The app request stack a request is issued through (generateHeaders vs
generateGraphqlHeaders). The edge applies each stack's logged-out identifier
policy from it, and providers pick stack-specific values from it (the GraphQL
stack stamps the incremental priority hint, the GraphQL analytics category, its
form content type and the minimal client library). The resolver never sees it.
