  * Derive the Web receipt for one dispatch from its owning stream segment.

+ * A dispatch inside an inherited fork prefix folds from its nearest preceding

  * @param events - Complete contiguous Session log.
  * @param dispatchSeq - Exact event seq to present.
  * @param seedLength - Inherited fork prefix length.
