+The one-Session ownership decision remains in force. The October refactor follows
+[issue #5745](https://github.com/apache/maka/issues/5745#issuecomment-5933360159):
+the Coordination Agent interprets intent and chooses task operations directly.
+There is no fresh pre-admission routing-model pass or atomic correction operation.
+The sections below retain the earlier routing and replacement design as history;
+the [current domain language](../workhub-domain-language.md) describes the live
+interface. Historical bound decisions and replacement records remain readable for
+recovery.
+
+## October coordination and configuration refactor
+
+- Independent work can create a Session without an explicit user request to create
+  one. Clear continuations reuse an existing Session; ambiguity uses the existing
+  Host selection interaction, including a new-task option.
+- Delegation carries an instruction to the target Session. That Session owns
+  context preparation and execution, including continuation recovery.
+- New Sessions inherit the canonical WorkHub model and thinking configuration.
+  Reused Sessions retain their model. Unavailable target models return an error.
+- WorkHub execution uses the WorkHub permission setting. The assignment snapshots
+  that setting, and the Runtime scopes it to the execution; the saved target
+  configuration is unchanged. The current WorkHub provisioned mode remains bypass.
+- Stop and delegate are separate operations. A partially successful sequence is
+  explained and retried from durable operation facts. Fresh tools expose no atomic
+  correction operation; existing replacement records retain recovery support.
+- Worker questions return missing information immediately. The Coordinator asks
+  the user and sends the answer as another instruction. Result reading and durable
+  completion notifications remain; suspended-question relaying is removed.

Keep the question to one short sentence, for example 为哪项工作生成下一步？. This is read-only selection for drafting, so use AskUserQuestion even though ordinary execution target selection uses select_and_delegate. Never use select_and_delegate for wn: it starts work. Keep the exact mapping from each offered label to the discovered Session identity. Offer all three recent works when available; do not replace the third work with a pagination option. If only one work exists, offer it plus Cancel. If none exist, say no current or recent work was found and invite the user to describe a goal; do not create work.
