Portable workflow for external PR / issue operations and source-to-public publishing. Use when: a thread is reviewing, triaging, intaking, or advising on an external artifact, or must distinguish outbound sync from a public release. Not for: internal feature work with no external artifact, generic thread orchestration, replacing the external maintainer's own decision, or inventing deployment-specific export commands. Output: grounded provider-neutral subject + verified author/authenticated-identity comparison + adoption five-question answer + correctly separated sync/release custody.
