- 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.
