# ArchitectureScope Container Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** 按 `docs/specs/architecture-scope-container-implementation-spec.md` 实现统一的 `ArchitectureScope` / FlowScope Container / Scope Tree，并替换当前 `RootContext + FeatureScope` 试验入口。

**Architecture:** 第一阶段只做核心 Scope 与容器边界：`FlowScope.Create()` 创建 Root，Root / Feature / Child 都通过同一个 `IArchitectureScope` 表达。保留现有 `FlowScope.Container.Container` 中已经成立的父子查找、局部覆盖、`PerScope()`、Dispose 子树等能力，在其上新增 Core 接口与 `ArchitectureScope` 包装/约束层；旧 `FlowScope.Composition` 不继续扩展，最后删除或降级。

**Tech Stack:** Unity C#，NUnit EditMode tests，现有 `FlowScope.Runtime.asmdef` / `FlowScope.Tests.EditMode.asmdef`，验证优先使用 `dotnet build --no-restore`。

---

## 执行边界

本计划只实现以下内容：

- `FlowScope.Create()` 根入口。
- `IArchitectureScope` / `IScopeInfo` / `IFeature` / `IRegistrationBuilder`。
- `ArchitectureScope` 统一 Scope 节点。
- Register / Resolve / CreateScope / CreateFeature / Dispose 规则。
- 旧 Composition 测试中仍有价值的 Root 服务、Feature 隔离、命名注册用例迁移到 Core 测试。
- 移除或降级旧 `RootContext + FeatureScope + Command/Query` 试验入口。

本计划不实现：

- Command / Query / Event。
- 完整 MVC / MVVM。
- UI Panel 生命周期统一接管。
- 自动扫描 Feature。
- 资源、存档、音频、UI 模块改造。

执行前必须先确认当前工作树已有改动，不能覆盖用户已有修改：

```powershell
git status --short
git diff -- "My project/Assets/FlowScope/Runtime/Container/Container.cs"
git diff -- "My project/Assets/FlowScope/Runtime/Container/ContainerRegistration.cs"
git diff -- "My project/Assets/FlowScope/Tests/EditMode/Container/ContainerTests.cs"
```

如果这些文件已有未合并改动，执行者必须在当前改动基础上续写，不得 `git restore` 或重写文件。

## 文件结构

### 新增 Runtime Core 文件

- Create: `My project/Assets/FlowScope/Runtime/Core/FlowScope.cs`
  - 静态入口，创建 Root Scope。
- Create: `My project/Assets/FlowScope/Runtime/Core/IArchitectureScope.cs`
  - 统一 Scope 主接口。
- Create: `My project/Assets/FlowScope/Runtime/Core/IScopeInfo.cs`
  - 只读 Scope 元信息接口。
- Create: `My project/Assets/FlowScope/Runtime/Core/IFeature.cs`
  - Feature 安装接口。
- Create: `My project/Assets/FlowScope/Runtime/Core/IRegistrationBuilder.cs`
  - Core 层注册生命周期 builder 接口。
- Create: `My project/Assets/FlowScope/Runtime/Core/Container/ArchitectureScope.cs`
  - 统一 Scope 节点实现。
- Create: `My project/Assets/FlowScope/Runtime/Core/Container/ScopeExceptions.cs`
  - 核心 Scope 异常类型。

### 修改现有 Container 文件

- Modify: `My project/Assets/FlowScope/Runtime/Container/Container.cs`
  - 暴露 `ParentInfo` / `Path` / `IsDisposed` 所需的最小只读能力。
  - 增加同级重名 Scope 检查。
  - 确保 `CreateScope(string name)` 空名失败。
  - 保持注册只写当前 Container，不改变父级。
- Modify: `My project/Assets/FlowScope/Runtime/Container/ContainerRegistration.cs`
  - 将 `ServiceLifetime.Scoped` 命名调整为 `PerScope`，或在 Core 层适配为 `PerScope`。
  - 保持 `PerScope` 缓存到 Resolve 发起 Scope 的语义。

### 新增 Core EditMode 测试

- Create: `My project/Assets/FlowScope/Tests/EditMode/Core/ArchitectureScopeRegistrationTests.cs`
- Create: `My project/Assets/FlowScope/Tests/EditMode/Core/ArchitectureScopeResolveTests.cs`
- Create: `My project/Assets/FlowScope/Tests/EditMode/Core/ArchitectureScopeFeatureTests.cs`
- Create: `My project/Assets/FlowScope/Tests/EditMode/Core/ArchitectureScopeDisposeTests.cs`

### 删除或降级旧 Composition

- Delete or quarantine: `My project/Assets/FlowScope/Runtime/Composition/CompositionContracts.cs`
- Delete or quarantine: `My project/Assets/FlowScope/Runtime/Composition/FlowScopeApp.cs`
- Delete or migrate: `My project/Assets/FlowScope/Tests/EditMode/Composition/CompositionTests.cs`

