# Description:
# Check if there are cached state disks available for subsequent jobs to use.
#
# This lookup uses the state version from constants.rs.
# It accepts disks generated by any branch, including draft and unmerged PRs.
#
# If the disk exists, sets the corresponding output to "true":
# - lwd_tip_disk
# - zebra_tip_disk
# - zebra_checkpoint_disk
