If Cael accepted her from this farce, then he's incompetent.
If he was testing the lady, he should have heard about the fuck up with the materials. For the madam to gather MORE food supplies on the same budget, that's undeclared income or theft from other parts of the household. Of course, she could explain it, but that is still an ameliorating factor rather than a perfect score.
Nothing what the madam did was wrong, but not declaring it should have been very, very suspicious.
