Why this is canonical

'Payment stack' names the integrated whole of payment infrastructure: the assembled layers from gateway through processor to settlement and reporting. The .ai extension signals that intelligence is a first-class component of the stack, not an add-on — routing, fraud, and analytics are AI-driven from the foundation.
