"""Score an emailed submission and push it to the public leaderboard.

Run this on the maintainer's local machine (not on the Space). It needs:
  - `hf auth login` already done, with a user token that has write access on
    Ted412/EgoMemReason-Leaderboard (as repo owner or with a fine-grained
    write scope).
  - a local copy of the private answer key (annotations_private.json). Get
    it once with:
        hf download Ted412/EgoMemReason-Private annotations_private.json \\
            --repo-type=dataset --local-dir /path/to/somewhere

Usage:
    python scripts/publish_submission.py \\
        --submission /path/to/user_submission.json \\
        --private   /path/to/annotations_private.json \\
        --team-name "MyLab" --method-name "MyModel-8B" \\
        --model-size "8B" --uses-external no --uses-frames frames-only \\
        --method-description "Frame sampling + LoRA on top of Qwen2-VL-8B." \\
        --project-url https://... --publication-url https://arxiv.org/abs/...
