Diversity is material rather than cosmetic: the portfolio covers an immutable scientific value, a mathematical evaluation provider, a stateful equipment session, and a persistent transactional ledger, with different affected problems, interventions, actors, invariants, side effects, and causal paths. All six pairs are independently adoptable opportunities, so no replacement is required."}
