Expand description

The vocabulary of safety predicates a contract can assert.

Each kind’s meaning, accepted argument shapes, and assembly strategy are declared in spec::SPECS (the single source of truth); this enum only names the kinds. A few kinds carry extra semantics: Null is the guard branch of any(Null(p), …) (proved when p is null), and Owning asserts ownership(*p) = none (psp IV.1 in primitive-sp.md). The kinds Unwrap, Pinned, Opened and Unreachable are declared but not yet verified (the checker returns Unknown), and NonVolatile is assumed satisfied (the VM does not model volatile access).