如果执行时选择“降级”而不是删除，必须放到 `FlowScope.LegacyComposition` 命名空间，并且不得被新 Core 测试依赖。

## Task 1: 新增 Core 接口与根入口

**Files:**

- Create: `My project/Assets/FlowScope/Runtime/Core/IScopeInfo.cs`
- Create: `My project/Assets/FlowScope/Runtime/Core/IRegistrationBuilder.cs`
- Create: `My project/Assets/FlowScope/Runtime/Core/IFeature.cs`
- Create: `My project/Assets/FlowScope/Runtime/Core/IArchitectureScope.cs`
- Create: `My project/Assets/FlowScope/Runtime/Core/FlowScope.cs`
- Test: `My project/Assets/FlowScope/Tests/EditMode/Core/ArchitectureScopeRegistrationTests.cs`

- [ ] **Step 1: 创建目录和 Unity meta**

执行者在 Unity 项目中创建目录：

```text
My project/Assets/FlowScope/Runtime/Core/
My project/Assets/FlowScope/Runtime/Core/Container/
My project/Assets/FlowScope/Tests/EditMode/Core/
```

如果通过文件系统创建，执行后打开 Unity 或保持后续生成 `.meta` 被纳入同一提交。不要手写 `.meta`。

- [ ] **Step 2: 先写 Root 入口测试**

在 `ArchitectureScopeRegistrationTests.cs` 写入：

```csharp
using NUnit.Framework;

namespace FlowScope.Tests.EditMode.Core
{
    public sealed class ArchitectureScopeRegistrationTests
    {
        [Test]
        public void Create_ReturnsRootArchitectureScope()
        {
            using var root = FlowScope.FlowScope.Create();

            Assert.That(root.Name, Is.EqualTo("Root"));
            Assert.That(root.Parent, Is.Null);
            Assert.That(root.Path, Is.EqualTo("Root"));
            Assert.That(root.IsDisposed, Is.False);
        }
    }
}
```

- [ ] **Step 3: 运行测试确认失败**

```powershell
dotnet build "My project/FlowScope.Tests.EditMode.csproj" --no-restore
```

Expected: FAIL，缺少 `FlowScope.FlowScope` / `IArchitectureScope`。

- [ ] **Step 4: 新增接口代码**

`IScopeInfo.cs`：

```csharp
namespace FlowScope
{
    public interface IScopeInfo
    {
        string Name { get; }
        IScopeInfo Parent { get; }
        string Path { get; }
        bool IsDisposed { get; }
    }
}
```

`IRegistrationBuilder.cs`：

```csharp
namespace FlowScope
{
    public interface IRegistrationBuilder
    {
        void AsSingleton();
        void PerScope();
        void AsTransient();
    }
}
```

`IFeature.cs`：

```csharp
namespace FlowScope
{
    public interface IFeature
    {
        void Install(IArchitectureScope scope);
    }
}
```

`IArchitectureScope.cs`：

```csharp
using System;

namespace FlowScope
{
    public interface IArchitectureScope : IScopeInfo, IDisposable
    {
        IArchitectureScope CreateScope(string name);
        IArchitectureScope CreateFeature<TFeature>() where TFeature : IFeature, new();
        IArchitectureScope CreateFeature<TFeature>(string name) where TFeature : IFeature, new();

        IRegistrationBuilder Register<TImplementation>();
        IRegistrationBuilder Register<TImplementation>(string name);
        IRegistrationBuilder Register<TService, TImplementation>() where TImplementation : TService;
        IRegistrationBuilder Register<TService, TImplementation>(string name) where TImplementation : TService;

        void RegisterInstance<TService>(TService instance);
        void RegisterInstance<TService>(TService instance, string name);

        TService Resolve<TService>();
        TService Resolve<TService>(string name);
        bool TryResolve<TService>(out TService value);
        bool TryResolve<TService>(out TService value, string name);
    }
}
```

- [ ] **Step 5: 新增临时可编译入口**

`FlowScope.cs`：

```csharp
using FlowScope.Core.Container;

namespace FlowScope
{
    public static class FlowScope
    {
        public static IArchitectureScope Create()
        {
            return Create("Root");
        }

        public static IArchitectureScope Create(string rootName)
        {
            return new ArchitectureScope(rootName);
        }
    }
}
```

