/*
* XCE Controller HA — role management and election (P1).
*
* P1-1 audit: the existing create_ssl_context() + iomgr_set_ssl_ctx() path
* in cluster.c (line 559, set at line 583) covers all controller-to-controller SSL.
* HA listeners (heartbeat, election probe, replication accept) reuse the same
* ssl_ctx already installed on c->iomgr.
* No new TLS infrastructure is needed — XCE runs on a trusted management LAN.
* Peer identity is validated by host:port match against the --peers candidate list.
* See design doc Part 5.9 and memory: Persistence & HA Trusted LAN Decision.

/* Full struct definitions and API declarations added in P1-2. */
