# One-off patch of the dataset's v1.2 shards to v1.3 (lead, 2026-11-05): prefill rows with condition "setup" dropped, as
# the steering runs dropped that planted conclusion when its kind joined "It's not real". Same shards, schema and compression;
# rewrites build_report.json counts.
# Usage: python patch_v1_3.py <dataset folder>
