# The quick check on every push: each board's image builds, and the v4 tests pass. A pull
# request into master is gated by acceptance.yml, the full acceptance protocol.
# Nothing is published here. The nightlies own the rest: nightly.yml (the QEMU acceptance boots,
# the 32-bit build, the Isabelle/HOL proofs, the images to Nexus) and nightly-docs.yml (the
# documents to Nexus).
