// envelope, so it is equally trustworthy whether it rejects an ordinary request or the
// dedicated time-fix ping. Apply it directly. Previously a salt that rejected a normal
// request was discarded and the session entered MTProtoStateAwaitingTimeFixAndSalts
// (which gates every outgoing transaction); if the follow-up time-fix ping was then
// lost, nothing re-applied the salt or re-armed a transaction, so the session wedged
// until the DC closed the socket (~90-120s, surfaced to the user as a stuck "Updating").
