+# GFramework.Cqrs.Benchmarks
+
+该模块承载 `GFramework.Cqrs` 的独立性能基准工程，用于持续比较运行时 dispatch、publish、cold-start 与后续 generator / pipeline 收口的成本变化。
+
+## 目的
+
+- 为 `GFramework.Cqrs` 建立独立于 NUnit 集成测试的 BenchmarkDotNet 基线
+- 参考 `ai-libs/Mediator/benchmarks` 的场景组织方式，逐步补齐 request、notification、stream 与初始化成本对比
+- 为后续吸收 `Mediator` 的 dispatch 设计、fixture 组织和对比矩阵提供可重复验证入口
+
+## 当前内容
+
+- `Program.cs`
+  - benchmark 命令行入口
+- `Messaging/Fixture.cs`
+  - 运行前输出并校验场景配置
+- `Messaging/RequestBenchmarks.cs`
+  - direct handler、`GFramework.Cqrs` runtime 与 `MediatR` 的 request steady-state dispatch 对比
+- `Messaging/RequestPipelineBenchmarks.cs`
+  - `0 / 1 / 4` 个 pipeline 行为下，direct handler、`GFramework.Cqrs` runtime 与 `MediatR` 的 request steady-state dispatch 对比
+- `Messaging/RequestStartupBenchmarks.cs`
+  - `Initialization` 与 `ColdStart` 两组 request startup 成本对比，补齐与 `Mediator` comparison benchmark 更接近的 startup 维度
+- `Messaging/RequestInvokerBenchmarks.cs`
+  - direct handler、`GFramework.Cqrs` reflection runtime、handwritten generated-invoker runtime 与 `MediatR` 的 request steady-state dispatch 对比
+- `Messaging/StreamInvokerBenchmarks.cs`
+  - direct handler、`GFramework.Cqrs` reflection runtime、handwritten generated-invoker runtime 与 `MediatR` 的 stream 完整枚举对比
+- `Messaging/NotificationBenchmarks.cs`
+  - `GFramework.Cqrs` runtime 与 `MediatR` 的单处理器 notification publish 对比
+- `Messaging/StreamingBenchmarks.cs`
+  - direct handler、`GFramework.Cqrs` runtime 与 `MediatR` 的 stream request 完整枚举对比
+
+## 最小使用方式
+
+```bash
+dotnet run --project GFramework.Cqrs.Benchmarks/GFramework.Cqrs.Benchmarks.csproj -c Release
+```
+
+也可以通过 `BenchmarkDotNet` 过滤器只运行某一类场景。
+
+## 后续扩展方向
+
+- generated invoker provider 与纯反射 dispatch 对比
+- generated stream invoker provider 与纯反射建流对比
+- registration / service lifetime 矩阵
+- request / stream 的真实 source-generator 产物与 handwritten generated provider 对照

+### 阶段：开放对象关键字边界收口（AI-FIRST-CONFIG-RP-003）
+
+- 已在 Runtime、Source Generator 与 VS Code Tooling 三端统一收紧开放对象关键字边界
+- 本轮不是扩 JSON Schema 能力，而是避免某一端静默接受会重新打开对象形状的 schema：
+  - 当前继续接受 `additionalProperties: false` 作为显式闭合对象提醒
+  - `patternProperties`、`propertyNames`、`unevaluatedProperties` 当前改为三端直接失败
+- reader-facing docs 也已同步更新，避免采用文档继续把这类关键字描述成“也许工具没做但运行时可能支持”的灰区
+
+### 关键决定
+
+- `additionalProperties: false` 仍是唯一共享支持的开放对象相关关键字形状
+- 任何会重新引入动态字段集的开放对象关键字，都视为当前主线之外的设计，而不是后续工具增强项
+- 本轮继续保持主线为 `C# Runtime + Source Generator + Consumer DX`，没有把工作重心切回复杂表单或宿主验证

