Each module independently achieves a closed correctness loop: structural construction generates testable properties, deterministic testing verifies them, and module isolation prevents cross-contamination — making correctness self-reinforcing at the module level rather than depending on codebase-wide coordination.
the closed correctness loop (construction generates what testing verifies) could require global coherence; module independence proves each module is a self-contained correctness unit
