  title: Meta Read User Feed And Identity
  summary: Read a target user's feed and resolve the caller's own identity for context.
  description: >-
    Pulls a target user's profile and feed, then resolves the caller's own
    identity via /me so a consumer can compare the target against the
    authenticated user. The profile read up front confirms access to the target
    before the feed pull. Every step inlines its request so the flow can be read
    and executed without opening the underlying OpenAPI description.
