# The definition-of-done gates, in the order the workflow steering requires:
#
#   1. dune build @check   type-checks the libraries and the tests
#   2. dune runtest        runs every Alcotest suite
#   3. dune build @fmt     confirms ocamlformat and dune formatting are applied
#
# Exit status is non-zero if any gate fails, so a cron job or the deployment
# host's trusted receive-hook helper can enforce the same bar with one call. The
# build directory is isolated so a developer's watch build is never disturbed.
#
# Usage: scripts/ci.sh          run all gates
#        BUILD_DIR=... scripts/ci.sh   override the build directory