- [ ] **Step 6: 暂存后续实现需要的空壳**

`ArchitectureScope.cs` 先写可编译空壳，但未实现行为：

```csharp
using System;

namespace FlowScope.Core.Container
{
    internal sealed class ArchitectureScope : IArchitectureScope
    {
        public ArchitectureScope(string name)
        {
            Name = name;
            Path = name;
        }

        public string Name { get; }
        public IScopeInfo Parent => null;
        public string Path { get; }
        public bool IsDisposed { get; private set; }

        public IArchitectureScope CreateScope(string name) => throw new NotImplementedException();
        public IArchitectureScope CreateFeature<TFeature>() where TFeature : IFeature, new() => throw new NotImplementedException();
        public IArchitectureScope CreateFeature<TFeature>(string name) where TFeature : IFeature, new() => throw new NotImplementedException();
        public IRegistrationBuilder Register<TImplementation>() => throw new NotImplementedException();
        public IRegistrationBuilder Register<TImplementation>(string name) => throw new NotImplementedException();
        public IRegistrationBuilder Register<TService, TImplementation>() where TImplementation : TService => throw new NotImplementedException();
        public IRegistrationBuilder Register<TService, TImplementation>(string name) where TImplementation : TService => throw new NotImplementedException();
        public void RegisterInstance<TService>(TService instance) => throw new NotImplementedException();
        public void RegisterInstance<TService>(TService instance, string name) => throw new NotImplementedException();
        public TService Resolve<TService>() => throw new NotImplementedException();
        public TService Resolve<TService>(string name) => throw new NotImplementedException();
        public bool TryResolve<TService>(out TService value, string name) => throw new NotImplementedException();
        public bool TryResolve<TService>(out TService value) => throw new NotImplementedException();
        public void Dispose() => IsDisposed = true;
    }
}
```

- [ ] **Step 7: 运行测试确认入口测试通过**

```powershell
dotnet build "My project/FlowScope.Runtime.csproj" --no-restore
dotnet build "My project/FlowScope.Tests.EditMode.csproj" --no-restore
```

Expected: PASS build。此时只有 Root 入口行为成立。

**建议提交点:** `feat: 新增 ArchitectureScope 核心接口入口`

## Task 2: 实现 Register 只写当前 Scope

**Files:**

- Modify: `My project/Assets/FlowScope/Runtime/Core/Container/ArchitectureScope.cs`
- Create: `My project/Assets/FlowScope/Runtime/Core/Container/RegistrationBuilderAdapter.cs`
- Test: `My project/Assets/FlowScope/Tests/EditMode/Core/ArchitectureScopeRegistrationTests.cs`

- [ ] **Step 1: 增加 Register 测试**

向 `ArchitectureScopeRegistrationTests.cs` 增加：

```csharp
[Test]
public void Register_WritesOnlyCurrentScope()
{
    using var root = FlowScope.FlowScope.Create();
    using var child = root.CreateScope("Child");

    root.Register<IService, RootService>().AsSingleton();
    child.Register<IService, ChildService>().AsSingleton();

    Assert.That(root.Resolve<IService>(), Is.TypeOf<RootService>());
    Assert.That(child.Resolve<IService>(), Is.TypeOf<ChildService>());
}

[Test]
public void Register_DuplicateKeyInSameScopeThrows()
{
    using var root = FlowScope.FlowScope.Create();
    root.Register<IService, RootService>().AsSingleton();

    Assert.Throws<InvalidOperationException>(() =>
        root.Register<IService, ChildService>().AsSingleton());
}

private interface IService { }
private sealed class RootService : IService { }
private sealed class ChildService : IService { }
```

- [ ] **Step 2: 运行测试确认失败**

```powershell
dotnet build "My project/FlowScope.Tests.EditMode.csproj" --no-restore
```

Expected: FAIL，`CreateScope` / `Register` / `Resolve` 未实现。

- [ ] **Step 3: 用现有 Container 实现 Register 代理**

`RegistrationBuilderAdapter.cs`：

```csharp
using FlowScope.Container;

namespace FlowScope.Core.Container
{
    internal sealed class RegistrationBuilderAdapter : IRegistrationBuilder
    {
        private readonly ContainerRegistrationBuilder _inner;

        public RegistrationBuilderAdapter(ContainerRegistrationBuilder inner)
        {
            _inner = inner;
        }

        public void AsSingleton() => _inner.AsSingleton();
        public void PerScope() => _inner.PerScope();
        public void AsTransient() => _inner.AsTransient();
    }
}
```

在 `ArchitectureScope` 中持有现有 Container：

```csharp
private readonly FlowScope.Container.Container _container;

public IRegistrationBuilder Register<TImplementation>()
{
    ThrowIfDisposed();
    return new RegistrationBuilderAdapter(_container.Register<TImplementation>());
}

public IRegistrationBuilder Register<TImplementation>(string name)
{
    ThrowIfDisposed();
    return new RegistrationBuilderAdapter(_container.Register<TImplementation>(name));
}

public IRegistrationBuilder Register<TService, TImplementation>()
    where TImplementation : TService
{
    ThrowIfDisposed();
    return new RegistrationBuilderAdapter(_container.Register<TService, TImplementation>());
}

public IRegistrationBuilder Register<TService, TImplementation>(string name)
    where TImplementation : TService
{
    ThrowIfDisposed();
    return new RegistrationBuilderAdapter(_container.Register<TService, TImplementation>(name));
}

public void RegisterInstance<TService>(TService instance)
{
    RegisterInstance(instance, null);
}

public void RegisterInstance<TService>(TService instance, string name)
{
    ThrowIfDisposed();
    _container.RegisterInstance(instance, name);
}
```

- [ ] **Step 4: 实现 Resolve 代理**

```csharp
public TService Resolve<TService>()
{
    ThrowIfDisposed();
    return _container.Resolve<TService>();
}

public TService Resolve<TService>(string name)
{
    ThrowIfDisposed();
    return _container.Resolve<TService>(name);
}

public bool TryResolve<TService>(out TService value)
{
    ThrowIfDisposed();
    return _container.TryResolve(out value);
}

public bool TryResolve<TService>(out TService value, string name)
{
    ThrowIfDisposed();
    return _container.TryResolve(out value, name);
}
```

