# CRITICAL PATH CONSTRAINT
# ------------------------
# NICHART_DATA_ROOT, NICHART_SIF_DIR, and NICHART_SLURM_LOGS_DIR must use
# the same absolute paths on the API server host AND the SLURM compute nodes.
# The API server builds apptainer bind-mount paths from these roots and passes
# them verbatim inside the sbatch --wrap command that runs on a compute node.
# If the paths differ, the apptainer job will fail to find its inputs.
#
# Example: if your shared filesystem is mounted at /shared/nichart everywhere,
# set NICHART_DATA_ROOT=/shared/nichart/data on both the login node and in .env.
