Function sendEvent

internal/llm/llm.go:343–350

sendEvent puts e on out, bailing if parent cancels first, so a slow or vanished consumer after Ctrl+C can't wedge the stream goroutine on a full buffer.

(parent context.Context, out chan<- Event, e Event)

	defer resp.Body.Close()

	// Idle watchdog: bufio.Scanner.Scan() ignores context, so a server that
	// stops sending after 200 OK would wedge readSSE forever. Closing the body
	// from the timer unblocks the in-flight Read; readSSE then returns and we
	// surface a stall. parent isn't cancelled, so (unlike Ctrl+C) the error
	// reaches the user. readSSE resets the timer on every frame.
