Forward-only design enforces no-regression guarantees independently at three architectural layers: domain-level state machines contain temporal gaps through irrevocable transitions, execution-level stream processing achieves exactly-once through coordinated dedup and finalization, and execution-level task pipelines maximize forward progress through control-data separation — the no-regression principle is layered across the architecture, not singular.
three independent architectural layers each instantiate forward-only independently
