I'm not about to read that wall of text, but search doesn't find the phrase "inbound" so I'm going to guess you didn't try united.com. It's pretty clear for 3587 BUF-IAD "Status: Delayed due to Late inbound aircraft arrival (Arrived Gate 1 Hour 43 Minutes Late)"
The plane, N351PH, started the day 3h late out of Charleston, WV as UA5015. That first flight of the day was delayed due to mx: "Status: Delayed due to Aircraft maintenance (Arrived Gate 2 Hours 37 Minutes Late)"
But that's irrelevant to your flight, which was delayed by the late inbound aircraft.
