调研方向

Start with the failing DacDbiComWrappersDumpTests.GetObjectForCCW_ComWrappersIdentityPointer_ReturnsManagedObjectWrapperHandle test on linux_arm and inspect the linked build and repeated failure reports. The issue provides no source file or expected fix; determine why the assertion receives -2146231223 instead of 0. Done means the test passes for the affected configuration and the known issue no longer matches.
