 ## Module Contract
 
-The module registers the `organizations.directory` capability from
-`govoplan_core.core.organizations`.
+The module registers two capabilities from
+`govoplan_core.core.organizations`:
+
+- `organizations.directory` for backward-compatible direct unit/function
+  lookup;
+- `organizations.hierarchyDirectory` for typed, tenant-safe, explicitly
+  structure-scoped hierarchy and path resolution.
 
 Feature modules should consume the capability instead of importing
 organization ORM models.
