Schema

Column	Type	Description
fact	string	Verbatim declaration with the leading keyword removed: signature and body/proof joined
statement	string	Signature with the leading keyword removed (verbatim slice)
proof	string	theorem/tactic: the { .. } tactic block; definition: the =def= .. body; empty otherwise
type	string	theorem, operator, definition, notation, or tactic
symbolic_name	string	Declaration identifier
library	string	Sub-library
filename	string	Repository-relative source path
imports	list[string]	Unused; always empty
deps	list[string]	Intra-corpus identifiers referenced
docstring	string	Unused; always null
line_start	int	First source line
line_end	int	Last source line
has_proof	bool	Whether a proof block was captured
source_url	string	Upstream repository
commit	string	Upstream commit extracted

Example

bottom-diverges : [ ¬ bot ⇓ ] {
  unfold <not implies>;
  intro; aux {auto; unfold <has-value>; auto};
  bot-div #1
}.

• type: theorem | symbolic_name: bottom-diverges | example/approx.jonprl:13

Use

Statement and proof are available both joined (fact) and split (statement, proof) for proof-term modeling, autoformalization, retrieval, and dependency analysis via deps.
