AI Summary: Debug an issue in the Energy Exascale Earth System Model (E3SM) where output files are incomplete when the restart period is shorter than the `file_max_storage_type` setting. The problem involves investigating why daily average and instantaneous output data are not being written correctly to NetCDF history files, potentially due to overwriting instead of appending. The solution requires analyzing the E3SM code, specifically the I/O routines, and potentially modifying the configuration or code to ensure correct data appending across restart runs.

Complexity: 4/5
