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

BoolWellFoundedOrder
{
    //Booleans
    axiom bool_ax_dec{
        decreasing(false, true)
    }
    axiom bool_ax_bound{
        forall bool1: Bool :: {bounded(bool1)}
            bounded(bool1)
    }
}

• type: domain | symbolic_name: BoolWellFoundedOrder | src/main/resources/import/decreases/bool.vpr

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.
