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":"0d3d0c27-fe4e-438d-b2c7-5234444a8809","date":"2024-05-31","amount":170000.0,"department":"Unknown"},{"id":"cdc71f69-73d1-40b9-9774-8fcdfb4a2647","date":"2024-06-13","amount":100000.0,"department":"Unknown"}],"window_days":90,"content_hash":"39913101007ee577d436b19f317ca376168ce0f42b271317cf1583128d8b8ecd","combined_total":270000.0,"contract_count":2},"published":true,"created_at":"2026-05-27T12:10:41.594799Z","related_entity_type":null,"related_entity_id":null,"reviewed_by":null,"reviewed_at":null,"reviewer_notes":null,"source_document_ids":null}
