findRewindSends
findRewindSends(
world,step):SendsAround|undefined
The two sends around the room’s step, for a system that reads many
entities at one step with readSentPlace: both the oldest within a
second of the last for a step older than any, as in a young room or
across a gap while it stood empty. Undefined where the world stands as
it is now: for a step past the last send, at the room’s step or past
it, and in a world with no sends, such as a page’s. Written in place:
read it at once.