- [ ] **Step 5: 运行测试确认通过**

```powershell
dotnet build "My project/FlowScope.Tests.EditMode.csproj" --no-restore
```

Expected: PASS build，新增 Register 测试通过。

**建议提交点:** `feat: 实现 ArchitectureScope 注册解析入口`

## Task 3: 实现 Scope Tree 与 Path

**Files:**

- Modify: `My project/Assets/FlowScope/Runtime/Core/Container/ArchitectureScope.cs`
- Modify: `My project/Assets/FlowScope/Runtime/Container/Container.cs`
- Test: `My project/Assets/FlowScope/Tests/EditMode/Core/ArchitectureScopeResolveTests.cs`

- [ ] **Step 1: 写 Scope Tree 测试**

`ArchitectureScopeResolveTests.cs`：

```csharp
using NUnit.Framework;

namespace FlowScope.Tests.EditMode.Core
{
    public sealed class ArchitectureScopeResolveTests
    {
        [Test]
        public void CreateScope_CreatesChildWithParentAndPath()
        {
            using var root = FlowScope.FlowScope.Create();
            using var feature = root.CreateScope("BossFightFeature");
            using var child = feature.CreateScope("RevivePanel");

            Assert.That(feature.Parent, Is.SameAs(root));
            Assert.That(child.Parent, Is.SameAs(feature));
            Assert.That(feature.Path, Is.EqualTo("Root/BossFightFeature"));
            Assert.That(child.Path, Is.EqualTo("Root/BossFightFeature/RevivePanel"));
        }

        [Test]
        public void CreateScope_DuplicateSiblingNameThrows()
        {
            using var root = FlowScope.FlowScope.Create();
            using var first = root.CreateScope("BossFightFeature");

            Assert.Throws<InvalidOperationException>(() => root.CreateScope("BossFightFeature"));
        }
    }
}
```

- [ ] **Step 2: 运行测试确认失败**

```powershell
dotnet build "My project/FlowScope.Tests.EditMode.csproj" --no-restore
```

Expected: FAIL，`CreateScope` 未实现或未检查重名。

- [ ] **Step 3: 在 ArchitectureScope 内维护子 Scope**

实现要点：

```csharp
private readonly ArchitectureScope _parent;
private readonly List<ArchitectureScope> _children = new List<ArchitectureScope>();

public IScopeInfo Parent => _parent;

public IArchitectureScope CreateScope(string name)
{
    ThrowIfDisposed();
    if (string.IsNullOrWhiteSpace(name))
    {
        throw new ArgumentException("Scope name cannot be empty.", nameof(name));
    }

    if (_children.Exists(child => !child.IsDisposed && child.Name == name))
    {
        throw new InvalidOperationException($"Scope '{name}' already exists under '{Path}'.");
    }

    var childContainer = _container.CreateScope(name);
    var child = new ArchitectureScope(name, this, childContainer);
    _children.Add(child);
    return child;
}
```

构造函数需要变成：

```csharp
public ArchitectureScope(string name)
    : this(name, null, new FlowScope.Container.Container())
{
}

private ArchitectureScope(string name, ArchitectureScope parent, FlowScope.Container.Container container)
{
    if (string.IsNullOrWhiteSpace(name))
    {
        throw new ArgumentException("Scope name cannot be empty.", nameof(name));
    }

    Name = name;
    _parent = parent;
    _container = container;
    Path = parent == null ? name : $"{parent.Path}/{name}";
}
```

- [ ] **Step 4: 确保 Dispose 从父节点移除**

在 `Dispose` 中释放子 Scope 后：

```csharp
_parent?._children.Remove(this);
```

- [ ] **Step 5: 运行测试确认通过**

```powershell
dotnet build "My project/FlowScope.Tests.EditMode.csproj" --no-restore
```

Expected: PASS build，Scope Tree / Path 测试通过。

**建议提交点:** `feat: 实现 ArchitectureScope 树结构`

## Task 4: 固化 Resolve 父级查找与子级覆盖

**Files:**

- Modify: `My project/Assets/FlowScope/Runtime/Core/Container/ArchitectureScope.cs`
- Modify: `My project/Assets/FlowScope/Runtime/Container/Container.cs`
- Test: `My project/Assets/FlowScope/Tests/EditMode/Core/ArchitectureScopeResolveTests.cs`

