Variable ForwardAction`Const`

ForwardAction: {
    Deliver: ForwardAction;
    Flood: ForwardAction;
    Relay: ForwardAction;
} = ...

What to do with a packet bound for a given node.

Provided as a runtime object plus a matching string-union type so it works as both a value (ForwardAction.Relay) and a type annotation.

ReadonlyDeliver: ForwardAction

The packet is for this node; hand it to the application.
ReadonlyFlood: ForwardAction

No route is known; fall back to flooding the packet.
ReadonlyRelay: ForwardAction

A route is known; unicast the packet to the next hop reported alongside.
