Perhaps the 84 second burn overflowed the integer (2^6) and was caught by a 2^7s check (127s)

The tweet you link didn't indicate that. It said that an engine failure likely caused the overrun, running for 127 seconds instead of the planned 84. Why would something have a 2^7 int size check?

Edit: Quoted

The head of Roscosmos Yuri Borisov said that the main cause of the #Luna25 crash was an engine failure. Instead of the planned 84 seconds, he worked 127 seconds.

Am I missing something?
