agentsop-streaming-output

Enhancement-overlay decision protocol for STREAMING the output of long-running LLM / agent runs from the *backend*, not just wiring a typing animation in the UI. Activates when a coder agent must stream final tokens to a chat client, surface intermediate agent steps (which tool, which node, partial reasoning), emit custom tool-progress events, choose a transport (SSE vs WebSocket), or decide what to do when the client disconnects mid-stream. The langchain / langgraph skills mention stream modes but stop at "you can stream"; this skill encodes *what to stream, over what transport, and how to fail safely*.

> This is an **ENHANCE overlay**: it sits on top of `[[agentsop-langgraph]]` (which
> names the four stream modes but treats streaming as one of ten operations) and
> `[[langchain]]`. Read those for the orchestration; read this for the
> streaming SOP. Cross-link: `[[agentsop-langgraph]]` OP-8.
