deepseek-ai/3FS ? reverse-engineered prompt

Build me the Fire Fly File System project so I can run a working test cluster and understand how to use it.

I want a distributed file system that is fast enough for AI training and inference jobs, with normal file and folder access, strong consistency, and support for things like data preparation, dataloading, checkpointing, and KV cache storage. Please make sure the repo builds cleanly, the setup steps work, and the main documentation is enough for someone to get it running without having to guess. If there are any missing dependencies or version gotchas, handle them or call them out clearly. I’d also like a simple way to verify it works, ideally with a small test cluster and one benchmark or smoke test. Look up current docs online if you need to.
