```
tmux.Server.SetBuffer(ctx: context.Context, request: SetBufferRequest) -> error
```

SetBuffer stores or appends exact string data without refreshing models. It mutates the selected paste buffer; completed stderr is reported as a redacted command error because Data may be secret. Cancellation does not prove that tmux did not store data.
