Research direction
Start by reproducing the report with `sudo apt install cpuid` and `cpuid | grep ACPI` under WSL 2, then review the attached WSL diagnostic logs and compare the reported feature with the host CPU. Done means WSL reports `ACPI: thermal monitor and clock ctrl = true` when the host CPU supports it, with the relevant behavior covered by validation.
