publish_prepare
Prepare a publish package
Creates reviewable publish packages for an episode or clip. This never publishes externally; a fresh server-bound final confirmation is required before any send and is ordinarily surfaced in the first-party workspace. App-only descriptor visibility does not itself restrict authenticated MCP transport or prove human review. Improved YouTube/LinkedIn/X titles, descriptions, and copy belong in the package here (or in publish_update); the saved episode stays unchanged.
