+        When reviewing batched Merkle tree documentation changes:
+        1. **Critical**: Verify that all function signatures, struct definitions, and behavior described in the documentation accurately match the actual implementation in `**/src/`
+        2. Cross-reference any mentioned function names, parameters, return types, and error conditions with the source code
+        3. Check that code examples and usage patterns reflect the current API in the crate
+        4. Validate that any referenced constants, enums, or type definitions exist and have correct values
+        5. Ensure documentation describes the actual behavior, not outdated or planned behavior
+        6. Flag any references to deprecated functions, renamed structs, or changed interfaces
+        7. Verify that error handling and edge cases mentioned in docs match the implementation
+        8. Check that performance characteristics and complexity claims are accurate
+        9. Do you see any inconsistencies between the documentation and the code in either way?
+        10. Do you see any weird patterns or anything that doesn't make sense in code or docs?