- [ ] **Step 1: 增加父级查找与覆盖测试**

```csharp
[Test]
public void Resolve_FallsBackToParentWhenCurrentMissing()
{
    using var root = FlowScope.FlowScope.Create();
    using var feature = root.CreateScope("BossFightFeature");

    var clock = new RootClock(42);
    root.RegisterInstance<IRootClock>(clock);

    Assert.That(feature.Resolve<IRootClock>(), Is.SameAs(clock));
}

[Test]
public void Resolve_ChildRegistrationOverridesParent()
{
    using var root = FlowScope.FlowScope.Create();
    using var feature = root.CreateScope("BossFightFeature");

    root.Register<IRewardService, GlobalRewardService>().AsSingleton();
    feature.Register<IRewardService, BossRewardService>().AsSingleton();

    Assert.That(root.Resolve<IRewardService>(), Is.TypeOf<GlobalRewardService>());
    Assert.That(feature.Resolve<IRewardService>(), Is.TypeOf<BossRewardService>());
}

private interface IRootClock { int Value { get; } }
private sealed class RootClock : IRootClock
{
    public RootClock(int value) => Value = value;
    public int Value { get; }
}

private interface IRewardService { }
private sealed class GlobalRewardService : IRewardService { }
private sealed class BossRewardService : IRewardService { }
```

- [ ] **Step 2: 运行测试**

```powershell
dotnet build "My project/FlowScope.Tests.EditMode.csproj" --no-restore
```

Expected: PASS。现有 `Container.TryFindRegistration` 已支持向父查找；如果失败，修复 Container 父子链传递。

- [ ] **Step 3: 增加 TryResolve 语义测试**

```csharp
[Test]
public void TryResolve_MissingRegistrationReturnsFalse()
{
    using var root = FlowScope.FlowScope.Create();

    Assert.That(root.TryResolve<IRewardService>(out var value), Is.False);
    Assert.That(value, Is.Null);
}
```

- [ ] **Step 4: 确保构造异常不被 TryResolve 吞掉**

```csharp
[Test]
public void TryResolve_ConstructorFailureThrows()
{
    using var root = FlowScope.FlowScope.Create();
    root.Register<BrokenService>().AsTransient();

    Assert.Throws<InvalidOperationException>(() =>
        root.TryResolve<BrokenService>(out _));
}

private sealed class BrokenService
{
    public BrokenService()
    {
        throw new InvalidOperationException("broken");
    }
}
```

Expected: PASS。若现有反射调用把异常包成 `TargetInvocationException`，按当前实际行为断言外层异常，但不要返回 false。

**建议提交点:** `test: 固化 Scope 解析查找语义`

## Task 5: 固化生命周期语义

**Files:**

- Modify: `My project/Assets/FlowScope/Runtime/Container/ContainerRegistration.cs`
- Modify: `My project/Assets/FlowScope/Runtime/Container/Container.cs`
- Test: `My project/Assets/FlowScope/Tests/EditMode/Core/ArchitectureScopeDisposeTests.cs`

- [ ] **Step 1: 写生命周期测试**

`ArchitectureScopeDisposeTests.cs`：

```csharp
using NUnit.Framework;

namespace FlowScope.Tests.EditMode.Core
{
    public sealed class ArchitectureScopeDisposeTests
    {
        [Test]
        public void Singleton_FromParentIsSharedByChildrenAndDisposedByParent()
        {
            using var root = FlowScope.FlowScope.Create();
            var first = root.CreateScope("First");
            var second = root.CreateScope("Second");

            root.Register<IDisposableService, DisposableService>().AsSingleton();

            var rootInstance = root.Resolve<IDisposableService>();
            Assert.That(first.Resolve<IDisposableService>(), Is.SameAs(rootInstance));
            Assert.That(second.Resolve<IDisposableService>(), Is.SameAs(rootInstance));

            first.Dispose();
            Assert.That(rootInstance.IsDisposed, Is.False);

            root.Dispose();
            Assert.That(rootInstance.IsDisposed, Is.True);
        }

        [Test]
        public void PerScope_FromParentCreatesDifferentInstancesPerChildScope()
        {
            using var root = FlowScope.FlowScope.Create();
            var first = root.CreateScope("First");
            var second = root.CreateScope("Second");

            root.Register<IDisposableService, DisposableService>().PerScope();

            var firstInstance = first.Resolve<IDisposableService>();
            var secondInstance = second.Resolve<IDisposableService>();

            Assert.That(first.Resolve<IDisposableService>(), Is.SameAs(firstInstance));
            Assert.That(second.Resolve<IDisposableService>(), Is.SameAs(secondInstance));
            Assert.That(firstInstance, Is.Not.SameAs(secondInstance));

            first.Dispose();
            Assert.That(firstInstance.IsDisposed, Is.True);
            Assert.That(secondInstance.IsDisposed, Is.False);
        }

        private interface IDisposableService
        {
            bool IsDisposed { get; }
        }

        private sealed class DisposableService : IDisposableService, System.IDisposable
        {
            public bool IsDisposed { get; private set; }
            public void Dispose() => IsDisposed = true;
        }
    }
}
```

- [ ] **Step 2: 运行测试**

```powershell
dotnet build "My project/FlowScope.Tests.EditMode.csproj" --no-restore
```

Expected: PASS。现有 Container 大概率已满足；如果失败，修复 `ContainerRegistration.ResolveScoped(requester)` 的缓存归属。