 ## 当前活跃事实
 
-- 当前分支对应 `PR #323`，状态为 `OPEN`
-- latest-head review 仍以 `ai-plan` 恢复文档收敛为主要待闭环项；代码与测试侧的本地有效问题已收敛
+- 当前分支对应 `PR #326`，状态为 `OPEN`
+- latest-head review 现仍有少量 open thread，但本地复核后，仍成立的问题已收敛到 benchmark 对照公平性、workflow 输入安全性与 active 文档压缩
+- benchmark 场景现统一通过 `BenchmarkHostFactory` 构建最小宿主：GFramework 侧在 runtime 分发前显式 `Freeze()` 容器，MediatR 侧只扫描当前场景需要的 handler / behavior 类型
+- `RequestStartupBenchmarks` 已恢复 `ColdStart_GFrameworkCqrs` 结果产出，不再命中 `No CQRS request handler registered`
+- 已新增手动触发的 benchmark workflow；默认只验证 benchmark 项目 Release build，只有显式提供过滤器时才执行 BenchmarkDotNet 运行；过滤器输入现通过环境变量传入 shell，避免 workflow_dispatch 输入直接插值到命令行
 - 远端 `CTRF` 最新汇总为 `2274/2274` passed
 - `MegaLinter` 当前只暴露 `dotnet-format` 的 `Restore operation failed` 环境噪音，尚未提供本地仍成立的文件级格式诊断
 
 ## 当前风险
 
 - 顶层 `GFramework.sln` / `GFramework.csproj` 在 WSL 下仍可能受 Windows NuGet fallback 配置影响，完整 solution 级验证成本高于模块级验证
+- `RequestStartupBenchmarks` 为了量化真正的单次 cold-start，引入了 `InvocationCount=1` / `UnrollFactor=1` 的专用 job；该配置会触发 BenchmarkDotNet 的 `MinIterationTime` 提示，后续若要做稳定基线比较，还需要决定是否引入批量外层循环或自定义 cold-start harness
 - 仓库内部仍保留旧 `Command` / `Query` API、`LegacyICqrsRuntime` alias 与部分历史命名语义，后续若不继续分批收口，容易混淆“对外替代已完成”与“内部收口未完成”
 - 若继续扩大 generated invoker 覆盖面，需要持续区分“可静态表达的合同”与 `PreciseReflectedRegistrationSpec` 等仍需保守回退的场景

 # CQRS 重写迁移追踪
 
+## 2026-05-06
+
+### 阶段：benchmark 对照宿主收敛与 startup cold-start 恢复（CQRS-REWRITE-RP-090）
+
+- 使用 `$gframework-pr-review` 拉取 `PR #326` latest-head review 后，主线程确认仍有效的 benchmark 反馈集中在三类问题：
+  - `RequestBenchmarks` 的 GFramework / MediatR handler 生命周期不对齐
+  - `RequestStartupBenchmarks` 把容器构建、程序集扫描范围和缓存清理阶段混在一起，导致 cold-start 对照不公平
+  - benchmark 工程里的 `MicrosoftDiContainer` 多处以 `ImplementationType` 方式注册 handler，但未在 runtime 分发前 `Freeze()`，首次真实解析路径存在隐藏失败风险
+- 本轮本地复核的关键根因：
+  - `MicrosoftDiContainer.Get(Type)` 在未冻结时只读取 `ImplementationInstance`，不会实例化 `ImplementationType`
+  - `ColdStart_GFrameworkCqrs` 清空 dispatcher 静态缓存后，首次发送必须走真实 handler 解析，因此会稳定触发 `No CQRS request handler registered`
+  - 多个 benchmark 同时采用“手工 MediatR 注册 + `RegisterServicesFromAssembly(...)` 全程序集扫描”，容易把无关 handler / behavior 一并纳入对照，且存在重复注册漂移
+- 本轮决策：
+  - 新增 `Messaging/BenchmarkHostFactory.cs`，统一 benchmark 最小宿主构建规则
+  - GFramework benchmark 宿主统一先注册再 `Freeze()`，保证 steady-state 与 cold-start 都走真实可解析容器
+  - MediatR benchmark 宿主统一通过 `TypeEvaluator` 限制到当前场景所需 handler / behavior 类型，保留正常 `AddMediatR` 组装路径，同时移除全程序集扫描噪音
+  - `RequestStartupBenchmarks` 采用专用 `ColdStart` job，设置 `InvocationCount=1` 与 `WithUnrollFactor(1)`，并把 dispatcher cache reset 放到 `IterationSetup`
+- 已修改的 benchmark 范围：
+  - `RequestBenchmarks`
+  - `RequestPipelineBenchmarks`
+  - `RequestStartupBenchmarks`
+  - `StreamingBenchmarks`
+  - `NotificationBenchmarks`
+  - `RequestInvokerBenchmarks`
+  - `StreamInvokerBenchmarks`
+- 结果：
+  - `ColdStart_GFrameworkCqrs` 已恢复出有效结果，不再出现 `No CQRS request handler registered`
+  - `RequestBenchmarks`、`RequestStartupBenchmarks` 在本地均可实际运行
+  - `RequestStartupBenchmarks` 目前仍会收到 BenchmarkDotNet 对单次 cold-start 场景的 `MinIterationTime` 提示；这是测量形状带来的工具提示，不再是运行级失败
+

