When the combined value crosses a procurement-approval threshold but each individual award stays below it, the pattern is classically called 'contract splitting' and warrants further review against the procurement code and any sole-source justifications. The pattern can also reflect legitimate phased work or multiple unrelated services with the same vendor. Tier 2: vendor-named observation, no individual characterization.","fiscal_year":null,"review_status":"auto","review_tier":2,"evidence":{"vendor":"NAMI Lexington","contracts":[{"id":"147668b9-821b-4962-aeee-2e8bad20c1ce","date":"2023-05-30","amount":170000.0,"department":"Unknown"},{"id":"d05a5334-28f2-4716-91ea-3b8b76081a9d","date":"2023-08-08","amount":55000.0,"department":"Unknown"}],"window_days":90,"content_hash":"612ea59468202be28ad75b3f98d63348aa2b1fd36a8c8b1d18df787160076e69","combined_total":225000.0,"contract_count":2},"published":true,"created_at":"2026-05-27T12:10:41.589300Z","related_entity_type":null,"related_entity_id":null,"reviewed_by":null,"reviewed_at":null,"reviewer_notes":null,"source_document_ids":null}