- [ ] **Step 3: 写 Dispose 顺序与幂等测试**

```csharp
[Test]
public void Dispose_ParentDisposesChildrenBeforeOwnInstancesAndIsIdempotent()
{
    DisposeRecorder.Order.Clear();
    var root = FlowScope.FlowScope.Create();
    var child = root.CreateScope("Child");

    root.Register<ITracked, RootTracked>().AsSingleton();
    child.Register<IChildTracked, ChildTracked>().AsSingleton();

    root.Resolve<ITracked>();
    child.Resolve<IChildTracked>();

    root.Dispose();
    root.Dispose();

    CollectionAssert.AreEqual(new[] { "child", "root" }, DisposeRecorder.Order);
}

private interface ITracked { }
private interface IChildTracked { }

private static class DisposeRecorder
{
    public static readonly System.Collections.Generic.List<string> Order =
        new System.Collections.Generic.List<string>();
}

private sealed class RootTracked : ITracked, System.IDisposable
{
    public void Dispose() => DisposeRecorder.Order.Add("root");
}

private sealed class ChildTracked : IChildTracked, System.IDisposable
{
    public void Dispose() => DisposeRecorder.Order.Add("child");
}
```

- [ ] **Step 4: 明确 Instance 不释放外部实例**

保留或迁移现有 `ContainerTests.RegisterInstance_Resolve_ReturnsSameInstanceAndDoesNotDisposeExternalInstance`，在 Core 测试中也覆盖：

```csharp
[Test]
public void RegisterInstance_DefaultDoesNotDisposeExternalInstance()
{
    var root = FlowScope.FlowScope.Create();
    var service = new DisposableService();

    root.RegisterInstance<IDisposableService>(service);
    root.Dispose();

    Assert.That(service.IsDisposed, Is.False);
}
```

**建议提交点:** `test: 固化 ArchitectureScope 生命周期语义`

## Task 6: 实现 CreateFeature 自动创建与安装

**Files:**

- Modify: `My project/Assets/FlowScope/Runtime/Core/Container/ArchitectureScope.cs`
- Test: `My project/Assets/FlowScope/Tests/EditMode/Core/ArchitectureScopeFeatureTests.cs`

- [ ] **Step 1: 写 CreateFeature 测试**

`ArchitectureScopeFeatureTests.cs`：

```csharp
using System;
using NUnit.Framework;

namespace FlowScope.Tests.EditMode.Core
{
    public sealed class ArchitectureScopeFeatureTests
    {
        [Test]
        public void CreateFeature_UsesFeatureTypeNameAndCallsInstall()
        {
            using var root = FlowScope.FlowScope.Create();

            using var feature = root.CreateFeature<BossFightFeature>();

            Assert.That(feature.Name, Is.EqualTo(nameof(BossFightFeature)));
            Assert.That(feature.Path, Is.EqualTo("Root/BossFightFeature"));
            Assert.That(feature.Resolve<BossFightModel>(), Is.Not.Null);
        }

        [Test]
        public void CreateFeature_WithNameUsesExplicitName()
        {
            using var root = FlowScope.FlowScope.Create();

            using var feature = root.CreateFeature<BossFightFeature>("BossFight");

            Assert.That(feature.Name, Is.EqualTo("BossFight"));
            Assert.That(feature.Resolve<BossFightModel>(), Is.Not.Null);
        }

        private sealed class BossFightFeature : IFeature
        {
            public void Install(IArchitectureScope scope)
            {
                scope.Register<BossFightModel>().PerScope();
            }
        }

        private sealed class BossFightModel { }
    }
}
```

- [ ] **Step 2: 实现 CreateFeature**

在 `ArchitectureScope` 中：

```csharp
public IArchitectureScope CreateFeature<TFeature>()
    where TFeature : IFeature, new()
{
    return CreateFeature<TFeature>(typeof(TFeature).Name);
}

public IArchitectureScope CreateFeature<TFeature>(string name)
    where TFeature : IFeature, new()
{
    ThrowIfDisposed();
    var featureScope = (ArchitectureScope)CreateScope(name);
    try
    {
        var feature = new TFeature();
        feature.Install(featureScope);
        return featureScope;
    }
    catch
    {
        featureScope.Dispose();
        throw;
    }
}
```

- [ ] **Step 3: 写 Install 失败清理测试**

```csharp
[Test]
public void CreateFeature_WhenInstallFailsDisposesCreatedScope()
{
    using var root = FlowScope.FlowScope.Create();

    Assert.Throws<InvalidOperationException>(() => root.CreateFeature<BrokenFeature>());

    using var feature = root.CreateFeature<BossFightFeature>(nameof(BrokenFeature));
    Assert.That(feature.Name, Is.EqualTo(nameof(BrokenFeature)));
}

private sealed class BrokenFeature : IFeature
{
    public void Install(IArchitectureScope scope)
    {
        throw new InvalidOperationException("install failed");
    }
}
```

这个测试证明失败 Scope 已从父级移除，否则同名创建会失败。

- [ ] **Step 4: 运行测试确认通过**

```powershell
dotnet build "My project/FlowScope.Tests.EditMode.csproj" --no-restore
```

