# Runs the seed builds and the full-API build with assertions after pushes that change
# what they compile, so the ccaches track the branch instead of going stale
# between releases. PR, merge queue and feature branch builds restore these
# caches and never save. Without this workflow every PR pays the accumulated
# submodule delta on every platform.
#
# The branch patterns narrow the trigger to main and the release branches; the
# job conditions then require a protected ref, the same rule the ccache-action
# saves under, because the pattern also matches names like vendoring-v2.0-x.
# Keep this file identical across the branches that have assert_test.yml.
