- cube-bench crate: real-code-path throughput/latency over cubestore,
cubecrypt (aes/gcm/chacha/xts), cubecode VM, and cubesys Session.
Every section asserts correctness before timing. Wired into ./check
as an opt-in 'bench' stage.
- cubesys Session: per-command latency histogram + per-C-namespace record
counts, exposed via a new 'stats' command over the live socket.
- Deployed rebuilt cube-server to /home/luulu/.cubelinux/bin and
restarted the system cube.service; verified stats live.
