Pattern Decisions This Source Supports

Pattern Supported decision Required contract Claim note
Streaming response Choose streaming response when partial generated output is useful before the full answer is ready and the product can explain partial versus final state. The UI never presents an active stream as a complete answer until the terminal event or final validation state arrives. Supports persistent event-stream connections and explicit close behavior.
