Review Comment:
   The level-check comment above this block still refers to the removed 
RocksDB#deleteFile behavior, but the implementation now deletes via 
deleteFilesInRanges (ManagedRocksDB.deleteSstFileRange). Please update the 
comment to describe the current rationale; otherwise it’s misleading for future 
maintenance.
