//! Fail-closed weight-buffer parser (`ml_scorer/ml_weights.rs::parse_weights`),
//! reached via the `keyhog_scanner::testing` facade. Migrated from an inline
//! `#[cfg(test)]` block to satisfy the `ml_weights_no_inline_tests` gate (and
//! `ml_weights_no_unwrap_expect`: the unwrap/expect hits were test-body only).
