opencrabs 0.3.83

//! The vacuous-pass guard, across the runners a multi-language box actually uses.
//!
//! It read cargo's format alone, so in any repository that is not Rust the
//! protection did not exist: a filter that matched nothing exited 0, parsed as
//! `None`, and the gate stamped it verified.