Expected: PASS build，CreateFeature 默认名、显式名、Install、失败清理全部通过。

**建议提交点:** `feat: 实现 CreateFeature 自动安装`

## Task 7: 迁移有价值的旧 Composition 用例

**Files:**

- Modify: `My project/Assets/FlowScope/Tests/EditMode/Core/ArchitectureScopeFeatureTests.cs`
- Modify: `My project/Assets/FlowScope/Tests/EditMode/Core/ArchitectureScopeResolveTests.cs`
- Delete or quarantine: `My project/Assets/FlowScope/Tests/EditMode/Composition/CompositionTests.cs`

- [ ] **Step 1: 迁移 Root 服务可被 Feature Resolve**

新增测试：

```csharp
[Test]
public void FeatureScope_CanResolveRootServices()
{
    using var root = FlowScope.FlowScope.Create();
    var clock = new RootClock(10);
    root.RegisterInstance<IRootClock>(clock);

    using var feature = root.CreateFeature<ClockFeature>();

    Assert.That(feature.Resolve<IRootClock>(), Is.SameAs(clock));
    Assert.That(feature.Resolve<ClockModel>().Value, Is.EqualTo(10));
}

private interface IRootClock { int Value { get; } }
private sealed class RootClock : IRootClock
{
    public RootClock(int value) => Value = value;
    public int Value { get; }
}

private sealed class ClockFeature : IFeature
{
    public void Install(IArchitectureScope scope)
    {
        scope.Register<ClockModel>().PerScope();
    }
}

private sealed class ClockModel
{
    public ClockModel(IRootClock clock) => Value = clock.Value;
    public int Value { get; }
}
```

- [ ] **Step 2: 迁移 Feature 级服务隔离**

新增测试：

```csharp
[Test]
public void TwoFeatureScopes_DoNotSharePerScopeFeatureServices()
{
    using var root = FlowScope.FlowScope.Create();
    root.Register<IFeatureService, FeatureService>().PerScope();

    using var first = root.CreateFeature<EmptyFeature>("FirstActivity");
    using var second = root.CreateFeature<EmptyFeature>("SecondActivity");

    Assert.That(first.Resolve<IFeatureService>(), Is.SameAs(first.Resolve<IFeatureService>()));
    Assert.That(first.Resolve<IFeatureService>(), Is.Not.SameAs(second.Resolve<IFeatureService>()));
}

private interface IFeatureService { }
private sealed class FeatureService : IFeatureService { }
private sealed class EmptyFeature : IFeature
{
    public void Install(IArchitectureScope scope) { }
}
```

- [ ] **Step 3: 迁移命名注册**

新增测试：

```csharp
[Test]
public void NamedRegistration_ResolvesByTypeAndNameFromFeature()
{
    using var root = FlowScope.FlowScope.Create();
    root.Register<IRewardService, BossRewardService>("boss").PerScope();
    root.Register<IRewardService, ScratchRewardService>("scratch").PerScope();

    using var boss = root.CreateFeature<EmptyFeature>("BossFight");
    using var scratch = root.CreateFeature<EmptyFeature>("ScratchTicket");

    Assert.That(boss.Resolve<IRewardService>("boss"), Is.TypeOf<BossRewardService>());
    Assert.That(scratch.Resolve<IRewardService>("scratch"), Is.TypeOf<ScratchRewardService>());
    Assert.That(boss.Resolve<IRewardService>("boss"), Is.SameAs(boss.Resolve<IRewardService>("boss")));
    Assert.That(boss.Resolve<IRewardService>("boss"), Is.Not.SameAs(scratch.Resolve<IRewardService>("boss")));
}

private interface IRewardService { }
private sealed class BossRewardService : IRewardService { }
private sealed class ScratchRewardService : IRewardService { }
```

- [ ] **Step 4: 不迁移 Command / Query 测试**

旧测试 `FeatureScope_CommandAndQueryOperateOnScopedArchitecture` 不迁移。原因：spec 明确第一阶段不进入 Command / Query / Event。

- [ ] **Step 5: 运行测试**

```powershell
dotnet build "My project/FlowScope.Tests.EditMode.csproj" --no-restore
```

Expected: PASS build。

**建议提交点:** `test: 迁移 Composition 核心用例到 ArchitectureScope`

## Task 8: 删除或隔离旧 Composition 试验线

**Files:**

- Delete or quarantine: `My project/Assets/FlowScope/Runtime/Composition/CompositionContracts.cs`
- Delete or quarantine: `My project/Assets/FlowScope/Runtime/Composition/FlowScopeApp.cs`
- Delete or quarantine: `My project/Assets/FlowScope/Tests/EditMode/Composition/CompositionTests.cs`

- [ ] **Step 1: 查找旧 Composition 引用**

```powershell
rg -n "FlowScope\.Composition|IRootContext|IFeatureScope|ICommandContext|IQueryContext|CreateFeatureScope|FlowScopeApp" "My project/Assets/FlowScope"
```

