the problem occurred at T+80, and was probably noted *after* MECO.

Actually they didn't notice it until the next day when they were reviewing the launch films...MECO + 24 hours or so.

Well, that is after MECO. (Yours is the first confirm I had of that.) But it doesn't really change things. The entry would have been the same if they had found it at MECO +1 hr or MECO +10 days. Once the mains stopped they were doomed. At least they got to enjoy the flight.
