## What changed - Track the 50 most recently invoked skills for each thread and evaluate them as the `lru_v1` shadow-selection method. - Filter stale and duplicate entries while preserving recency order. - Increase the shadow result limit to 50 and add a `21_50` rank bucket. ## Testing - Add unit coverage for recency refresh, eviction, filtering, limits, and rank buckets. - Add an extension test showing that `lru_v1` recovers a skill invoked on an earlier turn.