+  - 备注：steady-state request 对照可正常运行，未再触发 MediatR 重复注册或 GFramework 首次解析失败
+
+### 阶段：PR #326 review 收尾补丁（CQRS-REWRITE-RP-090）
+
+- 再次使用 `$gframework-pr-review` 复核 `PR #326` latest-head open threads 后，主线程确认本轮仍成立且适合在当前 PR 内收敛的问题集中在四类：
+  - `.github/workflows/benchmark.yml` 的 `benchmark_filter` 直接插值到 shell，存在 workflow_dispatch 输入注入风险
+  - `RequestInvokerBenchmarks` 与 `StreamInvokerBenchmarks` 的 MediatR handler 生命周期仍为 `Singleton`，与 GFramework 反射 / generated 路径的 transient 语义不一致
+  - `RequestPipelineBenchmarks` 未在场景切换前后清理 dispatcher 缓存，且四个空 pipeline behavior 类型仍使用非法的分号类声明
+  - `ai-plan/public/cqrs-rewrite` active 文档仍保留旧失败结论与重复日期标题，和“active 入口只保留最新权威恢复点”的约束不一致
+- 本轮刻意未扩展处理的 review：
+  - `MicrosoftDiContainer` 的释放契约建议会扩大到核心 Ioc 接口与全仓库生命周期语义，不适合作为 benchmark review 顺手改动
+  - `RequestStartupBenchmarks` 的“手工单点注册 vs 受限程序集扫描”差异目前属于有意保留的最小宿主模型，代码注释已明确该设计边界
+- 已修改：
+  - `.github/workflows/benchmark.yml`
+  - `GFramework.Cqrs.Benchmarks/Messaging/RequestInvokerBenchmarks.cs`
+  - `GFramework.Cqrs.Benchmarks/Messaging/RequestPipelineBenchmarks.cs`
+  - `GFramework.Cqrs.Benchmarks/Messaging/StreamInvokerBenchmarks.cs`
+  - `ai-plan/public/cqrs-rewrite/todos/cqrs-rewrite-migration-tracking.md`
+  - `ai-plan/public/cqrs-rewrite/traces/cqrs-rewrite-migration-trace.md`
+- 预期结果：
+  - 手动 benchmark workflow 的过滤器输入不再直接参与 shell 解析
+  - request / stream invoker 三路对照的 handler 生命周期重新回到同一基线
+  - request pipeline benchmark 在 `0 / 1 / 4` 场景切换时不再复用旧 dispatcher cache
+  - active tracking / trace 更符合 boot 恢复入口所要求的“只保留最新权威结论”形状

