Field notes
The index distinguishes statement revisions from proof-only revisions, clarifications, unresolved results, and results borrowed from cited work. Its filters sort by recency or revision count and isolate papers with revisions, no required revisions, or cited-result dependencies. A recent entry also displays a 2.5B-token count, but the supplied page text does not explain what it measures.
