Detailed Description

The live collaborators a route plug-in needs, handed to it at registration time.

A plug-in's RegisterRoutesFn receives this by const reference. The referenced objects (DeviceManager / MonitoringManager) and the storage backing corsOrigin all outlive the running server, so a handler may safely capture the individual fields it needs — but it must **never capture the RouteContext itself**, which is a temporary that dies once registration returns. Capture the fields instead:

void registerRoutes(uWS::SSLApp& app, const mm::api::RouteContext& ctx) {
  app.get("/api/example/devices", [&dm = ctx.deviceManager, cors = ctx.corsOrigin](
                                       auto* res, auto* /*req*/) {
    mm::api::sendJson(res, cors, summarize(dm));
  });
}
