ML research datasets from ArXiv and Semantic Scholar (JSONL, quality-scored)

I kept rebuilding the same arXiv scraper at the start of every ML project. After the third time I wrote a dedup pipeline, I automated the whole thing.

The interesting part is that the pipeline is shared; if two people subscribe to the same topic, they share one crawl and one deduplicated record pool. Happy to talk through the pgvector dedup approach if anyone's curious.
