	# The platform jobs measure the performance series that the regression gate
	# and the history compare. Each runs on the one runner of its backend's pool
	# that carries `benchmark` instead of `general`, so that no other job can
	# delay it and every workflow run measures its series on the same VM: the
	# pools mix CPU generations and VMs whose results differ by more than the
	# run-to-run noise (#383, #415). A pull request or merge group runs them
	# only when one of their inputs changed, but a dev push, which records the
	# history, runs them for every change but documentation. They wait only for
	# the kernel and the Alpine initramfs, which they boot, and their OpenVMM
	# producer: the package jobs package the release
	# (doc/ci.md#job-graph-and-runner-capacity).
