Actors read one JSON message per line. Each message has `id`, `from`, optional `reply_to`, and `body`. The broker routes a message with `to`. Without `to`, the broker publishes it to subscribers. A reply is a new message with `reply_to` set to the original ID.

Keep state in `/data` so it survives restarts and upgrades. Read the old data format when you upgrade an actor. Large contexts may omit the oldest whole turns from requests, so you may not see them even though `/data/history.jsonl` stays complete.