+
+- 使用 `$gframework-batch-boot 50` 继续 `feat/cqrs-optimization` 的 CQRS 收口批次
+- 批次目标：在 branch diff 相对 `origin/main` 接近 `50` 个文件前，继续补齐低风险的 generator runtime contract / emission 回归
+- 本轮基线选择：
+  - `origin/main a8c6c11e`，committer date `2026-05-05 13:14:24 +0800`
+  - `main a8c6c11e`，committer date `2026-05-05 13:14:24 +0800`
+  - 当前分支 `feat/cqrs-optimization a8c6c11e`，committer date `2026-05-05 13:14:24 +0800`
+- 启动时 branch diff vs `origin/main` 为 `0` files / `0` lines，因此继续选择低风险测试回归切片
+- 本轮复核 `CreateGeneratedRegistrySourceShape` 与 invoker emission 路径后确认：
+  - 现有测试已覆盖 request / stream provider 的单一 direct 场景、单一 reflected-implementation 场景、precise reflected 跳过边界，以及各项 runtime contract 缺失分支
+  - 尚未锁定“同一 registry 同时包含 direct registration 与 reflected-implementation registration”时的 descriptor 顺序与 `Invoke*HandlerN` 编号稳定性
+- 已补齐：
+  - `Emits_Request_Invoker_Provider_Metadata_In_Stable_Order_For_Mixed_Direct_And_Reflected_Implementations`
+  - `Emits_Stream_Invoker_Provider_Metadata_In_Stable_Order_For_Mixed_Direct_And_Reflected_Implementations`
+  - 两组 source fixture：`MixedRequestInvokerProviderSource`、`MixedStreamInvokerProviderSource`
+- 通过新增回归，显式锁定以下约束：
+  - provider descriptor 条目按稳定实现排序输出
+  - `InvokeRequestHandler0/1` 与 `InvokeStreamHandler0/1` 的方法编号随 emission 顺序连续增长
+  - 隐藏实现类型不会破坏 direct registration 与 reflected-implementation registration 的混合发射
+

+
+### 当前下一步（RP-083）
+

+2. 若继续推进代码切片，优先复核 invoker provider 之外的 runtime contract 或 fallback selection 分支
+
+### 阶段：benchmark 基础设施引入（CQRS-REWRITE-RP-084）
+
+- 用户明确将当前长期分支目标上提为：系统性吸收 `ai-libs/Mediator` 的实现思路与设计哲学，并将可取部分纳入 `GFramework.Cqrs`
+- 本轮据此调整批次目标，不再把关注点收缩到单个 generator 回归，而是建立能持续比较和吸收设计差异的 benchmark 基础设施
+- 参考 `ai-libs/Mediator` 的 benchmark 设计后，本轮采纳的核心结构包括：
+  - 独立 benchmark 项目壳，而非扩展现有 NUnit 测试项目
+  - 共享 `Fixture` 输出并校验场景配置
+  - `Request` / `Notification` 两个 messaging 场景作为首批最小落点
+  - 自定义列 `CustomColumn`，为后续矩阵扩展保留可读结果标签
+- 本轮新增：
+  - `GFramework.Cqrs.Benchmarks/GFramework.Cqrs.Benchmarks.csproj`
+  - `GFramework.Cqrs.Benchmarks/Program.cs`
+  - `GFramework.Cqrs.Benchmarks/CustomColumn.cs`
+  - `GFramework.Cqrs.Benchmarks/Messaging/Fixture.cs`
+  - `GFramework.Cqrs.Benchmarks/Messaging/BenchmarkContext.cs`
+  - `GFramework.Cqrs.Benchmarks/Messaging/RequestBenchmarks.cs`
+  - `GFramework.Cqrs.Benchmarks/Messaging/NotificationBenchmarks.cs`
+  - `GFramework.Cqrs.Benchmarks/README.md`
+- 设计取舍：
+  - 使用最小 `ICqrsContext` marker，避免把完整 `ArchitectureContext` 初始化成本混入 steady-state dispatch
+  - 直接复用 `GFramework.Cqrs.CqrsRuntimeFactory` 与 `MicrosoftDiContainer`，让基准聚焦于 runtime dispatch / publish
+  - 外部对照组先接入 `MediatR`，保持与 `Mediator` benchmark 的对照哲学一致；但本轮仍只做最小 request / notification 场景
+  - 暂不把 source generator benchmark、cold-start 独立工程或完整 pipeline / stream 矩阵一起引入，避免首批 scope 失控
+- 兼容性修正：
+  - 在根 `GFramework.csproj` 中显式排除 `GFramework.Cqrs.Benchmarks/**`，避免 meta-package 意外编译 benchmark 源码
+  - 将 benchmark 项目加入 `GFramework.sln`，保持仓库级工作流完整
+
+### 验证（RP-084）

