     * row's recorded selection — a same-runtime model change never updates that row. The tip's sidecar
     * `kind:"origin"` record wins when Winter wrote one; otherwise the tip's own `message.model` (a
     * claude-written turn) is read directly. The recorded selection is the fallback ONLY when the lineage
     * has no assistant entry at all (a session with no reply yet).
