parking lot
In discussion, a space set aside in a corner of a desk or whiteboard to temporarily hold off on a topic that is not deemed appropriate for discussion at this time. It is said to have the effect of avoiding confusion and unnecessary discussion. It is used to isolate off-topic topics, but when the discussion progresses, the topics reserved in the parking lot may be useful.

Using Jiro Kawakita's vocabulary, that's where you'd put ape.
Discussions in this period were voice communication where only one thing could be said at a time, so it was easy to miss the "might have something to do with it" that came from associations with the topic.
Record it and keep it close by so you can use it later.
