+The bundle listens to **Doctrine** lifecycle events (`postPersist`, `postUpdate`, `preRemove`) to automatically detect

 process them.
 
+By default, the bundle registers a Doctrine DBAL middleware that triggers the processing of collected purge requests
+right after the database transaction is committed. This ensures purges only happen for changes that were actually
+persisted. If the middleware is disabled (`doctrine_middleware: { enabled: false }`), the bundle falls back to
+Doctrine's `postFlush` event instead, which runs after changes are flushed but before an eventual wrapping transaction
+is committed.

 The bundle uses **purge subscriptions**, which are predefined rules that associate specific entities and their
 properties with corresponding routes and route parameters. These subscriptions help identify which content should be
 purged based on changes to the entities.
