Cubic keeps pushing until packets drop, which stands queues up in the path
on fast links. BBR paces to its estimate of bottleneck bandwidth and minimum
RTT instead, cutting queueing latency while keeping throughput. fq is the
qdisc BBR is built to pace through.
tcp_bbr and sch_fq are modules in every kernel Omarchy ships and autoload
when the sysctls are set. The migration re-applies the shipped file so new
connections switch without a reboot, no-ops once the live values match, and
flags a reboot if applying fails.
