Covenants Question - Lab Safety

Regarding Lab Safety: I'd argue that it mandates a minimum botch dice of one.

Justification: The Golden Cord of the familiar reduces botch dice, minimum one. In Covenants, it says that having a familiar in the lab increases safety (noting that this is a restatement of the gold cord rules). Combining these two, I'd put forth that this means Safety still can't entirely eliminate the chance of a botch, should a zero come up.
