Situation Monitoring for Active Databases

Summary: Introduces DeltaRelations and incremental relational operators for efficiently evaluating event/condition portions of active-database rules. A chain rule extends incremental evaluation to arbitrary derived expressions, unifying database and nondatabase situation monitoring. (summarized by gpt-5.6-luna on Jul 24 2026)
