How do I stop a factory changing materials without telling me?

You stop it by having someone on the ground checking the factory. When a factory knows nobody is watching, that is when the material quietly changes. Someone representing you, who can appear any day, keeps them careful. Eyes and ears on the ground is the only real answer.

If this is where you are right now, Factory Verification — I go look myself is the deeper version of this same check.
