A turn without complete speaker information is not sent; every peer in the fleet workspace is a member, so fleet notes are messages that one search finds, with a retraction message for an undone note (Honcho cannot delete a message); the fleet workspace derives nothing (reasoning, summaries and dreaming off); API keys per workspace are first-class, with a runbook entry for a refused key.
