Use this guide when a Codex conversation starts to branch. The goal is to keep the main thread useful as an execution record while still giving tangents, experiments, and clean starts a place to live.
| Need | Use | Why |
|---|---|---|
| Keep doing the current task | Main chat | It stays the source of truth for execution. |
| Ask a tangent or run light research | Side-chat | It helps the main task without changing it yet. |
