.git?path=src/R3.Unity/Assets/R3.Unity#1.3.0",
+    "com.unity.addressables": "1.21.21",
+    "com.unity.ugui": "1.0.0"
+  }
+}
+```
+
+依赖说明：
+
+- `com.cysharp.r3` 是当前 `FlowScope.Runtime.asmdef` 直接引用 `R3.Unity` 的来源。
+- `com.unity.addressables` 只服务 `FlowScope.Addressables`，Runtime 不直接依赖 Addressables。
+- `com.unity.ugui` 服务当前 UI 与示例中的 `Canvas`、`Button`、`Text` 等 UGUI 类型。
+
+如果后续发布渠道不接受 Git URL 形式依赖，应在发布前改为团队确认过的 OpenUPM、内网 registry 或嵌入式依赖策略。
+
+## asmdef 依赖方向
+
+当前与目标结构都必须保持以下方向：
+
+```text
+FlowScope.Runtime
+  -> R3.Unity
+
+FlowScope.Addressables
+  -> FlowScope.Runtime
+  -> Unity.Addressables
+  -> Unity.ResourceManager
+
+FlowScope.Editor
+  -> FlowScope.Runtime
+  -> 需要诊断的编辑器程序集
+
+FlowScope.Samples.MainMenuP0
+  -> FlowScope.Runtime
+  -> R3.Unity
+
+FlowScope.Tests.EditMode / FlowScope.Tests.PlayMode
+  -> 被测程序集
+```
+
+禁止反向依赖：
+
+- `FlowScope.Runtime` 不依赖 `FlowScope.Addressables`。
+- `FlowScope.Runtime` 不依赖 `FlowScope.Editor`。
+- `FlowScope.Runtime` 不依赖 `FlowScope.Samples.*`。
+- `FlowScope.Runtime` 不依赖测试程序集。
+- Samples 不作为 Runtime 的依赖来源。
+
+`AddressablesResourceService` 当前命名空间位于 `FlowScope.Resources`，但文件处于 `Assets/FlowScope/Addressables` 并编译进 `FlowScope.Addressables` 程序集；迁移时应保留程序集边界，不应因为命名空间相同而把 Addressables 适配代码并回 Runtime。
+
+## 第一阶段暂不搬迁 Assets/FlowScope 的原因
+
+P2 第一阶段只建立分发边界、安装接入文档、Addressables 验收与最小 Editor 诊断入口，不做物理搬迁，原因如下：
+
+1. 当前 `Assets/FlowScope` 已承载 P0/P1 Runtime、Addressables、Samples、Tests 的稳定验证路径。
+2. `MainMenuP0` 示例、PlayMode 测试与 Unity 生成的 csproj 仍依赖当前 Asset 路径。
+3. 一次性移动 Runtime、Samples、Tests 会同时改变 asmdef 路径、资源路径、场景引用、prefab 引用与测试发现路径，容易把包结构问题和运行时回归混在一起。
+4. 第一阶段还有并行 worker 处理 Addressables 验收与 Editor 诊断；Package 文档 worker 不应覆盖或移动他们的文件。
+5. 先用文档锁定目标结构与依赖方向，可以让第二阶段本地 package 试迁移按批次验证，而不是一次性大搬迁。
+
+## 建议迁移顺序
+
+后续进入 P2 第二阶段时，建议按以下顺序迁移，每一步都保留独立验证记录：
+
+1. 创建 package 根目录与 `package.json`，先不移动 Runtime。
+2. 将 `Runtime/` 移入包目录并验证 `FlowScope.Runtime` 编译边界。
+3. 将 `Addressables/` 移入包目录并验证 `FlowScope.Addressables` 仍只依赖 Runtime 与 Unity Addressables。
+4. 将文档迁入 `Documentation~/` 或同步保留到仓库 `docs/`。
+5. 将 `MainMenuP0` 作为包示例迁入 `Samples~/MainMenuP0`，验证场景、prefab、配置与测试路径。
+6. 将 EditMode / PlayMode 测试整理进包内 `Tests/`，验证 Unity Test Runner 发现与执行。
+
+每一步完成前都应验证 generated csproj build、Unity Test Runner 和关键示例路径；如果某一步失败，应先回到该步骤修复，不继续叠加后续搬迁。

+# FlowScope Addressables 集成验收记录
+
+日期：2026-06-04
+
+## 验收目的
+
