"""
Sample submission script for Task 23: Property Inference.

Auxiliary dataset: https://huggingface.co/datasets/SprintML/Property_Inference
Download texas_auxiliary.npz from there and place it in the same directory as this script.

Steps:
  1. Query the predict API for each model using auxiliary probe data
  2. Compute a confidence score per model (higher = more likely World A)
  3. Save predictions to submission.csv
  4. Submit submission.csv to the hackathon platform

Submission format (submission.csv):
    model_id,score
    0,0.73
    1,0.41
    ...

Where score is a float in [0, 1]:
    - Higher score = more likely World A (70% male training data)
    - Lower score  = more likely World B (50% male training data)
    - 0.5 = uncertain (this is the default for missing model_ids)
    - Do not submit scores of exactly 0 or 1

All 140 model_ids should be included. Missing ones default to 0.5.

API rate limits:
    - Per model: 15 minute cooldown after a successful query
    - Failed requests: 2 minute cooldown
    - Max batch size: 100 records per request
