Prompt QueueArea: what it touches
In DevelopmentKind: in v2.1.247,
In DevelopmentSection of the release
A wait flag runs end to end through prompt submission with no caller setting it in this build.
What
Submitting a prompt can now carry a "wait" marker that follows the prompt through queuing and into the query pipeline, and that lets an otherwise-empty submission through instead of being discarded as a no-op. Nothing in this build turns it on, so no user action reaches it yet.
Details
The flag defaults to false at every point it is read.
Without it, an empty submission is still dropped and recorded as an empty prompt submit.
