| sourcing event | Connects category strategy, supplier responses, scoring, negotiation state, award recommendation, and reviewer ownership for governed source-to-contract review. |
| contract | Provides price, term, supplier, item, service, plant, renewal, threshold, and exception context used to distinguish leakage from approved buying behavior. |
