ReadonlyconversationReadonlyinputsReadonlyoutputsReadonlyparentReadonlystateReadonlyturnThis plugin's entries of a kind on the branch of the turn the call runs in ([] outside a conversation).
Keep an entry of this plugin at the turn the call runs in (outside a conversation, a TypeError).
A conversation's turn ended, before its end is recorded (so the next turn, which waits for that end, sees what this hook keeps):
stateisdone,failedorstopped.turns(): the done turns of its branch, this one last when it is done.
