# next/tests/bootstrap_build.sh — Step 4d acceptance test.
#
# Exercises bootstrap:build_genesis/1, verify_genesis/2,
# cidhash_path/1, write_cidhash/2, read_cidhash/1. The bundle CID
# is computed by delegating to the host cid:to_string BIF (Step 1b
# substrate) over the read_genesis result. 11 cases.
