Muse 8.0 Mac client contains a pending-message editor, reverse engineering finds
RuntimeWire's reverse-engineering of Meta's signed Muse 8.0 Mac package (build 1093405488) found an editor for certain pending messages, with saving edits and approving the action handled as separate operations — a feature ChatGPT's desktop app already has. An editable approval step would let users correct agent-prepared messages without restarting the task. Caveat: this proves the client is built for the flow, not that it is live server-side.
