Detailed Description​

template <typename T >
class chronon::AsyncFifoCircuit;

Finite dual-clock circuit, independent of the scheduler. All state is private and owned here. beginEdges snapshots pre-edge remote Gray pointers; commit updates both domains from those snapshots (nonblocking-assignment semantics).
