The loop the whole thing exists for: told, apply, report.
`run` holds one outbound connection open and consumes the node's own queue.
Every declaration is verified against the control plane's signing key before a
byte of it is read as an instruction -- not once at connect, every time. The
transport being pinned is a different question from the instruction being
genuine, and pinning only the first would make the second transitive: a
compromised broker could forge declarations, and this host applies whatever the
link delivers.
Malformed and forged are reported differently, because ADR 0004 requires a host
to tell "this is not from the mesh I joined" from "this is broken". One means
somebody is trying and the other means something needs fixing.
A node now keeps what it needs to come back on its own: the broker's address
and fingerprint, the signing key it believes, and its own broker password --
which the mesh issues at enrolment to replace the token's secret, so the
one-time thing stays one-time and the credential it holds for years is not the
one that was pasted into a terminal.
Verified in the lab end to end. The node enrolled, held its link, received a
signed declaration and applied it -- the file is on the machine with the right
contents, and the host's own record lists both resources.
That run also found issue 010, which is recorded in novox/hq: the declaration
removed every container on the machine, including the control plane that sent
it. Correct reconciliation, shared store, and the first thing that happens.
