The cubefs-mount --socket path was never actually built: CubeFs<B> is generic, so the --socket (DaemonBackend) and default (HashBackend) arms of the match were incompatible types (E0308), and --features mount failed to compile. The running binary was therefore the in-memory build, so --socket was silently ignored and every FUSE write went to RAM and never reached the daemon (rawget/rawkeys returned none / 0 keys, WAL stayed 0). Fix: type-erase the backend. Add (forwards to inner) in cubestore, and build in cubefs-mount via Box::new(DaemonBackend::new(p)) / Box::new(HashBackend::new()). Keeps cubefs free of a cubesys dep (acyclic graph). Verified end-to-end on host (shared code path as the VM): a FUSE write via lands in the daemon store (rawget returns the record, 5 keys present, WAL grows), and survives a of the daemon + relaunch with the same --store (byte-identical read-back). Also includes (from RESUME-cubefs-daemon.md): cubesys raw* command family (rawget/rawput/rawdel/rawkeys/rawscan + parse/hex helpers) and the DaemonBackend client + smoke tests. Report/verification docs added. Note: VM cubefs.service still mounts in-memory (no --socket); update the unit to as a follow-up so the deployed VM FUSE is durable too.
