//! Adversarial coverage for the bash hard blocklist (`check_blocked_command`).
//!
//! The deterministic counterpart to the Docker security eval: these run in CI,
//! need no model, and pin that catastrophic commands are blocked — including
//! the bypasses an earlier matcher missed (reversed flags, quoted `$HOME`,
//! long flags, chained `rm`). They also pin that legitimate deletes are NOT
//! blocked, so the gate doesn't get so strict it breaks normal work.
