hive-sock-client: each attempt now bounds connect (5s), write (10s) and the wait for the response (60s by default). The response bound is per call through the new `request_within`, which hive-agent's serve-loop `Recv` uses with its 180s long-poll plus 30s headroom. A response timeout is terminal rather than retried: the server holds the request, so a retry re-sends something it may still act on and multiplies the wait by the backoff schedule. Outbound HTTP: the matrix login/whoami clients in swarm-controller and hive-c0re's dashboard (5s connect, 30s request), the authelia-bridge client (5s/30s; ensuring an identity runs an argon2 hash first) and the ci-runner forge calls (5s/15s, config_pr_poll's forge budget) get a connect_timeout and a request timeout. Timeout errors name the bound that fired. hive-agent's unix-socket extra web proxy bounds the connect (5s) and the wait for the response head (30s, the http sibling's budget); the body read stays unbounded.

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.
