Question on applying Dirty to custom binary files

[izefoea]

I am trying to figure out how to apply Dirty to my own binary files, rather than the provided DIRE dataset. I have attempted to build my own binary file into a new test.jar and modify the "test_file" path in multitask.xfmr.jsonnet, but I am struggling to understand the meaning of the content in the .jsonl files within the provided test.jar (e.g., some key names are t, n, u, etc.). I've checked the relevant information in the paper and it seems that I did not find the answer. I'm not sure if I am on the right track or if I am missing something crucial. Any help on this matter would be greatly appreciated.
