# Replace ALL rows of a single variant in a master results CSV with the rows
# from a re-run batch. Useful after running rerun_a1_full_all_datasets.sh:
#
# bash scripts/replace_variant_in_results.sh \
# outputs/cta_test_result/batch_20260602_215923/results_merged_<TS>.csv \
# outputs/cta_test_result/batch_<NEW_TS>/results.csv \
# --variant A1_full
#
# Behavior:
# 1. Verifies both CSVs share the same header.
# 2. Drops ALL rows where column `variant` matches --variant from the master.
# 3. Appends ALL rows where column `variant` matches --variant from the new
# batch.
# 4. Writes a fresh merged file (default: <master>_replaced_<TS>.csv).
#
# The master and new-batch CSVs are NOT modified.
