If your system works ninety-nine percent of the time, you probably think it is healthy. But the one percent you don’t see is where systems actually fail. That tail is where retries, timeouts, and coordination accumulate. It is where latency spikes, failures correlate, and reliability quietly collapses. This piece describes an execution model in which that tail never forms, because recovery is a reset rather than a negotiation. Modern systems often treat reliability as a problem of memory. When something fails, they log, replay, reconcile, and coordinate in order to reconstruct what happened and decide what should happen next. This works at small scale, but as systems grow, recovery paths accumulate inference, shared state, and coordination. Latency grows. Tail behavior worsens. Failures that were once independent begin to correlate. This work explores a different premise. Recovery does not require memory. It requires enforcement. Rather than reconstructing the past to infer correctness, correctness can be enf
