- cubesys/src/bin/cube.rs: route known command words (prog/write/run/ls/stat/
seal/open/query/begin/commit/rollback/stats/audit) straight to Session::exec
from argv, making the coordinate-addressed 'open <path> <K.Z.Y.X> <tf>' surface
(Phase 3 'open by CZYX + flags') a real CLI command, not REPL/script-only.
Verified: ./check green; cube open/cube bogus both behave; dispatch reaches
crypto/run layer over in-process and durable daemon (cubec) paths.
- STARTUP-README.md: add verification points per standing directive; mark
Phase 2 FS + durability VERIFIED, Phase 3 surface DONE, boot-substrate IN PROGRESS.
- Guest binaries synced to host HEAD f40b448 + this change; OS state now persists
on the cube store in the VM (/cubefs/c200/...), durable across daemon restart.
Implements the requested cube service: a long-lived daemon that holds ONE
CubeStore for its whole lifetime and serves the cube command language over a
Unix-domain socket, plus cubec to talk to it.
- cubesys::commands: factored the single command interpreter (Session::exec)
so cube REPL, cubec client, and the daemon run identical logic
- cubesys::net: dependency-free length-framed AF_UNIX transport
- cubesys::persist: dependency-free JSON snapshot (atomic tmp+rename) so the
store -- including sealed/encrypted records -- survives daemon restarts
- cube-server: listens on $XDG_RUNTIME_DIR/cube/cube.sock, snapshots to
$XDG_STATE_HOME/cube/cube-store.json, replays on startup
- cubec: one-shot + REPL client over the socket
- cube.rs trimmed to a thin REPL/script/demo driver (help text updated)
- /etc/systemd/system/cube.service: runs as luulu, ProtectSystem=strict,
RestrictAddressFamilies=AF_UNIX, Restart=on-failure; enabled + active
- integration.md documents the daemon + caveat (open rewrites plaintext)
Verified: ./check (fmt+tests+clippy -D warnings) green; ./check mount (27
FUSE e2e) green; socket CLI round-trips; sealed record survived a full
service restart and reopened+r with original value.
Integrates Packages 3-5 over a single shared CubeStore, the literal
CUBELinux premise (data addressed by coordinate, not path). Adds the
cubesys crate (lib + cube CLI + cube-demo) proving two end-to-end
properties: a cubefs path IS a runnable code cell at the same coordinate,
and a sealed record reopens and runs on the same store.
Two latent cross-crate bugs surfaced and fixed while integrating:
- cubecoords: refresh_flags() now preserves out-of-band flag bits
(8..=15), so cubecrypt's HEADER_FLAG_ENCRYPTED survives refresh.
- cubestore: record codec now serializes raw flag bits (TLV tag 12) so
the encrypted bit survives the store round-trip.
All gates green (./check, incl. cubefs --features mount).
