+// Query to Create a New Scenario and its Delta (MODIFIES relationship)
+// This allows defining a new 'what-if' scenario by specifying changes to a job's properties.
+
+// Parameters:
+// :new_scenario_id => 'what-if-2'
+// :description => 'Job 5 기간 단축 시나리오'
+// :target_job_id => 5
+// :new_duration_value => 3
+// :new_cost_value => 50
+
+// 1. Create the new Scenario node if it doesn't already exist
+MERGE (s:Scenario {id: $new_scenario_id})
+ON CREATE SET s.description = $description
+
+// 2. Find the target Job to modify
+MATCH (j:Job {id: $target_job_id})
+
+// 3. Create or update the MODIFIES relationship between the Scenario and the Job
+//    This relationship holds the delta (the new property values for this scenario)
+MERGE (s)-[m:MODIFIES]->(j)
+ON CREATE SET m.new_duration = $new_duration_value, m.new_cost = $new_cost_value
+ON MATCH SET m.new_duration = $new_duration_value, m.new_cost = $new_cost_value
+
+// 4. Return the created/updated Scenario and the modified Job for confirmation
+RETURN s, m, j;
