``workdir`` is an absolute path, and its default is the home directory.

+ Daemon log
+************
+
+The daemon writes short events with the part prefix and ordered
+``key=value`` attributes. An error cause comes last. Normal events use
+info, failures that can be retried or lose nothing use warning, and
+failures that lose data or stop work use error.
+
+With ``JOURNAL_STREAM`` set, each line carries a syslog priority without
+a time stamp or level word. The user journal can show only warnings and
+errors:
+
+.. code:: console
+
+ journalctl --user -u onechat -p warning
+
+The summary warning names its node. A schedule run has ``late`` only
+when it ran late:
+
+.. code:: text
+
+ <4>onechat: summary failed level=0 index=0: fake failure
+ <6>onechat: schedule ran id=1
+ <6>onechat: schedule ran id=2 late=1m0s
+
+Outside the journal, each line starts with the time stamp and level.

When the session holds a linked device, the daemon connects at its
start. If the first connection fails, it tries again after 2 seconds,
then doubles the wait up to 5 minutes. The inbox and commands stay
-active during each wait. An unlink, logout, or pair command stops these
-retries. After a network failure of an open connection, the library
-connects again by itself. When a disconnection lasts 10 minutes, all
-clients get one notice, and one more when the connection comes back.
-When WhatsApp ends the connection for good, for example because another
-program uses the same session, all clients get a notice at once. When
-the user removes the device in the phone, the daemon deletes the session
-and tells all clients one time.

+*************************
+ Import WhatsApp history
+*************************
+
+Stop the daemon and finish all subagents before an import. Export each
+chat from WhatsApp as a ZIP with ``_chat.txt``. Keep the chat name in
+the ZIP name, such as ``WhatsApp Chat - Example.zip``. Read the plan
+first:
+
+.. code:: console
+
+ onechat import -n CHAT.zip OTHER.zip
+ onechat import CHAT.zip OTHER.zip
+
+``-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.
+
+Each chat and local day becomes one work message marked ``(imported)``.
+Only messages before the first message of the earliest live WhatsApp
+batch enter the import. Live times have minute precision, so the cutoff
+excludes that whole minute. A chat-day already imported is skipped.
+Overlapping chat-days in the supplied ZIPs are refused. Review the
+exports before import: their text goes to the model as chat history.
+
+The import merges the full log in date order and builds its tree with
+real compactor calls, the agent prompt, and the agent cache key. It uses
+a limit of 1,500 calls and the probe's 15-quota-point limit, and prints
+the same usage report. Its estimate is about 1.3 calls per merged
+message, not a cost guarantee. A stopped or failed run leaves the agent
+unchanged. A new run starts over. Success keeps the other agent files
+and renames the old directory to ``agent-backup-TIMESTAMP`` before it
+installs the new one. Keep the backup until the new memory is checked,
+then start the daemon. Message IDs change to their positions in the
+merged log.
