#!/usr/bin/env python3
"""Remove the legacy `Rubric_v1_backup` field from the ABForge HF dataset, and
(optionally) refresh the dataset card.

Usage:
    # 1) make sure the cached HF token is SlowGuess's (write-enabled), e.g.
    #    python -c "from huggingface_hub import login; login()"   # paste token
    #
    # 2) dry run -- only reports which files contain the field (no download of
    #    big files, no changes pushed):
    DRY_RUN=1 /path/to/conda/abforge/bin/python remove_rubric_v1_backup.py
    #
    # 3) apply -- downloads matching files, strips the field, re-uploads, and
    #    updates the card, all in ONE commit:
    DRY_RUN=0 /path/to/conda/abforge/bin/python remove_rubric_v1_backup.py
