A standalone conversation under one minimal header: a tabbed thread switcher over pinned and recency lists, a favorite toggle and a fold for earlier turns, above replies that arrive as small documents with sections, bullets and code artifacts in markdown, yaml, json, typescript and sql, each one folding its working away behind a thought row and listing the sources its inline citations point back to, over a thread held as a tree so a regenerate or an edit adds a version on the fork rail instead of overwriting the turn.
