Research direction

Start by reproducing the failure on WSL 2 with Ubuntu 24.04.3 after a reboot, using networkingMode Mirrored, and inspect the diagnostic logs around the fallback to networkingMode None. Done means startup consistently retains mirrored networking and the distribution has network access.
