+//! Java [`super::super::FrameworkAdapter`] matching LDAP filter-injection
+//! sink constructions.
+//!
+//! Phase 06 (Track J.4).  Fires when the function body invokes one of
+//! the canonical Java directory-client entry points
+//! (`LdapTemplate.search`, `LdapTemplate.find`, `DirContext.search`,
+//! `InitialDirContext.search`, `LdapContext.search`) and the
+//! surrounding source pulls in one of the matching package symbols —
+//! `org.springframework.ldap.*`, `javax.naming.directory.*`,
+//! `com.unboundid.ldap.*`.