+
+- primary metric：branch diff files vs `origin/main`
+- 当前说明：本轮仍在 `50` 文件阈值以内，可继续按 benchmark 场景或 CQRS runtime 对照能力分批推进
+
+### 当前下一步（RP-084）
+
+1. 继续扩展 `GFramework.Cqrs.Benchmarks`，优先补齐 pipeline、stream、cold-start 与 generated invoker provider 对照场景
+2. 当后续有具体 runtime 优化切片时，用该 benchmark 项目验证是否真正吸收到了 `Mediator` 的低开销 dispatch 设计收益
+
+### 阶段：stream request benchmark 对照（CQRS-REWRITE-RP-085）
+
+- 继续沿用 `$gframework-batch-boot 50`，当前 branch diff 相对 `origin/main` 仍明显低于阈值
+- 在 `RP-084` 已建立独立 benchmark 项目后，本轮优先补齐 `ai-libs/Mediator/benchmarks/Mediator.Benchmarks/Messaging/StreamingBenchmarks.cs` 对应的最小 stream 场景
+- 选择 stream 作为第二批 benchmark 的原因：
+  - 已有独立的 `CreateStream` runtime 路径和单独的 stream invoker provider 元数据契约
+  - 与 `Mediator` 的 messaging benchmark 分层直接对应
+  - 不需要像 pipeline / cold-start 那样先进一步澄清运行时或宿主边界
+- 本轮新增：
+  - `GFramework.Cqrs.Benchmarks/Messaging/StreamingBenchmarks.cs`
+  - `GFramework.Cqrs.Benchmarks/README.md` 中的 stream 场景说明
+- 设计约束：
+  - 保持与前一批一致的三路对照：`Baseline`、`GFramework.Cqrs`、`MediatR`
+  - 基准测量“完整枚举 3 个元素”的全量消费成本，而不是只测创建异步枚举器
+  - 使用最小 `ICqrsContext` marker，继续避免把完整 `ArchitectureContext` 初始化成本混入 steady-state stream dispatch
+- 结论：
+  - 当前 benchmark 项目已经覆盖 `Request`、`Notification`、`StreamRequest` 三个核心 messaging steady-state 场景
+  - 下一批更适合转向 request pipeline 数量矩阵或 cold-start / initialization，而不是继续扩同层次的 messaging 基线
+

+

+
+1. 继续扩展 `GFramework.Cqrs.Benchmarks`，优先补齐 request pipeline 数量矩阵，随后再评估 cold-start / initialization
+2. 当需要验证 generated invoker provider 的实际收益时，把 request benchmark 扩展为 reflection / generated provider 对照，而不是只停留在框架间对比
+
+### 阶段：request pipeline 数量矩阵（CQRS-REWRITE-RP-086）
+
+- 继续沿用 `$gframework-batch-boot 50`，当前 branch diff 相对 `origin/main` 仍明显低于阈值
+- 本轮把 benchmark 关注点从单纯 messaging steady-state 扩展到 request pipeline 编排行为，原因是：
+  - `ai-libs/Mediator` 的对照价值已经不只在 request / notification / stream 三个入口本身，还在 pipeline 包装策略与生命周期取舍
+  - `GFramework.Cqrs.Internal.CqrsDispatcher` 已按 `behaviorCount` 缓存 `RequestPipelineExecutor<TResponse>` 形状，因此单独量化 `0 / 1 / 4` 个行为的 steady-state 开销有直接信息密度
+- 本轮新增：
+  - `GFramework.Cqrs.Benchmarks/Messaging/RequestPipelineBenchmarks.cs`
+  - `GFramework.Cqrs.Benchmarks/README.md` 中的 request pipeline 场景说明
+- 设计取舍：
+  - 采用 `0 / 1 / 4` 个 pipeline 行为，而不是立即扩到更大的参数空间，先锁定最有代表性的无行为 / 少量行为 / 常见多行为矩阵
+  - 使用最小 no-op 行为族，不引入日志、计时或上下文刷新逻辑，避免把测量结果污染成业务行为成本
+  - `GFramework.Cqrs` 与 `MediatR` 侧都只注册当前 benchmark 请求对应的闭合行为类型，确保矩阵反映编排成本而非程序集扫描差异
+- 接受的只读 subagent 结论：
+  - 下一批 benchmark 继续优先考虑 `cold-start / initialization` 与 `generated provider` 对照，而不是立即照搬 `Mediator` 的 large-project 维度
+  - 当前 `GFramework.Cqrs.Benchmarks` 仍未接入 `Mediator` 包和 `GFramework.Cqrs.SourceGenerators`，因此本轮不扩成 `Mediator_IMediator` / generated-provider 对照，避免 scope 失控
+- 结论：
+  - 当前 benchmark 项目已经覆盖 `Request`、`Notification`、`StreamRequest` 与 `RequestPipeline`
+  - 后续若要继续贴近 `Mediator` 的 comparison benchmark，最值得优先补的是 initialization / first-hit 与 generated invoker provider，而不是继续横向堆更多 steady-state messaging 入口
+

