          DGE (does not run DESeq2). Valid pairs feed ``run_differential_expression`` when DE omits
          conditions. **(3)** Pathway steps follow DE.
        - ``run_differential_expression``: PyDESeq2 contrast (needs ``condition_a`` /
          ``condition_b`` when using count-matrix cases).
        - ``run_pathway_enrichment``: ORA on DE genes vs pathway gene sets.
        - ``compare_pathways``: contrast exclusive vs shared DE support between two
          pathways (``pathway_a``, ``pathway_b``).
        - ``submit_answer``: submit ``hypothesis`` pathway name and end episode.