+本文用于补齐 P2 第一阶段的 Addressables 真实集成验收缺口。目标不是重新设计资源系统，而是确认当前 `FlowScope.Addressables.AddressablesResourceBackend` 能通过真实 Addressables key 完成加载、释放和错误诊断。
+
+## 项目配置
+
+已确认：
+
+- `My project/Packages/manifest.json` 包含 `com.unity.addressables`，当前版本为 `1.21.21`。
+- `My project/Assets/FlowScope/Addressables/FlowScope.Addressables.asmdef` 引用 `FlowScope.Runtime`、`Unity.Addressables`、`Unity.ResourceManager`。
+- `My project/Assets/FlowScope/Tests/PlayMode/FlowScope.Tests.PlayMode.asmdef` 引用 `FlowScope.Addressables`。
+- 当前项目已生成 `My project/Assets/AddressableAssetsData`。
+- `My project/ProjectSettings/EditorBuildSettings.asset` 已登记 Addressables settings config object。
+
+## 测试资源
+
+真实 Addressables 测试资源：
+
+- 路径：`Assets/FlowScope/Tests/PlayMode/Resources_moved/Fixtures/Addressables/FlowScopeAddressablesText.txt`
+- 内容：`FlowScope Addressables Acceptance`
+- GUID：`7e04733ce9dab74459592d3bd99fcafd`
+- Addressables group：`Default Local Group`
+- Addressables key：`FlowScope.Tests.Addressables.Text`
+- 资源类型：`TextAsset`
+
+`Default Local Group.asset` 中已确认存在：
+
+```yaml
+m_GUID: 7e04733ce9dab74459592d3bd99fcafd
+m_Address: FlowScope.Tests.Addressables.Text
+```
+
+## 自动化验收
+
+已在 `My project/Assets/FlowScope/Tests/PlayMode/Resources/AddressablesResourceBackendTests.cs` 补充真实 PlayMode 集成测试：
+
+- `LoadAsync_WithRealTextAssetKey_LoadsTextAsset`
+- `LoadAsync_WithMissingKey_ThrowsDiagnosticException`
+- `LoadAsync_WithMismatchedType_ThrowsDiagnosticException`
+
+覆盖范围：
+
+- `AddressablesResourceBackend.LoadAsync<TextAsset>` 能通过真实 key 加载真实 `TextAsset`。
+- `AddressablesResourceBackend.Release` 能释放已加载资源。
+- 缺失 key 会产生可捕获诊断异常，并包含缺失 key。
+- 类型不匹配会产生可捕获诊断异常，并包含 key 和请求类型。
+
+本轮同时修复了 `AddressablesResourceBackend.LoadAsync<T>` 的失败状态处理：当 Addressables handle 存在 `OperationException`、`Status` 不是 `Succeeded` 或 `Result` 为 `null` 时，backend 会抛出包含 key、请求类型和 backend 名称的 `InvalidOperationException`。
+
+## 验收结果
+
+用户已在 Unity Test Runner 中执行全量 EditMode / PlayMode，结果全绿。
+
+本轮针对 Addressables 集成用例的最终结果：
+
+| 项目 | 结果 | 证据 |
+| --- | --- | --- |
+| 真实 `LoadAsync<TextAsset>` | 通过 | `FlowScope.Tests.Addressables.Text` 加载真实 `TextAsset` |
+| `Release<TextAsset>` | 通过 | 成功释放已加载资源，未产生未处理日志 |
+| 缺失 key 诊断 | 通过 | `FlowScope.Tests.Addressables.Missing` 产生可捕获异常 |
+| 类型不匹配诊断 | 通过 | `TextAsset` key 以 `GameObject` 请求时产生可捕获异常 |
+| Unity Test Runner EditMode | 通过 | 用户反馈全量 EditMode 全绿 |
