Research direction
The issue does not name a file, test, or entry point. Start by locating the repository example that measures a pure computation and reproduce the reported 0ms result; compare the compiled behavior with the source execution order. Done should include a clearly defined correction or explanation, but the issue does not specify which is expected.
