swarm-controller's POST /api/agents now refuses (409) a name the swarm
has already placed on a different hive: a non-Destroyed declaration in
that hive's wanted state, or a SetAgentWanted node still queued for it.
The same name on the same hive is that agent being re-created and goes
through. A wanted state that cannot be read refuses (503/500) instead of
reading as "placed nowhere". Creations are serialised from that read to
the graph insert so two concurrent creations of one name cannot both
pass.
Hive-level creation is removed: hivectl `agent create` / `request-create`,
HostRequest::Spawn / RequestSpawn, the dashboard POST /api/request-spawn
route, and ApprovalKind::Spawn with its approve/resolve arms and the
approval-carrying `templates::spawn`. The swarm path (deploy request or
wanted-state sweep -> queue_first_deploy -> templates::first_deploy) used
none of them. Old `spawn` approval rows are skipped by collect_lenient,
as `init_config` rows were in

swarm-controller
The swarm-level daemon. Where hive-c0re owns the agents on one host, this
owns what is true across hives — so a swarm runs one of them and most hives
leave it off.
Opt-in per host via services.hyperhive.deploy.swarm-controller.enable, which is
deliberately not derived from
services.hyperhive.deploy.hive-controller.enable: turning it on is a statement
about swarm topology, not about whether this host runs a hive.
What it does today
Serves one /health endpoint and holds no state.
That is the whole intent of the first slice. The point is to make the unit
real — service user, runtime and state directories, socket, nginx
reachability — so the swarm-level surfaces that follow have somewhere to land.
Inventing those surfaces before they are agreed would bake in a shape nobody
chose. See the hyperhive.swarm consolidation epic.
Why a unix socket, not a port
The hive-gateway's nginx is the only intended client and reaches the socket through a bind-mount. A listener that is never bound to an address cannot be reached from off-host by mistake.
The socket path is services.hyperhive.deploy.swarm-controller.socketPath, default
/run/swarm-controller/controller.sock, exported to the process as
SWARM_CONTROLLER_SOCKET.
⚠️ The socket's directory is its access control
The socket is 0666. It has to be: nginx runs as a different user and
connect(2) needs write. This matches how hive-c0re publishes the per-agent
sockets, and rests on the same argument — "the bind source dir is per-agent on
host so blast radius is unchanged."
What keeps that safe is that the directory holds one socket. So:
Never point
socketPathat a directory that carries anything else./run/hyperhiveabove all — it holdshost.sock, the host admin socket. Pointing nginx at that directory to reach this socket would put the admin socket within its reach too.
nginx is a host service, so nothing narrows what it can reach except the directory itself — that is the whole of the access control. A unit test pins the default path so a tidying edit fails instead of reviewing cleanly.
RuntimeDirectoryPreserve=yes and the daemon's stale-socket unlink on start are
a pair: preserving the directory without the unlink means bind fails with
EADDRINUSE after a restart.
Packaging
Built by the workspace derivation and extracted as its own package
(nix build .#swarm-controller). Deliberately not in nix/packages'
daemonBins — that list is the core stack and drives the bundle
services.hyperhive.c0re.package points at, so folding this in would put a
swarm-scoped service into every hive's closure.