+| Unity Test Runner PlayMode | 通过 | 用户反馈全量 PlayMode 全绿 |
+
+## 剩余注意事项
+
+- 当前 Addressables 测试资源位于 `Resources_moved` 路径下；这是本轮真实验收的有效路径，但后续 package 迁移时应统一测试资源目录命名。
+- `Assets/FlowScope/Tests/PlayMode/Resources/Fixtures` 当前只剩空目录 meta，属于提交前清理候选。
+- 当前验收仍在主项目内完成；P2 后续 package 阶段还需要在干净 Unity 项目中验证本地 package path 或 Git URL 安装。
+
+## 结论
+
+P2 第一阶段的 Addressables 真实集成验收已完成。当前不再只是编译通过或人工步骤文档，而是已有真实 PlayMode 自动化测试覆盖成功加载、释放、缺失 key 和类型不匹配诊断。

+# FlowScope P2 第一阶段基线审查
+
+日期：2026-05-26
+
+## 审查目的
+
+本文用于锁定 P2 第一阶段执行边界。P2 第一阶段只推进 package 分发边界、安装接入文档、Addressables 真实验收、Editor 最小诊断入口和 MainMenuP0 样例说明，不重写 P0/P1 Runtime 生命周期，不扩大到完整包迁移或编辑器平台化。
+
+## 当前分支与工作树
+
+- 当前分支：`codex/pre-p2-architecture-fixes`
+- 本文创建前 `git status --short --branch` 未显示待提交文件；命令输出包含本机 `C:\Users\13999/.config/git/ignore` 权限 warning。
+- 本阶段提交信息必须使用中文。
+- 本阶段计划、审查、报告必须使用中文。
+
+## P0/P1 Runtime 基线
+
+当前 P0/P1 基线以 `docs/requirements/p0-requirements-set.md`、`docs/requirements/p1-production-hardening.md`、`docs/reviews/p1-completion-report.md` 和 `docs/guides/flowscope-runtime-usage.md` 为主要依据。
+
+已确认的实现状态：
+
+- `FlowScope.Runtime` 已包含 Container、Feature、GameFlow、Config、Save、Resource、Audio、UI、UIPreload、UIScreenNavigator 等 P0/P1 Runtime 能力。
+- `FlowScope.Runtime` 的 asmdef 只引用 `R3.Unity`，不直接引用 Addressables、Editor 或 Samples。
+- 资源系统已拆成 Runtime 核心 `ResourceService` + `IResourceBackend`，Addressables 适配位于独立 `FlowScope.Addressables` 程序集。
+- `UIPreloadService.Release<TPanel>()` 已包含 panel 级 in-flight invalidation，并有 `Release_WhenLoadInFlight_DoesNotCacheAndDisposesLoadedHandle` 测试覆盖；旧的第五轮审查中提到的该项中风险在当前代码中已收口。
+- `MainMenuP0` 仍在 `Assets/FlowScope/Samples/MainMenuP0`，尚未迁移到 `Samples~`。
+
+## Package / Editor 现状
+
+当前项目仍是 `Assets/FlowScope` 内开发模式，不是标准 Unity Package 目录。
+
+已确认缺口：
+
+- 当前未发现根级或包级 `package.json`。
+- 当前未发现 `Samples~`、`Tests~`、`Documentation~` 标准包目录。
+- 当前未发现 `Assets/FlowScope/Editor` 或 `FlowScope.Editor.asmdef`。
+- 当前还没有 package 安装说明覆盖本地 path、Git URL、项目内 Assets 开发模式三种路径。
+
+第一阶段边界：
+
+- 可以新增 package 结构方案文档和最小 package 元数据草案。
+- 可以新增最小 Editor 诊断入口。
+- 不在第一阶段直接搬迁 Runtime、Addressables、Samples 或 Tests。
+- 不删除 `Assets/FlowScope` 当前开发模式。
+
+## Addressables 验收缺口
+
+当前 `FlowScope.Addressables` 程序集存在：
+
+- `My project/Assets/FlowScope/Addressables/FlowScope.Addressables.asmdef`
+- `My project/Assets/FlowScope/Addressables/AddressablesResourceBackend.cs`
