//! Tests for the RSI built-in-tool ban guard (#236).
//!
//! The RSI escalated `hashline_edit` to a "blanket DO NOT USE" directive over
//! recoverable failures. The guard rejects brain-file content that bans a
//! built-in tool, while still allowing nuanced routing guidance and command
//! rules.
