"""Check that every counted leaderboard attempt has its run on HF (works without a token).

usage: python3 check_coverage.py [trials.csv] [--revision REV]

For each row of trials.csv (one row per counted attempt), it checks in the dataset MLL-Lab/embodied-exam-runs:
  - runs/<h2>/<slug>/run.json and trajectory.jsonl.gz exist, and replay.mp4 exists when has_video = 1;
  - the slug has a row in index/<suite>.json whose run and outcome equal the leaderboard's.
It lists the runs/<h2>/ folders through the HF API (at most 256 calls) and reads the index files. Without a token,
HF's rate limit may make it wait a few minutes; with HF_TOKEN set it runs in about a minute.
Exit status 0 only at 100% coverage.
