# This workflow here on the master branch attempts a git rebase of the platform
# branches listed in the build matrix below. If the rebase succeeds, the rebased
# branch is pushed under the name `<branch>-rebased`. This triggers the build
# workflow on the `<branch>-rebased` branch, which will run the proofs. If the
# proofs succeed, the `<branch>-rebased` branch is force-pushed over
# `<branch>`, becoming the new platform branch.