+

+
+1. 提交本轮 request pipeline benchmark 后，继续扩展 `GFramework.Cqrs.Benchmarks`，优先补齐 initialization / cold-start 场景
+2. 当需要验证 dispatcher 预热与 source generator 收益时，引入 generated invoker provider 对照，并评估是否同时接入 `Mediator` concrete runtime 作为更贴近设计哲学的外部参照
+
+### 阶段：request startup 基线（CQRS-REWRITE-RP-087）
+
+- 继续沿用 `$gframework-batch-boot 50`，当前 branch diff 相对 `origin/main` 仍明显低于阈值
+- 本轮目标：把 benchmark 从 steady-state dispatch 再向前推进一层，补齐与 `ai-libs/Mediator/benchmarks/Mediator.Benchmarks/Messaging/Comparison/*` 更接近的 startup 维度
+- 本轮新增：
+  - `GFramework.Cqrs.Benchmarks/Messaging/RequestStartupBenchmarks.cs`
+  - `GFramework.Cqrs.Benchmarks/README.md` 中的 startup 场景说明
+- 设计取舍：
+  - `Initialization` 只测“从已配置宿主解析/创建 runtime 句柄”的成本，不把完整架构初始化混入 benchmark
+  - `ColdStart` 只测新宿主上的首次 request send；`GFramework.Cqrs` 侧在每次 benchmark 前通过反射清空 dispatcher 静态缓存，避免把热缓存误当 first-hit
+  - `ColdStart_MediatR` 改为真正 `await` 完任务后再释放 `ServiceProvider`，以满足 `Meziantou.Analyzer` 对资源生命周期的要求，并避免 benchmark 本身含有错误宿主释放语义
+- 结论：
+  - 当前 benchmark 项目已经覆盖 `Request`、`Notification`、`StreamRequest`、`RequestPipeline`、`RequestStartup`
+  - 后续若继续贴近 `Mediator` comparison benchmark，下一批最有价值的是 generated invoker provider、registration / service lifetime 与 concrete runtime 外部对照，而不是继续只加同层 steady-state case

