//! Guard that prevents RSI from appending raw failure-event logs to brain
//! files (issue #111). The function under test is private to
//! `brain::tools::self_improve`; we exercise it via the public
//! `self_improve` tool's `apply`/`update` actions, asserting that the
//! known bad-shape headers come back as errors and clean derived rules
//! pass through.
