nix/module-eval/bao-controller.nix:49 quoted `gatewayHost`'s description
as `hive-matrix.nix`'s own doc. The option now lives in
hive-matrix-service.nix, so the pointer names that file.
Refs #3742
The controller's OIDC client secret (client `swarm-controller`, used for
the queue connection, the auth-bridge bearer and the OTLP push) came from
an operator-placed file, `deploy.swarm-controller.queue.clientSecretFile`,
handed in by `LoadCredential=`.
Now `swarm-secret-publish`, which already copies authelia's minted OIDC
secrets into the store, also publishes this one, to
`swarm/controller/swarm-controller/oidc/client`. That path sits under
`controller/`, which no hive's policy reads. The controller reads it once
at start with its existing store certificate and holds it in memory, as
`swarm_queue_client::ClientSecret::Value`. If the store is down, it
retries for about a minute and then fails the start, so `Restart=` tries
again.
Policy delta: the controller gets `read` on that leaf, and the publisher
gets `create`/`update` on that leaf.
Removed: the `queue.clientSecretFile` option (both spellings, now removed
options with a message), its singleHostSwarm default, the credential and
placeholder, and the path watcher plus its restart oneshot. A controller
without a store identity is now an eval error, because it has no other
way to get the secret.
matrixHomeserverUrl re-derived gatewayHost's own default
(chat.${swarmDomain}) instead of reading gatewayHost itself, so a
deployment that pins gatewayHost away from that default (the exact
case hive-matrix.nix's own option doc describes) left the controller
calling a name nothing serves. Read matrix.gatewayHost directly,
mirroring hive-matrix.nix's ctlHomeserverUrl. Add module-eval cases
that pin gatewayHost and that null it out, alongside the existing
unpinned default case.

An agent's store identity was signed in swarm-controller's memory by a CA
a controller-host unit generated on disk, and the listener never trusted
that CA. Agent leaves now come from the store itself: a `pki-agents` PKI
mount whose root openbao generates internally, so the agent CA's key
never exists outside the store.
- swarm-bao-agent-pki (new, store host, as the bao granter): enables and
tunes the mount, generates the root once (guarded on an empty issuer
list, no replace branch), upserts the `swarm-agent` role (client
certificates named `hive-agent-*` only, 90 days), caches the CA at
/var/lib/swarm-bao-tls/agent-ca.pem and composes the listener bundle.
- The listener's tls_client_ca_file is a new listener-client-ca.pem
(client-ca.pem, then the agent CA). Host cert-auth roles still pin
client-ca.pem, so an agent leaf satisfies no host role. swarm-bao-certs
composes the same bundle before openbao starts.
- openbao reads tls_client_ca_file only at start, so when the bundle
changed after openbao started, swarm-bao-agent-pki restarts
openbao.service in the container; under `seal = "shamir"` it prints
the step instead. Once swarm-bao-certs has a cached CA, later boots
start openbao with it and do not restart.
- The controller policy gains exactly `update` on
pki-agents/issue/swarm-agent. mint_and_verify now asks that role for
the leaf (the store generates the key), writes the agent's cert-auth
role pinning the issuing CA bao returned, and writes the agent's
policy as render_agent alone: the hive-shared queue credential stanza
is gone.
- deploy.bao.agentPkiRoleName (must start `swarm-`, asserted with the
other pki role names); swarm-controller gets
SWARM_CONTROLLER_AGENT_PKI_MOUNT/_ROLE from the deploy.bao options.
Deleted: swarm-controller-agent-ca and its options (agentCaFile,
agentCaKeyFile), env, LoadCredential entries and assertion;
agent_identity's Authority, rcgen signing and validity window; the
rcgen and time dependencies of swarm-controller (rcgen leaves the
workspace); policy::render_agent_with_queue and its tests. The CN-prefix
assertion policy.rs said was owed is not: agent and host roles pin
different CAs.
Migration is re-creating each agent after deploy; that overwrites the
stale role and policy.
Closes#4756
A `MintAgentMatrixAccount` node creates the agent's account on the swarm's
homeserver with the swarm appservice token, stores its token at
`swarm/agents/<agent>/matrix/main`, and reads it back with whoami before
reporting success. It is a root of agent creation, `after_any` into the
deploy, and a five-minute backfill over every agent with a store identity
queues the same node — the shape of the forge-token mint.
The decision reads the stored token back rather than only checking that one
is stored: the swarm and a hive both pin the device `hyperhive-<agent>`, so
each login replaces the other's token. A failed read plans nothing, so an
outage never rotates every agent's token.
`matrixHomeserverUrl` now defaults to the swarm's `chat.` vhost, since the
mint is what consults it.
The single module-eval derivation forced ~62 full nixosSystem
fixtures live at once to compute its cases list: 10.6GB peak RSS /
5m25s to evaluate, by far the dominant cost in nix flake check.
Splits it into 21 independent checks.module-eval-* derivations
(1-7 fixtures each) sharing builders/helpers via module-eval/lib.nix,
so no single derivation needs more than a handful of fixtures live
at once. A few cases spanning two clusters carry a small duplicated
fixture rather than threading shared state through lib.nix.