+
+### 阶段：request invoker reflection / generated 对照（CQRS-REWRITE-RP-088）
+
+- 继续沿用 `$gframework-batch-boot 50`，当前 branch diff 相对 `origin/main` 仍明显低于阈值
+- 本轮目标：不再只比较 `GFramework.Cqrs` 与 `MediatR` 的外层框架差异，而是开始直接量化 `GFramework.Cqrs` 内部 reflection request binding 与 generated invoker provider 路径的 steady-state 差异
+- 本轮新增：
+  - `GFramework.Cqrs.Benchmarks/Messaging/RequestInvokerBenchmarks.cs`
+  - `GFramework.Cqrs.Benchmarks/Messaging/GeneratedRequestInvokerBenchmarkRegistry.cs`
+  - `GFramework.Cqrs.Benchmarks/README.md` 中的 generated invoker 场景说明
+- 设计取舍：
+  - 采用 benchmark 内手写的 generated registry/provider“等价物”，而不是当轮就把真实 `GFramework.Cqrs.SourceGenerators` 接到 benchmark 项目中，目的是先走通真实的 registrar -> descriptor 预热 -> dispatcher generated path，同时把写入面控制在低风险范围
+  - generated 对照使用程序集级 `CqrsHandlerRegistryAttribute` + `ICqrsRequestInvokerProvider` + `IEnumeratesCqrsRequestInvokerDescriptors`，确保运行时语义与生产路径一致
+  - 在 benchmark 生命周期前后清理 dispatcher 静态缓存，避免 generated descriptor 预热状态跨场景泄漏，污染 reflection 对照
+- 结论：
+  - 当前 benchmark 项目已经能区分 `GFramework.Cqrs` 的 reflection request 路径、generated request 路径与 `MediatR` 外部对照
+  - 后续若继续贴近 `Mediator` comparison benchmark，下一批更适合扩到 registration / service lifetime、stream generated provider，或再决定是否接入 `Mediator` concrete runtime

+- 使用 `$gframework-batch-boot 30` 继续 `feat/cqrs-optimization` 的 CQRS 收口批次
+- 本轮基线选择：
+  - `origin/main c01abac0`，committer date `2026-05-06 09:40:08 +0800`
+  - `main a8c6c11e`，committer date `2026-05-05 13:14:24 +0800`
+- 启动时 branch diff vs `origin/main` 为 `18` files / `2100` lines，低于 `30` 文件阈值，因此继续选择单模块、低风险 benchmark 切片
+- 复核 `GFramework.Cqrs.Benchmarks` 与 `ai-libs/Mediator/benchmarks` 后确认：
+  - `RP-088` 已把 generated descriptor 预热收益量化到 request dispatch 路径
+  - stream benchmark 仍停留在 direct handler / reflection runtime / `MediatR` 三路对照，尚未量化 generated stream invoker provider 的收益
+  - 虽然 `Mediator` 参考基准大量使用 service lifetime 矩阵，但当前 `GFramework.Cqrs.Benchmarks` 尚未建立对称的 scoped host 模式；直接扩 lifetime 会引入超出本批风险预算的宿主语义变化
+- 本轮因此优先选择 request 对称切片，而不是 service lifetime 扩展：
+  - 新增 `Messaging/StreamInvokerBenchmarks.cs`
+  - 新增 `Messaging/GeneratedStreamInvokerBenchmarkRegistry.cs`
+  - 更新 `GFramework.Cqrs.Benchmarks/README.md`
+- 设计约束：
+  - 继续沿用 handwritten generated registry/provider 模式，避免把 benchmark 基础设施与真实 source-generator 输出耦合
+  - 复用与 `RP-088` 相同的 dispatcher 缓存清理策略，确保 reflection / generated 路径对照不受静态缓存残留污染
+  - 使用统一的异步枚举体工厂，让三组 stream handler 共享同一枚举成本基线，把变量收敛到 invoker/provider 接线路径
+
+### 当前下一步（RP-089）
+
+1. 完成本轮 benchmark 项目 Release build、license header 检查与 diff 校验后，更新 active tracking 的权威验证列表
+2. 若 branch diff 仍明显低于 `30` 文件阈值，可继续评估 notification publish strategy 或更贴近 `Mediator` concrete runtime 的单批对照
+3. 若要继续贴近 `Mediator` 的 comparison benchmark 设计哲学，评估是否把 `Mediator` concrete runtime 本身接入 benchmark 项目，而不是长期只保留 `MediatR`
+
+### 验证（RP-089）

+
+### 阶段：手动 benchmark workflow（CQRS-REWRITE-RP-089）
+
+- 新增 `.github/workflows/benchmark.yml`，提供仅 `workflow_dispatch` 触发的 benchmark 入口
+- workflow 默认只执行 `GFramework.Cqrs.Benchmarks` 的 Release build，避免在当前已知 `RequestStartupBenchmarks` 残留未清时默认运行失败
+- 只有在手动输入 `benchmark_filter` 时才执行 BenchmarkDotNet，并上传 `BenchmarkDotNet.Artifacts` 供后续比较
