Jobmon Task Runner
CLI entry point for Jobmon worker tasks. Loads the task’s metadata JSON
and runs the appropriate work horse in-process. Invoked by every
psimulate command that submits simulations (run / restart /
expand / load_test) as well as workflow simulation steps.
Logging is configured via _configure_dual_sink so loguru INFO+
messages land in the SLURM stdout file and WARNING+ messages land in the
SLURM stderr file (which the Jobmon GUI surfaces).
