The architecture achieves correctness redundancy through two complementary strategies operating at different granularities: defense-in-depth provides layered guarantees across system boundaries (perimeter normalization ensures clean inputs, structural construction prevents internal corruption), while per-module self-reinforcement creates closed verification loops (structural construction generates testable properties that verify the construction itself).
defense-in-depth (depth 5, unused) and self-reinforcing (depth 8, unused) are independent correctness strategies; combining shows the architecture has both inter-layer and intra-module redundancy
