Handler checked for 'null_literal' named child but 'null' is an anonymous node in the Kotlin grammar 3. extractKotlinParameter only searched for 'user_type' direct child, missing 'nullable_type' wrapper (so x: User? never got a base binding) 17 fixtures, 23 describe blocks, 705 new lines of test code, 0 failures. --- AGENTS.md | 2 +- CLAUDE.md | 2 +-
