A background bed under a caller's turn

[robert-dean]

From the raw idea list that lived at todo: unscoped, undesigned, and not checked against the tree. It earns a design by being scoped against real code.

What the foley line on the raw list was actually asking for, and the one part of it still open after the soundboard landed on 2026-08-26:

A dog barking BEHIND somebody is not a pad: a pad is a sound at a MOMENT, and this is a bed running under a whole turn, so it wants AudioJoin.overlays given a SPAN instead of an anchor. MAX_OFFSET_MS names that boundary in as many words — past about three seconds a sound starting before the words end has stopped being the same moment and become a second thing happening

And the other open half of the same line: no stock pack ships, by decision (docs/internals/render.md § "Pads"), so what is left there is sourcing verified CC0 audio, which is a research task with a legal edge rather than a coding one.
