The latest ${TASK_DELIVERY_CONTEXT_LABEL} message is runtime-authored and lists background tasks accepted so far from the current turn. They continue independently after this turn.

Continue carrying out the user's request, including starting any remaining background work.

Do not wait for results or report results that are not available yet. End the turn after the acknowledgement.`,TASK_DELIVERY_SETTLED_INSTRUCTION=`Background task reporting\nFor this background-task update, the accompanying ${TASK_DELIVERY_CONTEXT_LABEL} message is runtime-authored and lists the settled tasks in this cohort and their available terminal outputs.

When that work settles, combine its results with any previously withheld results. If there is nothing new and useful to report, reply with exactly ${EMPTY_DELIVERY_SENTINEL}.
