**Header:** `ClikaRT/runtime/serving.h`

One streamed chunk of a session's output. [`final`](./ResponseChunk.md#final)` == true` marks the last chunk of a cleanly finishing session's stream. Driving a model directly, that chunk carries the finishing step's outputs when it produced any (a finish with no outputs delivers an empty final marker instead); a [`Pipeline`](./Pipeline.md)'s stream always terminates with one empty final marker, the payload rides `on_complete`. An erroring or cancelled session never marks a chunk final: `on_complete` (or the blocking retrieval) is the authoritative terminal signal in every case.
