Add swarm.peers.<domain>.caCert (path to a peer hive's root CA PEM),
trusted everywhere the hive's own internal CA is — so a self-signed
peer hive can federate (matrix) and any in-hive consumer validates its
certs.
Mechanism (reuses the existing hive-CA embedding): the meta-flake
renderer embeds a LIST of CA files next to each agent's flake —
hive-ca.pem (the hive's own self-signed CA, when active) plus each peer
caCert as peer-ca-<N>.pem — and emits them all in
security.pki.certificateFiles, so every agent trusts them at build
time. The matrix container trusts the same peer CAs for federation TLS.
Nothing is installed in the host trust store; the certs live in the nix
store (no mutable host file).
- meta.rs: embedded_ca_files() = hive CA + peer CAs (from new
HIVE_PEER_CA_PATHS env); ca_embed_state() tracks the list (content +
add/remove); sync_agents materialises + stages the list; render emits
the multi-entry certificateFiles. Tests cover hive-only / hive+peers
/ peers-only / none.
- hive-c0re.nix: HIVE_PEER_CA_PATHS service env (colon-joined caCerts);
caCert / certFingerprint option docs updated to the hive-wide scope.
- hive-matrix.nix + docs/swarm.md: scope + comment updates.
certFingerprint stays the c0re-only leaf-pin path.
