"""Aggregate mute/swap accuracy across all models in /home/ubuntu/eval_results.

For each (model, prompt_mode) we report:
  mute      : detection rate on muted inputs   (positive = muted)
  mute_org  : detection rate on original audio (positive = synced)
  swap      : detection rate on swapped inputs (positive = mismatched)
  swap_org  : detection rate on original audio (positive = synced)
  mute_all  : combined accuracy = (correct_mute + correct_mute_org) / (n_mute + n_mute_org)
  swap_all  : combined accuracy = (correct_swap + correct_swap_org) / (n_swap + n_swap_org)

When sample sizes match, the combined number equals the simple mean of the two rates.
