## Tools (as reported by the server, not verified)

- `search\_library`: Search 2497 readings taken from 234 arXiv papers' LaTeX source: citation stances \(adopts, extends, disputes, measures against\) and stated assumptions. Matches on the quoted sentence, the cue phrase that decided it, and the work cited. Returns the sentence verbatim with a link to the exact line.
- `read\_paper`: Everything Keystone reads out of one arXiv paper: what it adopts, extends, disputes and measures against, and the assumptions it states with a citation, its own evidence, or nothing at all. Works for any paper on arXiv that ships LaTeX source — one outside the library is parsed on demand, which take
- `list\_disagreements`: Every sentence in the library where a paper says prior work is wrong, or puts itself beside it to win. Small on purpose — disagreement is rare and concentrated, and the whole set is readable.
