hive-matrix-daemon now learns which external matrix accounts it has from the swarm secret store, under the agent's own certificate, and the hive push chain for matrix is gone. The daemon lists swarm/agents/<agent>/matrix/ (the `list` its policy grants on its own metadata subtree), reads each account's homeserver from its credential, and brings the accounts up with their tokens from the store. Every two minutes it lists again and exits with 75 when the set of linked accounts changed; the unit restarts on 75 without counting a failure. A listed name whose credential reads as absent is skipped and logged once. At start it removes the matrix-token-<a> / matrix-account-<a>.json pairs a hive delivered (a sidecar marks a pair as delivered; a declared tokenFile keeps its token). Removed: CredentialNotice and the $SWARM.credential.* subject and NATS grant, the controller's publish and its queue precondition on the PUT route, hive-c0re's credential subscription arm and workers/credential.rs, priv_client::write_agent_matrix_token, hive-priv's WriteAgentMatrixToken and its helpers, and the daemon's state-dir account discovery. Kept: WriteAgentGithubToken and the external-forge path (WriteAgentExtraForgeAccount, extra_forges.rs) are untouched, and a declared matrixAccounts tokenFile is still read when the store has no token for that account.

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.
