"""Step 4 of 4: score a submission.

    python scripts/04_evaluate.py --selections my_method.jsonl \\
        --track ./track --name my_method

Needs a reader model serving an OpenAI-compatible endpoint. Every published
number used Qwen3.6-27B on local hardware:

    vllm serve Qwen/Qwen3-VL-27B-Instruct \\
        --max-model-len 16384 --gpu-memory-utilization 0.90 \\
        --reasoning-parser qwen3 --no-enable-prefix-caching

Two calls per (frame, chain) pair. Five frames across 204 films with ten chains
each is about 20,000 calls, so try `--movies` with a few films first.

The reader is part of the specification. Frame-level scores from a different
reader are not comparable with the leaderboard, even though the method ranking
survives a reader change.