Expected: 只剩 Runtime/Composition 与 Tests/EditMode/Composition 自身引用。

- [ ] **Step 2: 删除旧 Runtime/Composition 文件**

如果没有外部引用，执行：

```powershell
git rm "My project/Assets/FlowScope/Runtime/Composition/CompositionContracts.cs" "My project/Assets/FlowScope/Runtime/Composition/CompositionContracts.cs.meta" "My project/Assets/FlowScope/Runtime/Composition/FlowScopeApp.cs" "My project/Assets/FlowScope/Runtime/Composition/FlowScopeApp.cs.meta"
```

如果 Unity `.meta` 尚未生成或未跟踪，按实际文件列表只删除存在的路径。

- [ ] **Step 3: 删除旧 Composition 测试**

```powershell
git rm "My project/Assets/FlowScope/Tests/EditMode/Composition/CompositionTests.cs" "My project/Assets/FlowScope/Tests/EditMode/Composition/CompositionTests.cs.meta"
```

- [ ] **Step 4: 删除空目录 meta**

如果目录为空，删除对应目录和 `.meta`：

```powershell
git rm "My project/Assets/FlowScope/Runtime/Composition.meta" "My project/Assets/FlowScope/Tests/EditMode/Composition.meta"
```

如果目录里仍有迁移期 adapter，不删除目录。

- [ ] **Step 5: 再次确认旧入口不存在**

```powershell
rg -n "FlowScope\.Composition|IRootContext|IFeatureScope|ICommandContext|IQueryContext|CreateFeatureScope|FlowScopeApp" "My project/Assets/FlowScope"
```

Expected: exit code 1，表示没有匹配；这里 exit code 1 是通过条件。

**建议提交点:** `refactor: 移除旧 Composition 试验入口`

## Task 9: 总体验证与验收

**Files:**

- Verify: `My project/FlowScope.Runtime.csproj`
- Verify: `My project/FlowScope.Tests.EditMode.csproj`
- Verify: `docs/specs/architecture-scope-container-implementation-spec.md`

- [ ] **Step 1: 编译 Runtime**

```powershell
dotnet build "My project/FlowScope.Runtime.csproj" --no-restore
```

Expected: Build succeeded。

- [ ] **Step 2: 编译 EditMode Tests**

```powershell
dotnet build "My project/FlowScope.Tests.EditMode.csproj" --no-restore
```

Expected: Build succeeded。

- [ ] **Step 3: 验证负向边界**

```powershell
rg -n "RootContext|FeatureScope|IRootContext|IFeatureScope|ICommandContext|IQueryContext|CreateFeatureScope|FlowScopeApp" "My project/Assets/FlowScope/Runtime"
```

Expected: exit code 1，表示 Runtime 中不再存在旧试验入口。

- [ ] **Step 4: 验证第一阶段没有引入后续模块**

```powershell
rg -n "CommandContext|QueryContext|EventContext|UseMvvm|UseMvc|UIPanelLifecycle" "My project/Assets/FlowScope/Runtime/Core"
```

Expected: exit code 1，表示 Core 没有提前引入 Command / Query / Event / MVC / MVVM / UI Panel 生命周期接管。

- [ ] **Step 5: 格式与空白检查**

```powershell
git diff --check
```

Expected: 无输出。

- [ ] **Step 6: 检查 staged 范围**

如果用户要求提交，执行者只应 stage 本计划相关文件：

```powershell
git add "My project/Assets/FlowScope/Runtime/Core" "My project/Assets/FlowScope/Tests/EditMode/Core" "My project/Assets/FlowScope/Runtime/Container/Container.cs" "My project/Assets/FlowScope/Runtime/Container/ContainerRegistration.cs"
```

如果旧 Composition 文件被删除，再额外 stage 精确删除路径。不要 broad add 整个项目。

**建议最终提交信息:** `feat: 实现统一 ArchitectureScope 容器树`

## 自检清单

- [ ] `FlowScope.Create()` 返回 Root `IArchitectureScope`。
- [ ] Root / Feature / Child 都是同一种 `IArchitectureScope`。
- [ ] `CreateFeature<TFeature>()` 默认名为 `typeof(TFeature).Name`。
- [ ] `CreateFeature<TFeature>(name)` 自动创建 Scope 并调用 `Install`。
- [ ] 任意 Scope 可 Register，但只写自己。
- [ ] Resolve 从当前 Scope 开始，找不到向 Parent 查找。
- [ ] 子 Scope 覆盖父 Scope 时不修改父 Scope。
- [ ] Singleton 由注册所在 Scope 持有。
- [ ] PerScope 由 Resolve 发起 Scope 持有。
- [ ] Transient 每次创建新实例，并按最终规则释放。
- [ ] RegisterInstance 默认不释放外部实例。
- [ ] 子 Scope Dispose 不释放父 Scope 对象。
- [ ] 父 Scope Dispose 释放所有子 Scope。
- [ ] Dispose 幂等。
- [ ] 旧 `RootContext + FeatureScope + Command/Query` 不再是新核心入口。
- [ ] 第一阶段没有实现 Command / Query / Event、完整 MVC/MVVM、UI Panel 生命周期统一接管。
