OpenCode-style TUI, model probing, sandboxed auto approval
- TUI: centered home screen with logo, boxed input with mode line, sidebar
(>=120 cols), Ctrl+P palette, Tab Build/Plan, Shift+Tab approval cycle,
mouse (cards, cursor, pickers, wheel), /sidebar /mouse /approval
- /models probing: key check on entry (401 re-asks), API models in /model
- Shell sandbox in C: Linux Landlock (writes limited to workspace/tmp,
ABI>=4 blocks TCP), macOS sandbox_init, rules fallback elsewhere
- Approval modes ask/auto/yolo (default auto); read-only command whitelist;
ask to rerun outside the sandbox when a command looks blocked
- Upgradable bootstrap scripts (git pull --ff-only, rebuild, reinstall) and
cst-agent-update; cst-agent --version
- tests: test_sandbox, test_models
