      summary: Context use of a conversation
      description: >-
        The detail of one conversation: one entry per delivery, with the
        manifest it came from, the items used, the questions repeated, the
        contradictions and whether a handoff was read. When a delivery could not
        be measured, `not_measured_reason` says why.


        **Authentication.** Console person token with the `analysis`, `vendor`
        role (or admin), or a source key with the `admin` scope.
