      summary: Retract an assertion
      description: >-
        Retracts one assertion. The profile component is recomputed and may
        split; facts and objects follow their handle of origin, so memory lands
        with the right person on its own. Affected packs are recompiled.


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