CDS Hooks Card Simulator

Teaching reproduction · no live hook

In the CRD→DTR relay, a payer's decision-support service answers an order-sign hook with cards — one of which can carry a type:"smart" link that launches the DTR app. This simulator renders the shape of such a response so you can see the relay without a hook ever being called. Paste a response or load the curated synthetic example; nothing is fetched, executed, or applied.
