hybrid-search-implementation

The fragment is legitimate hybrid-search implementation code and does not show evidence of malware. It contains a material SQL injection risk through the unvalidated filter_metadata key and a conditional script-injection risk through interpolation of boost_vector into an Elasticsearch Painless script. Validate or parameterize these inputs before production use; also add the missing asyncio import. Overall risk is moderate due to the SQL construction flaw, not due to supply-chain malware indicators.
