Research direction
No file, test, or entry point is named. Start by tracing how OpenSBI and the supervisor-mode OS handle mhartid, then compare the requested shartid-like function with the stated read-only requirement; done means establishing and documenting a supported way to obtain the hart ID, or clearly narrowing the request if that is not possible.
