   - 已完成一轮 invoker provider gate 合同回归：
     - `GFramework.SourceGenerators.Tests/Cqrs/CqrsHandlerRegistryGeneratorTests.cs` 现新增四条回归，分别锁定 request / stream 在缺少 `ICqrsRequestInvokerProvider`、`IEnumeratesCqrsRequestInvokerDescriptors`、`ICqrsStreamInvokerProvider` 或 `IEnumeratesCqrsStreamInvokerDescriptors` 时，generator 都会整体跳过对应 provider 元数据发射
     - 本轮最初采用固定源码片段替换来裁剪测试输入，但因三引号字符串缩进差异导致 helper 过脆；当前已收敛为按稳定起止标记移除源码块的 `RemoveBlock(...)` helper，避免 gate 回归依赖精确空格对齐

+    - `GFramework.Cqrs/Internal/CqrsDispatcher.cs` 现把 `Delegate.CreateDelegate(...)` 抛出的 `ArgumentException` 统一包装为已有 XML 文档承诺的 `InvalidOperationException`，保持 request / stream 两条错误消息语义一致

+### 阶段：generated invoker provider runtime 失败边界修复（CQRS-REWRITE-RP-073）
+
+- 在 `RP-072` 提交后继续按 `gframework-batch-boot 50` 执行；当前 branch diff 相对 `origin/main` 仍为 `24 files`，文件阈值 headroom 依然充足，因此继续推进下一批 runtime 失败边界回归
+- 本轮原计划只补 `CqrsGeneratedRequestInvokerProviderTests` 的 request / stream 非 happy-path 回归，但定向测试首轮直接暴露出一个真实 runtime 缺口：
+  - `CqrsDispatcher.CreateRequestInvokerDescriptor(...)` 与 `CreateStreamInvokerDescriptor(...)` 的 XML 文档和消息语义都承诺会抛 `InvalidOperationException`
+  - 实际实现先调用 `Delegate.CreateDelegate(...)`，当 invoker 签名不兼容时会直接冒出 `ArgumentException`，导致文档承诺与运行时行为不一致
+- 主线程已完成：
+  - `GFramework.Cqrs.Tests/Cqrs/CqrsGeneratedRequestInvokerProviderTests.cs` 新增 request / stream 两组 `non-static invoker` 与 `incompatible invoker` 回归，并保留 request / stream happy-path 作为同批守护断言
+  - `GFramework.Cqrs/Internal/CqrsDispatcher.cs` 现对 request / stream 两条 descriptor 创建路径统一捕获 `ArgumentException`，并转换成带原有错误消息的 `InvalidOperationException`
+  - 新增异步断言已补齐 `ConfigureAwait(false)`，避免测试批次自身引入 `MA0004` analyzer warning
+
+### 验证（RP-073）
+
+- `dotnet build GFramework.Cqrs.Tests/GFramework.Cqrs.Tests.csproj -c Release`
+  - 结果：通过
+  - 备注：并行执行 build/test 时曾出现 `MSB3026` 输出文件竞争噪音；无真实编译失败，也未引入新增 analyzer warning

+  - 结果：通过，`6/6` passed
+
+### 当前下一步（RP-073）
+
+1. 先提交本轮 runtime 失败边界修复与恢复点更新
+2. 重新复算 branch diff 后，再判断是否继续推进剩余 provider 失败边界或在接近阈值前停下
+3. 若继续下一批，优先保持单文件或双文件写集，避免在本轮后段扩散 review 面积

 ### 阶段：invoker provider gate 合同回归（CQRS-REWRITE-RP-072）
 
 - 在 `RP-071` 提交后继续按 `gframework-batch-boot 50` 执行；当前 branch diff 相对 `origin/main` 仍为 `24 files`，未接近主要 stop condition，因此继续追加一轮 test-only generator 合同回归
