-``-n`` makes no model call and prints the chats, chat-day batches, local
-dates, cutoff, text bytes, merged message count, and estimated calls.
-The import keeps multiline text, system lines, and omitted-media
-markers. It maps the session's profile name to ``You``. Without that
-name, it keeps the senders as written and says so in the plan. An exact,
-unambiguous local contact or batch name supplies the chat ID when known.
-No network lookup is made.

+The target is the root unless ``--agent NAME`` selects an existing
+direct child. A missing child is refused. The rebuild uses the target's
+log, prompt, cache key, and usage records. The root keeps its history
+when the target is a child. An import or plan is refused while the
+target has pending agent deliveries. Start the daemon and let those
+turns finish before you stop it and try again. This keeps their saved
+log IDs valid.
