## What changed - Add a character n-gram selector that scores matches across skill names, short descriptions, and descriptions using field weights and inverse document frequency. - Include the selector in the shadow selection experiment alongside the existing lexical selectors. - Bound query, document, candidate, and result processing, and report query or candidate truncation through the existing selection metadata. ## Testing Add unit coverage for related word forms, typos, CJK text without word boundaries, and bounded inputs.
