Is there a way to archive a parent session (and not the child)?

Is there a way to archive a parent session (and not the child)?

Sometimes I will have a parent session (its work is completed), and I want to archive it but it has a child under it.

This would be nice if there is some UX to do that, because it results in unecessary pings from child -> parent and wastes tokens for no reason.

Maybe you could drag sessions to "child" or "un-child" them?

Start by reproducing the session hierarchy behavior on the /chat path with a completed parent session and an active child. Define the UX for archiving only the parent, including whether sessions can be re-parented or un-childed. Done means the parent can be archived without archiving its child and unnecessary child-to-parent pings stop.
