Cross-hive trust was O(n²) hand-pinning: every hive had to name every peer's CA. A swarm root makes it O(1) — trust the root once and every present and future peer validates. The root is generated by a new `swarm-ca` unit on a single-host swarm and operator-provided otherwise; `swarm.ca.autoConfigure` picks between them and derives its default from `swarm.peers` being empty, so "all on one host" is read off the deployment rather than remembered. Both modes produce the same artifacts in the same places, so splitting hosts later is moving the service dirs, not switching code paths. The root key never enters the nix store, and the root is never regenerated automatically — replacing it invalidates every peer at once. Each hive CA carries `nameConstraints` pinned to that hive's domain, so a leaked hive CA can only mint names inside its own subdomain, enforced by verifiers rather than by convention. `ca.pem` was serving as both the issuer and the anchor consumers trust; those are the same file only while it is self-signed. openssl will not terminate a chain at a trusted cert that isn't self-signed (rustls and Go will), so the promotion would have broken some consumers and not others. `hive-tls-ca` now also writes `trust-bundle.pem` — the hive CA plus whatever it is rooted at — and every anchor consumer reads that: agents, the CI and forge containers, and the peer-config recipe. On a hive with no swarm root the bundle is just that CA, so nothing consuming it needs a mode to branch on.

# The full hyperhive host stack, pulled together in one place — this
|
|
# is what the flake exports as `nixosModules.default` (wrapped with
|
|
# the package/source wiring; see flake.nix). One import covers
|
|
# everything; `services.hyperhive.enable = true` turns the stack on.
|
|
#
|
|
# The forge is mandatory — hive-c0re mirrors every agent's applied
|
|
# config repo into it and it's the canonical store for the meta flake
|
|
# + `internal/*` repos, so there's no enable toggle; it deploys with
|
|
# hyperhive itself. hive-matrix is opt-in (off by default). All
|
|
# subsystems rely on `services.hyperhive.domain`, which is required
|
|
# (asserted in hive-network.nix) whenever hyperhive is enabled.
