//! Review-gated auto-learning report for tool-routing observations (issue #712).
//!
//! The report is derived through the production associative-memory adapter. It
//! ranks persisted observations and amendments by actual usage, mutation, and
//! link degree, while preserving their evidence links. The output is a proposal
//! for human review: it never mutates the seed lexicon automatically.
