From review: the store and broker passwords genesis makes were carried into
the controller through a world-readable file in /tmp, a bundle left at 0644 by
an earlier installer kept that mode while now holding them, a mesh raised by
the old installer would have been handed new passwords its servers do not have,
and the broker-admin action's marker did not depend on the value. Secrets now
stage in a 0700 directory owned by the controller's account; the bundle is
chmod'd; an existing store or broker volume with no credential file is refused
by name; the marker holds the password's fingerprint. Also: one install path
for the store, broker and vault, no error-string matching for the operator
key, and no unreachable fallback for the superuser.
One name per thing, per the HQ glossary: the module/container/image/binary/repo
becomes mesh-controller, the seat the-controller, and the store+broker pair the
foundation (embedded base bundles, default template and example lock renamed with
their go:embed directives). No behaviour change — a pure vocabulary rename.

Steps 6 to 10, which turn a substrate into a mesh that can maintain itself
(novox/hq ADR 0067).
6 enrol a node record, a token, `mesh-host enrol`, and the host agent
running. Proved by the mesh having HEARD from the node, not by a
process existing: a host that cannot reach the broker looks exactly
like a successful install until the first push applies nothing.
7 registry the module that gives this mesh an image store, registered from a
--catalog checkout, assigned and pushed. Its image is upstream and
never built (04-ISSUES/029) — a placeholder digest there is refused.
Verified by asking `/v2/`, because a container that is up is not a
registry that serves.
8 publish the carried image pushed into that registry, which assigns it the
first manifest digest it has ever had. This is the hinge: without
it the mesh works and can never upgrade itself.
9 control the control plane registered as an ordinary module pinned to that
digest, with the substrate's own store connections delivered
through `secret accept` — read out of the bundle that made them,
because the mesh cannot invent a credential that predates it.
10 retire the temporary control plane dropped from the bundle and removed by
the host's ordinary removal pass.
Every step asks before it acts and reports "already done". No step leaves the
machine without a control plane: steps 9 and 10 overlap deliberately, and two
stateless control planes are untidy rather than broken.
mesh-control's `internal/builder`.PublishImage is mirrored rather than imported —
tier 0 depends on nothing that must be installed first — with one correction: the
digest is chosen from RepoDigests by repository instead of taken as element zero,
so an image pushed to two registries cannot silently pin this mesh to the wrong
one.
