A child greet sends an empty Conversation snapshot, so a kept child's stored analysis is never served.

The root turn answers in the child's thread with reply_comment and its edit_child writes become the thread's result. Each route re-asks storage that the child still belongs to a live root in the same repository and refuses before saving anything when it does not.

The hold now ends with the instruction's own end, and at once when it folds into a waiting turn or is refused. Closing a Chat tells waiting instructions they were skipped.

Repository From 6d78f576ecca73d2f12f7dc591f85e80b73d87c2 Mon Sep 17 00:00:00 2001 From: Maggie Appleton <5599295+MaggieAppleton@users.noreply.github.com> Date: Sun, 11 Oct 2026 12:19:01 +0100 Subject: [PATCH 11/22] Release a child's rooms when its root closes mid-turn A Chat closed during a routed child comment turn never reports the turn's end, so the child room stayed held and its thread kept showing work. The turn's running promise now stands in for that report, and a closed Chat counts as working on nothing.