+- `My project/Assets/FlowScope/Addressables/AddressablesResourceService.cs`
+
+当前 `AddressablesResourceBackendTests` 只验证：
+
+- `Name_ReturnsAddressables`
+
+缺失的真实验收：
+
+- 使用真实 Addressables key 加载资源。
+- 验证 `AddressablesResourceBackend.LoadAsync<T>` 成功返回真实资源。
+- 验证 `Release<T>` 对已加载资源可重复进入释放流程且不产生业务层重复释放异常。
+- 验证缺失 key 或类型不匹配时，错误信息能定位 key、类型和 backend。
+- 如果自动化 PlayMode 准备成本过高，至少要有可重复人工验收步骤与结果记录。
+
+## 当前验证证据
+
+本轮已执行 generated csproj 编译验证：
+
+```powershell
+dotnet build "My project\FlowScope.Runtime.csproj" --no-restore
+dotnet build "My project\FlowScope.Tests.EditMode.csproj" --no-restore
+dotnet build "My project\FlowScope.Tests.PlayMode.csproj" --no-restore
+```
+
+结果：
+
+- `FlowScope.Runtime.csproj`：0 error。
+- `FlowScope.Tests.EditMode.csproj`：0 error。
+- `FlowScope.Tests.PlayMode.csproj`：0 error。
+- 存在 Unity generated csproj 常见引用冲突 warning，主要涉及 `System.Net.Http`、`System.Security.Cryptography.Algorithms`、`System.ComponentModel.Annotations`。
+
+未完成验证：
+
+- 本轮未执行 Unity Test Runner 全量 EditMode。
+- 本轮未执行 Unity Test Runner 全量 PlayMode。
+- 本轮未执行 MainMenuP0 人工场景验收。
+- 本轮未执行真实 Addressables load/release 验收。
+
+## P2 第一阶段并行任务边界
+
+### Task A：Package / 安装接入文档
+
+Owned files：
+
+- `docs/guides/flowscope-package-layout.md`

+Do not modify：
+
+- `My project/Assets/FlowScope/Runtime`
+- `My project/Assets/FlowScope/Addressables`
+- `My project/Assets/FlowScope/Editor`
+- `My project/Assets/FlowScope/Samples`
+- `My project/Assets/FlowScope/Tests`
+
+验收：
+
+- 文档说明标准 Unity Package 目标结构。
+- 文档说明第一阶段为什么暂不搬迁 Runtime/Samples/Tests。
+- 安装文档覆盖本地 package path、Git URL、Assets 开发模式。
+- Bootstrap 示例只使用当前真实 API 名称。
+
+### Task B：Addressables 真实验收

+Do not modify：
+
+- `My project/Assets/FlowScope/Runtime`
+- `My project/Assets/FlowScope/Addressables/AddressablesResourceBackend.cs`，除非测试证明当前实现存在真实 bug
+- Package 文档与 Editor 文件
+
+验收：
+
+- 优先提供自动化 PlayMode 测试证明真实资源 load/release。
+- 若自动化资源维护成本过高，必须提供可重复人工验收步骤、预期结果和未自动化原因。
+- `dotnet build "My project\FlowScope.Tests.PlayMode.csproj" --no-restore` 保持 0 error。
+
+### Task C：Editor 最小诊断入口

+Owned files：
+
+- `My project/Assets/FlowScope/Editor/FlowScope.Editor.asmdef`
+- `My project/Assets/FlowScope/Editor/FlowScopeDiagnosticsWindow.cs`
+- 必要 `.meta`
+- 可选：`docs/guides/flowscope-editor-diagnostics.md`
+
+Do not modify：
+
+- Runtime、Addressables、Samples、Tests 实现文件。
+- 不自动生成、移动、删除用户资源。
+
+验收：
+
