### Describe the bug, including details regarding any error messages, version, and platform. Hello, It's seems that the json generated for the run_end_encoded layout is wrong. If you check the file, you can see that the number of logical value are different, but the number of runs is the same, in the columns of the record batch (except the first one which has empty columns). [run_end_encoded.json](https://github.com/user-attachments/files/21120582/run_end_encoded.json) Tell me if I'm wrong but the number of logical values should be the same in all columns of a record batch ?
