Append Message

Talk appends what was said and decided OUT LOUD — spoken turns, resolved decisions, the call receipt — into the same thread as the typed turns, so a conversation survives the panel closing. content is the plain sentence the model reads as conversation; meta is how the thread renders the row (kind: spoken | decision | receipt). Typed turns are persisted by the model call itself, never through here.

Trust: a spoken row is the caller's word, like an imported transcript. A receipt row is materialised server-side and an applied decision is refused outright (see _materialise and app.chat_attach) — the browser cannot claim a change it did not make, relabel one, or attach one twice.
