+  description: |
+    Removes the `pallet-state-trie-migration` from Westend Asset Hub runtime.
+
+    The V0 to V1 state trie format migration has completed successfully on Westend Asset Hub,
+    with 2,082,626 top keys and 28,095 child keys migrated. The pallet is no longer needed
+    and its storage will be cleaned up via RemovePallet migration.
+
+    This change:
+    - Removes pallet-state-trie-migration dependency from Cargo.toml
+    - Removes the pallet's Config implementation and parameter_types
+    - Removes the pallet from construct_runtime! macro
+    - Adds RemovePallet migration to clean up orphaned storage
