decode the four types the client kept sending

14303 AskForJoinableAlliancesList and 14107 CancelMatchmake are both genuinely
empty payloads. 516 UpdateLastShownLevelUp is header only, 537 StartMatchmake
carries a vint and a bool. none of them move the home checksum.

that clears the unknown type warnings out of the log.
