Macros
ACDS Protocol Constants
#define	ACIP_MAX_SESSION_STRING_LEN 48
	Maximum session string length (e.g., "swift-river-mountain" = 20 chars)

#define	ACIP_SESSION_EXPIRATION_MS (24ULL * 60 * 60 * 1000)
	Session maximum lifetime (24 hours in milliseconds) Note: Sessions are actually cleaned up after 3 hours of inactivity (last_activity_at), but expires_at serves as an absolute maximum lifetime.

#define	ACIP_DISCOVERY_DEFAULT_PORT OPT_ACDS_PORT_INT_DEFAULT
	Discovery server default port (use OPT_ACDS_PORT_INT_DEFAULT from options.h)

#define	ACIP_HOST_DEFAULT_PORT OPT_PORT_INT_DEFAULT
	Default port for discovery mode hosts (use OPT_PORT_INT_DEFAULT from options.h)

#define	ACDS_OFFICIAL_SERVER_HOSTNAME "discovery-service.ascii-chat.com"
	Official ACDS server hostname (automatic HTTPS key trust)

ACDS Ring Consensus Protocol (New P2P Design)
NEW ARCHITECTURE: Proactive future host election every 5 minutes. Participants form a virtual ring and rotate who collects NAT data. Every 5 minutes, a new "quorum leader" emerges with complete knowledge and elects the future host. This pre-elected host is announced to all participants so they know who will take over if current host dies. Benefits: No election delay when host dies (future host already known) Fresh NAT data every 5 minutes (not stale) Automatic rotation ensures fair load (each participant gets a turn) Ring topology enables P2P coordination without central ACDS
