// Package tsconsensus implements a consensus algorithm for a group of tsnet.Servers
//
// The Raft consensus algorithm relies on you implementing a state machine that will give the same
// result to a given command as long as the same logs have been applied in the same order.
//
// tsconsensus uses the hashicorp/raft library to implement leader elections and log application.
//
// tsconsensus provides:
// - cluster peer discovery based on tailscale tags
// - executing a command on the leader
// - communication between cluster peers over tailscale using tsnet
//
// Users implement a state machine that satisfies the raft.FSM interface, with the business logic they desire.
// When changes to state are needed any node may
// - create a Command instance with serialized Args.
// - call ExecuteCommand with the Command instance
// this will propagate the command to the leader,
// and then from the reader to every node via raft.
// - the state machine then can implement raft.Apply, and dispatch commands via the Command.Name
// returning a CommandResult with an Err or a serialized Result.
