Fields

transport_identity: Option<Zeroizing<[u8; 64]>>

The transport role takes a whole identity, never a bare address: a transport node signs (tunnel synthesis), and RNS 1.4.2 keeps a dedicated persisted transport identity.

pre_configured_destinations: Destinations

app_state: AppState

storage: Storage

The storage layout the engine’s columns run on: GrowableHeap on a std host, Esp32S3 for the PSRAM-backed reference target, or a board-owned fixed layout for an SRAM-constrained application. A type-level choice carried as a value so the recipe owns it and PrnsNode::new no longer assumes one.

request_endpoints: RequestEndpoints

interfaces: Interfaces

persistence: Persistence

on_event: OnEvent
