 ## Test Status Summary
-The 14-15 transformer is in active development with 5 tests passing (improved from 2). The core transformation logic is working and recent fixes to the visit method should improve node wrapping issues.
+The 14-15 transformer is in active development with 6 tests passing (improved from 2). The core transformation logic is working and recent fixes to the visit method have shown some improvement, but String transformation issues persist.
 
-## Primary Issue: Node Wrapping Problems (FIXED)
-The main issue was that the `visit` method wasn't properly calling specific node transformation methods like `String`. Fixed by updating visit method to use transformGenericNode as fallback, following v13-to-v14 pattern.
