But they thought it was properly received. This was a computer bug. Function updateDockingState() executed and returned exactly what it was supposed to, but it never properly updated the value of variable DOCKED, so function checkIfDocked() later returned False when it should have returned true. The exact nature of the bug and how it went unnoticed is yet to be determined, but the issue is not with the theory of operation. No integration is going to fix that. Are you proposing that a manual review of every line of code should be part of the docking procedure? It is amazingly presumptuous to assume you know how to make a safe spacecraft better than a literal space agency.
