Struct ExpertFileWriter 

pub struct ExpertFileWriter { /* private fields */ }

Offline writer: creates the manifest + one file per MoE layer and places records at their strided offsets. Plain buffered writes (no O_DIRECT) — alignment only matters on the streamer’s read path, and the record stride is already a 4 KiB multiple, so the files are O_DIRECT-readable.
