 ## Use
 
-Statement and proof are available both joined (`fact`) and split (`statement`, `proof`) for
-proof-term modeling, autoformalization, retrieval, and dependency analysis via `deps`.
+Each declaration is split into a `statement` (signature/claim) and a `proof` (body) that are disjoint
+and together form the complete declaration, for proof modeling, autoformalization, retrieval, and
+dependency analysis via `deps`.
