Summary

Let child Berd chats explicitly use Auto Balanced or another configured Auto mode through berdctl session create --auto-mode-id <id>. Today, CLI creation uses the Auto default only when harness, model, and persona are all omitted. There is no way to request a mode explicitly.

berdctl info models --harness-id goose now lists Auto modes separately from concrete models. Creation and session metadata report auto_mode_id. Invalid modes and model/harness conflicts fail before workspace or session creation. Existing default behavior stays unchanged; this does not infer settings from the parent chat.

The change preserves the configured provider/model requirement in LAWS/AGENTS.md and the existing first-message queue path in LAWS/CHAT.md.

Related issue

No duplicate found. Extends the Auto model modes introduced in #389.

Testing

Built the berdctl binary and checked session create --help and info models --help; both expose the new mode selection and discovery guidance. No live desktop end-to-end test. The change adds no new UI.
