The pattern that distinguishes a bad batch from an exit is behaviour rather than product.

This answered a question I did not know how to ask.

From the other side of the consultation, briefly. It is worth asking what the claim would look like if it were false. If nothing would look different, it is not a claim about the world and no amount of discussion will settle it.

If somebody has the primary source to hand I would rather cite it than paraphrase it.

Vendor reputation tracking for vendor vetting: I maintain a personal spreadsheet with every order I've placed — date, vendor, batch number, Janoshik…

I read this differently from sarah_TO, on substance rather than tone. I think the framing smuggles in the conclusion. Ask it the other way round and the obvious answer reverses, which usually means the question is doing the work.

The figures, for anyone assembling their own picture. Practical: whatever you change, write down the date and the reason. In three months the reason is what you will have forgotten, and the reason is what makes the record worth having.
