e621 Image Rater

Pairwise image quality voting for e621 images. Pairs are sampled from prebuilt group buckets.

How it works

• The app loads pool.parquet at startup (from local data/pool.parquet in debug mode, or from the dataset repo in HF mode).
• Each round samples two items from the same group, then shows their image URLs and links to e621 post pages.
• Votes are buffered in memory, then flushed in batches to append-only parquet shards under ratings_log/.
• Local/debug mode defaults: flush every 3 votes or every 15 seconds.
• HF mode defaults: flush every 50 votes or every 300 seconds.

Vote Log Schema

Each vote row stores:

• vote_id
• timestamp (ISO-8601 UTC)
• md5a
• md5b
• winner_md5 (or None for tie)
• url_a and url_b (e621 post URLs)
• dataset
• group
• session_id
