## What changed - Add a bounded BM25 selector that ranks skills across name, short-description, and description fields, weighting names most heavily and rare terms more highly. - Run the selector alongside the weighted lexical method in the shadow-selection experiment, with deterministic tie-breaking and existing per-method metrics. - Add unit coverage for field weighting, rare-term ranking, unmatched queries, and input limits. - Remove the implicit-invocation integration test and its telemetry development dependency.
