# Runs ON a RunPod pod. Builds the CLEAN (low-order-faithful) clone corpus with a causal
# factored-attention generator and exact ancestral sampling, then self-terminates.
#
# bash cp_causal_bootstrap.sh train <order> <steps>
# bash cp_causal_bootstrap.sh sample <order> <shard> <n_shards> <n_seqs>
#
# Two modes on purpose: the generator is trained ONCE and its weights uploaded, then many pods
# sample from that single generator. If every pod trained its own, the corpus would be a mixture
# of slightly different distributions -- small, but exactly the kind of contamination this whole
# exercise exists to remove.
