The codebase achieves both correctness and simplicity through the same underlying mechanism: leveraging existing structures (heaps, topics, sorted lists) rather than inventing new ones, so that correctness guarantees of underlying structures are inherited from reuse while construction-time constraints eliminate entire classes of bugs — parsimony and safety are not in tension but emerge from the same design choices.
Structural reuse simultaneously provides correctness (inherited invariants) and simplicity (no new abstractions), making them non-competing goals
