type	string	Declaration keyword
symbolic_name	string	Declaration identifier
library	string	Sub-library
filename	string	Repository-relative source path
imports	list[string]	File-level `Require`/`Import` modules
deps	list[string]	Intra-corpus identifiers referenced
docstring	string	Preceding documentation comment, empty if absent

Example

AVTree {
  values: set Value,
  attributes: set Attribute,
  root: values - Wildcard,
  av: attributes one -> some (values - root),
  va: (values - Wildcard) one -> attributes
}
{
  // values (and attributes) of tree are those reachable from root
  values = root.*(va.av)
}

type: sig | symbolic_name: AVTree | algorithms/discovery/ins.als

Use

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.
