Deterministic and dependency-free on purpose: these rules are the part of pairing worth testing, and a rule that needs a database or a model to exercise stops being tested honestly. score and confidence stay separate throughout. A pair can be a strong relationship derived by a weak method; the approval queue gates on the derivation, not on the relationship.
