/bg (formerly /background, which is retired) keeps the existing semantics: spawn a fresh, independent agent session in the background. /btw is now its own command matching the convention other harnesses use: ask a quick side question ABOUT the current conversation without interrupting it. A one-shot auxiliary LLM call (main model by default, overridable via auxiliary.side_question.* in config.yaml) answers from a read-only transcript snapshot — the live session's history, role alternation, and prompt cache are untouched, and the current turn keeps running. Surfaces wired: CLI (inline mid-run dispatch), gateway (all messengers, busy-dispatch table + idle dispatch, i18n across all 17 locales), TUI (prompt.btw RPC + btw.complete event), Discord native slash, relay command manifest, desktop exec routing, docs (EN + zh-Hans).
