For what it’s worth, this discussion is exactly what pushed me to experiment with a small runtime invariant helper for React/JS. The idea wasn’t to replace good modeling or tests, but to fail early when real-world state temporarily drifts away from its intended shape (especially in async or legacy flows). I put a small prototype here if anyone’s curious: https://github.com/vortexshadow678-hash/invariant-guard https://github.com/vortexshadow678-hash/invariant-guard
