final class UpsertTruth

Answers whether a value counts as true, in SQL's three-valued logic.

Null is not false: it is unknown, and it stays unknown through NOT. It only stops mattering where the other operand settles the answer on its own — one false makes an AND false, one true makes an OR true — which is what makes these different from PHP's own operators.
