Subject: [PATCH 1/2] feat: opening a prepared review parks a live agent on it

The inbox epic's last piece: one click brings the session up and leaves an agent listening.
The daemon parks on the session with `agent await`; each question the reader asks runs the
configured agent command once, credential-stripped as for preparation but in the reviewer's
own data directory, told to answer or amend and never to change code or reach the forge.
The wait is re-armed before the answer runs, so the page never shows the gap. The agent
leaves when the page is closed or the session is gone, and the daemon takes it down with
itself. Inbox sessions start with --review, so the server refuses edits as well.

From a908931b7d9b3a14944b8f82570976be1e8b88d2 Mon Sep 17 00:00:00 2001
From: "Fredrik Liljegren (Claude Code Claude Fable 5.1)"
 <fredrik.liljegren@naturalcycles.com>
Date: Thu, 3 Sep 2026 15:45:26 +0200
Subject: [PATCH 2/2] fix: a request the agent could not answer is closed, not
 run again
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A request that comes back unanswered — a timed-out run, an agent that exited without
closing it — would be handed to the same attendant by the server's stale-claim reclaim, and
run again, indefinitely. On a timeout, and when a request is handed over a second time, the
attendant closes it with an aside saying the agent could not answer.
