Connection preference policy (ADR-0005 Phase 1).

Controls which transport paths are tried and in what order when connecting to a peer. The default strategy is "direct_then_relay".

Fields

strategy: Option<String>

Strategy string.

Value	Description
direct_only	TCP only; no UDP, no relay.
direct_then_relay	TCP, fall back to relay. (default)
direct_then_udp_then_relay	TCP → direct UDP → relay.
direct_then_punch_then_relay	TCP → UDP → hole-punch → relay. (Phase 3)
relay_only	Skip direct paths; use relay immediately.

direct_tcp_timeout_ms: Option<u64>

Timeout for a direct TCP connect attempt (ms).

direct_udp_timeout_ms: Option<u64>

Timeout for a direct UDP session attempt (ms).

punch_timeout_ms: Option<u64>

Total time budget for relay-coordinated UDP hole punching (ms). Phase 3.

heartbeat_interval_ms: Option<u64>

Interval between framework heartbeat probes for active peers (ms).

heartbeat_timeout_ms: Option<u64>

Maximum time without inbound peer activity before the route is unresponsive (ms).

reconnect_base_delay_ms: Option<u64>

Delay before the first automatic reconnect attempt (ms).

reconnect_multiplier: Option<f64>

Exponential multiplier applied after each failed reconnect attempt.

reconnect_max_delay_ms: Option<u64>

Maximum delay between automatic reconnect attempts (ms).

reconnect_max_attempts: Option<u32>

Maximum consecutive reconnect attempts before automatic retries stop.

reconnect_jitter_ratio: Option<f64>

Symmetric jitter ratio applied to reconnect delays, in the range 0.0..=1.0.
