//! CLEANLIB-518 (§2) — null verdict label tolerance parity.
//!
//! Before: a `verdict: null` (or `verdict_label: null`) wire rejected the whole
//! parse in Rust (`invalid type: null, expected a string` — Test 743061), while
//! sdk-py/js/go degraded tolerantly to WARN + VERDICT_NOT_YET_ASSESSED. This
//! brings Rust to parity: a null label parses to the empty label, which the
//! status/reason mapper resolves to the fail-closed default.
