"""Centralized path-derivation rules for the judge training pipeline.

Every script — Python or bash — that needs to resolve a path from a
prompt-config name should go through this module.  Bash callers can
``eval "$(python -m judge_training.data.naming <prompt_config>)"``
to set the shell variables.
