Every incus verb is a candidate feature request, and wrapping them one at a
time grows a worse incus. This lands the rule instead: claudebox owns a command
when it must enforce an invariant incus cannot see — the user.claudebox=1
boundary, the isolation stack, or the creds-free snapshot workflow. Everything
else is incus's job, and now has a door.
- CMDS table: one row per command, carrying synopsis, preconditions, summary,
action and success message. Dispatch AND help are rendered from it, so the
help can no longer describe a command that doesn't exist — the drift that
produced #8 is now impossible, not merely fixed.
- rename, via a table row: it needs the box stopped (incus won't rename a
running instance), so it says so instead of leaking an incus error.
- `claudebox incus <box> -- <args...>`: the escape hatch. Box resolved and
tag-checked, rest passed to incus verbatim, {} substituted, command echoed.
Warns when it can move a box off the isolation stack.
- The boundary is now ENFORCED, not assumed: every box-taking command resolves
through the user.claudebox=1 tag, so claudebox will not stop, rename or delete
an instance it didn't mint.
- The rule, written into docs/claudebox-design.md.
