#!/usr/bin/env bash
# Sweep all 6 perturbations x 5 levels = 30 robustness runs for CTA.
# Mirrors X-AVDT's robustness sweep.
#
# Usage:
#   bash scripts/analysis/run_robustness_sweep.sh \
#       <ckpt> <data_config> [demographics_csv]
#
# Examples:
#   # On the diffusion-only test split (held-out 3 families inside ours):
#   bash scripts/analysis/run_robustness_sweep.sh \
#       outputs/cta_diffusion_combined_20260604_205145/checkpoints/epoch16-valauc1.0000.ckpt \
#       fairtalking_diffusion_only \
#       /apdcephfs_gy4/share_303628665/joywu/research/test.csv
#
#   # Or on the held-out family test sets one by one:
#   bash scripts/analysis/run_robustness_sweep.sh <ckpt> fairtalking_test_sadtalker
#   bash scripts/analysis/run_robustness_sweep.sh <ckpt> fairtalking_test_edtalk
#   bash scripts/analysis/run_robustness_sweep.sh <ckpt> fairtalking_test_float
#
# Output: results appended to outputs/analysis/robustness/cta_runs_<TS>.json
