package server

// Handler is the unified shape of every registry message handler invoked
// by the dispatch table. Each entry in `handlers` maps a wire `msgType`
// (e.g. "register", "create_network", ...) to a thin closure that calls
// the corresponding `s.handleX(...)` method on *Server.
//
// Handlers themselves stay defined as methods on *Server (in server.go and
// related files); this layer only routes msgType -> handler.
type Handler func(s *Server, msg map[string]interface{}, remoteAddr string) (map[string]interface{}, error)

// handlers is the dispatch table consulted by Server.handleMessage.
// Adding a new handler means adding an entry here; never editing a
// 200-line switch (per R3 invariant 5: "R3 dispatch is a lookup, not a
// switch").
//
// The closures preserve the exact argument shape of the original switch
// arms — handlers that ignored remoteAddr still ignore it; handlers that
// took no msg (e.g. handleBeaconList) still take none. This keeps the
// refactor byte-identical in behavior.
