Within each filter type, Global รขโ€ โ€™ Controller รขโ€ โ€™ Action scope order applies. IOrderedFilter controls ordering within same scope.

Execution order: Authorization ? Resource ? Action ? Exception ? Result. Filters wrap different pipeline stages and are used for cross-cutting concerns like logging, auth, and caching.
