How to obtain accurate attribution of action fields in the tree

[HerringLiu2333]

Hello!
I want to know, for an insert or move action, how can I know if their parent field corresponds to the content of the source tree or the destination tree? In fact, after collecting some examples, I found that even if they all belong to insert, the parent field of different actions may correspond to different trees, which confuses my work. Is there a way to accurately determine which tree it belongs to? I use gumtree with tree-sitter backend and the actions obtained from parsing two files are roughly as follows:

    {
      "action": "insert-node",
      "tree": "if_statement [5047,5096]", # This belongs to the source tree
      "parent": "compound_statement [4384,5063]",
      "at": 5
    },
    {
      "action": "insert-node",
      "tree": "if: if [5047,5049]", 
      "parent": "if_statement [5047,5096]",
      "at": 0
    },
    {
      "action": "insert-tree",
      "tree": "parenthesized_expression [5050,5073]", 
      "parent": "if_statement [5047,5096]", # This belongs to the destination tree
      "at": 1
    }
