# A release: pushing a tag v<version> builds that commit exactly as the nightly does -- the
# acceptance protocol, the proofs, the board images -- and the documents, and publishes both to
# starshipos-releases at that version:
#
#   org.starship:kernelImage:<version>     classifiers pc, raspi5, milkv, logs (nightly.yml)
#   org.starship:documentation:<version>   classifiers book, vol1, vol2, vol3, api (nightly-docs.yml)
#
# The tag must name the version the tree says it is: v<LITHOS_VERSION> (kernel/Makefile). A tag
# that does not is refused before anything is built. A release repository takes a version once.
