  title: Meta Get Current User Feed
  summary: Resolve the current user from the access token and read their timeline feed.
  description: >-
    Identifies the user behind the supplied access token with the /me node and
    then reads that user's feed of timeline posts. Because the Graph API feed
    edge is keyed by user id, the workflow first resolves the id rather than
    assuming the caller already knows it. Every step inlines its request so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
