+Template-friendly default: use header or host resolution. Route-based extraction requires routing middleware before the multitenancy middleware.

 If you use MediatR request logging pre-processors (template default), register `AddCleanArchitectureMultitenancyCorrelationPreProcessor` before logging so request logs include tenant context.
 In the Jason Taylor template, keep the multitenancy pipeline after authorization behaviors so authorization runs first.
+The correlation pre-processor registers a matching post-processor to clean up log scopes.
