Status: IN
Construction-based correctness eliminates runtime validation (no defensive checks at function boundaries), while submission-optimized isolation eliminates integration safeguards (no cross-module contracts to enforce) — together they remove both categories of defensive code that engineering discipline would normally require, explaining the repo's characteristically lean function bodies.
Two independent elimination mechanisms (construction removes validation, isolation removes integration testing) jointly explain the complete absence of defensive code