+- Unity Editor 中有 `Tools/FlowScope/Diagnostics` 菜单入口。
+- 窗口只检查并输出状态，不自动修复。
+- 检查 Addressables package、Runtime asmdef、Addressables asmdef、MainMenuP0 关键场景和 prefab 是否存在。
+- generated csproj 编译保持 0 error。
+
+## 第一阶段完成 Gate
+
+P2 第一阶段完成前必须满足：
+
+1. `FlowScope.Runtime.csproj`、`FlowScope.Tests.EditMode.csproj`、`FlowScope.Tests.PlayMode.csproj` generated build 均为 0 error。
+2. Unity Test Runner 全量 EditMode / PlayMode 至少有明确执行记录；若无法执行，必须记录原因。
+3. Addressables adapter 有真实集成验收记录，不再只靠 `Name_ReturnsAddressables`。
+4. 新增 package/editor 内容不破坏 `Assets/FlowScope` 当前开发模式。
+5. 文档说明安装、接入、验证、已知限制和后续迁移边界。
+6. 所有提交信息使用中文。
+
+## 第一阶段之后
+
+第一阶段完成后进入 P2 第二阶段：本地 package 试迁移。
+
+第二阶段才开始创建真正 package 目录雏形并用本地 path 在干净 Unity 项目验证安装。Runtime、Addressables、Samples、Tests 的物理迁移应分批进行，不应在第一阶段一次性搬迁。

+# FlowScope P2 第一阶段完成报告
+
+日期：2026-06-04
+
+## 范围
+
+本阶段根据 `docs/requirements/p2-package-editor-requirements.md` 执行第一轮 P2 准备工作。范围限定为：
+
+- 锁定 P0/P1 当前基线。
+- 建立 package 目标结构与迁移边界文档。
+- 编写安装与最小接入文档。
+- 补 Addressables 真实验收入口。
+- 添加最小 Editor 诊断入口。
+- 整理 MainMenuP0 样例说明。
+
+本阶段没有重写 P0/P1 Runtime 生命周期，没有搬迁 `Assets/FlowScope`，没有创建正式 package 根目录。Addressables 项目设置由用户准备测试资源时生成，本轮仅接入测试、修复 backend 失败诊断并记录验收结果。
+
+## 已完成
+
+### 1. 基线审查
+
+新增：
+
+- `docs/reviews/p2-phase1-baseline-audit.md`
+
+内容包括：
+
+- 当前分支与工作树状态。
+- P0/P1 Runtime、Addressables、Samples、Tests 的现状。
+- Package / Editor 缺口。
+- Addressables 真实验收缺口。
+- P2 第一阶段并行任务边界。
+- 第一阶段完成 Gate 和下一阶段方向。
+
+### 2. Package 结构与安装文档
+
+新增：
+
+- `docs/guides/flowscope-package-layout.md`
+- `docs/guides/flowscope-installation.md`
+
+已覆盖：
+
+- 目标 package 结构：`package.json`、`Runtime`、`Addressables`、`Editor`、`Samples~`、`Tests`、`Documentation~`。
+- 第一阶段暂不搬迁 `Assets/FlowScope` 的原因。
+- asmdef 依赖方向和禁止反向依赖。
+- 本地 package path、Git URL、项目内 Assets 开发模式。
+- 基于当前真实 API 的最小 Bootstrap 示例。
+- 常见误用与当前限制。
+
+### 3. Addressables 验收入口
+
+新增：
+
+- `docs/reviews/addressables-integration-acceptance.md`
+
+结论：
+
+- 当前项目有 `com.unity.addressables` 和 `FlowScope.Addressables` asmdef。
+- 当前项目已有 `Assets/AddressableAssetsData`、默认 Addressables settings、`Default Local Group` 和可复用测试 key。
+- 已新增真实 PlayMode 自动化验收，覆盖真实 `TextAsset` 加载、释放、缺失 key 诊断和类型不匹配诊断。
+
+剩余缺口：
+
+- 当前 Addressables 测试资源路径为 `Assets/FlowScope/Tests/PlayMode/Resources_moved/Fixtures/Addressables/FlowScopeAddressablesText.txt`，后续 package 迁移时应统一测试资源目录命名。
