The combination of standalone stdlib-only modules and explicit time injection creates conditions favorable to hermetic, deterministic testing in several SDI implementations — modules can be verified without external services due to their self-contained design, and the three systems using time injection can be tested without time mocking. However, not all 25 modules inject time, and inconsistent defaults at integration boundaries limit how uniformly this property holds across the full codebase.
standalone modules eliminate infrastructure dependencies; time injection eliminates non-determinism — together they make every module fully reproducible without any test infrastructure
