Beside the named verbs, `command` takes a command line as the controller's
own shell would — `node account g14 jochen`, `node show ace`, `module list` —
splits it as a shell does (quotes group, backslash escapes, nothing expanded)
and runs it in this binary like every other verb. The named verbs keep their
schemas; this is the whole binary, added because the operator decided any
node may call any tool (hq ADR 0175) and a verb per command was the only
thing keeping the rest behind a shell on the control node. ADR 0154 carries
the dated note. Tests: a plain line, quoted words, an empty line and an
unclosed quote refused.
node-service-manager joins the mesh's own seats, node-scoped, serving eight
verbs — units, status, start, stop, restart, enable, disable, journal — each
with a schema that takes an optional scope, "system" or the operator
account's "user" manager. Sixteen seats now; the count test says so and names
the record.
${machine:account} resolves in a resource's `name` and `user` as it already
did in path, owner and content: the shell module makes the operator's account
its holder's login shell through the `user` shape, and the desktop's watchers
run as that account through a user-scoped unit (host change alongside).
Neither can name the person. A machine with no account refuses by name.
