2
3What a fleet member keeps on disk (`mfp_persist`): its term, its vote in that term, the last document
4it accepted from a leader and the last it knows committed. `mfp_encode` / `mfp_decode` are the Rust's
5state file text (`systems N`, `term`, `voted`, then each document prefixed by its length); a file
6written for another cluster size is refused. Writing it safely (temp, fsync, rename, directory fsync)
7is `@ajax/mesh-fleet-store`.