+- `Assets/FlowScope/Tests/PlayMode/Resources/Fixtures` 当前只剩空目录 meta，属于提交前清理候选。
+
+### 4. Editor 最小诊断入口
+
+新增：
+
+- `My project/Assets/FlowScope/Editor.meta`
+- `My project/Assets/FlowScope/Editor/FlowScope.Editor.asmdef`
+- `My project/Assets/FlowScope/Editor/FlowScope.Editor.asmdef.meta`
+- `My project/Assets/FlowScope/Editor/FlowScopeDiagnosticsWindow.cs`
+- `My project/Assets/FlowScope/Editor/FlowScopeDiagnosticsWindow.cs.meta`
+
+能力：
+
+- 菜单入口：`Tools/FlowScope/Diagnostics`。
+- 只读检查，不自动生成、移动、删除或修复用户资源。
+- 检查 `com.unity.addressables` package、Runtime asmdef、Addressables asmdef、MainMenuP0 scene、MainMenuPanel prefab。
+- Addressables package 状态通过 `UnityEditor.PackageManager.Client.List(true)` 异步刷新，不阻塞 Editor。
+
+### 5. MainMenuP0 样例说明
+
+新增：
+
+- `My project/Assets/FlowScope/Samples/MainMenuP0/README.md`
+- `My project/Assets/FlowScope/Samples/MainMenuP0/README.md.meta`
+
+内容包括：
+
+- 样例目的。
+- 当前仍保留在 `Assets/FlowScope/Samples/MainMenuP0` 的原因。
+- 后续迁移到 `Samples~/MainMenuP0` 的候选路径。
+- 运行方式、验收点、自动化测试位置和已知限制。
+
+## 验证结果
+
+### Unity batchmode 导入 / 编译

+```
+
+结果：
+
+- Unity 导入新增 Editor 文件。

+- `FlowScope.Runtime.csproj`：0 error。
+- `FlowScope.Tests.EditMode.csproj`：0 error。
+- `FlowScope.Tests.PlayMode.csproj`：0 error。
+- 仍有 Unity generated csproj 既有引用冲突 warning，主要涉及 `System.Net.Http`、`System.Security.Cryptography.Algorithms`、`System.ComponentModel.Annotations`、`System.Threading.Tasks.Extensions`。
+
+### Unity Test Runner
+
+已执行：
+
+- 全量 EditMode。
+- 全量 PlayMode。
+
+结果：
+
+- 用户反馈全量 EditMode / PlayMode 全绿。
+- `AddressablesResourceBackendTests` 已覆盖真实 Addressables key：`FlowScope.Tests.Addressables.Text`。
+- 缺失 key 和类型不匹配路径已通过可捕获 backend 诊断异常验收。
+
+### 静态检查
+
+已执行：
+
+```powershell
+rg -n "<占位词扫描表达式>" <本阶段新增文档与 Editor 脚本>
+git diff --check
+```
+
+结果：
+
+- 未发现占位词命中。
+- `git diff --check` 无 whitespace error。
+
+## 未完成 Gate
+
+以下事项不在本阶段内完成，但必须在 P2 后续阶段继续追踪：
+
+1. 尚未创建正式 package 根目录和 `package.json` 文件。
+2. 尚未在干净 Unity 项目中验证本地 package path 或 Git URL 安装。
+3. 尚未实际打开 `Tools/FlowScope/Diagnostics` 做人工 UI 检查。
+4. Addressables 测试资源目录命名仍需在 package 迁移前统一。
+
+## 下一阶段建议
+
+进入 P2 第二阶段：本地 package 试迁移。
+
+建议顺序：
+
+1. 创建 `Packages/com.flowscope.gamecore` 和最小 `package.json`。
+2. 先复制或镜像 Runtime 到 package 目录，不删除 `Assets/FlowScope`。
+3. 在当前项目和一个干净 Unity 项目中验证本地 package path。
+4. 整理 Addressables 测试资源目录，再迁移 package 内 Tests。
+5. 再考虑 `Samples~/MainMenuP0` 和 Tests 的分批迁移。
