+For async multi requests, Quantum installs the same completion collector used by normal multi requests and also wires your success and error callbacks. For each finished request the collector runs first, so inside your callback `getResponse()` and `getErrors()` already hold that request.

+Those keys are lowercased before storage, so read them back in lowercase too: after `setHeader('X-Token', 'abc')`, `getRequestHeaders('x-token')` returns `abc` and `getRequestHeaders('X-Token')` returns `null`. `setHeader()` adds one entry, while `setHeaders()` replaces the whole tracked set.
 
 This is only a bookkeeping layer for later reads through `getRequestHeaders()`. It does not inspect headers set through unrelated low-level cURL options.

+`getErrors()` is empty when the request worked. It holds an entry when cURL failed to complete the request, and also when the server answered with an HTTP 4xx or 5xx status. A request to a missing page gives:
